Referring to FIG. 1, the electronic device 101 in the network environment 100 may communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or at least one of an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the connecting terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In some embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).
The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to one embodiment, as at least part of the data processing or computation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134. According to an embodiment, the processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)), or an auxiliary processor 123 (e.g., a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operable independently from, or in conjunction with, the main processor 121. For example, when the electronic device 101 includes the main processor 121 and the auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be specific to a specified function. The auxiliary processor 123 may be implemented as separate from, or as part of the main processor 121.
The auxiliary processor 123 may control at least some of functions or states related to at least one component (e.g., the display module 160, the sensor module 176, or the communication module 190) among the components of the electronic device 101, instead of the main processor 121 while the main processor 121 is in an inactive (e.g., sleep) state, or together with the main processor 121 while the main processor 121 is in an active state (e.g., executing an application). According to an embodiment, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., the camera module 180 or the communication module 190) functionally related to the auxiliary processor 123. According to an embodiment, the auxiliary processor 123 (e.g., the neural processing unit) may include a hardware structure specified for artificial intelligence model processing. An artificial intelligence model may be generated by machine learning. Such learning may be performed, e.g., by the electronic device 101 where the artificial intelligence is performed or via a separate server (e.g., the server 108). Learning algorithms may include, but are not limited to, e.g., supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning.

The speaker may be used for general purposes, such as playing multimedia or playing record. The receiver may be used for receiving incoming calls. According to an embodiment, the receiver may be implemented as separate from, or as part of the speaker.
The display module 160 may visually provide information to the outside (e.g., a user) of the electronic device 101. The display module 160 may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. According to an embodiment, the display module 160 may include a touch sensor adapted to detect a touch, or a pressure sensor adapted to measure the intensity of force incurred by the touch.
The audio module 170 may convert a sound into an electrical signal and vice versa.

The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.
The interface 177 may support one or more specified protocols to be used for the electronic device 101 to be coupled with the external electronic device (e.g., the electronic device 102) directly (e.g., wiredly) or wirelessly. According to an embodiment, the interface 177 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.
A connecting terminal 178 may include a connector via which the electronic device 101 may be physically connected with the external electronic device (e.g., the electronic device 102). According to an embodiment, the connecting terminal 178 may include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector).
The haptic module 179 may convert an electrical signal into a mechanical stimulus (e.g., a vibration or a movement) or electrical stimulus which may be recognized by a user via his tactile sensation or kinesthetic sensation. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electric stimulator.
The camera module 180 may capture a still image or moving images. According to an embodiment, the camera module 180 may include one or more lenses, image sensors, image signal processors, or flashes.
The power management module 188 may manage power supplied to the electronic device 101. According to one embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).
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 via the first network 198 (e.g., a short-range communication network, such as BluetoothTM, 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.
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 (e.g., the wireless communication module 192) 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, a 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 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. The electronic device 101 may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a”. “an.” “the,” and “at least one” do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. For example, “an element” has the same meaning as “at least one element,” unless the context clearly indicates otherwise.
It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.
Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.
FIG. 2A is a diagram illustrating an electronic device 200 in an unfolded state according to various embodiments. FIG. 2B is a diagram illustrating the electronic device 200 shown in FIG. 2A in a folded state.
Referring to FIGS. 2A and 2B, an embodiment of an electronic device 200 may include a pair of housings 210 and 220 (e.g., foldable housings) rotatably combined with each other based on a folding axis A1 through a hinge device (e.g., a hinge device 264 of FIG. 3) to be folded with the folding axis A1, a first display 230 (e.g., a flexible display, a foldable display, and/or a main display) disposed in the pair of housings 210 and 220, and a second display 251 (e.g., sub-display). According to an embodiment, the hinge device (e.g., the hinge device 264 of FIG. 3) may be disposed not to be seen from an outside through the first housing 210 and the second housing 220 in a folded state, and may be disposed not to be seen from the outside through a hinge cover 265 protecting the hinge device and covering a foldable part in an unfolded state. Herein, a side on which the first display 230 is disposed may be defined as a front side of the electronic device 200, and an opposite side of the front side may be defined as a rear side of the electronic device 200. Further, a side surrounding a space between the front side and the rear side may be defined as a lateral side of the electronic device 200.
According to various embodiments, the pair of housings 210 and 220 may include the first housing 210 and the second housing 220 foldably disposed to each other through the hinge device (e.g., the hinge device 264 of FIG. 3). According to an embodiment, the pair of housings 210 and 220 may not be limited to the shape and combination as illustrated in FIGS. 2A and 2B, and may be variously modified to be implemented by a different shape or part combinations and/or association. According to an embodiment, the first housing 210 and the second housing 220 may be disposed on opposing sides around the folding axis A1, and may have a symmetric shape as a whole about the folding axis A1. According to a certain embodiment, for example, the first housing 210 and the second housing 220 may be asymmetrically folded based on the folding axis A1. According to an embodiment, angles or distances between the first housing 210 and the second housing 220 may change depending on whether the electronic device 200 is in an unfolded state, a folded state, or an intermediate state.
According to various embodiments, when the electronic device 200 is in the unfolded state, the first housing 210 may be connected to the hinge device (e.g., hinge device 264 of FIG. 3), and may include a first side 211 disposed to be directed toward the front side of the electronic device 200, a second side 212 directed toward an opposite direction of the first side 211, and a first side member 213 surrounding at least a part of a first space between the first side 211 and the second side 212. According to an embodiment, the second housing 220 may be connected to the hinge device (e.g., hinge device 264 of FIG. 3) in the unfolded state of the electronic device 200, and may include a third side 221 disposed to be directed toward the front side of the electronic device 200, a fourth side 222 directed toward an opposite direction of the third side 221, and a second side member 223 surrounding at least a part of a second space between the third side 221 and the fourth side 222. According to an embodiment, the first side 211 may be directed in a same direction as that of the third side 221 in the unfolded state, and may face the third side 221 in the folded state. According to an embodiment, the electronic device 200 may include a recess 201 defined through structural combination of the first housing 210 and the second housing 220 to accommodate the first display 230. According to an embodiment, the recess 201 may have substantially a same size as that of the first display 230.
According to various embodiments, the hinge cover 265 may be disposed between the first housing 210 and the second housing 220 to cover the hinge device (e.g., hinge device 264 of FIG. 3). According to an embodiment, the hinge cover 265 may be hidden or exposed to an outside by parts of the first housing 210 and the second housing 220 depending on the unfolded state, the folded state, or the intermediate state of the electronic device 200. In an embodiment, for example, in the unfolded state of the electronic device 200, the hinge cover 265 may be hidden by the first housing 210 and the second housing 220, and may not be exposed. According to an embodiment, in case that the electronic device 200 is in the folded state, the hinge cover 265 may be exposed to the outside between the first housing 210 and the second housing 220. According to an embodiment, when the electronic device 200 is in the intermediate state where the first housing 210 and the second housing 220 are folded with a certain angle, the hinge cover 265 may be at least partly exposed to the outside of the electronic device 200 between the first housing 210 and the second housing 220. In an embodiment, for example, an area in which the hinge cover 265 is exposed to the outside may be smaller than that in a completely folded state. According to an embodiment, the hinge cover 265 may include a curved side.
According to various embodiments, when the electronic device 200 is in the unfolded state (e.g., state of FIG. 2A), the first housing 210 and the second housing 220 form an angle of about 280 degrees, and a first area 230a, a folding area 230c, and a second area 230b of the first display 230 may be disposed to form a plane and to be directed in a same direction as each other.

The flexible connection part 451 may be bent according to the rotation of the second housing 220 relative to the first housing 210. Referring to FIG. 4C, the flexible connection part 451 may include a portion in which a plurality of grooves 451-1 are formed. When the second housing 220 rotates relative to the first housing 210, deformation occurs in the portion in which the plurality of grooves 451-1 are formed so that the first support part 450 may be bent. In an embodiment, for example, the plurality of grooves 451-1 may be arranged in a lattice form. The shape of an embodiment of the flexible connection part 451 is illustrated in FIG. 4C, and alternatively, another structure for bending of the first support part 450 may be included in the first support part 450. In an embodiment, the first support part 450 may include a film including or made of glass or synthetic resin material.
According to various embodiments, the recognition member 460 may be disposed under the first support part 450 (e.g., in the −Z-axis direction). The recognition member 460 may recognize a pen input device approaching the display module 400, and may generate a signal corresponding to a coordinate value of the pen input device as the pen input device moves on the display module 400. In such an embodiment where the recognition member 460 is included in the display module 400, the display module 400 may recognize an input made via the pen input device. In an embodiment, for example, the recognition member 460 may include a conductive layer in which a plurality of conductive lines are formed or defined. A magnetic field may be formed by an AC voltage applied to the conductive layer. As a pen input device having a coil embedded therein approaches, a current flows through an internal circuit of the pen input device due to electromagnetic induction to form a resonance frequency, and the recognition member 460 recognizes the resonance frequency to recognize the movement of the pen input device. The principle of the recognition member 460 recognizing the pen input device as described above is merely an example, and the recognition member 460 may recognize the movement of the pen input device in various ways.
In an embodiment, the recognition member 460 may include a first recognition member 460A and a second recognition member 460B, as illustrated in FIG. 4B. In an embodiment, for example, the first recognition member 460A may be disposed in the first housing 210, and the second recognition member 460B may be disposed in the second housing 220. The first recognition member 460A may correspond to the first area 440A of the display panel 440, and the second recognition member 460B may correspond to the second area 440B of the display panel 440. The input of the pen input device via the first area 440A may be recognized via the first recognition member 460A, and the input of the pen input device via the second area 440B may be recognized through the second recognition member 460B.
According to various embodiments, the first recognition member connection part 461A may electrically connect the first recognition member 460A to the first printed circuit board 510A of the printed circuit board 510. The first recognition member connection part 461A may be electrically connected, at one end thereof, to the first recognition member 460A and may be electrically connected, at the other end thereof, to the first printed circuit board 510A disposed in the first housing 210 by passing through the side surfaces of the components (e.g., the second support part 470 in FIG. 4B) disposed under the first recognition member 460A (e.g., in the −Z-axis direction). A signal generated by the first recognition member 460A may be transmitted to the first printed circuit board 510A via the first recognition member connection part 461A. The first recognition member connection part 461A may pass through the space between a side surface of the display module 400 and the first housing 210 to electrically connect the first printed circuit board 510A disposed under the first recognition member 460A and the first recognition member 460A to each other. In such an embodiment, since the first recognition member connection part 461A extends by sharing the side surfaces of the layers disposed under the first recognition member 460A, holes may be omitted from the components disposed under the first recognition member 460A.
According to various embodiments, the second recognition member connection part 461B may electrically connect the second recognition member 460B to the second printed circuit board 510B. The second recognition member connection part 461B may be electrically connected, at one end thereof, to the second recognition member 460B and may be electrically connected, at the other end thereof, to the second printed circuit board 510B disposed in the second housing 220 by passing through the side surfaces of the components (e.g., the second support part 470 in FIG. 4B) disposed under the second recognition member 460B. A signal generated by the second recognition member 460B may be transmitted to the second printed circuit board 510B via the second recognition member connection part 461B. The second recognition member connection part 461B may pass through the space between a side surface of the display module 400 and the second housing 220 to electrically connect the second printed circuit board 510B disposed under the second recognition member 460B and the second recognition member 460B to each other. In such an embodiment, since the second recognition member connection part 461B extends by sharing the side surfaces of the layers disposed under the second recognition member 460B, holes may be omitted from the components disposed under the second recognition member 460B.
According to various embodiments, the second support part 470 may be disposed under the recognition member 460 to support the recognition member 460. In an embodiment, for example, the second support part 470 may include a first portion 740A disposed in the first housing 210 to support the first recognition member 460A and a second portion 470B disposed in the second housing 220 to support the second recognition member 460B. The second support part 470 may be formed in a plate shape. The second support part 470 may include a conductive material to perform a grounding or shielding function for the display module 400.
According to various embodiments, a first bracket 261 (e.g., the first support member 261 in FIG. 3) may be disposed in the first housing 210. A second bracket 262 (e.g., the second support member 262 in FIG. 3) may be disposed in the second housing 220. The first bracket 261 may support at least some of various components disposed in the first housing 210. In an embodiment, the first bracket 261 may be integrally formed with the first housing 210 as a single unitary body. The second bracket 262 may support at least some of various components disposed in the second housing 220. In an embodiment, the second bracket 262 may be integrally formed with the second housing 220 as a single unitary body.
An electrical signal or electrical interference not related to the operation of the display module 400 may affect the operation of the display module 400. For example, electric charges accumulated in a specific portion of the display module 400 may cause a flicker phenomenon in which the display intermittently flickers. In an embodiment, the display module 400 is desired to be connected to a ground to remove such undesired charges. In the display module 400 according to various embodiments disclosed herein, the second support part 470 may include a conductive material electrically connected to the second printed circuit board 510B to ground the display module 400. Since the second support part 470 is electrically connected to the second printed circuit board 510B, abnormal charges that prevent the normal operation of the display module 400 may be removed via the second support part 470. In an embodiment, for example, the second support part 470 may be electrically connected to a ground included in the second printed circuit board 510B.
According to various embodiments, the first portion 470A of the second support part 470 may be disposed in the first housing 210 to be electrically connected to the connection part 490, which electrically connects the display panel 440 and the first printed circuit board 510A to each other. In such an embodiment where the first portion 470A is electrically connected to the connection part 490, the first portion 470A and the first printed circuit board 510A may be electrically connected to each other. Thus, the first portion 470A of the second support part 470 may be electrically connected to the ground of the first printed circuit board 510A. Referring to FIG. 4B, the first portion 470A and the connection part 490 may be electrically connected to each other by the first contact part 480A disposed between the first portion 470A and the connection part 490. The first contact part 480A may include, for example, a conductive material. In an embodiment, at least a portion of the first contact part 480A may include an adhesive material such as a conductive tape.
According to various embodiments, the second portion 470B of the second support part 470 may be electrically connected to the second recognition member connection part 461B, which electrically connects the second recognition member 460B to the second printed circuit board 510B. Since the second portion 470B is electrically connected to the second recognition member connection part 461B, the second portion 470B may be electrically connected to the ground of the second printed circuit board 510B. The second portion 470B and the second recognition member connection part 461B may be electrically connected to each other by the second contact part 480B disposed between the second portion 470B and the second recognition member connection part 461B. The second contact part 480B may include, for example, a conductive material. In another embodiment, the second contact part 480B may include an elastic material to withstand deformation due to an external force. In an embodiment, as illustrated in FIG. 4B, the second portion 470B is electrically connected to the second recognition member connection part 461B, but the deformation of the surface shape of the display module 400 may be reduced since the second contact part 480B, which include or is formed of an elastic material, may be restored even if it is deformed by an external force.
Referring to FIG. 4B, the second bracket 262 may be disposed under the second portion 470B (e.g., in the −Z direction in FIG. 4B) to support the second portion 470B. In an embodiment, the second contact part 480B may be disposed in a recess 262-1 formed in the second bracket 262. The recess 262-1 may be a groove formed in the second bracket 262 in the −Z direction with reference to FIG. 4B. Since the second contact part 480B is disposed in the recess 262-1 in the second bracket 262, deformation of a portion of the second portion 470B that faces the second contact part 480B may be reduced due to the volume of the second contact part 480B itself. Accordingly, deformation of the surface shape of the display module 400 supported by the second portion 470B may also be reduced.
In various embodiments, since the second portion 470B is electrically connected to the second printed circuit board 510B via the second recognition member connection part 461B for connecting the second recognition member 460B and the second printed circuit board 510B to each other, a separate component or space for electrically connecting the second portion 470B to the second printed circuit board 510B may be omitted.
FIG. 5A is a schematic cross-sectional view of the second recognition member connection part 461B and peripheral components thereof taken along line P2-P2 in FIG. 4A. FIG. 5B is a view for describing a layer structure of the second recognition member connection part 461B according to various embodiments disclosed herein.
According to various embodiments, as illustrated in FIG. 5A, the second portion 470B of the second support part (e.g., the second support part 470 in FIGS. 4A and 4B) may be disposed between the second recognition member 460B and the second recognition member connection part 461B. The second portion 470B and the second recognition member connection part 461B may be electrically connected to each other by the first contact part 480 disposed between the second recognition member connection part 461B and the second portion 470B. Since the second portion 470B is electrically connected to the second recognition member connection part 461B by the first contact part 480 and the second recognition member connection part 461B is electrically connected to the second printed circuit board 510B, the second portion 470B and the second printed circuit board 510B can be electrically connected to each other.
Referring to FIGS. 5A and 5B, the second recognition member connection part 461B, which is in contact with the second portion 470B, may include a plurality of layers. In an embodiment, for example, the second recognition member connection part 461B may include a first layer 520 and a second layer 530. The first layer 520 may be stacked on the second layer 530 as illustrated in FIG. 5A, and another layer may be disposed between the first layer 520 and the second layer 530. In an embodiment, the first layer 520 may include a first zone 521 in which a wiring line 581 for connection to the second recognition member 460B is disposed and a second zone 522 in which a wiring line 584 for connection to the second contact part 480B is disposed. In an embodiment, the second contact part 480B may be disposed between the second zone 522 and the second portion 470B of the first layer 520. The second contact part 480B may electrically connect the wiring line 584 disposed in the second zone 522 of the first layer 520 and the second portion 470B to each other. An insulating layer 540 may be disposed between the first zone 521 and the second portion 470B of the first layer 520. A wiring line 581 for transmitting a signal of the second recognition member 460B may be disposed in the first zone 521 of the first layer 520. The insulating layer 540 disposed between the first zone 521 of the first layer 520 and the second portion 470B may block movement of an electrical signal of the second portion 470B to the first zone 521. Since the second portion 470B and the first zone 521 of the first layer 520 are electrically cut off or insulated by the insulating layer 540, the wiring line 581 disposed in the first zone 521 may transmit the signal of the second recognition member 460B to the second printed circuit board 510B without being affected by the second portion 470B.
According to various embodiments, a wiring line 583 for transmitting a signal of the second recognition member 460B may be disposed on the second layer 530 of the second recognition member connection part 461B. In an embodiment, the second layer 530 may be disposed to be in contact with the first zone 521 and the second zone 522 of the first layer 520. A wiring line 583 for transmitting a signal of the second recognition member 460B may be disposed on the second layer 530. The wiring line 581 disposed in the first zone 521 of the first layer 520 and the wiring line 583 disposed on the second layer 530 may be electrically connected to each other, in an embodiment, for example, a via 582 may be formed in a portion in which the second layer 530 and the first zone 521 are in contact with each other, and the wiring line 581 of the first zone 521 may be electrically connected to the wiring line 583 of the second layer 530 via this via 582.
Referring to FIG. 5B, in the second recognition member connection part 461B, the portion (e.g., the first zone 521 of the first layer 520 and the second layer 530) in which wiring lines (e.g., the wiring lines 581 and 583 in FIG. 5A) connected to the second recognition member 460B are disposed and the portion (e.g., the second zone 522 of the first layer 520) in which a wiring line (e.g., the wiring line 584 in FIG. 5A) connected to the second contact part 480B is disposed may not overlap each other in the +Z direction. In an embodiment, for example, when the second recognition member 460B is viewed in the +Z direction with reference to FIG. 5B, as illustrated in FIG. 5B, the portion in which wiring lines connected to the second recognition member 460B are disposed and wiring lines connected to the second contact 480B are disposed may be disposed in different zones (e.g., the first zone 521 and the second zone 522 of the first layer 520) in a same layer, and may be disposed in different layers (e.g., the second zone 522 in the first layer 520 and the second layer 530) in an overlapping area, such that signal interference may be reduced.
According to various embodiments, as illustrated in FIG. 5A, a bonding member 550 may be disposed between a portion of the second recognition member 460B and a portion of the second recognition member connection part 461B. The bonding member 550 may include a conductive material. The wiring line 581 disposed in the first zone 521 of the first layer 520 may be electrically connected to the second recognition member 460B via the bonding member 550.

According to various embodiments, a third contact part 610A may be disposed in the upper portion (or the upper surface) of the first recognition member 460A (e.g., in the +Z-axis direction), and a fourth contact part 610B may be disposed in the upper portion of the second recognition member 460B. Referring to FIG. 6A, the third contact part 610A is disposed between the first support part 450 and the first recognition member 460A, and the fourth contact part 610B may be disposed between the first support part 450 and the second recognition member 460B. The third contact part 610A may be disposed in the upper portion of the first recognition member 460A at a position facing the flexible connection part 451 of the first support part 450. The fourth contact part 610B may be disposed in the upper portion of the second recognition member 460B at a position facing the flexible connection part 451 of the first support part 450. The third contact part 610A and the fourth contact part 610B may include, for example, a conductive material. In an embodiment, the third contact part 610A and the fourth contact part 610B may include substantially a same material as the first contact part 480A and the second contact part 480B described above. In an embodiment, for example, at least a portion of the third contact part 610A and the fourth contact part 610B may include an adhesive material such as a conductive tape.
In an embodiment, the first support part 450 may include glass, a film, or a conductive member, and the flexible connection part 451 of the first support part 450 may include a conductive material. According to various embodiments, the flexible connection part 451 may include a conductive material, and when the electronic device is in the folded state or the intermediate state, the flexible connection part 451 may be electrically connected to the printed circuit board 510 of the electronic device. In an embodiment, for example, when the electronic device is in the folded state or the intermediate state, the flexible connection part 451 may be electrically connected to the ground of the printed circuit board 510 by the third contact part 610A and the fourth contact part 610B.
According to various embodiments, the third contact part 610A may be disposed in the upper portion of the first recognition member 460A (e.g., in the +Z-axis direction) to be electrically connected to the first recognition member connection part 461A via the wiring line 620A included in the first recognition member 460A. The fourth contact part 610B may be disposed in the upper portion of the second recognition member 460B (e.g., in the +Z-axis direction) to be electrically connected to the second recognition member connection part 461B via the wiring line 620B included in the second recognition member 460B. Since the first recognition member connection part 461A is electrically connected to the first printed circuit board 510A and the second recognition member connection part 461B is electrically connected to the second printed circuit board 510B, the third contact part 610A may be electrically connected to the first printed circuit board 510A, and the fourth contact part 610B may be electrically connected to the second printed circuit board 510B. In an embodiment, for example, when the electronic device is in the folded state or the intermediate state, the flexible connection part 451 of the first support part 450 comes into contact with the third contact part 610A and/or the fourth contact part 610B such that the first support part 450 and the printed circuit board 510 may be electrically connected to each other. In an embodiment, one of the third contact part 610A and the fourth contact part 610B may be omitted.
According to various embodiments, the height of the third contact part 610A and/or the fourth contact part 610B may be adjusted to be in contact with the flexible connection part 451 when the flexible connection part 451 is deformed. The flexible connection part 451 may be deformed when the second housing 220 of the electronic device rotates relative to the first housing 210. As illustrated in (a) of FIG. 6C, when the flexible connection part 451 is not deformed, the third contact part 610A and/or the fourth contact part 610B may be spaced apart from the flexible connection part 451, and thus the third contact part 610A and/or the fourth contact part 610B may not come into contact with the flexible connection part 451. As illustrated in (b) of FIG. 6C, when the electronic device is in the folded state or the intermediate state, when the flexible connection part 451 is deformed, the third contact part 610A and/or the fourth contact part 610B may come into contact with the flexible connection part 451. In such a state, the flexible connection part 451 may be electrically connected to the printed circuit board 510 via the third contact part 610A and/or the fourth contact part 610B. The charges accumulated in the flexible connection part 451 may be moved to the printed circuit board 510 through contact with the third contact part 610A and/or the fourth contact part 610B. Accordingly, an undesired phenomenon (e.g., flicker) due to abnormal charge accumulation in the flexible connection part 451 may be reduced.
FIG. 7A is a schematic cross-sectional view of a display module according to various embodiments disclosed herein. FIG. 7B is a schematic view illustrating an electrical connection relationship between the recognition member and the third contact part illustrated in FIG. 7A. FIG. 7A may be a schematic cross-sectional view of the electronic device taken along line P1-P1 in FIG. 2A.
The embodiment described with reference to FIGS. 7A and 7B may be similar to the embodiment described above with reference to FIG. 4B. In the following description, the same reference numerals are used for the same or similar components as those described with reference to FIG. 4B. In addition, any repetitive detailed description of the same or similar elements as those described with reference to FIG. 4B will be omitted, and differences will be described.
According to various embodiments, the first support part 450 may include a conductive member. In an embodiment, for example, a portion of the first support part 450 other than the flexible connection part 451 may include or be formed of a conductive member. In such an embodiment, the flexible connection part 451 may include a conductive member or a non-conductive member. In another embodiment, the entire first support part 450 may include or be formed of a conductive member.
According to various embodiments, a fifth contact part 710A may be disposed in the upper portion of the first recognition member 460A (e.g., in the +Z-axis direction). A sixth contact part 710B may be disposed in the upper portion of the second recognition member 460B. Referring to FIG. 7A, the fifth contact part 710A may be disposed between the first support part 450 and the first recognition member 460A. The sixth contact part 710B may be disposed between the first support part 450 and the second recognition member 460B. In an embodiment, for example, the fifth contact part 710A may be disposed adjacent to an edge of the first recognition member 460A, and the sixth contact part 710B may be disposed adjacent to an edge of the second recognition member 460B. In another embodiment, at least a portion of the fifth contact part 710A may be disposed between the first support part 450 and the first recognition member 460A not to overlap the flexible connection part 451 when viewed in the +Z-axis direction of FIG. 7A, and at least a portion of the sixth contact part 710B may be disposed between the first support part 450 and the second recognition member 460B not to overlap the flexible connection part 451 when viewed in the +Z-axis direction of FIG. 7A. In an embodiment, the fifth contact part 710A may be disposed adjacent to the edge of the first recognition member 460A at a position adjacent to the first recognition member connection part 461A electrically connected to the first recognition member 460A. The sixth contact part 710B may be disposed adjacent to the edge of the second recognition member 460B at a position adjacent to the second recognition member connection part 461B electrically connected to the second recognition member 460B. A portion of the recognition member 460 adjacent to the first recognition member connection part 461A or the second recognition member connection part 461B may be a portion having a relatively low density of wiring lines for recognizing the pen input device compared to other portions. As described above, the fifth contact part 710A may be disposed at a position adjacent to the first recognition member connection part 461A so that the fifth contact part 710A and the sixth contact part 710B may be disposed in a portion in which the density of wiring lines is low, and the sixth contact part 710B may be disposed adjacent to the second recognition member connection part 461B. The fifth contact part 710A and the sixth contact part 710B may include, for example, a conductive material. In an embodiment, the fifth contact part 710A and the sixth contact part 710B may include or be formed of substantially a same material as the above-described second contact part 480B. In an embodiment, for example, at least a portion of the fifth contact part 710A and the sixth contact part 710B may include an adhesive material such as a conductive tape. In an embodiment, one of the fifth contact part 710A and the sixth contact part 710B may be omitted.
Referring to FIG. 7B, a first bonding area 462A may be located in a portion in which the first recognition member 460A and the first recognition member connection part 461A are connected to each other, and a second area 462B may be located in a portion in which the second recognition member 460B and the second recognition member connection part 461B are connected to each other. In an embodiment, the recognition member 460 and the recognition member connection parts 461A and 461B may be bonded to each other via an anisotropic conductive film (ACF). In such an embodiment, the first bonding area 462A and the second bonding area 462B may be understood as areas in which the ACF is disposed. The fifth contact part 710A may be disposed adjacent to the first bonding area 462A, and the sixth contact part 710B may be disposed adjacent to the second bonding area 462B. In an embodiment, for example, as illustrated in FIG. 7B, the fifth contact part 710A may be disposed in a horizontal direction (e.g., in the X-axis direction in FIG. 7B) relative to the first bonding area 462A, and the sixth contact part 710B may be disposed in a horizontal direction relative to the second bonding area 462B. Here, the direction horizontal relative to the first bonding area 462A and the second bonding area 462B may be understood as a direction perpendicular to the extension direction of the first recognition member connection part 461A and the second recognition member connection part 461B (e.g., the Y-axis direction in FIG. 7B). In a direction horizontal to portions (e.g., the bonding areas 462A and 462B) adjacent to the bonding areas 462A and 462B (e.g., in the X-axis direction in FIG. 7), conductive wiring lines for recognizing the pen input device may not be present, and may thus be desired to dispose the fifth contact part 710A and 710B in such a direction.
According to various embodiments, the fifth contact part 710A may be disposed in the upper portion of the first recognition member 460A to be electrically connected to the first recognition member connection part 461A via a wiring line 720A included in the first recognition member 460A. The sixth contact part 710B may be disposed in the upper portion of the second recognition member 460B to be electrically connected to the second recognition member connection part 461B via a wiring line 720B included in the second recognition member 460B. Since the first recognition member connection part 461A is electrically connected to the first printed circuit board 510A, and the second recognition member connection part 461B is electrically connected to the second printed circuit board 510B, the fifth contact part 710A and/or the sixth contact part 710B may be electrically connected to the first printed circuit board 510A or the second printed circuit board 510B.
