Description

Technical Field

[0001] Various embodiments of this disclosure provide a slidable electronic device with a digitizer-detached structure, and a touch driving method for the slidable electronic device. Background Technology

[0002] With the development of digital technology, various types of electronic devices, such as personal digital assistants (PDAs), e-notebooks, smartphones, tablet PCs (PCs), and wearable devices, have become widely used. Electronic devices may have a limited size for portability, thus restricting the size of the display. Therefore, in recent years, various types of electronic devices have been developed that provide extended screens through multiple displays.

[0003] For example, multiple displays can be used to provide an extended screen. Or, for instance, electronic devices are designed to progressively increase the screen size within the display, enabling the provision of various services to the user through a larger screen.

[0004] Recent electronic devices may have form factors such as multi-display (e.g., dual-display) devices (e.g., foldable, rollable, or slidable devices). Foldable devices may include foldable (or bendable) displays (e.g., foldable displays) or flexible displays, and can be folded or unfolded for use. Rollable or slidable devices may include flexible displays, and the flexible display may be rolled up and accommodated in the rear surface of the slidable device or extended to the front surface for use.

[0005] Conventional electronic devices, including displays of a specified size, include a digitizer layer and a touch layer on the display. Conventional electronic devices may include a touch layer beneath the display and a digitizer layer beneath the touch layer. Sliding electronic devices with novel form factors may include a flexible display and a touch layer in the front surface of the flexible display. The touch layer is flexible and can therefore be arranged in a layer corresponding to the flexible display. However, the digitizer layer is inflexible and therefore difficult to arrange in a layer corresponding to the flexible display. Summary of the Invention

[0006] Technical issues

[0007] Various embodiments may provide a method and apparatus in which, in a method performed by a slidable electronic device, the slidable electronic device includes a first housing and a second housing formed to be movable from the first housing, a first digitizer module disposed below a flexible display included in the first housing, a second digitizer module disposed below the first digitizer with the second housing housed inside the first housing, and filters for each region of the flexible display exposed on the front surface of the slidable electronic device are configured differently based on the movement of the second housing relative to the first housing.

[0008] Solution to the problem

[0009] An electronic device according to various embodiments of the present disclosure may include: a first housing; a second housing formed to be movable from the first housing and housed inside the first housing or exposed outside the first housing; a flexible display including a first region and a second region, wherein the second region extends from the first region and is housed on a rear surface of the second housing, or is exposed outside the first housing via a front surface of the second housing as the second housing moves; a first digitizer module located in the first housing and below the flexible display; a second digitizer module located in the second housing and below the first digitizer module when the second housing is housed inside the first housing; a memory; and a processor operatively connected to the flexible display, the first digitizer module, the second digitizer module, or the memory, wherein the processor senses movement of the second housing relative to the first housing and configures different touch filters for each region of the flexible display based on the movement of the second housing.

[0010] Operating methods of an electronic device according to various embodiments of the present disclosure may include: detecting movement of a second housing of the electronic device, wherein the second housing is formed to be movable from a first housing and may be housed inside the first housing or exposed to the outside of the first housing; and configuring different filters for each region of a flexible display of the electronic device based on the movement of the second housing, wherein the electronic device may include a first digitizer module disposed in the first housing and disposed below the flexible display; and a second digitizer module disposed in the second housing and disposed below the first digitizer module while the second housing is housed inside the first housing, and the flexible display may include a first region; and a second region extending from the first region to be housed in the rear surface of the second housing, or exposed to the outside of the first housing via the front surface of the second housing according to the movement of the second housing.

[0011] Advantages of the invention

[0012] According to various embodiments, in an electronic device including a first housing and a second housing formed to be movable from the first housing, taking into account the inflexible nature of the digitizer, the first digitizer module may be disposed below a flexible display included in the first housing, and the second digitizer module may be disposed below the first digitizer module while the second housing is housed inside the first housing.

[0013] According to various embodiments, based on the fact that the distance (or length) between the first digitizer module and the flexible display and the distance between the second digitizer module and the flexible display are different from each other, different touch filters can be applied to the first area of ​​the flexible display where the first digitizer module is provided and the second area of ​​the flexible display where the second digitizer module is provided, thereby preventing touch misidentification.

[0014] According to various embodiments, when the portion of the second region of the flexible display where the second digitizer is located is not exposed to the outside through the front surface of the electronic device, based on the movement of the second housing from the first housing, a touch filter different from the touch filter applied to another portion of the second region can be applied to the portion of the second region not exposed to the outside, thereby minimizing external noise interference in the case of touch sensing.

[0015] According to various embodiments, the drive of the first digitizer module or the second digitizer module can be turned on or off based on the movement of the second housing from the first housing, thereby minimizing touch noise interference caused by the digitizer.

Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

According to an embodiment, all or some operations to be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service.

[0057] Reference Figure 2a Electronic devices according to various embodiments (e.g., Figure 1 The electronic device 101 may include a first housing 210 and a second housing 230, wherein, in the off state of the electronic device, the second housing 230 may be housed within the first housing (210) (e.g., pocket-type). The first housing 210 is the main housing of the electronic device 101 and may house various electrical and electronic components (such as a main circuit board or battery). The first housing 210 may be fixed, and the second housing 230 may be configured to reciprocate a predetermined distance from the first housing 210 in a specified direction (e.g., the -x-axis direction D). The second housing 230 may slide from the first housing 210. A sliding structure may be provided between the first housing 210 and the second housing 230 for sliding of the second housing 230. The sliding structure (or a rollable hinge structure) may include, for example, a guide rail and a slider or roller guided to the guide rail for movement. In addition, the sliding structure may be implemented in various other ways.

[0058] Flexible display of electronic device 101 (e.g., Figure 1The display module 160 may be included in the first housing 210 and the second housing 230. In the off state of the electronic device 101, a first region A1 of the display module 160 may be exposed through the front surface of the first housing 210, and a second region A2 of the display module 160 may be accommodated in the rear surface of the second housing 230. The first region A1 may be fixed to the first housing 210, and the second region A2 may be accommodated in the rear surface of the second housing 230 or moved to the front surface of the second housing 230. For example, in the off state of the electronic device 101, the first region A1 may face a first direction (e.g., the front surface), and the second region A2 may be accommodated in the rear surface of the second housing 230 and face a second direction (e.g., the rear surface). When the second region A2 is accommodated in the rear surface of the second housing 230, the second region A2 may not be visually exposed. Optionally, if the rear surfaces of the first housing 210 and the second housing 230 are formed by a transparent cover, the second region A2 can be visually exposed through the rear surfaces of the first housing 210 and the second housing 230 even if the second region A2 is contained in the rear surface of the second housing 230.

[0059] For example, the second region A2 may be a flexible portion that changes according to the state of the electronic device 101, and may be referred to by other terms (such as a flexible region or a flexible segment). Depending on the movement (e.g., sliding movement) of the second housing 230 relative to the first housing 210, the second region A2 may be accommodated (e.g., slide-in operation) in the rear surface of the second housing 230, or moved (e.g., slide-out operation) to the front surface of the second housing 230. The second region A2 may include a region accommodated in the side region of the electronic device 101 or in the rear surface of the second housing 230 in the off state of the electronic device 101. The side region may correspond to a first side surface 205 extending from the first region A1 of the display module 160 to the second region A2. A second side surface 207 opposite to the first side surface 205 may include a plate 211 of the first housing 210, and a portion of the display module 160 (e.g., the first region A1) may be mounted on one surface of the plate 211. The first side surface 205 and the second side surface 207 may refer to side surfaces corresponding to the long length of two parallel side surfaces of the electronic device 101.

[0060] Key input device 270 may be included in a third side surface (e.g., the upper side surface of electronic device 101) corresponding to the shorter length of the two parallel side surfaces of electronic device 101. A microphone, speaker, etc., may be included in a fourth side surface (e.g., the lower side surface of electronic device 101) or in the second side surface 207, corresponding to the shorter length of the two parallel side surfaces of electronic device 101. According to an embodiment, key input device 270 may be included in the second side surface 207 or the fourth side surface of housing 210. Depending on appearance or usage, electronic device 101 may be designed to omit the described key input device 270 or include one or more key input devices. In an embodiment, electronic device 101 may include key input devices not described above, such as a home key button or a touchpad disposed around the home key button. According to another embodiment, at least a portion of key input device 270 may be disposed in an area of ​​the first housing 210.

[0061] First camera module 261 (e.g., Figure 1 The camera module 261 (in the display module 160) may be included in the first region A1 or the first housing 210 of the display module 160. For example, the first camera module 261 may be aligned with an opening (e.g., a through-hole or notch) formed in the first region A1 and located inside the electronic device 101. External light can penetrate the opening and the portion of the transparent cover that overlaps with the opening to be input to the first camera module 261. The position of the first camera module 261 may be fixed. As another example, the camera module 261 may be disposed within the internal space of the electronic device 101 to perform its function without being visually exposed through the display module 160. For example, in this case, an opening in the region of the display module 160 facing the sensor module may be unnecessary.

[0062] The first housing 210 and the second housing 230 may form a portion of a second region A2 on the rear surface of the electronic device 101 using a transparent cover. The transparent cover may be used to protect the display module 160 from external influences and may be implemented using, for example, a flexible component (such as a plastic film (e.g., polyimide film) or ultra-thin glass (UTG)). The first housing 210 may include a plurality of camera modules 262, 263, and 264 (e.g., ...) on the rear surface of the electronic device 101. Figure 1 (Camera module 180 in the middle).

[0063] The first camera module 261 or the plurality of camera modules 262, 263, and 264 may have different characteristics (e.g., field of view) and include, for example, dual or triple cameras. In some embodiments, the plurality of camera modules 262, 263, and 264 may include lenses with different field of view, and the electronic device 101 may control to change the camera modules executed in the electronic device 101 based on user selection. For example, the first camera module 261 or the plurality of camera modules 262, 263, and 264 may include at least one of a wide-angle camera, a telephoto camera, a color camera, a monochrome camera, or an infrared (IR) camera (e.g., a time-of-flight (TOF) camera and a structured light camera). The IR camera may be used as, for example, a sensor module (not shown) (e.g., Figure 1 The sensor module 176 in the system. The position of the first camera module 261 or multiple camera modules 262, 263 and 264 can be changed according to the implementation of the electronic device 101.

[0064] Figure 2b A front view 209 and a rear view 208 of an electronic device in an open state, according to various embodiments, are shown.

[0065] Figure 2b The diagram illustrates a state in which the second housing 230 of the electronic device 101 is moved from the first housing 210 (e.g., an open state), which corresponds to an increase in the size of the display module 160 exposed on the front surface of the electronic device 101. In the open state, the display module 160 exposed on the front surface of the electronic device 101 corresponds to the first region A1 and the second region A2. In the open state, the first region A1 and the second region A2 may face a first direction (e.g., the front surface). In the open state, the second region A2 may be exposed via the front surface of the second housing 230 or via the first side surface 205 of the electronic device 101 and the front surface of the second housing 230.

[0066] The open state may correspond to the state in which the second housing 230 is moved to its maximum extent from the first housing 210, for example, the state in which the second housing is moved to its maximum extent in a first direction (e.g., the -x-axis direction). The open state may mean the fully open state. An intermediate state may indicate the closed state (e.g., see...). Figure 2a ) and open state (e.g., Figure 2bThe intermediate state can indicate a state in which the second housing 230 can be further moved from the first housing 210. For example, in the intermediate state, a portion of the second region A2 exposed through the front surface of the electronic device 101 may be smaller than the portion of the second region A2 exposed through the front surface of the electronic device 101 in the open state. Another portion A2-2' of the second region A2 exposed through the rear surface of the electronic device 101 in the intermediate state may be larger than another portion A2-2 of the second region A2 exposed through the front surface of the electronic device 101 in the open state. The intermediate state may include multiple stages (e.g., stages not described above). In the electronic device 101, the size of the display module 160 exposed through the front or rear surface of the electronic device 101 can be changed, as with the distance the second housing 230 is moved from the first housing 210.

[0067] Although the figures depict another portion A2-2 of the second region A2 being housed within the side or rear surface of the second housing 230 in the open state, in the open state of the electronic device 101, both the first region A1 and the second region A2 of the display module 160 can be exposed through the front surface of the electronic device 101, and the display module 160 may not be exposed through the rear surface of the electronic device 101. This is merely an implementation issue and does not limit this disclosure.

[0068] According to various embodiments, in the open state of the electronic device 101, a portion of the second region A2 can be exposed through the front surface of the second housing 230, and another portion of the second region A2 can be accommodated in the side or rear surface of the second housing 230. For example, the portion of the second region A2 exposed through the front surface of the electronic device 101 (e.g., A2'+A2-1) may include the side region A2' corresponding to the first side surface 205 and the portion A2-1 of the second region A2. In the open state of the electronic device 101, another portion A2-2 of the second region A2 can be accommodated in the side or rear surface of the second housing 230. Optionally, in an intermediate state of the electronic device 101, a portion of the second region A2 (e.g., A2'+A2-1) can be exposed through the front surface of the electronic device 101, and another portion A2-2 of the second region A2 can be accommodated in the rear surface of the second housing 230.

[0069] According to various embodiments, electronic device 101 can utilize a sensor module (e.g., Figure 1The sensor module 176 in the sensor module 176 detects the state of the electronic device 101. For example, the electronic device 101 can detect whether it is in an off state, an intermediate state, or an on state based on the sensing signal detected by the sensor module 176. In the intermediate state, the electronic device 101 can detect how much the second housing 230 has moved from the first housing 210 based on the sensing signal. Alternatively, the electronic device 101 can detect how much the second housing 230 has moved from the first housing 210 based on a sliding structure.

[0070] According to various embodiments, when the display module 160 is moved a configured distance by external force, the electronic device 101 can move relative to the first housing 210 (e.g., from a closed state to an open state, or from an open state to a closed state) to the second housing 230 without further external force (e.g., semi-automatic sliding operation) due to the elastic structure included in the sliding structure. According to embodiments, when a signal is generated by the key input device 270 included in the electronic device 101, the electronic device 101 can move relative to the first housing 210 (e.g., from a closed state to an open state (or an intermediate state), or from an open state (or an intermediate state) to a closed state) to the second housing 230 via a drive device (such as a motor) connected to the display module 160. For example, when a signal is generated by a hardware button or software button provided via the screen, the electronic device 101 can move from a closed state to an open state (or an intermediate state) or from an open state (or an intermediate state) to a closed state.

[0071] although Figure 2a and Figure 2b An example is shown where the size of the display of electronic device 101 is increased in the -x-axis direction (e.g., the left direction), but the size of the display of electronic device 101 can also be increased in the +x-axis direction (e.g., the right direction), the +y-axis direction (e.g., the upward direction), or the -y-axis direction (e.g., the downward direction). That is, the size of the display of electronic device 101 can be increased in the horizontal direction, expanded in the left or right direction, or expanded in both directions. Similarly, the size of the display of electronic device 101 can be increased in the vertical direction, expanded in the upward or downward direction, or expanded in both directions. An example of increasing the size of the display in the left direction is described below, but this is merely an implementation example and does not limit this disclosure.

[0072] Figure 3 This is a view showing an example of the setup of a digitizer module in an electronic device according to various embodiments.

[0073] Reference Figure 3Sliding electronic devices according to various embodiments (e.g., Figure 1 Electronic device 101) may include, in the off state 310, a flexible display (e.g., Figure 1 The first digitizer module 301 and the second digitizer module 303 are located below the display module 160. The closed state 310 of the figure shows a cross-sectional view of a side surface (e.g., the upper or lower side surface of the electronic device 101) corresponding to the short length of the two parallel side surfaces of the electronic device 101.

[0074] According to an embodiment, electronic device 101 can detect a magnetic field signal, including a resonant frequency, generated from a stylus using an electromagnetic resonance (EMR) method via a first digitizer module 301 and a second digitizer module 303. For example, when alternating current is applied through multiple coils of the first digitizer module 301 and the second digitizer module 303, current can flow through the coils inside the stylus adjacent to the first digitizer module 301 and the second digitizer module 303 according to the law of electromagnetic induction. A signal including the resonant frequency can be formed by a resonant circuit inside the stylus, and the first digitizer module 301 and the second digitizer module 303 can detect the resonant frequency. The resonant circuit may include at least one coil, an inductor, and / or electronic components such as a capacitor. According to an embodiment, the resonant circuit can be used to change the strength or frequency of the electromagnetic field according to the user's operating state. For example, the resonant circuit can provide various frequencies to identify floating input, drawing input, button input, or erase input.

[0075] The closed state 310 can be connected to the second housing (e.g., Figure 2a and Figure 2b The second housing 230 is included (accommodated) within the first housing of the electronic device 101 (e.g., Figure 2a and Figure 2b The state corresponds to that in the first housing 210. In the closed state 310, the second housing 230 can be fully inserted into the first housing 210, so that the second housing 230 is not exposed to the outside. In the closed state 310, only the first area of ​​module 160 is displayed (e.g., Figure 2a and Figure 2b The first region A1 of the display module 160 can be exposed externally (e.g., via a first direction or the front surface of the electronic device 101), and the second region of the display module 160 (e.g., Figure 2a and Figure 2bThe second region A2 may not be exposed to the outside. In the closed state 310, the second region A2 may face a second direction opposite to the first direction (e.g., the rear surface of the electronic device 101). The first housing 210 may correspond to the main housing of the electronic device 101 and may include a processor (e.g., Figure 1 The processor 120 in the memory includes memory (e.g., Figure 1 The main circuit board 315 of the memory 130 in the memory, or the battery (e.g., Figure 1 Battery 189 in the middle.

[0076] The first digitizer module 301 may be included in the first housing 210, and the second digitizer module 303 may be included in the second housing 230. Figure 3 In this design, the first housing 210 may be fixed, and the second housing 230 may have a form in which the area corresponding to the second housing 230 is exposed when extended. The second digitizer module 303 may have an internal support fixed to the second housing 230 and be exposed together when the second housing 230 moves. For example, the digitizer has an inflexible characteristic, so the digitizer module (or layer) may be divided into two modules, such that one module is included in the first housing 210 and the other module is included in the second housing 230. The digitizer module may be an input device for reading coordinates (which are analog data) and inputting drawings or graphics designed in digital form. For example, the first digitizer module 301 or the second digitizer module 303 may identify coordinates (e.g., X and Y coordinates) corresponding to the contact position of the stylus on the display module 160. In the following description, the display module 160 is described as facing upwards in the closed state 310 (e.g., in the direction opposite to the direction of gravity). However, the description is not intended to limit this disclosure.

[0077] In the closed state 310, the first digitizer module 301 may be disposed below at least a portion of the display module 160 (or on the rear surface). In the closed state 310, a sliding structure (or component) 305 may be included below at least another portion of the display module 160. The sliding structure 305 (or a rollable hinge structure) may correspond to a structure for moving the second housing 230 relative to the first housing 210. In the closed state 310, the second digitizer module 303 may be disposed below the first digitizer module 301. That is, in the closed state 310, the first digitizer module 301 may be disposed below (or on the rear surface) the display module 160, and the second digitizer module 303 may be disposed below the first digitizer module 301. This is merely an implementation issue, and the description in the drawings does not limit this disclosure. According to an embodiment, a metal layer may be disposed on the first digitizer module 301 or the second digitizer module 303, and a pattern may be formed on the metal layer disposed on the second digitizer module 303 to serve as a sliding structure (grid).

[0078] In the off state 310, the first distance d1 (or length) between the display module 160 and the first digitizer module 301 (e.g., Figure 4c The first distance d1 between the display module 160 and the second digitizer module 303 may be different from the second distance d2 between them. Figure 4c The first distance d1 may be shorter than the second distance d2 (e.g., d2 > d1) because the first digitizer module 301 is disposed in the first housing 210, the second digitizer module 303 is disposed in the second housing 230, and the second digitizer module 303 is disposed below the first digitizer module 301. For example, the distance between the second digitizer module 303 and the display module 160 (e.g., the second distance d2) may be longer than the distance between the first digitizer module 301 and the display module 160. The distance between the first digitizer module 301 and the display module 160 (e.g., the first distance d1) may be shorter than the distance between the second digitizer module 303 and the display module 160. The first distance d1 between the display module 160 and the first digitizer module 301 may indicate the distance from the touch input window of the display module 160 to the rear surface of the first digitizer module 301. The second distance d2 between the display module 160 and the second digitizer module 303 can indicate the distance from the touch input window of the display module 160 to the rear surface of the second digitizer module 303.

[0079] According to various embodiments, in the open state 350, the electronic device 101 may include a first digitizer module 301 below a first region A1 of the display module 160 corresponding to the first housing 210 and a second digitizer module 303 below a second region A2 of the display module 160 corresponding to the second housing 230. The open state 350 in the figures may show a cross-sectional view of a side surface (e.g., the upper or lower side surface of the electronic device 101) corresponding to the short length of two parallel side surfaces of the electronic device 101. The open state 350 may indicate a state in which the second housing 230 is exposed to the outside of the first housing 210. In the open state 350, the second housing 230 may be moved to the outside of the first housing 210 to the maximum extent possible, thereby exposing the second housing 230 to the outside. The open state 350 may correspond to a state in which the first region A1 and the second region A2 of the display module 160 are exposed to the outside (e.g., in a first direction or on the front surface of the electronic device 101). In the open state 350, the second region A2 may face the same first direction as the first region A1 (e.g., the front surface of the electronic device 101).

[0080] In the open state 350, the first digitizer module 301 may be disposed below the first region A1 of the display module 160 corresponding to the first housing 210, and the second digitizer module 303 may be disposed below the second region A2 of the display module 160 corresponding to the second housing 230. According to various embodiments, a sliding structure (or component) 305 may be included between the second digitizer module 303 and the second region A2 of the display module 160.

[0081] In the open state 350, the first distance d1 (or length) between the display module 160 and the first digitizer module 301 may differ from the second distance d2 between the display module 160 and the second digitizer module 303. Since the first digitizer module 301 is disposed in the first housing 210 and the second digitizer module 303 is disposed in the second housing 230, which is formed to be housed inside the first housing 210, and the second digitizer module 303 is disposed below the first digitizer module 301, the first distance d1 may be shorter than the second distance d2. The distance between the second digitizer module 303 and the display module 160 (e.g., the second distance d2) may be longer than the distance between the first digitizer module 301 and the display module 160. The distance between the first digitizer module 301 and the display module 160 (e.g., the first distance d1) may be shorter than the distance between the second digitizer module 303 and the display module 160. A first distance d1 between the display module 160 and the first digitizer module 301 indicates the distance from the touch input window of the display module 160 to the rear surface of the first digitizer module 301. A second distance d2 between the display module 160 and the second digitizer module 303 indicates the distance from the touch input window of the display module 160 to the rear surface of the second digitizer module 303. According to an embodiment, there is a height difference between the first digitizer module 301 and the second digitizer module 303 (e.g., the difference between the first distance d1 and the second distance d2), and a stepped compensation layer can be provided between the second digitizer module 303 and the sliding structure (grid).

[0082] Figures 4a to 4c This is a view illustrating examples of mobile application touch filters based on the housing of an electronic device according to various embodiments.

[0083] Figure 4a This is a view illustrating examples of applying a touch filter in the off state of an electronic device according to various embodiments.

[0084] Reference Figure 4a Sliding electronic devices according to various embodiments (e.g., Figure 1 Electronic device 101) can be used for flexible displays (e.g., when they are in the off state 410) Figure 1 The first region 411 of the display module 160 in the middle (e.g., Figure 2a and Figure 2b The first touch filter is applied to the first area A1 in the middle. The closed state 410 can be connected to the second housing (e.g., Figure 2a and Figure 2b The second housing 230 is included (accommodated) within the first housing of the electronic device 101 (e.g., Figure 2a and Figure 2bThe state corresponds to the state of the first housing 210 in the closed state. In the closed state 410, the second housing 230 can be fully inserted into the first housing 210, so that the second housing 230 is not exposed to the outside. In the closed state 410, only the first area A1 of the display module 160 can be exposed to the outside (e.g., the first direction or the front surface of the electronic device 101), and the second area of ​​the display module 160 (e.g., Figure 2a and Figure 2b The second region A2 in the middle may not be exposed to the outside. Figure 4a The first region 411 in the middle can be compared with Figure 2a and Figure 2b The first region A1 in the text corresponds to this. Optionally, Figure 4a The first region 411 in the middle can be compared with Figure 2a and Figure 2b The first region A1 is the same.

[0085] According to various embodiments, the display module 160 may include a touch electrode layer (or touch layer) on the display panel and a first digitizer module below the display panel (e.g., Figure 3 a and Figure 3 The first digitizer module 301 in b) or the second digitizer module (e.g., Figure 3 a and Figure 3 The second digitizer module 303 in b). Optionally, the display module 160 may include an add-on method for attaching a separate touchscreen panel (TSP) to the display, an on-cell method for patterning on the lower part of the polarization layer or the upper part of the encapsulation layer, or an in-cell method for setting on a thin-film transistor (TFT) substrate inside the display, and may include a first digitizer module 301 or a second digitizer module 303 below the display panel. The first digitizer module 301 may be disposed in the first housing 210 corresponding to the first region A1 of the display module 160. The second digitizer module 303 may be disposed in the second housing 230 corresponding to the second region A2 of the display module 160.

[0086] The touch layer (or touch sensor) may be affected by external noise, display panel noise, or noise from the digitizer module. When the touch layer is affected by noise, mis-touch recognition may occur. Furthermore, in cases such as electronic device 101 including two digitizer modules (e.g., first digitizer module 301 and second digitizer module 303), the touch layer may be affected differently depending on the arrangement of the two digitizer modules. Since the arrangement of the two digitizer modules in this disclosure changes according to the movement of the second housing 230 relative to the first housing 210, a method for reducing touch noise based on the movement of the second housing 230 can be provided.

[0087] In the off state 410, where the first digitizer module 301 is positioned below the display module 160 and the second digitizer module 303 is positioned below the first digitizer module 301, the electronic device 101 can apply a first touch filter to a first area A1 of the display module 160. The first touch filter can be a filter applied to an electronic device comprising one digitizer module and one touch layer, rather than a structure comprising two digitizer modules. The first filter can be pre-configured by a first distance d1 between the display module 160 and the first digitizer module 301.

[0088] The first touch filter equalizes the touch baseline corresponding to the first region 411 to remove touch noise. The touch baseline may refer to the capacitor value associated with touch detection. Considering that the touch layer can detect touch input based on changes in capacitor value, the analog front-end (AFE) value may be distorted if the baseline is not equalized, and touch misidentification may occur due to noise. Since only the first region 411 is exposed to the outside when the electronic device 101 is in the off state 410, the first touch filter can be applied to the first region 411 based on the first distance d1 between the display module 160 and the first digitizer module 301. When the first touch filter is applied to the first region 411, the touch baseline of the first region 411 can be updated based on the first touch filter.

[0089] According to various embodiments, in the off state 410, the electronic device 101 may drive (e.g., turn on or enable) the first digitizer module 301 and may not drive (e.g., turn off or disable) the second digitizer module 303. Since only the first area 411 is exposed to the outside in the off state 410 of the electronic device 101, the first digitizer module 301 can be used, and the second digitizer module 303 may not be used. The second digitizer module 303 is used when the second area A2 is exposed, and therefore may not be used when only the first area 411 is exposed to the outside. The electronic device 101 may not drive the unused second digitizer module 303 to minimize touch noise caused by the second digitizer module 303. Alternatively, in order to minimize noise interference caused by the first digitizer module 301 and the second digitizer module 303 and reduce power consumption, the second digitizer module 303 may not be driven in the off state 410.

[0090] Figure 4b This is a view illustrating examples of applying a touch filter in an intermediate state of an electronic device according to various embodiments.

[0091] Reference Figure 4bIn intermediate state 430, electronic device 101 can apply a first touch filter to a first region 431 of display module 160, a second touch filter to a second region 433 of display module 160, and a third touch filter to a third region 435 of display module 160. Intermediate state 430 can indicate a state in which a portion of the second housing 230 (e.g., the second region 433) is exposed to the outside of the first housing 210. In intermediate state 430, portions of the first region A1 and the second region A2 of display module 160 (e.g., the second region 433) can be exposed externally (e.g., in a first direction or on the front surface of electronic device 101), and another portion 440 of the second region A2 can face a direction opposite to that of the first region A1 (e.g., in a second direction or on the rear surface of electronic device 101).

[0092] The first region 431 may be a region exposed through the first housing 210 and not overlapping with the second housing 230. The first region 431 may be smaller than Figure 2a and Figure 2b The first region A1 in the diagram. For example... Figure 2a and Figure 2b The first region A1 in the text can be referred to through combination Figure 4b The areas obtained by the first region 431 and the third region 435. The second region 433 may be the region where the second housing 230 is exposed to the outside of the first housing 210 and does not overlap with the first housing 210. The second region 433 may be... Figure 2a and Figure 2b The second region A2 corresponds to a portion (e.g., A2-1) and can be less than Figure 2a and Figure 2b The third region 435 can be the region where the first housing 210 and the second housing 230 overlap when the second housing 230 is housed inside the first housing 210. The third region 435 can be... Figure 2a and Figure 2b Part of the first region A1 or Figure 2a and Figure 2b The other part of the second region A2 in the text corresponds to this.

[0093] For example, the second region 433 may be a portion of the second region A2 of the display module 160 (e.g., A2-1), which the user can access when the second housing 230 moves. The third region 435 may be a portion of the user-accessible first region A1 of the display module 160 and another portion of the user-inaccessible second region A2 of the display module 160. Optionally, the third region 435 may refer to another portion of the second region A2 that is covered by the first region A1 and is not visible to the user.

[0094] The first touch filter f1 can be configured based on a first distance d1 between the display module 160 and the first digitizer module 301. The second touch filter can be configured based on either the first distance d1 between the display module 160 and the first digitizer module 301 or a second distance d2 between the display module 160 and the second digitizer module 303. Since the first digitizer module 301 is disposed in the first housing 210, and the second digitizer module 303 is disposed in the second housing 230, and the second digitizer module 303 is disposed below the first digitizer module 301, the first distance d1 can be shorter than the second distance d2.

[0095] Since the user has access to the display module 160 and the second digitizer module 303 corresponding to the second area 433 is driven, the second area 433 can be affected by the second digitizer module 303. For example, the second touch filter f2 can be configured based on a value obtained by subtracting the first distance d1 from the second distance d2 and then dividing the difference by the second distance d2. The second touch filter f2 can be smaller than the first touch filter f1.

[0096] Since the third region 435 corresponds to a portion of the first region A1 and a portion of the second region A2, the first digitizer module 301 corresponding to the third region 435 can be driven, and the second digitizer module 303 corresponding to the third region 435 can be driven or not driven. The third region 435 can be affected by the first digitizer module 301 and the second digitizer module 303. The third touch filter can be configured based on the first touch filter and the second touch filter. For example, the third touch filter f3 can be equal to or greater than the sum of the first touch filter f1 and the second touch filter f2. For example, in the intermediate state 430, the electronic device 101 can drive the entire second digitizer module 303 or can not drive a portion of the second digitizer module 303 (e.g., the third region 435). When driving the second digitizer module 303 corresponding to the third region 435, the electronic device 101 can apply the third touch filter f3 to the third region 435. Optionally, if the second digitizer module 303 corresponding to the third region 435 is not driven, the electronic device 101 may apply either the first touch filter f1 or the second touch filter f2 to the third region 435. Optionally, regardless of whether the second digitizer module 303 corresponding to the third region 435 is driven, the electronic device 101 may apply the third touch filter f3 to the third region 435. This is merely an implementation issue and does not limit this disclosure.

[0097] According to various embodiments, the distance can be inversely proportional to the touch noise. For example, since the touch noise increases in the order of third region 435, first region 431, and second region 433, the touch filter value can increase in the order of third region 435, first region 431, and second region 433. For example, since the touch noise is greatest in the third region 435 where the first digitizer module 301 and the second digitizer module 303 overlap, the value of the third touch filter f3 applied to the third region 435 can be the greatest.

[0098] According to various embodiments, electronic device 101 may update the touch baseline based on movement of the second housing 230 relative to the first housing 210. Movement of the second housing 230 relative to the first housing 210 may refer to a state transition (change) of electronic device 101 from an off state to an intermediate state or an on state, or a state transition of electronic device 101 from an on state to an intermediate state or an off state. Electronic device 101 may update the touch baseline based on the state transition (change) of electronic device 101.

[0099] For example, when a first touch filter is applied to a first region 431, the touch baseline of the first region 431 can be updated based on the first touch filter. When a second touch filter is applied to a second region 433, the touch baseline of the second region 433 can be updated based on the second touch filter. When a third touch filter is applied to a third region 435, the touch baseline of the third region 435 can be updated based on the third touch filter. Optionally, when either a first touch filter or a second touch filter is applied to the third region 435, the touch baseline of the third region 435 can be updated based on either the first touch filter or the second touch filter.

[0100] According to various embodiments, in intermediate state 430, electronic device 101 may drive (e.g., turn on or enable) the first digitizer module 301 and drive the entire area of ​​the second digitizer module 303, or may not drive (e.g., turn off or disable) a portion of the second digitizer module 303. In intermediate state 430, electronic device 101 may drive the first digitizer module 301 corresponding to the first area 431 and the third area 435, and drive the second digitizer module 303 corresponding to the second area 433 or the third area 435. Optionally, in the second digitizer module 303, a portion of the second digitizer module 303 corresponding to the second area 433 may be driven, and a portion of the second digitizer module 303 corresponding to the third area 435 may not be driven.

[0101] Electronic device 101 can divide the first digitizer module 301 or the second digitizer module 303 into multiple regions, and control the portion of the region to be sensed and the portion of the region to be unsensed. For example, in order to minimize noise interference and reduce power consumption of the first digitizer module 301 and the second digitizer module 303, in intermediate state 430, electronic device 101 can control the portion of the first digitizer module 301 corresponding to the first region 431 and the third region 435, and the portion of the second digitizer module 303 corresponding to the second region 433 to be sensed, and control the portion of the second digitizer module 303 corresponding to the third region 435 to be unsensed.

[0102] According to various embodiments, since driving the first digitizer module 301 or the second digitizer module 303 may cause touch noise, the electronic device 101 can apply different filters to corresponding areas based on driving the first digitizer module 301 or the second digitizer module 303. For example, the first digitizer module 301 can be driven in the first area 431, the second digitizer module 303 can be driven in the second area 433, the first digitizer module 301 can be driven in the third area 435 and the second digitizer module 303 may not be driven, and the second digitizer module 303 may be positioned below the first digitizer module 301. Therefore, the electronic device 101 can apply a first touch filter f1 to the first area 431, a second touch filter f2 to the second area 433, and a third touch filter f3 to the third area 435. The value configured for the first touch filter f1 may be less than the value of the second touch filter f2 and greater than the value of the third touch filter f3.

[0103] According to various embodiments, in the intermediate state 430 of the electronic device 101, the electronic device 101 can determine the touch filter to be applied to the third region 435 based on the driving method of the second digitizer module 303. When the entire region of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101, the electronic device 101 can apply the third touch filter to the third region 435. Optionally, when only a portion of the second digitizer module 303 (e.g., the second region 433) is driven in the intermediate state 430 of the electronic device 101, the electronic device 101 can apply either the first or the second touch filter to the third region 435. Optionally, regardless of the driving state of the second digitizer module 303 in the intermediate state 430 of the electronic device 101, the electronic device 101 can apply the third touch filter to the third region 435.

[0104] According to various embodiments, the electronic device 101 may apply the value between the first touch filter f1 and the third touch filter f3 (an intermediate filter value between the first touch filter f1 and the third touch filter f3 (e.g., the second touch filter f2)) to a configuration region (e.g., a boundary region) between the first region 431 and the third region 435, and apply the filter value between the second touch filter f2 and the third touch filter f3 to a configuration region between the second region 433 and the third region 435. Optionally, the electronic device 101 may apply the first touch filter f1 (e.g., the larger value between the first touch filter f1 and the third touch filter f3) to a configuration region (e.g., a boundary region) between the first region 431 and the second region 435, and apply the second touch filter f2 (e.g., the larger value between the second touch filter f2 and the third touch filter f3) to a configuration region between the second region 433 and the third region 435.

[0105] Figure 4c This is a view illustrating examples of applying a touch filter in the open state of an electronic device according to various embodiments.

[0106] Reference Figure 4c In the open state 450, the electronic device 101 can apply a first touch filter to the first area 451 of the display module 160 and apply a second touch filter to the second area 453 of the display module 160. The open state 450 indicates that the second housing 230 is exposed to the outside of the first housing 210. In the open state 450, the second housing 230 can be moved to the outside of the first housing 210 to the maximum extent possible, thus exposing the second housing 230 to the outside. The open state 450 corresponds to the state in which the first area A1 and the second area A2 of the display module 160 are exposed to the outside (e.g., a first direction or the front surface of the electronic device 101). In the open state 450, the second area A2 can face the same first direction as the first area A1 (e.g., the front surface of the electronic device 101).

[0107] In the open state 450, the first region 451 may be a region corresponding to the first housing 210, exposed to the outside through the first housing 210 (e.g., in a first orientation or on the front surface of the electronic device 101), and not overlapping with the second housing 230. The first region 451 may be... Figure 2a and Figure 2b The second region 453 corresponds to and may be identical to the first region A1. The second region 453 may correspond to the second housing 230, be exposed to the outside through the second housing 230 (e.g., in the first direction or on the front surface of the electronic device 101), and not overlap with the first housing 210. The second region 453 may correspond to... Figure 2a and Figure 2bIt corresponds to the second region A2 in the text, and can be the same as the second region A2.

[0108] The first touch filter f1 can be configured based on a first distance d1 between the display module 160 and the first digitizer module 301. The second touch filter can be configured based on either the first distance d1 between the display module 160 and the first digitizer module 301 or a second distance d2 between the display module 160 and the second digitizer module 303. The first distance d1 can be shorter than the second distance d2 (e.g., d2 > d1). Since the user can access the display module 160 and the second digitizer module 303 corresponding to the second area 453 is activated, the second area 453 can be affected by the second digitizer module 303. For example, the second touch filter f2 can be configured by a value obtained by subtracting the first distance d1 from the second distance d2 and then dividing the difference by the second distance d2. The second touch filter f2 can be smaller than the first touch filter f1.

[0109] According to various embodiments, the electronic device 101 may update the touch baseline based on the movement of the second housing 230 relative to the first housing 210. The movement of the second housing 230 relative to the first housing 210 may refer to a state transition (change) of the electronic device 101 from an off state to an on state or from an on state to an off state. The electronic device 101 may update the touch baseline based on the state transition (change) of the electronic device 101. For example, when a first touch filter is applied to a first region 451, the touch baseline of the first region 451 may be updated based on the first touch filter. When a second touch filter is applied to a second region 453, the touch baseline of the second region 453 may be updated based on the second touch filter.

[0110] According to various embodiments, in the open state 450, the electronic device 101 can drive (e.g., turn on or enable) the first digitizer module 301 and can drive (e.g., turn on or enable) the second digitizer module 303. In the open state 450, the electronic device 101 can drive the first digitizer module 301 corresponding to the first region 431 and drive the second digitizer module 303 corresponding to the second region 433. Since driving the first digitizer module 301 or the second digitizer module 303 may cause touch noise, the electronic device 101 can apply different filters to the corresponding regions based on driving the first digitizer module 301 or the second digitizer module 303. For example, the first digitizer module 301 can be driven in the first region 451, and the second digitizer module 303 can be driven in the second region 453, and the digitizer modules can be non-overlapping in the first region 451 and the second region 453. Therefore, the electronic device 101 can apply a first touch filter f1 to the first region 451 and a second touch filter f2 to the second region 453. The value assigned to the first touch filter f1 can be less than the value assigned to the second touch filter f2.

[0111] Figures 5a to 5c This is a view illustrating examples of applying a touch filter to touch noise in an electronic device according to various embodiments.

[0112] Figure 5a This is a view illustrating examples of applying a touch filter in the off state of an electronic device according to various embodiments.

[0113] Reference Figure 5a The first graph 510 can depict the sliding electronic device (e.g., according to various embodiments) according to various embodiments. Figure 1 The off state of electronic device 101 in the device (e.g., Figure 4a The initial noise condition in case 410). The closed state 410 can be connected with the second housing (e.g., Figure 2a and Figure 2b The second housing 230 is included (accommodated) within the first housing of the electronic device 101 (e.g., Figure 2a and Figure 2b The state corresponds to that in the first housing 210. In the closed state 410, the second housing 230 can be fully inserted into the first housing 210, so that the second housing 230 is not exposed to the outside. In the closed state 410, only the flexible display (e.g., Figure 1 The first area of ​​the display module 160 in the middle (e.g., Figure 2a and Figure 2b The first region A1 and Figure 4aThe first region 411 of the display module 160 can be exposed externally (e.g., in a first direction or on the front surface of the electronic device 101), and the second region of the display module 160 (e.g., Figure 2a and Figure 2b The second region A2 in the middle may not be exposed to the outside.

[0114] The y-axis of the first graph 510 indicates raw data regarding touch noise, and the x-axis corresponds to the first region A1. Referring to the first graph 510, the initial touch noise (or touch sensitivity) in the off state 410 can vary for each region of the first region A1. A first digitizer module (e.g., ) included in the first housing 210 can be driven. Figure 3 The first digitizer module 301 in the housing 230 may not drive the second digitizer module included in the second housing 230 (e.g., Figure 3 The second digitizer module 303 in the display module 160 may be affected by external noise, noise from the display panel, or noise from the digitizer module. Since the second digitizer module 303 may affect the touch noise of the first region A1 in the off state 410, the electronic device 101 may not drive the second digitizer module 303 in the off state 410. The electronic device 101 may apply a first touch filter f1 to the first region A1 in the off state 410. When the first touch filter f1 is applied to the first region A1, the touch noise of each region of the first region A1 can be equalized by uniformly correcting the touch baseline responding to the first region A1 (e.g., smoothing the slope of the original touch data or reducing it to a value of "0").

[0115] Figure 5b This is a view illustrating examples of applying a touch filter in the open state of an electronic device according to various embodiments.

[0116] Reference Figure 5b The second graph 520 can depict the open state of the electronic device 101 (e.g., Figure 4c The initial noise condition under condition 450. Open state 450 indicates that the second housing 230 is exposed to the outside of the first housing 210. In open state 450, the second housing 230 can be moved to the outside of the first housing 210 to the maximum extent possible, thus exposing the second housing 230 to the outside. Open state 450 corresponds to the state where the first region A1 and the second region A2 of the display module 160 are exposed to the outside (e.g., a first direction or the front surface of the electronic device 101). In open state 450, the second region A2 can face the same first direction as the first region A1 (e.g., the front surface of the electronic device 101).

[0117] The y-axis of the second graph 520 indicates the raw data regarding touch noise, and the x-axis corresponds to the first region A1 and the second region A2. Referring to the second graph 520, the initial touch noise may appear differently in the first region A1 and the second region A2 under the open state 450. Under the open state 450, the first digitizer module 301 included in the first housing 210 and the second digitizer module 303 included in the second housing 230 can be driven. Under the open state 450, the first digitizer module 301 and the second digitizer module 303 can affect the touch noise of the first region A1 and the second region A2. The electronic device 101 can apply a first touch filter f1 to the first region A1 and a second touch filter f2 to the second region A2 under the open state 450.

[0118] The third graph 530 depicts the touch noise after applying the first touch filter f1 to the first region A1 and the second touch filter f2 to the second region A2 in the open state 450. By applying different touch filters to the first region A1 and the second region A2, the touch noise in the first region A1 and the second region A2 can be equalized by uniformly correcting the touch baselines responding to the first region A1 and the second region A2.

[0119] Figure 5c This is a view illustrating examples of applying a touch filter in an intermediate state of an electronic device according to various embodiments.

[0120] Reference Figure 5c The fourth curve 540 can depict the intermediate state of the electronic device 101 (e.g., Figure 4b The initial noise condition in the case of intermediate state 430. Intermediate state 430 can indicate the state in which a portion of the second housing 230 is exposed to the outside of the first housing 210. In intermediate state 430, portions of the first region A1 and the second region A2 of the display module 160 (e.g., Figure 4b The second region 433) can be exposed externally (e.g., in the first direction or on the front surface of the electronic device 101), and another portion of the second region A2 (e.g., Figure 4b 440 in the middle may face a direction opposite to the first region A1 (e.g., a second direction or the rear surface of the electronic device 101).

[0121] The y-axis of the fourth curve, 540, indicates the raw data regarding touch noise, and the x-axis can be compared with... Figures 4a to 4cThe first region 431, the second region 433, and the third region 435 correspond to each other. The first region 431 may be a region exposed through the first housing 210 and not overlapping with the second housing 230. The second region 433 may be a region where the second housing 230 is exposed to the outside of the first housing 210 and does not overlap with the first housing 210. The third region 435 may be a region where the first housing 210 and the second housing 230 overlap when the second housing 230 is housed inside the first housing 210. Referring to the fourth curve 540, in the intermediate state 430, the initial touch noise may be relatively large, following the order of the third region 435, the first region 431, and the second region 433. Since touch noise is inversely proportional to distance, the touch noise can be reduced as the distance between the first digitizer module 301 or the second digitizer module 303 and the display module 160 increases.

[0122] For example, the second region 433 may correspond to the second distance d2 between the second digitizer module 303 and the display module 160, and the first region 431 may correspond to the first distance d1 between the first digitizer module 301 and the display module 160. Since the first digitizer module 301 is disposed in the first housing 210, the second digitizer module 303 is disposed in the second housing 230, and the second digitizer module 303 is disposed below the first digitizer module 301, the first distance d1 may be shorter than the second distance d2 (e.g., d2>d1). Furthermore, since the third region 435 corresponds to a portion of the first region A1 and a portion of the second region A2, the first digitizer module 301 corresponding to the third region 435 may be driven, while the second digitizer module 303 corresponding to the third region 435 may not be driven. The third region 435 may be affected by the first digitizer module 301 and the second digitizer module 303.

[0123] The fifth curve 550 depicts the touch noise after applying the first touch filter f1 to the first region 431 through the third region 435. It can be identified that touch noise exists with respect to the second region 433 when only the first touch filter f1 is applied, and the touch noise is relatively large with respect to the third region 435. Since the touch noise is different for each region of the display module 160 (e.g., the first region 431 through the third region 435) in the intermediate state 430, the electronic device 101 can apply the touch filter differently for each region of the display module 160.

[0124] The sixth curve 560 depicts the touch noise after applying a first touch filter f1 to a first region 431, a second touch filter f2 to a second region 433, and a third touch filter f3 to a third region 435. In the intermediate state 430, the electronic device 101 can apply the first touch filter f1 to the first region 431, the second touch filter f2 to the second region 433, and the third touch filter f3 to the third region 435. The second touch filter may be smaller than the first touch filter. The third touch filter may be equal to or greater than the sum of the first touch filter f1 and the second touch filter f2.

[0125] Figure 6 This is a view illustrating examples of a digitizer module and a display driver circuit, including an electronic device, according to various embodiments.

[0126] Reference Figure 6 Sliding electronic devices according to various embodiments (e.g., Figure 1 Electronic device 101 in the middle may include a processor (e.g., Figure 1 The processor 120), display driver circuit 600, touch controller 670, digitizer controller 680, display panel 690 or digitizer module 695 are included. Although Figure 6 A digitizer module 695 is shown, but the slidable electronics 101 may include two digitizer modules (e.g., Figure 3 The first digitizer module 301 and the second digitizer module 303 in the middle). The slidable electronic device 101 may include a flexible display (e.g., Figure 1 The display module 160 may include a display driver circuit 600 and a display panel 690.

[0127] Processor 120 can generate a user interface to be displayed on display panel 690 and determine the screen refresh rate based on the generated user interface. Processor 120 may include a graphics processing unit (GPU) and TSP firmware. Processor 120 can send control signals to display driver circuitry 600 via GPU regarding the screen refresh rate or pixel data (or image data) corresponding to the user interface. Processor 120 can calculate coordinate information obtained from touch controller 670 by TSP firmware.

[0128] The display driver circuit 600 (display driver integrated circuit (DDI)) may include an interface 610, a graphics memory 620, an image processing module 630, a controller 640, a gate driver 650, or a source driver 660. The interface 610 may receive image data from the processor 120. The image data may include still image data or moving image data (or video data). The interface 610 may transfer the image data received from the processor 120 to the graphics memory 620 or the controller 640.

[0129] Graphics memory 620 may store image data received via interface 610. For example, graphics memory 620 may buffer the received image data before transmitting it to another component (e.g., image processing module 630, gate driver 650, or source driver 660). According to embodiments, graphics memory 620 may transmit the stored image data to image processing module 630. Image processing module 630 may process the image data to improve its quality. According to various embodiments, display driving circuitry 600 may include one or more image processing modules 630. According to embodiments, image processing module 630 may transmit processed image data to gate driver 650 or source driver 660.

[0130] The controller 640 controls the operation of the display driving circuit 600. The controller 640 may also include a timing controller for signal synchronization during image data processing. According to an embodiment, the controller 640 can transmit control signals corresponding to the screen refresh rate to the gate driver 650 or the source driver 660.

[0131] The gate driver 650 or source driver 660 (or data driver) can operate under the control of the controller 640. The gate driver 650 can operate by scanning scan lines of pixels connected to the display panel 690. The gate driver 650 can transmit scan signals through the scan lines. The source driver 660 can drive scan lines of pixels connected to the display panel 690.

[0132] A touch controller 670 (or touch IC) controls a touch layer included in the display panel 690. The touch controller 670 controls the touch layer to detect touch input or hover input at a predetermined location on the display panel 690. A digitizer controller 680 (or digitizer IC) controls a digitizer module 695 included (or located) below the display panel 690. The digitizer controller 680 controls the digitizer module 695 to detect digitizer input (e.g., pen input) at a predetermined location on the display panel 690.

[0133] The display panel 690 may include a plurality of pixels arranged in a matrix shape, and scan signal lines and data signal lines corresponding to the plurality of pixels may be connected to the display driving circuit 600. A touch layer (or touch sensor) may be included in the display panel 690. The digitizer module 695 may be an input device for reading coordinates (coordinates are analog data) and inputting drawings or graphics designed in digital form.

The flexible display of the electronic device 101 (e.g., Figure 1 The display module 160 may include a metal mesh-shaped touch TX / RX electrode pattern. The display module 160 may include a first housing (e.g., Figure 2a and Figure 2b The first region corresponding to the first shell 210 in the first shell (e.g., Figure 2a and Figure 2b The first region A1) and the second region extending from the first region A1 (e.g., Figure 2a and Figure 2b The second region A2), and the second region is housed in the second shell (e.g., Figure 2a and Figure 2b The rear surface of the second housing 230 or the front surface of the second housing 230 is exposed to the outside of the first housing 210 as the second housing 230 moves.

[0136] In the absence of input, the touch controller 700 can sense the E-field quantity generated by a power signal (e.g., voltage) driven in a specific frequency band on the TX electrode pattern using the RX electrode pattern. When finger input occurs, the E-field quantity signal coupled to the RX electrodes can be reduced. The signal sensed by the RX electrodes can be converted into a digital signal by an analog-to-digital converter (ADC) via touch filters 710 and 720 of the touch controller 700 and stored in an internal register. The value stored in the register can be transferred to the processor (e.g., ...). Figure 1 The processor 120 calculates the coordinate information using the TSP firmware. Each of touch filters 710 and 720 may include a low-pass filter or a demodulator. Touch filters 710 or 720 may be connected to the RX electrode pattern, respectively. The processor 120 may apply different configuration values ​​(or parameters) to touch filters 710 and 720 based on changes in the state of the electronic device 101.

[0137] According to various embodiments, when the electronic device 101 is in a turned-off state (e.g., Figure 4a In the off state 410, the processor 120 may apply the first touch filter to the first area A1 of the display module 160. The off state 410 may correspond to the state in which the second housing 230 is included (accommodated) in the first housing 210 of the electronic device 101.

[0138] According to various embodiments, when the electronic device 101 is in an intermediate state (e.g., Figure 4b In the intermediate state 430, the processor 120 may apply a first touch filter to the first region 431 of the display module 160, a second touch filter to the second region 433 of the display module 160, and a third touch filter to the third region 435 of the display module 160. The intermediate state 430 may indicate a state in which a portion of the second housing 230 is exposed to the outside of the first housing 210. In the intermediate state 430, portions of the first region A1 and the second region A2 of the display module 160 may be exposed externally (e.g., via a first direction or the front surface of the electronic device 101), and another portion of the second region A2 (e.g., via a first direction or the front surface of the electronic device 101) may be exposed. Figure 4b 440 in the middle may face a direction opposite to the first region A1 (e.g., a second direction or the rear surface of the electronic device 101).

[0139] According to various embodiments, in the intermediate state 430 of the electronic device 101, the processor 120 may be based on a second digitizer module (e.g., Figure 3 a and Figure 3 The processor 120 determines the touch filter to be applied to the third region 435 by using the driving method of the second digitizer module 303 (b). When the entire area of ​​the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101, the processor 120 may apply the third touch filter to the third region 435. Alternatively, when only a portion of the second digitizer module 303 (e.g., the second region 433) is driven in the intermediate state 430 of the electronic device 101, the processor 120 may apply either the first or the second touch filter to the third region 435. Alternatively, the processor 120 may apply the third touch filter to the third region 435 regardless of the driving state of the second digitizer module 303 in the intermediate state 430 of the electronic device 101.

[0140] The first region 431 may be a region exposed through the first housing 210 and not overlapping with the second housing 230. The first region 431 may be smaller than Figure 2a and Figure 2bThe first region A1 is the region in the first housing 210. The second region 433 can be the region where the second housing 230 is exposed to the outside of the first housing 210 and does not overlap with the first housing 210. The second region 433 can be... Figure 2a and Figure 2b The second region A2 corresponds to a portion (e.g., A2-1) and can be less than Figure 2a and Figure 2b The third region 435 can be the region where the first housing 210 and the second housing 230 overlap when the second housing 230 is housed inside the first housing 210. The third region 435 can be... Figure 2a and Figure 2b Part of the first region A1 or Figure 2a and Figure 2b The other part corresponds to the second region A2 in the display module 160. When the electronic device 101 is in the intermediate state 430, the processor 120 can apply different touch filters for each region of the display module 160 (e.g., the first region 431 to the third region 435).

[0141] According to various embodiments, in the open state of electronic device 101 (e.g., Figure 4c In the open state 450, the processor 120 can apply a first touch filter to the first region A1 of the display module 160 and apply a second touch filter to the second region A2 of the display module 160. The open state 450 can indicate that the second housing 230 is exposed to the outside of the first housing 210. The open state 450 can correspond to the state where the first region A1 and the second region A2 of the display module 160 are exposed externally (e.g., in a first direction or on the front surface of the electronic device 101). In the open state 450, the second region A2 can face the same first direction as the first region A1 (e.g., on the front surface of the electronic device 101).

[0142] Electronic devices according to various embodiments of the present disclosure (e.g., Figure 1 The electronic device 101 may include: a first housing (e.g., Figure 2a and Figure 2b The first housing 210); the second housing (e.g., Figure 2a and Figure 2b The second housing 230 is formed to be movable from the first housing and is either housed inside the first housing or exposed to the outside of the first housing; flexible displays (e.g., Figure 1 The display module 160 includes a first region (e.g., Figure 2a and Figure 2b The first region A1) and the second region (e.g., Figure 2a and Figure 2bThe second region A2), wherein the second region extends from the first region and is housed on the rear surface of the second housing, or is exposed to the outside of the first housing via the front surface of the second housing as the second housing moves; the first digitizer module (e.g., Figure 3 The first digitizer module 301 is located in the first housing and below the flexible display; the second digitizer module (e.g., Figure 3 The second digitizer module 303 is located in the second housing and is positioned below the first digitizer module when the second housing is housed inside the first housing; the memory (e.g., Figure 1 The memory 130 in the memory; and the processor (e.g., Figure 1 The processor 120 is operatively connected to the flexible display, the first digitizer module, the second digitizer module, or the memory, wherein the processor senses movement of the second housing relative to the first housing and configures different touch filters for each area of ​​the flexible display based on the movement of the second housing.

[0145] The first touch filter can be configured to have a value smaller than that of the second touch filter.

[0146] With a portion of the second housing housed inside the first housing and another portion of the second housing house exposed to the outside of the first housing, the processor can be configured to apply the first touch filter to the third region (e.g., Figure 4b In the first region 431), the second touch filter is applied to the fourth region (e.g., Figure 4b The second region 433), and the third filter is applied to the fifth region (e.g., Figure 4b The third region (435) in the middle.

[0147] The third region may be smaller than the first region of the flexible display, the fourth region may be smaller than the second region of the flexible display, and the fifth region may be formed by the overlapping of the first and second regions of the flexible display.

[0148] The first touch filter can be configured to have a value less than that of the second touch filter, and the third touch filter can be configured to have a value greater than the sum of the values ​​configured as the first touch filter and the values ​​configured as the second touch filter.

[0153] The processor can be configured to apply a touch filter to a flexible display and then update the touch baseline based on the touch filter.

[0154] Figure 8 This is a flowchart 800 illustrating a method of operating an electronic device according to various embodiments.

[0155] Reference Figure 8 In operation 801, a slidable electronic device (e.g., according to various embodiments) Figure 1 The processor of the electronic device 101 in the device (e.g., Figure 1 The processor 120 in the middle can detect the second housing (e.g., Figure 2a and Figure 2b The second housing 230) is relative to the first housing (e.g., Figure 2a and Figure 2bThe electronic device 101 may include a first housing 210 and a second housing 230. The second housing 230 may be housed within the first housing 210 in a closed state and exposed to the outside of the first housing 210 in an open state. The first housing 210 is the main housing of the electronic device 101 and may house various electrical and electronic components (such as a main circuit board or a battery). The first housing 210 may be fixed, and the second housing 230 may be configured to reciprocate a predetermined distance from the first housing 210 in a specified direction (e.g., the -x-axis direction D). The second housing 230 is slidable from the first housing 210. A sliding structure may be provided between the first housing 210 and the second housing 230 for sliding of the second housing 230.

[0156] In operation 803, the processor 120 can be positioned relative to the flexible display (e.g., based on the movement of the second housing 230) based on the movement of the flexible display. Figure 1 Each region of the display module 160 is configured with a touch filter. The display module 160 may include a first region (e.g., ...). Figure 2a and Figure 2b The first region A1) and the second region (e.g., Figure 2a and Figure 2b The second region A2 extends from the first region A1 and is contained within the rear surface of the second housing 230, or is exposed to the outside of the first housing 210 via the front surface of the second housing 230 as the second housing 230 moves. According to various embodiments, when the electronic device 101 is in an off state (e.g., ...), Figure 4a In the off state 410, the processor 120 may apply the first touch filter to the first area A1 of the display module 160. The off state 410 may correspond to the state in which the second housing 230 is included (accommodated) in the first housing 210 of the electronic device 101.

[0157] According to various embodiments, when the electronic device 101 is in an intermediate state (e.g., Figure 4bIn the intermediate state 430, the processor 120 may apply a first touch filter to the first region 431 of the display module 160, a second touch filter to the second region 433 of the display module 160, and a third touch filter to the third region 435 of the display module 160. The second touch filter f2 may be smaller than the first touch filter f1. The third touch filter f3 may be equal to or greater than the sum of the first touch filter f1 and the second touch filter f2. The intermediate state 430 may indicate a state in which a portion of the second housing 230 is exposed to the outside of the first housing 210. In the intermediate state 430, portions of the first region A1 and the second region A2 of the display module 160 may be exposed to the outside (e.g., a first direction or the front surface of the electronic device 101), and another portion of the second region A2 may face a direction opposite to that of the first region A1 (e.g., a second direction or the rear surface of the electronic device 101).

[0158] The first region 431 may be a region exposed through the first housing 210 and not overlapping with the second housing 230. The first region 431 may be smaller than Figure 2a and Figure 2b The first region A1 is the region in the first housing 210. The second region 433 can be the region where the second housing 230 is exposed to the outside of the first housing 210 and does not overlap with the first housing 210. The second region 433 can be... Figure 2a and Figure 2b The second region A2 corresponds to a portion (e.g., A2-1) and can be less than Figure 2a and Figure 2b The third region 435 can be the region where the first housing 210 and the second housing 230 overlap when the second housing 230 is housed inside the first housing 210. The third region 435 can be... Figure 2a and Figure 2b Part of the first region A1 or Figure 2a and Figure 2b The other part corresponds to the second region A2 in the display module 160. When the electronic device 101 is in the intermediate state 430, the processor 120 can apply different touch filters for each region of the display module 160 (e.g., the first region 431 to the third region 435).

[0159] According to various embodiments, in the intermediate state 430 of the electronic device 101, the processor 120 may be based on a second digitizer module (e.g., Figure 3 a and Figure 3The processor 120 determines the touch filter to be applied to the third region 435 by using the driving method of the second digitizer module 303 (b). When the entire region of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101, the processor 120 may apply the third touch filter to the third region 435. Alternatively, when only a portion of the second digitizer module 303 (e.g., the second region 433) is driven in the intermediate state 430 of the electronic device 101, the processor 120 may apply either the first or the second touch filter to the third region 435. Alternatively, the processor 120 may apply the third touch filter to the third region 435 regardless of the driving state of the second digitizer module 303 in the intermediate state 430 of the electronic device 101.

[0160] According to various embodiments, when the electronic device 101 is in an intermediate state 430, the processor may apply the value between the first touch filter f1 and the third touch filter f3 (an intermediate filter value between the first touch filter f1 and the third touch filter f3 (e.g., the second touch filter f2)) to a configuration region (e.g., a boundary region) between the first region 431 and the third region 435, and apply the filter value between the second touch filter f2 and the third touch filter f3 to a configuration region between the second region 433 and the third region 435. Optionally, the processor 120 may apply the first touch filter f1 (e.g., the larger value between the first touch filter f1 and the third touch filter f3) to a configuration region (e.g., a boundary region) between the first region 431 and the second region 435, and apply the second touch filter f2 (e.g., the larger value between the second touch filter f2 and the third touch filter f3) to a configuration region between the second region 433 and the third region 435.

[0161] According to various embodiments, in the open state of electronic device 101 (e.g., Figure 4c In the open state 450, the processor 120 can apply a first touch filter to the first region A1 of the display module 160 and apply a second touch filter to the second region A2 of the display module 160. The open state 450 can indicate that the second housing 230 is exposed to the outside of the first housing 210. The open state 450 can correspond to the state where the first region A1 and the second region A2 of the display module 160 are exposed externally (e.g., in a first direction or on the front surface of the electronic device 101). In the open state 450, the second region A2 can face the same first direction as the first region A1 (e.g., on the front surface of the electronic device 101).

[0162] In operation 805, processor 120 may update the touch baseline based on a configured touch filter. The touch baseline may refer to the capacitor value associated with touch detection. Considering that the touch layer can detect touch input based on changes in capacitor value, the AFE value may be distorted if the baseline is not equalized, and touch misidentification may occur due to noise. Processor 120 may update the touch baseline based on changes in the state of electronic device 101. For example, if the first touch filter is applied to the first region A1 of display module 160 in the off state 410 of electronic device 101, processor 120 may update the touch baseline of the first region A1 based on the first touch filter.

[0163] When the first touch filter is applied to the first region 431, the second touch filter is applied to the second region 433, and the third touch filter is applied to the third region 435 in the intermediate state 430 of the electronic device 101, the processor 120 can update the touch baseline of the first region 431 based on the first touch filter, update the touch baseline of the second region 433 based on the second touch filter, and update the touch baseline of the third region 435 based on the third touch filter. For example, when the first touch filter is applied to the first region 451 and the second touch filter is applied to the second region 453, in the open state 450 of the electronic device 101, the processor 120 can update the touch baseline of the first region 451 based on the first touch filter and update the touch baseline of the second region 453 based on the second touch filter.

[0164] In operation 807, processor 120 can detect touch input. The touch layer (or touch sensor) may be affected by external noise, display panel noise, or noise from the digitizer module. Touch misidentification may occur when the touch layer is affected by noise. By removing touch noise through operations 801 to 805, processor 120 can determine whether touch input from a user's finger or object (e.g., an electronic pen) is valid touch input and detect it as such. Touch detection is performed using a capacitance method, and therefore, valid touch input indicates that the touch input is based on user intent if the capacitance value generated by the touch input is greater than or equal to (or exceeds) a configured capacitance value. If the capacitance value generated by the touch input is less than (or less than or equal to) a configured capacitance value, processor 120 can determine that the capacitance value is a change due to external noise rather than user intent in the touch input.

[0165] Figure 9 This is a flowchart 900 illustrating a method for configuring a touch filter based on the movement of the housing of an electronic device, according to various embodiments. Figure 9 Can reflect Figure 8 Operation 803.

[0166] Reference Figure 9 In operation 901, a slidable electronic device (e.g., according to various embodiments) Figure 1 The processor of the electronic device 101 in the device (e.g., Figure 1 The processor 120 in the middle can detect the second housing (e.g., Figure 2a and Figure 2b The movement of the second housing 230 in the electronic device 101. The electronic device 101 may include the first housing (e.g., Figure 2a and Figure 2b The electronic device 101 comprises a first housing 210 and a second housing 230. The second housing 230 may be housed within the first housing 210 in a closed state and exposed to the outside of the first housing 210 in an open state. The first housing 210 may be fixed, and the second housing 230 may be configured to reciprocate a predetermined distance from the first housing 210 in a specified direction (e.g., the -x-axis direction D). The second housing 230 is slidable from the first housing 210. A sliding structure may be provided between the first housing 210 and the second housing 230 for sliding of the second housing 230. The processor 120 may perform operation 905 when the second housing 230 is moved and operation 903 when the second housing 230 is not moved.

[0167] With the second housing 230 not moved, in operation 903, the processor 120 can apply the first touch filter to the flexible display (e.g., Figure 1 The first area of ​​the display module 160 in the middle (e.g., Figure 2a and Figure 2b The first region A1 in the display module 160 may include a first region A1 and a second region (e.g., the first region A1 in the display module 160). Figure 2a and Figure 2b The second region A2 extends from the first region A1 and is contained within the rear surface of the second housing 230, or is exposed to the outside of the first housing 210 via the front surface of the second housing 230 as the second housing 230 moves. The absence of movement of the second housing 230 indicates the off state of the electronic device 101 (e.g., Figure 4a (The closed state 410). The closed state 410 corresponds to the state in which the second housing 230 is included (accommodated) within the first housing 210 of the electronic device 101. In the closed state 410, the processor 120 can apply a first touch filter to the first area A1 of the display module 160. The processor 120 can execute after applying the first touch filter. Figure 8 Operation 805.

[0168] In operation 905, if the second housing 230 is moved, the processor 120 can determine whether the second housing 230 has been moved to a configuration position. The configuration position can indicate that the second housing 230 can be moved from the first housing 210 to a position of maximum value. For example, the second housing 230 moving to the configuration position can instruct the electronic device 101 to switch to an open state (e.g., ...). Figure 4c (Open state 450). The processor 120 can perform operation 907 when the second housing 230 is moved to the configuration position, and perform operation 909 when the second housing 230 is not moved to the configuration position.

[0169] In operation 907, when the second housing 230 is moved to the configuration position, the processor 120 can apply a first touch filter to the first area A1 of the display module 160 and apply a second touch filter to the second area A2 of the display module 160. The movement of the second housing 230 to the configuration position can instruct the electronic device 101 to switch (or change) to an open state (e.g., ...). Figure 4c The open state 450 corresponds to a state in which the first region A1 and the second region A2 of the display module 160 are exposed externally (e.g., in a first direction or on the front surface of the electronic device 101). In the open state 450, the second region A2 may face the same first direction as the first region A1 (e.g., on the front surface of the electronic device 101). In the open state 450 of the electronic device 101, the processor 120 may apply a first touch filter to the first region A1 of the display module 160 and apply a second touch filter to the second region A2 of the display module 160.

[0170] In operation 909, when the second housing 230 is not moved to the configuration position, the processor 120 may apply a first touch filter to the first area 431 of the display module 160, a second touch filter to the second area 433 of the display module 160, and a third touch filter to the third area 435 of the display module 160. The fact that the second housing 230 is not moved to the configuration position may instruct the electronic device 101 to switch (or change) to an intermediate state (e.g., Figure 4b Intermediate state 430. Intermediate state 430 can indicate a state in which a portion of the second housing 230 is exposed to the outside of the first housing 210. In intermediate state 430, portions of the first region A1 and the second region A2 of the display module 160 (e.g., Figure 4b The second region 433) can be exposed externally (e.g., in the first direction or on the front surface of the electronic device 101), and another portion of the second region A2 (e.g., Figure 4b440 in the middle may face a direction opposite to the first region A1 (e.g., a second direction or the rear surface of the electronic device 101).

[0171] When the electronic device 101 is in an intermediate state 430, the processor 120 can apply different touch filters to each region of the display module 160 (e.g., first region 431 to third region 435). For example, in the intermediate state 430 of the electronic device 101, the processor 120 can apply a first touch filter to the first region 431 of the display module 160, a second touch filter to the second region 433 of the display module 160, and a third touch filter to the third region 435 of the display module 160. The second touch filter f2 can be smaller than the first touch filter f1. The third touch filter f3 can be equal to or greater than the sum of the first touch filter f1 and the second touch filter f2.

[0172] According to various embodiments, when the electronic device 101 is in intermediate state 430, the processor 120 may be based on a second digitizer module (e.g., Figure 3 a and Figure 3 The processor 120 determines the touch filter to be applied to the third region 435 by using the driving method of the second digitizer module 303 (b). When the entire area of ​​the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101, the processor 120 may apply the third touch filter to the third region 435. Alternatively, when only a portion of the second digitizer module 303 (e.g., the second region 433) is driven in the intermediate state 430 of the electronic device 101, the processor 120 may apply either the first or the second touch filter to the third region 435. Alternatively, the processor 120 may apply the third touch filter to the third region 435 regardless of the driving state of the second digitizer module 303 in the intermediate state 430 of the electronic device 101.

[0173] According to various embodiments, when the electronic device 101 is in an intermediate state 430, the processor may apply the value between the first touch filter f1 and the third touch filter f3 (an intermediate filter value between the first touch filter f1 and the third touch filter f3 (e.g., the second touch filter f2)) to a configuration region (e.g., a boundary region) between the first region 431 and the third region 435, and apply the filter value between the second touch filter f2 and the third touch filter f3 to a configuration region between the second region 433 and the third region 435.

[0182] Figure 10 This is a view illustrating another example of the setup of a digitizer module in an electronic device according to various embodiments.

[0183] Reference Figure 10 Electronic devices according to various embodiments (e.g., Figure 1 Electronic device 101) may include a flexible display (e.g., in the off state 1010) Figure 1The first digitizer module (e.g., the display module 160) below the first digitizer module (e.g., the display module 160) Figure 3 The first digitizer module 301 in the middle and the second digitizer module below the first digitizer module 301 (e.g., Figure 3 The second digitizer module 303 in the middle). The display module 160 may include a first area 1021 (e.g., Figure 2a and Figure 2b The first region A1) and the second region 1023 (e.g., Figure 2a and Figure 2b The second region A2). For example, in the closed state 1010, the first region 1021 may face a first direction (e.g., the front surface of the electronic device 101), and the second region 1023 may face a second direction (e.g., the rear surface of the electronic device 101). In the open state 1050, the first region 1021 and the second region 1023 may face the first direction (e.g., the front surface).

[0184] The position of the first region 1021 can be moved according to a change in the state of the electronic device 101 (e.g., from a closed state 1010 to an open state 1050). A second region 1023 may extend from the first region 1021, may be housed inside the first housing 1001 in the closed state 1010, and may be exposed to the outside of the first housing 1001 in the open state 1050. A first digitizer module 301 may be configured to correspond to the first region 1021, and a second digitizer module 303 may be fixed to the first housing 1001. In the closed state 1010 and the open state 1050, the first digitizer module 301 and the second digitizer module 303 may face a first direction (e.g., the front surface of the electronic device 101).

[0185] exist Figure 3 In the middle, the first region 1021 is fixed to the first housing (e.g., Figure 2a and Figure 2b The first housing 210 in the middle, so that even when the electronic device 101 is in the off state (e.g., Figure 3 The closed state 310) is changed to the open state (e.g., Figure 3 Even when in the open state (350), it is not moved. Figure 3 In this configuration, the first digitizer module 301 is fixed to the first housing 210 so that it is not moved even when the electronic device 101 is changed from the off state 310 to the on state 350.

[0186] Figure 10 The first region 1021 is not fixed to the first housing 1001, so that the first region can be moved when the electronic device 101 is changed from the off state 1010 to the on state 1050. Figure 10 In this configuration, when the electronic device 101 is changed to the open state 1050, the display module 160 including the first area 1021 and the second housing 1003 including the first digitizer module 301 can be moved. For example, depending on the change of the electronic device 101 to the open state 1050, the second housing 1003 can be moved from the first housing 1001 in a specified direction (e.g., the +x axis direction).

[0187] According to the change of electronic device 101 to open state 1050, the first digitizer module 301, which is configured to correspond to the first region 1021, can be moved from the first housing 1001 in a specified direction (e.g., the +x axis direction) in response to the first region 1021. When electronic device 101 is changed to open state 1050, the first digitizer module 301 is moved, and the second digitizer module 303, which is fixedly disposed in the first housing 1001, can be exposed to the first direction (e.g., the front surface of electronic device 101) through the second region 1023. In closed state 1010, the second digitizer module 303 can be disposed below the first digitizer module 301 to be unexposed, and when electronic device 101 is changed to open state 1050, the second digitizer module 303 can be exposed to the outside as the first digitizer module 301 disposed on the second digitizer module 303 moves.

Therefore, the scope of this disclosure should be construed as covering all changes or modifications derived from the technical concepts of this disclosure, in addition to the embodiments disclosed herein.
