Description

Slidable electronic device having digitizer separation structure and touch driving method of slidable electronic device

Technical Field

Various embodiments of the present disclosure provide a slidable electronic device having a digitizer separation structure, and a touch driving method of the slidable electronic device.

Background

With the development of digital technology, various types of electronic devices such as Personal Digital Assistants (PDAs), electronic notebooks, smartphones, tablet Personal Computers (PCs), wearable apparatuses have been widely used. Electronic devices may have limited size for portability, thus limiting the size of the display. Accordingly, in recent years, various types of electronic devices that provide an extended screen through multiple displays have been developed.

For example, multiple displays are included to provide an extended screen through the multiple displays. As another example, electronic devices are designed such that the size of a screen gradually increases in a display and such that various services are provided to a user through a larger screen.

Recent electronic devices may have form factors such as multiple display (e.g., dual display) devices (e.g., foldable, rollable, or slidable). The foldable device may comprise a foldable (or bendable) display (e.g., a foldable display) or a flexible display, and may be folded or unfolded for use. The crimpable device or slidable device may include a flexible display and crimp and receive the flexible display in a rear surface of the slidable device or extend the flexible display to a front surface for use.

A conventional electronic device that includes a display having a specified size includes one digitizer layer and one touch layer on the display. Conventional electronic devices may include a touch layer below the display and a digitizer layer below the touch layer. The new form factor slidable electronic device may include a flexible display and a touch layer in a front surface of the flexible display. The touch layer is bendable and thus may be arranged in one layer corresponding to the flexible display. However, the digitizer layer is inflexible and thus difficult to arrange in one layer corresponding to a flexible display.

The first area A1 may be fixed to the first housing 210, and the second area 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 closed state of the electronic apparatus 101, the first area A1 may face a first direction (e.g., a front surface), and the second area A2 may be accommodated in a rear surface of the second case 230 and face a second direction (e.g., a rear surface). In the case where the second area A2 is accommodated in the rear surface of the second case 230, the second area A2 may not be visually exposed. Alternatively, in the case where the rear surfaces of the first and second cases 210 and 230 are formed of transparent covers, even if the second area A2 is received in the rear surface of the second case 230, the second area A2 may be visually exposed through the rear surfaces of the first and second cases 210 and 230.

For example, the second area A2 may be a bendable portion that changes according to the state of the electronic device 101, and may be referred to as other terms (such as a bendable area or a bendable section). 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 according to the movement (e.g., sliding movement) of the second housing 230 with respect to the first housing 210. The second area A2 may include an area that is accommodated in a side area of the electronic device 101 or a rear surface of the second case 230 in the closed state of the electronic device 101. The side area may correspond to the first side surface 205 extending from the first area A1 to the second area A2 of the display module 160. The second side surface 207 opposite to the first side surface 205 may include a plate 211 of the first case 210, and a portion (e.g., a first area A1) of the display module 160 may be mounted on one surface of the plate 211. The first side surface 205 and the second side surface 207 may mean side surfaces corresponding to long lengths of two parallel side surfaces of the electronic device 101.

The key input device 270 may be included in a third side surface (e.g., an upper side surface of the electronic apparatus 101) corresponding to a short length of the two parallel side surfaces of the electronic apparatus 101. A microphone, speaker, etc. may be included in the fourth side surface (e.g., the underside surface of the electronic device 101) or in the second side surface 207 corresponding to the short length of the two parallel side surfaces of the electronic device 101. According to an embodiment, the key input device 270 may be included in the second side surface 207 or the fourth side surface of the housing 210. Depending on the appearance or use status, the electronic device 101 may be designed to omit the described key input means 270 or further comprise one or more key input means. In an embodiment, the electronic apparatus 101 may include a key input device not described above, for example, a home key button or a touch pad disposed around the home key button. According to another embodiment, at least part of the key input device 270 may be disposed on an area of the first housing 210.

The first camera module 261 (e.g., the camera module 180 of fig. 1) may be included in the first area A1 of the display module 160 or the first case 210. For example, the first camera module 261 may be aligned at an opening (e.g., a via or recess) formed on the first area A1 and located inside the electronic device 101. External light may penetrate the opening and a partial region of the transparent cover overlapping 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 in an interior 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 on the area of the display module 160 facing the sensor module may not be necessary.

The first case 210 and the second case 230 may form part of the second area A2 of the rear surface of the electronic device 101 using a transparent cover. The transparent cover may serve to protect the display module 160 from the outside, and may be implemented by, for example, a flexible member 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., camera module 180 in fig. 1) on a rear surface of the electronic device 101.

The first camera module 261 or the plurality of camera modules 262, 263, and 264 may have different characteristics (e.g., viewing angle) and include, for example, a dual camera or a three-phase camera. In some embodiments, the plurality of camera modules 262, 263, and 264 may include lenses having different perspectives, and the electronic device 101 may be controlled based on user selections to change the camera modules executing in the electronic device 101. As another 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, for example, as part of a sensor module (not shown) (e.g., sensor module 176 in fig. 1). The location of the first camera module 261 or the plurality of camera modules 262, 263, and 264 may be changed according to the implementation of the electronic device 101.

Fig. 2b illustrates a front view 209 and a rear view 208 in an open state of the electronic device, according to various embodiments.

Fig. 2b may illustrate a state (e.g., an open state) in which the second housing 230 of the electronic device 101 is moved from the first housing 210, which may correspond to a state in which the size of the display module 160 exposed to the front surface of the electronic device 101 is increased. In the opened state of the electronic device 101, the display module 160 exposed to the front surface of the electronic device 101 may correspond to the first area A1 and the second area A2. In the open state of the electronic device 101, the first area A1 and the second area A2 may face in a first direction (e.g., a front surface). In the opened state of the electronic device 101, the second area A2 may be exposed through the front surface of the second case 230 or through the first side surface 205 of the electronic device 101 and the front surface of the second case 230.

The open state may correspond to a state in which the second housing 230 is maximally moved from the first housing 210, for example, a state in which the second housing is maximally moved in a first direction (e.g., -x-axis direction). The open state may mean a fully open state. The intermediate state may indicate a state between a closed state (see, e.g., fig. 2 a) and an open state (see, e.g., fig. 2 b). The intermediate state may indicate a state in which the second housing 230 may be further moved from the first housing 210. For example, the portion of the second area A2 exposed through the front surface of the electronic device 101 in the intermediate state may be smaller than the portion of the second area A2 exposed through the front surface of the electronic device 101 in the open state. The other portion A2-2' of the second area A2 exposed through the rear surface of the electronic device 101 in the intermediate state may be larger than the other portion A2-2 of the second area A2 exposed through the front surface of the electronic device 101 in the open state. The intermediate state may include multiple phases (e.g., phases 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 may be changed as much as the distance the second housing 230 is moved from the first housing 210.

Although it is described in the drawings that another portion A2-2 of the second area A2 is received in a side surface or a rear surface of the second case 230 in the opened state, in the opened state of the electronic device 101, the first area A1 and the second area A2 of the display module 160 may all be exposed through a front surface of the electronic device 101, and the display module 160 may not be exposed through a rear surface of the electronic device 101. This is merely an implementation problem and does not limit the present disclosure.

According to various embodiments, in the opened state of the electronic apparatus 101, a portion of the second area A2 may be exposed through the front surface of the second case 230, and another portion of the second area A2 may be accommodated in the side surface or the rear surface of the second case 230. For example, a portion of the second area A2 (e.g., a2 '+a2-1) exposed through the front surface of the electronic device 101 may include a side area A2' corresponding to the first side surface 205 and a portion A2-1 of the second area A2. In the opened state of the electronic apparatus 101, another portion A2-2 of the second area A2 may be accommodated in a side surface or a rear surface of the second case 230. Alternatively, in an intermediate state of the electronic apparatus 101, a portion (e.g., a2' +a2-1) of the second area A2 may be exposed through the front surface of the electronic apparatus 101, and another portion A2-2 of the second area A2 may be accommodated in the rear surface of the second case 230.

According to various embodiments, the electronic device 101 may detect the state of the electronic device 101 through the use of a sensor module (e.g., the sensor module 176 in fig. 1). For example, the electronic device 101 may detect whether the electronic device 101 is in the off state, the intermediate state, or the on state based on the sensing signal detected by the sensor module 176. In the case of the intermediate state of the electronic device 101, the electronic device 101 may detect how much the second housing 230 is moved from the second housing 230 according to the sensing signal. Alternatively, the electronic apparatus 101 may detect how much the second housing 230 moves from the second housing 230 based on the sliding structure.

According to various embodiments, in the case where the display module 160 is moved a configured distance by an external force, the electronic apparatus 101 may move (e.g., transition from a closed state to an open state, or transition from an open state to a closed state) the second housing 230 with respect to the first housing 210 due to an elastic structure included in the sliding structure without further external force (e.g., a semiautomatic sliding operation). According to an embodiment, in the case where a signal is generated through the key input device 270 included in the electronic apparatus 101, the electronic apparatus 101 may move (e.g., transition 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) with respect to the first housing 210 through a driving device (such as a motor) connected to the display module 160. For example, in the case where a signal is generated by a hardware button or a software button provided via a screen, the electronic device 101 may be converted from the off state to the on state (or intermediate state) or from the on state (or intermediate state) to the off state.

Although fig. 2a and 2b illustrate examples in which the size of the display of the electronic device 101 is increased in the-x-axis direction (e.g., left direction), the size of the display of the electronic device 101 may be increased in the +x-axis direction (e.g., right direction), the +y-axis direction (e.g., upward direction), or the-y-axis direction (e.g., downward direction). That is, the size of the display of the electronic device 101 may be increased in the horizontal direction, may be expanded in the left direction or the right direction, or may be expanded in both the left direction and the right direction. That is, the size of the display of the electronic device 101 may be increased in the vertical direction, may be expanded in the upward direction or the downward direction, or may be expanded in both the upward direction and the downward direction. Hereinafter, an example in which the size of the display increases in the left direction is described, but it is merely an implementation problem and does not limit the present disclosure.

Referring to fig. 3, a slidable electronic device (e.g., electronic device 101 in fig. 1) according to various embodiments can include a first digitizer module 301 under a flexible display (e.g., display module 160 in fig. 1) and a second digitizer module 303 under the first digitizer module 301 in a closed state 310. The closed state 310 of the drawing may show a cross-sectional view of a side surface corresponding to a short length of two parallel side surfaces of the electronic device 101 (e.g., an upper side surface or a lower side surface of the electronic device 101).

According to an embodiment, the electronic device 101 may detect magnetic field signals including resonant frequencies generated from a stylus pen through the first digitizer module 301 and the second digitizer module 303 using an electromagnetic resonance (EMR) method. For example, when alternating current is applied through a plurality of coils of the first digitizer module 301 and the second digitizer module 303, current may flow through coils inside a stylus pen adjacent to the first digitizer module 301 and the second digitizer module 303 according to an electromagnetic induction law, a signal including a resonance frequency may be formed through a resonance circuit inside the stylus pen, and the first digitizer module 301 and the second digitizer module 303 may detect the resonance frequency. The resonant circuit may include at least one coil, an inductor, and/or an electronic component such as a capacitor. According to an embodiment, the resonant circuit may be used to change the strength or frequency of the electromagnetic field depending on the operational state of the user. For example, the resonant circuit may provide various frequencies to identify a hover input, a drawing input, a button input, or an erase input.

The closed state 310 may correspond to a state in which the second housing (e.g., the second housing 230 in fig. 2a and 2 b) is included (housed) in the first housing (e.g., the first housing 210 in fig. 2a and 2 b) of the electronic device 101. In the closed state 310, the second housing 230 may be completely inserted into the first housing 210 such that the second housing 230 is not exposed to the outside. In the closed state 310, only a first region (e.g., the first region A1 in fig. 2a and 2 b) of the display module 160 may be exposed to the outside (e.g., the first direction or the front surface of the electronic device 101), and a second region (e.g., the second region A2 in fig. 2a and 2 b) of the display module 160 may not be exposed to the outside. In the closed state 310, the second region A2 may face in a second direction (e.g., a rear surface of the electronic device 101) opposite the first direction (e.g., a front surface of the electronic device 101). The first housing 210 may correspond to a main housing of the electronic device 101 and may include a processor (e.g., the processor 120 of fig. 1), a main circuit board 315 including a memory (e.g., the memory 130 of fig. 1), or a battery (e.g., the battery 189 of fig. 1).

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. In fig. 3, the first housing 210 may be fixed, and the second housing 230 may have a form in which an area corresponding to the second housing 230 is exposed when extended. The second digitizer module 303 may have a form that is fixed to an inner support of the second housing 230 and is exposed together when the second housing 230 moves. For example, the digitizer has inflexible properties, so the digitizer module (or layer) can be split 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 (coordinates 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 can identify coordinates (e.g., X and Y coordinates) corresponding to a touch pen's contact location on the display module 160. Hereinafter, the display module 160 will be described as facing upward (e.g., in a direction opposite to the direction of gravity) in the closed state 310 as an example. However, the description may not limit the disclosure.

In the off state 310, the first digitizer module 301 can be disposed under at least a portion of the display module 160 (or on a rear surface). In the closed state 310, a sliding structure (or member) 305 may be included under at least another portion of the display module 160. The sliding structure 305 (or a crimpable hinge structure) may correspond to a structure for moving the second housing 230 relative to the first housing 210. In the off state 310, the second digitizer module 303 may be disposed below the first digitizer module 301. That is, in the off state 310, the first digitizer module 301 may be disposed below (or on the rear surface of) the display module 160, and the second digitizer module 303 may be disposed below the first digitizer module 301. This is merely an implementation problem and the description of the drawings does not limit the present 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 (lattice).

In the off state 310, a first distance d1 (or length) (e.g., first distance d1 in fig. 4 c) between the display module 160 and the first digitizer module 301 may be different from a second distance d2 (e.g., second distance d2 in fig. 4 c) between the display module 160 and the second digitizer module 303. 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> d 1). For example, the second digitizer module 303 can be a longer distance (e.g., a second distance d 2) from the display module 160 than the first digitizer module 301 is from the display module 160. The first digitizer module 301 may be a shorter distance (e.g., a first distance d 1) from the display module 160 than the second digitizer module 303. The first distance d1 between the display module 160 and the first digitizer module 301 may indicate a distance from a window of contact touch input of the display module 160 to a rear surface of the first digitizer module 301. A second distance d2 between the display module 160 and the second digitizer module 303 may indicate a distance from a window of contact touch input of the display module 160 to a rear surface of the second digitizer module 303.

According to various embodiments, in the open state 350, the electronic device 101 may include a first digitizer module 301 under a first area A1 of the display module 160 corresponding to the first housing 210 and a second digitizer module 303 under a second area A2 of the display module 160 corresponding to the second housing 230. The open state 350 of the drawing may show a cross-sectional view of a side surface corresponding to a short length of two parallel side surfaces of the electronic device 101 (e.g., an upper side surface or a lower side surface 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 opened state 350, the second housing 230 may be maximally moved to the outside of the first housing 210 such that the second housing 230 is exposed to the outside. The open state 350 may correspond to a state in which the first area A1 and the second area A2 of the display module 160 are exposed through the outside (e.g., the first direction or the front surface of the electronic device 101). In the open state 350, the second area A2 may face the same first direction (e.g., the front surface of the electronic device 101) as the first area A1.

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

In the open state 350, a first distance d1 (or length) between the display module 160 and the first digitizer module 301 may be different than 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, the second digitizer module 303 is disposed in the second housing 230, the second housing 230 is formed to be received inside the first housing 210, and the second digitizer module 303 is disposed under the first digitizer module 301, the first distance d1 may be shorter than the second distance d2. The second digitizer module 303 may be a longer distance (e.g., a second distance d 2) from the display module 160 than the first digitizer module 301 is from the display module 160. The first digitizer module 301 may be a shorter distance (e.g., a first distance d 1) from the display module 160 than the second digitizer module 303. The first distance d1 between the display module 160 and the first digitizer module 301 may indicate a distance from a window of contact touch input of the display module 160 to a rear surface of the first digitizer module 301. A second distance d2 between the display module 160 and the second digitizer module 303 may indicate a distance from a window of contact touch input of the display module 160 to a rear surface of the second digitizer module 303. According to an embodiment, having a height difference (e.g., a difference between a first distance d1 and a second distance d 2) between the first digitizer module 301 and the second digitizer module 303, a step compensation layer may be provided between the second digitizer module 303 and the sliding structure (grid).

Fig. 4a is a diagram illustrating an example of applying a touch filter in an off state of an electronic device according to various embodiments.

Referring to fig. 4a, a slidable electronic device (e.g., electronic device 101 in fig. 1) according to various embodiments may apply a first touch filter to a first region 411 (e.g., first region A1 in fig. 2a and 2 b) of a flexible display (e.g., display module 160 in fig. 1) in a closed state 410. The closed state 410 may correspond to a state in which the second housing (e.g., the second housing 230 in fig. 2a and 2 b) is included (housed) in the first housing (e.g., the first housing 210 in fig. 2a and 2 b) of the electronic device 101. In the closed state 410, the second housing 230 may be completely inserted into the first housing 210 such 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 may 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., the second area A2 in fig. 2a and 2 b) may not be exposed to the outside. The first area 411 in fig. 4a may correspond to the first area A1 in fig. 2a and 2 b. Alternatively, the first region 411 in fig. 4a may be the same as the first region A1 in fig. 2a and 2 b.

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 (e.g., first digitizer module 301 in fig. 3a and 3 b) or a second digitizer module (e.g., second digitizer module 303 in fig. 3a and 3 b) below the display panel. Alternatively, the display module 160 may include an additional (add-on) method for attaching a separate Touch Screen Panel (TSP) to the display, an on-cell method for patterning on a lower portion of a polarizing layer or an upper portion of an encapsulation layer, or an in-cell method for disposing on a Thin Film Transistor (TFT) substrate inside the display, and may include the first digitizer module 301 or the second digitizer module 303 under the display panel. The first digitizer module 301 may be disposed in the first housing 210 to correspond to the first region A1 of the display module 160. The second digitizer module 303 may be disposed in the second housing 230 to correspond to the second region A2 of the display module 160.

The touch layer (or touch sensor) may be affected by external noise, noise of the display panel, or noise of the digitizer module. In the case where the touch layer is affected by noise, touch misrecognition may occur. Furthermore, where, for example, the electronic device 101 includes two digitizer modules (e.g., a first digitizer module 301 and a second digitizer module 303), the touch layer may be affected differently depending on the arrangement of the two digitizer modules. Since the arrangement structure of the two digitizer modules is changed according to the movement of the second housing 230 with respect to the first housing 210 in the present disclosure, a method for reducing touch noise based on the movement of the second housing 230 may be provided.

In the off state 410 where the first digitizer module 301 is disposed below the display module 160 and the second digitizer module 303 is disposed below the first digitizer module 301, the electronic device 101 may apply a first touch filter to a first area A1 of the display module 160. The first touch filter may be a filter applied to an electronic device including one digitizer module and one touch layer instead of a structure including two digitizer modules. The first filter may be preconfigured by a first distance d1 between the display module 160 and the first digitizer module 301.

The first touch filter may equalize the touch baselines corresponding to the first area 411 in order to remove touch noise. Touch baseline may mean a capacitor value associated with touch detection. In view of the touch layer detecting touch input based on capacitor value changes, in the event that the baseline is not equalized, the Analog Front End (AFE) value may be distorted and touch misrecognition may occur due to the effects of noise. Since only the first region 411 is exposed to the outside in the off state 410 of the electronic device 101, the first touch filter may be applied to the first region 411 based on the first distance d1 between the display module 160 and the first digitizer module 301. In the case that the first touch filter is applied to the first area 411, the touch baseline of the first area 411 may be updated based on the first touch filter.

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 region 411 is exposed to the outside in the off state 410 of the electronic device 101, the first digitizer module 301 may be used and the second digitizer module 303 may not be used. The second digitizer module 303 is used in a case where the second region A2 is exposed, and thus may not be used in a case where only the first region 411 is exposed to the outside. The electronic device 101 may not drive the second digitizer module 303 that is not in use in order to minimize touch noise due to the second digitizer module 303. Alternatively, in order to minimize noise interference due to 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.

Fig. 4b is a diagram illustrating an example of applying a touch filter in an intermediate state of an electronic device, according to various embodiments.

Referring to fig. 4b, in the intermediate state 430, the electronic device 101 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 (e.g., the second region 433) of the second housing 230 is exposed to the outside of the first housing 210. In the intermediate state 430, portions of the first area A1 and the second area A2 (e.g., the second area 433) of the display module 160 may be exposed through the outside (e.g., the first direction or the front surface of the electronic device 101), and the other portion 440 of the second area A2 may face in a direction opposite to the first area A1 (e.g., the second direction or the rear surface of the electronic device 101).

The first region 431 may be a region exposed through the first housing 210 and not overlapping the second housing 230. The first region 431 may be a region smaller than the first region A1 in fig. 2a and 2 b. For example, the first region A1 in fig. 2a and 2b may refer to a region obtained by combining the first region 431 and the third region 435 of fig. 4 b. The second region 433 may be a region where the second case 230 is exposed to the outside of the first case 210 and does not overlap the first case 210. The second region 433 may correspond to a portion (e.g., A2-1) of the second region A2 in fig. 2a and 2b, and may be a region smaller than the second region A2 in fig. 2a and 2 b. The third region 435 may be a region where the first case 210 overlaps the second case 230 when the second case 230 is received inside the first case 210. The third region 435 may correspond to a portion of the first region A1 in fig. 2a and 2b or another portion of the second region A2 in fig. 2a and 2 b.

For example, the second region 433 may be a portion (e.g., A2-1) of the second region A2 of the display module 160 that the user may contact when the second housing 230 moves. The third region 435 may be a portion of the first region A1 of the display module 160 that is user-accessible and another portion of the second region A2 of the display module 160 that is not user-accessible. Alternatively, 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.

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 a 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, 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.

Since the user can contact the display module 160 and the second digitizer module 303 corresponding to the second region 433 is driven, the second region 433 can be affected by the second digitizer module 303. For example, the second touch filter f2 may be configured according to 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 may be smaller than the first touch filter f1.

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, which may correspond to the third region 435, may be driven, and the second digitizer module 303, which corresponds to the third region 435, may or may not be driven. The third region 435 can be affected by the first digitizer module 301 and the second digitizer module 303. The third touch filter may be configured based on the first touch filter and the second touch filter. For example, 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. For example, in the intermediate state 430, the electronic device 101 may drive the entire second digitizer module 303 or may not drive a partial region (e.g., the third region 435) of the second digitizer module 303. In the case of driving the second digitizer module 303 corresponding to the third region 435, the electronic device 101 can apply a third touch filter f3 to the third region 435. Alternatively, in the case where the second digitizer module 303 corresponding to the third region 435 is not driven, the electronic device 101 may apply the first touch filter f1 or the second touch filter f2 to the third region 435. Alternatively, the electronic device 101 may apply the third touch filter f3 to the third region 435 regardless of the driving of the second digitizer module 303 corresponding to the third region 435. This is merely an implementation problem and does not limit the present disclosure.

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

According to various embodiments, the 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 the electronic device 101 from a closed state to an intermediate state or an open state or a state transition of the electronic device 101 from an open state to an intermediate state or a closed state. The electronic device 101 may update the touch baseline based on state transitions (changes) of the electronic device 101.

For example, in the case of applying the first touch filter to the first region 431, the touch baseline of the first region 431 may be updated based on the first touch filter. In case that the second touch filter is applied to the second region 433, the touch baseline of the second region 433 may be updated based on the second touch filter. In the case of applying the third touch filter to the third region 435, the touch baseline of the third region 435 may be updated based on the third touch filter. Alternatively, in the case that the first touch filter or the second touch filter is applied to the third region 435, the touch baseline of the third region 435 may be updated based on the first touch filter or the second touch filter.

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

The electronic device 101 may divide the first digitizer module 301 or the second digitizer module 303 into multiple regions and control a partial region to be sensed and control another partial region not to be sensed. For example, to minimize noise interference of the first digitizer module 301 and the second digitizer module 303 and reduce power consumption, in the intermediate state 430, the electronic device 101 may control the first digitizer module 301 and another portion of the second digitizer module 303 corresponding to the sensed second region 433 and control a partial region of the second digitizer module 303 corresponding to the third region 435 that will not be sensed corresponding to the first region 431 and the third region 435.

According to various embodiments, because actuation of the first digitizer module 301 or the second digitizer module 303 may cause touch noise, the electronic device 101 may apply different filters to the respective regions based on actuation of the first digitizer module 301 or the second digitizer module 303. For example, a first digitizer module 301 may be driven in a first region 431, a second digitizer module 303 may be driven in a second region 433, the first digitizer module 301 may be driven in a third region 435 and the second digitizer module 303 may not be driven, and the second digitizer module 303 may be disposed below the first digitizer module 301. Accordingly, the electronic device 101 may 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 value assigned to the first touch filter f1 may be smaller than the value of the second touch filter f2 and larger than the value of the third touch filter f 3.

According to various embodiments, in the intermediate state 430 of the electronic device 101, the electronic device 101 may determine a touch filter to be applied to the third region 435 based on a driving method of the second digitizer module 303. In the event that 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 a third touch filter to the third region 435. Alternatively, the electronic device 101 may apply the first touch filter or the second touch filter to the third region 435 in the event that only a partial region (e.g., the second region 433) of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101. Optionally, the electronic device 101 may apply a 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.

According to various embodiments, the electronic device 101 may apply a 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 f 2)) to a configuration region (e.g., a boundary region) between the first region 431 and the third region 435, and apply a 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. Alternatively, the electronic device 101 may apply the first touch filter f1 (e.g., a larger value between the first touch filter f1 and the third touch filter f 3) 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., a larger value between the second touch filter f2 and the third touch filter f 3) to a configuration region between the second region 433 and the third region 435.

Fig. 4c is a diagram illustrating an example of applying a touch filter in an open state of an electronic device according to various embodiments.

Referring to fig. 4c, in the open state 450, the electronic device 101 may apply a first touch filter to the first region 451 of the display module 160 and a second touch filter to the second region 453 of the display module 160. The open state 450 may indicate a state in which the second housing 230 is exposed to the outside of the first housing 210. In the opened state 450, the second housing 230 may be maximally moved to the outside of the first housing 210 such that the second housing 230 is exposed to the outside. The open state 450 may correspond to a state in which the first area A1 and the second area A2 of the display module 160 are exposed through the outside (e.g., the first direction or the front surface of the electronic device 101). In the open state 450, the second region A2 may face the same first direction (e.g., the front surface of the electronic device 101) as the first region A1.

In the open state 450, the first region 451 may be a region corresponding to the first housing 210, exposed to the outside (e.g., the first direction or the front surface of the electronic device 101) through the first housing 210, and not overlapping the second housing 230. The first region 451 may correspond to the first region A1 in fig. 2a and 2b, and may be the same as the first region A1. The second region 453 may be a region that corresponds to the second case 230, is exposed to the outside (e.g., the first direction or the front surface of the electronic device 101) through the second case 230, and does not overlap the first case 210. The second region 453 may correspond to the second region A2 in fig. 2a and 2b, and may be the same as the second region A2.

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 a 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 may be shorter than the second distance d2 (e.g., d2> d 1). Since the user can contact the display module 160 and the second digitizer module 303 corresponding to the second region 453 is driven, the second region 433 can be affected by the second digitizer module 303. For example, the second touch filter f2 may 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 d 2. The second touch filter f2 may be smaller than the first touch filter f1.

According to various embodiments, the 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 the electronic device 101 from a closed state to an open state or a state transition (change) of the electronic device 101 from an open state to a closed state. The electronic device 101 may update the touch baseline based on state transitions (changes) of the electronic device 101. For example, in the case of applying the first touch filter to the first area 451, the touch baseline of the first area 451 may be updated based on the first touch filter. In the case where the second touch filter is applied to the second region 453, the touch baseline of the second region 453 may be updated based on the second touch filter.

According to various embodiments, in the open state 450, the electronic device 101 may drive (e.g., open or enable) the first digitizer module 301 and may drive (e.g., open or enable) the second digitizer module 303. In the open state 450, the electronic device 101 can drive a first digitizer module 301 corresponding to a first region 431 and drive a second digitizer module 303 corresponding to a second region 433. Since actuation of the first digitizer module 301 or the second digitizer module 303 may cause touch noise, the electronic device 101 may apply different filters to the respective regions based on actuation of the first digitizer module 301 or the second digitizer module 303. For example, a first digitizer module 301 may be driven in a first region 451, a second digitizer module 303 may be driven in a second region 453, and the digitizer modules may not overlap each other in the first and second regions 451, 453. Accordingly, the electronic apparatus 101 may apply the first touch filter f1 to the first region 451 and the second touch filter f2 to the second region 453. The value allocated to the first touch filter f1 may be smaller than the value of the second touch filter f 2.

Fig. 5a is a diagram illustrating an example of applying a touch filter in an off state of an electronic device according to various embodiments.

Referring to fig. 5a, a first graph 510 may depict initial noise conditions in the case of a closed state (e.g., 410 in fig. 4 a) of a slidable electronic device (e.g., 101 in fig. 1) according to various embodiments. The closed state 410 may correspond to a state in which the second housing (e.g., the second housing 230 in fig. 2a and 2 b) is included (housed) in the first housing (e.g., the first housing 210 in fig. 2a and 2 b) of the electronic device 101. In the closed state 410, the second housing 230 may be completely inserted into the first housing 210 such that the second housing 230 is not exposed to the outside. In the closed state 410, only a first region (e.g., first region A1 in fig. 2a and 2b and first region 411 in fig. 4 a) of the flexible display (e.g., display module 160 in fig. 1) may be exposed through the outside (e.g., a first direction or a front surface of the electronic device 101), and a second region (e.g., second region A2 in fig. 2a and 2 b) of the display module 160 may not be exposed to the outside.

The y-axis of the first graph 510 may indicate raw data about touch noise, and the x-axis may correspond to the first region A1. Referring to the first graph 510, the initial touch noise (or touch sensitivity) in the off state 410 may vary for each of the first regions A1. The first digitizer module (e.g., the first digitizer module 301 of fig. 3) included in the first housing 210 may be driven, and the second digitizer module (e.g., the second digitizer module 303 of fig. 3) included in the second housing 230 may not be driven. The touch layer included in the display panel of the display module 160 may be affected by external noise, noise of the display panel, or noise of the digitizer module. Because 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 the first touch filter f1 to the first area A1 in the off state 410. In the case of applying the first touch filter f1 to the first area A1, touch noise of each area of the first area A1 may be equalized (e.g., smoothed or reduced to a value of "0") by uniformly correcting a touch baseline in response to the first area A1.

Fig. 5b is a diagram illustrating an example of applying a touch filter in an open state of an electronic device according to various embodiments.

Referring to fig. 5b, a second graph 520 may depict an initial noise condition in the case of an open state (e.g., 450 in fig. 4 c) of the electronic device 101. The open state 450 may indicate a state in which the second housing 230 is exposed to the outside of the first housing 210. In the opened state 450, the second housing 230 may be maximally moved to the outside of the first housing 210 such that the second housing 230 is exposed to the outside. The open state 450 may correspond to a state in which the first area A1 and the second area A2 of the display module 160 are exposed through the outside (e.g., the first direction or the front surface of the electronic device 101). In the open state 450, the second region A2 may face the same first direction (e.g., the front surface of the electronic device 101) as the first region A1.

The y-axis of the second graph 520 may indicate raw data about touch noise, and the x-axis may correspond to the first and second areas A1 and A2. Referring to the second graph 520, initial touch noise may differently occur in the first and second areas A1 and A2 in the open state 450. In the open state 450, the first digitizer module 301 included in the first housing 210 may be driven and the second digitizer module 303 included in the second housing 230 may be driven. In the open state 450, the first digitizer module 301 and the second digitizer module 303 may affect touch noise of the first area A1 and the second area A2. The electronic device 101 may apply the first touch filter f1 to the first area A1 and the second touch filter f2 to the second area A2 in the open state 450.

The third graph 530 depicts touch noise after the first touch filter f1 is applied to the first area A1 and the second touch filter f2 is applied to the second area A2 in the on state 450. In the case where different touch filters are applied to the first and second areas A1 and A2, touch noise of the first and second areas A1 and A2 may be equalized by uniformly correcting touch baselines in response to the first and second areas A1 and A2.

Fig. 5c is a diagram illustrating an example of applying a touch filter in an intermediate state of an electronic device according to various embodiments.

Referring to fig. 5c, a fourth graph 540 may depict an initial noise condition in the case of an intermediate state of the electronic device 101 (e.g., 430 in fig. 4 b). 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 area A1 and the second area A2 of the display module 160 (e.g., the second area 433 in fig. 4 b) may be exposed through the outside (e.g., the first direction or the front surface of the electronic device 101), and another portion of the second area A2 (e.g., 440 in fig. 4 b) may face in a direction opposite to the first area A1 (e.g., the second direction or the rear surface of the electronic device 101).

The y-axis of the fourth graph 540 may indicate raw data about touch noise, and the x-axis may correspond to the first region 431, the second region 433, and the third region 435 in fig. 4a to 4 c. The first region 431 may be a region exposed through the first housing 210 and not overlapping the second housing 230. The second region 433 may be a region where the second case 230 is exposed to the outside of the first case 210 and does not overlap the first case 210. The third region 435 may be a region where the first case 210 overlaps the second case 230 when the second case 230 is received inside the first case 210. Referring to the fourth graph 540, in the intermediate state 430, initial touch noise may be large in order of the third region 435, the first region 431, and the second region 433. Since touch noise is inversely proportional to distance, as the distance between the first digitizer module 301 or the second digitizer module 303 and the display module 160 increases, the touch noise may decrease.

For example, the second region 433 may correspond to a second distance d2 between the second digitizer module 303 and the display module 160, and the first region 431 may correspond to a 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> d 1). Further, 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, and the second digitizer module 303 corresponding to the third region 435 may not be driven. The third region 435 can be affected by the first digitizer module 301 and the second digitizer module 303.

The fifth graph 550 may depict touch noise after the first touch filter f1 is applied to the first through third regions 431 through 435. It can be recognized that in the case where only the first touch filter f1 is applied, there is touch noise with respect to the second region 433, and touch noise with respect to the third region 435 is relatively large. Since the touch noise is different for each region (e.g., first region 431 through third region 435) at the display module 160 in the intermediate state 430, the electronic device 101 may apply the touch filter differently for each region of the display module 160.

The sixth graph 560 may depict touch noise after the first touch filter f1 is applied to the first region 431, the second touch filter f2 is applied to the second region 433, and the third touch filter f3 is applied to the third region 435. In the intermediate state 430, the electronic device 101 may 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 a sum value of the first touch filter f1 and the second touch filter f 2.

Referring to fig. 6, a slidable electronic device (e.g., electronic device 101 of fig. 1) according to various embodiments may include a processor (e.g., processor 120 of fig. 1), display drive circuitry 600, touch controller 670, digitizer controller 680, display panel 690, or digitizer module 695. Although fig. 6 shows one digitizer module 695, the slidable electronic device 101 can include two digitizer modules (e.g., the first digitizer module 301 and the second digitizer module 303 in fig. 3). The slidably shaped electronic device 101 may include a flexible display (e.g., the display module 160 in fig. 1), and the display module 160 may include the display driving circuit 600 and the display panel 690.

The processor 120 may generate a user interface to be displayed on the display panel 690 and determine a screen refresh rate based on the generated user interface. Processor 120 may include a Graphics Processing Unit (GPU) and TSP firmware. The processor 120 may send control signals regarding screen refresh rates or pixel data (or image data) corresponding to the user interface to the display driving circuit 600 through the GPU. The processor 120 may calculate coordinate information acquired from the touch controller 670 by the TSP firmware.

The display driving circuit 600 (display driver integrated circuit (DDI)) may include an interface 610, a graphic 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 image data received from the processor 120 to the graphics memory 620 or the controller 640.

Graphics memory 620 may store image data received through interface 610. For example, the graphics memory 620 may perform buffering of received image data before transferring the image data to another component (e.g., the image processing module 630, the gate driver 650, or the source driver 660). According to an embodiment, the graphics memory 620 may transfer stored image data to the image processing module 630. The image processing module 630 may process the image data to improve the quality of the image data. According to various embodiments, the display drive circuit 600 may include one or more image processing modules 630. According to an embodiment, the image processing module 630 may transfer the processed image data to the gate driver 650 or the source driver 660.

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

The gate driver 650 or the source driver 660 (or the data driver) may operate according to the control of the controller 640. The gate driver 650 may operate by scanning scan lines connected to pixels of the display panel 690. The gate driver 650 may transmit a scan signal through a scan line. The source driver 660 may drive scan lines connected to pixels of the display panel 690.

The touch controller 670 (or touch IC) may control a touch layer included in the display panel 690. The touch controller 670 may control the touch layer to detect a touch input or a hover input for a predetermined location of the display panel 690. Digitizer controller 680 (or a digitizer IC) may control a digitizer module 695 included (or disposed) under display panel 690. Digitizer controller 680 may control digitizer module 695 to detect digitizer input (e.g., pen input) for a predetermined location of display panel 690.

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. Digitizer module 695 may be an input device for reading coordinates (coordinates are analog data) and inputting drawings or graphics designed in digital form.

Referring to fig. 7, a slidable electronic device (e.g., electronic device 101 of fig. 1) according to various embodiments may include a touch controller 700 (e.g., touch controller 670 of fig. 6). The flexible display of the electronic device 101 (e.g., the display module 160 in fig. 1) may include a touch TX/RX electrode pattern in the shape of a metal mesh. The display module 160 may include a first region (e.g., the first region A1 of fig. 2a and 2 b) corresponding to the first housing (e.g., the first housing 210 of fig. 2a and 2 b) and a second region (e.g., the second region A2 of fig. 2a and 2 b) extending from the first region A1, and the second region is received in a rear surface of the second housing (e.g., the second housing 230 of fig. 2a and 2 b) or is exposed to the outside of the first housing 210 as the second housing 230 moves through a front surface of the second housing 230.

Without input, touch controller 700 may sense an E-field amount generated by a power signal (e.g., voltage) driven at a particular frequency band on a TX electrode pattern with the RX electrode pattern. When finger input occurs, the E-field magnitude signal coupled to the RX electrode may be reduced. The signals sensed through the RX electrodes may pass through touch filters 710 and 720 of the touch controller 700 to be converted into digital signals through analog-to-digital converters (ADCs) and stored in internal registers. The values stored in the registers may be transferred to a processor (e.g., processor 120 in fig. 1) and calculated by the TSP firmware as coordinate information. Each of the touch filters 710 and 720 may include a low pass filter or a demodulator. Touch filter 710 or 720, respectively, may be connected to the RX electrode pattern. Processor 120 may apply different configuration values (or parameters) to touch filters 710 and 720 based on the state change of electronic device 101.

According to various embodiments, the processor 120 may apply the first touch filter to the first area A1 of the display module 160 with the electronic device 101 in an off state (e.g., the off state 410 in fig. 4 a). The closed state 410 may correspond to a state in which the second housing 230 is included (accommodated) in the first housing 210 of the electronic device 101.

According to various embodiments, with the electronic device 101 in an intermediate state (e.g., intermediate state 430 in fig. 4 b), 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 area A1 and the second area A2 of the display module 160 may be exposed through the outside (e.g., the first direction or the front surface of the electronic device 101), and another portion of the second area A2 (e.g., 440 in fig. 4 b) may face in a direction opposite to the first area A1 (e.g., the second direction or the rear surface of the electronic device 101).

According to various embodiments, in the intermediate state 430 of the electronic device 101, the processor 120 may determine the touch filter to be applied to the third region 435 based on a driving method of the second digitizer module (e.g., the second digitizer module 303 in fig. 3a and 3 b). In the event that the entire region of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101, the processor 120 can apply a third touch filter to the third region 435. Alternatively, the processor 120 may apply the first touch filter or the second touch filter to the third region 435 in the event that only a partial region (e.g., the second region 433) of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101. Optionally, the processor 120 can apply a 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.

The first region 431 may be a region exposed through the first housing 210 and not overlapping the second housing 230. The first region 431 may be a region smaller than the first region A1 in fig. 2a and 2 b. The second region 433 may be a region where the second case 230 is exposed to the outside of the first case 210 and does not overlap the first case 210. The second region 433 may correspond to a portion (e.g., A2-1) of the second region A2 in fig. 2a and 2b, and may be a region smaller than the second region A2 in fig. 2a and 2 b. The third region 435 may be a region where the first case 210 overlaps the second case 230 when the second case 230 is received inside the first case 210. The third region 435 may correspond to a portion of the first region A1 in fig. 2a and 2b or another portion of the second region A2 in fig. 2a and 2 b. With the electronic device 101 in the intermediate state 430, the processor 120 may apply a different touch filter for each region (e.g., the first region 431 through the third region 435) of the display module 160.

According to various embodiments, in the open state of the electronic device 101 (e.g., the open state 450 in fig. 4 c), the processor 120 may apply a first touch filter to the first area A1 of the display module 160 and a second touch filter to the second area A2 of the display module 160. The open state 450 may indicate a state in which the second housing 230 is exposed to the outside of the first housing 210. The open state 450 may correspond to a state in which the first area A1 and the second area A2 of the display module 160 are exposed through the outside (e.g., the first direction or the front surface of the electronic device 101). In the open state 450, the second region A2 may face the same first direction (e.g., the front surface of the electronic device 101) as the first region A1.

An electronic device (e.g., electronic device 101 in fig. 1) according to various embodiments of the disclosure may include: a first housing (e.g., first housing 210 in fig. 2a and 2 b); a second housing (e.g., second housing 230 in fig. 2a and 2 b) formed to be movable from the first housing and received inside the first housing or exposed to the outside of the first housing; a flexible display (e.g., display module 160 in fig. 1) comprising a first region (e.g., first region A1 in fig. 2a and 2 b) and a second region (e.g., second region A2 in fig. 2a and 2 b), wherein the second region extends from the first region and is received on a rear surface of the second housing or is exposed to an exterior of the first housing as the second housing moves past a front surface of the second housing; a first digitizer module (e.g., first digitizer module 301 in fig. 3) located in the first housing and below the flexible display; a second digitizer module (e.g., second digitizer module 303 in fig. 3) located in the second housing and below the first digitizer module in a state where the second housing is housed inside the first housing; a memory (e.g., memory 130 in fig. 1); and a processor (e.g., processor 120 in fig. 1) 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 a different touch filter for each region of the flexible display based on the movement of the second housing.

The processor may be configured to apply the first touch filter to the first region of the flexible display in a state in which the second housing is housed inside the first housing.

The processor may be configured to apply the first touch filter to the first region of the flexible display and apply the second touch filter to the second region in a state in which the second housing is exposed to an outside of the first housing.

The first touch filter may be configured to have a smaller value than the second touch filter.

In a state in which a portion of the second housing is received inside the first housing and another portion of the second housing is exposed to the outside of the first housing, the processor may be configured to apply the first touch filter to a third region (e.g., the first region 431 in fig. 4 b), apply the second touch filter to a fourth region (e.g., the second region 433 in fig. 4 b), and apply the third filter to a fifth region (e.g., the third region 435 in fig. 4 b).

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 first and second regions of the flexible display overlapping each other.

The first touch filter may be configured to have a value less than a value of the second touch filter, and the third touch filter may be configured to have a value greater than a sum of the value configured as the first touch filter and the value configured as the second touch filter.

The processor may be configured to control the first digitizer module to be driven and the second digitizer module not to be driven in a state in which the second housing is housed inside the first housing.

The processor may be configured to control the first digitizer module and the second digitizer module to be driven in a state in which the second housing is exposed to the outside of the first housing.

The processor may control the second digitizer module such that a partial region of the second digitizer module is not sensed in a state where a portion of the second housing is received inside the first housing and another portion of the second housing is exposed to the outside of the first housing.

The processor may control the second digitizer module such that a partial area of the second digitizer module corresponding to a partial area of the second housing received inside the first housing is not sensed and another partial area of the second digitizer module corresponding to another partial area of the second housing exposed outside the first housing is sensed.

The processor may be configured to apply a touch filter to the flexible display and then update the touch baseline based on the touch filter.

Fig. 8 is a flow chart 800 illustrating a method of operation of an electronic device, in accordance with various embodiments.

Referring to fig. 8, in operation 801, a processor (e.g., processor 120 in fig. 1) of a slidable electronic device (e.g., electronic device 101 in fig. 1) may detect movement of a second housing (e.g., second housing 230 in fig. 2a and 2 b) relative to a first housing (e.g., first housing 210 in fig. 2a and 2 b) according to various embodiments. The electronic device 101 may include a first housing 210 and a second housing 230, the second housing 230 may be accommodated within the first housing 210 in a closed state of the electronic device 101, and the second housing 230 may be exposed to the outside of the first housing 210 in an open state of the electronic device 101. The first housing 210 is a main housing of the electronic device 101, and can 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 be capable of reciprocating a predetermined distance from the first housing 210 in a designated direction (e.g., -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.

In operation 803, the processor 120 may configure a touch filter for each region of the flexible display (e.g., the display module 160 in fig. 1) based on the movement of the second housing 230. The display module 160 may include a first region (e.g., a first region A1 of fig. 2a and 2 b) and a second region (e.g., a second region A2 of fig. 2a and 2 b) extending from the first region A1 and received in a rear surface of the second housing 230 or exposed to the outside of the first housing 210 as the second housing 230 moves through a front surface of the second housing 230. According to various embodiments, the processor 120 may apply the first touch filter to the first area A1 of the display module 160 with the electronic device 101 in an off state (e.g., the off state 410 in fig. 4 a). The closed state 410 may correspond to a state in which the second housing 230 is included (accommodated) in the first housing 210 of the electronic device 101.

According to various embodiments, with the electronic device 101 in an intermediate state (e.g., intermediate state 430 in fig. 4 b), 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 a sum value of the first touch filter f1 and the second touch filter f 2. 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 and second areas A1 and A2 of the display module 160 may be exposed through the outside (e.g., the first direction or the front surface of the electronic device 101), and another portion of the second area A2 may face in a direction opposite to the first area A1 (e.g., the second direction or the rear surface of the electronic device 101).

According to various embodiments, in the intermediate state 430 of the electronic device 101, the processor 120 may determine the touch filter to be applied to the third region 435 based on a driving method of the second digitizer module (e.g., the second digitizer module 303 in fig. 3a and 3 b). In the event that the entire region of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101, the processor 120 can apply a third touch filter to the third region 435. Alternatively, the processor 120 may apply the first touch filter or the second touch filter to the third region 435 in the event that only a partial region (e.g., the second region 433) of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101. Alternatively, the processor 120 can 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.

According to various embodiments, with the electronic device 101 in the intermediate state 430, the processor may apply a 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 f 2)) to a configuration region (e.g., a boundary region) between the first region 431 and the third region 435, and apply a 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. Alternatively, the processor 120 may apply a first touch filter f1 (e.g., a larger value between the first touch filter f1 and the third touch filter f 3) to a configuration region (e.g., a boundary region) between the first region 431 and the second region 435, and a second touch filter f2 (e.g., a larger value between the second touch filter f2 and the third touch filter f 3) to a configuration region between the second region 433 and the third region 435.

In operation 805, the processor 120 may update the touch baseline based on the configured touch filter. Touch baseline may mean a capacitor value associated with touch detection. Considering that the touch layer may detect touch input based on capacitor value changes, the AFE value may be distorted and touch misrecognition may occur due to the influence of noise in case the baseline is not equalized. The processor 120 may update the touch baseline based on a change in state of the electronic device 101. For example, in the case where the first touch filter is applied to the first area A1 of the display module 160 in the off state 410 of the electronic device 101, the processor 120 may update the touch baseline of the first area A1 based on the first touch filter.

In the case where 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 may update the touch baseline of the first region 431 based on the first touch filter, the touch baseline of the second region 433 based on the second touch filter, and the touch baseline of the third region 435 based on the third touch filter. For example, in the case where a first touch filter is applied to the first zone 451 and a second touch filter is applied to the second zone 453, in the on state 450 of the electronic device 101, the processor 120 may update the touch baseline of the first zone 451 based on the first touch filter and the touch baseline of the second zone 453 based on the second touch filter.

In operation 807, the processor 120 may detect a touch input. The touch layer (or touch sensor) may be affected by external noise, noise of the display panel, or noise of the digitizer module. In the case where the touch layer is affected by noise, touch misrecognition may occur. Since the touch noise is removed through operations 801 through 805, the processor 120 may determine whether a touch input of a user finger or an object (e.g., an electronic pen) is a valid touch input and detect it as a touch input. Touch detection is performed by a capacitive method, and thus an active touch input may indicate that a determination of touch input is made according to a user's intent in the event that a capacitance value generated by the touch input is greater than or equal to (or exceeds) a configured capacitance value. In the case where the capacitance value generated by the touch input is less than (or less than or equal to) the configured capacitance value, the processor 120 may determine the capacitance value as a capacitance value change due to external noise instead of the touch input intended by the user.

Fig. 9 is a flow chart 900 illustrating a method for configuring a touch filter based on movement of a housing of an electronic device, in accordance with various embodiments. Fig. 9 may embody operation 803 of fig. 8.

Referring to fig. 9, in operation 901, a processor (e.g., processor 120 in fig. 1) of a slidable electronic device (e.g., electronic device 101 in fig. 1) may detect movement of a second housing (e.g., second housing 230 in fig. 2a and 2 b) according to various embodiments. The electronic device 101 may include a first housing (e.g., the first housing 210 in fig. 2a and 2 b) and a second housing 230, the second housing 230 may be housed within the first housing 210 in a closed state of the electronic device 101, and the second housing 230 may be exposed to the outside of the first housing 210 in an open state of the electronic device 101. The first housing 210 may be fixed, and the second housing 230 may be configured to be capable of reciprocating a predetermined distance from the first housing 210 in a designated direction (e.g., -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 if the second housing 230 is moved and operation 903 if the second housing 230 is not moved.

In the case where the second housing 230 is not moved, the processor 120 may apply a first touch filter to a first region (e.g., a first region A1 in fig. 2a and 2 b) of a flexible display (e.g., the display module 160 in fig. 1) in operation 903. The display module 160 may include a first region A1 and a second region (e.g., a second region A2 in fig. 2a and 2 b) that extends from the first region A1 and is received in a rear surface of the second housing 230 or is exposed to the outside of the first housing 210 as the second housing 230 moves through a front surface of the second housing 230. The case where the second housing 230 is not moved may indicate a closed state of the electronic device 101 (e.g., the closed state 410 in fig. 4 a). The closed state 410 may correspond to a state in which the second housing 230 is included (accommodated) in the first housing 210 of the electronic device 101. 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 processor 120 may perform operation 805 of fig. 8 after applying the first touch filter.

In operation 905, the processor 120 may determine whether the second housing 230 is moved to the configuration position in the case where the second housing 230 is moved. The configuration position may indicate a position where the second housing 230 may be moved from the first housing 210 to a maximum value. For example, movement of the second housing 230 to the configuration position may instruct the electronic device 101 to transition to an open state (e.g., the open state 450 in fig. 4 c). The processor 120 may perform operation 907 if the second housing 230 is moved to the configuration position and perform operation 909 if the second housing 230 is not moved to the configuration position.

In operation 907, in case the second housing 230 is moved to the configuration position, the processor 120 may apply the first touch filter to the first area A1 of the display module 160 and apply the second touch filter to the second area A2 of the display module 160. The movement of the second housing 230 to the configuration position may instruct the electronic device 101 to transition (or change) to an open state (e.g., the open state 450 in fig. 4 c). The open state 450 may correspond to a state in which the first area A1 and the second area A2 of the display module 160 are exposed through the outside (e.g., the first direction or the front surface of the electronic device 101). In the open state 450, the second region A2 may face the same first direction (e.g., the front surface of the electronic device 101) as the first region A1. In the open state 450 of the electronic device 101, the processor 120 may apply a first touch filter to the first area A1 of the display module 160 and a second touch filter to the second area A2 of the display module 160.

In operation 909, in case the second housing 230 is not moved to the configuration position, the processor 120 may apply the first touch filter to the first region 431 of the display module 160, the second touch filter to the second region 433 of the display module 160, and the third touch filter to the third region 435 of the display module 160. A condition in which the second housing 230 is not moved to the configuration position may instruct the electronic device 101 to transition (or change) to an intermediate state (e.g., intermediate state 430 in fig. 4 b). 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 area A1 and the second area A2 of the display module 160 (e.g., the second area 433 in fig. 4 b) may be exposed through the outside (e.g., the first direction or the front surface of the electronic device 101), and another portion of the second area A2 (e.g., 440 in fig. 4 b) may face in a direction opposite to the first area A1 (e.g., the second direction or the rear surface of the electronic device 101).

With the electronic device 101 in the intermediate state 430, the processor 120 may apply a different touch filter for each region (e.g., the first region 431 through the third region 435) of the display module 160. For example, in the intermediate state 430 of the electronic device 101, 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 a sum value of the first touch filter f1 and the second touch filter f 2.

According to various embodiments, with the electronic device 101 in the intermediate state 430, the processor 120 may determine a touch filter to be applied to the third region 435 based on a driving method of a second digitizer module (e.g., the second digitizer module 303 in fig. 3a and 3 b). In the event that the entire region of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101, the processor 120 can apply a third touch filter to the third region 435. Alternatively, the processor 120 may apply the first touch filter or the second touch filter to the third region 435 in the event that only a partial region (e.g., the second region 433) of the second digitizer module 303 is driven in the intermediate state 430 of the electronic device 101. Optionally, the processor 120 can apply a 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.

The method of operation of an electronic device (e.g., electronic device 101 in fig. 1) according to various embodiments of the present disclosure may include: the operation of detecting movement of a second housing (e.g., second housing 230 in fig. 2a and 2 b) of the electronic device and the operation of configuring a different filter for each region of a flexible display (e.g., display module 160 in fig. 1) of the electronic device based on movement of the second housing, wherein the second housing is formed to be movable from the first housing (e.g., first housing 210 in fig. 2a and 2 b) and to be received inside or exposed to the outside of the first housing, the electronic device may include a first digitizer module (e.g., first digitizer module 301 in fig. 3) disposed in the first housing and disposed below the flexible display and a second digitizer module (e.g., second digitizer module 303 in fig. 3) disposed below the first digitizer module in a state in which the second housing is received inside the first housing, and the flexible display may include a first region (e.g., first digitizer module 210 in fig. 2a and 2 b) and a second digitizer module 303 in fig. 2b extending from the first housing and a second housing in accordance with the movement of the first region and the second housing 2a and the exposed region in accordance with the second housing.

The operation of configuring may include: an operation of applying the first touch filter to the first region of the flexible display in a state where the second housing is accommodated inside the first housing.

The operation of configuring may include: an operation of applying a first touch filter to a first region of the flexible display and a second touch filter to a second region in a state where the second housing is exposed to an outside of the first housing, wherein the first touch filter is configured to have a value smaller than a value of the second touch filter.

The configuration operation may include the following operations: in a state in which a portion of the second housing is accommodated inside the first housing and another portion of the second housing is exposed to the outside of the first housing, the first touch filter is applied to the third region, the second touch filter is applied to the fourth region, and the third filter is applied to the fifth region, wherein the first touch filter is configured to have a value smaller than a value of the second touch filter, and the third touch filter is configured to have a value greater than a sum of the value configured as the first touch filter and the value configured as the second touch filter.

The method may further comprise the operations of: the first digitizer module is controlled to be driven and the second digitizer is controlled not to be driven in a state that the second housing is accommodated inside the first housing.

The method may further comprise the operations of: the first digitizer module and the second digitizer are controlled to be driven in a state where the second housing is exposed to the outside of the first housing.

The method may further comprise: in a state in which a portion of the second housing is housed inside the first housing and another portion of the second housing is exposed to the outside of the first housing, an operation of the second digitizer module is controlled such that a partial area of the second digitizer module corresponding to a partial area of the second housing housed inside the first housing is not sensed and another partial area of the second digitizer module corresponding to another partial area of the second housing exposed to the outside of the first housing is sensed.

The method may further comprise: an operation of updating the touch baseline based on the touch filter after the touch filter is applied to the flexible display.

Referring to fig. 10, an electronic device (e.g., electronic device 101 in fig. 1) according to various embodiments can include a first digitizer module (e.g., first digitizer module 301 in fig. 3) under a flexible display (e.g., display module 160 in fig. 1) and a second digitizer module (e.g., second digitizer module 303 in fig. 3) under first digitizer module 301 in an off state 1010. The display module 160 may include a first region 1021 (e.g., first region A1 in fig. 2a and 2 b) and a second region 1023 (e.g., second region A2 in fig. 2a and 2 b). For example, in the closed state 1010, the first region 1021 may face in a first direction (e.g., a front surface of the electronic device 101) and the second region 1023 may face in a second direction (e.g., a rear surface of the electronic device 101). In the open state 1050, the first region 1021 and the second region 1023 may face in a first direction (e.g., a front surface).

The position of the first region 1021 may be moved according to a state change of the electronic device 101 (e.g., from the closed state 1010 to the open state 1050). The 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. The first digitizer module 301 may be disposed to correspond to the first region 1021, and the 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 in a first direction (e.g., a front surface of the electronic device 101).

In fig. 3, the first region 1021 is fixed to a first housing (e.g., the first housing 210 in fig. 2a and 2 b) so as not to be moved even if the electronic device 101 is changed from a closed state (e.g., the closed state 310 in fig. 3) to an open state (e.g., the open state 350 in fig. 3). In fig. 3, the first digitizer module 301 is fixed to the first housing 210 so as not to be moved even if the electronic device 101 is changed from the closed state 310 to the open state 350.

The first region 1021 of fig. 10 is not fixed to the first housing 1001 so that the first region can be moved in the event that the electronic device 101 is changed from the closed state 1010 to the open state 1050. In fig. 10, in the case where the electronic device 101 is changed to the open state 1050, the display module 160 including the first region 1021 and the second housing 1003 including the first digitizer module 301 can be moved. For example, according to a change of the electronic apparatus 101 to the open state 1050, the second housing 1003 may be moved from the first housing 1001 in a specified direction (for example, +x-axis direction).

According to a change of the electronic device 101 to the open state 1050, the first digitizer module 301 configured to correspond to the first region 1021 may be moved from the first housing 1001 in a designated direction (e.g., the +x-axis direction) in response to the first region 1021. In the case where the electronic device 101 is changed to the open state 1050, the first digitizer module 301 is moved, and the second digitizer module 303 fixedly disposed in the first housing 1001 may be exposed to a first direction (e.g., a front surface of the electronic device 101) through the second region 1023. In the off state 1010, the second digitizer module 303 may be disposed below the first digitizer module 301 so as not to be exposed, and when the electronic device 101 is changed to the on state 1050, the second digitizer module 303 may be exposed to the outside as the first digitizer module 301 disposed on the second digitizer module 303 moves.

The embodiments disclosed in the specification and the drawings are provided as specific examples only, to easily explain technical features and to aid understanding of the present disclosure, and are not intended to limit the scope of the present disclosure. Accordingly, the scope of the present disclosure should be construed as covering all changes or modifications derived from the technical idea of the present disclosure, except for the embodiments disclosed herein.
