For example, a hall sensor and a magnetic material can detect the angle between the first housing and the second housing, and the angle between the second housing and the third housing by detecting an electrical change (e.g., a change in voltage) that occurs when the distance between the first housing and the second housing and the distance between the second housing and the third housing approaches or moves away. For example, an infrared sensor can detect the angle between the first housing and the second housing, and the angle between the second housing and the third housing by detecting a change in an infrared signal that occurs when the distance between the first housing and the second housing and the distance between the second housing and the third housing approaches or moves away. For example, the electromagnetic sensor can detect the angle between the first housing and the second housing and the angle between the second housing and the third housing by detecting the change in electromagnetic force caused by the distance between the first housing and the second housing and the distance between the second housing and the third housing getting closer or farther away.

[0065] In one embodiment, the sensor (376) can obtain information regarding the remaining capacity of the battery of the electronic device (101). For example, the sensor (376) can obtain information regarding the voltage that the battery provides to the electronic device (101).

For example, the second display may be arranged on the rear side of at least one of the housings. The second display may include a polarizing layer. The first display may include a color filter array instead of a polarizing layer.

[0069] In one embodiment, the display (360) may display a user interface. For example, the display (360) may display a user interface related to activating a battery saving mode. For example, the display (360) may display a user interface related to disabling a battery saving mode. For example, the display (360) may display a user interface for adjusting an area for displaying content.

[0070] According to one embodiment, the memory (330) may include instructions. The instructions may be executed by the processor (320).

For example, the processor (320) may control at least one of the memory (330), the display (360), and the sensor (376). The processor (320) may perform calculations in accordance with the instructions so that the electronic device (101) may perform operations described below with reference to FIGS. 4A to 19, and may control components included in the electronic device (101). For example, the processor (320) may correspond to a plurality of processors that collectively perform a plurality of operations by dividing the operations among the processors.

[0073] According to one embodiment, the processor (220) may be configured with one or more processors. For example, the processor (220) may include a main processor (e.g., an application processor (AP)) and a secondary processor (e.g., a neural processing unit (NPU), a graphics processing unit (GPU), a secure processor unit (SPU)). For example, the processor (220) may include a plurality of computational cores.

[0074] According to one embodiment, the processor (320) can identify the state and change of the state of the electronic device (101). For example, the processor (320) can identify a state in which the electronic device (101) is folded or unfolded through the hinge assembly. For example, the processor (320) can identify a first state, a second state, and a third state of the electronic device (101) by controlling the sensor (376). For example, the first state of the electronic device (101) may include a state in which the first display is folded by the first housing being rotated by the first hinge assembly, and a state in which the first display is folded by the third housing being rotated by the second hinge assembly. The first state may correspond to a folded state of the electronic device (101). For example, the second state of the electronic device (101) may include a state in which the first display is folded by the first hinge assembly and the first display is unfolded by the second hinge assembly. Alternatively, the second state of the electronic device (101) may include a state in which the first display is folded by the second hinge assembly and the first display is unfolded by the first hinge assembly. The second state may correspond to a state in which the electronic device (101) is half-folded. For example, the third state of the electronic device (101) may include a state in which the first display is unfolded by the first hinge assembly and the second hinge assembly. The third state may correspond to a state in which the electronic device (101) is unfolded. For example, the processor (320) may identify that the electronic device (101) has changed from the first state to the second state. For example, the processor (320) can identify that the electronic device (101) changes from a second state to a third state. For example, the processor (320) can identify that the electronic device (101) changes from a third state to a second state. For example, the processor (320) can identify that the electronic device (101) changes from a second state to a first state.

[0075] According to one embodiment, the processor (320) can control the display (360) to display content. The content can include at least one of text, still images, moving images, web pages, and application execution screens.

[0076] In one embodiment, the processor (320) may identify a portion of the display (360) on which content is to be displayed. For example, the processor (320) may identify a first portion on which content is to be displayed based on a change from a first state to a second state. For example, the processor (320) may identify a first portion on which content is to be displayed based on a change from a second state to a third state. For example, the processor (320) may re-identify the first portion in response to receiving a user input adjusting the first region.

[0077] According to one embodiment, the processor (320) can control the display (360) to provide first content through a first portion and to provide a black screen through a second portion. For example, the processor (320) can set a window view corresponding to the first portion and output the first content through the window view. For example, the processor (320) can control the voltage, current, and / or update cycle of light-emitting elements corresponding to the second portion, for which no window view is set, using a display driving circuit (e.g., 230 of FIG. 2), thereby providing a black screen.

[0078] In one embodiment, the processor (320) can control the display (360). For example, the processor (320) can control the light-emitting elements of the display (360). For example, the processor (320) can control the voltage and / or current provided to the light-emitting elements of the display (360). For example, the processor (320) can control the refresh cycle of the light-emitting elements of the display (360). For example, the processor (320) can control the first refresh cycle of the light-emitting elements corresponding to the first portion to be shorter than the second refresh cycle of the light-emitting elements corresponding to the second portion. For example, the processor (320) can control some portions of the display (360) to provide a black screen. For example, the processor (320) can control the display (360) to be deactivated.

[0079] According to one embodiment, the processor (320) may control the electronic device (101) to operate in a battery saving mode. For example, the processor (320) may control the electronic device (101) to operate in the battery saving mode in response to a voltage provided to the electronic device (101) by a battery (e.g., battery (189) of FIG. 1) being lower than a predetermined voltage. The processor (320) may control the electronic device (101) to operate in the battery saving mode based on a user input received through a user interface regarding the execution of the battery saving mode. The processor (320) may control the electronic device (101) to release the battery saving mode based on a user input received through a user interface regarding the release of the battery saving mode. For example, the processor (320) may identify that the electronic device is operating in the battery saving mode based on a setting value related to the battery saving mode.

[0080] According to one embodiment, the processor (320) may control the electronic device (101) to change the display providing content based on whether the electronic device (101) is operating in a battery saving mode. For example, the processor (320) may change the display providing content from a second display to a first display based on whether the electronic device (101) is operating in a battery saving mode.

[0081] In one embodiment, the processor (320) may identify an area where content is to be displayed. For example, the processor (320) may identify an area where content is to be displayed in response to a change in the state of the electronic device (101) from a first state to a second state. For example, the processor (320) may re-identify an area where content is to be displayed in response to a change in the state of the electronic device (101) from a second state to a third state. For example, the processor (320) may re-identify an area in response to a user input that adjusts an area where content is to be displayed.

[0082] FIGS. 4A to 4D are drawings for explaining an electronic device according to one embodiment.

[0083] FIG. 4a is a drawing for explaining one side of an unfolded electronic device (400), FIG. 4b is a drawing for explaining the opposite side of the electronic device (400) illustrated in FIG. 4a, FIG. 4c is a drawing for explaining both sides of the electronic device (400) in a folded state, and FIG. 4d is a drawing for explaining the bottom of the electronic device (400) in a folded state.

[0084] Referring to FIGS. 4A to 4D, the electronic device (400) may include a housing (410), a first display (420), a second display (430), a first hinge assembly (452), a second hinge assembly (451), and a camera (441, 442).

[0085] In one embodiment, the housing (410) may include a first housing (411), a second housing (412), and a third housing (413). The first housing (411) may be rotatably coupled to the second housing (412) by a first hinge assembly (452). The third housing (413) may be rotatably coupled to the second housing (412) by a second hinge assembly (451). For example, after the first housing (411) is rotated to approach the second housing (412) by the first hinge assembly (452), the third housing (413) may be rotated to approach the second housing (412) by the second hinge assembly (451). For example, after the third housing (413) is rotated away from the second housing (412) by the second hinge assembly (451), the first housing (411) can be rotated away from the second housing (412) by the first hinge assembly (452).

[0086] According to one embodiment, the first display (420) may be disposed within the housing (410). The first display (420) may be disposed across one side of the first housing (411), one side of the second housing (412), and one side of the third housing (413). For example, the first display (420) may be disposed on the front surfaces of the first housing (411), the second housing (412), and the third housing (413). For example, the first display (420) may have a first area (421) disposed within the first housing (411), a second area (422) disposed within the second housing (412), and a third area (423) disposed within the third housing (413).

[0087] In one embodiment, the first display (420) may be a flexible display. The first display (420) may be folded or unfolded by at least one of the first hinge assembly (452) and the second hinge assembly (451). For example, the first area (421) of the first display (420) may be folded toward the second area (422) of the first display (420) by rotating the first housing (411) so that it approaches the second housing (412) through the first hinge assembly (452). For example, the first housing (411) can be rotated away from the second housing (412) through the first hinge assembly (452), so that the first area (421) adjacent to the second area (422) of the first display (420) and the second area (422) of the first display (420) can be unfolded. For example, the third housing (413) can be rotated to approach the second housing (412) through the second hinge assembly (451), so that the third area (423) of the first display (420) can be folded toward the second area (422) of the first display (420). For example, the first display (420) may be rotated so that the third housing (413) is rotated away from the second housing (412) via the second hinge assembly (451), thereby unfolding the third area (423) of the first display (420) adjacent to the second area (422) of the first display (420).

[0088] According to one embodiment, the first display (420) can be in various states by being bent or unfolded by the first hinge assembly (452) and the second hinge assembly (451). For example, the first display (420) can be in a first state in which the first housing (411) is rotated by the first hinge assembly (452) to be adjacent to the second housing (412), so that the first region (421) is positioned adjacent to the second region (422), and the third housing (413) is rotated by the second hinge assembly (451) to be adjacent to the second housing (412), so that the third region (423) is positioned adjacent to the second region (422). The first state may correspond to a folded state of the first display (420). For example, the first display (420) may be positioned in a second state in which the first area (421) is positioned adjacent to the second area (422) by rotating the first housing (411) adjacent to the second housing (412) by the first hinge assembly (452), and the third housing (413) is positioned away from the second housing (412) by the second hinge assembly (451), so that the third area (423) and the second area (422) are unfolded. The second state may correspond to a half-folded state in which the first display (420) is folded. For example, the first display (420) may be in a third state in which the third region (423) and the second region (422) are unfolded by rotating the third housing (413) away from the second housing (412) by the second hinge assembly (451), and the first region (421) and the second region (422) are unfolded by rotating the first housing (411) away from the second housing (412) by the first hinge assembly (452). The third state may correspond to an unfolded state of the first display (420).

[0089] According to one embodiment, the first display (420) may include a color filter array (e.g., 740 of FIG. 7). The first display (420) may include the color filter array (e.g., 740 of FIG. 7) instead of a polarizing layer (e.g., 640 of FIG. 6). A first display (420) including a color filter array is described in detail below with reference to FIG. 7.

[0090] In one embodiment, the second display (430) may be disposed within the second housing (412). For example, the second display (430) may be disposed on the other side of the side where the first display (420) is disposed within the second housing (412). For example, the first display (420) may be disposed on the front side of the second housing (412), and the second display (430) may be disposed on the back side of the second housing (412). The second display (430) may include a polarizing layer (e.g., 640 of FIG. 6). The second display (430) including the polarizing layer will be described in detail below with reference to FIG. 6.

[0091] According to one embodiment, hinge assemblies (451, 452) may be positioned on both sides of the second housing (412). For example, a first hinge assembly (452) that couples the first housing (411) and the second housing (412) may be positioned on one side of the second housing (412), and a second hinge assembly (451) that couples the third housing (413) and the second housing (412) may be positioned on the other side of the second housing (412). The first housing (411) and the third housing (413) may be sequentially rotated by the first hinge assembly (452) and the second hinge assembly (451). For example, after the first housing (411) is rotated to approach the second housing (412) by the first hinge assembly (452), the third housing (413) can be rotated to approach the second housing (412) by the second hinge assembly (451). For example, after the third housing (413) is rotated away from the second housing (412) by the second hinge assembly (451), the first housing (411) can be rotated away from the second housing (412) by the first hinge assembly (452). The first hinge assembly (452) can be formed smaller than the second hinge assembly (451). For example, the first hinge assembly (452) can include a plate that is narrower than the plate of the second hinge assembly (451).

[0092] In one embodiment, the camera (441) may be disposed within the third housing (413). For example, the camera (441) may be disposed on the other side of the third housing (413) from the side where the first display (420) is disposed. For example, the first display (420) may be disposed on the front of the third housing (413), and the camera (441) may be disposed on the rear of the third housing (413). There may be a plurality of cameras (441). For example, the camera (441) may include, but is not limited to, a first camera having a wide-angle field of view, a second camera having a standard field of view, and a third camera having a telephoto field of view.

[0093] In one embodiment, the camera (442) may be positioned within the second housing (412). For example, the camera (442) may be positioned on the other side of the second housing (412) from the side where the first display (420) is positioned. For example, the first display (420) may be positioned on the front side of the second housing (412), and the camera (442) may be positioned on the rear side of the second housing (412). For example, the camera (442) may be positioned to overlap at least a portion of the second display (430).

[0094] In one embodiment, the button (460) may be positioned on the third housing (413). For example, the button (460) may be positioned on the opposite side of the third housing (413) to the side where the second hinge assembly (451) is coupled. By positioning the button (460) on the third housing (413), the hand pressing the button (460) is the same regardless of whether the electronic device is folded or unfolded, so that the operating method can be consistent. The button (460) can receive user input regarding a predetermined function to be performed by the electronic device (400).

[0095] FIGS. 5A to 5D are drawings for explaining an electronic device according to one embodiment.

[0096] FIG. 5a is a drawing for explaining one side of an unfolded electronic device (500), FIG. 5b is a drawing for explaining the opposite side of the electronic device (500) illustrated in FIG. 5a, FIG. 5c is a drawing for explaining both sides of the electronic device (500) in a folded state, and FIG. 5d is a drawing for explaining the bottom side of the electronic device (500) in a folded state.

[0097] Referring to FIGS. 5A to 5D, the electronic device (500) may include a housing (510), a first display (520), a second display (530), a first hinge assembly (551), a second hinge assembly (552), and a camera (541, 542).

[0098] In one embodiment, the housing (510) may include a first housing (511), a second housing (512), and a third housing (513). The first housing (511) may be rotatably coupled to the second housing (512) by a first hinge assembly (551). The third housing (513) may be rotatably coupled to the second housing (512) by a second hinge assembly (552). For example, after the third housing (513) is rotated to approach the second housing (512) by the second hinge assembly (552), the first housing (511) may be rotated to approach the second housing (512) by the first hinge assembly (551). For example, after the first housing (511) is rotated away from the second housing (512) by the first hinge assembly (551), the third housing (513) can be rotated away from the second housing (512) by the second hinge assembly (552).

[0099] According to one embodiment, the first display (520) may be disposed within the housing (510). The first display (520) may be disposed across one side of the first housing (511), one side of the second housing (512), and one side of the third housing (513). For example, the first display (520) may be disposed on the front surfaces of the first housing (511), the second housing (512), and the third housing (513). For example, the first display (520) may have a first area (521) disposed within the first housing (511), a second area (522) disposed within the second housing (512), and a third area (523) disposed within the third housing (513).

[0100] In one embodiment, the first display (520) may be a flexible display. The first display (520) may be folded or unfolded by at least one of the first hinge assembly (551) and the second hinge assembly (552). For example, the first display (520) may be folded such that the first region (521) is toward the second region (522) by rotating the first housing (511) toward the second housing (512) through the first hinge assembly (551). For example, the first display (520) may be unfolded such that the first region (521) adjacent to the second region (522) is unfolded such that the first housing (511) is rotated away from the second housing (512) through the first hinge assembly (551). For example, the first display (520) can be rotated so that the third housing (513) approaches the second housing (512) through the second hinge assembly (552), thereby allowing the third region (523) to fold toward the second region (522). For example, the first display (520) can be rotated so that the third housing (513) moves away from the second housing (512) through the second hinge assembly (552), thereby allowing the third region (523) adjacent to the second region (522) and the second region (522) to unfold.

[0101] According to one embodiment, the first display (520) can be in various states by being bent or unfolded by the first hinge assembly (551) and the second hinge assembly (552). For example, the first display (520) can be in a first state in which the third area (523) is positioned adjacent to the second area (522) by rotating the third housing (513) adjacent to the second housing (512) by the second hinge assembly (552), and the first area (521) is positioned adjacent to the second area (522) by rotating the first housing (511) adjacent to the second housing (512) by the first hinge assembly (551). The first state may correspond to a folded state of the first display (520). For example, the first display (520) may be rotated by the second hinge assembly (552) so that the third housing (513) is adjacent to the second housing (512), so that the third region (523) is positioned adjacent to the second region (522), and the first housing (511) may be rotated by the first hinge assembly (551) so that the first region (521) and the second region (522) are unfolded. The second state may correspond to a half-folded state of the first display (520). For example, the first display (520) may be in a third state in which the first region (521) and the second region (522) are unfolded by rotating the first housing (511) away from the second housing (512) by the first hinge assembly (551), and the third region (523) and the second region (522) are unfolded by rotating the third housing (513) away from the second housing (512) by the second hinge assembly (552).

By the first hinge assembly (551) and the second hinge assembly (552), the first housing (511) and the third housing (513) may be sequentially rotated. For example, after the third housing (513) is rotated to approach the second housing (512) by the second hinge assembly (552), the first housing (511) can be rotated to approach the second housing (512) by the first hinge assembly (551).

[0108] FIG. 6 is a diagram illustrating a display of an electronic device according to one embodiment. The display (600) may be the second display (430) of the electronic device (400) described above with reference to FIGS. 4A to 4D . The display (600) may be the second display (530) of the electronic device (500) described above with reference to FIGS. 5A to 5D .

[0109] According to one embodiment, the display (600) may include a substrate (610), a light-emitting layer (620), a touch sensor layer (630), and a polarizing layer (640).

[0110] According to one embodiment, the substrate (610) may include circuitry that controls light-emitting elements included in the light-emitting layer (620). For example, the substrate (610) may include circuitry that includes a gate, a source, a drain, and electrodes that control the light-emitting elements.

[0111] According to one embodiment, the light-emitting layer (620) may include light-emitting elements (621, 622, 623). For example, the light-emitting layer (620) may include a light-emitting element (621) that emits red light, a light-emitting element (622) that emits green light, and a light-emitting element (623) that emits blue light. A black matrix (624) may be positioned between the light-emitting elements (621, 622, 623). Each of the light-emitting elements (621, 622, 623) may be created using a material (e.g., an organic material) corresponding to the color of light emitted.

[0112] According to one embodiment, the touch sensor layer (630) can detect a touch input of a user using an electronic device (e.g., 400, 500) including a display (600). The touch sensor layer (630) can be formed by being deposited on the light-emitting layer (620).

[0113] In one embodiment, the polarizing layer (640) can improve the visibility of the display (600). For example, the polarizing layer (640) can improve the visibility of the display (600) by blocking external light reflection from the display (600). The polarizing layer (640) can prevent a decrease in visibility caused by external light entering the display (600) and being reflected on the electrodes of the display (600).

[0114] FIG. 7 is a diagram illustrating a display of an electronic device according to one embodiment. The display (700) may be the first display (420) of the electronic device (400) described above with reference to FIGS. 4A to 4D . The display (700) may be the first display (520) of the electronic device (500) described above with reference to FIGS. 5A to 5D .

[0115] According to one embodiment, the display (700) may include a substrate (710), a light-emitting layer (720), a touch sensor layer (730), and a color filter layer (740). The display (700) may include the color filter layer (740) instead of the polarizing layer (640).

[0116] According to one embodiment, the substrate (710) may include circuitry that controls light-emitting elements included in the light-emitting layer (720). For example, the substrate (710) may include circuitry that includes a gate, a source, a drain, and electrodes that control the light-emitting elements.

[0117] According to one embodiment, the light-emitting layer (720) may include light-emitting elements (721, 722, 723). For example, the light-emitting layer (720) may include a light-emitting element (721) that emits red light, a light-emitting element (722) that emits green light, and a light-emitting element (723) that emits blue light. A black matrix (724) may be positioned between the light-emitting elements (721, 722, 723). Each of the light-emitting elements (721, 722, 723) may be created using a material (e.g., an organic material) corresponding to the color it emits. The black matrix (724) may be black.

[0118] According to one embodiment, the touch sensor layer (730) can detect a touch input of a user using an electronic device (e.g., 400, 500) including a display (700). The touch sensor layer (730) can be formed by being deposited on the light-emitting layer (720).

[0119] According to one embodiment, the color filter layer (740) may include color channels (741, 742, 743) and a partition (744) positioned between the color channels (741, 742, 743). Each of the color channels (741, 742, 743) may include a filter that passes light of a color corresponding to the color of the corresponding light-emitting elements (721, 722, 723). For example, a first color channel (741) may include a filter that passes light of a color (red) corresponding to the color (red) of the corresponding light-emitting element (721). For example, a second color channel (742) may include a filter that passes light of a color (green) corresponding to the color (green) of the corresponding light-emitting element (722). For example, the third color channel (743) may include a filter that passes light of a color (blue) corresponding to the color (blue) of the corresponding light-emitting element (723). Light emitted from the light-emitting elements (721, 722, 723) passes through the color filter layer (740), thereby allowing the user to view a screen with improved visibility.

[0120] According to one embodiment, the color filter layer (740) can improve the visibility of the display (700). For example, the partition wall (744) of the color filter layer (740) can improve the visibility of the display (700) by blocking external light of the display (700) that is introduced into the interior of the display (700) and reflected on the electrodes of the display (700). For example, the color channels (741, 742, 743) of the color filter layer (740) can improve the visibility of the display (700) by passing light corresponding to a color corresponding to each of the color channels (741, 742, 743) among the external light of the display (700) reflected on the electrodes of the display (700). For example, the first color channel (741) can pass light corresponding to the color of red from the light reflected on the electrodes. The second color channel (742) can pass light corresponding to the color green from the light reflected on the electrode. The third color channel (743) can pass light corresponding to the color blue from the light reflected on the electrode. The light passing through the color channels (741, 742, 743) has the same color as the light generated from the corresponding light-emitting elements (721, 722, 723), respectively. Therefore, the external light reflected on the electrode of the display (700) can pass through the color channels (741, 742, 743), and thus has the same color as the light generated from the light-emitting elements (721, 722, 723), thereby improving the user's visibility.

[0121] According to one embodiment, when comparing the display (700) of FIG. 7 with the display (600) of FIG. 6, the display (700) of FIG. 7 may have the polarization layer (640) of the display (600) of FIG. 6 replaced with a color filter layer (740). By replacing the polarization layer (640) with the color filter layer (740), the display (700) of FIG. 7 may have a reduced thickness compared to the display (600) of FIG. 6. By replacing the polarization layer (640) with the color filter layer (740), the display (700) of FIG. 7 may have reduced power consumption compared to the display (600) of FIG. 6. The polarization layer (640) absorbs and / or blocks some of the light generated from the light-emitting layer (620), thereby lowering the light-emitting efficiency of the display (600). The display (700) including the color filter layer (740) does not absorb and / or block light generated from the light emitting layer (720), and thus its light emission efficiency is relatively not reduced compared to the display (600) including the polarizing layer (640). The display (700) including the color filter layer (740) can have a light transmittance increased by about 33% compared to the display (600) including the polarizing layer (640). Therefore, the display (700) of FIG. 7 can reduce power consumption by about 10% to about 30% to secure the same amount of light when outputting the same content as the display (600) of FIG. 6.

[0122] FIG. 8 is a diagram for explaining a display driving circuit of an electronic device according to one embodiment. Referring to FIG. 8, the electronic device (800) may include a display driving circuit (870) that controls a display. The display driving circuit (870) may correspond to the display driver IC (230) of FIG. 2. For example, the display driving circuit (870) may control light-emitting elements included in a first display (820) and / or light-emitting elements included in a second display (e.g., 430, 530). The display driving circuit (870) may be disposed between the first display (820) and the housing (810). For example, the display driving circuit (870) may be disposed between a first region (821) and a first housing (811). For example, the display driving circuit (870) may be disposed between a second region (822) and a second housing (812). For example, the display driving circuit (870) may be placed between the third region (823) and the third housing (813).

[0123] According to one embodiment, the display driving circuit (870) can control the voltage and / or current provided to the light-emitting elements of the display (820, 430 of FIG. 4B, 530 of FIG. 5B). For example, the display driving circuit (870) can control the voltage and / or current provided to each of the light-emitting elements of the display (820, 430 of FIG. 4B, 530 of FIG. 5B) to correspond to image information acquired from the processor. For example, the display driving circuit (870) can control the voltage and / or current based on the arrangement and / or size of the light-emitting elements. For example, the display driving circuit (870) can provide a predetermined constant voltage to the light-emitting elements of the display (820, 430 of FIG. 4B, 530 of FIG. 5B). For example, the display driving circuit (870) can provide a current corresponding to the brightness value of the light-emitting elements of the display (820, 430 of FIG. 4B, 530 of FIG. 5B). For example, the display driving circuit (870) can provide a current of 0 A (ampere) corresponding to the brightness value of the light-emitting elements of the display (820, 430 of FIG. 4B, 530 of FIG. 5B) being 0.

[0124] According to one embodiment, the display driving circuit (870) can activate or deactivate the display (820, 430 of FIG. 4b, 530 of FIG. 5b).

[0125] For example, the display driving circuit (870) can disable the display (820, 430 of FIG. 4B, 530 of FIG. 5B) by applying a voltage and / or current to the display (820, 430 of FIG. 4B, 530 of FIG. 5B) below a predetermined value. For example, the display driving circuit (870) can disable the display (820, 430 of FIG. 4B, 530 of FIG. 5B) by applying a voltage below a driving voltage of the display (820, 430 of FIG. 4B, 530 of FIG. 5B).

[0126] For example, the display driving circuit (870) can activate the display (820, 430 of FIG. 4B, 530 of FIG. 5B) by providing a voltage and / or current of a predetermined value or higher to the display (820, 430 of FIG. 4B, 530 of FIG. 5B). For example, the display driving circuit (870) can activate the display (820, 430 of FIG. 4B, 530 of FIG. 5B) by applying a voltage higher than a driving voltage of the display (820, 430 of FIG. 4B, 530 of FIG. 5B).

[0127] For example, the display driving circuit (870) can deactivate the display (820, 430 of FIG. 4B, 530 of FIG. 5B) by not providing current to the display (820, 430 of FIG. 4B, 530 of FIG. 5B). For example, the display driving circuit (870) can activate the display (820, 430 of FIG. 4B, 530 of FIG. 5B) by providing current to the display (820, 430 of FIG. 4B, 530 of FIG. 5B).

[0128] According to one embodiment, the display driving circuit (870) can control the update cycle of the light-emitting elements of the display (820, 430 of FIG. 4B, 530 of FIG. 5B). For example, the display driving circuit (870) can control the update cycle of the current values ​​of the light-emitting elements. For example, the display driving circuit (870) can control the update cycle of the light-emitting elements to about 1 / 60 second.

[0129] According to one embodiment, the display driving circuit (870) can control the update cycle of each of the light-emitting elements of the display (820, 430 of FIG. 4B, 530 of FIG. 5B). The display driving circuit (870) can control the update cycle of each of the light-emitting elements differently. For example, the display driving circuit (870) can control the update cycle of the first region (821) as a first cycle, control the update cycle of the second region (822) as a second cycle, and control the update cycle of the third region (823) as a third cycle. In this case, the first cycle, the second cycle, and the third cycle may be the same cycle or different cycles. For example, the display driving circuit (870) can update the light-emitting elements corresponding to the first portion every first cycle, and update the light-emitting elements corresponding to the second portion every second cycle. The first portion and the second portion may be set by an operating system (OS) and / or an application that drives the electronic device (800).

[0130] According to one embodiment, the display driving circuit (870) can control the update cycle of the light emitting elements based on the property of the image data. For example, the display driving circuit (870) can control the update cycle of the light emitting elements to about 1 / 10 second based on the property of the image data called text. For example, the display driving circuit (870) can control the update cycle of the light emitting elements to about 1 / 60 second based on the property of the image data called video. For example, the display driving circuit (870) can control the update cycle of the light emitting elements to about 1 / 120 second based on the property of the image data called game. For example, the display driving circuit (870) can control the update cycle of the light emitting elements to about 1 / 20 second based on the property of the image data called still image. For example, the display driving circuit (870) can control the update cycle of the light emitting elements to about 1 second based on the property of the image data called blank or black screen. For example, the display driving circuit (870) can control the refresh cycle of the light emitting elements based on the properties of the type of application being executed. For example, the display driving circuit (870) can control the refresh cycle of the light emitting elements to approximately 1 / 30 second based on the properties of the image data called a navigation application. For example, the display driving circuit (870) can control the refresh cycle of the light emitting elements to approximately 1 / 120 second based on the properties of the image data called a web browsing application.

[0131] The display driving circuit included in the electronic device described with reference to FIGS. 4A to 4D and / or the display driving circuit included in the electronic device described with reference to FIGS. 5A to 5D may be analogically applied to the display driving circuit (870) described with reference to FIG. 8.

[0138] According to one embodiment, the display driving circuits (971, 972, 973) can activate or deactivate the display (920, 430 of FIG. 4B, 530 of FIG. 5B). For example, the first display driving circuit (971) can deactivate the first region (921) by applying a voltage lower than a driving voltage of the first region (921) to the first region (921). For example, the first display driving circuit (971) can activate the first region (921) by applying a voltage higher than a driving voltage of the first region (921) to the first region (921).

[0139] The display driving circuit included in the electronic device described with reference to FIGS. 4A to 4D and / or the display driving circuit included in the electronic device described with reference to FIGS. 5A to 5D may be analogously applied to the display driving circuit (971, 972, 973) described with reference to FIG. 9.

[0140] FIG. 10 is a drawing for explaining an operating method of an electronic device according to one embodiment.

[0141] Referring to FIG. 10, the electronic device (1000) can be in various states by the hinge assemblies. For example, the states of the electronic device (1000) can include a first state, a second state, and a third state.

[0142] For example, a first state (1000a) of the electronic device (1000) may include a state in which the first housing (1011) is rotated adjacent to the second housing (1012) by the first hinge assembly (1051), so that the first region is positioned adjacent to the second region, and the third housing (1013) is rotated adjacent to the second housing (1012) by the second hinge assembly (not shown), so that the third region (1023) is positioned adjacent to the second region. The first state (1000a) may correspond to a folded state of the electronic device (1000).

[0143] For example, the second state (1000b) of the electronic device (1000) may include a state in which the first housing (1011) is rotated adjacent to the second housing (1012) by the first hinge assembly (1051), so that the first region is positioned adjacent to the second region, and the third housing (1013) is rotated away from the second housing (1012) by the second hinge assembly (not shown), so that the third region (1023) and the second region are unfolded. The second state (1000b) may correspond to a half-folded state of the electronic device (1000).

[0144] For example, a third state (not shown) of the electronic device (1000) may include a state in which the third housing (1013) is rotated away from the second housing (1012) by the second hinge assembly (not shown), thereby unfolding the third region (1023) and the second region, and a state in which the first region and the second region are unfolded by rotating the first housing (1011) away from the second housing (1012) by the first hinge assembly (1051). The third state (not shown) may correspond to an unfolded state of the electronic device (1000).

[0145] According to one embodiment, the electronic device (1000) can detect the angle between the first housing (1011) and the second housing (1012), and the angle between the second housing (1012) and the third housing (1013) using a sensor (not shown). For example, the electronic device (1000) can detect the angle between the first housing (1011) and the second housing (1012), and the angle between the second housing (1012) and the third housing (1013) by detecting an electrical change (e.g., a change in voltage) caused by the distance between the first housing (1011) and the second housing (1012) and the distance between the second housing (1012) and the third housing (1013) getting closer or farther away using a hall sensor and a magnetic material. For example, the electronic device (1000) can detect the angle between the first housing (1011) and the second housing (1012) and the angle between the second housing (1012) and the third housing (1013) by detecting a change in an infrared signal generated by the distance between the first housing (1011) and the second housing (1012) and the distance between the second housing (1012) and the third housing (1013) getting closer or farther away using an infrared sensor. For example, the electronic device (1000) can detect an angle between the first housing (1011) and the second housing (1012) and an angle between the second housing (1012) and the third housing (1013) by detecting a change in electromagnetic force caused by a distance between the first housing (1011) and the second housing (1012) and the distance between the second housing (1012) and the third housing (1013) becoming closer or farther apart using an electromagnetic sensor.

[0146] According to one embodiment, the electronic device (1000) can identify a change in the state of the electronic device (1000) based on the detected angle. For example, the electronic device (1000) can identify that the state of the electronic device (1000) has changed to a first state (1000a), a second state (1000b), and a third state (not shown). For example, the electronic device (1000) can identify that the electronic device (1000) has changed from the first state (1000a) to the second state (1000b) based on identifying that the angle between the third housing (1013) and the second housing (1012) is greater than or equal to a predetermined angle. For example, the electronic device (1000) can identify that the electronic device (1000) has changed from the second state (1000b) to the third state (not shown) based on identifying that the angle between the third housing (1013) and the second housing (1012) is greater than or equal to a predetermined angle and that the angle between the first housing (1011) and the second housing (1012) is greater than or equal to a predetermined angle. For example, the electronic device (1000) can identify that the electronic device (1000) has changed from the third state (not shown) to the second state (1000b) based on identifying that the angle between the third housing (1013) and the second housing (1012) is greater than or equal to a predetermined angle and that the angle between the first housing (1011) and the second housing (1012) is less than or equal to a predetermined angle. For example, the electronic device (1000) can identify that the electronic device (1000) has changed from the second state (1000b) to the first state (1000a) based on identifying that the angle between the third housing (1013) and the second housing (1012) is less than a predetermined angle and that the angle between the first housing (1011) and the second housing (1012) is less than a predetermined angle.

[0147] According to one embodiment, when the electronic device (1000) is in the first state (1000a), it can display first content through the second display (1030). For example, the electronic device (1000) can display first content including at least one of text, a still image, a video, a web page, and an application execution screen through the second display (1030).

[0148] According to one embodiment, the electronic device (1000) may change the display providing the first content from the second display (1030) to the first display (1020) in response to a change in the state of the electronic device (1000) from the first state (1000a) to the second state (1000b). For example, the electronic device (1000) may display the first content through the first display (1020) and deactivate the second display (1030). For example, the electronic device (1000) may deactivate the second display (1030) by controlling a voltage and / or current provided to the second display (1030) using a display driving circuit (e.g., 870 of FIG. 8).

[0149] According to one embodiment, the electronic device (1000) can display first content in at least one area among a first area (not shown), a second area (not shown), or a third area (1023) of the first display. The electronic device (1000) can identify a portion of the first display (1020) on which the first content is to be displayed. For example, the electronic device (1000) can identify the third area (1023) of the first display as the first portion on which the first content is to be displayed. For example, the electronic device (1000) can identify a portion of the first display (1020) that includes a ratio corresponding to a ratio of the second display (1030) as the first portion on which the first content is to be displayed. For example, the electronic device (1000) can identify a portion of the first display (1020) that includes a resolution corresponding to a resolution of the first content as the first portion on which the first content is to be displayed.

[0150] According to one embodiment, the electronic device (1000) can display first content within a portion of the identified first display (1020). For example, the electronic device (1000) can set a window view to correspond to the portion of the identified first display (1020) and output the first content through the window view.

[0151] According to one embodiment, the electronic device (1000) can provide a black screen through a second portion of the first display (1020), which is the remainder of the first portion where the first content is to be displayed. For example, the electronic device (1000) can provide a black screen by controlling the voltage and / or current of light-emitting elements corresponding to the second portion using a display driving circuit (e.g., 870 of FIG. 8). For example, the electronic device (1000) can provide a black screen by controlling the update cycle of the light-emitting elements corresponding to the second portion. For example, the electronic device (1000) can control the update cycle of the light-emitting elements corresponding to the second portion to be longer than the update cycle of the light-emitting elements corresponding to the first portion.

[0152] FIG. 11 is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0153] Referring to FIG. 11, the electronic device (1100) may operate in a battery saving mode (power saving mode). The battery saving mode may include an operation mode of the electronic device (1100) to minimize battery usage of the electronic device (1100) and increase usable time. For example, the battery saving mode may include an operation mode in which the electronic device (1100) performs at least one operation from among an operation of adjusting screen brightness, an operation of limiting the computational performance of the processor, an operation of limiting wireless connection, an operation of disabling a location sensor, an operation of terminating a background processor, an operation of limiting the refresh rate of the display, an operation of reducing the resolution of the display, an operation of limiting screen effects, an operation of limiting data synchronization, and an operation of limiting software updates. For example, the electronic device (1100) may operate in the battery saving mode in response to a voltage provided to the electronic device (1100) by a battery mounted in the electronic device (1100) being below a predetermined voltage. For example, the electronic device (1100) may operate in battery saving mode based on a user input received through a user interface regarding the execution of the battery saving mode. For example, the electronic device (1100) may operate in battery saving mode based on a user input touching an object related to the execution of the battery saving mode.

[0154] According to one embodiment, the electronic device (1100) can identify that the state of the electronic device has changed from a first state (1100a) to a second state (1100b). For example, the electronic device (1100) can be in a first state (1100a) in which the first housing (1111) is rotated adjacent to the second housing (1112) by the first hinge assembly (1151), such that the first region is positioned adjacent to the second region, and the third housing (1113) is rotated adjacent to the second housing (1112) by the second hinge assembly (not shown), such that the third region (1123) is positioned adjacent to the second region. The electronic device (1100) can be positioned in a second state (1100b) in which the third state (1123) and the second state are unfolded by rotating the first housing (1111) adjacent to the second housing (1112) by the first hinge assembly (1151) so that the first display (1120) is positioned adjacent to the second state, and the third housing (1113) is rotated away from the second housing (1112) by the second hinge assembly (not shown). For example, the electronic device (1100) can identify that the state of the electronic device (1100) is changed from the first state (1100a) to the second state (1100b) by identifying that the third housing (1113) is rotated away from the second housing (1112) by a sensor (not shown).

[0155] According to one embodiment, the electronic device (1100) may operate in a battery saving mode based on a change in the state of the electronic device (1100) from a first state (1100a) to a second state (1100b). For example, the electronic device (1100) may operate in a battery saving mode in response to a rotation of the third housing (1113) away from the second housing (1112). For example, the electronic device (1100) may identify a change in the state of the electronic device (1100) from the first state (1100a) to the second state (1100b) as a trigger for the electronic device (1100) to operate in the battery saving mode.

[0156] According to one embodiment, the electronic device (1100) may provide a user interface regarding execution of a battery saving mode based on a change in the state of the electronic device from a first state (1100a) to a second state (1100b). For example, the electronic device (1100) may provide a user interface on a third portion (1123) of the first display (1120) of the electronic device (1100) and / or a second display (1130). For example, the electronic device (1100) may provide a user interface for selecting whether to execute the battery saving mode. For example, the electronic device (1100) may display an object (e.g., an icon, a menu) that executes the battery saving mode. For example, the electronic device (1100) may provide a user interface regarding execution of the battery saving mode when the voltage provided to the electronic device (1100) by the battery mounted in the electronic device (1100) is below a predetermined voltage.

[0157] According to one embodiment, the electronic device (1100) may change the display providing the first content from the second display (1130) to the first display (1120) based on the operation in the battery saving mode. For example, the electronic device (1100) may deactivate the second display (1130) and display the first content within the first portion of the first display (1120) based on the state of the electronic device (1100) changing from the first state (1100a) to the second state (1100b) while operating in the battery saving mode. For example, the electronic device (1100) may provide a user interface related to the execution of a battery saving mode within a first portion of the first display (1120) based on a change in the state of the electronic device (1100) from a first state (1100a) to a second state (1100b), and may provide first content through the first display (1120) in response to a user input obtained through the user interface. For example, the first portion of the first display (1120) may correspond to a third area (1123).

[0158] FIG. 12 is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0159] According to one embodiment, the electronic device (1200) can identify that the state of the electronic device (1200) has changed from a first state (1200a) to a second state (1200b). For example, the electronic device (1200) can be in a first state (1200a) in which the first housing (1211) is rotated adjacent to the second housing (1212) by the first hinge assembly (1251), such that the first region (1221) is positioned adjacent to the second region (1222), and the third housing (1213) is rotated adjacent to the second housing (1212) by the second hinge assembly (not shown), such that the third region (1223) is positioned adjacent to the second region (1222). The electronic device (1200) can be in a second state (1200b) in which the first display (1220) is positioned adjacent to the second state (1222) by rotating the first housing (1211) by the first hinge assembly (1251) so that the first area (1221) is positioned adjacent to the second area (1222), and the third housing (1213) is rotated away from the second housing (1212) by the second hinge assembly (not shown), so that the third area (1223) and the second area (1222) are unfolded. For example, the electronic device (1200) can identify that the state of the electronic device (1200) is changed from the first state to the second state (1200b) by identifying that the third housing (1213) is rotated away from the second housing (1212) through a sensor (not shown). For example, the electronic device (1200) can identify that the electronic device (1200) has changed from the first state (1200a) to the second state (1200b) based on identifying that the angle between the third housing (1213) and the second housing (1212) is greater than or equal to a predetermined angle.

[0160] According to one embodiment, the electronic device (1200) can change the display providing the first content in response to a change in the state of the electronic device (1200) from the first state (1200a) to the second state (1200b). For example, the electronic device (1200) can provide the first content being provided through the second display (1230) through the first display (1220) by identifying that the third housing (1213) is rotated away from the second housing (1212). For example, the electronic device (1200) can deactivate the second display (1230) and display the first content within the first portion of the first display (1220).

The electronic device (1200) can be in the third state (1200c) in which the third region (1223) and the second region (1222) are unfolded by rotating the third housing (1213) away from the second housing (1212) by the second hinge assembly (not shown), and the first region (1221) and the second region (1222) are unfolded by rotating the first housing (1211) away from the second housing (1212) by the first hinge assembly (1251). For example, the electronic device (1200) can identify that the state of the electronic device (1200) has changed from the second state (1200b) to the third state (1200c) based on identifying that the angle between the third housing (1213) and the second housing (1212) is greater than or equal to a predetermined angle and that the angle between the first housing (1211) and the second housing (1212) is greater than or equal to a predetermined angle.

[0162] According to one embodiment, the electronic device (1200) may re-identify and / or update the portion on which the first content is output in response to a change in the state of the electronic device (1200) from the second state (1200b) to the third state (1200c). For example, the electronic device (1200) may identify a portion of the first display (1220) that includes a ratio corresponding to the ratio of the first content as the first portion to display the first content. For example, the electronic device (1200) may identify a portion of the first display (1220) that includes a resolution corresponding to the resolution of the first content as the first portion to display the first content. For example, the portion of the first display (1220) that displays the first content may be preset. For example, the electronic device (1200) can identify the first area (1221) and the second area (1222) of the first display (1220) as the first portion to display the first content. For example, the electronic device (1200) can update the portion to display the first content by setting the portion to display the re-identified first content as the first portion.

[0190] Referring to operation 1620, the electronic device may provide first content through the first portion, and provide a black screen through the second portion of the first display, which is the remaining portion except the first portion. For example, the electronic device may set a window view corresponding to the first portion, and output the first content through the window view. For example, the electronic device may provide a black screen by controlling the voltage, current, and / or update cycle of light-emitting elements corresponding to the second portion, for which no window view is set, using a display driving circuit. For example, the electronic device may provide a black screen by not applying current to the light-emitting elements corresponding to the second portion. Operation 1620 may be analogically applied to the operations of the electronic device described with reference to FIG. 10.

[0191] Referring to operation 1630, the electronic device may disable the second display.

[0197] If the electronic device is operating in power saving mode, the electronic device can perform operation 1730. If the electronic device is not operating in power saving mode, the electronic device can perform operation 1720.

[0198] Referring to operation 1720, the electronic device may activate a power-saving mode of the electronic device. For example, the electronic device may activate the power-saving mode based on determining that the voltage provided to the electronic device by the battery mounted on the electronic device is below a predetermined voltage. For example, the electronic device may activate the power-saving mode based on user input received through a user interface regarding the execution of the power-saving mode.

[0199] For example, an electronic device may activate a power-saving mode based on a user input that touches an object associated with the power-saving mode. For example, the electronic device may activate a power-saving mode based on identifying that the state of the electronic device has changed from a first state to a second state.

[0200] Action 1720 may be analogized to the action of the electronic device described with reference to FIG. 10.

[0201] Referring to operation 1730, the electronic device can change the display providing the first content from the second display to the first display.
