CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation application of International Application No. PCT/KR2021/007723, filed on Jun. 21, 2021, which claims priority to Korean Patent Application 10-2020-0089841, filed on Jul. 20, 2020, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     Field 
     The disclosure relates to electronic device for providing the execution screen of an application and a method of operating the same. 
     Description of Related Art 
     For many people in modern times, portable digital communication devices have become essential items. Consumers may want to receive a variety of high-quality services at anytime and anywhere by using portable digital communication devices. 
     In recent years, portable digital communication devices have been implemented in various types (or form factors) in order to improve convenience of use by consumers. Portable digital communication devices implemented in various types may be transformable by consumers and may continue to provide services even in a transformed state. 
     Therefore, in order to facilitate the use of services provided via portable digital communication devices, which are in a transformed state, it is necessary to implement a technology to provide information via the portable digital communication devices, which are in the transformed state, by configuring information in a form convenient for consumers to use. 
     A transformable (e.g., foldable) electronic device may include a plurality of housings and a flexible display disposed on the plurality of housings. When a transformable electronic device is folded while the transformable electronic device displays content (e.g., the execution screen of an application) on the flexible display (e.g., when the relative positions of the housings are changed by a user), the flexible display may be bent, and the transformable electronic device may continue to display the execution screen of the application on the bent flexible display. Accordingly, the content displayed on the transformable electronic device may be visually recognized by the user as being distorted. Alternatively, when the user interacts with the content (e.g., touching) displayed on a bent flexible display, an erroneous input on the content by a part of the user&#39;s body (e.g., a finger) holding a folded electronic device may be caused, which may cause the transformable electronic device to malfunction. 
     SUMMARY 
     Provided are an electronic device and a method of operating the same in which, when the shape of the electronic device (e.g., an angle between housings) is transformed, a content different from a content that has been displayed, is displayed at a position different from the position at which the content has been displayed, so that it is possible to solve the phenomenon in which the content is visually recognized as being distorted. Alternatively, provided are an electronic device and a method of operating the same that configure touch areas for using contents when the electronic device is in a transformed state, so that it is possible to prevent a user&#39;s erroneous input on contents, and malfunction of the electronic device may be prevented in advance.

     The battery  189  may supply power to at least one component of the electronic device  101 . According to an embodiment, the battery  189  may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell. 
     The communication module  190  may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device  101  and the external electronic device (e.g., the electronic device  102 , the electronic device  104 , or the server  108 ) and performing communication via the established communication channel. The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module  190  may include a wireless communication module  192  (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module  194  (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device  104  via the first network  198  (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network  199  (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module  192  may identify or authenticate the electronic device  101  in a communication network, such as the first network  198  or the second network  199 , using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module  196 . 
     The wireless communication module  192  may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module  192  may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module  192  may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module  192  may support various requirements specified in the electronic device  101 , an external electronic device (e.g., the electronic device  104 ), or a network system (e.g., the second network  199 ). According to an embodiment, the wireless communication module  192  may support a peak data rate (e.g., 20 Gbps or more) for implementing eMBB, loss coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or a round trip of 1 ms or less) for implementing URLLC. 
     The antenna module  197  may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device  101 . According to an embodiment, the antenna module  197  may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the antenna module  197  may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network  198  or the second network  199 , may be selected, for example, by the communication module  190  from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module  190  and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module  197 . 
     According to various embodiments, the antenna module  197  may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band. 
     At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)). 
     According to an embodiment, commands or data may be transmitted or received between the electronic device  101  and the external electronic device  104  via the server  108  coupled with the second network  199 . Each of the external electronic devices  102  or  104  may be a device of a same type as, or a different type, from the electronic device  101 . According to an embodiment, all or some of operations to be executed at the electronic device  101  may be executed at one or more of the external electronic devices  102 ,  104 , or  108 . For example, if the electronic device  101  should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device  101 , instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device  101 . The electronic device  101  may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device  101  may provide ultra low-latency services using, e.g., distributed computing or mobile edge computing. In another embodiment, the external electronic device  104  may include an internet-of-things (IoT) device. The server  108  may be an intelligent server using machine learning and/or a neural network. According to an embodiment, the external electronic device  104  or the server  108  may be included in the second network  199 .

       FIGS.  2 A,  2 B,  2 C,  2 D,  2 E,  2 F,  2 G,  2 H,  2 I,  2 J, and  2 K  are views for describing various examples of an electronic device including at least two housing structure and a flexible display according to various embodiments. 
     According to various embodiments, an electronic device may include two or more housing structures and a flexible display, wherein a portion of each of the housing structures is connected to a hinge such that relative positions of the housing structures are changeable (or rotatable) according to the pivoting of the hinge. 
     According to various embodiments, the flexible display may be disposed on the two or more housing structures, and may be bent depending on the rotated states of the housing structures. The rotated states of the housing structures are described in more detail below. 
     According to various embodiments, various types of electronic devices may be formed depending on the two or more housing structures, the flexible display, and the rotated states of the housing structures. For example, as illustrated in  FIGS.  2 A,  2 B,  2 C,  2 D,  2 E,  2 F,  2 G,  2 H,  2 I,  2 J, and  2 K , the various types of electronic devices may include a type in which two areas are formed in an electronic device and/or a flexible display of the electronic device (e.g., a half-fold type as shown in  FIG.  2 C ), a type in which three areas are formed in an electronic device and/or a flexible display of the electronic device (e.g., a tri-fold type as shown in  FIG.  2 A , a Z-fold type as shown in  FIG.  2 B , a single open gate-fold type as shown in  FIG.  2 F , a type in which four areas are formed in an electronic device and/or a flexible display of the electronic device (e.g., a double parallel reverse-fold type as shown in  FIG.  2 D , a double parallel-fold type as shown in  FIG.  2 E , a double gate-fold type as shown in  FIG.  2 G , a roll-fold as shown in  FIG.  2 H , an accordion-fold type as shown in  FIG.  2 I , a half-fold-then-half-fold type as shown in  FIG.  2 J ), and a type in which a greater number of areas are formed in an electronic device and/or one or more flexible displays of the electronic device (e.g., a half-fold-then-tri-fold type as shown in  FIG.  2 K ). 
     An electronic device may include housing structures, which are rotatably connected to each other, and a flexible display. The housing structures may be rotated to form a corresponding type of the electronic device. In some embodiments, in a case of an electronic device including two or more housings and two or more displays disposed on each of the housings, respective displays of the electronic device may form an angle relative to each other depending on the rotated states of the housings. 
     Hereinafter, an electronic device according to various embodiments and a method of operating the same are described by taking an electronic device including two housings and a flexible display as an example. Accordingly, the operation of switching the execution screen of an application of an electronic device (e.g., changing the size and/or position of objects and/or contents, and configuring touch areas) to be described below may also be applicable to a description of an electronic device including three or more housings and/or two or more flexible displays, without deviating from the scope of the present disclosure. That is, the present disclosure is not limited in this regard. 
     Although the electronic devices may be described as having a single display disposed on a plurality of housings, different displays may be provided on the plurality of housings. Accordingly, a description of an electronic device according to various embodiments as described below and a method of operating the same may also be applicable to a description of an electronic device including two or more housings and/or two or more displays, which may be disposed on the housings. For example, a description of an area of a flexible display corresponding to one housing may be applicable to a description of a display corresponding to one housing among a plurality of displays provided in an electronic device. 
     Hereinafter, an example of an electronic device  101  is described with reference to  FIGS.  3 A to  3 C . 
       FIG.  3 A  is a view illustrating an electronic device  101  in an unfolded state, according to various embodiments.  FIG.  3 B  is a view illustrating the electronic device  101  in a folded state, according to various embodiments.  FIG.  3 C  is an exploded perspective view of the electronic device  101 , according to various embodiments. 
     Referring to  FIGS.  3 A and  3 B , in some embodiments, an electronic device  101  may include a foldable housing  300 , a hinge cover  330  configured to cover the foldable portion of the foldable housing, and a flexible or foldable display  200  (hereinafter, display  200 ) disposed in a space defined by the foldable housing  300 . Herein, the surface on which the display  200  is disposed may be referred to as a first surface or the front surface of the electronic device  101 . In addition, the surface opposite the front surface may be referred to as a second surface and/or the rear surface of the electronic device  101 . In addition, a surface surrounding the space between the front surface and the rear surface may be referred to as a third surface or the side surface of the electronic device  101 . 
     In some embodiments, the foldable housing  300  may include a first housing structure  310 , a second housing structure  320  including a sensor area  324 , a first rear cover  380 , and a second rear cover  390 . The foldable housing  300  of the electronic device  101  is not limited to the shape and assembly illustrated in  FIGS.  3 A and  3 B , and may be implemented by a combination and/or an assembly of other shapes and/or components. For example, in other embodiments, the first housing structure  310  and the first rear cover  380  may be configured integrally with each other, and the second housing structure  320  and the second rear cover  390  may be configured integrally with each other. 
     As shown in  FIG.  3 A , the first housing structure  310  and the second housing structure  320  may be disposed on opposite sides about a folding axis (e.g., the axis A), and may have generally symmetrical shapes about the folding axis A. As described below, the first housing structure  310  and the second housing structure  320  may have different angles or distances therebetween depending on whether the electronic device  101  is in the unfolded state, the folded state, or the intermediate state. In some embodiments, the second housing structure  320  may further include the sensor area  324  in which various sensors may be disposed. Alternatively or additionally, the first housing structure  310  and the second housing structure  320  may have mutually symmetrical shapes in other areas. 
     Continuing to refer to  FIG.  3 A , the first housing structure  310  and the second housing structure  320  may form together a recess that accommodates the display  200  therein. In some embodiments, the recess may have two or more different widths in a direction perpendicular to the folding axis A, due to the sensor area  324 . 
     For example, the recess may have (1) a first width W 1  between a first portion  310   a  parallel to the folding axis A in the first housing structure  310  and a first portion  320   a  formed at an edge of the sensor area  324  in the second housing structure  320 , and (2) a second width W 2  between a second portion  310   b  in the first housing structure  310  and a second portion  320   b , which is parallel to the folding axis A but does not correspond to the sensor area  324 , in the second housing structure  320 . As such, the second width W 2  may be greater than the first width W 1 . That is, the first portion  310   a  of the first housing structure  310  and the first portion  320   a  of the second housing structure  320 , which are asymmetrical with each other, may form the first width W 1  of the recess, and the second portion  310   b  of the first housing structure  310  and the second portion  320   b  of the second housing structure  320 , which are symmetrical to each other, may form the second width W 2  of the recess. 
     In an embodiment, the first portion  320   a  and the second portion  320   b  of the second housing structure  320  may be located at different distances from the folding axis A. That is, the widths of the recess are not limited to the illustrated example. In various embodiments, the recess may have multiple widths due to the shape of the sensor area  324  and due to the asymmetric portions of the first housing structure  310  and the second housing structure  320 . 
     In an embodiment, at least a portion of the first housing structure  310  and at least a portion of the second housing structure  320  may be formed of a metal material or a non-metal material having a rigidity of a level selected in order to support the display  200 . 
     According to an embodiment, the sensor area  324  may have a predetermined area adjacent to one corner of the second housing structure  320 . However, the arrangement, shape, and size of the sensor area  324  are not limited in this regard. For example, in other embodiments, the sensor area  324  may be disposed at another corner of the second housing structure  320  and/or in any area between the upper and lower end corners. 
     In an embodiment, components embedded in the electronic device  101  to perform various functions may be exposed to the front surface of the electronic device  101  through the sensor area  324  and/or one or more openings provided in the sensor area  324 . The components may include various types of sensors. The sensors may include, but not be limited to, at least one of, for example, a front camera, a receiver, and a proximity sensor. 
     The first rear cover  380  may be disposed on one side of the folding axis in the rear surface of the electronic device, and may have, for example, a substantially rectangular periphery. The periphery may be enclosed by the first housing structure  310 . Similarly, the second rear cover  390  may be disposed at the other side of the folding axis on the rear surface of the electronic device, and the periphery of the second rear cover  390  may be enclosed by the second housing structure  320 . 
     Continuing to refer to  FIGS.  3 A and  3 B , the first rear cover  380  and the second rear cover  390  may have substantially symmetrical shapes about the folding axis (the axis A). However, in some embodiments, the electronic device  101  may include a first rear cover  380  and a second rear cover  390  having various shapes that may not necessarily be mutually symmetrical shapes. In other embodiments, the first rear cover  380  may be configured integrally with the first housing structure  310 , and the second rear cover  390  may be configured integrally with the second housing structure  320 . 
     In an embodiment, the first rear cover  380 , the second rear cover  390 , the first housing structure  310 , and the second housing structure  320  may define a space in which various components (e.g., a printed circuit board and/or a battery) of the electronic device  101  may be disposed. In an embodiment, one or more components may be disposed and/or visually exposed on the rear surface of the electronic device  101 . For example, at least a portion of a sub-display  410  may be visually exposed through a first rear area  382  of the first rear cover  380 . In other embodiments, one or more components and/or sensors may be visually exposed through the second rear area  392  of the second rear cover  390 . The one or more components and/or sensors may include, but not be limited to, a proximity sensor and/or a rear camera. 
     Referring to  FIG.  3 B , the hinge cover  330  may be disposed between the first housing structure  310  and the second housing structure  320  to cover internal components (e.g., the hinge structure). For example, the hinge cover  330  may be covered by a portion of the first housing structure  310  and a portion of the second housing structure  320  and/or exposed to the outside depending on whether the electronic device  101  is in the unfolded state (e.g., flat state) or in the folded state. 
     For example, as shown in  FIG.  3 A , when the electronic device  101  is in the unfolded state, the hinge cover  330  may not be exposed by being covered by the first housing structure  310  and the second housing structure  320 . Alternatively or additionally, as shown in  FIG.  3 B , when the electronic device  101  is in the folded state (e.g., the fully folded state), the hinge cover  330  may be exposed to the outside between the first housing structure  310  and the second housing structure  320 . As an example, when the first housing structure  310  and the second housing structure  320  are in the intermediate state in which the first housing structure  310  and the second housing structure  320  are folded with a certain angle therebetween, the hinge cover  330  may be exposed to the outside between the first housing structure  310  and the second housing structure  320 . However, the area exposed in this case may be smaller than that in the fully folded state. In some embodiments, the hinge cover  330  may include a curved surface. 
     The display  200  may be disposed in a space defined by the foldable housing  300 . For example, the display  200  may be seated in the recess defined by the foldable housing  300 , and may constitute a large portion of the front surface of the electronic device  101 . 
     In some embodiments, the front surface of the electronic device  101  may include the display  200 , and a portion of the first housing structure  310  and a portion of the second housing structure  320 , which are adjacent to the display  200 . Alternatively or additionally, the rear surface of the electronic device  101  may include the first rear cover  380 , a portion of the first housing structure  310  adjacent to the first rear cover  380 , the second rear cover  390 , and a portion of the second housing structure  320  adjacent to the second rear cover  390 . 
     The display  200  may be a display in which at least a partial area is deformable into a planar surface or a curved surface. In an embodiment, the display  200  may include a folding area  203 , a first area  201  disposed on one side of the folding area  203  (e.g., the left side of the folding area  203  illustrated in  FIG.  3 A ), and a second area  202  disposed on the other side of the folding area  203  (e.g., the right side of the folding area  203  illustrated in  FIG.  3 A ). 
     The area division of the display  200  illustrated in  FIG.  3 A  is exemplary, and the display  200  may be divided into multiple areas (e.g., four or more areas, or two areas) depending on the structure or functions thereof. For example, as shown in  FIG.  3 A , the areas of the display  200  may be divided by the folding area  203  or the folding axis (the axis A) extending parallel to the Y (e.g., vertical) axis. However, in other embodiments, the display  200  may be divided into areas based on another folding area (e.g., a folding area parallel to the X (e.g., horizontal) axis) or another folding axis (e.g., a folding axis parallel to the X axis). 
     The first area  201  and the second area  202  may have generally symmetrical shapes about the folding area  203 . In some embodiments, the second area  202  may include a notch cut due to the presence of the sensor area  324 , but may have a shape symmetrical to the first area  201  in areas other than the sensor area. That is, the first area  201  and the second area  202  may include portions having mutually symmetrical shapes and portions having mutually asymmetrical shapes. 
     Hereinafter, the operations of the first housing structure  310  and the second housing structure  320  and respective areas of the display  200  according to the states of the electronic device  101  (e.g., the unfolded state (or flat state) and the folded state) are described. 
     According to an embodiment, when the electronic device  101  is in the unfolded state (flat state) (e.g.,  FIG.  3 A ), the first housing structure  310  and the second housing structure  320  may be disposed to form an angle of 180 degrees therebetween and to face the same direction. The surface of the first area  201  and the surface of the second area  202  of the display  200  may form 180 degrees relative to each other and may face the same direction (e.g., the front direction of the electronic device). The folding area  203  may form the same plane as the first area  201  and the second area  202 . 
     In an embodiment, when the electronic device  101  is in the folded state (e.g.,  FIG.  3 B ), the first housing structure  310  and the second housing structure  320  may be disposed to face each other. The surface of the first area  201  and the surface of the second area  202  of the display  200  may face each other while forming a narrow angle (e.g., an angle between 0 degrees and 10 degrees) relative to each other. At least a portion of the folding area  203  may be configured as a curved surface having a predetermined curvature. 
     According to an embodiment, when the electronic device  101  is in the intermediate state (e.g.,  FIG.  2 C ), the first housing structure  310  and the second housing structure  320  may be disposed with a certain angle therebetween. The surface of the first area  201  and the surface of the second area  202  of the display  200  may form an angle larger than that in the folded state and smaller than that in the unfolded state. At least a portion of the folding area  203  may have a curved surface having a predetermined curvature, and the curvature in the intermediate state may be smaller than that in the folded state. 
     Referring to  FIG.  3 C , in an embodiment, the electronic device  101  may include a display unit  220 , a bracket assembly  230 , a board unit  260 , a first housing structure  310 , a second housing structure  320 , a first rear cover  380 , and a second rear cover  390 . Herein, the display unit  220  may be referred to as a display module and/or a display assembly. 
     The display unit  220  may include a display  200  and at least one plate or layer  340  on which the display  200  is seated. In an embodiment, the plate  340  may be disposed between the display  200  and the bracket assembly  230 . The display  200  may be disposed on at least a portion of one surface (e.g., the top surface with reference to  FIG.  3 C ) of the plate  340 . The plate  340  may be formed in a shape corresponding to that of the display panel  200 . For example, a partial area of the plate  340  may be formed in a shape corresponding to the notch  205  in the display  200 . 
     The bracket assembly  230  may include a first bracket  241 , a second bracket  242 , a hinge structure disposed between the first bracket  241  and the second bracket  242 , a hinge cover  330  configured to cover the hinge structure when the hinge structure is viewed from the outside, and a wiring member  335  (e.g., a flexible printed circuit board (FPCB)) extending across the first and second brackets  241  and  242 . 
     In an embodiment, the bracket assembly  230  may be disposed between the plate  340  and the board unit  260 . For example, the first bracket  241  may be disposed between the first area  201  of the display  200  and a first board  261 . The second bracket  242  may be disposed between the second area  202  and the second board  262  of the display  200 . 
     In an embodiment, at least a portion of the wiring member  335  and at least a portion of the hinge structure may be disposed inside the bracket assembly  230 . The wiring member  335  may be disposed in a direction across the first bracket  241  and the second bracket  242  (e.g., the x-axis direction). The wiring member  335  may be disposed in a direction (e.g., the x-axis direction) perpendicular to the folding axis (e.g., the y axis or the folding axis A in  FIG.  3 A ) of the folding area  203  of the electronic device  101 . 
     As described above, the board unit  260  may include the first board  261  disposed on the first bracket  241  side and the second board  262  disposed on the second bracket  242  side. The first board  261  and the second board  262  may be disposed in a space defined by the bracket assembly  230 , the first housing structure  310 , the second housing structure  320 , the first rear cover  380 , and the second rear cover  390 . Components for implementing various functions of the electronic device  101  may be mounted on the first board  261  and the second board  262 . 
     The first housing structure  310  and the second housing structure  320  may be assembled to each other so as to be coupled to the opposite sides of the bracket assembly  230  in the state in which the display unit  220  is coupled to the bracket assembly  230 . As described below, the first housing structure  310  and the second housing structure  320  may be coupled to the bracket assembly  230  by sliding on the opposite sides of the bracket assembly  230 .

       FIG.  4 C  is an exploded perspective view illustrating an electronic device  400  according to various embodiments disclosed herein. The electronic device  400  of  FIG.  4 C  may include or may be similar in many respects to at least one of the electronic device  101  described above in reference to  FIGS.  3 A,  3 B,  3 C,  4 A, and  4 B , and may include additional features not mentioned above. 
     Referring to  FIG.  4 C , the electronic device  400  may include a first structure  401 , a second structure  402  (e.g., a housing), a display  403  (e.g., a flexible display), a guide member (e.g., a roller  451 ), a support sheet  463 , and/or an articulated hinge structure  413 . A portion of the display  403  (e.g., the second area A 2 ) may be accommodated inside the second structure  402  while being guided by the roller  451 . 
     According to various embodiments, the first structure  401  may include a first plate  411   a  (e.g., a slide plate), and a first bracket  411   b  and/or a second bracket  411   c , which are mounted on the first plate  411   a . The first structure  401 , for example, the first plate  411   a , the first bracket  411   b , and/or the second bracket  411   c  may be made of a metal material and/or a non-metal material (e.g., polymer). The first plate  411   a  may be mounted on the second structure  402  (e.g., a housing) to be linearly reciprocable in one direction (e.g., the direction indicated by arrow {circle around ( 1 )} in  FIG.  1   ) while being guided by the second structure  402 . 
     In an embodiment, the first bracket  411   b  may be coupled to the first plate  411   a  to define the first surface F 1  of the first structure  401  together with the first plate  411   a . The first area A 1  of the display  403  may be substantially mounted on the first surface F 1  to maintain a flat plate shape. The second bracket  411   c  may be coupled to the first plate  411   a  to define the second surface F 2  of the first structure  401  together with the first plate  411   a . According to an embodiment, the first bracket  411   b  and/or the second bracket  411   c  may be configured integrally with the first plate  411   a . This may be appropriately designed in consideration of the assembly structure or manufacturing process of a manufactured product. The first structure  401  or the first plate  411   a  may be coupled to the second structure  402  to be slidable relative to the second structure  402 . 
     According to various embodiments, the articulated hinge structure  413  may include a plurality of bars or rods  414  and may be connected to one end of the first structure  401 . For example, as the first structure  401  slides, the articulated hinge structure  413  may move relative to the second structure  402 , and in the closed state (e.g., the state illustrated in  FIG.  4 A ), the first structure  401  may be substantially accommodated inside the second structure  402 . In some embodiments, even in the closed state, a portion of the articulated hinge structure  413  may not be accommodated inside the second structure  402 . For example, even in the closed state, a portion of the articulated hinge structure  413  may be located to correspond to the roller  451  outside the second structure  402 . The plurality of rods  414  may linearly extend to be parallel to the rotation axis R of the roller  451 , and may be arranged in a direction perpendicular to the rotation axis R, for example, the direction in which the first structure  401  slides. 
     According to various embodiments, each rod  414  may turn around another adjacent rod  414  while maintaining the state parallel to the other adjacent rod  414 . Accordingly, as the first structure  401  slides, the plurality of bars  414  may be arranged in a form of a curved surface or a flat surface shape. For example, as the first structure  401  slides, the articulated hinge structure  413  may form a curved surface in a portion facing the roller  451 , and the articulated hinge structure  413  may form a flat surface in a portion not facing the roller  451 . In an embodiment, the second area A 2  of the display  403  may be mounted or supported on the articulated hinge structure  413 , and in the opened state (e.g., the state illustrated in  FIG.  4 B ), the second area A 2  of the display  103  may be exposed to the outside of the second structure  402  together with the first area A 1 . In the state in which the second area A 2  is exposed to the outside of the second structure  402 , the articulated hinge structure  413  may support or maintain the second area A 2  in the flat state by forming a substantially flat surface. 
     According to various embodiments, the second structure  402  (e.g., a housing) may include a second plate  421   a  (e.g., a rear case), a printed circuit board, a rear plate  421   b , a third plate ( 421   c ) (e.g., a front case), and a support member  421   d . The second plate  421   a  (e.g., the rear case) may be disposed to face away from the first surface F 1  of the first plate  411   a  and may substantially provide the external shape of the second structure  402  or the electronic device  101 . In an embodiment, the second structure  402  may include a first side wall  423   a  extending from the second plate  421   a , a second side wall  423   b  extending from the second plate  421   a  to be substantially perpendicular to the first side wall  423   a , and a third side wall  423   c  extending from the second plate  421   a  to be substantially perpendicular to the first side wall  423   a  and parallel to the second side wall  423   b . As shown in  FIG.  4 B , a structure in which the second side wall  423   b  and the third side wall  423   c  are manufactured as components separate from the second plate  421   a  and mounted on or assembled to the second plate  421   a  is exemplified. However, the second side wall  123   b  and the third side wall  123   c  may be manufactured integrally with the second plate  421   a . The second structure  402  may accommodate an antenna for proximity wireless communication, an antenna for wireless charging, or an antenna for magnetic secure transmission (MST) in a space that does not overlap the articulated hinge structure  413 . 
     According to various embodiments, the rear plate  421   b  may be coupled to the outer surface of the second plate  421   a , and the rear plate  221   b  may be manufactured integrally with the second plate  421   a  depending on an embodiment. In an embodiment, the second plate  421   a  may be made of a metal or polymer material, and the rear plate  421   b  may be made of a material such as metal, glass, a synthetic resin, or ceramic to provide a decoration effect in the external appearance of the electronic device  101 . According to an embodiment, the second plate  421   a  and/or the rear plate  421   b  may be made of a material that at least partially (e.g., in an auxiliary display area) transmits light. For example, in the state in which a portion of the display  403  (e.g., the second area A 2 ) is accommodated in the second structure  402 , the electronic device  101  may output visual information using a partial area of the display  403  accommodated inside the second structure  402 . The auxiliary display area may provide the visual information output from the area accommodated inside the second structure  402  to the outside of the second structure  402 . 
     According to various embodiments, the third plate  421   c  may be made of a metal or polymer material and may be coupled to the second plate  421   a  (e.g., the rear case), the first side wall  423   a , the second side wall  423   b , and/or the third side wall  423   c  to define an internal space of the second structure  402 . According to an embodiment, the third plate  421   c  may be referred to as a “front case”, and the first structure  401  (e.g., the first plate  411   a ) may slide in the state of substantially facing the third plate  421   c . In some embodiments, the first side wall  423   a  may be configured by a combination of a first side wall portion  423   a - 1  extending from the second plate  421   a  and a second side wall portion  423   a - 2  disposed at a side edge of the third plate  421   c . In other embodiments, the first side wall portion  423   a - 1  may be coupled to surround one side edge of the third plate  421   c  (e.g., the second side wall portion  423   a - 2 ), in which case, the first side wall portion  423   a - 1  itself may form the first side wall  423   a.    
     According to various embodiments, the support member  421   d  may be disposed in the space between the second plate  421   a  and the third plate  421   c  and may have a flat plate shape made of a metal or polymer material. The support member  421   d  may provide an electromagnetic shielding structure in the internal space of the second structure  402  or may improve mechanical rigidity of the second structure  402 . In an embodiment, when received inside the second structure  402 , the articulated hinge structure  413  and/or a partial area (e.g., the second area A 2 ) of the display  403  may be located in a space between the second plate  421   a  and the support member  421   d.    
     According to various embodiments, a printed circuit board may be disposed in the space between the third plate  421   c  and the support member  421   d . For example, the printed circuit board may be accommodated in a space separated, by the support member  421   d , from the space in which the articulated hinge structure  413  and/or a partial area of the display  403  may be accommodated inside the second structure  402 . On the printed circuit board, a processor, a memory, and/or an interface may be mounted. The processor may include, but not be limited to, at least one of, for example, a central processing unit, an application processor, a graphics processing unit, an image signal processor, a sensor hub processor, or a communication processor. 
     The memory may include, for example, a volatile memory or a nonvolatile memory. 
     The interface may include, but not be limited to, for example, a high-definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and/or an audio interface. The interface may electrically and/or physically connect, for example, the electronic device  101  to an external electronic device, and may include a USB connector, an SD card, an MMC connector, and/or an audio connector. 
     According to various embodiments, the display  403  may be a flexible display based on an organic light-emitting diode and may be at least partially deformed into a curved shape while being generally maintained in a flat shape. In an embodiment, the first area A 1  of the display  403  may be mounted on or attached to the first surface F 1  of the first structure  401  to maintain a substantially flat plate shape. The second area A 2  may extend from the first area A 1  and may be supported on or attached to the articulated hinge structure  413 . For example, the second area A 2  may extend along the sliding direction of the first structure  401 , may be accommodated inside the second structure  402  together with the articulated hinge structure  413 , and may be deformed in an at least partially curved shape according to the deformation of the articulated hinge structure  413 . 
     According to various embodiments, as the first structure  401  slides on the second structure  402 , the area of the display  403  exposed to the outside may vary. The electronic device  101  (e.g., a processor) may change the area of the display  403  that is activated based on the area of the display  403  exposed to the outside. For example, in the opened state or at a position intermediate between the closed state and the opened state, the electronic device  101  may activate the area exposed to the outside of the second structure  402  in the total area of the display  403 . In the closed state, the electronic device  101  may activate the first area A 1  of the display  403  and deactivate the second area A 2  of the display  403 . In the closed state, when there is no user input for a predetermined period of time (e.g., 30 seconds, 2 minutes, and the like), the electronic device  101  may deactivate the entire area of the display  403 . In some embodiments, in the state in which the entire area of the display  403  is deactivated, the electronic device  101  may provide visual information through an auxiliary display area (e.g., a portion of the second plate  421   a  and/or the rear plate  421   b  made of a material that transmits light) by activating a partial area of the display  403  as needed (e.g., providing a notification or a missed call/message arrival notification according to a user configuration). 
     According to various embodiments, in the opened state (e.g., the state illustrated in  FIG.  4 B ), substantially the entire area (e.g., the first area A 1  and the second area A 2 ) of the display  403  may be exposed to the outside, and the first area A 1  and the second area A 2  may be disposed to define a plane. In an embodiment, even in the opened state, a portion (e.g., one end) of the second area A 2  may be located to correspond to the roller  451 , and the portion corresponding to the roller  451  in the second area A 2  may be maintained in a curved shape. For example, in various embodiments, even if it is stated that “in the opened state, the second area A 2  is disposed to define a plane”, a portion of the second area A 2  may be maintained in a curved shape. Similarly, although it is stated that “in the closed state, the articulated hinge structure  413  and/or the second area A 2  are accommodated in the second structure  402 ”, a portion of the articulated hinge structure  413  and/or the second area A 2  may be located outside the second structure  402 . 
     According to various embodiments, a guide member (e.g., the roller  451 ) may be rotatably mounted on the second structure  402  at a position adjacent to one side edge of the second structure  402  (e.g., the second plate  421   a ). For example, the roller  451  may be disposed adjacent to the edge of the second plate  421   a  parallel to the first side wall  423   a  (e.g., the portion IE). Another side wall may extend from an edge of the second plate  421   a  adjacent to the roller  451 , and the side wall adjacent to the roller  451  may be substantially parallel to the first side wall  423   a . As described above, the side wall of the second structure  402  adjacent to the roller  451  may be made of a material that transmits light, and a portion of the second area A 2  may provide visual information through a portion of the second structure  402  in the state of being accommodated in the second structure  402 . 
     According to various embodiments, one end of the roller  451  may be rotatably coupled to the second side wall  423   b , and the other end may be rotatably coupled to the third side wall  423   c . For example, the roller  451  may be mounted on the second structure  402  to be rotatable about a rotation axis R perpendicular to the slide direction of the first structure  401  (e.g., the direction indicated by arrow {circle around ( 1 )} in  FIG.  1    or  FIG.  2   ). The rotation axis R may be disposed to be substantially parallel to the first side wall  423   a , and may be located, for example, at one side edge of the second plate  421   a  far from the first side wall  423   a . In some embodiments, the gap provided between the outer circumferential surface of the roller  451  and the inner surface of the edge of the second plate  421   a  may form an inlet through which the articulated hinge structure  413  or the display  403  enters the inside of the second structure  402 . 
     According to various embodiments, when the display  403  is deformed into a curved shape, the roller  451  may suppress excessive deformation of the display  403  by maintaining the radius of curvature of the display  403  to a certain degree. Excessive deformation may refer to the display  403  being deformed to have an excessively small radius of curvature to the extent that pixels or signal wires included in the display  403  are damaged. For example, the display  403  may be moved or deformed while being guided by the roller  451  and may be protected from damage due to excessive deformation. In some embodiments, the roller  451  may rotate while the articulated hinge structure  413  or the display  403  is inserted into or extracted from the second structure  402 . For example, by suppressing rubbing between the articulated hinge structure  413  (or the display  403 ) and the second structure  402 , the articulated hinge structure  413  (or the display  403 ) may smoothly perform the insertion/extraction operation of the second structure  402 . 
     According to various embodiments, the support sheet  463  may be made of a flexible and/or elastic material, for example, a material including an elastic body such as silicone or rubber, may be mounted on or attached to the roller  451 , and may be selectively wound around the roller  451  as the roller  451  rotates. As shown in  FIG.  4 C , a plurality of (e.g., four) support sheets  463  may be arranged along the direction of the rotation axis R of the roller  451 . For example, the plurality of support sheets  463  may be mounted on the roller  451  such that adjacent support sheets  463  are spaced apart from each other by a predetermined interval, and may extend in a direction perpendicular to the rotation axis R. In another embodiment, one support sheet may be mounted on or attached to roller  451 . For example, one support sheet may have a size and shape corresponding to the area in which the support sheets  463  are disposed and the areas between the support sheets  463  in  FIG.  3   . In this way, the number, size, or shape of the support sheets  463  may be appropriately changed depending on an actually manufactured product. In some embodiments, the support sheet  463  may be rolled on the outer circumferential surface of the roller  451  as the roller  451  rotates or may be spread out from the roller  451  in a flat plate shape from the space between the display  403  and the third plate  421   c . In another embodiment, the support sheet  463  may be referred to as a “support belt”, an “auxiliary belt”, a “support film”, or an “auxiliary film”. 
     According to various embodiments, an end of the support sheet  463  may be connected to the first structure  401  (e.g., the first plate  411   a  (e.g., a slide plate)), and the support sheet  463  may be rolled on the roller  451  in the closed state (e.g., the state illustrated in  FIG.  4 A ). Accordingly, when the first plate  411   a  moves to the opened state (e.g., the state illustrated in  FIG.  4 B ), the support sheet  463  may be gradually located between the second structure  402  (e.g., the third plate  421   c ) and the display  403  (e.g., the second area A 2 ) or between the second structure  402  (e.g., the third plate  421   c ) and the articulated hinge structure  413 . For example, at least a portion of the support sheet  463  may be located to face the articulated hinge structure  413 , and may be selectively wound around the roller  451  according to the sliding movement of the first plate  411   a . The support sheet  463  may be generally disposed to be in contact with the articulated hinge structure  413 , but a portion rolled on the roller  451  may be substantially separated from the articulated hinge structure  413 . 
     According to various embodiments, an arrangement gap between the surface of the display  403  and the inner surface of the edge of the second plate  421   a  may vary depending on the extent to which the support sheet  463  is wound around the roller  451 . The smaller the arrangement gap, the easier it may be to prevent introduction of foreign matter. However, when the arrangement gap is excessively small, the display  403  may come into contact with or rub against the second plate  421   a . When direct contact or rubbing occurs, the surface of the display  403  may be damaged or the sliding operation of the first structure  401  may be hindered. 
     According to various embodiments, in the closed state, since the support sheet  463  is wound around the roller  451 , it may be possible to reduce the gap between the surface of the display  403  and the inner surface of the edge of the second plate  421   a  while maintaining the state in which the surface of the display  403  is not in contact with the second plate  421   a . For example, by reducing the arrangement gap in the closed state, it may be possible to block the introduction of external foreign matter into the inside of the second structure  402 . In an embodiment, as the first structure  401  (e.g., the first plate  411   a  or the slide plate) gradually moves to the opened state, the support sheet  463  may move away from the roller  451  to gradually move to the space between the second structure  402  (e.g., the second plate  421   a  or the third plate  421   c ) and the articulated hinge structure  413 . For example, as the first structure  401  moves to the opened state, the arrangement gap gradually increases so that it may be possible to suppress direct rubbing or contact between the display  403  and another structure (e.g., the second plate  421   a ) and to prevent the surface of the display  403  from being damaged due to the rubbing or contact. In some embodiments, the thickness of the support sheet  463  may gradually increase from one end (e.g., the portion fixed to the roller  451 ) toward the other end (e.g., the portion fixed to the first plate  411   a ). By using the thickness profile of the support sheet  463 , it may be possible to adjust the arrangement gap in the closed state and the opened state. 
     According to various embodiments, the electronic device  101  may include at least one elastic member made of a low-density elastic body, such as a sponge, or a brush. For example, the electronic device  101  may include a first elastic member mounted at one end of the display  403 , and may further include a second elastic member mounted at the inner surface of an edge of the second plate  421   a  in some embodiments. The first elastic member may be substantially disposed in the internal space of the second structure  402 , and in the opened state (e.g., the state illustrated in  FIG.  4 B ), the first elastic member may be located to correspond to the edge of the second plate  421   a . In an embodiment, the first elastic member may move in the internal space of the second structure  402  according to the sliding movement of the first structure  401 . When the first structure  401  moves from the closed state to the opened state, the first elastic member may move toward the edge of the second plate  421   a . When the first structure  401  reaches the opened state, the first elastic member may come into contact with the inner surface of the edge of the second plate  421   a . For example, in the opened state, the first elastic member may seal the gap between the inner surface of the edge of the second plate  421   a  and the surface of the display  403 . In other embodiments, when moving from the closed state to the opened state, the first elastic member may move while coming into contact with the second plate  421   a  (e.g., slide contact). For example, when foreign matter is introduced into the gap between the second area A 2  and the second plate  421   a  in the closed state, the first elastic member may discharge the foreign matter to the outside of the second structure  402  while moving to the opened state. 
     According to various embodiments, the second elastic member may be attached to the inner surface at the edge of the second plate  421   a  and may be disposed to substantially face the inner surface of the display  403 . In the closed state, the gap (e.g., the arrangement gap) between the surface of the display  403  and the inner surface of the edge of the second plate  421   a  may be substantially determined by the second elastic member. According to an embodiment, in the closed state, the second elastic member may substantially seal the arrangement gap by coming into contact with the surface of the display  403 . According to an embodiment, the second elastic member may be made of a low-density elastic body, such as a sponge, or a brush, not to damage the surface of the display  403  even if the second elastic member comes into direct contact with the display  403 . In other embodiments, the arrangement gap may increase as the first structure  401  gradually moves to the opened state. For example, the second area A 2  of the display  403  may be gradually exposed to the outside of the second structure  402  without substantially coming into contact with or rubbing against the second elastic member. When the first structure  401  reaches the opened state, the first elastic member may come into contact with the second elastic member. For example, in the opened state, the first elastic member and the second elastic member may block the inflow of foreign matter by sealing the arrangement gap. 
     According to various embodiments, the electronic device  101  may further include guide rails  455  and/or actuating members  457 . The guide rails  455  may be mounted on the second structure  402  (e.g., the third plate  421   c ) to guide the sliding movement of the first structure  401  (e.g., the first plate  411   a  or slide plate). The actuating members  457  may include a spring or a spring module that provides an elastic force in a direction to move opposite ends thereof away from each other. One end of the actuating members  457  may be pivotably supported by the second structure  402 , and the other end may be pivotably supported by the first structure  401 . When the first structure  401  slides, the opposite ends of the actuating members  457  may be located closest to each other at any one point between the closed state and the opened state (hereinafter, referred to as the “closest point”). For example, in the section between the closest point and the closed state, the actuating members  457  may provide an elastic force to the first structure  401  in a direction to move the first structure  401  toward the closed state and in the section between the closest point and the opened state, the actuating members  457  may provide an elastic force to the first structure  401  in a direction to move the first structure  401  toward the opened state.

For example, the predetermined angle range may include a first angle range (e.g., 180 degrees or more), a predetermined second angle range (e.g., greater than 0 degrees and less than 180 degrees), and a predetermined third angle range (e.g., 0 degrees). Examples of predetermined angle ranges are examples for helping understanding, and the disclosure is not limited thereto. According to various embodiments, the predetermined angle ranges may be configured and/or changed by a designer and/or a user. Alternatively or additionally, the folding state may indicate an angle change pattern, such as an increasing trend or a decreasing trend of the folding angle. 
     According to various embodiments, a state manager  521  may communicate with one or more other components (e.g., a folding event converter  525 , a grab event manager  527 , a context manager  526 , or the like) and collect information related to the states of the electronic device, and may provide the collected information to one or more other components (e.g., a state memory module  524 , an application  501 , a window manager  510 , or the like). The information related to the states of the electronic device may include at least one of folding state-related information, holding-related information, hovering input-related information, and a user&#39;s touch input-related information. According to various embodiments, a state memory module  524  may store information related to the states of the electronic device. 
     According to various embodiments, a folding event dispatcher  520  (or an event handler) may transmit related information, which is related to the folding state of the electronic device, to the window manager  510  or the application  501 . 
     According to various embodiments, a notification/message manager  541  may provide a user with events (e.g., an arrival message, an appointment, a proximity notification, and the like). According to various embodiments, an event logger  542  may record the events and display the events in time order. According to various embodiments, a telephony module  543  may manage a voice/video call function of the electronic device. A timer  544  may provide a timer function. According to various embodiments, a location manager  545  may manage, for example, position information of the electronic device. According to various embodiments, a power manager  546  may be interlocked with, for example, a power controller  550  so as to manage the capacity or power of a battery and to provide power information required for the operation of the electronic device. 
     According to various embodiments, a system event receiver  523  may receive events from the notification/message manager  541 , the event logger  542 , the telephony module  543 , the timer  544 , or the power manager  546 , and may transmit the events to a context manager  526 . According to various embodiments, an input handler  528  may receive inputs from a TSP  536 , a mouse  537 , and/or a key  538 , and may forward the inputs to the context manager  526 . According to various embodiments, the context manager  526  may manage system services based on an input, a system event, a folding state, and the like. 
     According to various embodiments, the grab event manager  527  may receive information (e.g., a touch input area and/or a position) related to a holding state of the electronic device from a touch sensor  535 , and may transmit the information to the state manager  521 . 
     According to various embodiments, a display controller  551  may control turning on/off of a screen. A frame buffer  552  may store pixel values or pixel color values to be output to a display.

     Hereinafter, another example of software modules included in the electronic device  101  according to various embodiments is described. 
       FIG.  6    is a view for describing examples of software modules included in an electronic device  101  according to various embodiments. Hereinafter, components for changing the execution screen of an application of the electronic device  101  are described with reference to  FIG.  6   . 
     According to various embodiments, the electronic device  101  may include a hardware layer (HW) including a sensor controller  611  and a display panel  612 , a kernel layer (Kernel) including a sensor driver  621  and a DDI controller  623 , a library layer (HAL) including an event hub  631  and a surface flinger  633 , a frame work layer (Framework) including a sensor manager  636 , a window manager  636 , a view system  638 , an activity manager  639 , and a state control manager  637 , and an application layer (Application) including first application  641 , second application  642 , and third application  643 , and a dynamic task manager (DTM)  644 . In some embodiments, the memory  130  may store the kernel layer, the library layer, the framework layer, and the application layer in the form of instructions so as to allow the processor to execute the operations of corresponding components when the layers are executed. 
     Hereinafter, the hardware layer (HW) and the kernel layer (Kernel) are described. 
     According to various embodiments, the sensor controller  611  may detect various states of the electronic device  101 . A redundant description related to the sensor controller  611  is omitted. According to various embodiments, the sensor driver  621  may cause the sensor controller  611  to be driven. 
     According to various embodiments, the display panel  612  may include an application execution screen. A redundant description related to the display panel  612  is omitted. According to various embodiments, the display controller (DDI controller)  604  may correspond to a display drive circuit DDI. 
     Without being limited to the above description, the hardware layer (HW) and the kernel layer (Kernel) may be implemented in the same manner as a well-known technology, and thus other redundant descriptions are omitted. 
     Hereinafter, the library layer (HAL) is described. 
     According to various embodiments, the event hub  605  may allow collected events and data to be processed. For example, the event hub  631  may transmit the collected events and data from the sensor module  611  to the framework layer such that a service corresponding thereto can be provided. 
     According to various embodiments, the surface flinger  606  may synthesize multiple layers. The surface flinger  633  may provide data representing the multiple synthesized layers to the display controller  604 . 
     Since the library layer (HAL) may be implemented in the same manner as well-known technology without being limited to the above description, other redundant descriptions are omitted. 
     Hereinafter, the framework layer (Framework) is described. 
     According to various embodiments, the sensor manager  607  may manage the events and data acquired by the sensor module  611 . 
     According to various embodiments, the window manager  608  may perform operations such that the execution screen of an application is changed according to a change in angle. 
     For example, the window manager  636  may manage at least one predetermined application (or manage a list) that supports execution screen change. The window manager may identify at least one application that supports execution screen change among a plurality of applications, which are currently being executed, based on the list, and may control the at least one application to change the execution screen. For example, the window manager  636  may transmit an unfolding/folding event to the at least one application that supports execution screen change. The at least one application may provide an execution screen corresponding to the acquired unfolding/folding event, and the graphic composer  669  may provide data based on the received execution screen to the display driver. The wording “the window manager  636  or another manager controls an application” may include providing information on an event acquired by the window manager  636  or another manager to the application. 
     For example, the window manager  636  (e.g., the state control manager  637 ) may identify whether or not the state of the electronic device  101  is changed (e.g., changed from the opened mode to the half-folded mode) based on the data acquired with the sensor controller  611 . In other words, the state control manager  637  may manage the current state of the electronic device  101 . 
     Alternatively or additionally, for example, when a change in the state of the electronic device  101  (e.g., the change from the opened mode to the half-folded mode) is identified through the sensor module  611 , the window manager  636  may transmit information corresponding to the changed state of the electronic device  101  to an application. For another example, when the change in the state of the electronic device  101  is identified, the window manager  608  may transmit information on a display area corresponding to the changed state of the electronic device  101  to a predetermined application that supports the change of an execution screen, among applications  612 , which are being executed. 
     According to various embodiments, the view system  610  may be a program for drawing at least one layer based on the resolution of the display panel  612 . In some embodiments, an application may draw at least one layer based on the resolution of a second display area of the display panel  612  by using the view system  638 . The view may manage various execution screens displayed by the application and graphic elements included in the execution screens. 
     According to various embodiments, the activity manager  639  may acquire and manage various kinds of information related to the state of execution of an application (e.g., a foreground mode or a background mode). 
     Since the framework may be implemented in the same manner as well-known technology without being limited to the above description, other redundant descriptions are omitted. 
     Hereinafter, the application layer (Apps) is described. 
     According to various embodiments, the application layer may include various types of applications installed in the electronic device and a dynamic task manager (DTM). 
     As described above, the various types of applications  641 ,  642 , and  643  may include, but not be limited to, for example, a home application, a dialer application, an SMS/MMS application, an IM application, a browser application, a camera application, an alarm application, a contact application, a voice dial application, an e-mail application, a calendar application, a media player application, an album application, a watch application, a health care (e.g., measurement of a quantity of motion, or blood sugar) application, or an environmental information (e.g., atmospheric pressure, humidity, or temperature information) providing application. 
     The dynamic task manager  644  is a type of recent application, and may provide information on applications executed in a background mode to the electronic device. The foreground mode refers to the state of an application executed in a process in a state that is controllable by a user, and the background mode refers to the state of an application that is executed in a process other than the foreground mode (e.g., a process in a state that is not controllable by the user). The dynamic task manager  644  may receive information on the folding state of the electronic device from the state control manager, and switch the execution screen based on the received information on the folding state. The execution screen switching may mean changing a visual attribute (e.g., shape, size, and/or color) of information (e.g., objects, and/or contents) included in the execution screen, and adjusting a position. The execution screen switching operation is described in further detail below. 
     Alternatively or additionally, the dynamic task manager  644  may perform control on an application, which is being executed in a background mode, so that a specific application is executed in the foreground mode. For example, when an object (e.g., an icon and/or a thumbnail) for one application displayed on the execution screen of the dynamic task manager  644  is selected, the dynamic task manager  644  may control the one application in the foreground mode. Hereinafter, the dynamic task manager  644  is described as a recent application, and the operations of the electronic device based on the recent application are described in further detail below. 
     Hereinafter, examples of the operations of the electronic device  101  according to various embodiments are described. 
     According to various embodiments, when the folding angle is changed, the electronic device  101  may display a plurality of objects included in the execution screen of the recent application (e.g., the DTM in  FIG.  6   ) in a first area  831  (see  FIG.  8   ), and may configure a plurality of touch areas for selecting the plurality of objects in a second area different from the first area  831 . When a user input is identified on the plurality of touch areas, the electronic device  101  may select an application corresponding to a touch area selected by the user input. The electronic device  101  may display the execution screen of the application by executing the selected application in the foreground mode. 
       FIG.  7    is a flowchart  700  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  7    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  7    may be performed. Hereinafter, the operations of  FIG.  7    are described with reference to  FIGS.  8  through  11 B . 
       FIG.  8    is a view for describing examples of operations of switching and displaying the execution screen of a recent application of an electronic device  101  according to various embodiments to another execution screen, and displaying the execution screen of an application selected based on the recent application.  FIG.  9    is a view for describing operations of a processor and applications of an electronic device  101  according to various embodiments.  FIG.  10    is a view for describing an example of an operation of transforming an object (e.g., a thumbnail) of an electronic device  101  according to various embodiments.  FIG.  11 A  is a view for describing an example of an operation of switching the execution screen of a recent application of an electronic device  101  according to various embodiments.  FIG.  11 B  is a view for describing another example of an operation of switching the execution screen of a recent application of an electronic device  101  according to various embodiments. 
     According to various embodiments, the electronic device  101  may display the execution screen of a first application including at least one first object in operation  701 . For example, as illustrated in  801  to  802  of  FIG.  8   , in the state in which the angle between housings (the first housing  835  and the second housing  836 ) is a first angle (e.g., 180 degrees), the electronic device  101  may detect an event for executing a first application (e.g., the DTM of  FIG.  6    or a recent application) for providing information on an application, which is being executed in the background mode in the state, and may display the execution screen  820  of the first application (e.g., the recent application) based on event detection. For example, the event may include a user input for selecting an icon and/or an object (e.g., an object  812  displayed on a navigation bar as illustrated in  801  in  FIG.  8   ) for executing the first application. For example, while displaying a specific screen (e.g., a home screen  811 ), the electronic device  101  may display an object  812  for executing a recent application at the lower end of a specific screen (e.g., the object  812  on the navigation bar), and may display the execution screen  820  of the recent application when the object  812  is selected. In addition, the event may include that an angle (or a folding angle) between the housings  835  and  836  is changed and included within a predetermined range. For example, when the folding angle is changed and included within a predetermined range, the electronic device  101  may perform operation  703  (e.g., an operation of transforming and displaying an object) together while displaying the execution screen of the first application (e.g., the recent application) together. At this time, the executed first application  910  may be switched to the foreground mode as illustrated in  FIG.  9   , and a third application  930  that has been originally executed in the foreground mode (e.g., an application for display a home screen) may be switched to the background mode. Hereinafter, the operation of the first application (e.g., a receive application) is described. For convenience of description, the first application is described by taking the recent application as an example, but is not limited thereto, and the electronic device  101  may display the execution screens of other types of applications (e.g., gallery, camera, and game applications). For example, as described below with reference to  FIGS.  38  to  39   , the electronic device  101  may perform the following operations with respect to contents included in the execution screens of various types of applications. There are no restrictions on commands for executing a recent application or other types of applications. 
     According to various embodiments, the recent application may acquire information about applications which are being executed in the background mode among a plurality of applications, on the electronic device  101 , and may display at least one first object based on the acquired information. The foreground mode may refer to the state of an application that is executed in a process in a state that is controllable by a user, and the background mode may refer the state of an application that is executed in a process other than the foreground mode (e.g., a process in a state that is not controllable by the user). For example, as illustrated in  801  of  FIG.  8   , a partial area of the execution screen  820  of the recent application may include, as the at least one first object, icons  821 ,  822 , and  823  representing applications which are being executed in the background mode and thumbnails  824 ,  825 , and  826 . The recent application may acquire information about the screens of applications which are being executed in the background mode (e.g., information about views, and information about a screen displayed while being executed in the foreground mode), and may display thumbnails  824 ,  825 , and  826  based on the acquired information. In addition, the recent application may acquire information about icon images corresponding to the pre-stored applications which are being executed in the background mode, and may display the icons  821 ,  822 , and  823  (e.g., display the icons  821 ,  822 , and  823  to overlap partial areas of the thumbnails  824 ,  825 , and  826 ) based on the acquired information. For example, the recent application may display various kinds of information in another partial area of the execution screen  820 . As another example, the another partial area of the execution screen  820  of the recent application may include icons for executing recommended applications. Alternatively or additionally, an area other than the areas in which the above-described various kinds of information of the execution screen  820  of the recent application is displayed (e.g., the partial areas and the another partial area) may display a predetermined color (e.g., a color for background processing) or may be blurred. The execution screen  820  of the recent application illustrated in  801  of  FIG.  8    is merely an example in the form of a carousel, and may be implemented in various forms (e.g., a stack, a list, a grid, a carousel, a slim list, and a vertical stack). The various forms are known forms, and descriptions related thereto are omitted. 
     According to various embodiments, when the folding angle is identified as being changed in operation  702 , in operation  703 , the electronic device  101  may display at least one second object different from the at least one first object (e.g., the icons  821 ,  822 , and  823 , and the thumbnails  824 ,  825 , and  826  included in the execution screen  820  of the first application) in the first area  831  of the display. For example, as illustrated in  803  of  FIG.  8   , as the relative positions of the housings (e.g., the first housing  835  and the second housing  836 ) of the electronic device  101  are changed according to the pivoting of the hinge (or the housings are rotated about the hinge), the angle (or the folding angle) between the housings (e.g., first housing  835  and second housing  836 ) may be changed from a first angle (e.g., 180 degrees) to a second angle (e.g., 130 degrees). The processor  120  (e.g., the state control manager  635  of the window manager  636 ) of the electronic device  101  may acquire values detected by the sensors as the angle between the housings is changed, and may identify the folding state based on the values. The folding state may include at least one of whether the housings are in contact, a folding angle, or an angle range corresponding to the folding angle, as described above with reference to  FIG.  5   . As illustrated in  FIG.  9   , the processor (e.g., the state control manager  635  of the window manager  636 ) may transmit a value for notifying that the folding angle corresponds to (e.g., is included in) a second angle range (e.g., 120 to 160 degrees) to the recent application (e.g., the first application or the DTM)  910 . The recent application  910  may identify that the folding angle corresponds to the second angle range (e.g., 120 degrees to 160 degrees) (operation  911 ), and may perform an operation of changing the execution screen (operation  913 ). The second angle range serving as a reference for starting the change of the execution screen may be a range preconfigured in the electronic device  101  and may be adjustable by the user or the electronic device  101 . As illustrated in  803  of  FIG.  8   , the changed execution screen may include, in the first area  831 , at least one second object (e.g., the icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ) different from the at least one previously displayed first object (e.g., the icons  821 ,  822 , and  823  and the thumbnails  824 ,  825 , and  826 ) previously displayed first object (e.g., icons  821 ,  822 ,  823  and thumbnails  824 ,  825 ,  826 ). The wording “different from” may refer to the visual attributes (e.g., at least one of shape, size, or color) of the first object and the second object being different from each other, but the contents (e.g., the images of icons or the images of thumbnails), which are included in the first object and the second object, respectively, correspond to (or are equal to) each other. In an execution screen change, the first area  831  in which the at least one second object is displayed may be an area corresponding to a hinge to which the housings are connected or an area in which a flexible display is bent as the folding angle is changed. Hereinafter, the at least one second object is further described. 
     First, the visual attributes of the at least one second object (e.g., the icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ) are further described. 
     According to various embodiments, the at least one second object (e.g., the icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ) displayed in the first area  831  may have a visual attribute different from the visual attribute of the at least one first object (e.g.,  821 ,  822 ,  823 ,  824 ,  825 , and  826 ) displayed when the angle corresponds to the first angle range. The visual attribute may include at least one of a shape or a size. For example, as illustrated in  FIG.  10   , the size of the second object (e.g.,  1002  or  1003 ) (e.g., a thumbnail) may be smaller than the size of the first object  1001 . For example, as illustrated in  1002  of  FIG.  10   , the electronic device  101  may reduce (e.g., re-sizes) the size of the first object (e.g., a thumbnail) to correspond to the size of a portion of the first area  831 ), and may display the second object (e.g., a thumbnail) in the first area  831 . In addition, for example, as illustrated in  1003  of  FIG.  10   , the electronic device  101  may select (e.g., crop) only a partial area of the first object (e.g., a thumbnail) by a size corresponding to the size of a portion of the first area  831 , and may display the cropped are as the second object (e.g., a thumbnail). The electronic device  101  may select (e.g., crop) a main portion in which a specific content in the first object such that an application may be easily identified by the user based on the second object. The specific content may be a content including an application name of a background application or a representative color. 
     According to various embodiments, one or more second objects (e.g., icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ) displayed in the first area  831  may have different visual attributes, respectively. For example, the size of one object (e.g., an icon or a thumbnail) among the second objects displayed in the first area  831  may be different from the size of another object (e.g., an icon or a thumbnail). For example, the electronic device  101  may configure the sizes of the second objects to be different from each other based on the positions of the second objects. The electronic device  101  may display the second objects such that the sizes of the second objects are to be gradually smaller from the uppermost stage (e.g., sequentially from the uppermost column) downward. In addition, the electronic device  101  may display the second objects such that the sizes of the second objects are gradually smaller from the central area toward the peripheral area. As another example, the electronic device  101  may configure the sizes of the objects to be larger in the order of priorities of the applications corresponding to the second objects from the highest priority. For example, the order of priorities may be configured such that an application which has been most recently controlled by a user interaction (or the highest activity stack) and is being executed in a background mode has the highest priority. For example, the order of priorities may be configured such that the application most closely related to (e.g., most frequently used together with) an application that was being executed in the foreground mode prior to the recent application has the highest priority. 
     Hereinafter, the display positions of the at least one second object (e.g., the icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ) are further described. 
     According to various embodiments, the electronic device  101  may display the execution screen of a first application (e.g., a recent application) in which the at least one second object (e.g., the icons  851 ,  852 , and  853  and the thumbnails  854 ,  855 , and  856 ) are arranged in columns and rows in the first area  831  based on the angle between the housings  835  and  836  corresponding to the second angle range. For example, the electronic device  101  may arrange different types of objects (e.g., icons and thumbnails) related to applications in sub-areas  1131  and  1132  included in the first area  831 . For example, as illustrated in  803  in  FIG.  8   , the first area  831  may include a first sub-area  1131  associated with the first housing  835  and a second sub-area  1132  associated with the second housing  836 . The first sub-area  1131  may be a display area corresponding to the first housing  835  in the first area  831 , and the second sub-area  1132  may be a display area corresponding to the second housing  836  in the first area  831 . The execution screen may include one icon and one thumbnail corresponding to one application among a plurality of applications executed in the background mode in a specific row of the first area  831 , and the one icon may be located in a column corresponding to the first sub-area  1131 , and the one thumbnail may be disposed in a column corresponding to the second sub-area  1132 . Icons and thumbnails for the remaining applications may also be arranged in rows and columns of the first area  831  as described above. 
     According to various embodiments, the electronic device  101  may arrange the second objects (e.g., the icons  851 ,  852 , and  853  and the thumbnails  854 ,  855 , and  856 ) displayed in the first area  831  based on information about applications executed in the background mode corresponding to the second objects (e.g., the icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ). For example, the electronic device  101  may determine a display order of the objects based on information on the order of priorities of applications executed in the background mode, and may select the second objects (e.g., the icons  851 ,  852 , and  853  and the thumbnails  854 ,  855 , and  856 ) in the determined order of priorities. The electronic device  101  may arrange objects (e.g., icons and/or thumbnails) corresponding to applications in the order of priorities from the highest priority, downward from the uppermost position (e.g., sequentially from the uppermost column). Alternatively or additionally, the electronic device  101  may arrange the second objects from the center area (or the middle of the display) of the first area  831  to the peripheral area of the first area  831  in the order of priorities from the highest priority. In addition, the electronic device  101  may display a predetermined number of second objects in the first area  831 , and may display the remaining objects when the first area  831  is scrolled. In this case, the electronic device  101  may select the predetermined number of second objects in the order of priorities from the highest priority and display the second objects in the first area  831 . 
     Hereinafter, examples of the operation of changing the execution screen based on a fact that the electronic device  101  corresponds to a second angle range are further described. 
     For example, based on the folding angle corresponding to the second angle range (e.g., the folding angle being included in the second angle range), the electronic device  101  may display the execution screen of a first application of at least one second object (e.g., the icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ) in a layout (e.g., the first area  831 ) stored in advance to correspond to the second angle range. For example, the electronic device  101  may store a layout of execution screens of the first application configured to be displayed corresponding to a plurality of predetermined angle ranges, respectively. As an example, the electronic device  101  stores the execution screens of the layout illustrated in  802  of  FIG.  8    in response to the folding angle being in the first angle range (e.g., 180 degrees), and may store the execution screens of a layout in which a plurality of objects are arranged in the first area  831  in response to the folding angle being in the second angle range (e.g., 120 degrees to 160 degrees). The electronic device  101  may identify an execution screen of the layout corresponding to the second angle range among execution screens of a plurality of layouts based on the folding angle corresponding to the second angle range, and may display the identified execution screen. The electronic device  101  may switch the execution screen corresponding to the first angle range to an execution screen corresponding to the identified second angle range, and display the execution screen corresponding to the identified second angle range. In this case, the electronic device  101  may provide a dynamic switching effect while switching the execution screen to another execution screen and displaying the another screen. For example, as illustrated in  1101  of  FIG.  11 A , the folding angle may be changed while the electronic device  101  displays the execution screen of the layout corresponding to the first angle range and may reach the second angle range. After the folding angle reaches the second angle range, the electronic device  101  may display a blurred screen (or a screen configured to be displayed by a specific color, or a screen including an animation effect) as illustrated in  1102  and  1103  of  FIG.  11 A , and thereafter, the electronic device  101  may display an execution screen corresponding to the second angle range in which icons  851 ,  852 , and  853  are arranged in the first sub-area  1131  and the thumbnails  854 ,  855  and  856  are arranged in the second sub-area  1132 . 
     In addition, for example, based on the folding angle corresponding to the second angle range, the electronic device  101  may dynamically transform and display a plurality of objects included in the execution screen of the first application. For example, the electronic device  101  may adjust and display the shapes and/or positions of the plurality of objects. For example, the electronic device  101  may adjust the sizes of (e.g., resize) the icons  821 ,  822 , and  823  as illustrated in  1113  of  FIG.  11 B  and may arrange the icons  851 ,  852 , and  853  having the adjusted sizes in the first sub-area  1131 . In addition, the electronic device  101  may adjust the sizes of (e.g., resize) the thumbnails  824 ,  825 , and  826  and may display the thumbnails  854 ,  855 , and  856  having the adjusted size in the second sub-area  1132 . Without being limited thereto, the transformed icons  851 ,  852 , and  853  may be arranged in the second sub-area  1132 , and the transformed thumbnails  854 ,  855 , and  856  may be displayed in the first sub-area  1131 . As illustrated in  1112  and  1113  of  FIG.  11 B , the electronic device  101  may gradually transform each object (e.g., changing the position and size of each object), and may display each resultant object in the first area  831 . 
     Although it has been described above that both the thumbnails and the icons are displayed in the first area  831 , the disclosure is not limited to thereto, and the electronic device  101  may display one of thumbnails or icons in the first area  831  based on the angle corresponding to the second angle range. 
     According to various embodiments, the electronic device  101  may receive a selection of at least one of at least one second object in operation  704 . For example, the electronic device  101  may receive a selection of an object (an icon or a thumbnail)  834  disposed in a specific row among the objects (e.g., the icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ) displayed in the first area  831 , as illustrated in  803  of  FIG.  8   . For example, the electronic device  101  may receive a selection of a specific object through a plurality of touch areas for selecting a plurality of objects configured in the remaining second area different from the first area  831 . An operation of configuring a plurality of touch areas for selection of objects of the electronic device  101  in the second area and an operation of receiving a selection of an object through a touch area are described with reference to  FIGS.  16  to  18   . The electronic device  101  may identify and/or select, based on the selection of an object, an application (e.g., a second application to be described later) executed in a background mode corresponding to the object. For example, as illustrated in  FIG.  9   , the recent application  910  may identify that an object is selected (operation  915 ), and may transmit information indicating an application corresponding to the selected object to the processor  120 . 
     According to various embodiments, when the folding angle is changed in operation  705 , the electronic device  101  may display the execution screen of the second application while executing the second application corresponding to the first object selected in operation  706  in the foreground mode. As the relative positions of the housings (e.g., the first housing  835  and the second housing  836 ) of the electronic device  101  are changed according to the pivoting of the hinge (or the housings are rotated about the hinge), for example, as illustrated in  804  of  FIG.  8   , the angle (or the folding angle) between the housings (e.g., first housing  835  and second housing  836 ) may be changed from a second angle (e.g., 130 degrees) to a first angle (e.g., 180 degrees). As illustrated in  FIG.  9   , the processor  120  (e.g., the state control manager  635  of the window manager  636 ) of the electronic device  101  may acquire values detected by the sensors as the angle between the housings is changed, and may identify the folding state based on the values. The processor (e.g., the state control manager  635  of the window manager  636 ) may transmit information on the folding angle to a second application  920  selected based on the folding angle corresponding to (e.g., is included in or reaches) the first angle range. The second application  920  may identify that the second application  920  is selected (operation  921 ), identifies that the folding angle corresponds to a predetermined first angle range (e.g., 180 degrees) (operation  923 ), and may switch the background mode to the foreground mode (operation  925 ). Based on the switching of the second application  920  to the foreground mode, the electronic device  101  may display the execution screen  841  of the second application  920 , which is switched to the foreground module, on the display, as illustrated in  804  of  FIG.  8   . 
     A user interface (UI) in which objects (e.g., icons  851 ,  852 , and  853  and thumbnails  854 ,  855 , and  856 ) are displayed near the folding area is merely exemplary, and a person ordinarily skilled in the art will appreciate that there is no limit to the positions at which the items  851 ,  852 , and  853  and the thumbnails  854 ,  855 , and  856  are displayed and/or the positions of a corresponding touch area. For example, the objects (e.g., the icons  851 ,  852 , and  853  and the thumbnails  854 ,  855 , and  856 ) may be displayed in an area adjacent to side edges of the display module, and a touch area may be configured in the central area of the display module. 
     Hereinafter, another example of the operation of the electronic device  101  according to various embodiments is described with reference to  FIGS.  12  through  15   . 
     According to various embodiments, in the case of displaying a plurality of objects (e.g., the icons  1311  and the thumbnails  1312  of  FIG.  13   ) in the first area  831  based on the folding angle being in the second angle range, the electronic device  101  may configure a plurality of touch areas for selecting the plurality of objects (e.g., the icons  1311  and the thumbnails  1312 ) in a second area  1300  different from the first area  831 . The electronic device  101  may configure the plurality of touch areas at positions that can be easily touched by the user while the user holds the electronic device  101 , thereby improving the user&#39;s convenience of using the recent application. 
       FIG.  12    is a flowchart  1200  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  12    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  12    may be performed. Hereinafter, the operations of  FIG.  12    are described with reference to  FIGS.  13  to  15   . 
       FIG.  13    is a view for describing an example of an operation of implementing a plurality of touch areas in a second area  1300  of an electronic device  101  according to various embodiments.  FIG.  14    is a view for describing examples of shapes of touch areas according to various embodiments.  FIG.  15    is a view for describing an example of an operation of providing, when an object of an electronic device  101  according to various embodiments is selected, information associated with an application corresponding to the selected object. 
     According to various embodiments, the electronic device  101  may display the execution screen of a first application including at least one first object in operation  1201 . For example, based on the angle (or the folding angle) between the housings (e.g.,  835  and  836 ) corresponding to a first angle range (e.g., 180 degrees) (e.g., in an open state) as illustrated in  1301  of  FIG.  13   , the electronic device may display the execution screen  820  of the recent application including at least one first object (e.g., the icons  1311  and the thumbnails  1312 ). Since the operation of displaying the execution screen  820  of the recent application in the electronic device  101  may be performed like the above-described operation  701  of the electronic device  101 , a redundant description is omitted. 
     According to various embodiments, when the change of the folding angle is identified in operation  1202 , the electronic device  101  may display, in operation  1203 , at least one second object different from the at least one first object in the first area  831  of the display. For example, based on the angle (or the folding angle) between the housings (e.g.,  835  and  836 ) corresponding to the second angle range (e.g., 120 degrees to 160 degrees) as illustrated in  1302  of  FIG.  13   , the electronic device  101  may display, in the first area  831 , the execution screen of the recent application in which a plurality of objects (e.g., the icons  1311  and the thumbnails  1312 ) are arranged. The plurality of objects (e.g., at least one second object) displayed in the first area  831  have visual attributes (e.g., size) different from those of the plurality of previously displayed objects (e.g., at least one first object), but are described with reference to the same reference numerals  1311  and  1312  for convenience of description. Since operations  1202  and  1203  of the electronic device  101  may be performed in the same manner as operations  702  and  703  of the electronic device  101  described above, a redundant description thereof is omitted. 
     According to various embodiments, in operation  1204 , the electronic device  101  may configure at least one touch area for receiving an input for selecting the at least one second object (e.g., the icons  1311  and the thumbnails  1312 ) in second areas  1300  different from the first area  831 . As illustrated in  1302  of  FIG.  13   , the electronic device  101  may configure touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ), which correspond to objects, respectively, in the second area  1300 , which is a remaining area other than the first area  831 . The first area  831  may be disposed between the second areas  1300 . For example, a plurality of objects (e.g., the icons  1311  and the thumbnails  1312 ) may be disposed between a plurality of touch areas for selecting the plurality of objects (e.g., the icons  1311  and thumbnails  1312 ). Hereinafter, positions at which the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) are configured and visual attributes (e.g., at least one of shape, size, and color) of the touch areas are further described. 
     Hereinafter, examples of positions at which the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) are configured are described. 
     For example, the electronic device  101  may configure a touch area at a position associated with each of the objects in the second area  1300 . As an example, referring to  1302  of  FIG.  13   , the electronic device  101  may configure a first touch area  1321  at a position adjacent to the first icon in a lateral direction of the housing (e.g., leftward) from the first icon, which is disposed in a first column of the first sub-area  1131  of the second area  1300 , and may configure a second touch area  1324  at a position adjacent to the second icon in a lateral direction of the second housing  836  (e.g., rightward) from the first thumbnail disposed in a first column of the second sub area  1132 . The above-mentioned adjacent positions may include a position that is spaced apart from the objects (e.g., the icons and the thumbnails) by a predetermined distance, and a position that is in contact with the objects (or a position that is not spaced apart from the objects). 
     In addition, for example, the electronic device  101  may configure the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) such that the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) are spaced apart from side surface  1330  of the housings (or the side surface of the display) by a predetermined distance, as illustrated in  1302  of  FIG.  13   . For example, the touch area corresponding to the first icon may be spaced apart from the side surface of the first housing  835  by a predetermined distance, and the touch area corresponding to the first thumbnail may be spaced apart from the side surface  1330  of the second housing  836  by the predetermined distance. By configuring the touch areas at positions spaced apart by the predetermined distance, when the user holds the electronic device  101 , it may be possible to prevent an unintended input from being received on the touch areas by the user&#39;s hand which holds the electronic device  101 . The predetermined distance from the side surface  1330  of the housings may be configured based on the angle (or the folding angle) between the housings (e.g.,  835  and  836 ). For example, in some embodiments of the electronic device  101 , the smaller the folding angle, the larger the predetermined distance may be configured. In the electronic device  101 , by adjusting the predetermined distance for each folding angle, it may be possible to effectively prevent, for each folding angle, a touch input from being unintentionally made when the user holds the electronic device  101 . Alternatively or additionally, without being limited thereto, the disclosure may be implemented such that the predetermined distance is not present. 
     For example, as illustrated in  1302  of  FIG.  13   , in the electronic device  101 , the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) may be configured such that respective touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) are spaced apart from each other by a predetermined distance. In the electronic device  101 , by configuring the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) to be spaced apart from each other, it may be possible to prevent a touch area from being erroneously selected by the user. The distance between respective touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) may be configured based on the display positions and/or the order of priorities of the objects. For example, as the display position of an object is closer to at the uppermost end (e.g., at the uppermost row) or the center area, a distance by which another touch area is spaced apart from the touch area corresponding to the object may increase. For example, as the priority of an object is higher, a distance by which another touch area is separated from the touch area corresponding to the object may be increased. By adjusting the spacing distance between the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) in the electronic device  101 , it may be possible to allow the user to accurately select a touch area corresponding to a desired object. In some embodiments of the electronic device  101 , as the number of objects increases, the spacing distance between the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) may be configured to be narrower (e.g., reduced). 
     Hereinafter, visual attributes (e.g., at least one of size, shape, or color) of the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) are described. According to various embodiments, the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) configured in the electronic device  101  may have various types of visual attributes. The visual attributes may include at least one of size, shape, and color. For example, as illustrated in  1302  of  FIG.  13   , in the electronic device  101 , the touch areas may be configured in a rectangular shape or a band shape. Without being limited to those illustrated in the figure, in the electronic device  101 , the touch areas may be configured in various types of shapes, such as a circle, an ellipse, and a triangle that satisfy the above-described positions (e.g., a position adjacent to an object and/or a position spaced apart from the side of the housings). Hereinafter, various examples of shapes of the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) are further described. 
     According to various embodiments, in the electronic device  101 , a width w 1  of a row in which objects are arranged and a width w 2  of a row of the touch areas  1410  corresponding to the objects may be configured to be different from each other. For example, in the electronic device  101 , as illustrated in  1401  of  FIG.  14   , the width w 2  of the row of the touch areas  1410  may be configured to be narrower than the width w 1  of the row of the objects (e.g., the icons  1311 ). In the electronic device  101 , the width of each of the touch areas  1410  may be configured to gradually decrease in a direction from the first area  831  toward the side surface  1330  of the housing. In addition, for example, in the electronic device  101 , as illustrated in  1402  of  FIG.  14   , the width w 2  of the row of the touch areas  1410  may be configured to be wider than the width w 1  of the row of the objects (e.g., the icons  1311 ). In the electronic device  101 , the width of each of the touch areas  1410  may be configured to gradually increase in a direction from the first area  831  toward the side surface  1330  of the housing. As illustrated in  1401  and  1402  of  FIG.  14   , respective touch areas  1410  may be implemented to be spaced apart (g 1 , g 2 ) from each other. Alternatively or additionally, as illustrated in  1403  and  1404  of  FIG.  14   , respective touch areas  1410  may be implemented to be in contact with each other at terminal ends (e.g., portions adjacent to the side surface  1330  of the housing). 
     According to various embodiments, in the electronic device  101 , it may be possible to configure visual attributes of the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) based on information corresponding to the objects (e.g.,  1311  and  1312 ). For example, as illustrated in  1302  of  FIG.  13   , in the electronic device  101 , the colors of the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) corresponding to the objects may be configured based on the colors associated with the objects. As an example, the electronic device  101  may identify information on the color of at least one of an icon or a thumbnail, and may display the color of the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) corresponding to the icon and the thumbnail) with the identified color. The information on the color may include information on the most frequently used color (or representative color) among the colors included in the objects (e.g., the icons and/or the thumbnails), and information on the color corresponding to an average value of the values of a plurality of colors (e.g., the values of RGB and HSV color models) included in the objects (e.g., the icons and/or thumbnails). As another example, the electronic device  101  may identify information on the color of at least one of the icons or the thumbnails, and may display a pattern of a specific pattern (e.g., dots) based on the color in the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ). As the colors of the touch areas are configured by the colors corresponding to the objects, the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) may be visually distinguished from each other, and thus the touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ) may be improved in discrimination. 
     According to various embodiments, in operation  1205 , the electronic device  101  may receive an input on a first touch area among one or more touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ). When a user input is received on the touch area, the electronic device  101  may select an object corresponding to the touch area. For example, as illustrated in  1303  of  FIG.  13   , when a user input is received on the first touch area (e.g.,  1322 ), the electronic device  101  may select the first object (e.g., the first icon and/or the first thumbnail). The electronic device  101  may identify an application executed in a background mode corresponding to the selected object (e.g., the first icon and/or the first thumbnail). In addition, when a touch area associated with the touch area touched by the user is touched again, the electronic device  101  may deselect the object. For example, when the first touch area is touched and then touched again, the electronic device  101  may deselect the first object, or when the second touch area (e.g.,  1322 ) is touched after the first touch area (e.g.,  1322 ) is touched, the electronic device  101  may deselect the first object. The electronic device  101  may perform multi-touch for selecting a plurality of objects (e.g., the icons  1311  and the thumbnails  1312 ) through a plurality of touch areas (e.g.,  1321 ,  1322 ,  1323 ,  1324 , and  1325 ), which are described with reference to  FIGS.  16  to  18   . 
     According to various embodiments, the electronic device  101  may ignore an input unintended by a user on the touch areas. For example, the electronic device  101  may determine whether a user input is a valid input based on the attribute of the user input received on the first area  831  and/or the second area  1300 . The attribute of the input may include at least one of an area of the input, a sensitivity of the input, and a holding time of the input. For example, when the area of the user input is larger than a preconfigured area, the electronic device  101  may determine the user input as an invalid input. For example, the electronic device  101  may receive an input by the user&#39;s palm on the first area  831  and/or the second area  1300 . The electronic device  101  may identify the input by the palm as being larger than a preconfigured area, and ignore the input by the palm as an invalid input. The preconfigured area serving as a reference for determining whether or not the user inputs may be a preconfigured value in the electronic device  101 . In addition, for example, when the sensitivity of a user input is less than a preconfigured value, the electronic device  101  may determine the user input as an invalid input. For example, when the holding time of a user input is less than a preconfigured value, the electronic device  101  may determine the user input as an invalid input. 
     According to various embodiments, the electronic device  101  may display, in the second area  1300 , information related to an application corresponding to a touched touch area. For example, as illustrated in  FIG.  15   , the electronic device  101  may display information (e.g.,  1521 ,  1522 ,  1523 , and  154 ) associated with the applications corresponding to the objects (e.g., an icon  1511  and/or a thumbnail  1512 ) selected from the touched touch areas (e.g.,  1321 ,  1322 ,  1323 , and  1524 ). As illustrated in  FIG.  15   , information related to an application may be displayed in the selected touch area (e.g.,  1322 ), or may be displayed in an area other than the selected touch area. The information related to the application may include various kinds of information that may be acquired from an application, which is being executed in the background, and icons for executing functions, which are capable of being provided by the application. As an example, when the application is a message application, icons for providing a function of calling a recently received message and a function of calling a screen for writing a message may be displayed. 
     According to various embodiments, when the folding angle is identified as being changed in operation  1406 , in operation  1407 , while executing a second application corresponding to the first touch area in a foreground mode, the electronic device  101  may display the execution screen of the second application. For example, based on the angle (or the folding angle) between the housings (e.g.,  835 ,  836 ) corresponding to (e.g., is included in or reaches) a first angle range (e.g., 180 degrees) as illustrated in  1304  of  FIG.  13   , the electronic device  101  may execute the application, which corresponds to the selected object and is executed in the background, in a foreground mode. The electronic device  101  may display the execution screen  1341  of the application executed in the foreground mode. Since operations  1206  and  1207  of the electronic device  101  may be performed in the same manner as operations  705  and  706  of the electronic device  101  described above, a redundant description thereof is omitted. 
     According to various embodiments, based on a user input received on a plurality of touch areas for selecting a plurality of objects, the electronic device  101  may select two or more objects and may identify two or more applications corresponding to the selected two or more objects. 
       FIG.  16    is a flowchart  1600  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  16    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  16    may be performed. Hereinafter,  FIG.  16    is described with reference to  FIGS.  17  and  18   . 
       FIG.  17    is a view for describing an example of an operation of selecting a plurality of touch areas based on a user input of the electronic device  101  according to various embodiments.  FIG.  18    is a view for describing another example of an operation of selecting a plurality of touch areas based on a user input of the electronic device  101  according to various embodiments. 
     According to various embodiments, in operation  1601 , the electronic device  101  may display, in a first area  831  of the display, a plurality of second objects different from a plurality of first objects included in the execution screen of a first application, and in operation  1602 , the electronic device  101  may configure, in a second area  1300  different from the first area  831 , a plurality of touch areas for receiving an input for selecting the plurality of second objects. For example, as illustrated in  1701  of  FIG.  17  and  1801    of  FIG.  18   , based on the angle (or the folding angle) between the housings (e.g.,  835  and  836 ) being changed from the first angle range to the second angle range, the electronic device  101  may display, in the first area  831 , a plurality of objects (e.g., icons  1711  and thumbnails  1712 ), which are different from a plurality of objects of a recent application in visual attributes (e.g., size). The electronic device  101  may configure a plurality of touch areas (e.g.,  1713 ,  1714 ,  1811 ,  1821 ) for selecting a plurality of objects (e.g., icons  1711  and thumbnails  1712 ) in the second area  1300  other than the first area  831 . Since operations  1601  and  1602  of the electronic device  101  may be performed in the same manner as operations  1201  and  1204  of the electronic device  101  described above, a redundant description thereof is omitted. 
     According to various embodiments, the electronic device  101  may receive an input for selecting two or more objects among the plurality of second objects in operation  1603 . For example, the electronic device  101  may receive, on the first area  831 , an input for selecting a first object (e.g., the first icon and/or the first thumbnail) corresponding to the first application and an input for selecting a second object (e.g., the second icon and/or the second thumbnail) corresponding to the second application. Hereinafter, examples of an operation of receiving an input for selecting two or more objects through a plurality of touch areas (e.g.,  1713  and  1714 ) configured in the second area  1300  of the electronic device  101  are described. 
     According to various embodiments, the electronic device  101  may select two or more objects corresponding to touch areas selected according to a user input. 
     For example, as illustrated in  FIG.  17   , the electronic device  101  may select two or more objects based on a drag input received on a plurality of touch areas. As illustrated in  1701  of  FIG.  17   , when receiving a user input (e.g., a user&#39;s touch) on a first touch area (e.g.,  1716 ) among a plurality of touch areas (e.g.,  1715 ,  1716 , and  1717 ), the electronic device  101  may select a first object (e.g., the first icon  1721 ) corresponding to the first touch area (e.g.,  1716 ). The user input (e.g., a user&#39;s touch) received on the first touch area (e.g.,  1716 ) may be moved in the state of being maintained. The electronic device  101  identifies touch areas (e.g., a second touch area (e.g.,  1717 ) in  1701  of  FIG.  17   ) that are touched according to the movement of the user input (e.g., the user&#39;s touch), and may select an object (e.g., a second icon  1722 ) corresponding to the identified touch area. 
     For example, as illustrated in  1801  of  FIG.  18   , the electronic device  101  may select two or more objects based on the selection of touch areas  1811  and  1821  displayed in the areas corresponding to different housings (e.g.,  835  and  836 ). As illustrated in  1801  of  FIG.  18   , when receiving a user input received from a first touch area (e.g.,  1812 ) configured in the area corresponding to the first housing  835  in the second area  1300 , the electronic device  101  may select a first object (e.g., a first icon  1813  and/or a first thumbnail  1823 ) corresponding to the first touch area (e.g.,  1812 ), and when receiving a user input from a second touch area (e.g.,  1822 ) configured in the area corresponding to the second housing  836  in the second area  1300 , the electronic device  101  may select a second object (e.g., a second icon  1814  and/or a second thumbnail  1823 ) corresponding to the second touch area (e.g.,  1822 ). As described above, since the electronic device  101  performs an operation of selecting a plurality of objects through the touch areas configured in the different housings (e.g.,  835  and  836 ), the electronic device  101  may allow the user to easily select a plurality of objects in the state of holding the electronic device  101 . 
     According to various embodiments, the electronic device  101  may deselect at least some of objects selected according to a user input. 
     For example, the electronic device  101  may identify a touch area re-touched according to the movement of the user input (e.g., the user&#39;s touch), or may identify a touch area in which the movement of the touch in a different direction (e.g., in the opposite direction) and may deselect an object corresponding to the identified touch area. For example, as illustrated in  1702  of  FIG.  17   , when the second touch area (e.g.,  1717 ) is touched due to the movement of the touch in a first direction (e.g., downward) and then the touch moves in a direction different from (e.g., opposite to) the first direction on the second touch area (e.g.,  1717 ), the electronic device  101  may deselect an object (e.g., the second icon  1722 ) corresponding to the second touch area (e.g.,  1717 ). In this case, when the touch area corresponding to the position at which the touch movement started is re-touched, the electronic device  101  may maintain the selection of the object corresponding to the touch area. For example, as illustrated in  1702  of  FIG.  17   , even when the first touch area (e.g.,  1716 ) is re-touched due to the movement of the touch in the second direction, the electronic device  101  may maintain the selection of an object (e.g., the first icon  1721 ) corresponding to the first touch area (e.g.,  1716 ). 
     For example, in response to the selection of touch areas configured in different areas (e.g., a portion of the second area  1300  corresponding to the first housing  835  and a portion of the second area  1300  corresponding to the second housing  836 ) corresponding to specific objects, the electronic device  101  may deselect the objects. For example, as illustrated in  1902  of  FIG.  19    when a user touch is received on a third touch area (e.g.,  1815 ) corresponding to the second object, the electronic device  101  may deselect the second object (e.g., a third thumbnail  1824  and/or the second thumbnail  1823 ) selected as the user touch is received on the second touch area (e.g.,  1822 ). 
     According to various embodiments, the electronic device  101  may change visual attributes (e.g., at least one of shape, size, or color) in response to the change of the angle (or the folding angle) between the housings (e.g.,  835  and  836 ). 
       FIG.  19    is a flowchart  1900  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  19    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  19    may be performed. Hereinafter,  FIG.  19    is described with reference to  FIGS.  20  and  21   . 
       FIG.  20    is a view for describing an example of an operation of changing the size of an object in response to a change of the folding angle of an electronic device  101  according to various embodiments.  FIG.  21    is a view for describing an example of changing the size of an object according to various embodiments. 
     According to various embodiments, in operation  1901 , the electronic device  101  may display, in the first area  831  of the display, a plurality of objects included in the execution screen of a first application, and in operation  1902 , the electronic device  101  may configure, in a second area  2020 , different from the first area  831 , a plurality of touch areas for receiving an input for selecting the plurality of objects. For example, as illustrated in  2001  of  FIG.  20   , based on the angle (or the folding angle) between the housings (e.g.,  835  and  836 ) being changed from the first angle range to the second angle range, the electronic device  101  may display, in the first area  831 , a plurality of objects (e.g., icons  2011  and thumbnails  2012 ), which are different from a plurality of objects included in the execution screen of a recent application in visual attributes (e.g., size). The electronic device  101  may configure a plurality of touch areas (e.g., second areas  2020 ) for selecting a plurality of objects (e.g., the icons  2011  arranged in the first sub-area  1131  and the thumbnails  2012  arranged in the second sub-area  1132 ) in the second area  2020  other than the first area  831 . Since operations  1901  and  1902  of the electronic device  101  may be performed in the same manner as operations  1301  and  1304  of the electronic device  101  described above, a redundant description thereof is omitted. 
     According to various embodiments, when the folding angle is changed in operation  1903 , the electronic device  101  may change the sizes of the plurality of objects and display the size-changed objects in operation  1904 . For example, when the folding angle is changed in the state in which the folding angle is included in the second angle range, the electronic device  101  may dynamically change the sizes of the plurality of objects displayed in the first area  831 . When the folding angle is changed and reaches the first angle range, the electronic device  101  may switch the execution screen of the recent application and may display an execution screen in a specific layout (e.g., a carousel form). As an example, as illustrated in  2001  and  2002  of  FIG.  20   , when the folding angle decreases, the electronic device  101  may gradually decrease the sizes of the objects (e.g., thumbnails  2012 ), and when the folding angle increases, the electronic device  101  may gradually increase the sizes of the objects (e.g., thumbnails  2012 ). As an example, as illustrated in  2101  of  FIG.  21   , when displaying thumbnails of a message application, the electronic device  101  may resize the thumbnails (e.g., increases the size of the thumbnails) of the message application as the folding angle changes and display the resized thumbnails. The electronic device  101  may change the area of the first area (e.g.,  1132 ) in response to the change of the folding angle, and may change the sizes of the objects to correspond to the changed area of the first area (e.g.,  1132 ) (e.g.,  2110 ,  2111 , and  2112 ). Although  FIG.  20    illustrates that only the sizes of the thumbnails  2012  are changed, but the disclosure is not limited thereto, and the sizes of the icons  2011  may also be changed. While changing the sizes of the objects, the electronic device  101  may change the sizes of the plurality of touch areas (e.g.,  2020 ) corresponding to the objects to correspond to the changed sizes of the objects. For example, as illustrated in  2002  of  FIG.  20   , when the sizes of the objects decrease as the folding angle decreases, the electronic device  101  may increase the areas of touch areas (e.g.,  2020 ) corresponding to the objects. When the sizes of the objects increase as the folding angle increase, the electronic device  101  may decrease the areas of the touch areas (e.g.,  2020 ) corresponding to the objects. Without being limited thereto, when the folding angle is decreased, the sizes of the objects may be increased, and when the folding angle is increased, the sizes of the objects may be decreased. Hereinafter, other examples of operations for changing the sizes of objects are described. 
     According to various embodiments, as the folding angle is changed, the electronic device  101  may change the area of the first area (e.g.,  1132 ) and may display various kinds of information in an area other than the area in which the objects (e.g., icons and/or thumbnails) are displayed in the first area  831  having the changed area. For example, as illustrated in  2102  of  FIG.  21   , when the area of the first area (e.g.,  1132 ) is increased as the folding angle is increased, the electronic device  101  may display, in an area (e.g.,  2122  or  2133 ) of the area-increased first area (e.g.,  1132 ) other than the area  2121  in which the thumbnails are displayed, information on an application associated with the thumbnails. The size of an area  2121  in which an object (e.g., an icon and/or a thumbnail) is displayed may be fixed on the first area (e.g.,  1132 ), and as the area of the first area  1132  is increased, the electronic device  101  may identify the remaining areas (e.g.,  2122  and  2133 ) other than the area  2121  in which the objects are displayed, on the first area (e.g.,  1132 ). Information on applications displayed in the areas  2122  and  2133  other than the area  2121  in which the thumbnails are displayed may include information which is capable of being provided by the applications. For example, as illustrated in  2102  of  FIG.  21   , a message application may provide information on the number of messages currently received from other devices and information on the contents of the received messages. In some embodiments, the electronic device  101  may display various kinds of information related to services provided by various other applications in an area other than the area in which the thumbnails are displayed. For example, when the thumbnails displayed in the first area (e.g.,  1132 ) correspond to various applications (e.g., a gallery app), in response to the increase of the size of the first area, the electronic device  101  may acquire the various kinds of information associated with the services provided by the various other applications (e.g., information on the number of stored images) and may display the acquired information. 
     According to various embodiments, the electronic device  101  may identify information on a position associated with a user, and change the positions of objects  2310  based on the position associated with the user. 
       FIG.  22    is a flowchart  2200  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  22    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  22    may be performed. Hereinafter, the operations of  FIG.  22    are described with reference to  FIGS.  23  to  24   . 
       FIG.  23    is a view for describing an example of an operation of changing the position of an object of an electronic device  101  according to various embodiments based on the position of a user input.  FIG.  24    is a view for describing an example of an operation of changing the position of an object of an electronic device  101  according to various embodiments based on the position of a line of sight of a user. 
     According to various embodiments, in operation  2201 , the electronic device  101  may display, in the first area  831  of the display, a plurality of objects included in the execution screen of a first application, and in operation  2202 , the electronic device  101  may configure, in a second area different from the first area  831 , a plurality of touch areas for receiving an input for selecting the plurality of objects. For example, as illustrated in  2301  of  FIG.  23   , based on the angle (or the folding angle) between the housings (e.g.,  835  and  836 ) being changed from the first angle range to the second angle range, the electronic device  101  may display a plurality of objects  2310  (e.g., icons and thumbnails) of a recent application in a first area  831  corresponding to the hinge. The electronic device  101  may configure a plurality of touch areas for selecting the plurality of objects  2310  in a second area other than the first area  831 . Since operations  2201  and  2202  of the electronic device  101  may be performed in the same manner as operations  1301  to  1304  of the electronic device  101  described above, a redundant description is omitted. 
     According to various embodiments, in operation  2203 , the electronic device  101  may identify information associated with to the user&#39;s position, and in operation  2204 , the electronic device  101  may change the display positions of the plurality of objects  2310  based on the information associated with the identified user&#39;s position. For example, the information associated with the position of the user may include the position of the user&#39;s touch and the position of a line of sight of the user. Hereinafter, examples of operations of changing the display positions of the plurality of objects  2310  of the electronic device based on information associated with the position of the user. 
     First, an operation of changing the display positions of objects  2310  based on the position of a user input is described. 
     According to various embodiments, the electronic device  101  may determine whether or not conditions for moving the positions of the plurality of objects  2310  are satisfied, and when the conditions are satisfied, the electronic device  101  may move the positions of the plurality of objects  2310 . For example, the conditions being satisfied may include a case in which the attributes of a received touch (e.g., at least one of sensitivity or holding time) satisfy preconfigured values. As an example, when the sensitivity and holding time of a received user&#39;s touch exceed preconfigured values, the electronic device  101  may change the positions of the plurality of objects  2310  based on the position of the user&#39;s touch. 
     According to various embodiments, the electronic device  101  may change the display positions of the objects  2310  based on the position at which a user input (e.g., a touch) is received. The electronic device  101  may identify an area of the display corresponding to the position at which a user input is received, and move the first area  831  in which the objects  2310  are displayed to the identified area of the display. For example, as illustrated in  2301  and  2302  of  FIG.  23   , the electronic device  101  may move the first area  831  in which the plurality of objects  2310  are displayed to a position associated with (e.g., adjacent to) the position at which a user input (e.g., a touch) is received. The objects  2310  may be displayed in the first area  831  of which the position has been moved. The electronic device  101  may move and display the positions of the objects  2310  to positions spaced apart by a predetermined distance from the position at which a user&#39;s touch is received. Accordingly, the electronic device  101  may prevent the moved and displayed objects  2310  from being covered the user&#39;s hand. 
     According to various embodiments, based on the position at which a user input is received, the electronic device  101  changes the size of the moved first area  831 , and may change the number of objects  2310  displayed in the size-changed first area  831 . When the moved first area  831  is identified as being out of the display based on the movement of the first area  831 , the electronic device  101  may change the size of the first area  831 . For example, as illustrated in  2203  and  2204  of  FIG.  23   , the electronic device  101  may receive a user input in the lower area of the display corresponding to each of the housings  835  and  836 . When the first area is moved to the lower area of the display in which the user input is received, the electronic device may identify that the moved first area is out of the display. The electronic device  101  may perform an operation of comparing the position of the area of the display with the position of the first area to change the size (e.g., reduce the size) of the first area such that the first area is not out of the display. As illustrated in  2303  and  2304  of  FIG.  23   , the electronic device  101  may reduce the number of objects  2310  such that the plurality of objects  2310  are displayed in the first area of the changed size. The electronic device may select a plurality of objects  2310  to be displayed among the plurality of objects displayed before the first area  831  is moved, based on the order of priorities of the plurality of objects. For example, the electronic device may select a predetermined number of objects  2310  displayable in the size-changed first area  831  in the order of the priorities from the highest priority. The electronic device may allow the remaining unselected objects to be displayed when the plurality of objects  2310  are scrolled. 
     According to various embodiments, the electronic device may change the display size of the moved objects  2310 . For example, as illustrated in  2303  and  2304  of  FIG.  23   , the electronic device may increase the size of the objects  2310  to cause the objects  2310  to be displayed in the increased size. 
     Hereinafter, an example of an operation of changing the display positions of the objects  2310  based on the position a line of sight of the user is described. 
     According to various embodiments, the electronic device  101  may move the display positions of the objects  2310  based on the position of a line of sight of the user, as illustrated in  FIG.  24   . The electronic device  101  may photograph at least a portion of the user&#39;s body (e.g., face, shoulder, and torso) by using a provided camera. The electronic device  101  may calculate at least one of a rotation degree or two-dimensional coordinates of the user&#39;s body from a captured image of the at least a portion of the user&#39;s body. Based on at least one of the calculated rotation degree or the two-dimensional coordinates of the user&#39;s body, the electronic device  101  may identify an area facing the user among the areas of the display corresponding to the two housings (e.g.,  835  and  836 ), and may move/display the plurality of objects  2310  to/in the identified area. For example, as illustrated in  2401  of  FIG.  24   , when the user is identified as facing the area of the display corresponding to the second housing  836 , the electronic device  101  may move/display the plurality of objects  2310  to/in the area of the display corresponding to the second housing  836 . In addition. for example, as illustrated in  2402  of  FIG.  24   , when the user is identified as facing the area of the display corresponding to the first housing  835 , the electronic device  101  may move/display the plurality of objects  2310  to/in the area of the display corresponding to the first housing  835 . 
     According to various embodiments, while moving the plurality of objects  2310 , the electronic device  101  may adjust the positions configured for the plurality of touch areas corresponding to the plurality of objects  2310  according to the movement of the plurality of objects  2310 . For example, when the first area  831  is moved, the electronic device  101  may move/display the plurality of touch areas to/at positions adjacent to the first area  831 . 
     According to various embodiments, when two or more objects are selected, the electronic device  101  may configure displaying forms of the execution screens of the applications corresponding to the two or more objects based on the change pattern of the folding angle between the housings (e.g.,  835  and  836 ). The displaying form may include a multi-window form, a pop-up window form, and a form in which multi-windows and pop-up windows are combined. 
       FIG.  25    is a flowchart  2500  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  25    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  25    may be performed. Hereinafter,  FIG.  25    is described with reference to  FIGS.  26  through  28   . 
       FIG.  26    is a view for describing an example of an operation of displaying screens of a plurality of applications of an electronic device  101  according to various embodiments in a multi-window form.  FIG.  27    is a view for describing an example of an operation of displaying screens of a plurality of applications of an electronic device  101  according to various embodiments in a pop-up window form.  FIG.  28    is a view for describing an example of an operation of displaying screens of a plurality of applications of an electronic device  101  according to various embodiments in a form in which multi-windows and pop-up windows are combined. 
     According to various embodiments, in operation  2501 , the electronic device  101  may display, in a first area  831 , a plurality of second objects which are different from a plurality of first objects included in the execution screen of a first application, and may configure touch areas in a second area. For example, as illustrated in  2601  of  FIG.  26 ,  2701    of  FIG.  27   , and  2801  of  FIG.  28   , based on the angle (or the folding angle) between the housings (e.g.,  835  and  836 ) being changed from the first angle range to the second angle range, the electronic device  101  may display a plurality of objects (e.g., icons and thumbnails) of a recent application in the first area  831  corresponding to the hinge. The electronic device  101  may configure a plurality of touch areas for selecting the plurality of objects  2611 ,  2612 ,  2613 , and  2614  in a second area other than the first area  831 . Since operation  2501  of the electronic device  101  may be performed like the above-described operations  1201  to  1204  of the electronic device  101 , a redundant description is omitted. 
     According to various embodiments, the electronic device  101  may receive an input for selecting two or more objects among the plurality of objects in operation  2502 . For example, based on a user input being received on two or more touch areas among the plurality of touch areas configured in the second areas, the electronic device  101  may select two or more objects corresponding to the touched two or more touch areas among the plurality of objects  2611 ,  2612 ,  2613 , and  2614 . Since operation  2502  of the electronic device  101  may be performed like the above-described operation  1703  of the electronic device  101 , a redundant description is omitted. 
     According to various embodiments, when the folding angle is identified as being changed in operation  2503 , the electronic device  101  may identify the change pattern of the folding angle θ in operation  2504 . The change pattern of the folding angle θ may include change trends of the folding angle θ, such as a trend in which the folding angle increases and a trend in which the folding angle decreases after increasing. As described above, the displaying form may include a multi-window form, a pop-up window form, and a form in which multi-windows and pop-up windows are combined. Based on the identified change pattern of the folding angle θ, the electronic device  101  may determine a displaying form of execution screens of applications corresponding to two or more objects. Hereinafter, examples of operations of displaying execution screens based on the change pattern of the folding angle θ of the electronic device  101  are described. The operations of the electronic device  101  described below are merely examples, and the displaying forms of execution screens may be determined based on various change patterns of the folding angle. 
     According to various embodiments, in operation  2505 , based on the change pattern being a first pattern, the electronic device  101  may display the execution screens of applications corresponding to two or more objects in a multi-window form. For example, when the change pattern of the folding angle θ is a pattern indicating an increasing trend (e.g., increasing from 130 degrees to 180 degrees), the electronic device  101  may display the execution screens of applications corresponding to the selected two or more objects in divided screens (e.g., displaying the execution screen in a multi-window form). For example, as illustrated in  2601  of  FIG.  26   , after two or more objects are selected in the state in which the folding angle θ between the housings (e.g.,  835  and  836 ) is a second angle, the folding angle θ may be changed to a first angle range. For example, the folding angle between the housings (e.g.,  835  and  836 ) may increase from the second angle and change to a folding angle included in the first angle range. The electronic device  101  may identify a value received from a sensor while the folding angle increases, and based on the value, the electronic device  101  may identify that the folding angle increases from the second angle and identify that the change pattern of the folding angle exhibits a trend in which the angle increases. Based on the identified change pattern, the electronic device  101  may display execution screens of applications in multi-window forms as illustrated in  2602 ,  2603 , and  2604  of  FIG.  26   . In order to ensure that the execution screens of applications do not overlap each other, the electronic device  101  may divide the display into as many areas as the number of the applications and may display the execution screens of the applications in respective divided areas of the display. For example, when two objects are selected as illustrated in  2602  of  FIG.  26   , the electronic device  101  may divide the display into two areas, and may display an execute screen of an application corresponding to each of the objects in each of the two divided areas. For example, when three objects are selected as illustrated in  2603  of  FIG.  26   , the electronic device  101  may divide the display into three areas, and may display the execution screens of three applications. In addition, when five objects are selected as illustrated in  2604  of  FIG.  26   , the electronic device  101  may divide the display into five areas to display five execution screens. The divided areas of a display illustrated in  FIG.  26    are merely examples, and respective areas may be configured to have sizes different from the illustrated sizes. The electronic device  101  may configure the size of one area among a plurality of areas to be larger than the size of the other areas (e.g., configures the size of one area to be the largest), and may display the execution screen of an application in the one area based on the order of priorities of the applications. For example, the electronic device  101  may display the execution screen of the application having the highest priority in the one area having the largest size among the divided areas. For example, the order of priorities may be configured such that an application that has been most recently controlled by a user interaction (or the highest activity stack) and is being executed in a background mode has the highest priority. For example, the order of priorities may be configured such that an application corresponding to a touch area touched earlier by a user input has a higher priority. 
     According to various embodiments, in operation  2506 , based on the change pattern being a second pattern, the electronic device  101  may display the execution screens of applications corresponding to two or more objects in a pop-up window form. For example, when the change pattern of the folding angle is a pattern exhibiting a trend in which the folding angle decreases and then increases, the electronic device  101  may display some of the execution screens of the applications corresponding to the selected two or more objects in a pop-up window form. For example, the third angle range (e.g., 90 degrees to 120 degrees) may be a smaller angle range than the second angle range (e.g., 120 degrees to 160 degrees). In the state in which the angle between the housings (e.g.,  835  and  836 ) is included in the second angle range, as the relative positions of the housings (e.g.,  835  and  836 ) are changed according to the pivoting of the hinge (or the rotating of the housings about the hinge), the angle may be included in the third angle range. After the angle is included in the third angle range (e.g., 90 degrees to 120 degrees), as the relative positions of the housings (e.g.,  835  and  836 ) are changed again according to the pivoting of the hinge, the angle may increase and may be included in the first angle range (e.g., 180 degrees). Based on values identified from a sensor while the angle is being changed, the electronic device  101  may identify that the angle change pattern exhibits a trend in which the angle decreases and then increases again. As illustrated in  2702 ,  2703 ,  2704 , and  2705  of  FIG.  27   , based on the identified angle change pattern, while displaying the execution screen of an application among the execution screens of applications corresponding to the selected two or more objects, the electronic device  101  may display the execution screens of the remaining applications in the pop-up windows  2720 . Based on the order of priorities of the applications, while displaying the execution screen of an application having the highest priority, the electronic device  101  may display the execution screens of the other remaining applications in the pop-up windows  2720 . A redundant description of the order of priorities is omitted. 
     According to various embodiments, as illustrated in  2802  of  FIG.  28   , the electronic device  101  may display execution screens of a plurality of applications in a form in which multi-windows and pop-up windows are combined. For example, when the change pattern of the folding angle is a pattern in which an angle increasing trend and an angle decreasing trend are repeated, the electronic device  101  may display the execution screens of a plurality of applications in a form in which a multi-window form and a pop-up window form are combined. In some embodiments, the electronic device  101  may determine the number of execution screens displayed in the divided screens and the number of execution screens displayed in the pop-up windows based on the number of inflection points of angle changes identified as the folding angle increasing trend and the folding angle decreasing are repeated. For example, in the case where a trend in which the folding angle decreases and the increases while the folding angle is changed from the above-described change pattern is identified twice, the electronic device  101  may display the execution screens of two applications corresponding to two objects among the selected objects in divided screens, and may display the execution screens of the applications corresponding to the remaining objects in pop-up windows. In this case, based on the order of priorities of the applications (e.g., from the highest priority) corresponding to the selected objects, (e.g., from the highest priority), the electronic device  101  may select the applications to be displayed in the divided screens. 
     As described above, the angle change patterns corresponding to the above-described displaying forms (e.g., a multi-window form, a pop-up window form, and a form in which a multi-window and a pop-up window are combined) are merely examples, and may be implemented in various angle change patterns. For example, when an angle change pattern exhibits a trend in which the angle decreases and then increases, the electronic device  101  may display the execution screens of a plurality of applications in a pop-up window pattern. For example, when an angle change pattern exhibits a trend in which the angle increases, the electronic device  101  may display the execution screens of a plurality of applications in a multi-window form. 
     The above-described operations of displaying the execution screens of applications corresponding to a plurality of selected objects by the electronic device  101  may also be applicable to various other types of electronic devices  101 . 
     According to various embodiments, an electronic device  101  (e.g., the electronic device  101  in  FIG.  30   ), which is implemented such that the relative positions of the housings (e.g.,  835  and  836 ) are changed according to the pivoting of the hinge up and down, may perform an operation of displaying the execution screens of applications corresponding to a plurality of objects. 
       FIG.  29    is a flowchart  2900  for describing examples of operations of an electronic device  101 , which is implemented such that the relative positions of the housings are changed up and down according to the pivoting of the hinge according to various embodiments of the disclosure. According to various embodiments, the operations illustrated in  FIG.  29    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  29    may be performed. Hereinafter, the operations of  FIG.  29    are described with reference to  FIG.  30   . 
       FIG.  30    is a view for describing examples of operations of an electronic device  101 , which is implemented such that the relative positions of the housings are changed up and down according to the pivoting of the hinge according to various embodiments. 
     According to various embodiments, in operation  2901 , the electronic device  101  of  FIG.  30    may display, in a first area, a plurality of second objects different from a plurality of first objects included in the execution screen of the first application. For example, as illustrated in  3001  of  FIG.  30   , when the relative positions of the first housing  835  and the second housing  836  are changed according to the pivoting of the hinge and thus the angle between the housings is included in the second angle range, the electronic device  101  may display, in the first area  831 , objects  3010  (e.g., icons and thumbnails) having visual attributes (e.g., size) different from those of the objects included in the first application (e.g., a recent application). The first area  831  may be an area corresponding to the hinge of the electronic device  101  (e.g., the area of a display that is bent according to the change of relative positions of the housings according to the pivoting of the hinge). Since operation  2901  of the electronic device  101  may be performed like the above-described operation  701  of the electronic device  101 , a redundant description is omitted. 
     According to various embodiments, in operation  2902 , the electronic device  101  of  FIG.  30    may receive a selection of a plurality of objects on the first area. For example, the electronic device  101  may receive a user input for selecting at least one of a plurality of objects displayed on the first area. In the case where the electronic device  101  implemented such that the relative positions of the housings (e.g., the first housing  835  and the second housing  836 ) are changed up and down according to the pivoting of the hinge, a user may easily hold the electronic device  101  with one hand. Accordingly, the electronic device  101  may not perform an operation of configuring a plurality of touch areas in an area other than the first area  831 , and may receive a user input on the objects  3010  displayed on the first area  831 . 
     According to various embodiments, when the electronic device  101  is rotated (e.g., rotated clockwise or counterclockwise), the electronic device  101  may also rotate and display the plurality of objects  3010  displayed in the first area, and may configure a plurality of touch areas for selecting the plurality of objects  3010  in the second area other than the first area. Since the operation of configuring a plurality of touch areas in the electronic device  101  may be performed like the above-described operation  1204  of the electronic device  101 , a redundant description is omitted. 
     According to various embodiments, the electronic device  101  of  FIG.  30    may display the execution screens of a plurality of applications corresponding to a plurality of objects selected in operation  2903 . For example, as illustrated in  3002 ,  3003 , and  3004  of  FIG.  30   , the electronic device  101  may display the execution screens of a plurality of applications in a multi-window displaying form  3002 , a pop-up window displaying form  3003 , or a form in which multi-widows and pop-up windows are combined  3004 . As described with reference to  FIGS.  27  to  28   , the electronic device  101  may identify the display form based on an angle change pattern and may display the execution screens of a plurality of applications based on the identified displaying form. Accordingly, a redundant description is omitted. When the electronic device  101  displays the execution screens of applications in a pop-up display form, the electronic device  101  may display the execution screens of the applications in the pop-up window as  2720  in  FIG.  30    or may display pop-up windows including icons for calling the execution screens of the applications as  2730  in  FIG.  30   . 
     Hereinafter, embodiments in which the above-described operations of the electronic device  101  are applied to electronic devices  101  having various form factors is described. 
     According to various embodiments, in an electronic device  101  of a type in which a plurality of areas are formed in a flexible display as well, the execution screen of the first application (e.g., a recent application) may be changed based on the folding angles between the plurality of housings provided in the electronic device  101 . For example, an electronic device  101  of a type in which three areas are formed in a flexible display (e.g., a Z fold type) may identify a plurality of angles (or folding angles) between the housings  3211 ,  3212 , and  3213 , and, based on the plurality of angles, the electronic device  101  may change the display positions of objects  3221  included in the execution screen of the first application (e.g., a recent application). In addition, the electronic device  101  may display the execution screen of an application which corresponds to an object selected based on the plurality of angles and is executed in a background mode. Hereinafter, the electronic device  101  of a type in which three areas are formed in a flexible display (e.g., a Z-fold type) is described as an example, but the following descriptions may also be applicable to an electronic device of a type in which more areas are formed. 
       FIG.  31    is a flowchart  3100  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  31    are not limited to the illustrated order, and may be performed in various orders, a greater or smaller number of operations compared to the operations illustrated in  FIG.  31    may be performed. Hereinafter,  FIG.  31    is described with reference to  FIGS.  32  and  33   . 
       FIG.  32    is a view for describing an example of an operation of an electronic device  101  in a type in which three areas are formed (e.g., a Z-fold type) in a flexible display according to various embodiments.  FIG.  33    is a view for describing another example of an operation of an electronic device  101  of a type in which three areas are formed (e.g., a Z-fold type) in a flexible display according to various embodiments. 
     According to various embodiments, in operation  3101 , an electronic device  101  may display the execution screen of a first application including a plurality of first objects. For example, as illustrated in  3201  of  FIG.  32   , the electronic device  101  may display the execution screen of a recent application including a plurality of first objects (e.g., icons and/or thumbnails). Operation  3101  of the electronic device  101  may be performed like the above-described operation  801  of the electronic device  101  in which two areas are formed in the flexible display, a redundant description is omitted. 
     According to various embodiments, in operation  3102 , the electronic device  101  may identify angles between the plurality of housings  3211 ,  3212 , and  3213 . For example, the relative positions of the plurality of housings  3211 ,  3212 , and  3213  may be changed according to the pivoting of hinges to each of which two adjacent housings included in the electronic device  101  are connected. Among the plurality of housings  3211 ,  3212 , and  3213 , as the relative positions of adjacent housings (e.g., the first housing  3211  and the second housing  3212  or the second housing  3212  and the third housing  3213 ) are changed according to the pivoting of a hinge, respective housings may form a folding angle relative to each other. For example, as the relative positions of the housings  3211 ,  3212 , and  3213  are changed according to the pivoting of the hinges as illustrated in  3202  of  FIG.  32   , a first folding angle between the first housing  3211  and the second housing  3212  may be formed as a first angle, and a second folding angle between the second housing  3212  and the third housing  3213  may be formed as a second angle. Based on values identified from a sensor as the relative positions of the three housings  3211 ,  3212 , and  3213  are changed according to the pivoting of the hinges, the electronic device  101  may identify the above-mentioned angles (e.g., the first angle and the second angle). The sensor may be provided in each of the first housing  3211  and the third housing  3213 . For example, the first sensor may be provided in the first housing  3211  to identify a value when the relative position of the first housing  3211  or the second housing  3212  is changed (or rotated), and the second sensor may be provided in the third housing  3213  to identify a value when the relative position of the second housing  3212  or the third housing  3213  is changed (or rotated). 
     According to various embodiments, in operation  3103 , the electronic device  101  may determine whether the identified angles satisfy conditions for switching the execution screen of the first application. For example, when the conditions are satisfied, it may include a case in which a plurality of identified angles are included in a predetermined angle range. For example, in order to determine whether the conditions are satisfied, the electronic device  101  may determine whether the angles are included in predetermined different angle ranges, respectively. As an example, as illustrated in  3201  of  FIG.  32   , when the folding angle between the first housing  3211  and the second housing  3212  is included in a second angle range (e.g., 210 to 240 degrees) and the folding angle between the second housing  3212  and the third housing  3213  is included in a third angle range (e.g., 120 to 160 angles), and when the folding angle between the second housing  3212  and the third housing  3213  is included in the third angle range (e.g., 120 degrees to 160 degrees), the electronic device  101  may initiate an operation of switching the execution screen of a recent application (e.g., changing the sizes and/or positions of a plurality of objects  3221 ). For example, in order to determine whether the conditions are satisfied, the electronic device  101  may determine whether at least one of the angles is included in a predetermined angle range. For example, the electronic device  101  may determine whether the second angle between the second housing  3212  and the third housing  3213  is included in the third angle range (e.g., 120 degrees to 160 degrees) as illustrated in  3301  of  FIG.  33    or whether the first angle between the first housing  3211  and the second housing  3212  is included in the third angle range (e.g., 120 degrees to 160 degrees) as illustrated in  3302  of  FIG.  33   . When at least one of the first angle or the second angle is included in the third angle range, the electronic device  101  may initiate an operation of switching the execution screen of the recent application (e.g., changing the positions of the plurality of objects  3221 ). 
     According to various embodiments, when the conditions are identified as being satisfied in operation  3104 , in operation  3105 , the electronic device  101  may configure touch areas (e.g.,  3222  and  3223 ) in a second area while displaying, in a first area of the display, at least one second object (e.g.,  3221 ) different from at least one first object. Hereinafter, the first area in which the second object is displayed and the second area in which the touch areas are configured are described. 
     According to various embodiments, the electronic device  101  may display a plurality of objects  3221  in the first area of the display corresponding to one housing, and may display touch areas in second areas of the display corresponding to remaining housings  3211 ,  3212 , and  3213 . As an example, as illustrated in  3202  of  FIGS.  32  and  3301  and  3302    of  FIG.  33   , the electronic device  101  may identify the area of the display, which corresponds to the second housing  3212  located between the first housing  3211  and the third housing  3213 , as the first area and may display a plurality of objects  3221  in the first area. The electronic device may identify the remaining areas of the display, which correspond to the first housing  3211  and the third housing  3213 , respectively, as the second area, and may configure a plurality of touch areas  3222  and  3223  in each of the areas. In this case, the electronic device  101  may change the sizes of the objects (e.g., icons and/or thumbnails)  3221  to correspond to the size of the first area and then display the objects (e.g., icons and/or thumbnails) in the first area. The first area corresponding to the second housing  3212  may include sub-areas, and may include different types of objects (e.g., icons and thumbnails) in respective sub-areas. Since the operation of changing the sizes of the objects  3221  in the electronic device  101  has been described above, a redundant description thereof is omitted. In addition, since the operation of configuring a plurality of touch areas in the electronic device  101  has been described above, a redundant description thereof is omitted. 
     According to various embodiments, when the above-mentioned two or more objects are selected in the electronic device  101  of the type in which three areas are formed in a flexible display (e.g., Z-fold type), based on a folding angle change pattern, the electronic device  101  may display the execution screens of applications corresponding to the two or more object like the above-described displaying forms of an electronic device  101  (e.g., a multi-window form, a pop-up window form, or a form in which the multi-window form and the pop-up window form are combined). A redundant description is omitted. 
     According to various embodiments, an electronic device  101  including a structure in which a roller (e.g.,  451 ) is provided and a flexible display is exposed to the outside according to the rotation of the roller (e.g.,  451 ) (hereinafter, referred to as a rollable electronic device  101 ) may switch the execution of a first application (e.g., a recent application) based on the area of the exposed area of the flexible display. 
       FIG.  34    is a flowchart  3400  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  34    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  34    may be performed. Hereinafter, the operations of  FIG.  34    are described with reference to  FIG.  35   . 
       FIG.  35    is a view for describing an example of an operation of switching the execution screen of the first application based on the exposed area of the flexible display of the rollable electronic device  101  according to various embodiments. 
     According to various embodiments, in operation  3401 , the rollable electronic device  101  may display the execution screen of the first application including a plurality of objects. For example, as a structure (e.g., a first structure) slides according to the rotation of the roller as illustrated in  3501  of  FIG.  35   , the rollable electronic device  101  may display the execution screen of the recent application including a plurality of objects (e.g., icons and/or thumb nails) in the state in which a partial area  3510  of the display is exposed. Since the operation of displaying the execution screen of the recent application in the rollable electronic device  101  may be performed like the above-described operation  701  of the electronic device  101 , a redundant description is omitted. 
     According to various embodiments, in operation  3402 , the rollable electronic device  101  may identify that the exposed area of the display is changed, and in operation  3403 , the rollable electronic device  101  may configure the touch areas in the second area while transforming objects included in the execution screen of the first application and the objects in the first area of the display. For example, in the rollable electronic device  101 , as the structure (e.g., the first structure (e.g.,  401 )) slides according to the rotation of the roller, a partial area of the display may be inserted into the inside of the rollable electronic device  101  (e.g., the second structure (e.g.,  402 )). Based on a value identified from a sensor based on a partial area  3510  of the display, the rollable electronic device  101  may identify that the partial area of the display is inserted into the inside. Based on a partial area of the display being inserted into the inside, the rollable electronic device  101  may display, in the first area of the exposed area of the display, a plurality of objects  3511  different (e.g., different in visual attributes) from a plurality of objects (e.g., icons and/or thumbnails) included in the execution screen of the recent application. As illustrated in  3502  of  FIG.  35   , only objects of a single type (e.g., icons or thumbnails) may be displayed in the first area, or without being limited thereto, different types of objects (e.g., icons and thumbnails) may be displayed together in the first area, as described above. The rollable electronic device  101  may configure a plurality of touch areas for selecting a plurality of objects  3512 , in the second area other than the first area. As illustrated in  3502  of  FIG.  35   , the plurality of touch areas  3512  may be displayed at positions adjacent to a side portion  3522  of the display, and the plurality of objects  3511  may be disposed at positions adjacent to the side surface  3521  of the electronic device into which the display is introduced. Alternatively or additionally, without being limited thereto, the plurality of touch areas  3512  may be displayed at positions adjacent to the side surface  3521  of the electronic device into which the display is introduced, and the plurality of objects  3511  may be displayed at positions adjacent to the side portion  5322  of the display. Since the operation of displaying the plurality of objects  3511  and the operation of configuring the plurality of touch areas  3512  in the rollable electronic device  101  may be performed like the above-described operations of the electronic device  101 , a redundant description is omitted. 
     According to various embodiments, in operation  3404 , the rollable electronic device  101  may receive an input for selecting at least one object among the plurality of objects  3511 . For example, as illustrated in  3503  of  FIG.  35   , the rollable electronic device  101  may receive a user input on at least one touch area among the plurality of touch areas  3512 , and may select at least one touch area (e.g.,  3531 ) corresponding to the at least one touch area (e.g.,  3532 ). 
     According to various embodiments, in operation  3405 , the rollable electronic device  101  may identify that the exposed area of the display is changed, and in operation  3406 , the rollable electronic device  101  may display the execution screen of at least one application corresponding to at least one object. For example, as illustrated in  3503  of  FIG.  35   , the rollable electronic device  101  may identify that a partial area  3510  of the display is exposed to the outside in the state in which one object (e.g.,  3531 ) is selected, and as illustrated in  3054  of  FIG.  35   , the rollable electronic device  101  may display the execution screen of an application corresponding to the selected one object. 
     According to various embodiments, when the two or more objects  3511  are selected, the rollable electronic device  101  may display the execution screens of applications corresponding to the two or more objects  3511  as in the above-described displaying forms (e.g., a multi-window form, a pop-up window form, or a form in which the multi-window form and the pop-up window form are combined) of the electronic device  101 . For example, the rollable electronic device  101  may identify the area change pattern of the display and may display the execution screens of applications in a displaying form corresponding to the identified area change pattern. As an example, the rollable electronic device  101  may display the execution screens of the applications in the multi-window form based on a change pattern of a trend in which the area of the display increases. As another example, the rollable electronic device  101  may display the execution screens of the applications in the pop-up window form based on a change pattern of a trend in which the area of the display increases, decreases, and then increases again. The area change pattern of the display is merely an example, and may be configured according to various change trends. 
     According to various embodiments, an out-folding electronic device  101  (e.g., an electronic device  101  having displays that are exposed to the outside (or respective surfaces of the displays are disposed opposite to each other) in the state in which the housings are in contact with each other as illustrated in  3701  of  FIG.  37   ) may switch the execution screen of the first application (e.g., a recent application) based on the angle between the housings. In-folding electronic device  101  may be defined as an electronic device  101  in which displays are in contact with (or face each other) in the state in which housings are in contact with each other, unlike the out-folding electronic device  101 . 
       FIG.  36    is a flowchart  3600  for describing other examples of operations of the electronic device  101  according to various embodiments. According to various embodiments, the operations illustrated in  FIG.  36    are not limited to the illustrated order, and may be performed in various orders. In addition, according to various embodiments, a greater or smaller number of operations compared to the operations illustrated in  FIG.  36    may be performed. A description is made with reference to  FIG.  37   . 
       FIG.  37    is a view for describing an example of an operation of switching the execution screen of a first application (e.g., a recent application) of an out-folding electronic device  101  according to various embodiments. 
     According to various embodiments, in operation  3601 , the out-folding electronic device  101  may display the execution screen of a first application including a plurality of first objects. For example, based on the angle between the housings being in a first angle range (e.g., 0 degrees) as illustrated in  3701  of  FIG.  37   , the out-folding electronic device  101  may display the execution screen of the first application (e.g., the recent application) in the area of the display corresponding to one housing (e.g., the first housing  3711 ). Since operation  3601  of displaying the execution screen of the recent application in the out-folding electronic device  101  may be performed like the above-described operation  801  of the electronic device  101 , a redundant description is omitted. 
     According to various embodiments, in operation  3602 , the out-folding electronic device  101  may identify that the folding angle is changed, and in operation  3603 , the out-folding electronic device  101  may configure touch areas in the second area while displaying, in the first area of the display, a plurality of second objects  3721  different from a plurality of first objects included in the execution screen of the first application. For example, as illustrated in  3702  of  FIG.  37   , the position of the second housing  3712 , which is in contact with the rear surface of the first housing  3711  of the out-folding electronic device  101 , may be changed toward the first housing  3711  according to the pivoting of the hinge. As the angle between the first housing  3711  and the second housing  3712  is changed, the out-folding electronic device  101  may identify the angle between the first housing  3711  and the second housing  3712  based on a value identified from a sensor. The out-folding electronic device  101  may change the execution screen of the recent application based on the identified angle corresponding to a second angle range (e.g., 120 degrees to 160 degrees). The out-folding electronic device  101  may change the sizes of the plurality of objects  3721  (e.g., icons and/or thumbnails) and may display the objects in the first area of the display corresponding to the hinge, and the out-folding electronic device  101  may configure a plurality of touch areas  3722  in a second area other than the first area. The first area may be an area adjacent to the hinge of the electronic device  101 . As illustrated in  3702  of  FIG.  37   , only objects of a single type (e.g., icons or thumbnails) may be displayed in the first area, or without being limited thereto, different types of objects (e.g., icons and thumbnails) may be displayed together in the first area, as described above. In addition, as illustrated in  3702  of  FIG.  37   , objects may be displayed and touch areas are displayed in an area of the display corresponding to one housing (e.g., the first housing  3711 ). Alternatively or additionally, without being limited thereto, objects may be displayed and touch areas may be configured in the two housings (e.g., the first housing  3711  and the second housing  3712 ). The description of the in-folding type electronic device  101  may be applicable to this case. 
     According to various embodiments, in operation  3604 , the out-folding electronic device  101  may receive an input for selecting at least one object among the plurality of objects  3721 . The electronic device  101  may receive a user input via the plurality of touch areas  3722  configured in the second area of the display corresponding to the first housing  3711  as illustrated in  3702  of  FIG.  37   , and may select an object corresponding to a touch area touched by the user input. 
     According to various embodiments, in operation  3605 , the out-folding electronic device  101  may identify that the folding angle is changed, and in operation  3606 , the out-folding electronic device  101  may display the execution screen of at least one application corresponding to at least one object. As illustrated in  3703  of  FIG.  37   , based on the changed folding angle corresponding to a third angle (e.g., 180 degrees), the electronic device  101  may execute an application corresponding to the selected object in a foreground mode, and may display the execution screen of the application. When the folding angle is changed and corresponds to the third angle range in the state in which the touch area is touched by the user input, the electronic device  101  may display the execution screen of the application corresponding to the object corresponding to the touch area. 
     According to various embodiments, as illustrated in  3704  and  3705  of  FIG.  37   , based on the folding angle corresponding to the second angle range again, the out-folding electronic device  101  may display the plurality of objects  3721  in the first area, and may display the plurality of touch areas  3722  in the second area. When one of the plurality of touch areas  3722  is selected, the out-folding electronic device  101  may identify the application corresponding to the selected touch area. Based on the folding angle being changed to correspond to the first angle range, the electronic device  101  may display the execution screen of the identified application in the area of the display corresponding to a housing (e.g., the first housing  3711  and/or the second housing  3712 ). For example, when the touch area is selected in the second area of the display corresponding to a housing (e.g., the first housing  3711 ), the electronic device  101  may display the execution screen of the area of the display corresponding to the housing (e.g., the first housing  3711 ). Without being limited thereto, when a touch area associated with one housing is selected, the out-folding electronic device  101  may display the touch area in the area of the display corresponding to the other housing. 
     According to various embodiments, when the two or more objects  3721  are selected, the out-folding electronic device  101  may display the execution screens of applications corresponding to the two or more objects  3721  as in the above-described displaying forms (e.g., a multi-window form, a pop-up window form, or a form in which the multi-window form and the pop-up window form are combined) of the electronic device  101 . For example, the out-folding electronic device  101  may identify the folding angle change pattern and may display the execution screens of applications in a displaying form corresponding to the identified folding angle change pattern. As an example, the rollable electronic device  101  may display the execution screens of the applications in the multi-window form based on a change pattern of a trend in which the folding angle decreases. As another example, the rollable electronic device  101  may display the execution screens of the applications in the pop-up window form based on a change pattern of a trend in which the folding angle increases and the decreases. The folding angle change pattern is merely an example, and may be configured according to various change trends.

Without being limited to those illustrated in  FIG.  39   , the first application may be an application including various types of contents (e.g., a web application and a call application). 
     According to various embodiments, when the folding angle is changed in operation  3802 , the electronic device may display a plurality of contents in the execution screen  4011  of the first application in operation  3803  and may configure touch areas  4222  for selecting the plurality of contents in a second area different from the first area  831 . For example, as illustrated in  3902  of  FIG.  39   , based on the angle (or the folding angle) between the housings  835  and  836  corresponding to a second angle range (e.g., 120 to 160 degrees), the electronic device may display the execution screen of a gallery application in which the thumbnails  4211  are arranged in the first area  831 . The electronic device may adjust the visual attributes (e.g., size) of the thumbnails  4211  to correspond to the area of the first area  831 , and may display, in the first area  831 , the thumbnails  4211  having the adjusted visual attributes (e.g., size). In addition, as illustrated in  3902  of  FIG.  39   , the electronic device may configure touch areas  4222  for selecting respective thumbnails  4211  in a second area, which is a remaining area other than the first area  831 . Since operation  3802  of the electronic device may be performed like the above-described operations  802  and  803  of the electronic device and the above-described operation  1304  of the electronic device, a redundant description is omitted. 
     According to various embodiments, in operation  3804 , the electronic device may receive an input on the first touch area  4311  among the plurality of touch areas  4222 . For example, when a user input is received on the first touch area  4311 , the electronic device may select a content corresponding to the first touch area  4311 . For example, when a user input is received on the first touch area  4311  as illustrated in  3903  of  FIG.  39   , the electronic device may select the first content (e.g., a first thumbnail). In addition, the electronic device may receive an input for selecting a plurality of contents through a plurality of touch areas  4222 . 
     According to various embodiments, when the folding angle is changed in operation  3805 , the electronic device may display a screen for a content corresponding to the first touch area  4311  in operation  3806 . For example, as illustrated in  3904  of  FIG.  39   , based on the angle (or the folding angle) between the housings  835  and  836  corresponding to a first angle range (e.g., 180 degrees), the electronic device may display the selected content in the entire screen  4041  of the display. For example, when at least two or more contents are selected, the electronic device may display two or more selected contents in a specific displaying form (e.g., a multi-window form, a pop-up window form, or a form in which the multi-window form and the pop-up window form are combined) based on a folding angle change pattern. Since the operation of displaying two or more contents in the electronic device may be performed as described above with reference to  FIGS.  26  to  30   , a redundant description is omitted.
