[0025] In connection with the description of the drawings, the same or similar reference numerals may be used for identical or similar components.

[0026] Hereinafter, various embodiments disclosed in this document will be described with reference to the attached drawings. It should be understood that this is not intended to limit the various embodiments of this document to a specific form, but rather encompasses various modifications, equivalents, and / or alternatives of the present disclosure.

[0027] When using multiple input devices (e.g., stylus pens) on a flat display, the magnetic fields generated by each input device can interfere with each other, potentially causing malfunctions. To prevent malfunctions due to magnetic field interference, the electronic device can recognize and display only the magnetic field signals near the input signal of the pre-input digitizer as input signals. This allows the display to display only the input signal generated by one input device, even when two input devices are used.

[0028] In a foldable type electronic device, digitizer circuits disposed within a plurality of housings may share at least some of a plurality of signal output terminals of a control circuit. For example, among the plurality of housings included in the foldable type electronic device, a first digitizer disposed in a first housing and a second digitizer disposed in a second housing and / or a third housing may include a plurality of conductive lines for generating a signal for confirming a y-direction coordinate of an input device in each area, and the plurality of conductive lines of the first digitizer and the plurality of conductive lines of the second digitizer may be respectively connected to the same signal output terminal of the control circuit. As a result, when an axis (e.g., an X-axis) in the same direction is touched on a display of the electronic device by two input devices, two output values ​​may be input to the control circuit, which may cause an error.

[0029] In various embodiments of the present document, it is possible to provide various embodiments in which a plurality of input devices can be used by preventing interference of magnetic fields even when two different input devices are used for a first area and a second area of ​​a display distinguished by outfolding in a foldable electronic device.

According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module).

The first end of the 4b conductive line (253) may be connected to one of the output ends (234) corresponding to the output signals of Y00 to Y07 of the control circuit (230), and the second end of the 4b conductive line (253) may be connected to the reference end (233) (Yref) of the control circuit (230).

[0062] In a comparative example, among the plurality of signal output terminals included in the control circuit (230), the output terminal (232) corresponding to the output signals of X00 to X23 may be shared by the first conductive line (241) and the second conductive line (251). Therefore, when two different input devices are used together on the X-axis line of the display of the foldable electronic device (200), two output signals may be input to the control circuit (230), which may cause an error.

[0063] FIG. 3 is a drawing illustrating the structure of a digitizer included in a foldable electronic device (300) according to a comparative example.

[0066] In a comparative example, the first digitizer (350) may include a plurality of conductive lines (351, 352, 353) that generate signals for identifying coordinates of a position of an input device (e.g., a stylus pen) based on a magnetic field generated from the input device. The plurality of conductive lines (351, 352, 353) may each form an open loop, and currents may be induced in the plurality of conductive lines (351, 352, 353) according to changes in the magnetic field generated from the input device passing through the internal space of the open loop.

[0069] In a comparative example, the second digitizer (360) may include a plurality of conductive lines (361, 362, 363, 364) that generate signals for identifying coordinates of a position of the input device based on a magnetic field generated from the input device. The plurality of conductive lines (361, 362, 363, 364) may each form an open loop, and currents may be induced in the plurality of conductive lines (361, 362, 363, 364) according to changes in the magnetic field generated from the input device passing through the internal space of the open loop. The currents induced in the plurality of conductive lines (361, 362, 363, 364) or the voltages induced at both ends of the plurality of conductive lines (361, 362, 363, 364) may be used as signals for identifying coordinates of a position of the input device.

[0070] In a comparative example, the plurality of conductive lines (361, 362, 363, 364) may include a plurality of second conductive lines (361) that generate a signal for confirming the y-axis direction coordinate of the input device, a plurality of 5a conductive lines (362) that generate a signal for confirming the x-axis direction coordinate of the input device, a plurality of 5b conductive lines (363), and a plurality of 5c conductive lines (364).

A first end of the 5a conductive line (362) may be connected to a second end of the 4b conductive line (353), and a second end of the 5a conductive line (362) may be connected to one of the output terminals corresponding to the output signals of Y19 to Y21 of the control circuit (340). A first end of the 5b conductive line (363) may be connected to a reference terminal (Yref) of the control circuit (340), and a second end of the 5b conductive line (363) may be connected to one of the output terminals corresponding to the output signals of Y11 to Y18 of the control circuit (340).

[0072] In a comparative example, the third digitizer (370) may include a plurality of conductive lines (371, 362, 363) that generate signals for identifying coordinates of a position of the input device based on a magnetic field generated from the input device. The plurality of conductive lines (371, 372, 373) may each form an open loop, and currents may be induced in the plurality of conductive lines (371, 372, 373) according to changes in the magnetic field generated from the input device passing through the internal space of the open loop. The currents induced in the plurality of conductive lines (371, 372, 373) or the voltages induced at both ends of the plurality of conductive lines (371, 372, 373) may be used as signals for identifying coordinates of a position of the input device.

[0073] In a comparative example, the plurality of conductive lines (371, 372, 373) may include a plurality of third conductive lines (371) that generate a signal for identifying the y-axis direction coordinate of the input device, a plurality of 6a conductive lines (372) that generate a signal for identifying the x-axis direction coordinate of the input device, and a plurality of 6b conductive lines (373).

[0074] In a comparative example, a first end of a third conductive line (371) may be connected to a second end of a second conductive line (361), and a second end of the third conductive line (371) may be connected to a reference end (Xref) of a control circuit (340). A first end of a 6a conductive line (372) may be connected to a second end of a 5c conductive line (364), and a second end of the 6a conductive line (372) may be connected to a reference end (Yref) of a control circuit (340).

[0075] In a comparative example, among the plurality of signal output terminals included in the control circuit (340), the output terminals corresponding to the output signals of X00 to X23 may be shared by the first conductive line (351), the second conductive line (361), and the third conductive line (371). Therefore, when two different input devices are used together on the X-axis line of the display of the foldable electronic device (300), two output signals may be input to the control circuit (340), which may cause an error.

[0076] FIG. 4 is a drawing illustrating a method for a digitizer within an electronic device (300) to recognize a magnetic field when using multiple input devices, according to a comparative example. In the comparative example, the electronic device (300) may include a first housing (410), a second housing (420), and a third housing (430). A first digitizer (415) (e.g., the first digitizer (350) of FIG. 3) may be disposed inside the first housing (410) to confirm the position of the first input device (450) that touches the first area of ​​the display corresponding to the first housing (410) in the electronic device (300), and a second digitizer (425) may be disposed inside the second housing (420) and the third housing (430) to confirm the position of the second input device (460) that touches the second area of ​​the display corresponding to the second housing (420) and / or the third area of ​​the display corresponding to the third housing (430). In FIG. 3, one digitizer is depicted as being disposed inside the second housing (420) and the third housing (430), but depending on the embodiment, separate digitizers may be disposed inside the second housing (420) and the third housing (430).

[0077] Referring to FIG. 4, the first input device (450) and the second input device (460) can generate a signal including a resonant frequency by using a resonant circuit included in each input device. For example, when a current is applied to the first digitizer (415) in which a magnetic field is formed, a magnetic field can be formed. When the first input device (450) approaches the first digitizer (415) in which a magnetic field is formed, a current flows inside the first input device (450) due to the electromagnetic induction phenomenon, and a signal including a resonant frequency is formed through the resonant circuit in the first input device (450), and the first digitizer (415) can recognize this. The resonant circuit of the first input device (450) can be used to change the strength or frequency of the magnetic field according to the user's operating state. For example, the resonant circuit of the first input device (450) can provide various frequencies for recognizing a hovering input, a drawing input, a button input, or an erasing input. The first digitizer (415) can recognize various inputs by the first input device (450) by analyzing the signal formed through the first input device (450) and confirm the coordinates of the first input device (450). In Fig. 4, the second digitizer (425) can recognize the second input device (460) in the same manner as the first digitizer (415).

[0078] In a comparative example, when a second input device (460) approaches the second digitizer (425) while a first input device (450) is positioned adjacent to a first digitizer (415), magnetic field interference may occur in which a magnetic field formed between the first input device (450) and the first digitizer (415) and a magnetic field formed between the second input device (460) and the second digitizer (425) influence each other. This magnetic field interference may cause malfunction of the input devices (450, 460).

[0079] FIG. 5 is a drawing illustrating a deformable state of a foldable electronic device (500) according to an embodiment. According to an embodiment, the electronic device (500) is a multi-foldable type device that can be folded twice and may include three housings (e.g., a first housing, a second housing, or a third housing). In the electronic device (500), the first housing and the second housing may be connected through a first hinge portion, and the second housing and the third housing may be connected through a second hinge portion.

[0080] Referring to FIG. 5, the foldable electronic device (500) can be transformed into a folded state (510), an intermediate state (520), or an unfolded state (530) depending on a user's operation. The transformed state of the electronic device (500) can be determined by the angle between the first housing and the second housing and the angle between the second housing and the third housing.

[0081] In one embodiment, the folded state (510) may mean a state in which the foldable electronic device (500) is completely folded. For example, a portion including the first housing and the second housing of the electronic device (500) may be completely outfolded by the first hinge portion, and a portion including the second housing and the third housing of the electronic device (500) may be completely infolded by the second hinge portion. In the folded state (510), the first housing, the second housing, and the third housing of the electronic device (500) may be completely overlapped, so that only the first region (541) of the display (540) may be visually exposed to the outside. In the folded state (510), the second region (542) and the third region (543) may face each other by the infolding, and may not be exposed to the outside.

[0082] In one embodiment, the intermediate state (520) may refer to a state in which the foldable electronic device (500) is partially folded while maintaining a certain angle. For example, a portion including the first housing and the second housing of the electronic device (500) may be outfolded at a certain angle by the first hinge portion, and a portion including the second housing and the third housing of the electronic device (500) may be infolded at a certain angle by the second hinge portion. In the intermediate state (520), the entire area of ​​the display (540) may be visually exposed to the outside, but may be divided into a first area (541), a second area (542), and a third area (543) by the outfolding and the infolding.

[0083] In one embodiment, the unfolded state (530) may refer to a state in which the foldable electronic device (500) is fully unfolded. For example, the angle between the first housing and the second housing of the electronic device (500) and the angle between the second housing and the third housing may both represent approximately 180 degrees. In the unfolded state (530), since the display (540) maintains a flat shape, the entire area of ​​the display (540) is exposed to the outside and may be recognized as a single area.

[0084] FIGS. 6A and 6B are diagrams illustrating a method of forming a digitizer of a foldable electronic device (500) according to an embodiment. In an embodiment, the electronic device (500) may include a first housing (610), a second housing (620), and a third housing (630). In the electronic device (500), a display (e.g., a display (540) of FIG. 5) may be arranged across the first housing (610), the second housing (620), and the third housing (630), and one or more digitizers (615, 625, 635) may be arranged below the display.

[0085] Referring to FIG. 6A, the first housing (610) may include a first digitizer (615). The first digitizer (615) may be formed under a first area of ​​a display corresponding to the first housing (610) of the electronic device (500) and may recognize a touch input of an input device for the first area. In one embodiment, the second housing (620) and the third housing (630) may include a second digitizer (625). The second digitizer (625) may be formed under a second area of ​​a display corresponding to the second housing (620) of the electronic device (500) and a third area of ​​a display corresponding to the third housing (630) and may recognize a touch input of an input device for the second area and / or the third area. According to various embodiments, the digitizer for recognizing touch inputs for the second area and the third area may be formed separately as shown in FIG. 6b.

[0086] Referring to FIG. 6B, the second housing (620) may include a second digitizer (625), and the third housing (630) may include a third digitizer (635). In this case, the second digitizer (625) may be formed under a second area of ​​the display corresponding to the second housing (620), and the third digitizer (635) may be formed under a third area of ​​the display corresponding to the third housing (630).

[0087] In one embodiment, the electronic device (500) may support a bidirectional use mode when a specified condition is satisfied. For example, when the electronic device (500) includes a first housing (610) and a second housing (620) and is outfolded by a first hinge portion (640) at a predetermined angle (e.g., 90±15 degrees) so that one side of the first housing (610) touches the floor, and a second housing includes a second housing (620) and a third housing (630) and is infolded by a second hinge portion (650) so that the back of the third housing (630) touches the floor, the bidirectional use mode may be set. When the bidirectional use mode is set, multiple users may use the electronic device (500) through the first area and the second area (and / or the third area) of the display separated by the outfolding. For example, in a bidirectional mode, a first user may use a first input device through a first area of ​​the display, and a second user may use a second input device through a second area and / or a third area of ​​the display. A method for recognizing multiple input devices in a bidirectional mode according to various embodiments is described with reference to FIG. 7.

[0088] FIG. 7 is a diagram illustrating a method for a digitizer in a foldable electronic device (500) to recognize a magnetic field when a plurality of input devices are used, according to one embodiment. Referring to FIG. 7, a first input device (450) and a second input device (460) can generate a signal including a resonant frequency by using a resonant circuit included in each input device. For example, when a current is applied to the first digitizer (615) in which a magnetic field is formed, a magnetic field can be formed. When the first input device (450) approaches the first digitizer (615) in which a magnetic field is formed, a current flows inside the first input device (450) due to an electromagnetic induction phenomenon, and a signal including a resonant frequency is formed through the resonant circuit inside the first input device (450), and the first digitizer (615) can recognize this. The first digitizer (615) can analyze the signal formed through the first input device (450) to recognize various inputs by the first input device (450) and confirm the coordinates of the first input device (450). For another example, when current is applied to the second digitizer (625), a magnetic field is formed, and when the second input device (460) approaches the second digitizer (625) in which the magnetic field is formed, a current flows inside the second input device (460) due to the electromagnetic induction phenomenon, and a signal can be formed through the resonance circuit inside the second input device (460). The second digitizer (625) can analyze the signal formed through the second input device (460) to recognize various inputs by the second input device (460) and confirm the coordinates of the second input device (460).At this time, since the electronic device (500) is in a state where the portion including the first housing (610) and the second housing (620) is outfolded at a predetermined angle (e.g., 90±15 degrees), the direction of the magnetic field formed between the first input device (450) and the first digitizer (615) and the direction of the magnetic field formed between the second input device (460) and the second digitizer (625) are orthogonal to each other, so that interference of the magnetic fields does not occur, and thus, bidirectional use through the first area and the second area of ​​the display can be enabled.

[0089] According to various embodiments, the electronic device (500) may set a predetermined area including a first hinge portion (640) between a first area and a second area of ​​a display separated by an outfolding when a two-way use mode is set as a common display area (710). The common display area (710) is an area where magnetic field interference may occur when the first area and the second area of ​​the display are used together, and may be set to display status information such as the date, time, or battery without recognizing an input device.

[0090] FIG. 8 is a drawing illustrating the structure of a digitizer included in an electronic device (500) according to an embodiment. In FIG. 8, the electronic device (500) is a multi-foldable type device that can be folded twice and may include three housings (e.g., a first housing, a second housing, or a third housing). In the electronic device (500), the first housing and the second housing may be connected through a first hinge portion, the second housing and the third housing may be connected through a second hinge portion, and the three housings may be overlapped by a folding motion.

[0091] Referring to FIG. 8, the electronic device (500) may include a first PBA (810), a second PBA (820), a third PBA (830), a control circuit (840), a first digitizer (850), a second digitizer (860), a third digitizer (870), a first FPCB (855), a second FPCB (865), a third FPCB (875), a first C2C FPCB (880), or a second C2C FPCB (890).

[0092] In one embodiment, the first PBA (810), the first digitizer (850), and the first FPCB (855) may be positioned in the first housing of the electronic device (500).

In FIG. 8, the control circuit (840) is illustrated as being positioned on the second PBA (320), but the number or arrangement of the control circuits (840) is not limited thereto and may be configured in various ways. The first C2C FPCB (880) may be arranged to electrically connect the first PBA (810) and the second PBA (820), and the second C2C FPCB (890) may be arranged to electrically connect the second PBA (820) and the third PBA (830).

[0093] In one embodiment, the first digitizer (850) may include a plurality of conductive lines (851, 852, 853) that generate signals for identifying coordinates of a position of an input device based on a magnetic field generated from the input device (e.g., a stylus pen). Each of the plurality of conductive lines (851, 852, 853) may form an open loop, and currents may be induced in the plurality of conductive lines (851, 852, 853) according to changes in the magnetic field generated from the input device passing through the internal space of the open loop. The currents induced in the plurality of conductive lines (851, 852, 853) or the voltages induced at both ends of the plurality of conductive lines (851, 852, 853) may be used as signals for identifying coordinates of a position of the input device that has touched a first area of ​​a display corresponding to the first housing.

[0094] In one embodiment, the plurality of conductive lines (851, 852, 853) may include a plurality of first conductive lines (851) that generate a signal for identifying a first direction (e.g., y-axis direction) coordinate of the input device, a plurality of 4a conductive lines (852) that generate a signal for identifying a second direction (e.g., x-axis direction) coordinate of the input device, and a plurality of 4b conductive lines (853). For example, the plurality of first conductive lines (851) may include twelve first conductive lines corresponding to output signals from X24 to X35. The plurality of 4a conductive lines (852) may include eight 4a conductive lines corresponding to output signals from Y22 to Y29, and the plurality of 4b conductive lines (853) may include four 4b conductive lines corresponding to output signals from Y19 to Y21.

[0095] In one embodiment, a first end of a first conductive line (851) may be connected to a reference end (Xref) of a control circuit (840), and a second end of the first conductive line (851) may be connected to one of the output ends corresponding to output signals of X24 to X35 of the control circuit (840). A first end of a 4a conductive line (852) may be connected to one of the output ends corresponding to output signals of Y22 to Y29 of the control circuit (840), and a second end of the 4a conductive line (852) may be connected to a reference end (Yref) of the control circuit (840). A first end of a 4b conductive line (853) may be connected to a reference end (Yref) of the control circuit (840), and a second end of the 4b conductive line (853) may be connected to a first end of a 5a conductive line (862).

[0096] In one embodiment, the second digitizer (860) may include a plurality of conductive lines (861, 862, 863, 864) that generate a signal for identifying coordinates of a position of the input device based on a magnetic field generated from the input device. The plurality of conductive lines (861, 862, 863, 864) may each form an open loop, and currents may be induced in the plurality of conductive lines (861, 862, 863, 864) according to a change in the magnetic field generated from the input device passing through an internal space of the open loop. The currents induced in the plurality of conductive lines (861, 862, 863, 864) or the voltages induced at both ends of the plurality of conductive lines (861, 862, 863, 864) may be used as signals for identifying coordinates of a position of the input device.

[0097] In one embodiment, the plurality of conductive lines (861, 862, 863, 864) may include a plurality of second conductive lines (861) that generate a signal for identifying a y-axis direction coordinate of the input device, a plurality of 5a conductive lines (862) that generate a signal for identifying an x-axis direction coordinate of the input device, a plurality of 5b conductive lines (863), and a plurality of 5c conductive lines (864).

[0099] In one embodiment, the third digitizer (870) may include a plurality of conductive lines (871, 862, 863) that generate signals for identifying coordinates of a position of the input device based on a magnetic field generated from the input device. Each of the plurality of conductive lines (871, 872, 873) may form an open loop, and currents may be induced in the plurality of conductive lines (871, 872, 873) according to changes in the magnetic field generated from the input device passing through the internal space of the open loop. The currents induced in the plurality of conductive lines (871, 872, 873) or the voltages induced at both ends of the plurality of conductive lines (871, 872, 873) may be used as signals for identifying coordinates of a position of the input device.

[0100] In one embodiment, the plurality of conductive lines (871, 872, 873) may include a plurality of third conductive lines (871) that generate a signal for identifying a y-axis direction coordinate of the input device, a plurality of 6a conductive lines (872) that generate a signal for identifying an x-axis direction coordinate of the input device, and a plurality of 6b conductive lines (873).

The plurality of 6a conductive lines (872) may include three 6a conductive lines corresponding to output signals from Y08 to Y10, and the plurality of 6b conductive lines (872) may include eight 6b conductive lines corresponding to output signals from Y00 to Y07.

[0101] In one embodiment, a first end of a third conductive line (871) may be connected to a second end of a second conductive line (861), and a second end of the third conductive line (871) may be connected to a reference end (Xref) of a control circuit (840).

[0102] In one embodiment, unlike the comparative example of FIG. 3, the first conductive line (851) of the first digitizer (850) may not share an output terminal corresponding to the output signals X00 to X23 of the control circuit (840) with the second conductive line (861) of the second digitizer (860) and the third conductive line (871) of the third digitizer (870), but may be independently connected to an output terminal corresponding to the output signals X24 to X35. In this case, the induced current flowing in the first conductive line (851) may be transmitted to the control circuit (840) as one of the output signals X24 to X35, and the induced current flowing in the second conductive line (861) and the third conductive line (871) may be transmitted to the control circuit (840) as one of the output signals X00 to X23.

For example, even if two different input devices are used together in the area of ​​the display corresponding to the first housing and the area of ​​the display corresponding to the second / third housing, the two output signals can be input to the control circuit (840) through independent channels, respectively. According to various embodiments, the electronic device (500) may be configured to additionally include an independent control circuit for the first digitizer (850) together with the control circuit (840).

[0110] In FIG. 10, the control circuit (840) is illustrated as being placed on the second PBA (320), but the number or arrangement of the control circuits (840) is not limited thereto and may be configured in various ways, and the wiring of the digitizer (910) may also be changed depending on the arrangement of the control circuit (840).

[0111] FIG. 11 is a drawing illustrating the use of an input device when the electronic device (500) is in a folded state, according to one embodiment.

[0112] Referring to FIG. 11, when the electronic device (500) is in a completely folded state, a portion of the electronic device (500) including the first housing and the second housing can be completely outfolded based on the A axis, and a portion of the electronic device (500) including the second housing and the third housing can be completely infolded based on the B axis. In the folded state, among the entire area of ​​the display (1110) arranged across the first housing, the second housing, and the third housing, only the first area (1111) distinguished by the outfolding is visually exposed to the outside, and the second area (1112) and the third area (1113) that are infolded are folded to face each other, so that they cannot be exposed to the outside. In this case, the electronic device (500) can reduce current consumption by activating only the digitizer positioned under the first area (1111) among the entire area of ​​the display (1110) to an on state, and controlling the digitizers positioned under the second area (1112) and the third area (1113) to an off state.

[0113] FIG. 12 is a drawing illustrating the use of an input device when the electronic device (500) is in an unfolded state, according to one embodiment.

[0114] Referring to FIG. 12, when the electronic device (500) is fully unfolded, the display (1110) may be flat. In the unfolded state, the entire area of ​​the display (1110) is visually exposed to the outside and can be used as a single area, and a digitizer corresponding to the entire area of ​​the display (1110) can be activated in an on state. In this case, since the electronic device (500) can recognize a signal generated by a single input device (1210), a single user can independently use the entire area of ​​the display (1110).

[0115] FIG. 13 is a diagram illustrating a bidirectional usage mode when an electronic device (500) is in an intermediate state, according to one embodiment.

[0116] Referring to FIG. 13, when the housings of the electronic device (500) are in an intermediate state where they are partially folded while maintaining a certain angle, a bidirectional use mode may be provided. For example, when a portion including the first housing and the second housing of the electronic device (500) is outfolded at a certain angle (e.g., 90±15 degrees) so that one side of the first housing touches the floor, and a portion including the second housing and the third housing is infolded so that the rear side of the third housing touches the floor, a bidirectional use mode may be set. When the bidirectional use mode is set, multiple users can use the electronic device (500) through the first area (1111) and the second area (1112) (and / or the third area (1113)) of the display separated by the outfolding.

[0117] In one embodiment, when the bidirectional use mode is set by the user, the electronic device (500) automatically applies the bidirectional digitizer use mode so that two different input devices (1210, 1220) can be used in both directions of the first area (1111) and the second area (1112) (and / or the third area (1113)). For example, when the electronic device (500) detects a specified input by the user (e.g., a setting input of the bidirectional use mode through a menu screen displayed on the display, a voice command for setting the bidirectional use mode, or a gesture input specified in response to the bidirectional use mode), the electronic device (500) automatically applies the bidirectional digitizer use mode so that a user interface that allows the use of different input devices (1210, 1220) in the first area (1111) and the second area (1112) (and / or the third area (1113)) can be displayed.

[0118] In one embodiment, when a bidirectional digitizer use mode is additionally set after a bidirectional use mode is set by a user, the electronic device (500) may use two different input devices (1210, 1220) in both directions of the first area (1111) and the second area (1112) (and / or the third area (1113)). For example, when an additional input for setting the bidirectional digitizer use mode by the user is detected after the bidirectional use mode is set, or when an application associated with a digitizer function is executed in both the first area (1111) and the second area (1112), the electronic device (500) may apply the bidirectional digitizer use mode and display a user interface that allows the use of different input devices (1210, 1220) in the first area (1111) and the second area (1112), respectively.

[0119] In one embodiment, the electronic device (500) may set a predetermined area between the first area (1111) and the second area (1112) as a shared display area (1115) while the two-way use mode is set. Status information such as date, time, or battery may be displayed in the shared display area (1115). According to various embodiments, the size of the shared display area (1115) may be adjusted by a user's touch input. For example, the electronic device (500) may visually display the shared display area (1115) by enlarging or reducing it in response to a user's touch input on a boundary portion of the shared display area (1115).

[0120] FIG. 14 is a diagram illustrating a bidirectional use mode when the electronic device (500) is in an unfolded state, according to one embodiment. According to various embodiments, a bidirectional use mode may be provided in a limited manner even when the electronic device (500) is in a fully unfolded state.

[0121] In one embodiment, when the electronic device (500) is in an unfolded state and a two-way use mode and a two-way digitizer use mode are set by the user, the electronic device (500) may display user interfaces that enable the use of different input devices (1210, 1220) in the first area (1111) and the second area (1112) (and / or the third area (1113)). At this time, the electronic device (500) may set a predetermined area between the first area (1111) and the second area (1112) as a common display area (1115) and display status information such as date, time, or battery in the common display area (1115).

[0122] FIG. 15 is a diagram illustrating a function of moving an object (1510) in a first area (1111) to a second area (1112) when a two-way use mode is set, according to one embodiment. According to various embodiments, the electronic device (500) may move at least one object (1510) included in the first area (1111) to the second area (1112) while the two-way use mode is set.

[0123] Referring to FIG. 15, when a designated input for at least one object (1510) is detected by a first input device (1210) having main user authority set, the electronic device (500) may move the at least one object (1510) to a second area (1112).

The first application may include an application related to handwriting input, document work, or drawing work using an input device. In one embodiment, the electronic device (500) may display first data (1611) in response to a touch input by a first input device (1210) on the first execution screen (1610) while also displaying the first data (1611) on a second execution screen (1620) in the second area (1112).

According to various embodiments, when collaborative work or simultaneous signatures of two users are required, the electronic device (500) may simultaneously display data (e.g., first data (1611)) corresponding to a touch input on the first area (1111) and data (e.g., second data (1621)) corresponding to a touch input on the second area (1112) in the first area (1111) and the second area (1112) through a two-way use mode.

[0126] FIG. 17 is a diagram illustrating a function of sharing a screen displayed in a second area (1112) with a first area (1111) when a two-way use mode is set, according to one embodiment. According to various embodiments, the electronic device (500) may copy a screen displayed in a second area (1112) and display it in the first area (1111) while the two-way use mode is set.

[0127] Referring to FIG. 17, when a designated input for a screen (1710) displayed in a second area (1112) is detected by a first input device (1210) having main user authority set, the electronic device (500) may copy the screen (1710) and display it in the first area (1111). The designated input may include a touch input in which the screen (1710) in the second area (1112) is selected by the first input device (1210) and then dragged to the common display area (1115). In one embodiment, the electronic device (500) may recognize that the screen (1710) is selected when the screen (1710) in the second area (1112) is touched by the first input device (1210) or when the screen (1710) is touched a predetermined number of times while a button of the first input device (1210) is pressed.

[0128] According to various embodiments, the electronic device (500) may provide a function to share a screen displayed in a first area (1111) with a second area (1112). For example, when the electronic device (500) detects an input of dragging a screen displayed in the first area (1111) to a shared display area (1115) after the screen is selected by a first input device (1210) having main user permissions set, the electronic device (500) may copy the selected screen and display it in the second area (1112). The electronic device (500) may set and change the main user permissions according to the user's settings while operating in a two-way use mode.
