[0025] Figure 13 is a schematic diagram of an exemplary AI (artificial intelligence) system.

[0026] Figure 1 illustrates an example of changing the viewing angle of a screen.

[0027] Referring to FIG. 1, an electronic device (100) (e.g., electronic device (1101) of FIG. 11) may display a screen (110) on a display panel (160) (e.g., display panel (160) of FIG. 2, display (1210) of FIG. 12). The screen (110) may include one or more contents (or one or more media contents). The screen (110) may include one or more visual objects. The screen (110) may be displayed on the display panel (160) to provide information.

[0028] The electronic device (100) can display a screen (110) having a viewing angle (181) on a display panel (160). For example, the viewing angle (181) of the screen (110) can be wider than the viewing angle (182) and the viewing angle (183) of the screen (110) described below. For example, the screen (110) having the viewing angle (181) can be displayed on the display panel (160) according to a normal display mode. For example, the viewing angle (181) can be wider than a first critical viewing angle (e.g., viewing angle (182)) and wider than a second critical viewing angle (e.g., viewing angle (183)) that is wider than the first critical viewing angle.

[0029] The electronic device (100) may provide a function (or feature) for user privacy with respect to the display on the display panel (160). For example, the electronic device (100) may provide one or more display modes that narrow the viewing angle of at least a portion of the screen (110) displayed on the display panel (160) for the above function.

[0030] The one or more display modes may include a first privacy display mode. The first privacy display mode may be described as a privacy display mode that provides the first threshold viewing angle (e.g., viewing angle (182)). For example, the electronic device (100) may display a screen (110) having a viewing angle (182) that is the first threshold viewing angle on the display panel (160) according to the first privacy display mode. The first privacy display mode may be changed or converted from the normal display mode. For example, the electronic device (100) may change the display of the screen (110) having the viewing angle (181) to the display of the screen (110) having the viewing angle (182) based on the first privacy display mode changed from the normal display mode. For example, the electronic device (100) may stop (or terminate) (or deactivate) displaying a screen (110) having a viewing angle (181) and display a screen (110) having a viewing angle (182) based on changing the normal display mode to the first privacy display mode. For example, the electronic device (100) may change displaying a screen (110) having a viewing angle (183) to displaying a screen (110) having a viewing angle (182) based on the first privacy display mode changed from the second privacy display mode described below. For example, the electronic device (100) may stop (or terminate) (or deactivate) displaying a screen (110) having a viewing angle (183) and display a screen (110) having a viewing angle (182) based on changing the second privacy display mode to the first privacy display mode.For example, the electronic device (100) may change the display of a screen (110) having a viewing angle (182) to a screen (110) having a viewing angle (181) based on changing the first privacy display mode to the normal display mode. As a non-limiting example, the first threshold viewing angle may be described as the narrowest viewing angle that can be provided through the display panel (160).

[0031] The one or more display modes may include a second privacy display mode. The second privacy display mode may be described as a privacy display mode that provides a viewing angle (e.g., viewing angle (183)) that is wider than the first threshold viewing angle and narrower than or equal to the second threshold viewing angle. The second privacy display mode may be described as a privacy display mode that adjusts visibility from a surrounding space of the display panel (160) (e.g., the second space described below). For example, visibility from a surrounding space of the display panel (160) provided according to the second privacy display mode may be different from visibility from a surrounding space of the display panel (160) provided according to the first privacy display mode.

[0032] For example, the electronic device (100) may display a screen (110) having a viewing angle (183) that is wider than the first threshold viewing angle and narrower than the second threshold viewing angle, on the display panel (160), according to the second privacy display mode. The second threshold viewing angle may be described as the widest viewing angle that can be provided according to the second privacy display mode. The viewing angle (183) may be provided according to the second privacy display mode and may be between the first threshold viewing angle and the second threshold viewing angle. The second privacy display mode may be described as an intermediate display mode between the normal display mode and the first privacy display mode. The second privacy display mode may be described as a display mode that adjusts the viewing angle of a screen displayed on the display panel (160) between the first threshold viewing angle and the second threshold viewing angle. For example, the electronic device (100) can change the display of the screen (110) having the viewing angle (181) to the display of the screen (110) having the viewing angle (183) based on the second privacy display mode changed from the normal display mode. For example, the electronic device (100) can stop (or end) (or deactivate) the display of the screen (110) having the viewing angle (181) and display the screen (110) having the viewing angle (183) based on the change of the normal display mode to the second privacy display mode. For example, the electronic device (100) can change the display of the screen (110) having the viewing angle (182) to the display of the screen (110) having the viewing angle (183) based on the change of the second privacy display mode from the first privacy display mode.For example, the electronic device (100) may stop (or terminate) (or deactivate) displaying the screen (110) having the viewing angle (182) and display the screen (110) having the viewing angle (183) based on changing the first privacy display mode to the second privacy display mode. For example, the electronic device (100) may change displaying the screen (110) having the viewing angle (183) to displaying the screen (110) having the viewing angle (181) based on changing the second privacy display mode to the normal display mode.

[0033] As a non-limiting example, the first privacy display mode and the second privacy display mode may be replaced with a single privacy display mode (or one (a) privacy display mode). For example, the single privacy display mode may be described as a mode that sets the viewing angle of the screen (110) displayed on the display panel (160) to a narrower viewing angle than the viewing angle (181). For example, the normal display mode may be described as a mode that deactivates a function of the electronic device (100) for user privacy, and the single privacy display mode may be described as a mode that activates a function of the electronic device (100) for user privacy. For example, the electronic device (100) may adjust (or change) the viewing angle of the screen (110) displayed on the display panel (160) between the first threshold viewing angle and the second threshold viewing angle, according to the single privacy display mode. The single privacy display mode may also include only the second privacy display mode.

[0034] Figure 2 is a schematic view of an exemplary electronic device.

[0035] Referring to FIG. 2, the electronic device (100) may include at least one processor (210) including a processing circuit, a display (220), and a memory (230). The electronic device (100) may include at least a portion of the electronic device (1101) of FIG. 11 or may correspond to at least a portion of the electronic device (1101) of FIG. 11.

[0036] At least one processor (210) may include at least a portion of the processor (1120) of FIG. 11 or may correspond to at least a portion of the processor (1120) of FIG. 11. The at least one processor (210) may include a central processing unit (CPU) (211) (e.g., including a processing circuit) and a display processing unit (DPU) (212) (e.g., including a processing circuit). As a non-limiting example, the at least one processor (210) may further include a graphics processing unit (GPU) (e.g., including a processing circuit). The at least one processor (210) may be configured to execute instructions stored in a memory (230).

[0037] As a non-limiting example, at least one processor (210) may perform at least some of the operations described below using a trained model (e.g., a generative artificial intelligence (AI) model (1330) of FIG. 13). For example, at least one processor (210) may determine, using the trained model, to change the normal display mode to the first privacy display mode, to change the normal display mode to the second privacy display mode, to change the first privacy display mode to the second privacy display mode, to change the first privacy display mode to the normal display mode, to change the second privacy display mode to the normal display mode, and / or to change the second privacy display mode to the first privacy display mode.

[0038] As a non-limiting example, at least one processor (210) may transmit, to the display driving circuit (221), at least one first command indicating the first privacy display mode based on a determination to change the normal display mode to the first privacy display mode. For example, the display driving circuit (221) may change the normal display mode to the first privacy display mode based on the at least one first command. As a non-limiting example, at least one processor (210) may transmit, to the display driving circuit (221), at least one second command indicating the second privacy display mode based on a determination to change the normal display mode to the second privacy display mode. For example, the display driving circuit (221) may change the normal display mode to the second privacy display mode based on the at least one second command.

[0039] As a non-limiting example, at least one processor (210) may transmit at least one third command indicating the normal display mode to the display driving circuit (221) based on a determination to change the first privacy display mode to the normal display mode. For example, the display driving circuit (221) may change the first privacy display mode to the normal display mode based on the at least one third command. As a non-limiting example, at least one processor (210) may transmit at least one third command to the display driving circuit (221) based on a determination to change the second privacy display mode to the normal display mode. For example, the display driving circuit (221) may change the second privacy display mode to the normal display mode based on the at least one third command.

[0040] The display (220) may include at least a portion of the display module (1160) of FIG. 11 or correspond to at least a portion of the display module (1160) of FIG. 11. The display (220) may include a display driver circuitry (or display driver integrated circuitry) (221) and a display panel (160). The display driver circuitry (221) may include at least a portion of the display driver IC (1230) of FIG. 12 or correspond to at least a portion of the display driver IC (1230) of FIG. 12. As a non-limiting example, the display driver circuitry (221) may perform at least a portion of the operations described below using a trained model (e.g., a generative artificial intelligence (AI) model (1330) of FIG. 13). For example, the display driving circuit (221) can determine the viewing angle of the screen (110) displayed on the display panel (160) while the second privacy display mode (or the single privacy display mode) is activated using the trained model. The display panel (160) can include at least a portion of the display (1210) of FIG. 12 or correspond to at least a portion of the display (1210) of FIG. 12.

[0041] The display (220) may operate or be driven for command mode, video mode, hybrid video mode, and / or adaptive refresh panel (ARP) of MIPI (mobile industry processor interface) DSI (display serial interface).

[0042] The memory (230) may include one or more storage media. For example, the one or more storage media may include a hard drive, flash memory, permanent memory such as read-only memory (ROM), semi-permanent memory such as random access memory (RAM), any other suitable type of storage assembly, or any combination thereof. The memory (230) may include a cache memory, which is one or more different types of memory used to temporarily store data for the function or feature of the electronic device (100). The memory (230) may be fixedly embedded within the electronic device (100) or incorporated into one or more suitable types of components (e.g., a subscriber identity module (SIM) card and / or a secure digital (SD) memory card) that can be repeatedly inserted into and removed from the electronic device (100). For example, the memory (230) may include at least a portion of the memory (1130) of FIG. 11 or correspond to at least a portion of the memory (1130) of FIG. 11.

[0043] The memory (230) may store one or more software applications, such as an operating system software application, a firmware software application, a media playback software application, a media editing software application, a software application for communicating with other users, a translation software application, a digital assistant software application, and / or any other suitable software applications. For example, the one or more software applications may include instructions executable by at least a portion of at least one processor (210).

[0044] For example, the display panel (160) within the display (220) may have a structure for adjusting the viewing angle of a screen (e.g., screen (110)) displayed on the display panel (160). The structure is described in more detail with reference to FIGS. 3 to 6.

[0045] Figure 3 illustrates an example configuration of a display panel of an electronic device.

[0046] Referring to FIG. 3, the display panel (160) may include a plurality of pixels. Each of the pixels may include sub-pixels. The sub-pixels may include a first sub-pixel (350-1) configured to emit light with a first color (e.g., red), a second sub-pixel (350-2) configured to emit light with a second color (e.g., green), and a third sub-pixel (350-3) configured to emit light with a third color (e.g., blue). The sub-pixels may further include a fourth sub-pixel (not shown) configured to emit light with a fourth color (e.g., white).

[0047] The field of illumination (FOI) of light emitted from one or more of the pixels may be narrower than the FOI of light emitted from one or more other of the pixels. For example, the one or more of the pixels may include pixel (321) and pixel (322). For example, the other one or more of the pixels may include pixel (311) and pixel (312).

[0048] For example, one or more of the pixels may be positioned within (or within) a first set (320) of regions within the active area (or display area) of the display panel (160), such as pixels (321) and pixels (322). For example, the other one or more of the pixels may be positioned within (or within) a second set (310) of regions within the active area of ​​the display panel (160), such as pixels (311) and pixels (312). As a non-limiting example, the regions included within the first set (320) of regions and the regions included within the second set (310) of regions may alternate with each other. As a non-limiting example, the regions included within the first set (320) of regions and the regions included within the second set (310) of regions may be included within the active area in an interleaved arrangement.

[0049] The display panel (160) may include an opaque member within another layer (e.g., another layer (402) of FIG. 4) of the display panel (160) disposed above a layer of the display panel (160) including the pixels (e.g., layer (401) of FIG. 4) to narrow (or reduce) the FOI of light emitted from the one or more of the pixels compared to the FOI of light emitted from the other one or more of the plurality of pixels. The opaque member within the other layer of the display panel (160) may be structured to narrow the viewing angle of at least a portion of a screen (e.g., screen (110)) displayed on the display panel (160). The opaque member within the other layer of the display panel (160) may partially overlying the one or more of the pixels and may not overlying the other one or more of the pixels. The opaque member disposed within the other layer of the display panel (160) according to the configuration example of FIG. 3 is described in more detail with reference to FIG. 4.

[0050] FIG. 4 is a cross-sectional view of a display panel according to an example configuration of FIG. 3.

[0051] Referring to FIG. 4, the display panel (160) may include a layer (401) and another layer (402) disposed (or positioned) on the layer (401). The layer (401) of the display panel (160) may be described as a light-emitting layer (401). The other layer (402) of the display panel (160) may be described as a masking layer (402) (or mask layer (402)) (or black matrix layer (402)).

[0052] A layer (401) of a display panel (160) may include a pixel (311) positioned within a region (492) included within a second set (310) of regions and a pixel (321) positioned within a region (491) included within a first set (320) of regions. The pixel (311) may include a sub-pixel (411) and a sub-pixel (412). The pixel (321) may include a sub-pixel (421) and a sub-pixel (422).

[0053] The layer (401) of the display panel (160) may include a pixel definition layer (PDL) (441). The PDL (441) may define the periphery of the pixel (311) and the periphery of the pixel (321). The PDL (441) may define the periphery of the subpixel (411) within the pixel (311) and the periphery of the subpixel (412) within the pixel (311). The PDL (441) may define the periphery of the subpixel (421) within the pixel (321) and the periphery of the subpixel (422) within the pixel (321). For example, the PDL (441) may be disposed between the pixel (311) and the pixel (321), between the subpixel (411) and the subpixel (412), and between the subpixel (421) and the subpixel (422).

[0054] As a non-limiting example, the width (w1) of a sub-pixel (411) defined by a PDL (441) may be equal to the width (w2) of a sub-pixel (421) defined by a PDL (441). For example, when the color of light emitted from a sub-pixel (411) is equal to the color of light emitted from a sub-pixel (421), the width (w1) of the sub-pixel (411) may be equal to the width (w2) of the sub-pixel (421). When the color of light emitted from a sub-pixel (411) is different from the color of light emitted from a sub-pixel (421), the width (w1) of the sub-pixel (411) may be narrower than the width (w2) of the sub-pixel (421). As a non-limiting example, the width (w1) of a sub-pixel (411) defined by a PDL (441) may be wider than the width (w2) of a sub-pixel (421) defined by a PDL (441). For example, when the color of light emitted from a sub-pixel (411) is the same as the color of light emitted from a sub-pixel (421), the width (w1) of the sub-pixel (411) may be the same as the width (w2) of the sub-pixel (421).

[0055] Another layer (402) of the display panel (160) may include an opaque member (430) (or a black matrix (430)). The opaque member (430) may be included in the other layer (402) of the display panel (160) for the first privacy display mode and the second privacy display mode. For example, the opaque member (430) may be partially overlaid on the pixel (321) and not overlaid on the pixel (311) to narrow the FOI of the light emitted from the pixel (321) to that of the light emitted from the pixel (311). For example, the opaque member (430) may partially overlap the pixel (321) among the pixels (311) and (321). For example, the opaque member (430) may be positioned above or over a portion of the PDL (441) that defines the pixel (321) and sub-pixels (e.g., sub-pixel (421) and sub-pixel (422)) within the pixel (321), and may not be positioned over another portion of the PDL (441) that defines the pixel (311) and sub-pixels (e.g., sub-pixel (411) and sub-pixel (412)) within the pixel (311). For example, the opaque member (430) may include an opening (431) (or a first light-transmitting portion (431) (or a first light-transmitting area (431)) disposed over the pixel (311) and openings (432) (or second light-transmitting portions (432)) (or second light-transmitting areas (432)) disposed over the pixel (321). The opening (431) may be aligned with the pixel (311). The opening (431) may overlap sub-pixels within the pixel (311). The opening (431) may surround the sub-pixels within the pixel (311) when the display panel (160) is viewed from above. The sub-pixels within the pixel (311) may be positioned within the opening (431) when the display panel (160) is viewed from above. The openings (432) may be aligned with the pixel (321). Each of the sub-pixels can be aligned with each other.The openings (432) may overlap with the sub-pixels within the pixel (321), respectively. The openings (432) may surround the sub-pixels within the pixel (321), respectively, when the display panel (160) is viewed from above. The sub-pixels within the pixel (321) may be respectively positioned within the openings (432), when the display panel (160) is viewed from above.

[0056] For example, the size of the aperture (431) may be larger than the size of each of the apertures (432). For example, the sub-pixels (e.g., sub-pixel (411) and sub-pixel (412)) within the pixel (311) may be positioned below the aperture (431) (or the first light-transmitting portion (431)). For example, each of the sub-pixels (e.g., sub-pixels (421) and (422)) within the pixel (321) may be positioned below each of the apertures (432) (or second light-transmitting portions (432)). The sub-pixels within the pixel (311) may be described as first sub-pixels positioned below one light-transmitting portion (e.g., first light-transmitting portion (431)) within the other layer (402), and the sub-pixels within the pixel (321) may be described as second sub-pixels positioned below other light-transmitting portions (e.g., second light-transmitting portions (432)) within the other layer (402) that are smaller than the light-transmitting portion (e.g., first light-transmitting portion (431)) within the other layer (402).

[0057] As a non-limiting example, the width (w3) of one of the apertures (432) may be equal to the width (w2) of the sub-pixel (421). As a non-limiting example, the width (w3) of one of the apertures (432) may be wider than the width (w2) of the sub-pixel (421). As a non-limiting example, the width (w3) of one of the apertures (432) may be narrower than the width (w2) of the sub-pixel (421).

[0058] As a non-limiting example, the display panel (160) may further include at least one layer disposed between the layer (401) and another layer (402).

[0059] For example, the at least one layer may include a color filter layer (not shown in FIG. 4). The color filter layer may include an opaque member (460) including opaque portions positioned between the PDL (441) and the opaque member (430). For example, the opaque member (460) included in the color filter layer of the display panel (160) may include (or define) an opening (461) (or a light-transmitting portion (461)) corresponding to the opening (431) and openings (462) (or light-transmitting portions (462)) corresponding to the openings (432), respectively. The opaque member (460) defining the opening (461) and the openings (462) may be included in the display panel (160) to guide light emitted (or transmitted) toward each of the openings (432). For example, light from a sub-pixel (421) can be emitted (or transmitted) to an opening (432) aligned with the sub-pixel (421) by the opaque member (460). For example, light from a sub-pixel (422) can be emitted (or transmitted) to an opening (432) aligned with the sub-pixel (422) by the opaque member (460). The color filter layer can be disposed over, on, or above a touch layer between the layer (401) and another layer (402). The touch layer can be used to identify a touch input on the display panel (160).

[0060] For example, the at least one layer may include a layer disposed on the color filter layer. The layer disposed on the color filter layer may include an opaque member (460) including opaque portions positioned between the PDL (441) and the opaque member (430). For example, the opaque member (460) included in the layer of the display panel (160) disposed on the color filter layer of the display panel (160) may include an opening (461) (or a light-transmitting portion (461)) corresponding to the opening (431) and openings (462) (or light-transmitting portions (462)) corresponding to the openings (432), respectively. The opaque member (460) defining the opening (461) and the openings (462) may be included in the display panel (160) to guide light emitted (or transmitted) toward each of the openings (432). For example, light from a sub-pixel (421) can be emitted (or transmitted) to an opening (432) aligned with the sub-pixel (421) by the opaque member (460). For example, light from a sub-pixel (422) can be emitted (or transmitted) to an opening (432) aligned with the sub-pixel (422) by the opaque member (460). The color filter layer can be disposed between the layer including the opaque member (460) and a touch layer. The touch layer can be used to identify a touch input on the display panel (160).

[0061] Figure 5 illustrates another configuration example of a display panel of an electronic device.

[0062] Referring to FIG. 5, the display panel (160) may include a plurality of pixels. Each of the pixels may include first pixels (510) and second pixels (520). For example, the first pixels (510) may include pixels (511) and (512). For example, the second pixels (520) may include pixels (521) and (522). As a non-limiting example, the first pixels (510) and the second pixels (520) may be alternated with each other. As a non-limiting example, the first pixels (510) and the second pixels (520) may be arranged in an interleaved arrangement.

[0063] The first pixels (510) may include sub-pixels. The sub-pixels may include a first sub-pixel (550-1) configured to emit light in a first color (e.g., red), a second sub-pixel (550-2) configured to emit light in a second color (e.g., green), and a third sub-pixel (550-3) configured to emit light in a third color (e.g., blue). The sub-pixels may further include a fourth sub-pixel (not shown) configured to emit light in a fourth color (e.g., white).

[0064] The second pixels (520) may include sub-pixels. The sub-pixels may include a first sub-pixel (560-1) configured to emit light in a first color (e.g., red), a second sub-pixel (560-2) configured to emit light in a second color (e.g., green), and a third sub-pixel (560-3) configured to emit light in a third color (e.g., blue). The sub-pixels may further include a fourth sub-pixel (not shown) configured to emit light in a fourth color (e.g., white).

[0065] Each of the sub-pixels within each of the second pixels (520) may include portions that are spaced apart from each other. For example, the first sub-pixel (560-1) may include a first portion (560-1a) of the first sub-pixel (560-1), a second portion (560-1b) of the first sub-pixel (560-1), a third portion (560-1c) of the first sub-pixel (560-1), and a fourth portion (560-1d) of the first sub-pixel (560-1). The first portion (560-1a) of the first sub-pixel (560-1), the second portion (560-1b) of the first sub-pixel (560-1), the third portion (560-1c) of the first sub-pixel (560-1), and the fourth portion (560-1d) of the first sub-pixel (560-1) may be spaced apart from each other. A first part (560-1a) of the first sub-pixel (560-1), a second part (560-1b) of the first sub-pixel (560-1), a third part (560-1c) of the first sub-pixel (560-1), and a fourth part (560-1d) of the first sub-pixel (560-1) may be described as micropixels of the first sub-pixel (560-1). For example, a second sub-pixel (560-2) may include a first part (560-2a) of the second sub-pixel (560-2), a second part (560-2b) of the second sub-pixel (560-2), a third part (560-2c) of the second sub-pixel (560-2), and a fourth part (560-2d) of the second sub-pixel (560-2). The first part (560-2a) of the second sub-pixel (560-2), the second part (560-2b) of the second sub-pixel (560-2), the third part (560-2c) of the second sub-pixel (560-2), and the fourth part (560-2d) of the second sub-pixel (560-2) may be spaced apart from each other.For example, a first part (560-2a) of the second sub-pixel (560-2), a second part (560-2b) of the second sub-pixel (560-2), a third part (560-2c) of the second sub-pixel (560-2), and a fourth part (560-2d) of the second sub-pixel (560-2) may be described as micropixels of the second sub-pixel (560-2). For example, a third sub-pixel (560-3) may include a first part (560-3a) of the third sub-pixel (560-3), a second part (560-3b) of the third sub-pixel (560-3), a third part (560-3c) of the third sub-pixel (560-3), and a fourth part (560-3d) of the third sub-pixel (560-3). A first part (560-3a) of the third sub-pixel (560-3), a second part (560-3b) of the third sub-pixel (560-3), a third part (560-3c) of the third sub-pixel (560-3), and a fourth part (560-3d) of the third sub-pixel (560-3) may be spaced apart from each other. For example, a first part (560-3a) of the third sub-pixel (560-3), a second part (560-3b) of the third sub-pixel (560-3), a third part (560-3c) of the third sub-pixel (560-3), and a fourth part (560-3d) of the third sub-pixel (560-3) may be described as micropixels of the third sub-pixel (560-3).

[0066] For example, the FOI of light emitted from the second pixels (520) may be narrower than the FOI of light emitted from the first pixels (510). For example, to narrow (or reduce) the FOI of light emitted from the second pixels (520) more than the FOI of light emitted from the first pixels (510), the layer of the display panel (160) including the pixels may include a PDL that further defines the micropixels of the first subpixel (560-1), the micropixels of the second subpixel (560-2), and the micropixels of the third subpixel (560-3). For example, in order to narrow (or reduce) the FOI of light emitted from the second pixels (520) more than the FOI of light emitted from the first pixels (510), another layer (e.g., another layer (602) of FIG. 6) of the display panel (160) disposed on the layer (e.g., layer (601) of FIG. 6) of the display panel (160) including the pixels may include an opaque member. The opaque member in the other layer of the display panel (160) may partially overly one or more of the plurality of pixels and may not overly over the other or more of the plurality of pixels. The PDL in the layer of the display panel (160) and the opaque member in the other layer of the display panel (160) may be structures for narrowing the viewing angle of at least a portion of a screen (e.g., screen (110)) displayed on the display panel (160). The opaque member disposed within the other layer of the display panel (160) according to the configuration example of FIG. 5 is described in more detail with reference to FIG. 6.

[0067] Fig. 6 is a cross-sectional view of a display panel according to an example configuration of Fig. 5.

[0068] Referring to FIG. 6, the display panel (160) may include a layer (601) and another layer (602) disposed (or positioned) on the layer (601). The layer (601) of the display panel (160) may be described as a light-emitting layer (601). The other layer (602) of the display panel (160) may be described as a masking layer (602) (or mask layer (602)) (or black matrix layer (602)).

[0069] The layer (601) of the display panel (160) may include first pixels (510) and second pixels (520). The first pixels (510) may include a pixel (511). The pixel (511) may include a sub-pixel (611) and a sub-pixel (612). The second pixels (520) may include a pixel (521). The pixel (521) may include a sub-pixel (621) and a sub-pixel (622). The sub-pixel (621) may include a first portion (621-1) of the sub-pixel (621) and a second portion (621-2) of the sub-pixel (621). The sub-pixel (622) may include a first portion (622-1) of the sub-pixel (622) and a second portion (622-2) of the sub-pixel (622).

[0070] The layer (601) of the display panel (160) may include a pixel definition layer (PDL) (641). The PDL (641) may define the periphery of a pixel (511) and the periphery of a pixel (521). The PDL (641) may define the periphery of a subpixel (611) within a pixel (511) and the periphery of a subpixel (612) within a pixel (511). The PDL (641) may define the periphery of a subpixel (621) within a pixel (521) and the periphery of a subpixel (622) within a pixel (521). The PDL (641) may further define an edge of a first portion (621-1) of the sub-pixel (621) and an edge of a second portion (621-2) of the sub-pixel (621) relative to the PDL (441) (e.g., the PDL (441) of FIG. 4). The PDL (641) may further define an edge of a first portion (622-1) of the sub-pixel (622) and an edge of a second portion (622-2) of the sub-pixel (622) relative to the PDL (441) (e.g., the PDL (441) of FIG. 4). For example, the PDL (641) may be disposed between a pixel (511) and a pixel (521), disposed between a sub-pixel (611) and a sub-pixel (612), disposed between a sub-pixel (621) and a sub-pixel (622), disposed between a first part (621-1) of a sub-pixel (621) and a second part (621-2) of a sub-pixel (621), and disposed between a first part (622-1) of a sub-pixel (622) and a second part (622-2) of a sub-pixel (622).

[0071] As a non-limiting example, the width (w1) of a sub-pixel (611) defined by a PDL (641) may be wider than the width (w2) of a first portion (621-1) of a sub-pixel (621) defined by a PDL (641) and the width (w3) of a second portion (621-2) of a sub-pixel (621) defined by a PDL (641).

[0072] Another layer (602) of the display panel (160) may include an opaque member (630) (or a black matrix (630)). The opaque member (630) may be included in the other layer (602) of the display panel (160) for the first privacy display mode and the second privacy display mode. For example, the opaque member (630) may be partially overlaid on the pixel (521) and not overlaid on the pixel (511) to narrow the FOI of the light emitted from the pixel (521) compared to the FOI of the light emitted from the pixel (511). For example, the opaque member (630) may partially overlap the pixel (521) among the pixels (511) and (521). For example, the opaque member (630) may be positioned above or over a portion of the PDL (641) that defines the pixel (521) and sub-pixels (e.g., sub-pixel (621) and sub-pixel (622)) within the pixel (521), and may not be positioned over another portion of the PDL (641) that defines the pixel (511) and sub-pixels (e.g., sub-pixel (611) and sub-pixel (612)) within the pixel (511). For example, the opaque member (630) may be further disposed over a portion of the PDL (641) defining a first portion (621-1) of the sub-pixel (621) and a second portion (621-2) of the sub-pixel (621), and a portion of the PDL (641) defining a first portion (622-1) of the sub-pixel (622) and a second portion (622-2) of the sub-pixel (622), relative to the opaque member (430) (e.g., the opaque member (430) of FIG. 4).

[0073] For example, the opaque member (630) may include an opening (631) (or a light-transmitting portion (631)) disposed over a pixel (511) and openings (632) (or light-transmitting portions (632)) disposed over a pixel (521). For example, the size of the opening (631) may be larger than the size of each of the openings (632). The sub-pixels within the pixel (511) may be described as first sub-pixels disposed under one light-transmitting portion (e.g., a first light-transmitting portion (631)) within another layer (602), and the sub-pixels within the pixel (521) may be described as second sub-pixels disposed under other light-transmitting portions (e.g., second light-transmitting portions (632)) within another layer (602) that are smaller than the light-transmitting portion (e.g., the first light-transmitting portion (631)) within the other layer (602).

[0074] As a non-limiting example, the width (w4) of one of the apertures (632) may be equal to the width (w2) of the first portion (621-1) of the sub-pixel (621) (or the width (w3) of the second portion (621-2) of the sub-pixel (621). As a non-limiting example, the width (w4) of one of the apertures (632) may be wider than the width (w2) of the first portion (621-1) of the sub-pixel (621) (or the width (w3) of the second portion (621-2) of the sub-pixel (621). As a non-limiting example, the width (w4) of one of the apertures (632) may be narrower than the width (w2) of the first portion (621-1) of the sub-pixel (621) (or the width (w3) of the second portion (621-2) of the sub-pixel (621).

[0075] Referring back to FIG. 2, the electronic device (100) may provide the first privacy display mode and the second privacy display mode to protect privacy (or user privacy) in relation to displaying a screen (e.g., screen (110)) on the display panel (160). For example, the first privacy display mode and the second privacy display mode may be described as display modes for reducing the probability that information within the screen displayed on the display panel (160) will be visible to another user who is distinct from the user of the electronic device (100). For example, the first privacy display mode and the second privacy display mode may be described as display modes for reducing the probability that information within the screen displayed on the display panel (160) will be visible from a second space around a first space in front of the display panel (160). For example, the first privacy display mode and the second privacy display mode may be described as display modes for reducing visibility from the second space.

[0076] For example, controlling at least some of the first sub-pixels and at least some of the second sub-pixels to provide the first privacy display mode and the second privacy display mode may have greater complexity than controlling at least some of the first sub-pixels to provide the first privacy display mode and the second privacy display mode. For example, the electronic device (100) may control at least some of the first sub-pixels to provide the first privacy display mode and the second privacy display mode with simplified (or reduced) operations. For example, the electronic device (100) may adjust a brightness range of light emitted from the first sub-pixels based on changing the normal display mode to the first privacy display mode. For example, the electronic device (100) may maintain a brightness range of light emitted from the second sub-pixels independently of changing the normal display mode to the first privacy display mode. For example, maintaining the brightness range of the light emitted from the second sub-pixels can be performed under a condition that the brightness setting of the display panel (160) (or the display (220)) is maintained. For example, the electronic device (100) can adjust the brightness range of the light emitted from the first sub-pixels based on changing the normal display mode to the second privacy display mode. For example, the electronic device (100) can maintain the brightness range of the light emitted from the second sub-pixels independently of changing the normal display mode to the second privacy display mode. For example, maintaining the brightness range of the light emitted from the second sub-pixels can be performed under a condition that the brightness setting of the display panel (160) (or the display (220)) is maintained.For example, the electronic device (100) can adjust the brightness range of light emitted from the first sub-pixels based on changing the first privacy display mode to the second privacy display mode. For example, the electronic device (100) can adjust the brightness range of light emitted from the first sub-pixels based on changing the first privacy display mode to the normal display mode. For example, the electronic device (100) can maintain the brightness range of light emitted from the second sub-pixels independently of changing the first privacy display mode to the normal display mode. For example, maintaining the brightness range of light emitted from the second sub-pixels can be performed under a condition that the brightness setting of the display panel (160) (or display (220)) is maintained. For example, the electronic device (100) can adjust the brightness range of light emitted from the first sub-pixels based on changing the second privacy display mode to the normal display mode. For example, the electronic device (100) can maintain the brightness range of the light emitted from the second sub-pixels independently of changing the second privacy display mode to the normal display mode. For example, maintaining the brightness range of the light emitted from the second sub-pixels can be performed under the condition that the brightness setting of the display panel (160) (or the display (220)) is maintained. For example, the electronic device (100) can adjust the brightness range of the light emitted from the first sub-pixels based on changing the second privacy display mode to the first privacy display mode. For example, the electronic device (100) can maintain the brightness range of the light emitted from the second sub-pixels independently of changing the second privacy display mode to the first privacy display mode.For example, maintaining the brightness range of light emitted from the second sub-pixels can be performed under the condition that the brightness setting of the display panel (160) (or display (220)) is maintained.

[0077] For example, the display driving circuit (221) (or DPU (212) (hereinafter, referred to as the display driving circuit (221)) can control the first sub-pixels to emit light within a first brightness range and control the second sub-pixels to emit light within the first brightness range in order to display a screen on the display panel (160) according to the normal display mode. For example, the display driving circuit (221) can control the first sub-pixels to stop emitting light and control the second sub-pixels to emit light within the first brightness range in order to display a screen on the display panel (160) according to the first privacy display mode. For example, the display driving circuit (221) can control the first sub-pixels to emit light within a second brightness range that is narrower than the first brightness range and control the second sub-pixels to emit light within the first brightness range in order to display a screen on the display panel (160) according to the second privacy display mode. There is. The highest brightness level among the brightness levels within the second brightness range may be lower than the highest brightness level among the brightness levels within the first brightness range.

[0078] For example, the display driving circuit (221) (or DPU (212) (hereinafter, described as the display driving circuit (221)) can receive an image corresponding to a screen (e.g., screen (110)) to be displayed on the display panel (160) from at least one processor (210) (or CPU (211) (hereinafter, described as at least one processor (210)). For example, the display driving circuit (221) can adjust the brightness range of light emitted from the first sub-pixels by adjusting the grayscale values ​​of a portion of the image (e.g., corresponding to a portion of the screen displayed through the first sub-pixels) associated with the first sub-pixels. For example, the display driving circuit (221) can refrain from, bypass, skip, or omit adjusting the grayscale values ​​of the image received from at least one processor (210) in order to display the screen on the display panel (160) according to the normal display mode. For example, the display driving The circuit (221) may adjust the grayscale values ​​of the part (e.g., related to the first sub-pixels) of the image received from at least one processor (210) to the lowest grayscale value (e.g., 0) in order to display a screen on the display panel (160) according to the first privacy display mode. For example, the display driving circuit (221) may adjust the grayscale range of the grayscale values ​​of the part (e.g., related to the first sub-pixels) of the image received from at least one processor (210) from a first grayscale range to a second grayscale range narrower than the first grayscale range in order to display a screen on the display panel (160) according to the second privacy display mode. A highest grayscale value among the grayscale values ​​within the second grayscale range may be lower than a highest grayscale value among the grayscale values ​​within the first grayscale range.

[0079] The operation of the display driving circuit (221) performed to display the screen on the display panel (160) according to the above normal display mode is described with reference to FIG. 7.

[0080] FIG. 7 is a chart showing the grayscale range used to control the first sub-pixels and the grayscale range used to control the second sub-pixels while activating the normal display mode.

[0081] Referring to FIG. 7, the horizontal axis of the chart (700) represents an input grayscale value, and the vertical axis of the chart (700) represents an output grayscale value. As a non-limiting example, the display driving circuit (221) (or DPU (212)) may include a processing circuit (e.g., performed on a sub-pixel basis) for narrowing a viewing angle of a screen (e.g., screen (110)) displayed on the display panel (160). For example, the processing circuit may be included in the display driving circuit (221) (or DPU (212)) for the first privacy display mode and the second privacy display mode. As a non-limiting example, the processing circuit may be included in the display driving circuit (221) (or DPU (212)) with respect to the first sub-pixels. For example, the input grayscale value may be described as a grayscale value input to the processing circuit. For example, the input grayscale value may be described as a grayscale value of an image (e.g., corresponding to the screen) before (or immediately before) being provided to the processing circuit. For example, the output grayscale value may be described as a grayscale value output from the processing circuit. For example, the output grayscale value may be described as a grayscale value obtained from the processing circuit. As a non-limiting example, the output grayscale value may correspond to a data voltage to be provided to a subpixel of the display panel (160).

[0082] For example, a line (711) in the chart (700) represents a relationship between an input grayscale value associated with the first sub-pixels and an output grayscale value associated with the first sub-pixels. For example, since the normal display mode is provided while the processing circuit is inactive or by bypassing the processing circuit, the output grayscale value may be the same as the input grayscale value. For example, the display driver circuit (210) may control the first sub-pixels using output grayscale values ​​that are each the same as the input grayscale values ​​within the grayscale range (720) for the normal display mode. For example, the output grayscale values ​​may be within a first grayscale range (710) that is the same as the grayscale range (720). For example, the display driver circuit (221) may control the first sub-pixels to emit light within a first brightness range corresponding to the first grayscale range (710) for the normal display mode.

[0083] For example, a line (712) in the chart (700) represents a relationship between an input grayscale value associated with the second sub-pixels and an output grayscale value associated with the second sub-pixels. For example, the display driver circuit (210) may control the second sub-pixels using output grayscale values ​​that are each identical to the input grayscale values ​​within a grayscale range (720) for the normal display mode. For example, the output grayscale values ​​may be within a first grayscale range (710) that is identical to the grayscale range (720). For example, the display driver circuit (221) may control the second sub-pixels to emit light within the first brightness range for the normal display mode.

[0084] The operation of the display driving circuit (221) performed to display the screen on the display panel (160) according to the above first privacy display mode is described with reference to FIG. 8.

[0085] FIG. 8 is a chart showing the grayscale range used to control the first sub-pixels and the grayscale range used to control the second sub-pixels while activating the first privacy display mode.

[0086] Referring to Fig. 8, the horizontal axis of the chart (800) represents an input grayscale value, and the vertical axis of the chart (800) represents an output grayscale value. As a non-limiting example, the display driving circuit (221) (or DPU (212)) may include a processing circuit (e.g., performed on a sub-pixel basis) (e.g., the processing circuit described with reference to Fig. 7) for narrowing the viewing angle of a screen (e.g., screen (110)) displayed on the display panel (160). For example, the input grayscale value may be described as a grayscale value input to the processing circuit. For example, the input grayscale value may be described as a grayscale value of an image (e.g., corresponding to the screen) before (or immediately before) being provided to the processing circuit. For example, the output grayscale value may be described as a grayscale value output from the processing circuit. For example, the output grayscale value may be described as a grayscale value obtained from the processing circuit. As a non-limiting example, the output grayscale value may correspond to a data voltage to be provided to a subpixel of the display panel (160).

[0087] For example, a line (811) in the chart (800) represents a relationship between an input grayscale value associated with the first sub-pixels and an output grayscale value associated with the first sub-pixels. For example, since the first privacy display mode is provided by stopping, refraining from, or deactivating emitting light through the first sub-pixels, the output grayscale value can be set to a lowest grayscale value (e.g., '0') independently of the input grayscale value. For example, the display driver circuit (210) can obtain output grayscale values, which are lowest grayscale values ​​converted from input grayscale values ​​within a grayscale range (720), using the processing circuit for the first privacy display mode, and control the first sub-pixels using the output grayscale values. For example, the display driver circuit (210) can control the first sub-pixels to stop emitting light for the first privacy display mode.

[0088] For example, line (712) in chart (800) represents a relationship between input grayscale values ​​associated with the second sub-pixels and output grayscale values ​​associated with the second sub-pixels. For example, the display driver circuit (210) can control the second sub-pixels using output grayscale values ​​that are each identical to the input grayscale values ​​within the grayscale range (720) for the first privacy display mode. For example, the output grayscale values ​​can be within a first grayscale range (710) that is identical to the grayscale range (720). For example, the display driver circuit (221) can control the second sub-pixels to emit light within the first brightness range for the first privacy display mode.

[0089] The operation of the display driving circuit (221) performed to display the screen on the display panel (160) according to the second privacy display mode is described with reference to FIG. 9.

[0090] FIG. 9 is a chart showing the grayscale range used to control the first subpixels and the grayscale range used to control the second subpixels while activating the second privacy display mode.

[0091] Referring to FIG. 9, the horizontal axis of the chart (900) represents an input grayscale value, and the vertical axis of the chart (900) represents an output grayscale value. As a non-limiting example, the display driving circuit (221) (or DPU (212)) may include a processing circuit (e.g., performed on a sub-pixel basis) (e.g., the processing circuit described with reference to FIGS. 7 and 8) for narrowing the viewing angle of a screen (e.g., screen (110)) displayed on the display panel (160). As a non-limiting example, the processing circuit may be used only for the second privacy display mode. For example, the input grayscale value may be described as a grayscale value input to the processing circuit. For example, the input grayscale value may be described as a grayscale value of an image (e.g., corresponding to the screen) before (or immediately before) being provided to the processing circuit. For example, the output grayscale value may be described as a grayscale value output from the processing circuit. For example, the output grayscale value may be described as a grayscale value obtained from the processing circuit. As a non-limiting example, the output grayscale value may correspond to a data voltage to be provided to a subpixel of the display panel (160).

[0092] For example, a line (911) in the chart (900) represents a relationship between an input grayscale value associated with the first sub-pixels and an output grayscale value associated with the first sub-pixels. For example, since the second privacy display mode is provided by adjusting (or limiting) a brightness range of light emitted through the first sub-pixels, the output grayscale value may be different from the input grayscale value. For example, the display driver circuit (210) may obtain output grayscale values ​​converted from input grayscale values ​​within a grayscale range (720) using the processing circuit for the second privacy display mode, and control the first sub-pixels using the output grayscale values. For example, a viewing angle of a screen displayed on the display panel (160) according to the second privacy display mode may be adjusted by the output grayscale values. For example, the output grayscale values ​​may be within a second grayscale range (920) that is narrower than the grayscale range (720). For example, the output grayscale values ​​may be within a second grayscale range (920) that is narrower than the first grayscale range (710). For example, the display driving circuit (221) may control the first subpixels by using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (920) that is narrower than the first grayscale range (710), thereby adjusting the viewing angle of the screen displayed within the second privacy display mode.

[0093] A change in the output grayscale value associated with the first sub-pixels may be different from a change in the output grayscale value associated with the second sub-pixels (or an input grayscale value associated with the first sub-pixels). A direction of change in the output grayscale value associated with the first sub-pixels may be opposite to a direction of change in the output grayscale value associated with the second sub-pixels (or an input grayscale value associated with the first sub-pixels). For example, the output grayscale value associated with the first sub-pixels may decrease as the output grayscale value associated with the second sub-pixels (or the input grayscale value associated with the first sub-pixels) increases.

[0094] As a non-limiting example, the output grayscale values ​​represented by lines (911) in the chart (900) may be determined according to a contrast ratio (CR) for the second privacy display mode. For example, the CR may be described as a ratio of a second brightness level of light emitted through a second sub-pixel (e.g., one of the second sub-pixels) controlled using a highest grayscale value (e.g., '255') to a first brightness level of light emitted through a first sub-pixel (e.g., one of the first sub-pixels) controlled using a lowest grayscale value (e.g., '0'). The second brightness level may be described as a brightness level of light from a light-emitting element of the second sub-pixel measured in a second space around a first space in front of the display panel (160). For example, the second brightness level may be described as a brightness level of light from a light-emitting element of the second sub-pixel measured in a direction inclined at 45 degrees with respect to the direction of the second sub-pixel (or the direction of the display area of ​​the display panel (160)). The first brightness level may be described as a brightness level of light from a light-emitting element of the first sub-pixel measured in the second space. For example, the first brightness level may be described as a brightness level of light from a light-emitting element of the first sub-pixel measured in a direction inclined at 45 degrees with respect to the direction of the first sub-pixel (or the direction of the display area of ​​the display panel (160)).

[0095] For example, when the CR is '1:1' and the second brightness level is '0.05', the first brightness level may be '0.05'. For example, when the CR is '2:1' and the second brightness level is '0.05', the first brightness level may be '0.025'.

[0096] As a non-limiting example, the output grayscale values ​​represented by the line (911) in the chart (900) may be determined using reference data (e.g., a look-up table) set in relation to the CR. For example, the reference data may be stored in a memory associated with the display driving circuit (221) (or the DPU (212)). For example, the memory associated with the display driving circuit (221) may be included in the display driving circuit (221). For example, the memory associated with the DPU (212) may be a part of the memory (230). For example, the memory associated with the display driving circuit (221) (or the DPU (212)) may be described as a storage device of the electronic device (100) that stores (or records) the reference data read by the display driving circuit (221) (or the DPU (212)).

[0097] For example, the reference data when the CR is '1:1' can be expressed as in Table 1 below.

[0098]

[0099] In Table 1, the 'brightness level (@ 0 degree)' associated with the second sub-pixel represents the brightness level (e.g., measured in the direction of the second sub-pixel (or the direction of the display area of ​​the display panel (160))) of light from the second sub-pixel controlled using the 'output grayscale value' associated with the second sub-pixel (e.g., the same as the 'input grayscale value' associated with the second sub-pixel). For example, when the 'output grayscale value' associated with the second sub-pixel is '223' and the gamma value is '2.2', the 'brightness level (@ 0 degree)' associated with the second sub-pixel is '0.745 (=(223 / 255)^(2.2))'. In Table 1, the 'brightness level (@ 45 degrees)' associated with the second sub-pixel represents the brightness level of light from the second sub-pixel (e.g., measured in a direction inclined at 45 degrees with respect to the direction of the second sub-pixel) controlled using the 'output grayscale value' associated with the second sub-pixel. As a non-limiting example, the 'brightness level (@ 45 degrees)' associated with the second sub-pixel may be 1 / 20 times the 'brightness level (@ 0 degrees)' associated with the second sub-pixel. For example, when the 'brightness level (@ 0 degrees)' associated with the second sub-pixel is '0.745', the 'brightness level (@ 45 degrees)' associated with the second sub-pixel is '0.037 (=(223 / 255)^(2.2)*(1 / 20)).

[0100] In Table 1, the 'input grayscale value' associated with the first sub-pixel represents the grayscale value input to the processing circuit.

[0101] In Table 1, the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel can be determined according to the CR. For example, the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel can be determined according to the following mathematical expression 1.

[0102]

[0103] In mathematical expression 1, a and b represent the CR as 'a:b', B2 represents the 'brightness level (@ 45 degrees)' associated with the second sub-pixel when the 'output grayscale value' associated with the second sub-pixel is '255', GI represents the input grayscale value associated with the first sub-pixel, r represents a gamma value, 255 represents the highest grayscale value, and B1 represents the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel.

[0104] 'a' represents the 'brightness level (@ 45 degrees)' associated with the second sub-pixel, 'b' represents the 'brightness level (@ 45 degrees)' associated with the first sub-pixel, and the CR of 'a:b' may represent the difference (or ratio) (or relationship) between the 'brightness level (@ 45 degrees)' associated with the second sub-pixel and the 'brightness level (@ 45 degrees)' associated with the first sub-pixel. For example, when the CR of 'a:b' is 1:1, the 'brightness level (@ 45 degrees)' associated with the second sub-pixel and the 'brightness level (@ 45 degrees)' associated with the first sub-pixel may be the same.

[0105] For example, when the CR is 1:1, the 'brightness level (@ 45 degrees)' associated with the second sub-pixel is '0.050' (e.g., the 'output grayscale value' associated with the second sub-pixel is '255'), the gamma value is '2.2', and the input grayscale value associated with the first sub-pixel is 255, B1, which is the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel, may be '0.000'. For another example, when the CR is 1:1, the 'brightness level (@ 45 degrees)' associated with the second sub-pixel is '0.050' (e.g., the 'output grayscale value' associated with the second sub-pixel is '255'), the gamma value is '2.2', and the input grayscale value associated with the first sub-pixel is 0, B1, which is the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel, may be '0.050'.

[0106] In Table 1, the 'target brightness level (@ 0 degrees)' associated with the first sub-pixel may be determined according to the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel. As a non-limiting example, the 'target brightness level (@ 0 degrees)' associated with the first sub-pixel may be 5 / 2 times the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel. For example, when the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel is determined as '0.050' according to the CR as shown in Table 1, the 'target brightness level (@ 0 degrees)' associated with the first sub-pixel is '0.125 (= (0.05) * 2.5)'.

[0107] In Table 1, the 'output grayscale value' associated with the first sub-pixel may be represented by a line (911) in the chart (900) as a value corresponding to the 'target brightness level (@ 0 degrees)'. For example, when the gamma value is '2.2' and the 'input grayscale value' associated with the first sub-pixel is '0', the 'output grayscale value' associated with the first sub-pixel is '99'. For another example, when the gamma value is '2.2' and the 'input grayscale value' associated with the first sub-pixel is '63', the 'output grayscale value' associated with the first sub-pixel is '97'.

[0108] In Table 1, the 'brightness level (@ 45 degrees)' associated with the display panel (160) represents a brightness level measured in a direction tilted 45 degrees with respect to the direction of the display panel (160) when controlling the first sub-pixel and the second sub-pixel according to Table 1 for the second privacy display mode. The 'brightness level (@ 45 degrees)' associated with the display panel (160) may correspond to a brightness level determined by adding the 'target brightness level (@ 45 degrees)' associated with the first sub-pixel to the 'brightness level (@ 45 degrees)' associated with the second sub-pixel.

[0109] In Table 1, the 'brightness level (@ 0 degree)' associated with the display panel (160) represents a brightness level measured in the direction of the display panel (160) when controlling the first sub-pixel and the second sub-pixel according to Table 1 for the second privacy display mode. The 'brightness level (@ 0 degree)' associated with the display panel (160) may correspond to a brightness level determined by adding the 'target brightness level (@ 0 degree)' associated with the first sub-pixel to the 'brightness level (@ 0 degree)' associated with the second sub-pixel.

[0110] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values ​​associated with the first sub-pixel) within a second grayscale range (920) for the second privacy display mode. For example, the display driving circuit (221) may control the first sub-pixels to emit light within a second brightness range (e.g., narrower than the first brightness range described with reference to FIGS. 7 and 8) corresponding to the second grayscale range (920) for the second privacy display mode.

[0111] For example, a line (712) in the chart (900) represents a relationship between input grayscale values ​​associated with the second sub-pixels and output grayscale values ​​associated with the second sub-pixels. For example, the display driver circuit (210) can control the second sub-pixels using output grayscale values ​​that are each identical to the input grayscale values ​​within the grayscale range (720) for the second privacy display mode.

[0112] For example, the output grayscale values ​​may be within a first grayscale range (710) that is the same as the grayscale range (720). For example, the display driver circuit (221) may control the second sub-pixels to emit light within the first brightness range (e.g., the first brightness range described with reference to FIGS. 7 and 8) for the second privacy display mode. For example, the display driver circuit (221) may maintain controlling the second sub-pixels using grayscale values ​​within the first grayscale range (710) independently of changing the first privacy display mode to the second privacy display mode or changing the normal display mode to the second privacy display mode. For example, the brightness range of light emitted using the second sub-pixels may be maintained independently of changing the first privacy display mode to the second privacy display mode or changing the normal display mode to the second privacy display mode as long as the brightness setting of the display panel (160) is maintained.

[0113] For example, within the second privacy display mode, the brightness range of light emitted through the first sub-pixels can be adjusted according to the CR. For example, within the second privacy display mode, the display driving circuit (221) can control the light emission of the second sub-pixels using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (920) determined according to the CR. For example, the second grayscale range (920) when the CR is '1:1' can be wider than the second grayscale range (920) when the CR is '4:1'. For example, the display driving circuit (221) can adjust the viewing angle of the screen displayed on the display panel (160) within the second privacy display mode using the second grayscale range (920) that changes according to the change in the CR. The second tone range (920) that changes according to the change in the above CR is explained with reference to FIG. 10.

[0114] FIG. 10 is a chart illustrating changes in the grayscale range used to control the first subpixels while activating the second privacy display mode.

[0115] Referring to FIG. 10, the display driving circuit (221) can adjust the viewing angle of the screen displayed on the display panel (160) within the second privacy display mode by converting values ​​within the reference data (e.g., expressed as in Table 1) set in relation to the reference CR (e.g., 1:1) using the reference data. The display driving circuit (221) can adjust the visibility of the side of the screen displayed on the display panel (160) (e.g., visibility from the second space) within the second privacy display mode by converting values ​​within the reference data (e.g., expressed as in Table 1) set in relation to the reference CR (e.g., 1:1) using the reference data.

[0116] The horizontal axis of the chart (1000) represents the input grayscale value related to the first sub-pixels, and the vertical axis of the chart (1000) represents the output grayscale value related to the first sub-pixels.

[0117] For example, the display driving circuit (221) can control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (1032) (e.g., the second grayscale range (920) of FIG. 9) represented by the line (911) within the chart (1000) to display the screen having the viewing angle corresponding to the reference CR.

[0118] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within a second grayscale range (1031) represented by a line (1013) within the chart (1000) to display a screen having a viewing angle corresponding to a first CR higher than the reference CR. The second grayscale range (1031) may be wider than the second grayscale range (1032).

[0119] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within a second grayscale range (1033) represented by a line (1012) within the chart (1000) to display a screen having a viewing angle corresponding to a second CR higher than the first CR. The second grayscale range (1033) may be narrower than the second grayscale range (1032).

[0120] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (1034) represented by the line (1011) within the chart (1000) to display a screen having a viewing angle corresponding to a third CR higher than the second CR. The second grayscale range (1034) may be narrower than the second grayscale range (1033).

[0121] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (1035) represented by the line (1010) within the chart (1000) to display a screen having a viewing angle corresponding to a fourth CR higher than the third CR. The second grayscale range (1035) may be narrower than the second grayscale range (1034).

[0122] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (1036) represented by the line (1014) within the chart (1000) to display a screen having a viewing angle corresponding to a fifth CR higher than the fourth CR. The second grayscale range (1036) may be narrower than the second grayscale range (1035).

[0123] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (1037) represented by the line (1015) within the chart (1000) to display a screen having a viewing angle corresponding to a sixth CR higher than the fifth CR. The second grayscale range (1037) may be narrower than the second grayscale range (1036).

[0124] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (1038) represented by the line (1016) within the chart (1000) to display a screen having a viewing angle corresponding to a seventh CR higher than the sixth CR. The second grayscale range (1038) may be narrower than the second grayscale range (1037).

[0125] For example, the display driving circuit (221) may control the first sub-pixels using grayscale values ​​(e.g., the output grayscale values) within the second grayscale range (1039) represented by the line (1017) within the chart (1000) to display a screen having a viewing angle corresponding to the eighth CR, which is higher than the seventh CR. The second grayscale range (1039) may be narrower than the second grayscale range (1038).

[0126] As a non-limiting example, the display driving circuit (221) can perform adjustment of the second grayscale range described above using the mathematical expression 2 below.

[0127]

[0128] In mathematical expression 2, D represents a difference from a reference CR, r represents a gamma value, and Gain represents a gain value applied to output grayscale values ​​related to the first sub-pixels in the reference data related to the reference CR.

[0129] For example, the display driving circuit (221) can identify (or determine) (or obtain) a second grayscale range associated with a CR changed from the reference CR by dividing each of the output grayscale values ​​associated with the first sub-pixels in the reference data by the gain value (e.g., Gain) in Equation 2.

[0130] The operations described above can be performed by the electronic device (1101) in FIG. 11.

[0131] FIG. 11 is a block diagram of an electronic device (1101) within a network environment (1100) according to various embodiments. Referring to FIG. 11, in the network environment (1100), the electronic device (1101) may communicate with the electronic device (1102) via a first network (1198) (e.g., a short-range wireless communication network), or may communicate with at least one of the electronic device (1104) or the server (1108) via a second network (1199) (e.g., a long-range wireless communication network). In one embodiment, the electronic device (1101) may communicate with the electronic device (1104) via the server (1108). According to one embodiment, the electronic device (1101) may include a processor (1120), a memory (1130), an input module (1150), an audio output module (1155), a display module (1160), an audio module (1170), a sensor module (1176), an interface (1177), a connection terminal (1178), a haptic module (1179), a camera module (1180), a power management module (1188), a battery (1189), a communication module (1190), a subscriber identification module (1196), or an antenna module (1197). In some embodiments, the electronic device (1101) may omit at least one of these components (e.g., the connection terminal (1178)), or may have one or more other components added. In some embodiments, some of these components (e.g., sensor module (1176), camera module (1180), or antenna module (1197)) may be integrated into a single component (e.g., display module (1160)).

[0132] The processor (1120) may, for example, execute software (e.g., a program (1140)) to control at least one other component (e.g., a hardware or software component) of the electronic device (1101) connected to the processor (1120) and perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (1120) may store commands or data received from other components (e.g., a sensor module (1176) or a communication module (1190)) in a volatile memory (1132), process the commands or data stored in the volatile memory (1132), and store result data in a non-volatile memory (1134).

According to one embodiment, all or part of the operations executed in the electronic device (1101) may be executed in one or more of the external electronic devices (1102, 1104, or 1108).

[0153] FIG. 12 is a block diagram (1200) of a display module (1160) according to various embodiments. Referring to FIG. 12, the display module (1160) may include a display (1210) and a display driver IC (DDI) (1230) for controlling the display (1210). The DDI (1230) may include an interface module (1231), a memory (1233) (e.g., a buffer memory), an image processing module (1235), or a mapping module (1237). The DDI (1230) may receive, for example, image information including image data or an image control signal corresponding to a command for controlling the image data, from another component of the electronic device (1101) through the interface module (1231). For example, according to one embodiment, image information may be received from a processor (1120) (e.g., a main processor (1121) (e.g., an application processor) or an auxiliary processor (1123) (e.g., a graphics processing unit) that operates independently of the function of the main processor (1121). The DDI (1230) may communicate with a touch circuit (1250) or a sensor module (1176) through the interface module (1231). In addition, the DDI (1230) may store at least a part of the received image information in the memory (1233), for example, in units of frames. The image processing module (1235) may, for example, perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least a part of the image data based on at least a characteristic of the image data or a characteristic of the display (1210). The mapping module (1237) may output a voltage value or a value corresponding to the image data preprocessed or postprocessed through the image processing module (1235). Current values ​​can be generated.According to one embodiment, the generation of voltage values ​​or current values ​​may be performed at least in part based on, for example, properties of pixels of the display (1210) (e.g., arrangement of pixels (RGB stripe or pentile structure), or size of each sub-pixel). At least some pixels of the display (1210) may be driven at least in part based on, for example, the voltage values ​​or current values, so that visual information (e.g., text, images, or icons) corresponding to the image data may be displayed through the display (1210).

[0154] According to one embodiment, the display module (1160) may further include a touch circuit (1250). The touch circuit (1250) may include a touch sensor (1251) and a touch sensor IC (1253) for controlling the touch sensor (1251). The touch sensor IC (1253) may control the touch sensor (1251) to detect, for example, a touch input or a hovering input for a specific location of the display (1210). For example, the touch sensor IC (1253) may detect the touch input or the hovering input by measuring a change in a signal (e.g., voltage, light quantity, resistance, or charge quantity) for a specific location of the display (1210). The touch sensor IC (1253) may provide information (e.g., location, area, pressure, or time) regarding the detected touch input or hovering input to the processor (1120). According to one embodiment, at least a portion of the touch circuit (1250) (e.g., touch sensor IC (1253)) may be included as part of the display driver IC (1230), or as part of the display (1210), or as part of another component (e.g., auxiliary processor (1123)) disposed external to the display module (1160).

[0155] According to one embodiment, the display module (1160) may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illuminance sensor) of the sensor module (1176), or a control circuit therefor. In this case, the at least one sensor or the control circuit therefor may be embedded in a part of the display module (1160) (e.g., the display (1210) or the DDI (1230)) or a part of the touch circuit (1250). For example, when the sensor module (1176) embedded in the display module (1160) includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) associated with a touch input through a part of the display (1210). For another example, if the sensor module (1176) embedded in the display module (1160) includes a pressure sensor, the pressure sensor may obtain pressure information associated with a touch input through a portion or the entire area of ​​the display (1210). According to one embodiment, the touch sensor (1251) or the sensor module (1176) may be disposed between pixels of a pixel layer of the display (1210), or above or below the pixel layer.

[0156] Some of the operations described above may be executed (or performed) by an artificial intelligence (AI) system as described with reference to FIG. 13. For example, the AI ​​system may be used to adjust a viewing angle provided according to the second privacy display mode based on one or more contents provided by a screen displayed on the display panel (160), the illuminance around the electronic device (100) (e.g., identified by an illuminance sensor (not shown) of the electronic device (100), the luminance of the screen displayed on the display panel (160), and / or the posture of the electronic device (100) (e.g., identified by an inertial sensor of the electronic device (100). For example, the AI ​​system may be used to adjust the second grayscale range.

[0157] Figure 13 is a schematic diagram of an exemplary AI system.

[0158] Referring to FIG. 13, the AI ​​system (1300) may include an input / output interface (1310), an AI (artificial intelligence) framework (1320), a generative AI model (1330), an application / service component (1380), and / or a knowledge repository (1390).

[0159] The input / output interface (1310) can receive input. The input can include user input and / or data acquired or generated by an electronic device (e.g., the electronic device (100) or the electronic device (1101) described above). The data can include images, videos, and / or sensor data generated by at least one processor (e.g., at least one processor (210) or processor (1120)) of the electronic device (e.g., illuminance data around the electronic device acquired from a sensor or sensor hub (e.g., a coprocessor (1123), posture data (or orientation data) of the electronic device, temperature inside the electronic device (e.g., temperature of the display (220) or temperature of the at least one processor (210)), size information of a display area of ​​the display (220), and / or images acquired through an image sensor (e.g., included in a camera module (1180)) of the electronic device). The user input may include natural language, touch data obtained through touch circuitry included within the display panel (160) (e.g., used to identify input from a finger and / or a stylus), images displayed (and / or to be displayed) on the display panel (160), and / or video. As a non-limiting example, the user input may be received by the input / output interface (1310) together with context information. The context information may be described as additional information obtained in relation to the user input. The context information may relate to a state when the user input is received (e.g., including a state of the electronic device and / or a state surrounding the electronic device (e.g., a user state)). For example, the context information may include information about one or more software applications running within the electronic device when the user input is received.For example, the contextual information may include information about the location of the electronic device (or the location of the user of the electronic device) at the time the user input is received. For example, the user input may be integrated with the contextual information. For example, the user input integrated with the contextual information may be received by the input / output interface (1310).

[0160] The input / output interface (1310) can transmit (or provide) output. The output may include a result (or result information) generated or acquired by the AI ​​system (1300) based at least in part on the input. The format of the output may vary. For example, the output may include natural language. For example, the output may include content (e.g., including media content and / or multimedia content). For example, the output may include an action related to a user of the electronic device. For example, the output may have a format according to a user setting of the electronic device.

[0161] The input / output interface (1310) can be described as a user query / response interface (1310).

[0162] The AI ​​framework (1320) can be used to obtain information (or data) about the input from the input / output interface (1310) and control one or more components related to the AI ​​system (1300) using the obtained information.

[0163] For example, the prompt design component (1321) within the AI ​​framework (1320) can use the acquired information to generate or obtain a prompt for a generative AI model (1330) (e.g., including a large language model (LLM) or a large multimodal model (LMM)). For example, the prompt design component (1321) can be described as an AI component that uses a learning algorithm and / or a neural network to provide enhanced prompts over time. For example, the prompt design component (1321) can use the acquired information to access a knowledge component (e.g., a knowledge repository (1390)) that includes user preference data, a prompt library, and / or prompt examples to generate or obtain a prompt. The generated prompt can be provided to the generative AI model (1330) (e.g., including an LLM or LMM).

[0164] For example, the API / plugin management component (1322) within the AI ​​framework (1320) may be utilized to support communication for additional information requested (or induced) in connection with the prompt provided (or to be provided) to the generative AI model (1330). For example, the API / plugin management component (1322) may be utilized to create or establish channels for communication with various data sources (e.g., knowledge repositories (1390)). For example, the API / plugin management component (1322) may support access to at least some of the data sources. For example, the API / plugin management component (1322) may be utilized to request another component (e.g., an application / service component (1380)) to perform feedback (or response) according to the prompt. As a non-limiting example, information obtained (or generated) through the API / plugin management component (1322) may be provided to the prompt design component (1321) for the purpose of generating a prompt. As a non-limiting example, information obtained (or generated) through the API / plugin management component (1322) may be provided to the generative AI model (1330).

[0165] For example, the improvement component (1323) within the AI ​​framework (1320) can at least partially tune (or adjust) (or change) the result (e.g., content) obtained (or output) from the generative AI model (1330). For example, the improvement component (1323) can determine or verify whether the content obtained from the generative AI model (1330) is related to the input. For example, the improvement component (1323) can determine or verify whether the content obtained from the generative AI model (1330) contains biased content. For example, the improvement component (1323) can determine or verify whether the content obtained from the generative AI model (1330) contains harmful content. For example, the improvement component (1323) can support or assist in performing additional processing to improve the content obtained from the generative AI model (1330). For example, the improvement component (1323) may support providing hints to the user to improve the content.

[0166] A generative AI model (1330) can be described as an artificial intelligence neural network that generates feedback in response to a prompt. For example, the feedback may include additional data and / or information related to the prompt, but relative to the prompt. For example, the feedback may include new content related to the prompt. For example, the generative AI model (1330) may include a model that generates images and / or a model that generates language. For example, the model that generates images may include a generative adversarial network (GAN) and / or a variational autoencoder (VAE). For example, the model that generates images may include a diffusion-based generative model (e.g., a transformer VAE). For example, the model that generates language may include CHAT-GPT 3 and / or CHAT-GPT 4. For example, a generative AI model (1330) may include an LMM that generates the feedback by recognizing text, images, and / or speech.

[0167] As a non-limiting example, the AI ​​framework (1320) and / or the generative AI model (1330) may be included within an AI module (e.g., including a processing circuit) within the electronic device. For example, the AI ​​module may be operatively coupled with at least one processor of the electronic device (e.g., at least one processor (210) or processor (1120)). For example, the AI ​​module may be operatively coupled with a display driving circuit of the electronic device (e.g., a display driving circuit (221) or a DDI (1230)). For example, the AI ​​module may be operatively coupled with a sensor hub of the electronic device for one or more sensors within the electronic device.

[0168] The technical problems to be achieved in the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person having ordinary knowledge in the technical field to which the present disclosure pertains.

[0169] As described above, an electronic device (e.g., electronic device (100)) may include a display panel (e.g., display panel (160)) and a display driving circuit (e.g., display driving circuit (221)). The display panel may include a first layer including first light-transmitting portions (e.g., light-transmitting portions (461)) and second light-transmitting portions (e.g., light-transmitting portions (462)) smaller than the first light-transmitting portions, and a second layer disposed under the first layer, the second layer including first sub-pixels disposed under each of the first light-transmitting portions and second sub-pixels disposed under each of the second light-transmitting portions. The display driving circuit may be configured to display a screen having a first viewing angle through the display panel by controlling the light emission of the first sub-pixels using the light emission values ​​within a first light emission range and controlling the light emission of the second sub-pixels using the light emission values ​​within the first light emission range, and to display a screen having a second viewing angle narrower than the first viewing angle through the display panel by controlling the light emission of the first sub-pixels using the light emission values ​​within a second light emission range narrower than the first light emission range and controlling the light emission of the second sub-pixels using the light emission values ​​within the first light emission range.

[0170] For example, the first layer may include black matrix portions defining the second light-transmitting portions. Light emitted from the second sub-pixels may be partially blocked by portions of the black matrix portions.

[0171] For example, the highest tone value of the second tone range may be lower than the highest tone value of the first tone range.

[0172] For example, when the screen having the first viewing angle and the screen having the second viewing angle are the same, and the brightness setting for the screen having the first viewing angle and the brightness setting for the screen having the second viewing angle are the same, the brightness level provided by the first sub-pixels to display the screen having the first viewing angle may be higher than the brightness level provided by the first sub-pixels to display the screen having the second viewing angle. For example, when the screen having the first viewing angle and the screen having the second viewing angle are the same, and the brightness setting for the screen having the first viewing angle and the brightness setting for the screen having the second viewing angle are the same, the brightness level provided by the second sub-pixels to display the screen having the first viewing angle may be the same as the brightness level provided by the second sub-pixels to display the screen having the second viewing angle.

[0173] For example, the display driving circuit may be configured to change, based on changing the display of the screen having the second viewing angle to displaying the screen having a third viewing angle different from the second viewing angle, control the emission of the first sub-pixels using the grayscale values ​​within the second grayscale range to control the emission of the first sub-pixels using the grayscale values ​​within a third grayscale range narrower than the second grayscale range, and maintain the control of the emission of the second sub-pixels using the grayscale values ​​within the first grayscale range.

[0174] For example, the second viewing angle may be wider than the critical viewing angle. For example, the display driving circuit may be configured to display a screen having the critical viewing angle through the display panel by stopping the emission of the first sub-pixels and controlling the emission of the second sub-pixels using the grayscale values ​​within the first grayscale range.

[0175] For example, the display driving circuit may be configured to control the light emission of the first sub-pixels using the grayscale values ​​within the first grayscale range for a first mode providing the first viewing angle wider than the first critical viewing angle, and to control the light emission of the second sub-pixels using the grayscale values ​​within the first grayscale range, and to control the light emission of the first sub-pixels using the grayscale values ​​within the first grayscale range for a second mode providing the second viewing angle narrower than the first critical viewing angle and wider than the second critical viewing angle, and to control the light emission of the second sub-pixels using the grayscale values ​​within the first grayscale range.

[0176] For example, the display driving circuit may be configured to refrain from emitting light from the first sub-pixels and control the emission of the second sub-pixels using grayscale values ​​within the first grayscale range for a third mode that provides the second critical viewing angle.

[0177] As described above, an electronic device (e.g., electronic device (100)) may include a display panel (e.g., display panel (160)) and a display driving circuit (e.g., display driving circuit (221)). The display panel may include a first layer including first light-transmitting portions and second light-transmitting portions smaller than the first light-transmitting portions, and a second layer disposed under the first layer, the second layer including first sub-pixels disposed under each of the first light-transmitting portions and second sub-pixels disposed under each of the second light-transmitting portions. The display driving circuit may be configured to display a screen having a first viewing angle through the display panel by controlling the first sub-pixels to emit light within a first brightness range and controlling the second sub-pixels to emit light within the first brightness range, and to display a screen having a second viewing angle narrower than the first viewing angle through the display panel by controlling the first sub-pixels to emit light within a second brightness range narrower than the first brightness range and controlling the second sub-pixels to emit light within the first brightness range.

[0178] For example, the first layer may include black matrix portions defining the second light-transmitting portions. Light emitted from the second sub-pixels may be partially blocked by portions of the black matrix portions.

[0179] For example, the highest brightness level of the second brightness range may be lower than the highest brightness level of the first brightness range. For example, when the screen having the first viewing angle and the screen having the second viewing angle are the same, and the brightness setting for the screen having the first viewing angle and the brightness setting for the screen having the second viewing angle are the same, the brightness level provided by the first sub-pixels to display the screen having the first viewing angle may be higher than the brightness level provided by the first sub-pixels to display the screen having the second viewing angle. For example, when the screen having the first viewing angle and the screen having the second viewing angle are the same, and the brightness setting for the screen having the first viewing angle and the brightness setting for the screen having the second viewing angle are the same, the brightness level provided by the second sub-pixels to display the screen having the first viewing angle may be the same as the brightness level provided by the second sub-pixels to display the screen having the second viewing angle.

[0180] For example, the display driving circuit may be configured to change, based on changing the display of the screen having the second viewing angle to displaying the screen having a third viewing angle different from the second viewing angle, control the first sub-pixels to emit light within the second brightness range to control the first sub-pixels to emit light within a third brightness range narrower than the second brightness range, and maintain the control of the second sub-pixels to emit light within the first brightness range.

[0181] For example, the second viewing angle may be wider than the critical viewing angle. For example, the display driving circuit may be configured to display a screen having the critical viewing angle through the display panel by controlling the first sub-pixels to stop emitting light and controlling the second sub-pixels to emit light within the first brightness range.

[0182] For example, the display driving circuit may be configured to control the first sub-pixels to emit light within the first brightness range and to control the second sub-pixels to emit light within the first brightness range for a first mode that provides the first viewing angle wider than the first threshold viewing angle, and to control the first sub-pixels to emit light within the first brightness range for a second mode that provides the second viewing angle narrower than the first threshold viewing angle and wider than the second threshold viewing angle, and to control the first sub-pixels to emit light within the second brightness range and to control the second sub-pixels to emit light within the first brightness range.

[0183] For example, the display driving circuit may be configured to control the first sub-pixels to refrain from emitting light for a third mode that provides the second critical viewing angle, and to control the second sub-pixels to emit light within the first brightness range.

[0184] As described above, an electronic device (e.g., electronic device (100)) may include a display panel (e.g., display panel (160)) and a display driving circuit (e.g., display driving circuit (221)). The display panel may include a first layer including first light-transmitting portions and second light-transmitting portions smaller than the first light-transmitting portions, and a second layer disposed under the first layer, the second layer including first sub-pixels disposed under each of the first light-transmitting portions and second sub-pixels disposed under each of the second light-transmitting portions. The display driving circuit may be configured to display a screen on the display panel by emitting light through the first sub-pixels and emitting light through the second sub-pixels based on a normal display mode, and to stop emitting light through the first sub-pixels based on changing the normal display mode to a first privacy display mode while the screen is maintained on the display panel, and to narrow a brightness range of light emitted through the first sub-pixels based on changing the normal display mode to a second privacy display mode while the screen is maintained on the display panel.

[0185] For example, the display driving circuit may be configured to maintain emitting light through the second sub-pixels independently of changing the normal display mode to the first privacy display mode while the screen is maintained on the display panel.

[0186] For example, the display driving circuit may be configured to maintain a brightness range of light emitted through the second sub-pixels independently of changing the normal display mode to the second privacy display mode while the screen is maintained on the display panel.

[0187] For example, the electronic device may include at least one processor (e.g., at least one processor 210) including a processing circuit, and a memory (e.g., memory 230) including one or more storage media and storing instructions. For example, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to transmit, to the display driving circuit, at least one first command indicating the first privacy display mode, and to transmit, to the display driving circuit, at least one second command indicating the second privacy display mode. For example, the display driving circuit may be configured to change the normal display mode to the first privacy display mode while the screen is maintained on the display panel based on the at least one first command received from the at least one processor, and to change the normal display mode to the second privacy display mode while the screen is maintained on the display panel based on the at least one second command received from the at least one processor.

[0188] For example, the electronic device may include at least one processor (e.g., at least one processor (210)) including a processing circuit, and a memory (e.g., memory (230)) including one or more storage media and storing instructions. For example, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to transmit an image to the display driver circuit for displaying the screen on the display panel. For example, the display driver circuit may be configured to receive the image from the at least one processor, and to narrow a brightness range of light emitted through the first sub-pixels by changing grayscale values ​​within a first grayscale range of a portion of the image corresponding to a portion of the screen displayed through the first sub-pixels to grayscale values ​​within a second grayscale range narrower than the first grayscale range based on changing the normal display mode to the second privacy display mode while the screen is maintained on the display panel.

[0189] For example, the display driving circuit may be configured to maintain grayscale values ​​within the first grayscale range of another portion of the image corresponding to another portion of the screen displayed through the second sub-pixels independently from changing the normal display mode to the second privacy display mode while the screen is maintained on the display panel.
