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 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 and 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 .

According to an embodiment, a geometric deformation event sensed by means of the sensor  420  by the electronic device  401  may occur as the shape or the structure of the electronic device  401  is changed and may include at least one of, for example, folding, unfolding, rotation, or a change in size of the display  410 . 
     For example, the sensor  420  may be at least one of a magnetic sensor including a hall sensor, a proximity sensor, an illumination sensor, a touch sensor, a gyro sensor, a bending sensor, an acceleration sensor, or an infrared sensor or a combination thereof. 
     According to an embodiment, the sensor  420  may be provided in a hinge structure (e.g., a hinge  223  of  FIG.  2   ) to sense a folding operation or an unfolding operation of the electronic device  401 . 
     According to an embodiment, the sensor  420  may sense rotation of the electronic device  401  based on a change in direction (e.g., landscape or portrait) where the electronic device  401  is placed. 
     According to an embodiment, when the display  410  may include a rollable display or a slidable display, the sensor  420  may sense a change in size of the display  410 . According to an embodiment, that the size of the display  410  is changed may refer, for example, to a display area of the display  410  being expanded or reduced. For example, for the rollable display, a magnetic substance may be provided in a cylindrical structure (e.g., a roll) which is an axis on which the display  410  is wound, and a magnetic sensor may be disposed on the display  220 . According to an embodiment, the electronic device  401  may detect a change in size of the display  410  based on the signal sensed by the magnetic sensor disposed on the display  410 . A description will be given of operations performed by the electronic device  401  as the sensor  420  of the electronic device  401  senses the change in size of the display  410  will be described below with reference to  FIG.  11   . 
     According to an embodiment, the processor  430  may be operatively connected with the display  410  and the sensor  420 . According an embodiment, the processor  430  may include various processing circuitry and process information or may control the sensor  420 , based on the signal sensed by the sensor  420 . According an embodiment, the processor  430  may output the processed information on the display  410 . According to an embodiment, the processor  430  may receive a user input, such as a touch input, by means of the display  410  (e.g., a touch screen display). 
     According to an embodiment, the processor  430  may obtain feature information of the display  410  based on the geometric deformation event sensed by the sensor  420 . The feature information of the display  410  may include at least one of, for example, a folding angle of the display  410 , a rotation state of the display  410 , a size of the display  410 , a horizontal length of the display  410 , a vertical length of the display  410 , or an aspect ratio of the display  410 . 
     For example, the processor  430  may identify a folding angle of the second display based on the signal sensed by the sensor  420 . According to an embodiment, the processor  430  may determine a folding state of the electronic device  401  based on the identified folding angle. The folding state may include, for example, a fully folded state shown in  FIG.  2   , a fully unfolded state shown in  FIG.  2   , and various flex modes shown in  FIG.  3   . According to an embodiment, the processor  430  may determine that the electronic device  401  is in a fully folded state (or a fully closed state) when the folding angle is 0 degree, may determine that the electronic device  401  is a fully unfolded state (or a fully open state) when the folding angle is 180 degrees, and may determine that the electronic device  401  is a flex mode (or a partially folded state) when the folding angle belongs to a specified range of greater than 0 degree and less than 180 degrees. 
     According to an embodiment, the processor  430  may determine to switch between the first display and the second display based on the folding angle. For example, the processor  430  may display content using the second display, when the folding angle is greater than or equal to a specified angle, and may display the content using the first display, when the folding angle is less than the specified angle. For example, the processor  430  may identify that it switches to the second display, when the folding angle is greater than or equal to the specified angle, and may identify that it switches to the first display, when the folding angle is less than the specified angle. Referring to  FIG.  3   , the processor  430  may identify the switching between the first display and the second display to identify that a flex mode of a first state  301  changes to a flex mode (a flex cover mode) of a second state  302  or a flex mode (or a flex tent mode) of a third state  303  or vice versa. 
     According to an embodiment, the processor  430  may identify a mounted state of the electronic device  401  based on the signal sensed by the sensor  420 . The processor  430  may identify whether the electronic device  401  is in, for example, a flex cover mode (the second state  302  of  FIG.  3   ) or a flex tent mode (a third state  303  of  FIG.  3   ). For example, when displaying a screen in a landscape mode, the processor  430  may invert and display a screen displayed on the first display depending on identifying that the flex cover mode changes to the flex tent mode or that the flex tent mode changes to the flex cover mode. 
     According to an embodiment, the processor  430  may identify a rotation state of the electronic device  401  based on the signal sensed by the sensor  420 . The rotation state may include, for example, a state where the width of the electronic device  401  is longer than its height and a state where the height of the electronic device  401  is longer than the width. According to an embodiment, the processor  430  may determine a display mode of the screen displayed on the display  410  by the electronic device  401  based on the identified rotation state. According to an embodiment, the display mode may refer to a setting of a direction in which the screen is displayed and may include, for example, a landscape mode in which the screen is displayed in a form where the horizontal length of the screen is longer than a vertical length thereof and a portrait mode in which the screen is displayed in a form where the vertical length of the screen is longer than the horizontal length. According an embodiment, the processor  430  may determine the display mode as the landscape mode to correspond to the rotation state of the electronic device  401 , when the rotation state of the electronic device  401  is a state where width is long, and may determine the display mode as the portrait mode to correspond to the rotation state of the electronic device  401 , when the rotation state of the electronic device  401  is a state where height is long. 
     According to an embodiment, the processor  430  may identify a setting of a rotation mode of the electronic device  401 . According to an embodiment, the setting of the rotation mode of the electronic device  401  may be a setting about whether to change the display mode of the electronic device  401  based on the rotation of the electronic device  401 , which is sensed by the sensor  420 . The setting of the rotation mode of the electronic device  401  may include, for example, an auto rotation mode for changing the display mode based on the rotation of the electronic device  401  and a portrait fixing mode for fixing the display mode to the portrait mode. 
     According to an embodiment, when the setting of the rotation mode of the electronic device  401  is the auto rotation mode, the processor  430  may change the display mode from the portrait mode to the landscape mode or from the landscape mode to the portrait mode in response to the rotation of the electronic device  401 , which is sensed by the sensor  420 . According to an embodiment, when the setting of the rotation mode of the electronic device  401  is the portrait fixing mode, the processor  430  may fix and set the display mode to only the portrait mode irrespective of the rotation of the electronic device  401 . For example, in the portrait fixing mode, the processor  430  may determine the display mode as the portrait mode even when the rotation state of the electronic device  401  is a state where width is longer than height. 
     As described above, the processor  430  may determine the display mode of the screen based on the setting of the rotation mode. According to various embodiments of the disclosure, the processor  430  may determine a display mode of the screen based on the display feature information and the setting of the rotation mode and may map the determined display mode to at least one application which is running According to various embodiments, the processor  430  may basically determine the display mode depending on the setting of the rotation mode, but may differently determine the display mode depending on identifying that the geometric state of the electronic device  401  is changed based on the display feature information (e.g., the folding angle). 
     For example, as the folding operation or the unfolding operation is sensed by the sensor  420 , the processor  430  may obtain a folding angle of the display  410 . As it is determined that the folding angle belongs to a specified range of greater than 0 degree and less than 180 degrees, the processor  430  may determine the display mode as the landscape mode. When the folding angle belongs to the specified range of greater than 0 degree and less than 180 degrees, the electronic device  401  may be in, for example, a flex mode shown in  FIG.  3   . According to an embodiment, when the electronic device  401  is folded or unfolded to change to the flex mode, the processor  430  may determine the display mode as the landscape mode. 
     According to an embodiment, when the screen rotation setting of the electronic device  401  is the portrait fixing mode, the processor  430  may display a screen in the portrait mode in the fully unfolded state or the fully folded state, but may change the display mode of the screen to the landscape mode depending on identifying that the fully unfolded state or the fully folded state changes to the flex mode. 
     According to an embodiment, when the screen rotation setting of the electronic device  401  is the portrait fixing mode, the processor  430  may determine the display mode as the portrait mode as it is determined that the folding angle deviates from the specified range of greater than 0 degree and less than 180 degrees. According an embodiment, when the electronic device  401  is folded or unfolded to release the flex mode, the processor  430  may change the display mode as the portrait mode. 
     According to an embodiment, when the screen rotation setting of the electronic device  401  is the auto rotation mode, the processor  430  may display the screen in a display mode determined based on a rotation state of the electronic device  401  in the fully unfolded state or the fully folded state, but may display the screen in the landscape mode irrespective of the rotation state of the electronic device  401  as it is identified that the fully unfolded state or the fully folded state changes to the flex mode. 
     According to an embodiment, when the screen rotation setting of the electronic device  401  is the portrait fixing mode, the processor  430  may determine the display mode based on the rotation state of the electronic device  401  as it is determined that the folding angle deviates from the specified range of greater than 0 degree and less than 180 degrees. According an embodiment, when the electronic device  401  is folded or unfolded to release the flex mode, the processor  430  may determine the display mode based on the rotation state. For example, the processor  430  may display the screen in the landscape mode, when the flex mode is released and the rotation state of the electronic device  401  is a state where width is longer than height, and may display the screen in the portrait mode, when the flex mode is released and the rotation state of the electronic device  401  is a state where height is longer than width. 
     According to an embodiment, the processor  430  may perform a mapping operation of applying the determined display mode (e.g., the landscape mode or the portrait mode) of the screen to a screen displayed on the display  410 . For example, the processor  430  may resize the screen displayed on the display  410  depending on the determined display mode of the screen. According to an embodiment, the processor  430  may display the resized screen on the display  410  depending on the mapped display mode. 
     According to an embodiment, the screen displayed on the display  410  by the electronic device  401  may be, but is not limited to, an execution screen of at least one application stored in a memory  440  to be described below, which may further include at least one of, for example, a home screen, a lock screen, or an always on display (AOD) screen. 
     According to an embodiment, the processor  430  may determine a display mode of at least one of an execution screen of at least one application, a home screen, a lock screen, an AOD screen, or a voice call screen as the landscape mode as it is determined that the folding angle belongs to the specified range of greater than 0 degree and less than 180 degrees. 
     According to an embodiment, the memory  440  may be operatively connected with the processor  430 . The memory  440  may store one or more instructions causing the processor  430  to perform the above-mentioned operations. According to an embodiment, the memory  440  may store at least one application run by the processor  430 . 
     According to various embodiments of the disclosure, the electronic device  401  may change the display mode of the screen to the landscape mode or the portrait mode in response to a geometric deformation event (e.g., folding, unfolding, or a change in size of the display  410 ) of the electronic device  401  to provide a screen optimized for a specified geometric state of the electronic device  401 , thus improving user experience.

       FIG.  6    is a flowchart  600  illustrating an example operation of an electronic device according to an embodiment. Operations of an electronic device (e.g., an electronic device  401  of  FIG.  4   ), which will be described below, may be performed by a processor (e.g., a processor  430  of  FIG.  4   ) of an electronic device (e.g., an electronic device  401  of  FIG.  4   ). 
     In operation  601 , the electronic device may display an execution screen of at least one application stored in a memory (e.g., a memory  440  of  FIG.  4   ) on a display (e.g., a display  410  of  FIG.  4   ).

     According to an embodiment, the electronic device may store the setting of the rotation mode of the electronic device. For example, the electronic device may store state information of the electronic device, which is about whether it is in the auto rotation mode or the portrait fixing mode. For example, the electronic device may store state information of the electronic device, which is about whether the rotation state of the electronic device is a state where width is longer than height or a state where height is longer than width in a first state before a geometric deformation event occurs. 
     In operation  603 , the electronic device may obtain display feature information in response to occurrence of the geometric deformation event of the electronic device. According to an embodiment, the geometric deformation event may include at least one of folding, unfolding, rotation, or a change in size of the display.

     For example, an electronic device including a foldable display may obtain folding angle information depending on detecting a folding operation or an unfolding operation by means of the sensor. According to an embodiment, a foldable electronic device  201  shown in  FIGS.  2  and  3   , may further obtain switching information between a first display  211  (an external display) and a second display  212  (an internal display) based on the folding angle information. For example, the electronic device  201  may identify that it switches to the second display  212 , when the folding angle is greater than or equal to a specified angle, and may identify that it switches to the first display  211 , when the folding angle is less than the specified angle. 
     For another example, an electronic device including a rollable display or a slidable display may obtain size information of the display depending on detecting a change in size of the display by means of the sensor. 
     According to an embodiment, the electronic device may detect rotation of the electronic device by means of the sensor. For example, the electronic device may change the display mode of the screen to the landscape mode depending on detecting rotation from a state where width is longer than height to a state where the height is longer than the width in the auto rotation mode and may change the display mode of the screen to the portrait mode depending on detecting rotation from the state where the height is longer than the width to the state where the width is longer than the height. 
     In operation  604 , the electronic device may determine and map a display mode of the execution screen of the at least one application based on the display feature information and the setting of the rotation mode. For example, the electronic device may identify a folding state based on the folding angle. For example, when the folding angle belongs to a specified range of greater than 0 degree and less than 180 degrees, the electronic device may identify whether the electronic device is in a flex mode. According to an embodiment, the folding state of the electronic device, such as the flex mode, may be included in the display feature information. According to an embodiment, the electronic device may determine the display mode of the execution screen of the at least one application as the landscape mode depending on identifying that the electronic device is in the flex mode. 
     For another example, when the folding angle deviates from the specified range of greater than 0 degree and less than 180 degrees, the electronic device may identify whether the flex mode of the electronic device is released. According to an embodiment, that the flex mode of the electronic device is released may refer, for example, to the electronic device changing to a fully unfolded state or a fully folded state. According to an embodiment, the electronic device may determine the display mode of the execution screen of the at least one application based on the rotation mode setting depending on identifying that the flex mode of the electronic device is released. For example, the electronic device may determine the display mode of the execution screen of the at least one application as the portrait mode, when the flex mode of the electronic device is released in the portrait fixing mode, and may determine the display mode of the execution screen of the at least one application as the landscape mode or the portrait mode depending on the rotation state of the electronic device, when the flex mode of the electronic device is released in the auto rotation mode. 
     According to an embodiment, the electronic device may map the determined display mode to the at least one application. For example, the electronic device may determine state information of the at least one application to display a screen in the landscape mode when the electronic device is in the flex mode. 
     In operation  605 , the electronic device may display the display mode of the execution screen of the at least one application on the display depending (e.g., based) on the mapped display mode. For example, when the electronic device is in the flex mode, it may display the execution screen of the at least one application, which is displayed on the display, in the landscape mode. 
     The method for controlling the display mode of the execution screen in response to the geometric deformation when the electronic device displays the execution screen of the at least one application is described in the above embodiment, but not limited thereto. Even when displaying a home screen, the lock screen, an AOD screen, or a voice call screen, the electronic device may control a display mode of each screen in response to geometric deformation. 
     Hereinafter, a description will be given by comparing a conventional electronic device with an electronic device according to an example embodiment with reference to  FIGS.  7 A,  7 B,  7 C,  7 D and  7 E .

For example, that the electronic device  910  changes to the third state  903  may refer, for example, to the electronic device  910  being restored to the first state  901 . 
     In the third state  903 , the electronic device  910  may determine that the first condition that “the electronic device  910  is in the flex mode” is released. According to an embodiment, as the first condition is released, the electronic device  910  may restore the electronic device  910  to the first state  901  based on the state information of the electronic device  910 , which is stored in the first state  901 .

     According to an embodiment, as the electronic device  910  is unfolded over the specified angle in the second state  922 , it may identify that the display displaying content switches from a first display  911  to a second display  912 . In third second state  923 , the electronic device  910  may determine that a second condition that “the electronic device  910  is the flex mode and the second display  912  is enabled” is met. According to an embodiment, when the second condition is met, the electronic device  910  may determine that the first condition is also met. According to an embodiment, as the second condition is met, the electronic device  910  may execute a first operation of the second condition, which sets the display mode of the screen to the flex mode. As the first operation of the second condition is executed, the electronic device  910  may display an execution screen  9010 ″ of the application in the flex mode. According to an embodiment, when the folding angle of the electronic device  910  is a specified angle range (e.g., 80 degrees to 130 degrees), the flex mode may refer to a mode for providing a UI optimized the flex mode where the electronic device  910  displays content using the second display  912 . For example, the electronic device  910  may play a video on the display area of the erected second display  912  and may display a UI for controlling the playback of the video on the display area of the lying second display  912 . 
     According to an embodiment, as the electronic device  910  is unfolded in the third state  923 , it may change to a fully unfolded state in a fourth state  924 . In the fourth state  924 , the electronic device  910  may determine that the first condition that “the electronic device  910  is in the flex mode” is released. According to an embodiment, when the first condition is released, the electronic device  910  may determine that the second condition is also released. According to an embodiment, as the first condition is released, the electronic device  910  may restore the electronic device  910  to the first state  921  based on the state information of the electronic device  910 , which is stored in the first state  921 . For example, the electronic device  910  may change the setting of the rotation mode to the portrait fixing mode and may display the execution screen  9010  of the application in the portrait mode. 
     Referring to  FIG.  9 C , in a first state  941 , the electronic device  910  may be in a fully unfolded state. According to an embodiment, a setting of a rotation mode of the electronic device  910  may be the portrait fixing mode. According to an embodiment, the electronic device  910  may display an execution screen  9010  of an application (e.g., a video playback application) on a second display  912 . According to an embodiment, as the setting of the rotation mode of the electronic device  910  is the portrait fixing mode, the electronic device  910  may display the execution screen  9010  of the application on the second display  912  in the portrait mode. According to an embodiment, the electronic device  910  may store state information of the electronic device  910  in the first state  901 . For example, the electronic device  910  may store state information that the setting of the rotation mode of the electronic device  910  is the portrait fixing mode. 
     According to an embodiment, as the electronic device  910  is folded in the first state  941 , it may change to a flex mode in a second state  942 . In the second state  922 , the electronic device  910  may determine that a second condition that “the electronic device  910  is the flex mode and the second display  912  is enabled” is met. According to an embodiment, when the second condition is met, the electronic device  910  may determine that the first condition is also met. According to an embodiment, as the second condition is met, the electronic device  910  may execute a first operation of the second condition, which sets the display mode of the screen to the flex mode.

According to an embodiment, as the second condition is released, the electronic device  910  may restore the electronic device  910  to the first state  941  based on the state information of the electronic device  910 , which is stored in the first state  941 . For example, the electronic device  910  may change the setting of the rotation mode to the portrait fixing mode and may display the execution screen  9010  of the application in the portrait mode. 
     Hereinafter, a description will be given of a method for changing a display mode of a screen in response to geometric deformation while an electronic device displays execution screens of a plurality of applications in a multi-window mode according to various embodiments with reference to  FIG.  10   . 
       FIG.  10    is a diagram  1000  illustrating an example operation of an electronic device in a multi-window mode according to an embodiment. Operations of an electronic device  1001  (e.g., an electronic device  401  of  FIG.  4   ), which will be described below, may be performed by a processor (e.g., a processor  430  of  FIG.  4   ) of the electronic device  1001 . The electronic device  1001  according to an embodiment, which will be described below, may have a form factor of a foldable electronic device  201  shown in  FIGS.  2  and  3   . 
     Referring to  FIG.  10   , the electronic device  1001  may display execution screens of a plurality of applications in the multi-window mode on a second display  1011 . For example, the electronic device  1001  may configure a multi-window layout including a first window  1051 , a second window  1052 , a third window  1053 , and a fourth window  1054  in which the full screen is split into four and a fifth window  1055  which is one pop-up window and may map each of the plurality of applications to each window to display the execution screens of the plurality of applications in the multi-window mode. 
     As the electronic device  1001  determines that the folding angle belongs to a specified range of greater than 0 degree and less than 180 degrees, it may determine display modes of the plurality windows as a landscape mode. According to an embodiment, the electronic device  1001  may reconfigure the first window  1051 , the second window  1052 , the third window  1053 , the fourth window  1054 , and the fifth window  1055  at a size of the display in the landscape mode or a size optimized for an aspect ratio of the display depending on identifying that the electronic device  1001  changes to the flex mode. 
     According to an embodiment, as the electronic device  1001  changes to the flex mode, it may display the execution screens of the plurality of applications in the multi-window mode depending on a multi-window layout including the reconfigured first window  1051 ′, the reconfigured second window  1052 ′, the reconfigured third window  1053 ′, the reconfigured fourth window  1054 ′, and the reconfigured fifth window  1055 ′. 
     According to an embodiment, as the electronic device  1001  changes to the flex mode, it may change the display modes of the plurality of windows making up the multi-window mode to the landscape mode, thus removing the inconvenience of having to separately change the setting of the rotation mode of each of the execution screens of the plurality of applications to the landscape mode in the multi-window mode. 
     Hereinafter, a description will be given of a method for changing a display mode of a screen in response to geometric deformation when an electronic device includes a rollable display according to various embodiments with reference to  FIG.  11   . 
       FIG.  11    is a diagram  1100  illustrating an example operation of an electronic device, including a rollable display according to various embodiments. Operations of an electronic device  1101  (e.g., an electronic device  401  of  FIG.  4   ), which will be described below, may be performed by a processor (e.g., a processor  430  of  FIG.  4   ) of the electronic device  1101 . 
     According to an embodiment, the electronic device  1101  may include a first housing  1141 , a second housing  1142 , and a display  1150 . According to an embodiment, the display  1150  may be a rollable display. According to an embodiment, the display  1150  or a display area of the display  1150  may be expanded in size as the distance between the first housing  1141  and the second housing  1142  increases, and the display  1150  or the display area of the display  1150  may be reduced in size as the distance between the first housing  1141  and the second housing  1142  decreases. 
     According to an embodiment, the electronic device  1101  may detect that the size of the display  1150  changes as the distance between the first housing  1141  and the second housing  1142  increases by means of a sensor (e.g., a sensor  420  of  FIG.  4   ). The electronic device  1101  may obtain an aspect ratio of the display  1150  depending on detecting that the size of the display  1150  changes. 
     According to an embodiment, as it is determined that the aspect ratio (landscape/portrait) is greater than or equal to a threshold, the electronic device  1101  may determine a display mode of an execution screen of at least one application, which is displayed on the display  1150 , as a landscape mode and may map the determined display mode to the at least one application. 
     According to an embodiment, the electronic device  1101  may display the execution screen of the at least one application on the display  1150  in the landscape mode. 
     In a first state  1110 , the distance between the first housing  1141  and the second housing  1142  of the electronic device  1101  may be less than a threshold distance for enabling the display  1150 . 
     In a second state  1120 , as the distance between the first housing  1141  and the second housing  1142  of the electronic device  1101  is greater than or equal to the threshold distance for enabling the display  1150 , the display  1150  may be enabled. According to an embodiment, the electronic device  1101  may display an execution screen  1051  of the at least one application on the display  1150 . 
     According to an embodiment, the aspect ratio (e.g., landscape/portrait) of the display  1150  in the second state  1120  may be less than the threshold. As the aspect ratio (e.g., landscape/portrait) of the display  1150  is less than the threshold, the electronic device  1101  may display the execution screen  1051  of the at least one application in a portrait mode. 
     The distance between the first housing  1141  and the second housing  1142  of the electronic device  1101  in the third state  1130  may be longer than the distance between the first housing  1141  and the second housing  1142  of the electronic device  1101  in the second state  1120 . According to an embodiment, the aspect ratio (e.g., landscape/portrait) of the display  1150  in the third state  1130  may be greater than or equal to the threshold. As the aspect ratio (e.g., landscape/portrait) of the display  1150  is greater than or equal to the threshold, the electronic device  1101  may display an execution screen  1051 ′ of the at least one application in the landscape mode. 
     Because a conventional electronic device does not control a display mode of a screen in response to a change in size of the display  1150 , the electronic device  1101  has a problem where it does not provide a screen optimized according a variable size of the display  1150 , because it is able to display the execution screen of the application in only the portrait mode corresponding to the first area  1152  although it changes to the third state  1130 . 
     According to an embodiment, the electronic device  1101  may obtain aspect ratio information of the display  1150  in response to the change in size of the display  1150  and may automatically change the display mode of the screen displayed on the display  1150  to the landscape mode without a separate user input as it is determined that the aspect ratio of the display  1150  is greater than or equal to the threshold, thus improving user experience. 
     According to an example embodiment, an electronic device (e.g., an electronic device  101  of  FIG.  1   , an electronic device  201  of  FIGS.  2  and  3   , an electronic device  401  of  FIG.  4   , an electronic device  702  of  FIGS.  7 A to  7 E , an electronic device  910  of  FIGS.  9 A to  9 C , an electronic device  1001  of  FIG.  10   , or an electronic device  1101  of  FIG.  11   ) may include: a display (e.g., a display module  160  of  FIG.  1   , a first display  211  of  FIGS.  2  and  3   , a second display  212  of  FIGS.  2  and  3   , a display  410  of  FIG.  4   , a first display  721  of  FIGS.  7 A to  7 E , a second display  722  of  FIGS.  7 A to  7 E , a first display  911  of  FIGS.  9 A to  9 C , a second display  912  of  FIGS.  9 A to  9 C , a first display  1011  of  FIG.  10   , a second display  1012  of  FIG.  10   , or a display  1150  of  FIG.  11   ), a sensor (e.g., a sensor module  176  of  FIG.  1    or a sensor  420  of  FIG.  4   ) configured to sense geometric deformation of the electronic device, at least one processor (e.g., a processor  120  of  FIG.  1    or a processor  430  of  FIG.  4   ), and a memory (e.g., a memory  130  of  FIG.  1    or a memory  410  of  FIG.  4   ) operatively connected with the at least one processor and including at least one application.
