[0021] FIG. 9 is a block diagram of an electronic device within a network environment according to various embodiments.

[0022] FIG. 10 is a block diagram of a display module according to various embodiments.

[0023] An electronic device may be a portable device, such as a smartphone, tablet, or laptop. The electronic device may include a display panel to visually present information and / or data. For example, a wider display panel may improve the visibility of information, but may decrease the portability of the electronic device. For example, the display panel may be deformable to address the trade-off between visibility and portability. As a non-limiting example, the display panel may be foldable one or more times. As a non-limiting example, the display panel may be at least partially rollable. As a non-limiting example, the display panel may be stretchable. The display panel may sometimes be referred to as a flexible display panel.

[0024] For example, the display panel may be incorporated into electronic devices having various form factors, as exemplified in the descriptions of FIGS. 1A to 1C.

[0025] Figures 1a to 1c illustrate examples of electronic devices having a display panel.

[0026] Referring to FIG. 1A, the electronic device may be a foldable electronic device (101) having a display panel (110). For the foldable electronic device (101), the display panel (110) may be foldable. For example, the display panel (110) may be folded more than once.

[0027] For example, when the display panel (110) is foldable once, the display panel (110) may include a first flat part (111), a second flat part (112) having a front surface facing the front surface of the first flat part (111) in a folded state of the foldable electronic device (101), and a folding part (113) positioned between the first flat part (111) and the second flat part (112) so as to bend between the unfolded state of the foldable electronic device (101) and the folded state.

[0028] For example, when the display panel (110) is foldable twice, the display panel (110) may further include a third planar part (114) having a front surface facing the front surface of the first planar part (111) or facing the rear surface of the second planar part (112) in the folded state, and a folding part (115) positioned between the first planar part (111) and the third planar part (114) so ​​as to be bent between the unfolded state and the folded state. However, the present invention is not limited thereto. For example, a two-foldable display panel (110), unlike the illustration in FIG. 1A, may include a third planar part (114) facing the front side of the second planar part (112) or the rear side of the first planar part (111) in the folded state, and a folding part (115) positioned between the first planar part (111) and the third planar part (114) so ​​as to be bent between the unfolded state and the folded state.

[0029] For example, the display panel (110) may be configured to fold based on a user input. For example, the user input may be caused by a force applied to the foldable electronic device (101) to fold the display panel (110). The force may be caused from outside the foldable electronic device (101) or from inside the foldable electronic device (101). For example, the user input may be received by the foldable electronic device (101) to change the size of an area of ​​the display panel (110) used for displaying information. For example, the user input may be received by the foldable electronic device (101) to execute a function that is supportable through the foldable electronic device (101). For example, the user input may include an input intended by the user for executing the function. However, the present invention is not limited thereto. For example, the user input may further include input that is caused by the user but is not intended by the user.

[0030] Referring to FIG. 1B, the electronic device may be a rollable electronic device (102) (or slideable electronic device (102)) having a display panel (110). For the rollable electronic device (102), the display panel (110) may be at least partially rollable. For example, at least a portion of the display panel (110) may be rollable.

[0031] For example, the display panel (110) can be rolled at least partially into the housing of the rollable electronic device (102) to change the size of the area (123) visible from the front surface of the rollable electronic device (102).

[0032] For example, when the display panel (110) is partially rolled, the display panel (110) may include a part (124) that can be rolled into the housing. For example, a front surface of the part (124) may be positioned outside (e.g., externally) of the housing for a first state (121) and within (e.g., internally) the housing for a second state (122). For example, since the front surface of the part (124) is positioned outside the housing for the first state (121) and within the housing for the second state (121), the size of the area (123) within the first state (121) may be larger than the size of the area (123) within the second state (122).

[0033] For example, the display panel (110) may be configured to roll based on a user input. For example, the user input may be caused by a force applied to the rollable electronic device (102) to at least partially roll the display panel (110). The force may be caused from outside the rollable electronic device (102) or from inside the foldable electronic device (102). For example, the user input may be received by the rollable electronic device (102) to change the size of an area of ​​the display panel (110) used for displaying information. For example, the user input may be received by the rollable electronic device (102) to execute a function that is supportable through the rollable electronic device (102). For example, the user input may include an input intended by a user for the execution of the function, but is not limited thereto. For example, the user input may further include input that is not intended by the user.

[0034] Referring to FIG. 1C, the electronic device may be a stretchable electronic device (103) having a display panel (110). For the stretchable electronic device (103), the display panel (110) may be at least partially stretchable.

[0035] For example, the display panel (110) may be at least partially stretched, as indicated by arrows (125), to change the size of the viewable area from the front face of the stretchable electronic device (103). As a non-limiting example, the display panel (110) may be more freely (or randomly) deformable than the display panel (110) illustrated in the descriptions of FIGS. 1A and 1B.

[0036] For example, the display panel (110) may be configured to stretch based on a user input. For example, the user input may be caused by a force applied to the stretchable electronic device (103) to at least partially stretch the display panel (110). The force may be caused from outside the stretchable electronic device (103) or from inside the stretchable electronic device (103). For example, the user input may be received by the stretchable electronic device (103) to change the size of an area of ​​the display panel (110) used for displaying information. For example, the user input may be received by the stretchable electronic device (103) to execute a function that is supportable through the stretchable electronic device (103). For example, the user input may include an input intended by the user for the execution of the function, but is not limited thereto. For example, the user input may further include an input that is not intended by the user.

[0037] The display panel (110) illustrated in the descriptions of FIGS. 1A to 1C may be configured to be at least partially deformable based on a user input. For example, the user input may cause a change in the size and / or shape of an area of ​​the display panel (110) that is visible from the front surface of the electronic device (e.g., a foldable electronic device (101), a rollable electronic device (102), or a stretchable electronic device (103)). As a non-limiting example, the user input may cause a function to be executed. As a non-limiting example, since the function may be executed differently depending on the change in the size and / or shape, a means or configuration for sensing a state of the display panel (110) according to the user input may be included in the electronic device (or the display panel (110)). For example, the display panel (110) may include conductive materials to sense, detect, or identify the state of the display panel (110) according to the user input. For example, the conductive material may be embedded within the display panel (110). The conductive material may often be referred to as a sensor, a sensing element, a sensing circuit, a strain sensor, or a strain gauge sensor.

[0038] For example, the electronic device may, in response to the user input, acquire data using the conductive material and execute the function based on the data. The electronic device may include components for acquiring the data and executing the function based on the data. The components are exemplified in the description of FIG. 1D.

[0039] FIG. 1d is a simplified block diagram of an exemplary electronic device.

[0040] Referring to FIG. 1D , the electronic device may be one of various electronic devices having various form factors, such as a foldable electronic device (101), a rollable electronic device (102), or a stretchable electronic device (103). For example, the electronic device may be one of various forms of mobile devices, such as a laptop, a smartphone, a cellular phone, a wearable device, a cellular phone, and other similar computing devices. The components, their relationships, and their functions depicted in FIG. 1D are exemplary only and do not limit the implementations described or claimed in this document. The electronic device may sometimes be referred to as a user device, a multifunction device, or a portable or handheld device.

[0041] The electronic device may include at least a part of the electronic device (901) of FIG. 9 or correspond to at least a part of the electronic device (901) of FIG. 9.

[0042] The electronic device may include a display (130) and a processor (131).

[0043] The display (130) may include at least a portion of the display module (960) of FIGS. 9 and 10 or correspond to at least a portion of the display module (960) of FIGS. 9 and 10. The display (130) may include a display panel (110) and a display driving circuit (132).

[0044] The display panel (110) may include at least a portion of the display (1010) of FIG. 10 or correspond to at least a portion of the display (1010) of FIG. 10.

[0045] The display panel (110) can be used to display images, screens, information, and / or data.

[0046] The display panel (110) may be configured to be at least partially deformed based on the user input. The display panel (110) may include a conductive material (140). The conductive material (140) may be included within the display panel (110) to sense, detect, identify, discover, recognize, examine, verify, or check for at least partial deformation of the display panel (110), as described above.

[0047] The display driving circuit (132) may include at least a portion of the DDI (1030) of FIG. 10 or correspond to at least a portion of the DDI (1030) of FIG. 10.

[0048] The display driving circuit (132) may be used to display images, screens, information, and / or data on the display panel (110). For example, the display driving circuit (132) may receive an image from the processor (131). For example, the display driving circuit (132) may display the received image on the display panel (110).

[0049] The display driving circuit (132) can obtain data on the state of at least a portion of the conductive material (140) to sense, detect, identify, discover, recognize, inspect, confirm, or check at least a partial deformation of the display panel (110). The display driving circuit (132) can transmit the data to the processor (131).

[0050] The processor (131) may include at least a part of the processor (920) of FIG. 9 or may correspond to at least a part of the processor (920) of FIG. 9.

[0051] The processor (131) may be used to sense, detect, identify, discover, recognize, examine, verify, or check at least partial deformation of the display panel (110). The processor (131) may be used to execute a function corresponding to at least partial deformation of the display panel (110). For example, the processor (131) may receive the data from the display driving circuit (132). For example, the processor (131) may execute a function corresponding to at least partial deformation of the display panel (110) due to the user input based on the data.

[0052] As described above, the conductive material (140) may be embedded within the display panel (110) to sense at least partial deformation of the display panel (110). As a non-limiting example, the conductive material (140) may include indium tin oxide (ITO) or conductive ink. As a non-limiting example, the conductive material (140) may be embedded within the display panel (110) to more accurately sense at least partial deformation of the display panel (110). As a non-limiting example, the conductive material (140) may be embedded within the display panel (110) to provide a faster response to at least partial deformation of the display panel (110). The conductive material (140) may be formed within a pixel definition layer (PDL) of the display panel (110) or included within the PDL of the display panel (110). The PDL may often be referred to as a dielectric layer. For example, the conductive material (140) may be included within the PDL located within an active area. The active area may refer to an area containing sub-pixels that are usable or available for displaying an image. The active area may often be referred to as a display area. For example, the conductive material (140) may be included within the PDL located outside the active area (or within a non-active area). A display panel (110) including a conductive material (140) within the PDL within the active area is exemplified in the description of FIG. 2, and a display panel (110) including a conductive material (140) within the PDL outside the active area is exemplified in the description of FIG. 3.

[0053] FIG. 2 illustrates an example of a display panel including a conductive material within a pixel definition layer (PDL) within an active area.

[0054] FIG. 3 illustrates an example of a display panel including a conductive material within a PDL outside the active area.

[0055] Referring to FIG. 2, the display panel (110-1) may include sub-pixels (230) (or an array of sub-pixels (230)) each including light-emitting elements (or light-emitting diodes (e.g., organic light emitting diodes (OLEDs))) within the active area. The sub-pixels (230) may include sub-pixels of a first set (231). Each of the sub-pixels of the first set (231) may be configured to emit light having a first color (e.g., red). The sub-pixels (230) may include sub-pixels of a second set (232). Each of the sub-pixels of the second set (232) may be configured to emit light having a second color (e.g., green). The sub-pixels (230) may include sub-pixels of a third set (233). Each of the sub-pixels of the third set (233) may be configured to emit light having the second color. The sub-pixels (230) may include sub-pixels of the fourth set (234). Each of the sub-pixels of the fourth set (234) may be configured to emit light having a third color (e.g., blue).

[0056] The display panel (110-1) may include a pixel definition layer (PDL) (not shown in FIG. 2) within the active area. The PDL may define the layout of sub-pixels (230) (or the layout of the array). The PDL may often be referred to as a dielectric layer.

[0057] The display panel (110-1) may include a conductive material (140) within the active area. The conductive material (140) may be included within a portion of the PDL. For example, the conductive material (140) may be formed within the portion of the PDL.

[0058] The conductive material (140) may be uniformly distributed within the active area, as illustrated in FIG. 2. For example, when the conductive material (140) is included only within a portion of the active area, the portion of the active area may appear differently from another portion (or the remaining portion) of the active area due to the conductive material (140). For example, the portion of the active area that appears differently from the other portion of the active area may reduce the visibility (or conspicuity) of the display panel (110-1). For example, the conductive material (140) may be uniformly distributed within the active area for the visibility of the display panel (110-1). As a non-limiting example, the conductive material (140) may be patterned within the portion of the PDL. As a non-limiting example, a portion of the patterned conductive material (140) within said portion of the PDL may be disconnected from another portion of the patterned conductive material (140) within said portion of the PDL. As a non-limiting example, at least one wiring from the portion of the patterned conductive material (140) within said portion of the PDL may be electrically open, unlike at least one wiring from another portion of the patterned conductive material (140) within said portion of the PDL. For example, a portion of the patterned conductive material (140) within said portion of the PDL may be a dummy.

[0059] As a non-limiting example, the conductive material (140) may be patterned within the portion of the PDL based on a first direction (251) (e.g., a vertical direction) and / or a second direction (252) (e.g., a horizontal direction). As a non-limiting example, the conductive material (140) may be patterned within the portion of the PDL based on a third direction (253) (e.g., a diagonal direction) and / or a fourth direction (254) (e.g., the other diagonal direction). For example, the third direction (253) may be between the first direction (251) and the second direction (252) counterclockwise with respect to the first direction (251). For example, the fourth direction (254) may be between the first direction (251) and the second direction (252) clockwise with respect to the first direction (251). However, the present invention is not limited thereto.

[0060] The conductive material (140) may be used to sense at least partial deformation of the display panel (110-1). For example, a portion of the conductive material (140) may be available for sensing at least partial deformation of the display panel (110-1), and another portion (or a remaining portion) of the conductive material (140) may be unavailable for sensing at least partial deformation of the display panel (110-1). For example, if a portion of the display panel (110-1) that is deformed based on the user input is fixed, the portion of the conductive material (140) may be used to sense deformation of the portion of the display panel (110-1), unlike the other portion of the conductive material (140). For example, the portion of the conductive material (140) may be configured to be electrically connected to the display driving circuit (132) (not shown in FIG. 2), and the other portion of the conductive material (140) may be electrically disconnected from the display driving circuit (132).

[0061] As a non-limiting example, the conductive material (140) positioned within the region (240) and the region (242) may include electrodes (241) (or connecting portions (241)) connected to the display driving circuit (132), and the conductive material (140) positioned outside the region (240) and the region (242) may not include electrodes (241). For example, the region (240) and the region (242) may correspond to the portion of the display panel (110-1) configured to be deformed based on the user input.

[0062] Referring to FIG. 3, the display panel (110-2) may include sub-pixels (230) (or an array of sub-pixels (230)) within a first part (310) of the display panel (110-2) including the active area. The sub-pixels (230) may include sub-pixels of a first set (231). Each of the sub-pixels of the first set (231) may be configured to emit light having a first color (e.g., red). The sub-pixels (230) may include sub-pixels of a second set (232). Each of the sub-pixels of the second set (232) may be configured to emit light having a second color (e.g., green). The sub-pixels (230) may include sub-pixels of a third set (233). Each of the sub-pixels of the third set (233) may be configured to emit light having the second color. The sub-pixels (230) may include sub-pixels of the fourth set (234). Each of the sub-pixels of the fourth set (234) may be configured to emit light having a third color (e.g., blue). However, the present invention is not limited thereto. For example, the sub-pixels (230) may include a first set of sub-pixels configured to emit light having the first color, a second set of sub-pixels configured to emit light having the second color, a third set of sub-pixels configured to emit light having the third color, and a fourth set of sub-pixels configured to emit light having a fourth color (e.g., white).

[0063] The display panel (110-2) may include a PDL (not shown in FIG. 3) within the first part (310). The PDL may define the layout of the sub-pixels (230). The PDL may often be referred to as a dielectric layer.

[0064] The display panel (110-2) may include dummy sub-pixels (330) within the second part (320) of the display panel (110-2) including the non-active area. The dummy sub-pixels (330) may represent sub-pixels that are unavailable for displaying an image. The dummy sub-pixels (330) may represent nonfunctional sub-pixels. The dummy sub-pixels (330) may represent sub-pixels located within a bezel (or dead space) surrounding the periphery of the active area. For example, the dummy sub-pixels (330) may include sub-pixels of a first set (331), sub-pixels of a second set (332), sub-pixels of a third set (333), and / or sub-pixels of a fourth set (334). However, the present invention is not limited thereto. For example, each of the dummy sub-pixels (330) (or at least some of the sub-pixels (330)) may include one or more TFTs without a light-emitting element (e.g., an OLED). For example, each of the dummy sub-pixels (330) (or at least some of the sub-pixels (330)) may include one or more TFTs and another part of the light-emitting element (e.g., an anode electrode) without another part of the light-emitting element.

[0065] As a non-limiting example, dummy sub-pixels (330) may be placed to reduce the loading effect (or macro loading effect).

[0066] The display panel (110-2) may include a PDL (not shown in FIG. 3) within the second part (320). The PDL may define the layout of dummy sub-pixels (330). The PDL may often be referred to as a dielectric layer.

[0067] The display panel (110-2) may include a conductive material (140) within the second part (320). For example, unlike the first part (310), the second part (320) may include a conductive material (140). The conductive material (140) may be included within a portion of the PDL positioned within the second part (320). For example, the conductive material (140) may be formed within a portion of the PDL positioned within the second part (320).

[0068] As a non-limiting example, the conductive material (140) within the second part (320) may be distributed non-uniformly within the second part (320), unlike the conductive material (140) included within the active area (e.g., the conductive material (140) of FIG. 2 ). For example, because the conductive material (140) within the second part (320) is not visible from the front surface of the electronic device including the display panel (110-2), the conductive material (140) may be distributed non-uniformly within the second part (320).

[0069] For example, the conductive material (140) may be used to sense at least partial deformation of the display panel (110-2). As a non-limiting example, since the conductive material (140) may be unevenly distributed within the second part (320), all of the conductive material (140) within the second part (320) may be configured to be electrically connected to the display driving circuit (132) (not shown in FIG. 3).

[0070] As a non-limiting example, the conductive material (140) positioned within regions (341), (342), and (343) may include electrodes (241) (or connecting portions (241)) connected to the display driving circuit (132). For example, regions (341), (342), and (343) may correspond to portions of the display (110-2) configured to be deformed based on the user input.

[0071] As described above, the conductive material (140) may be included in a part of the display panel (110-1) including the active area, or may be included in a part (e.g., the second part (320)) of the display panel (110-2) including the non-active area. As described above, the conductive material (140) may be formed within the PDL. The conductive material (140) formed within the PDL is exemplified in the description of FIG. 4.

[0072] FIG. 4 is a cross-sectional view showing an example of a display panel cut along line AA' of FIG. 2 or line A-A' of FIG. 3.

[0073] Referring to FIG. 4, a display panel (e.g., display panel (110-1) or display panel (110-2)) may include a switch layer (400) (or circuit layer (400)) including thin film transistors (TFTs) configured to electrically connect a display driving circuit (132) to a first electrode layer (402), a PDL (401) disposed on the switch layer (400), a first electrode layer (402) disposed between the PDL (401) on the switch layer (400), a light-emitting layer (403) disposed between the PDL (401) on the first electrode layer (402), and a second electrode layer (404) disposed over the PDL (401) and the light-emitting layer (403). For example, the second electrode layer (404) may be surrounded by an encapsulation layer (405).

[0074] The switch layer (400) may be disposed on or within a substrate, although not illustrated in FIG. 4. As a non-limiting example, the substrate may be formed of a bendable material such as polyimide (PI). For example, each of the TFTs may include a low-temperature polycrystalline silicon (LTPS) TFT or a low-temperature polycrystalline oxide (LTPO) TFT.

[0075] The first electrode layer (402) may include an anode printed within the first electrode layer (402).

[0076] The light-emitting layer (403) can cover the anode printed within the first electrode layer (402). For example, a portion of the light-emitting layer (403) can be in contact with the first electrode layer (402). For example, the light-emitting layer (403) can be interposed between the first electrode layer (402) and the second electrode layer (404).

[0077] The second electrode layer (404) may include a cathode.

[0078] For example, the first electrode layer (402), the light-emitting layer (403), and the second electrode layer (404) can form the light-emitting diodes illustrated in the description of FIG. 2.

[0079] The PDL (401) may be positioned along the edge of the first electrode layer (402). For example, the PDL (401) may contact a side surface of the first electrode layer (402). For example, the PDL (401) may at least partially surround the first electrode layer (402).

[0080] The PDL (401) may be positioned along an edge of the light-emitting layer (403). For example, the PDL (401) may contact a side surface of the light-emitting layer (403). For example, the PDL (401) may at least partially surround the light-emitting layer (403).

[0081] The PDL (401) may further include a conductive material (140). At least a portion of the conductive material (140) may be configured to be electrically connected to the display driving circuit (132) via a wiring (410) (or electrodes (241)) formed within the switch layer (400). For example, the first electrode layer (402) within the active area may be connected to the TFTs via at least one wiring (411).

[0082] As a non-limiting example, since the conductive material (140) is included within the PDL (401), the conductive material (140) can more accurately sense at least partial deformation of the display panel (110) (e.g., display panel (110-1) or display panel (110-2). As a non-limiting example, since the conductive material (140) is included within the PDL (401), the conductive material (140) can more quickly provide a response to at least partial deformation of the display panel (110).

[0083] For example, the display driver circuit (132) may provide or transmit to the display panel (110) first signals for displaying an image on the display panel (110) and at least one second signal for sensing at least a partial change of the display panel (110) using the conductive material (140). The first signals may be provided through first wires connecting the display driver circuit (132) and the display panel (110), and the at least one second signal may be provided through at least one second wire different from the first wires. For example, the first signals may be provided to the sub-pixels (230) for applying a data voltage. For example, the at least one second signal may be provided to at least a portion of the conductive material (140) for sensing at least a partial change of the display panel (110).

[0084] As a non-limiting example, the size (or width) (or length) of the display driver circuit (132) may be smaller than the size (or width) (or length) of the display panel (110). The difference between the size of the display driver circuit (132) and the size of the display panel (110) may increase the size of the bezel (or the dead space). For example, the direction in which at least some of the first wires extend may be changed within the display panel (110) to reduce the size of the bezel. For example, the direction in which at least one second wire extends may be changed within the display panel (110) to reduce the size of the bezel. The at least some of the first wires and the at least one second wire are exemplified in the description of FIG. 5A.

[0085] Figure 5a illustrates an example of a connection relationship between a display driving circuit and a display panel.

[0086] Referring to FIG. 5A, the display panel (110) may include wires (510) formed in a first direction (501) and connected to sub-pixels (230) (not shown in FIG. 5A).

[0087] For example, the display (130) may include first wires (511) extending from the display driving circuit (132) to wires (510) and at least one second wire (512) extending from the display driving circuit (132) to a conductive material (140).

[0088] For example, a portion (511-1) of the first wires (511) may include a part (513) extending in a first direction (501) within the display panel (110) and a part (514) extending from the part (513) in a third direction (503) perpendicular to the first direction (501) in order to reduce the size of the bezel (500). For example, a portion (511-2) of the first wires (511) may include a part (517) extending in a first direction (501) within the display panel (110) and a part (518) extending from the part (517) in a second direction (502) perpendicular to the first direction (501) and opposite to the third direction (503) in order to reduce the size of the bezel (500).

[0089] For example, at least one second wire (512) may include a part (515) extending in a first direction (501) and a part (516) extending from the part (515) to the conductive part (140) (or an electrode of the conductive part (140)) in a second direction (502).

[0090] As a non-limiting example, the first layer in which part (515) is formed may be different from the second layer in which part (516) is formed to reduce interference to and / or from other signals. The first layer and the second layer are exemplified within the description of FIG. 5b.

[0091] Fig. 5b is a cross-sectional view showing an example of a display panel cut along ABC of Fig. 5a.

[0092] Referring to FIG. 5B, the switch layer (400) may include a first layer (561) and a second layer (562) below the first layer (561). As a non-limiting example, at least a portion of the first layer (561) and / or at least a portion of the second layer (562) may be used to arrange wires for providing data voltages.

[0093] At least one part (515) of the second wiring (512) can be formed within the first layer (561). At least one part (516) of the second wiring (512) can be formed within the second layer (562). For example, since the part (515) is formed within the first layer (561) and the part (516) is formed within the second layer (562), the at least one second wiring (512) can include a via part (551) connecting the part (515) and the part (516). For example, the conductive material (140) can include a via part (552) connecting the part (516) to the conductive material (140). As a non-limiting example, a portion of the via part (552) can correspond to the wiring (410).

[0094] As a non-limiting example, the switch layer (400) may further include a third layer (563) on the first layer (461). For example, a portion of the via part (552) may be formed within the third layer (563).

[0095] For example, the display driving circuit (132) may obtain data on the state of at least a portion of the conductive material (140) exemplified above and transmit the data to the processor (131). For example, the processor (131) may execute a function corresponding to at least a partial deformation of the display panel (110) due to the user input based on the data received from the display driving circuit (132). For example, the data may represent a resistance value of at least a portion of the conductive material (140). For example, the shape of the conductive material (140) may change according to the at least partial deformation of the display panel (110). For example, the conductive material (140) may have different resistance values ​​depending on its shape. For example, if the conductive material (140) has a first length, the resistance value of the conductive material (140) may be a first value, and if the conductive material (140) has a second length that is changed from the first length, the resistance value of the conductive material (140) may be a second value. As a non-limiting example, the data may be configured with a voltage value representing the resistance value of at least a portion of the conductive material (140).

[0096] For example, the display driving circuit (132) can obtain the data and transmit the data to the processor (131) based on applying a voltage to at least a portion of the conductive material (140).

[0097] For example, the location within the display panel (110) that includes the conductive material (140) may vary depending on the type of electronic device that includes the display panel (110).

[0098] For example, if the electronic device including the display panel (110) is a foldable electronic device, the conductive material (140) may be positioned within the folding part of the display panel (110). The conductive material (140) positioned within the folding part is exemplified in the description of FIG. 6A.

[0099] FIG. 6A illustrates an example of a foldable electronic device having a display panel including a conductive material within a PDL.

[0100] Referring to FIG. 6A, a display panel (110) within a foldable electronic device may include a first planar part (601), a second planar part (602) facing the first planar part (601) in a folded state of the foldable electronic device, and a folding part (603) positioned between the first planar part (601) and the second planar part (602) so as to be bent between an unfolded state (e.g., state (680)) of the foldable electronic device and the folded state. For example, the folding part (603) may connect the first planar part (601) and the second planar part (602).

[0101] For example, at least a portion of the conductive material (140) may be disposed within the folding part (603). For example, at least a portion of the conductive material (140) may be disposed across an axis (610) for rotation of the second planar part (602) with respect to the first planar part (601). For example, the conductive material (140) may be disposed across the axis (610) such that the resistance value of at least a portion of the conductive material (140) is changed.

[0102] For example, the conductive material (140) may have a first resistance value within a state (680) corresponding to the unfolded state. For example, the conductive material (140) may have a second resistance value (e.g., the second resistance value higher than the first resistance value) different from the first resistance value within a state (690) corresponding to a partially folded state between the folded state and the unfolded state.

[0103] For example, the display driving circuit (132) can obtain the data representing the first resistance value (or the data representing the first voltage value corresponding to the first resistance value) and transmit the data to the processor (131). The processor (131) can recognize the state (680) based on the data. For example, the display driving circuit (132) can obtain the data representing the second resistance value (or the data representing the second voltage value corresponding to the second resistance value) and transmit the data to the processor (131). The processor (131) can recognize the state (690) based on the data. For example, the processor (131) can obtain information about the angle between the flat part (601) and the flat part (602) from the data.

[0104] For example, the display driving circuit (132) can obtain the data by applying a first voltage to the conductive material (140) and measuring or obtaining a second voltage representing the resistance value of the conductive material (140). Obtaining the data is exemplified in the description of FIG. 6B.

[0105] FIG. 6B illustrates components of a display driving circuit within a foldable electronic device for obtaining data on the state of at least a portion of a conductive material.

[0106] Referring to FIG. 6b, the display driving circuit (132) may include a sensing circuit (650), a switch (651), a switch (652), and a power amplifier (PA) (653).

[0107] For example, the switch (651) may be configured to connect the PA (653) and the conductive material (140) or to disconnect the conductive material (140) from the PA (653). For example, the switch (652) may be configured to connect the sensing circuit (650) and the conductive material (140) or to disconnect the conductive material (140) from the sensing circuit (650).

[0108] For example, the display driving circuit (132) can control the switch (651) to connect the PA (653) and the conductive material (140) to apply the first voltage (V1) obtained using the PA (653) to the conductive material (140). For example, the display driving circuit (132) can control the switch (652) to connect the conductive material (140) and the sensing circuit (650) to obtain a second voltage (V2) representing the resistance value of the conductive material (140) while the PA (653) is connected to the conductive material (140) (or while the first voltage (V1) is applied to the conductive material (140). For example, the display driving circuit (132) can transmit data representing the second voltage (V2) obtained through the sensing circuit (650) to the processor (131).

[0109] For example, the display driving circuit (132) can periodically control the switch (651) and the switch (652). For example, the period of the pulse signal provided to the switch (651) to control the switch (651) may correspond to the period of the pulse signal provided to the switch (652) to control the switch (652). For example, the duty cycle of the pulse signal provided to the switch (651) to control the switch (651) may correspond to the duty cycle of the pulse signal provided to the switch (652) to control the switch (652). For example, the offset of the pulse signal provided to the switch (651) to control the switch (651) may correspond to the offset of the pulse signal provided to the switch (652) to control the switch (652).

[0110] Although FIG. 6B illustrates a conductive material (140) implemented as a single variable resistor, this is merely exemplary. For example, the conductive material (140) may be implemented as a plurality of resistors. For example, the plurality of resistors may include one or more variable resistors. For example, the plurality of resistors may form at least a portion of a bridge circuit (e.g., a Wheatstone bridge circuit). For example, the bridge circuit may be used to compensate for changes in resistance value due to temperature.

[0111] For example, if the electronic device including the display panel (110) is a rollable electronic device, at least a portion of the conductive material (140) may be disposed within a part that can be rolled into the housing of the electronic device. The conductive material (140) disposed within the part is exemplified in the description of FIG. 7A.

[0112] FIG. 7A illustrates an example of a rollable (or slidable) electronic device having a display panel including a conductive material within a PDL.

[0113] Referring to FIG. 7A, a display panel (110) within a rollable electronic device may include a part (710) that can be rolled into the housing (not shown in FIG. 7A) to change the size of an area visible from a front surface of the housing of the rollable electronic device. For example, conductive materials (140-1), conductive materials (140-2), and conductive materials (140-3) may be disposed within the part (710). For example, conductive materials (140-1), conductive materials (140-2), and conductive materials (140-3) may be disposed along a direction (705) in which the part (710) (or display panel (110)) moves within the housing.

[0114] For example, in a state (701) where the part (710) is positioned outside the housing, each of the conductive material (140-1), the conductive material (140-2), and the conductive material (140-3) may have a first resistance value. For example, in a state (702) where the part (710) is partially rolled up, the conductive material (140-1) may have a second resistance value different from the first resistance value, and each of the conductive material (140-2) and the conductive material (140-3) may have the first resistance value. For example, in a state (703) where the part (710) is further partially rolled up, each of the conductive material (140-1) and the conductive material (140-2) may have the second resistance value, and the conductive material (140-3) may have the first resistance value. For example, in a state where the part (710) is completely dried (704), each of the conductive material (140-1), the conductive material (140-2), and the conductive material (140-3) may have the second resistance value.

[0115] The above descriptions assume that the partially rolled part (710) has one (or single) curvature, but this is merely exemplary. The partially rolled part (710) may have various curvatures. For example, when the partially rolled part (710) has various curvatures, the resistance value of the conductive material (140-1) within the state (703) may be different from the resistance value of the conductive material (140-2) within the state (703). For example, when the partially rolled part (710) has various curvatures, the resistance value of the conductive material (140-1) within the state (704), the resistance value of the conductive material (140-2) within the state (704), and the resistance value of the conductive material (140-3) within the state (704) may be different from each other.

[0116] For example, within the state (701), the display driving circuit (132) may obtain data indicating the first resistance value as data on the state of the conductive material (140-1), obtain data indicating the first resistance value as data on the state of the conductive material (140-2), and obtain data indicating the first resistance value as data on the state of the conductive material (140-3). For example, the display driving circuit (132) may transmit data indicating the first resistance value as data on the state of the conductive material (140-1) to the processor (131), transmit data indicating the first resistance value as data on the state of the conductive material (140-2) to the processor (131), and transmit data indicating the first resistance value as data on the state of the conductive material (140-3) to the processor (131). The processor (131) can recognize the state (701) based on the data indicating the first resistance value received as data on the state of the conductive material (140-1), the data indicating the first resistance value received as data on the state of the conductive material (140-2), and the data indicating the first resistance value received as data on the state of the conductive material (140-3). For example, the processor (131) can recognize the size of the area (711) that is visible from the front surface of the housing based on the data indicating the first resistance value received as data on the state of the conductive material (140-1), the data indicating the first resistance value received as data on the state of the conductive material (140-2), and the data indicating the first resistance value received as data on the state of the conductive material (140-3).

[0117] For example, within the state (702), the display driving circuit (132) may obtain data representing the second resistance value as data on the state of the conductive material (140-1), obtain data representing the first resistance value as data on the state of the conductive material (140-2), and obtain data representing the first resistance value as data on the state of the conductive material (140-3). For example, the display driving circuit (132) may transmit data representing the second resistance value as data on the state of the conductive material (140-1) to the processor (131), transmit data representing the first resistance value as data on the state of the conductive material (140-2) to the processor (131), and transmit data representing the first resistance value as data on the state of the conductive material (140-3) to the processor (131). The processor (131) can recognize the state (702) based on the data indicating the second resistance value received as data on the state of the conductive material (140-1), the data indicating the first resistance value received as data on the state of the conductive material (140-2), and the data indicating the first resistance value received as data on the state of the conductive material (140-3). For example, the processor (131) can recognize the size of the area (711) viewable from the front surface of the housing based on the data indicating the second resistance value received as data on the state of the conductive material (140-1), the data indicating the first resistance value received as data on the state of the conductive material (140-2), and the data indicating the first resistance value received as data on the state of the conductive material (140-3).

[0118] For example, within the state (703), the display driving circuit (132) may obtain data representing the second resistance value as data on the state of the conductive material (140-1), obtain data representing the second resistance value as data on the state of the conductive material (140-2), and obtain data representing the first resistance value as data on the state of the conductive material (140-3). For example, the display driving circuit (132) may transmit data representing the second resistance value as data on the state of the conductive material (140-1) to the processor (131), transmit data representing the second resistance value as data on the state of the conductive material (140-2) to the processor (131), and transmit data representing the first resistance value as data on the state of the conductive material (140-3) to the processor (131). The processor (131) can recognize the state (703) based on the data indicating the second resistance value received as data on the state of the conductive material (140-1), the data indicating the second resistance value received as data on the state of the conductive material (140-2), and the data indicating the first resistance value received as data on the state of the conductive material (140-3). For example, the processor (131) can recognize the size of the area (711) visible from the front surface of the housing based on the data indicating the second resistance value received as data on the state of the conductive material (140-1), the data indicating the second resistance value received as data on the state of the conductive material (140-2), and the data indicating the first resistance value received as data on the state of the conductive material (140-3).

[0119] For example, within the state (704), the display driving circuit (132) may obtain data indicating the second resistance value as data on the state of the conductive material (140-1), obtain data indicating the second resistance value as data on the state of the conductive material (140-2), and obtain data indicating the second resistance value as data on the state of the conductive material (140-3). For example, the display driving circuit (132) may transmit data indicating the second resistance value as data on the state of the conductive material (140-1) to the processor (131), transmit data indicating the second resistance value as data on the state of the conductive material (140-2) to the processor (131), and transmit data indicating the second resistance value as data on the state of the conductive material (140-3) to the processor (131). The processor (131) can recognize the state (704) based on the data indicating the second resistance value received as data on the state of the conductive material (140-1), the data indicating the second resistance value received as data on the state of the conductive material (140-2), and the data indicating the second resistance value received as data on the state of the conductive material (140-3). For example, the processor (131) can recognize the size of the area (711) that is visible from the front surface of the housing based on the data indicating the second resistance value received as data on the state of the conductive material (140-1), the data indicating the second resistance value received as data on the state of the conductive material (140-2), and the data indicating the second resistance value received as data on the state of the conductive material (140-3).

[0120] For example, the display driving circuit (132) can obtain data on the conductive material (140-1), data on the conductive material (140-2), and data on the conductive material (140-3) by applying a first voltage to each of the conductive material (140-1), the conductive material (140-2), and the conductive material (140-3) and measuring or obtaining a second voltage representing the resistance value of each of the conductive material (140-1), the conductive material (140-2), and the conductive material (140-3). Obtaining data on the conductive material (140-1), data on the conductive material (140-2), and data on the conductive material (140-3) is exemplified in the description of FIG. 7B.

[0121] FIG. 7b illustrates components of a display drive circuit within a rollable electronic device for obtaining data on the state of at least a portion of a conductive material.

[0122] Referring to FIG. 7b, the display driving circuit (132) may include a sensing circuit (650), a switch (651-1), a switch (651-2), a switch (651-3), a switch (652-1), a switch (652-2), a switch (652-3), a PA (653-1), a PA (653-2), and a PA (653-3).

[0123] For example, the switch (651-1) may be configured to connect the PA (653-1) and the conductive material (140-1) or to disconnect the conductive material (140-1) from the PA (653-1). For example, the switch (652-1) may be configured to connect the sensing circuit (650) and the conductive material (140-1) or to disconnect the conductive material (140-1) from the sensing circuit (650).

[0124] For example, the switch (651-2) may be configured to connect the PA (653-2) and the conductive material (140-2) or to disconnect the conductive material (140-2) from the PA (653-2). For example, the switch (652-2) may be configured to connect the sensing circuit (650) and the conductive material (140-2) or to disconnect the conductive material (140-2) from the sensing circuit (650).

[0125] For example, the switch (651-3) may be configured to connect the PA (653-3) and the conductive material (140-3) or to disconnect the conductive material (140-3) from the PA (653-3). For example, the switch (652-3) may be configured to connect the sensing circuit (650) and the conductive material (140-3) or to disconnect the conductive material (140-3) from the sensing circuit (650).

[0126] For example, the display driving circuit (132) can control the switch (651-1) to connect the PA (653-1) and the conductive material (140-1) to apply the first voltage (V1) obtained using the PA (653-1) to the conductive material (140-1). For example, the display driving circuit (132) can control the switch (652-1) to connect the conductive material (140-1) and the sensing circuit (650) to obtain the second voltage (V2) representing the resistance value of the conductive material (140-1) while the PA (653-1) is connected to the conductive material (140-1) (or while the first voltage (V1) is applied to the conductive material (140-1)). For example, the display driving circuit (132) can transmit data representing the second voltage (V2) obtained through the sensing circuit (650) to the processor (131) as data on the state of the conductive material (140-1).

[0127] For example, the display driving circuit (132) can control the switch (651-2) to connect the PA (653-2) and the conductive material (140-2) to apply the first voltage (V1) obtained using the PA (653-2) to the conductive material (140-2). For example, the display driving circuit (132) can control the switch (652-2) to connect the conductive material (140-2) and the sensing circuit (650) to obtain the second voltage (V2) representing the resistance value of the conductive material (140-2) while the PA (653-2) is connected to the conductive material (140-2) (or while the first voltage (V1) is applied to the conductive material (140-1)). For example, the display driving circuit (132) can transmit data representing the second voltage (V2) obtained through the sensing circuit (650) to the processor (131) as data on the state of the conductive material (140-2).

[0128] For example, the display driving circuit (132) can control the switch (651-3) to connect the PA (653-3) and the conductive material (140-3) to apply the first voltage (V1) obtained using the PA (653-3) to the conductive material (140-3). For example, the display driving circuit (132) can control the switch (652-3) to connect the conductive material (140-3) and the sensing circuit (650) to obtain the second voltage (V2) representing the resistance value of the conductive material (140-3) while the PA (653-3) is connected to the conductive material (140-3) (or while the first voltage (V1) is applied to the conductive material (140-3)). For example, the display driving circuit (132) can transmit data representing the second voltage (V2) obtained through the sensing circuit (650) to the processor (131) as data on the state of the conductive material (140-3).

[0129] The above control of switch (651-1), the above control of switch (651-2), the above control of switch (651-3), the above control of switch (652-1), the above control of switch (652-2), and the above control of switch (652-3) are exemplified in the description of Fig. 7c.

[0130] Figure 7c illustrates an exemplary method for controlling the switches of Figure 7b.

[0131] Referring to FIG. 7c, within a time interval (721), the display driving circuit (132) can control the switch (651-1) to connect the conductive material (140-1) to the PA (653-1) and control the switch (652-1) to connect the sensing circuit (650) to the conductive material (140-1).

[0132] For example, within a time interval (722) following a time interval (721), the display driving circuit (132) can control a switch (651-2) to connect a conductive material (140-2) to a PA (653-2) and control a switch (652-2) to connect a sensing circuit (650) to the conductive material (140-2). For example, the length of the time interval (722) can correspond to the length of the time interval (721).

[0133] For example, within a time interval (723) following a time interval (722), the display driving circuit (132) can control a switch (651-3) to connect a conductive material (140-3) to a PA (653-3) and control a switch (652-3) to connect a sensing circuit (650) to the conductive material (140-3). For example, the length of the time interval (723) can correspond to the length of the time interval (721).

[0134] For example, the display driving circuit (132) can periodically control switch (651-1), switch (651-2), switch (651-3), switch (652-1), switch (652-2), and switch (652-3).

[0135] For example, the period of the pulse signal provided to the switch (651-1) to control the switch (651-1) may correspond to the period of the pulse signal provided to the switch (652-1) to control the switch (652-1). For example, the duty cycle of the pulse signal provided to the switch (651-1) to control the switch (651-1) may correspond to the duty cycle of the pulse signal provided to the switch (652-1) to control the switch (652-1). For example, the offset of the pulse signal provided to the switch (651-1) to control the switch (651-1) may correspond to the offset of the pulse signal provided to the switch (652-1) to control the switch (652-1).

[0136] For example, the period of the pulse signal provided to the switch (651-2) to control the switch (651-2) may correspond to the period of the pulse signal provided to the switch (652-2) to control the switch (652-2). For example, the period of the pulse signal provided to the switch (651-2) to control the switch (651-2) may correspond to the period of the pulse signal provided to the switch (651-1) to control the switch (651-1). For example, the duty cycle of the pulse signal provided to the switch (651-2) to control the switch (651-2) may correspond to the duty cycle of the pulse signal provided to the switch (652-2) to control the switch (652-2). For example, the duty cycle of the pulse signal provided to the switch (651-2) to control the switch (651-2) may correspond to the duty cycle of the pulse signal provided to the switch (651-1) to control the switch (651-1). For example, the offset of the pulse signal provided to the switch (651-2) to control the switch (651-2) may correspond to the offset of the pulse signal provided to the switch (652-2) to control the switch (652-2). For example, the offset of the pulse signal provided to the switch (651-2) to control the switch (651-2) may be different from the offset of the pulse signal provided to the switch (651-1) to control the switch (651-1).

[0137] For example, the period of the pulse signal provided to the switch (651-3) to control the switch (651-3) may correspond to the period of the pulse signal provided to the switch (652-3) to control the switch (652-3). For example, the period of the pulse signal provided to the switch (651-3) to control the switch (651-3) may correspond to the period of the pulse signal provided to the switch (651-1) to control the switch (651-1). For example, the duty cycle of the pulse signal provided to the switch (651-3) to control the switch (651-3) may correspond to the duty cycle of the pulse signal provided to the switch (652-3) to control the switch (652-3). For example, the duty cycle of the pulse signal provided to the switch (651-3) to control the switch (651-3) may correspond to the duty cycle of the pulse signal provided to the switch (651-1) to control the switch (651-1). For example, the offset of the pulse signal provided to the switch (651-3) to control the switch (651-3) may correspond to the offset of the pulse signal provided to the switch (652-3) to control the switch (652-3). For example, the offset of the pulse signal provided to the switch (651-3) to control the switch (651-3) may be different from the offset of the pulse signal provided to the switch (651-1) to control the switch (651-1). For example, the offset of the pulse signal provided to the switch (651-3) to control the switch (651-3) may be different from the offset of the pulse signal provided to the switch (651-2) to control the switch (651-2).

[0138] For example, the display driving circuit (132) can transmit data representing the second voltage (V2) acquired within a time interval (721) through the sensing circuit (650) to the processor (131) as data on the state of the conductive material (140-1). For example, the display driving circuit (132) can transmit data representing the second voltage (V2) acquired within a time interval (722) through the sensing circuit (650) to the processor (131) as data on the state of the conductive material (140-2). For example, the display driving circuit (132) can transmit data representing the second voltage (V2) acquired within a time interval (723) through the sensing circuit (650) to the processor (131) as data on the state of the conductive material (140-3). Data representing the second voltage (V2) acquired within the time interval (721), data representing the second voltage (V2) acquired within the time interval (722), and data representing the second voltage (V2) acquired within the time interval (723) are exemplified in the description of FIG. 7d.

[0139] Figure 7d illustrates an example of data for the state of at least a portion of the conductive material.

[0140] Referring to FIG. 7d, the horizontal axis of the chart (750) represents time, and the vertical axis of the chart (750) represents voltage. A line (751) in the chart (750) represents data representing a second voltage (V2) acquired within a time interval (721), a line (752) in the chart (750) represents data representing a second voltage (V2) acquired within a time interval (722), and a line (753) in the chart (750) represents data representing a second voltage (V2) acquired within a time interval (723).

[0141] For example, the processor (131) can recognize a state (704) changed from state (701) through state (702) and state (703) based on a change in data within a time interval (721) represented by line (751), a change in data within a time interval (722) represented by line (752), and a change in data within a time interval (723) represented by line (753).

[0142] The above descriptions illustrate examples in which the change in data represented by line (751) within time interval (721), the change in data represented by line (752) within time interval (722), and the change in data represented by line (753) within time interval (723) are the same, but this is merely exemplary. For example, if the partially rolled part (710) has various curvatures, the change in data represented by line (751) within time interval (721), the change in data represented by line (752) within time interval (722), and the change in data represented by line (753) within time interval (723) may be different from each other.

[0143] For example, the processor (131) may execute a function corresponding to the state (704) based on recognition of the state (704). An example of the function is illustrated in the description of FIG. 7e.

[0144] Figure 7e illustrates an example of a function that is executed based on data about the state of at least a portion of a challenging material.

[0145] Referring to FIG. 7E, the processor (131) may sense, detect, recognize, or identify a state (704) changed from a state (701) based at least in part on the operations illustrated in the descriptions of FIGS. 7A to 7D. For example, the processor (131) may perform the above function by acquiring or generating a screen (791) corresponding to the size of the viewable area (711) from the front surface of the housing (790) within the state (704), and transmitting information about the screen (791) to the display driving circuit (132) for displaying the screen (791).

[0146] For example, the processor (131) may transmit information about the screen (791) to the display driving circuit (132) to display a panel (761) having a second size smaller than the first size of a bar-shaped panel (e.g., an edge panel) (761) displayed on the display panel (110) within the state (701).

[0147] As a non-limiting example, the processor (131) may transmit to the display driving circuit (132) information about an image to be displayed on a portion of the display panel (110) that is not visible from the front surface of the housing (790) within a state (704) changed from a state (701). For example, the information about the image may be included within the information about the screen (791). For example, the information about the image may be transmitted together with the information about the screen (791). For example, the image may be displayed on the portion of the display panel (110) to reduce the probability that an afterimage occurs within the portion of the display panel (110) when the state (704) is changed to the state (701).

[0148] For example, if the electronic device including the display panel (110) is a stretchable electronic device, the conductive material (140) configured to be electrically connected to the display driving circuit (132) may be uniformly distributed within the display panel (110). For example, the conductive material (140) may be patterned within the display panel (110). The conductive material (140) patterned within the display panel (110) is exemplified within the description of FIG. 8.

[0149] FIG. 8 illustrates an example of a conductive material included within a stretchable display panel.

[0150] Referring to FIG. 8, a display panel (110) within a stretchable electronic device may have a part that is at least partially deformable but not fixed. For example, the display panel (110) may be randomly deformed or stretched, as indicated by arrows (800). For example, the display panel (110) may include a first set (811) of conductive materials (140) having a longitudinal direction corresponding to a direction (801) and a second set (812) of conductive materials (140) having a longitudinal direction corresponding to a direction (803) perpendicular to the direction (801). For example, the first set (811) of conductive materials (140) may be disposed between the second set (812) of conductive materials. For example, the conductive material (140) of the first set (811) and the conductive material (140) of the second set (812) can be patterned. For example, the conductive material (140) of the first set (811) and the conductive material (140) of the second set (812) can form a pattern.

[0151] As a non-limiting example, a portion of the display panel (110) may be rigid, and another portion of the display panel (110) may be flexible or deformable. For example, the display panel (110) may include sub-pixels (830). For example, the display panel (110) may include wirings (840) for the sub-pixels (830). For example, the portion of the rigid display panel (110) may include sub-pixels (830), while the other portion of the flexible display panel (110) may include wirings (840) for the sub-pixels (830). For example, each of the sub-pixels (830) may include a light-emitting element (e.g., a light-emitting diode) and one or more transistors used to emit light. For example, each of the sub-pixels (830) may further include a display driving circuit (132) for each of the sub-pixels (830). For example, some of the sub-pixels (830) may include a conductive material (140) of a first set (811), and other some of the sub-pixels (830) may include a conductive material (140) of a second set (812).

[0152] The electronic devices exemplified above may be implemented as an electronic device (901) within the description below. The electronic device (901) may include a display panel (110) (e.g., a part of the display module (960) of FIG. 9 or the display (1010) of FIG. 10).

[0153] FIG. 9 is a block diagram of an electronic device (901) within a network environment (900) according to various embodiments. Referring to FIG. 9, in the network environment (900), the electronic device (901) may communicate with the electronic device (902) via a first network (998) (e.g., a short-range wireless communication network), or may communicate with at least one of the electronic device (904) or the server (908) via a second network (999) (e.g., a long-range wireless communication network). In one embodiment, the electronic device (901) may communicate with the electronic device (904) via the server (908). According to one embodiment, the electronic device (901) may include a processor (920), a memory (930), an input module (950), an audio output module (955), a display module (960), an audio module (970), a sensor module (976), an interface (977), a connection terminal (978), a haptic module (979), a camera module (980), a power management module (988), a battery (989), a communication module (990), a subscriber identification module (996), or an antenna module (997). In some embodiments, the electronic device (901) may omit at least one of these components (e.g., the connection terminal (978)), or may have one or more other components added. In some embodiments, some of these components (e.g., the sensor module (976), the camera module (980), or the antenna module (997)) may be integrated into one component (e.g., the display module (960)).

[0154] The processor (920) may, for example, execute software (e.g., a program (940)) to control at least one other component (e.g., a hardware or software component) of the electronic device (901) connected to the processor (920) and perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (920) may store commands or data received from other components (e.g., a sensor module (976) or a communication module (990)) in a volatile memory (932), process the commands or data stored in the volatile memory (932), and store result data in a non-volatile memory (934). According to one embodiment, the processor (920) may include a main processor (921) (e.g., a central processing unit or an application processor) or an auxiliary processor (923) (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together with the main processor (921). For example, when the electronic device (901) includes the main processor (921) and the auxiliary processor (923), the auxiliary processor (923) may be configured to use less power than the main processor (921) or to be specialized for a given function. The auxiliary processor (923) may be implemented separately from the main processor (921) or as a part thereof.

[0155] The auxiliary processor (923) may control at least a portion of functions or states associated with at least one component (e.g., a display module (960), a sensor module (976), or a communication module (990)) of the electronic device (901), for example, on behalf of the main processor (921) while the main processor (921) is in an inactive (e.g., sleep) state, or together with the main processor (921) while the main processor (921) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (923) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (980) or a communication module (990)). In one embodiment, the auxiliary processor (923) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (901) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (908)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above. In addition to, or alternatively to, a hardware structure, an artificial intelligence model may include a software structure.

[0156] The memory (930) can store various data used by at least one component (e.g., the processor (920) or the sensor module (976)) of the electronic device (901). The data can include, for example, software (e.g., the program (940)) and input data or output data for commands related thereto. The memory (930) can include a volatile memory (932) or a non-volatile memory (934).

[0157] The program (940) may be stored as software in the memory (930) and may include, for example, an operating system (942), middleware (944), or an application (946).

[0158] The input module (950) can receive commands or data to be used in a component of the electronic device (901) (e.g., a processor (920)) from an external source (e.g., a user) of the electronic device (901). The input module (950) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g., a stylus pen).

[0159] The audio output module (955) can output audio signals to the outside of the electronic device (901). The audio output module (955) can include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0160] The display module (960) can visually provide information to an external party (e.g., a user) of the electronic device (901). The display module (960) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (960) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0161] The audio module (970) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (970) can acquire sound through the input module (950), output sound through the sound output module (955), or an external electronic device (e.g., electronic device (902)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (901).

[0162] The sensor module (976) can detect the operating status (e.g., power or temperature) of the electronic device (901) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (976) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0163] The interface (977) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (901) with an external electronic device (e.g., the electronic device (902)). In one embodiment, the interface (977) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0168] A battery (989) may power at least one component of the electronic device (901). In one embodiment, the battery (989) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0169] The communication module (990) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (901) and an external electronic device (e.g., electronic device (902), electronic device (904), or server (908)), and the performance of communication through the established communication channel. The communication module (990) may operate independently from the processor (920) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (990) may include a wireless communication module (992) (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 (994) (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external electronic device (904) via a first network (998) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (999) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (992) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (996) to verify or authenticate the electronic device (901) within a communication network such as the first network (998) or the second network (999).

[0170] The wireless communication module (992) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency communications (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (992) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (992) may support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (992) may support various requirements specified in the electronic device (901), an external electronic device (e.g., the electronic device (904)), or a network system (e.g., the second network (999)). According to one embodiment, the wireless communication module (992) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0171] The antenna module (997) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (997) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (997) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (998) or the second network (999), may be selected from the plurality of antennas, for example, by the communication module (990). A signal or power may be transmitted or received between the communication module (990) and the external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (997).

[0172] According to various embodiments, the antenna module (997) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0173] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0174] According to one embodiment, commands or data may be transmitted or received between the electronic device (901) and an external electronic device (904) via a server (908) connected to a second network (999).
