[0025] FIG. 1 illustrates an example of changing the viewing angle of a screen displayed on a display panel.

[0026] Referring to FIG. 1, an electronic device (101) may display a screen (110) on a display panel (160). 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. The electronic device (101) of FIG. 1 may be an example of the electronic device (1001) of FIG. 10.

[0027] For example, the electronic device (101) may have various form factors, such as a smartphone, a laptop personal computer (PC), a tablet PC, a head-mounted display (HMD) device, a watch, and other computing devices. The electronic device (101) may be referred to as a mobile device, a user terminal, a user equipment (UE), a multi-function device, a portable communication device, and / or a portable device. The form factor of the electronic device (101) is not limited to the exemplary form factor illustrated in FIG. 1 (e.g., an electronic device including a bar-type display panel (160). In one example, the electronic device (101) may be a device including a display panel (160) that is a flexible display. For example, the electronic device (101) may be referred to as a foldable electronic device, a rollable electronic device, or a multi-foldable electronic device. Specific details related to this may be referenced in FIGS. 12 to 14 below.

[0028] A display driving circuit (e.g., the display driving circuit (221) of FIG. 2 or the display driver IC (1130) of FIG. 11) can display a screen (110) having a viewing angle (181) on a display panel (160). The display panel (160) may be an example of the display panel (1160) of FIG. 11.

[0029] For example, the viewing angle (181) of the screen (110) may be wider than the viewing angle (182) of the screen (110) and the viewing angle (183) of the screen (110) described below. For example, the screen (110) having the viewing angle (181) may be displayed on the display panel (160) according to a normal display mode. For example, the viewing angle (181) may be wider than a first critical viewing angle and wider than a second critical viewing angle that is wider than the first critical viewing angle.

[0030] The electronic device (101) may provide a function (or feature) for user privacy with respect to the display on the display panel (160). For example, the electronic device (101) 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. For example, the above function may be referred to as a privacy filter function, a privacy filter mode, a privacy display function, or a privacy feature.

[0031] For example, the display panel (160) may include a display area (or active area) used for displaying a screen. The field of illumination (FOI) of light emitted from a portion of the display area may be different from the FOI of light emitted from another portion of the display area. The display panel (160) may provide one or more display modes (or a privacy filter function) by using different FOIs depending on the display area.

[0032] For example, as described below, the display panel (160) may include a first layer including an opaque member (or black matrix) (or opaque material) that includes first light-transmitting portions and second light-transmitting portions smaller than the first light-transmitting portions. For example, the opaque member (or black matrix) may define the first light-transmitting portions and the second light-transmitting portions. For example, the opaque member of the first layer may include BM (black matrix) portions such that light emitted from the second sub-pixels is partially blocked by some of the BM portions defining the second light-transmitting portions. The display panel (160) may include a second layer disposed below the first layer, the second layer including light-emitting elements (or light-emitting portions) disposed below each of the first light-transmitting portions, and light-emitting elements (or light-emitting portions) disposed below each of the second light-transmitting portions.

[0033] For example, the display panel (160) may include a first pixel comprising light-emitting elements within the second layer disposed below each of the first light-transmitting portions. For example, the first pixel may include subpixels (or first subpixels). The subpixels within the first pixel may each include the light-emitting elements within the first pixel disposed below each of the first light-transmitting portions. Each of the subpixels within the first pixel may include transistors configured to control the light-emitting elements included within each of the subpixels within the first pixel. For example, the subpixels within the first pixel may be aligned with each of the first light-transmitting portions. For example, the subpixels within the first pixel may be located within each of the first light-transmitting portions when viewed on the display panel (160). For example, the subpixels within the first pixel may overlap with each of the first light-transmitting portions. For example, each of the first light-transmitting portions may overly the subpixels within the first pixel.

[0034] For example, the display panel (160) may include second pixels including light-emitting elements within the second layer, each disposed below the second light-transmitting portions. The second pixels may be included within the display panel (160) for the privacy display mode. For example, the second pixels may include sub-pixels (or second sub-pixels). The sub-pixels within the second pixel may each include the light-emitting elements within the second pixel, each disposed below the second light-transmitting portions. Each of the sub-pixels within the second pixel may include transistors configured to control the light-emitting elements included within each of the sub-pixels within the second pixel. For example, the sub-pixels within the second pixel may be aligned with each of the second light-transmitting portions. For example, the sub-pixels within the second pixel may be positioned within each of the second light-transmitting portions when viewed on the display panel (160). For example, the sub-pixels within the second pixel may overlap each of the second light-transmitting portions. For example, each of the second light-transmitting portions may overly the sub-pixels within the second pixel.

[0035] For example, since the second light-transmitting portions are smaller than the first light-transmitting portions, the FOI of light emitted through the second pixel may be narrower than the FOI of light emitted through the first pixel.

[0036] The one or more display modes may include a first privacy display mode. For example, the electronic device (101) may display a screen (110) having a viewing angle (182), which 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 (101) may change the display of the screen (110) having a viewing angle (181) to the display of the screen (110) having a viewing angle (182), based on the first privacy display mode changed from the normal display mode. For example, the electronic device (101) can stop (or end) (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 (101) can 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 (101) can stop (or end) (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 (101) can change displaying a screen (110) having a viewing angle (182) to displaying 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 critical viewing angle may be described as the narrowest viewing angle that can be provided through the display panel (160).

[0037] The one or more display modes may include a second privacy display mode. For example, the electronic device (101) may display, on the display panel (160), 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, according to the second privacy display mode. 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 the screen displayed on the display panel (160) between the first threshold viewing angle and the second threshold viewing angle. For example, the electronic device (101) may 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 (101) can stop (or end) (or deactivate) displaying a screen (110) having a viewing angle (181) and display a screen (110) having a viewing angle (183) based on changing the normal display mode to the second privacy display mode. For example, the electronic device (101) can change displaying a screen (110) having a viewing angle (182) to displaying a screen (110) having a viewing angle (183) based on the second privacy display mode changed from the first privacy display mode. For example, the electronic device (101) can stop (or end) (or deactivate) displaying a screen (110) having a viewing angle (182) and display a screen (110) having a viewing angle (183) based on changing the first privacy display mode to the second privacy display mode.For example, the electronic device (101) can change the display of a screen (110) having a viewing angle (183) to a screen (110) having a viewing angle (181) based on changing the second privacy display mode to the normal display mode.

[0038] As a non-limiting example, the electronic device (101) may control the display panel (160) to emit light through a plurality of first pixels of the display panel (160) and emit light through a plurality of second pixels of the display panel (160) in order to perform (or execute) a display on the display panel (160) according to the normal display mode. As a non-limiting example, the electronic device (101) may control the display panel (160) to refrain from emitting light through a plurality of first pixels of the display panel (160) and to emit light through a plurality of second pixels of the display panel (160) in order to perform (or execute) a display on the display panel (160) according to the first privacy display mode. As a non-limiting example, the electronic device (101) may control the display panel (160) to emit light through some of the first pixels of the plurality of first pixels of the display panel (160) and to emit light through the plurality of second pixels of the display panel (160) in order to perform (or execute) a display on the display panel (160) according to the second privacy display mode. For example, the second pixels may be used for all of the normal display mode, the first privacy display mode, and the second privacy display mode in relation to the first pixels used for the normal display mode.

[0039] 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 (101) for user privacy, and the single privacy display mode may be described as a mode that activates a function of the electronic device (101) for user privacy. For example, the electronic device (101) 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, depending on the single privacy display mode.

[0040] Figure 2 is a schematic view of an exemplary electronic device.

[0041] Referring to FIG. 2, the electronic device (101) may include at least one processor (210) including a processing circuit, a display (220), and a memory (230). The electronic device (101) may include at least a part of the electronic device (1001) of FIG. 10 or correspond to at least a part of the electronic device (1001) of FIG. 10.

[0042] At least one processor (210) may include at least a portion of the processor (1020) of FIG. 10 or may correspond to at least a portion of the processor (1020) of FIG. 10. 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).

[0043] As a non-limiting example, at least one processor (210) may perform at least some of the operations described below using a trained model (215) (e.g., a generative artificial intelligence (AI) model (1530) of FIG. 15 ). For example, at least one processor (210) may determine, using the trained model (215), to change the normal display mode to a privacy display mode (e.g., a first privacy display mode or a second privacy display mode), and / or to change the privacy display mode to the normal display mode. For example, at least one processor (210) may determine, using the trained model (215), to change from the normal display mode to the privacy display mode by analyzing an image (or color data of the image) to be displayed on a screen if content within the image is content that should be displayed in a limited manner.

[0044] As a non-limiting example, at least one processor (210) may adjust the strength of a privacy filter executed within the privacy display mode by analyzing an image (or color data of the image) to be displayed on the screen using a trained model (215). For example, the strength of the privacy filter may be determined based on a light emission ratio of pixels with a wide viewing angle (e.g., pixels (311) of FIG. 3) within the privacy display mode. For example, the light emission ratio may represent a ratio of pixels that light up among the pixels with a wide viewing angle included in the display panel (160).

[0045] As a non-limiting example, at least one processor (210) may provide sensing data acquired using at least one sensor (not shown) of the electronic device (101) to the trained model (215). For example, the at least one sensor may include an acceleration sensor, a position sensor (e.g., GPS), an illuminance sensor, a geomagnetic sensor, or a pressure sensor. In the example, the sensing data may further include data acquired using the at least one sensor, as well as the intensity of a signal (or a radio frequency (RF) signal) received through an antenna of the electronic device (101), or data acquired using a microphone. For example, the at least one processor (210) may analyze the sensing data using the trained model (215), thereby outputting a result indicating a state of a user of the electronic device (101). For example, the state may include whether the user is moving. For example, at least one processor (210) can use the above result to determine whether to change the normal display mode to the privacy display mode and / or change the privacy display mode to the normal display mode.

[0046] As a non-limiting example, at least one processor (210) can determine a correction value for adjusting the color data to be displayed at each pixel of the display panel (160) (e.g., pixel (311) or pixel (321) of FIG. 3) by analyzing the image (or color data of the image) to be displayed on the screen using a trained model (215). For example, at least one processor (210) can transmit the correction value output from the trained model (215) to the display driving circuit (221).

[0047] As a non-limiting example, at least one processor (210) may transmit at least one first command indicating the privacy display mode to the display driving circuit (221) based on a decision to change the normal display mode to the privacy display mode (e.g., the first privacy display mode or the second privacy display mode). For example, the display driving circuit (221) may change the normal display mode to the privacy display mode based on the at least one first command. As a non-limiting example, at least one processor (210) may transmit at least one second command indicating the normal display mode to the display driving circuit (221) based on a decision to change the privacy display mode to the normal display mode. For example, the display driving circuit (221) may change the privacy display mode to the normal display mode based on the at least one second command.

[0048] The display (220) may include at least a part of the display module (1060) of FIG. 10 or correspond to at least a part of the display module (1060) of FIG. 10. The display (220) may include a display driver circuitry (display driver integrated circuitry) (221) and a display panel (160). The display driver circuitry (221) may include at least a part of the display driver IC (1130) of FIG. 11 or correspond to at least a part of the display driver IC (1130) of FIG. 11. As an example without limitation, the display driver circuitry (221) may perform at least some of the operations described below using a trained model (e.g., the generative AI (artificial intelligence) model (1530) of FIG. 15). The display panel (160) may include at least a part of the display panel (1110) of FIG. 11 or correspond to at least a part of the display panel (1110) of FIG. 11.

[0049] The display (220) may be operated or driven for the command mode, video mode, hybrid video mode, and / or ARP (adaptive refresh panel) of the MIPI (mobile industry processor interface) DSI (display serial interface).

[0050] 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 ROM (read-only memory), semi-permanent memory such as RAM (random access memory), 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 a function or feature of the electronic device (101). The memory (230) may be fixedly embedded in the electronic device (101) or incorporated into one or more suitable types of components (e.g., a SIM (subscriber identity module) card and / or an SD (secure digital) memory card) that can be repeatedly inserted into and removed from the electronic device (101). For example, the memory (230) may include at least a portion of the memory (1030) of FIG. 10 or correspond to at least a portion of the memory (1030) of FIG. 10.

[0051] 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 communication 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 part of at least one processor (210).

[0052] 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.

[0053] Figure 3 illustrates an example configuration of a display panel of an electronic device.

[0054] Referring to FIG. 3, the display panel (160) may include a plurality of pixels. For example, the display panel (160) may include first pixels (310) and second pixels (320). For example, the first pixels (310) may include pixels (311) and pixels (312). For example, the second pixels (320) may include pixels (321) and pixels (322). As an example without limitation, the first pixels (310) and the second pixels (320) may alternate with each other. As an example without limitation, the first pixels (310) and the second pixels (320) may be arranged in an interleaved arrangement.

[0055] Each of the pixels may include subpixels. The subpixels may include a first subpixel (350-1) configured to emit light in a first color (e.g., red), a second subpixel (350-2) configured to emit light in a second color (e.g., green), and a third subpixel (350-3) configured to emit light in a third color (e.g., blue). The subpixels may further include a fourth subpixel (not shown) configured to emit light in a fourth color (e.g., white).

[0056] The field of illumination (FOI) of light emitted from one or more of the pixels may be wider than the field of illumination (FOI) of light emitted from one or more of the other pixels. For example, the one or more of the pixels may include pixel (311) and pixel (312). For example, the other or more of the pixels may include pixel (321) and pixel (322).

[0057] The display panel (160) may include an opaque member in another layer of the display panel (160) (e.g., another layer (402) of FIG. 4) disposed on a layer of the display panel (160) containing the pixels (e.g., layer (401) of FIG. 4) in order to narrow (or reduce) the FOI of light emitted from one or more other pixels of the pixels compared to the FOI of light emitted from one or more of the plurality of pixels. The opaque member in the other layer of the display panel (160) may be a structure 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 in the other layer of the display panel (160) may partially overlye over one or more of the pixels and not overlye over the other 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.

[0058] FIG. 4 is a cross-sectional view of a display panel according to one configuration example of FIG. 3.

[0059] Referring to FIG. 4, the display panel (160) may include a layer (401) and another layer (402) placed (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)).

[0060] A layer (401) of a display panel (160) may include a pixel (311) located within an area (491) and a pixel (321) located within an area (492). 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).

[0061] A layer (401) of a display panel (160) may include a pixel definition layer (PDL) (441). The PDL (441) may define the periphery of a pixel (311) and the periphery of a pixel (321). The PDL (441) may define the periphery of a subpixel (411) within a pixel (311) and the periphery of a subpixel (412) within a pixel (311). The PDL (441) may define the periphery of a subpixel (421) within a pixel (321) and the periphery of a subpixel (422) within a pixel (321). For example, the PDL (441) may be placed between a pixel (311) and a pixel (321), between a subpixel (411) and a subpixel (412), and between a subpixel (421) and a subpixel (422).

[0062] 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).

[0063] 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 within the other layer (402) of the display panel (160) for the privacy display mode. For example, the opaque member (430) may be partially laid across the pixel (321) and not laid across the pixel (311) in order to narrow the FOI of light emitted from the pixel (321) compared to the FOI of light emitted from the pixel (311). For example, the opaque member (430) may partially overlap the pixel (321) among the pixel (311) and the pixel (321). For example, the opaque member (430) may be placed above or over a portion of the PDL (441) that defines the pixel (321) and the subpixels within the pixel (321) (e.g., subpixel (421) and subpixel (422)), and may not be placed above another portion of the PDL (441) that defines the pixel (311) and the subpixels within the pixel (311) (e.g., subpixel (411) and subpixel (412)). For example, the opaque member (430) may include an opening (431) (or a first light-transmitting portion (431) (or a first light-transmitting region (431)) placed over the pixel (311) and openings (432) (or second light-transmitting portions (432)) (or second light-transmitting regions (432)) placed over the pixel (321). The opening (431) may be aligned with the pixel (311). The opening (431) may overlap with subpixels within the pixel (311). The opening (431) may enclose the subpixels within the pixel (311) when the display panel (160) is viewed from above. The subpixels within the pixel (311) may be located within the opening (431) when the display panel (160) is viewed from above. The openings (432) are 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.

[0064] 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 subpixels (e.g., subpixel (421) and subpixel (422)) within the pixel (321) may be positioned respectively below the openings (432) (or the second light-transmitting portion (432)). The subpixels within the pixel (311) may be described as first subpixels positioned below one light-transmitting portion (e.g., first light-transmitting portion (431)) within another layer (402), and the subpixels within the pixel (321) may be described as second subpixels positioned respectively below other light-transmitting portions (e.g., second light-transmitting portions (432)) within another layer (402) that are smaller than the light-transmitting portion (e.g., first light-transmitting portion (431)) within the other layer (402).

[0065] As a non-limiting example, the width (w3) of one of the openings (432) may be equal to the width (w2) of the subpixel (421). As a non-limiting example, the width (w3) of one of the openings (432) may be wider than the width (w2) of the subpixel (421). As a non-limiting example, the width (w3) of one of the openings (432) may be narrower than the width (w2) of the subpixel (421).

[0066] As a non-limiting example, the display panel (160) may further include at least one layer disposed between layer (401) and another layer (402).

[0067] For example, the at least one layer may include a color filter layer (not shown). The color filter layer may include an opaque member (460) comprising opaque portions located between the PDL (441) and the opaque member (430). For example, the opaque member (460) included within the color filter layer of the display panel (160) may include (or define) an opening (461) (or 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 within the display panel (160) to guide light emitted (or transmitted) toward each of the openings (432). For example, light from a subpixel (421) may be emitted (or transmitted) to an opening (432) aligned with the subpixel (421) by means of an opaque member (460). For example, light from a subpixel (422) may be emitted (or transmitted) to an opening (432) aligned with the subpixel (422) by means of an opaque member (460). The color filter layer may be placed over, on, or above a touch layer between layer (401) and another layer (402). The touch layer may be used to identify touch inputs on the display panel (160).

[0068] 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).

[0069] The above-mentioned at least one layer may include an additional opaque member (460) in addition to the opaque member (430) of another layer (402). Accordingly, a double BM (black matrix) structure in which opaque members are formed in a plurality of layers may be formed. In the example of FIG. 4, the width (or diameter), size, and position (or arrangement) of the opaque member (430) and the opaque member (460) may be identical to each other. For example, each of the openings (461, 462) defined by the opaque member (460) may be substantially identical to each of the openings (431) and openings (432) of another layer (402). However, the present disclosure is not limited thereto. For example, each of the openings (461, 462) defined by the opaque member (460) may be different from the openings (431) and openings (432) corresponding to each opening. The width (or diameter), size, and center axis position (or alignment position) of the openings (431) and openings (432) of another layer (402), and the light-emitting part of the layer (401) (e.g., subpixel (411), subpixel (412), subpixel (421), subpixel (422)) may differ from the width (or diameter), size, and center axis position of the openings (461, 462) of the opaque member (460) included in the at least one layer.

[0070] The above at least one layer may include a color filter layer including an opaque member (460) and another layer including an opaque member (460). As a non-limiting example, the width (or diameter), size, and position (or placement) of the opaque member (460) of the color filter layer, the opaque member (460) of the other layer, and the opaque member (430) of the other layer (402) may be the same as each other. As a non-limiting example, the width (or diameter), size, and position (or placement) of the opaque members of two of the layers—the opaque member (460) of the color filter layer, the opaque member (460) of the other layer, and the opaque member (430) of the other layer (402)—may be the same as each other, and the width (or diameter), size, and position (or placement) of the opaque member of the remaining layer may be different from the width (or diameter), size, and position (or placement) of the opaque members of the two layers.

[0071] Figure 5 illustrates another example of the configuration of a display panel of an electronic device.

[0072] Referring to FIG. 5, the display panel (160) may include a plurality of pixels. For example, the display panel (160) may include first pixels (510) and second pixels (520). For example, the first pixels (510) may include pixels (511) and pixels (512). For example, the second pixels (520) may include pixels (521) and pixels (522). As an example without limitation, the first pixels (510) and the second pixels (520) may alternate with each other. As an example without limitation, the first pixels (510) and the second pixels (520) may be arranged in an interleaved arrangement.

[0073] The first pixels (510) may include subpixels. The subpixels may include a first subpixel (550-1) configured to emit light in a first color (e.g., red), a second subpixel (550-2) configured to emit light in a second color (e.g., green), and a third subpixel (550-3) configured to emit light in a third color (e.g., blue). The subpixels may further include a fourth subpixel (not shown) configured to emit light in a fourth color (e.g., white).

[0074] The second pixels (520) may include subpixels. The subpixels may include a first subpixel (560-1) configured to emit light in a first color (e.g., red), a second subpixel (560-2) configured to emit light in a second color (e.g., green), and a third subpixel (560-3) configured to emit light in a third color (e.g., blue). The subpixels may further include a fourth subpixel (not shown) configured to emit light in a fourth color (e.g., white).

[0075] 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).

[0076] 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.

[0077] Fig. 6 is a cross-sectional view of a display panel according to an example configuration of Fig. 5.

[0078] 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)).

[0079] 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).

[0080] 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).

[0081] 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).

[0082] 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 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).

[0083] 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).

[0084] 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).

[0085] Referring back to FIG. 2, the electronic device (101) may provide a 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 privacy display mode may be described as a display mode for reducing the probability that information within a screen displayed on the display panel (160) will be visible to another user distinct from the user of the electronic device (101). For example, the privacy display mode may be described as a display mode for reducing the probability that information within a 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 privacy display mode may be described as a display mode for reducing visibility from the second space. As a non-limiting example, the privacy display mode may include the first privacy display mode providing a viewing angle (182) or the second privacy display mode providing a viewing angle (183).

[0086] For example, the display driving circuit (221) may receive an image from at least one processor (210). For example, the image may correspond to a screen (e.g., screen (110) of FIG. 1) displayed through the display panel (160). For example, the display driving circuit (221) may use the first sub-pixels and the second sub-pixels to display the screen corresponding to the image through the display panel (160) according to the normal display mode. For example, the screen may be displayed according to the normal display mode by using light emitted from the first sub-pixels and light emitted from the second sub-pixels. For example, the display driving circuit (221) may use the second sub-pixels among the first sub-pixels and the second sub-pixels to display the screen corresponding to the image through the display panel (160) according to the privacy display mode (or the first privacy display mode). Alternatively, for example, the display driving circuit (221) may use the first sub-pixels and the second sub-pixels of each of the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) of the display panel (160) to display the screen corresponding to the image through the display panel (160) according to the privacy display mode (or the second privacy display mode).

[0087] The electronic device (101) may perform color data adjustment to uniformly (or identically) adjust the colors between parts of an image displayed through pixels of the display panel (160). For example, at least one processor (210) may generate an image to be displayed. For example, at least one processor (210) may transmit (provide) the image to be displayed to the display driving circuit (221). For example, the display driving circuit (221) may display the image on the display area of ​​the display panel (160) by applying color data of the received image to each of the first pixels and each of the second pixels of the display panel (160).

[0088] The display driving circuit (221) may adjust the color data of the image received from at least one processor (210) to uniformly (or identically) adjust the colors between portions of the image displayed through the pixels of the display panel (160). As a non-limiting example, the display driving circuit (221) may perform the first adjustment using a first correction value (e.g., the first correction value (731) of FIG. 7B) for adjusting the color data of first portions corresponding to the first pixels among the image displayed through the pixels of the display panel (160). As a non-limiting example, the display driving circuit (221) may perform the second adjustment using a second correction value (e.g., the second correction value (732) of FIG. 7B) for adjusting the color data of second portions corresponding to the second pixels among the image displayed through the pixels of the display panel (160). For example, the first adjustment and the second adjustment may be performed independently. For specific details related to this, reference can be made to Figure 7b below.

[0089] Color data adjustment can be performed using an image processing circuit (e.g., an image processing module (1135) of FIG. 11) within the display driving circuit (221). The color data adjustment can be performed by further considering burn-in compensation of pixels. For example, a circuit (or module) for burn-in compensation can be included within the image processing circuit.

[0090] At least one processor (210) can identify each of the first correction value and the second correction value, and transmit the identified first correction value and the second correction value to the display driving circuit (221). For example, at least one processor (210) can obtain characteristic information defined with respect to the first pixels among the pixels of the display panel (160) and stored in the display driving circuit (221), and identify the first correction value using the obtained characteristic information. For example, the characteristic information can be stored in a memory area (e.g., a multi-time programmable (MTP)) within the display driving circuit (221). For example, at least one processor (210) can obtain other characteristic information defined with respect to the second pixels among the pixels of the display panel (160) and stored in the display driving circuit (221), and identify the second correction value using the obtained other characteristic information. For example, the above characteristic information may be stored in the memory area within the display driving circuit (221). For specific details related thereto, reference may be made to FIGS. 8A to 8C below.

[0091] For specific details on the operation of the display driving circuit (221) to receive an image from at least one processor (210) and control the display panel (160) to display it through each pixel of the display panel (160), reference may be made to FIG. 7A below.

[0092] Figure 7a illustrates an example of a method for performing adjustment of color data of an image using the same correction value in the first pixel and the second pixel.

[0093] FIG. 7A illustrates an example of a method for performing adjustment of color data of an image (700) using the same correction value (730) in a first pixel (e.g., pixel (311) among the first pixels (310) of FIG. 3 or pixel (511) among the first pixels (510) of FIG. 5) and a second pixel (e.g., pixel (321) among the second pixels (320) of FIG. 3 or pixel (521) among the second pixels (520) of FIG. 5). The method of FIG. 7A may be performed by the electronic device (101) of FIG. 2.

[0094] Referring to FIG. 7A, at least one processor (210) of the electronic device (101) may transmit an image (700) to the display driving circuit (221). For example, the image (700) may include color data. For example, the image (700) may include data (hereinafter, referred to as R data) (e.g., 255) representing a first color (e.g., red color (R)) for representing a reference color (e.g., white), data (hereinafter, referred to as G data) (e.g., 255) representing a second color (e.g., green color (Green, G)), and data (hereinafter, referred to as B data) (e.g., 255) representing a third color (e.g., blue color (Blue, B)). In the above example, the color data may include R data, G data, and B data. However, the present disclosure is not limited thereto. Depending on the pentile structure of the display panel (160), the color data may further include data representing a fourth color (e.g., white). The color data may be referred to as grayscale data or grayscale levels. For example, the color data of the image (700) may be defined for each pixel of the display panel (160).

[0095] In the example of FIG. 7A, the screen (705) represents an example of a visual representation of the image (700) (or the color data of the image (700)). In other words, at least one processor (210) may generate the image (700) to display the screen (705). The screen (705) is not actually displayed on the display area of ​​the display panel (160), but may represent a screen that is expected to be displayed. In the example of FIG. 7A, the image (700) is illustrated when the reference color is white, but the present disclosure is not limited thereto. For example, the reference color may be another color (e.g., R, G, B).

[0096] In the example of FIG. 7A, the screen (711) represents an example of a visual representation for a case where an image (700) is displayed using a first pixel (710). The screen (711) is not actually displayed on the display area of ​​the display panel (160), but may represent a first portion of the image (700) corresponding to the first pixel (710) of the display panel (160) that is expected to be displayed. For example, the first portion of the image (700) may represent a portion of the image (700) to be displayed on the first pixel (710) (or, first sub-pixels of the first pixel (710) (e.g., sub-pixels (350-1, 350-2, 350-3) of the pixel (311) of FIG. 3 or sub-pixels (550-1, 550-2, 550-3) of the pixel (511) of FIG. 5).

[0097] In the above example, one first pixel (710) is described, but the present disclosure is not limited thereto. In the present disclosure, the description of the first pixel (710) can be substantially equally applied to the first pixels of the display panel (160) (e.g., the first pixels (310) of FIG. 3 and the first pixels (510) of FIG. 5).

[0098] Even if the display driving circuit (221) controls the display panel (160) to display color data (e.g., 255, 255, 255) of the image (700) through the first pixel (710), a screen (711) having a different color from the screen (705) may be displayed on the display area (or the first pixel (710)) of the display panel (160). As a non-limiting example, the screen (711) may be a greenish screen.

[0099] In the example of FIG. 7A, the screen (721) represents an example of a visual representation for a case where the image (700) is displayed using the second pixel (720). The screen (721) is not actually displayed on the display area of ​​the display panel (160), but may represent a second portion of the image (700) corresponding to the second pixel (720) of the display panel (160) that is expected to be displayed. For example, the second portion of the image (700) may represent a portion of the image (700) to be displayed in the second pixel (720) (or second sub-pixels of the second pixel (720) (e.g., sub-pixels (350-1, 350-2, 350-3) of the pixel (321) of FIG. 3 or sub-pixels (560-1, 560-2, 560-3) of the pixel (522) of FIG. 5).

[0100] In the above example, one second pixel (720) is described, but the present disclosure is not limited thereto. In the present disclosure, the description of the second pixel (720) can be substantially equally applied to the second pixels of the display panel (160) (e.g., the second pixels (320) of FIG. 3 and the second pixels (520) of FIG. 5).

[0101] Even if the display driving circuit (221) controls the display panel (160) to display color data (e.g., 255, 255, 255) of the image (700) through the second pixel (720), a screen (721) having a different color from the screen (705) may be displayed on the display area of ​​the display panel (160) (or the second pixel (720)). As a non-limiting example, the screen (721) may be a reddish screen.

[0102] Referring to the above, an image (700) received from at least one processor (210) is generated to display a screen (705), but when displayed on the first pixel (710) or the second pixel (720), screens (711, 721) having unintended colors may be displayed.

[0103] Screens (711, 721) having unintended colors may be caused based on differences in properties between pixels of the display panel (160). For example, components within a first pixel (710) (or first sub-pixels of the first pixel (710)) and components within a second pixel (720) (or second sub-pixels of the second pixel (720)) may be different from each other. As a non-limiting example, the components may include transistors or light-emitting elements within the pixels.

[0104] Alternatively, screens (711, 721) having unintended colors may be caused by coupling between the first pixel (710) and the second pixel (720). For example, the coupling may be caused by the effect of the voltage (and / or current) applied to the first pixel (710) on the second pixel (720) and the effect of the voltage (and / or current) applied to the second pixel (720) on the first pixel (710) when the line on which the first pixels including the first pixel (710) are arranged and the line on which the second pixels including the second pixel (720) are arranged are arranged to intersect each other. As a non-limiting example, one line may be connected to some of the first sub-pixels of the first pixel (710) and some of the second sub-pixels of the second pixel (720), and another line intersecting the line may be connected to the remaining sub-pixels of the first sub-pixels of the first pixel (710) and the remaining sub-pixels of the second sub-pixels of the second pixel (720). In the above example, it is assumed that the line is an odd line and the other line is an even line. For example, a signal (e.g., a gate signal, a gate voltage) applied to an odd line may also affect an even line depending on coupling. Accordingly, as the gate voltage of a transistor (or a driving transistor) of an even line increases, the current may decrease. In this case, the brightness of the pixels of the even line may decrease. The first pixel (710) and the second pixel (720) of the display panel (160) have different characteristics, and interference between the pixels may occur, resulting in screens (711, 721) having unintended colors (and / or brightness) being displayed.

[0105] In the example of FIG. 7a, it is assumed that the screen (711) is a green screen and the screen (721) is a red screen, but the present disclosure is not limited thereto.

[0106] The display driving circuit (221) can adjust the color data of the image (700) using the correction value (730) to prevent screens (711, 721) with unintended colors from being displayed. For example, the correction value (730) can be transmitted (or provided) to the display driving circuit (221) from at least one processor (210). In FIG. 7A, the correction value (730) is assumed to be a value for adjusting the color data of the image (700) to be displayed in the second pixel (720) (or the color data of the second part of the image (700). However, the present disclosure is not limited thereto. For example, the correction value (730) may also be a value for adjusting the color data of the image (700) to be displayed in the first pixel (710) (or the color data of the first part of the image (700). For example, the display driving circuit (221) can adjust the color data (e.g., 255, 255, 255) of the image (700) to color data (e.g., 240, 255, 240) using the correction value (730). When the screen is displayed through each of the first pixel (710) and the second pixel (720) using the adjusted color data (e.g., 240, 255, 240), it can be expected that the screens (712, 722) will be displayed.

[0107] In the example of FIG. 7A, the screen (712) represents an example of a visual representation for a case where adjusted color data (e.g., 240, 255, 240) of the image (700) is displayed using the first pixel (710). The screen (712) is not actually displayed on the display area of ​​the display panel (160), but may represent the first portion of the image (700) corresponding to the first pixel (710) of the display panel (160) that is expected to be displayed. Even if the display driving circuit (221) controls the display panel (160) to display the adjusted color data (e.g., 240, 255, 240) of the image (700) through the first pixel (710), the screen (712) having a different color from the screen (705) may be displayed on the display area (or the first pixel (710)) of the display panel (160). As a non-limiting example, screen (712) may be a more greenish screen than screen (711).

[0108] In the example of FIG. 7A, the screen (722) represents an example of a visual representation for a case where the image (700) is displayed using the second pixel (720). The screen (722) is not actually displayed on the display area of ​​the display panel (160), but may represent the second portion of the image (700) corresponding to the second pixel (720) of the display panel (160) that is expected to be displayed. As the display driving circuit (221) controls the display panel (160) to display the adjusted color data (e.g., 240, 255, 240) of the image (700) through the second pixel (720), the screen (722) having the same (or substantially the same, corresponding, uniformity) color as the screen (705) can be displayed on the display area of ​​the display panel (160) (or the second pixel (720)).

[0109] In the example of FIG. 7A, the display driver circuit (221) can perform the same adjustment (adjustment for color uniformity, color correction) on the color data (e.g., 255, 255, 255) of the image (700) for each of the first pixel (710) and the second pixel (720) using the correction value (730). For example, the adjustment for color uniformity may refer to adjusting the color data so that the color displayed at the first pixel (710) and the color displayed on the display panel (160) through the second pixel (720) appear substantially the same. By using the correction value (730), the color adjustment for the second portion of the image (700) displayed at the second pixel (720) can be performed so that an intended color (e.g., white) is displayed. However, since one correction value (730) is used equally for the first pixel (710), color adjustment of the first portion of the image (700) displayed at the first pixel (710) may be performed so that an unintended color (e.g., green) is displayed.

[0110] Accordingly, when the display driving circuit (221) controls the display to display the corrected image (740) (or the color data (e.g., 240, 255, 240) of the corrected image (740)) on the display panel (160), a screen (745) may be displayed. The screen (745) may represent a screen in which the corrected image (740) including the first portion and the second portion corresponding to the first pixel (710) and the second pixel (720) are displayed on the display area of ​​the display panel (160). For example, the screen (745) may be generated by synthesizing the screen (722) and the screen (712). Referring to the example of FIG. 7A, the screen (745) may be a screen that is less greenish than the screen (712) and has a color similar to the screen (711).

[0111] In the example of FIG. 7A, the screen (745) assumes the case of the normal display mode in which the corrected image (740) is displayed through both the first pixel (710) and the second pixel (720), but the present disclosure is not limited thereto. For example, the display driving circuit (221) may display the corrected image (740) through the second pixel (720) among the first pixel (710) and the second pixel (720) in the privacy display mode (or the first privacy display mode). In this case, an example of the screen displayed on the display area of ​​the display panel (160) may be the screen (722). In addition, the display driving circuit (221) may display the corrected image (740) through the first pixel (710) and the second pixel (720) among some of the first pixels of the display panel (160) in the privacy display mode (or the second privacy display mode). In this case, an example of a screen displayed on the display area of ​​the display panel (160) may be a screen having a color between the screen (722) and the screen (745) (or a greenish screen).

[0112] As described above, when the electronic device (101) displays a screen using an image (e.g., an image (700) or color data of the image (700)) depending on the display mode of the display (220), a difference in color between the screen according to the color data used when generating the image and the color on the screen actually displayed may occur. Accordingly, the picture quality of the display (220) may be lowered, and inconvenience may be caused to the user. Hereinafter, the present disclosure independently performs adjustment (or adjustment for color uniformity, color correction) on each of the first pixel (710) and the second pixel (720) of the display panel (160), thereby reducing (or eliminating) the difference in color on the screen actually displayed even when the display mode is changed. For example, the adjustment performed on the first pixel (710) may use a first correction value, and the adjustment performed on the second pixel (720) may use a second correction value different from the first correction value. Accordingly, the present disclosure can improve a user's viewing experience by providing uniform picture quality on the display (220).

[0113] For specific details on the case where adjustments are independently performed for each of the first pixel (710) and the second pixel (720) of the display panel (160), reference may be made to FIG. 7b.

[0114] FIG. 7b illustrates an example of a method for independently performing adjustment of color data of an image using a first correction value at a first pixel and a second correction value at a second pixel.

[0115] FIG. 7B illustrates an example of a method for independently performing adjustment of color data of an image (700) on a pixel-by-pixel basis by using a first correction value (731) in a first pixel (e.g., pixel (311) among the first pixels (310) of FIG. 3 or pixel (511) among the first pixels (510) of FIG. 5) and a second correction value (732) in a second pixel (e.g., pixel (321) among the second pixels (320) of FIG. 3 or pixel (521) among the second pixels (520) of FIG. 5). The method of FIG. 7B may be performed by the electronic device (101) of FIG. 2. At least a part of the method of FIG. 7B may be substantially identically referenced to the example of FIG. 7A. The same reference numerals may be used for the same description.

[0116] Referring to FIG. 7B, at least one processor (210) of the electronic device (101) may transmit an image (700) to the display driving circuit (221). For example, the image (700) may include color data. For example, the image (700) may include data (hereinafter, referred to as R data) (e.g., 255) representing a first color (e.g., red color (R)) for representing a reference color (e.g., white), data (hereinafter, referred to as G data) (e.g., 255) representing a second color (e.g., green color (G)), and data (hereinafter, referred to as B data) (e.g., 255) representing a third color (e.g., blue color (Blue, B)). In the example of FIG. 7B, the screen (705) represents an example of a visual representation of the image (700) (or the color data of the image (700)). In other words, at least one processor (210) may generate an image (700) to display a screen (705). The screen (705) may not actually be displayed on the display area of ​​the display panel (160), but may represent a screen that is expected to be displayed.

[0117] In the example of FIG. 7B, the screen (711) represents an example of a visual representation for a case where an image (700) is displayed using the first pixel (710). Even if the display driving circuit (221) controls the display panel (160) to display color data (e.g., 255, 255, 255) of the image (700) through the first pixel (710), a screen (711) having a different color from the screen (705) may be displayed on the display area of ​​the display panel (160) (or the first pixel (710)). As a non-limiting example, the screen (711) may be a greenish screen.

[0118] In the example of FIG. 7B, the screen (721) represents an example of a visual representation for a case where the image (700) is displayed using the second pixel (720). Even if the display driving circuit (221) controls the display panel (160) to display the color data (e.g., 255, 255, 255) of the image (700) through the second pixel (720), a screen (721) having a different color from the screen (705) may be displayed on the display area of ​​the display panel (160) (or the second pixel (720)). As a non-limiting example, the screen (721) may be a reddish screen.

[0119] Referring to the above, an image (700) received from at least one processor (210) is generated to display a screen (705), but when displayed on the first pixel (710) or the second pixel (720), screens (711, 721) having unintended colors may be displayed.

[0120] The display driving circuit (221) can adjust the color data of the image (700) using correction values ​​(731, 732) to prevent screens (711, 721) with unintended colors from being displayed. For example, the correction values ​​(731, 732) can be transmitted (or provided) to the display driving circuit (221) from at least one processor (210).

[0121] As a non-limiting example, at least one processor (210) may identify a first correction value (731) for a first pixel (710) and a second correction value (732) for a second pixel (720), respectively. For example, at least one processor (210) may acquire (or receive, read) characteristic information of a display panel (160) stored within a display driving circuit (221). For example, the characteristic information may be stored within an MTP (multi-time programmable) (or MTP area, MTP storage space) of the display driving circuit (221).

[0122] For example, the characteristic information may include information about a color shown through the first pixels of the display panel (160) (or display (220)) when the display panel (160) (or display (220)) is produced, when an image representing a reference color (e.g., white) is displayed through the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) among the pixels of the display panel (160). For example, the characteristic information may include color coordinates for the shown color. As a non-limiting example, the color coordinates may represent coordinates within a CIE color space (or a CIE 1931 color space). As a non-limiting example, the characteristic information may include color temperature and chrominance information for the shown color. As a non-limiting example, the characteristic information may include information about a color shown through the first pixels of the display panel (160), as the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) among the pixels of the display panel (160) display an image that represents a color (e.g., R, G, B) different from a reference color (e.g., white) through the reference color.

[0123] In the above example, the characteristic information is exemplified when an image representing a reference color (e.g., white) is displayed through first pixels (e.g., first pixels (310) of FIG. 3 or first pixels (510) of FIG. 5) among the pixels of the display panel (160), but the present disclosure is not limited thereto. For example, other characteristic information may be considered when an image representing a reference color (e.g., white) is displayed through second pixels (e.g., second pixels (320) of FIG. 3 or second pixels (520) of FIG. 5) among the pixels of the display panel (160). For example, at least one processor (210) may acquire (or receive) the other characteristic information stored in the display driving circuit (221) (or, MTP). Alternatively, for example, when displaying an image representing a reference color (e.g., white) through at least some of the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) among the pixels of the display panel (160) and the second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) among the pixels of the display panel (160), further characteristic information may be acquired (or received). For example, at least one processor (210) may acquire (or receive) the further characteristic information stored in the display driving circuit (221) (or the MTP).

[0124] In the above example, the use of characteristic information stored within the display driving circuit (221) is described, but the present disclosure is not limited thereto. For example, at least one processor (210) may also use information measured using a measuring instrument for measuring characteristics of the display panel (160) (or display (220)).

[0125] At least one processor (210) can identify a first correction value (731) using the above characteristic information, and can identify a second correction value (732) using the other characteristic information. For specific details related thereto, reference may be made to FIGS. 8A to 8C below.

[0126] For example, the display driving circuit (221) can adjust the color data (e.g., 255, 255, 255) of the image (700) to color data (e.g., 255, 240, 255) using the first correction value (731). When the screen is displayed through the first pixel (710) using the adjusted color data (e.g., 255, 240, 255), the screen (713) can be expected to be displayed. In the example of FIG. 7B, the screen (713) represents an example of a visual representation for the case where the adjusted color data (e.g., 255, 240, 255) of the image (700) is displayed using the first pixel (710).

[0127] For example, the display driving circuit (221) can adjust the color data (e.g., 255, 255, 255) of the image (700) to color data (e.g., 240, 255, 240) using the second correction value (732). When the screen is displayed through the second pixel (720) using the adjusted color data (e.g., 240, 255, 240), the screen (723) can be expected to be displayed. In the example of FIG. 7B, the screen (723) represents an example of a visual representation for the case where the adjusted color data (e.g., 240, 255, 240) of the image (700) is displayed using the second pixel (720).

[0128] In the example of FIG. 7B, the screen (713) is not actually displayed on the display area of ​​the display panel (160), but may represent the first part of the image (700) corresponding to the first pixel (710) of the display panel (160) that is expected to be displayed. As the display driving circuit (221) controls the display panel (160) to display the adjusted color data (e.g., 255, 240, 255) of the image (700) through the first pixel (710), the screen (713) having the same (or substantially the same, corresponding, uniformity) color as the screen (705) may be displayed on the display area (or the first pixel (710)) of the display panel (160).

[0129] In the example of FIG. 7B, the screen (723) is not actually displayed on the display area of ​​the display panel (160), but may represent the second part of the image (700) corresponding to the second pixel (720) of the display panel (160) that is expected to be displayed. As the display driving circuit (221) controls the display panel (160) to display the adjusted color data (e.g., 240, 255, 240) of the image (700) through the second pixel (720), the screen (723) having the same (or substantially the same, corresponding, uniformity) color as the screen (705) may be displayed on the display area of ​​the display panel (160) (or the second pixel (720)).

[0130] In the example of FIG. 7b, the display driving circuit (221) can independently perform adjustment (adjustment for color uniformity, color correction) on the color data (e.g., 255, 255, 255) of the image (700) for the first pixel (710) using the first correction value (731) and adjustment on the color data (e.g., 255, 255, 255) of the image (700) for the second pixel (720) using the second correction value (732).

[0131] By using the correction values ​​(731, 732), a first adjustment to the first portion of the image (700) displayed at the first pixel (710) and a second adjustment to the second portion of the image (700) displayed at the second pixel (720) can be performed so that an intended color (e.g., white) is displayed.

[0132] When the display driving circuit (221) controls the display to display the corrected image (750) (or the color data of the first part of the corrected image (750) (e.g., 255, 240, 255) and the color data of the second part of the corrected image (750) (e.g., 240, 255, 240)) on the display panel (160), a screen (755) may be displayed. The screen (755) may represent a screen in which the corrected image (750) including the first part and the second part corresponding to the first pixel (710) and the second pixel (720) are displayed on the display area of ​​the display panel (160). Unlike the example of FIG. 7A, referring to the example of FIG. 7B, the screen (755) may be a screen having a reference color (e.g., white) like the screen (705).

[0133] As a non-limiting example, each of the first correction value (731) and the second correction value (732) may be determined based on control (or wide pixel control) for the first pixels of the display panel (160) (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5). For example, each of the first correction value (731) and the second correction value (732) may be adjusted based on the ratio of the first pixels used for light emission (or turned on) among all the first pixels included in the display panel (160), or the number of the total first pixels. For example, the ratio may be referred to as the intensity of the privacy display mode (e.g., the first level (or high), the second level (or middle), the third level (or low)). As the ratio of the first pixels used for light emission among the entire first pixels of the display panel (160) changes, the current flowing to the second pixels (or the sub-pixels of the second pixels, the transistors of each of the sub-pixels of the second pixels) electrically connected to the first pixels used for light emission (or connected to the line to which the first pixels used for light emission are connected) may change. In order to adjust the change in the current, each of the first correction value (731) and the second correction value (732) may be adjusted based on the ratio of the first pixels used for light emission (or turned on) among the entire first pixels included in the display panel (160), or the number of the entire first pixels.

[0134] As a non-limiting example, each of the first correction value (731) and the second correction value (732) may be determined based on the usage time of the display panel (160) (or the usage time of the electronic device (101)) for burn-in compensation. For example, the usage time of the display panel (160) may be referenced as the emission time of the pixels of the display panel (160). For example, each of the first correction value (731) and the second correction value (732) may be adjusted for burn-in compensation based on the usage time of the display panel (160).

[0135] Referring to FIGS. 7A and 7B , the display driving circuit (221) may adjust the color data of an image using different correction values ​​(e.g., the first correction value (731) and the second correction value (732)) instead of using the same correction value (e.g., the correction value (730)) for pixels having different FOIs (e.g., the first pixel (710) and the second pixel (720)). Accordingly, the present disclosure may reduce the color difference between the pixels of the display panel (160). Reducing the color difference may be referred to as adjusting color data, color adjustment, color uniformity, and color correction. For specific details on at least one processor (210) identifying a correction value for each pixel, reference may be made to FIGS. 8A to 8C below.

[0136] FIGS. 8A to 8C illustrate examples of a method for identifying a correction value using color coordinates for a reference color of a display panel and reference color coordinates for the reference color.

[0137] FIGS. 8A to 8C illustrate examples (801, 802, 803) of a method for identifying a correction value by using color coordinates (809) and reference color coordinates (810, 820) included in the characteristic information of the display panel (160). For example, the color coordinates (809) may be included in the characteristic information when an image representing a reference color (e.g., white) is displayed. For example, the reference color coordinates (810, 820) may be coordinates within a color space representing the reference color (e.g., white) defined for the first pixel (710) (or first sub-pixels of the first pixel (710)) of FIGS. 7A and 7B. For example, the reference color coordinates (810, 820) may be stored in advance within the electronic device (101) (or within the memory (230)) for the first pixel (710).

[0138] FIGS. 8A to 8C illustrate a case in which a correction value (e.g., a first correction value (731) of FIG. 7B) to be applied to a first pixel (710) is identified using the color coordinates (809) included in the characteristic information of the first pixel (710) (or, first sub-pixels of the first pixel (710)) of FIGS. 7A and 7B, but the present disclosure is not limited thereto. For example, even in a case in which a correction value (e.g., a second correction value (732) of FIG. 7B) to be applied to a second pixel (720) is identified using the color coordinates included in the characteristic information of the second pixel (720) (or, second sub-pixels of the second pixel (720)) of FIGS. 7A and 7B, examples (801, 802, 803) of FIGS. 8A to 8C can be substantially equally applied. In addition, examples (801, 802, 803) of FIGS. 8A to 8C can be substantially equally applied in cases where the correction values ​​of each of the first pixel (710) and the second pixel (720) are identified by using color coordinates included in characteristic information indicating when some of the first pixels and the second pixels of the first pixels of the display panel (160) are displayed.

[0139] Referring to example (801) of FIG. 8A, at least one processor (210) can identify color coordinates (809) by acquiring (or, by receiving, by reading) characteristic information stored in the display driving circuit (221). For example, the color coordinates (809) may be (a, b). For example, the color coordinates (809) may be included in a color space. In FIGS. 8A to 8C, for convenience of explanation, the color space may be defined by (x, y), excluding a coordinate representing brightness (e.g., Y) among the coordinates (e.g., x, y, Y).

[0140] At least one processor (210) can identify reference color coordinates (810, 820) stored in the electronic device (101). For example, the reference color coordinates (810, 820) can be defined by a color region (830) (or range) representing the reference color within the color space. For example, the color region (830) can be referred to as a color scatter representing the reference color. In other words, the color region (830) can represent a portion within the color space that can be recognized (visible) as the reference color. In the example (801) of FIG. 8A, for convenience of explanation, the color region (830) is illustrated as being formed as a square, but the present disclosure is not limited thereto. For example, the color region (830) can also be formed as a circle, a rhombus, or a parallelogram.

[0141] The reference color coordinates (810, 820) may include a first reference color coordinate (810) and second reference color coordinates (820). For example, the first reference color coordinate (810) may be a reference coordinate (or representative coordinate) representing the reference color. For example, the first reference color coordinate (810) may be located at the center of the color area (830). As a non-limiting example, color data corresponding to the first reference color coordinate (810) may be (255, 255, 255). For example, the second reference color coordinates (820) may be coordinates located at the edge of the color area (830) representing the reference color. In the example (801), the second reference color coordinates (820) may include eight coordinates. As a non-limiting example, color data corresponding to the second reference color coordinates (820) may be (249, 247, 255), (249, 251, 255), (249, 255, 255), (251, 255, 251), (251, 255, 248), (255, 253, 250), (255, 249, 249), and (255, 250, 254). In the present disclosure, a case where each color data is 8-bit data is exemplified, but the present disclosure is not limited thereto.

[0142] At least one processor (210) may divide the color gamut (830) into a plurality of color gamut parts to identify color data corresponding to color coordinates (809). For specific details related thereto, reference may be made to FIG. 8B.

[0143] Referring to example (802) of FIG. 8B, the color gamut (830) of example (801) of FIG. 8A is illustrated as four color gamut portions (831, 832, 833, 834) distinguished by two virtual lines (841, 842). In example (802) of FIG. 8B, the color gamut (830) is illustrated as being distinguished into four color gamut portions (831, 832, 833, 834) by two lines (841, 842), but the present disclosure is not limited thereto. For example, the number of lines may be defined differently from example (802).

[0144] At least one processor (210) can identify an equation (or an equation of a straight line) defining each of lines (841) and lines (842). For example, line (841) can be defined based on second reference color coordinates representing color data (e.g., 255, 250, 254) and second reference color coordinates representing color data (e.g., 251, 255, 251). For example, line (842) can be defined based on second reference color coordinates representing color data (e.g., 249, 251, 255) and second reference color coordinates representing color data (e.g., 255, 253, 250). At least one processor (210) can identify a color gamut portion (832) in which the color coordinate (809) is located among the color gamut portions (831, 832, 833, 834) by comparing the color coordinate (809) with equations of lines (841) and (842), respectively. As a non-limiting example, the at least one processor (210) can identify that the color coordinate (809) is located within the color gamut portion (832) or the color gamut portion (834) by comparing the color coordinate (809) with equations of lines (841), and then can identify that the color coordinate (809) is located within the color gamut portion (832) among the color gamut portions (832) and (834) by comparing the color coordinate (809) with equations of lines (842).

[0145] At least one processor (210) can identify color data corresponding to the color coordinates (809) by using reference color coordinates defined for the color gamut portion (832) after identifying the color gamut portion (832) where the color coordinates (809) are located. For specific details related thereto, reference may be made to FIG. 8C.

[0146] Referring to example (803) of FIG. 8c, a color gamut portion (832) in which a color coordinate (809) is located is illustrated among four color gamut portions (831, 832, 833, 834) included in the color gamut (830) of example (802) of FIG. 8b. For example, the color gamut portion (832) may be defined by a first reference color coordinate (810), a second reference color coordinate (821), a second reference color coordinate (822), and a second reference color coordinate (823). Color data corresponding to the first reference color coordinate (810) may be (255, 255, 255). Color data corresponding to the second reference color coordinate (821) may be (255, 250, 254). The color data corresponding to the second reference color coordinate (822) may be (249, 247, 255). The color data corresponding to the second reference color coordinate (823) may be (249, 251, 255).

[0147] At least one processor (210) can identify color data corresponding to the color coordinates (809) by performing interpolation based on the first reference color coordinates (810), the second reference color coordinates (821), the second reference color coordinates (822), and the second reference color coordinates (823) of the color gamut portion (832) where the color coordinates (809) are located. In performing the interpolation, the at least one processor (210) can normalize the color gamut portion (832). The first reference color coordinates (810) can be normalized to (0, 0), the second reference color coordinates (821) to (0, 1), the second reference color coordinates (822) to (1, 1), and the second reference color coordinates (823) to (1, 0). In example (803), within the normalized color gamut (832), the normalized color coordinates (809) (e.g., (a, b)) may be (0.6, 0,9). At least one processor (210) may identify color data corresponding to the color coordinates (809) using the following mathematical equation.

[0148]

[0149] The above A may be color data (e.g., 255, 255, 255) of the first reference color coordinate (810), the above B may be color data (e.g., 249, 251, 255) of the second reference color coordinate (823), the above C may be color data (e.g., 255, 250, 254) of the second reference color coordinate (821), the above D may be color data (e.g., 249, 247, 255) of the second reference color coordinate (822), the above a may be an x-coordinate (e.g., 0.6) of the normalized color coordinate (809), and the above b may be a y-coordinate (e.g., 0.9) of the normalized color coordinate (809).

[0150] In example (803), at least one processor (210) can identify color data (e.g., 251, 249, 255) corresponding to color coordinates (809) using the mathematical formula described above. For example, the color data (e.g., 251, 249, 255) corresponding to color coordinates (809) can be identified as a correction value (e.g., first correction value (731)) for the first pixel (710) of the display panel (160).

[0151] At least one processor (210) can identify color data (e.g., 251, 249, 255) corresponding to color coordinates (809) defined with respect to the first pixel (710) as a correction value. For example, when color data (e.g., 251, 249, 255) corresponding to color coordinates (809) of the display panel (160) is displayed through a display area (or, the first pixel (710)) of the display panel (160), a color shown in a portion of the image corresponding to the display area can be defined as color data (e.g., 255, 255, 255) corresponding to the first reference color coordinates (810). In other words, in order for the color data (e.g., 255, 255, 255) corresponding to the first reference color coordinates (810) to be actually displayed through the first pixel (710), the color data applied (or provided) through the first pixel (710) may be color data corresponding to the color coordinates (809). Accordingly, at least one processor (210) may identify the color data (e.g., 251, 249, 255) corresponding to the color coordinates (809) defined with respect to the first pixel (710) as a correction value.

[0152] Figure 9 shows examples of reference color coordinates for a reference color.

[0153] FIG. 9 illustrates examples (901, 902, 903) of reference color coordinates for generating a compensation value using color coordinates included in characteristic information for a display panel (160) (or display (200)). For example, the reference color coordinates may include reference color coordinates for a reference color (e.g., white). For example, the reference color coordinates may be stored in the electronic device (101) (or memory (230)).

[0154] Example (901) illustrates reference color coordinates (810, 820) that define a color area representing the reference color when an image representing the reference color is displayed through the first pixels among the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) and the second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) of the display panel (160). For example, the reference color coordinates (810, 820) may include the first reference color coordinates (810) and the second reference color coordinates (820). The first reference color coordinates (810) and the second reference color coordinates (820) may be examples of the first reference color coordinates (810) and the second reference color coordinates (820) of FIGS. 8A to 8C.

[0155] Example (902) illustrates reference color coordinates (810, 920) defining a color gamut representing the reference color when an image representing the reference color is displayed through the second pixels among the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) and the second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) of the display panel (160). As a non-limiting example, the color gamut representing the reference color of example (902) may be different from the color gamut representing the reference color of example (901) and the color gamut representing the reference color of example (903). For example, the reference color coordinates (810, 920) may include first reference color coordinates (810) and third reference color coordinates (920). The first reference color coordinates (810) of example (902) may be the same as the first reference color coordinates (810) of example (901) and the first reference color coordinates (810) of example (903). The third reference color coordinates (920) of example (902) may be different from the second reference color coordinates (920) of example (901) and the fourth reference color coordinates (930) of example (903).

[0156] Example (903) illustrates reference color coordinates (810, 930) defining a color area representing the reference color when an image representing the reference color is displayed through some of the first pixels and the second pixels among the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) and the second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) of the display panel (160). As a non-limiting example, the color area representing the reference color of example (903) may be different from the color area representing the reference color of example (901) and the color area representing the reference color of example (902). For example, the reference color coordinates (810, 930) may include the first reference color coordinate (810) and the fourth reference color coordinates (930). The first reference color coordinates (810) of example (903) may be the same as the first reference color coordinates (810) of example (901) and the first reference color coordinates (810) of example (902). The fourth reference color coordinates (930) of example (903) may be different from the second reference color coordinates (820) of example (901) and the third reference color coordinates (920) of example (902).

[0157] Referring to example (903), when an image representing the reference color is displayed through some of the first pixels and the second pixels among the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) and the second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) of the display panel (160), the reference color coordinates defining the color area representing the reference color may include a plurality of sets. As a non-limiting example, when the number of the some of the first pixels is a first number, the reference color coordinates defining the color area representing the reference color may be the reference color coordinates (810, 930) of the first set among the plurality of sets. As a non-limiting example, if the number of the first pixels of the above part is a second number that is greater than the first number, the reference color coordinates defining the color area representing the reference color may be reference color coordinates of a second set among the plurality of sets.

[0158] At least one processor (210) can identify a first correction value for adjusting color data of a portion of an image to be displayed through each of first pixels among pixels of the display panel (160) and a second correction value for adjusting color data of a portion of an image to be displayed through each of second pixels among pixels of the display panel (160) by using reference color coordinates for the reference color.

[0159] The operations described above can be performed by the electronic device (1001) in FIG. 10.

[0160] FIG. 10 is a block diagram of an electronic device within a network environment according to various embodiments.

[0161] Referring to FIG. 10, in a network environment (1000), an electronic device (1001) may communicate with an electronic device (1002) via a first network (1098) (e.g., a short-range wireless communication network), or may communicate with at least one of an electronic device (1004) or a server (1008) via a second network (1099) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1001) may communicate with the electronic device (1004) via the server (1008). According to one embodiment, the electronic device (1001) may include a processor (1020), a memory (1030), an input module (1050), an audio output module (1055), a display module (1060), an audio module (1070), a sensor module (1076), an interface (1077), a connection terminal (1078), a haptic module (1079), a camera module (1080), a power management module (1088), a battery (1089), a communication module (1090), a subscriber identification module (1096), or an antenna module (1097). In some embodiments, the electronic device (1001) may omit at least one of these components (e.g., the connection terminal (1078)), or may have one or more other components added. In some embodiments, some of these components (e.g., sensor module (1076), camera module (1080), or antenna module (1097)) may be integrated into a single component (e.g., display module (1060)).

[0162] The processor (1020) may, for example, execute software (e.g., a program (1040)) to control at least one other component (e.g., a hardware or software component) of the electronic device (1001) connected to the processor (1020) and perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (1020) may store commands or data received from other components (e.g., a sensor module (1076) or a communication module (1090)) in the volatile memory (1032), process the commands or data stored in the volatile memory (1032), and store result data in the non-volatile memory (1034). According to one embodiment, the processor (1020) may include a main processor (1021) (e.g., a central processing unit or an application processor) or a secondary processor (1023) (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together with the main processor (1021). For example, when the electronic device (1001) includes the main processor (1021) and the secondary processor (1023), the secondary processor (1023) may be configured to use less power than the main processor (1021) or to be specialized for a given function. The secondary processor (1023) may be implemented separately from the main processor (1021) or as a part thereof.

[0163] The auxiliary processor (1023) may control at least a portion of functions or states associated with at least one component (e.g., the display module (1060), the sensor module (1076), or the communication module (1090)) of the electronic device (1001), for example, on behalf of the main processor (1021) while the main processor (1021) is in an inactive (e.g., sleep) state, or together with the main processor (1021) while the main processor (1021) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1023) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1080) or a communication module (1090)). In one embodiment, the auxiliary processor (1023) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (1001) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (1008)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above. In addition to, or alternatively to, a hardware structure, an artificial intelligence model may include a software structure.

[0164] The memory (1030) can store various data used by at least one component (e.g., the processor (1020) or the sensor module (1076)) of the electronic device (1001). The data can include, for example, software (e.g., the program (1040)) and input data or output data for commands related thereto. The memory (1030) can include volatile memory (1032) or non-volatile memory (1034).

[0165] The program (1040) may be stored as software in memory (1030) and may include, for example, an operating system (1042), middleware (1044), or an application (1046).

[0166] The input module (1050) can receive commands or data to be used in a component of the electronic device (1001) (e.g., a processor (1020)) from an external source (e.g., a user) of the electronic device (1001). The input module (1050) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g., a stylus pen).

[0167] The audio output module (1055) can output audio signals to the outside of the electronic device (1001). The audio output module (1055) can include, for example, a speaker or a receiver.

Among these communication modules, a corresponding communication module can communicate with an external electronic device (1004) via a first network (1098) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (1099) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (1092) can verify or authenticate the electronic device (1001) within a communication network such as the first network (1098) or the second network (1099) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (1096).

[0178] The wireless communication module (1092) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology).

[0183] FIG. 11 is a block diagram of a display module according to various embodiments.

[0184] Referring to FIG. 11, a display module (1060) may include a display panel (1110) and a display driver IC (DDI) (1130) for controlling the same. The DDI (1130) may include an interface module (1131), a memory (1133) (e.g., a buffer memory), an image processing module (1135), or a mapping module (1137). The DDI (1130) 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 (1001) through the interface module (1131). For example, according to one embodiment, image information may be received from a processor (1020) (e.g., a main processor (1021) (e.g., an application processor) or an auxiliary processor (1023) (e.g., a graphics processing unit) that operates independently of the function of the main processor (1021). The DDI (1130) may communicate with a touch circuit (1150) or a sensor module (1076) through the interface module (1131). In addition, the DDI (1130) may store at least a part of the received image information in the memory (1133), for example, in units of frames. The image processing module (1135) may, for example, perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least a part of the image data based at least on the characteristics of the image data or the characteristics of the display panel (1110). The mapping module (1137) may output a voltage value corresponding to the image data preprocessed or postprocessed through the image processing module (1135). Alternatively, a current value may be generated. In one embodiment, the generation of the voltage value or current value may be performed at least in part based on, for example, the properties of the pixels of the display panel (1110), such as the arrangement of the pixels (RGB stripe or pentile structure), or the size of each sub-pixel.At least some pixels of the display panel (1110) may be driven based at least in part on, for example, the voltage value or current value, so that visual information (e.g., text, an image, or an icon) corresponding to the image data may be displayed through the display panel (1110).

[0185] According to one embodiment, the display module (1060) may further include a touch circuit (1150). The touch circuit (1150) may include a touch sensor (1151) and a touch sensor IC (1153) for controlling the same. The touch sensor IC (1153) may control the touch sensor (1151) to detect, for example, a touch input or a hovering input for a specific location of the display panel (1110). For example, the touch sensor IC (1153) may detect a touch input or a 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 panel (1110). The touch sensor IC (1153) may provide information (e.g., location, area, pressure, or time) regarding the detected touch input or hovering input to the processor (1020). According to one embodiment, at least a portion of the touch circuit (1150) (e.g., touch sensor IC (1153)) may be included as part of the display driver IC (1130), or as part of the display panel (1110), or as part of another component (e.g., auxiliary processor (1023)) disposed external to the display module (1060).

[0186] According to one embodiment, the display module (1060) 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 (1076), 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 (1060) (e.g., the display panel (1110) or the DDI (1130)) or a part of the touch circuit (1150). For example, when the sensor module (1076) embedded in the display module (1060) 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 panel (1110). For another example, when the sensor module (1076) embedded in the display module (1060) includes a pressure sensor, the pressure sensor can obtain pressure information associated with a touch input through a part or the entire area of ​​the display panel (1110). According to one embodiment, the touch sensor (1151) or the sensor module (1076) can be placed between pixels of a pixel layer of the display panel (1110), or above or below the pixel layer.

[0187] Figure 12 illustrates an example of an exemplary rollable electronic device.

[0188] Referring to FIG. 12, the electronic device (101) may include a display (1230), a first housing (1210), and / or a second housing (1220). The electronic device (101) of FIG. 12 may represent an example of the electronic device (101) of FIG. 1 or the electronic device (101) of FIG. 2. For example, the display (1230) of FIG. 12 may include a display panel (160) of the electronic device (101).

[0189] For example, the first housing (1210) may be referred to as a first housing part. The second housing (1220) may be referred to as a second housing part. For example, the electronic device (101) may include a housing including the first housing part and the second housing part.

[0190] In one embodiment, the first housing (1210) can accommodate at least a portion of the second housing (1220). The first housing (1210) can enclose (or surround) at least a portion of the second housing (1220).

[0191] In one embodiment, the second housing (1220) may be movable relative to the first housing (1210). The second housing (1220) may be movable linearly relative to the first housing (1210). The second housing (1220) may be slidable relative to the first housing (1210). For example, the second housing (1220) may be movable relative to the first housing (1210) in a first direction (d1) and / or a second direction (d2) opposite to the first direction (d1). As the second housing (1220) moves in the first direction (d1), the second housing (1220) may slide outward from the first housing (1210). As the second housing (1220) moves in the second direction (d2), the second housing (1220) can slide into the inside of the first housing (1210). The movement of the second housing (1220) relative to the first housing (1210) can change the state of the electronic device (101). The state of the electronic device (101) can include a slide-in state and / or a slide-out state. Within the slide-in state of the electronic device (101), the second housing (1220) can move in the first direction (d1) among the first direction (d1) and the second direction (d2) relative to the first housing (1210). For example, within the slide-in state of the electronic device (101), the second housing (1220) can move only in the first direction (d1). Within the slide-out state of the electronic device (101), the second housing (1220) may be movable in a first direction (d1) and a second direction (d2) with respect to the first housing (1210), among the second directions (d2). For example, within the slide-out state of the electronic device (101), the second housing (1220) may be movable only in the second direction (d2).

[0192] According to one embodiment, the display (1230) may be disposed on the second housing (1220). The display (1230) may be movable relative to the first housing (1210) by movement of the second housing (1220) relative to the first housing (1210). For example, the display (1230) may be movable from the inside of the first housing (1210) to the outside of the first housing (1210) by movement of the second housing (1220) in the first direction (d1). For example, in a slide-out state of the electronic device (101), the size of the electronic device (101) exposed to the outside of the first housing (1210) may be maximum. For example, the display (1230) can be moved from the outside of the first housing (1210) to the inside of the first housing (1210) by movement of the second housing (1220) in the second direction (d2). For example, the display (1230) can be rolled into the inside of the first housing (1210) from the outside of the first housing (1210) by movement of the second housing (1220) in the second direction (d2).

[0193] According to one embodiment, the first planar portion (1231) may be disposed on the second housing (1220). The shape of the first planar portion (1231) may be maintained independently of the movement of the second housing (1220) with respect to the first housing (1210). The first planar portion (1231) may not be deformed by the movement of the second housing (1220) with respect to the first housing (1210). The first planar portion (1231) may be exposed to the outside of the first housing (1210) independently of the movement of the second housing (1220) with respect to the first housing (1210).

[0194] According to one embodiment, the second planar portion (1232) can be connected to the first planar portion (1231) by a folding portion. The second planar portion (1232) can be spaced apart from the first planar portion (1231). The second planar portion (1232) can be positioned (or accommodated) inside the first housing (1210) and the second housing (1220) within the slide-in state of the electronic device (101). At least a portion of the second planar portion (1232) can be positioned (or exposed) outside the first housing (1210) and the second housing (1220) within the slide-out state of the electronic device (101).

[0195] According to one embodiment, the folding portion may be disposed between the first flat portion (1231) and the second flat portion (1232). The shape of at least a portion of the folding portion may change depending on a change in the state of the electronic device (101). For example, at least a portion of the folding portion may be pulled outward from the first housing (1210) by movement of the second housing (1220) with respect to the first housing (1210) in the first direction (d1). At least a portion of the folding portion may have a shape that is substantially parallel to the first flat portion (1231) by being pulled outward from the first housing (1210). For example, at least a portion of the folding portion may be rolled into the interior of the first housing (1210) by movement of the second housing (1220) with respect to the first housing (1210) in the second direction (d2). At least a portion of the folding portion may have a curved shape relative to the first flat portion (1231) by being rolled into the interior of the first housing (1210).

[0196] According to one embodiment, within the slide-in state of the electronic device (101), the size of the display area of ​​the externally visible display (1230) may be minimum. For example, within the slide-in state of the electronic device (101), only the first flat portion (1231) may be exposed. The position of the second housing (1220) relative to the first housing (1210) while the electronic device (101) is in the slide-in state may be referred to as the reduced position. Within the slide-out state of the electronic device (101), the size of the display area of ​​the externally visible display (1230) may be maximum. For example, within the slide-out state of the electronic device (101), at least a portion of the first flat portion (1231), the folding portion, and the second flat portion (1232) may be exposed. However, the present invention is not limited thereto. For example, within the slide-out state of the electronic device (101), the second flat portion (1232) may not be exposed to the outside of the first housing (1210). The position of the second housing (1220) relative to the first housing (1210) while the electronic device (101) is in the slide-out state may be referred to as the extended position.

[0197] For example, the display driving circuit (221) can adjust color data of a portion of an image to be displayed in first pixels (e.g., first pixels (310) of FIG. 3 or first pixels (510) of FIG. 5) or second pixels (e.g., second pixels (320) of FIG. 3 or second pixels (520) of FIG. 5) within a portion of the display area of ​​the display (1230) while the state of the electronic device (101) changes from the slide-in state to the slide-out state (or from the slide-out state to the slide-in state). For adjusting the color data, each of a first correction value to be applied to the first pixels (e.g., first correction value (731) of FIG. 7B) and a second correction value to be applied to the second pixels (e.g., second correction value (732) of FIG. 7B)) can be adjusted based on a size of the display area of ​​the display (1230). For example, as the size of the display area changes, the number of subpixels connected to one line (e.g., one gate line to which subpixels are connected or one data line to which subpixels are connected) may change, thereby changing the current provided through the one line. To adjust the change in the current, each of the first correction value and the second correction value may be adjusted based on the change in the size of the display area of ​​the display (1230). As a non-limiting example, the first correction value in the slide-in state may be different from the first correction value in the slide-out state. As a non-limiting example, the second correction value in the slide-in state may be different from the second correction value in the slide-out state.

[0198] For example, while the state of the electronic device (101) changes from the slide-in state to the slide-out state, the display area of ​​the display (1230) may include an extended area of ​​the display area whose size changes and a fixed area of ​​the display area whose size is maintained (or an area different from the extended area). As a non-limiting example, the display driving circuit (221) may perform adjustment of color data of a portion of an image corresponding to the first pixels or the second pixels of the extended area. As a non-limiting example, the display driving circuit (221) may perform adjustment of color data of a portion of an image corresponding to the first pixels or the second pixels of the fixed area. Accordingly, the colors of the extended area and the fixed area may be adjusted uniformly (or identically).

[0199] Figures 13a and 13b illustrate examples of exemplary foldable electronic devices.

[0200] FIG. 13A illustrates an unfolded state of an exemplary electronic device according to one embodiment. FIG. 13B illustrates a folded state of an exemplary electronic device according to one embodiment. The electronic device (101) of FIGS. 13A and 13B may be referred to as a foldable electronic device. The electronic device (101) of FIGS. 13A and 13B may be an example of the electronic device (101) of FIG. 1 or the electronic device (101) of FIG. 2. For example, the display (1330) of FIGS. 13A and 13B may include the display panel (160) of the electronic device (101).

[0201] Referring to FIGS. 13A and 13B , an electronic device (101) according to one embodiment may include a first housing (1310), a second housing (1320), and / or a folding housing (1335). For example, the first housing (1310) may be referred to as a first housing part. For example, the second housing (1320) may be referred to as a second housing part. For example, the folding housing (1335) may be referred to as a hinge structure.

[0202] In one embodiment, the display (1330) can be disposed on the first housing (1310) and the second housing (1320) across the folding housing (1335). The display (1330) can be disposed on the first side (1331) and the second side (1332) across the folding housing (1335). For example, an area of ​​the display (1330) disposed on the first side (1331) can be referred to as a first display part or a first area. For example, an area of ​​the display (1330) disposed on the second side (1332) can be referred to as a second display part or a second area. For example, the display (1330) can include a bending area (or a third display part, bending part) that can be bent between the first area and the second area. For example, the bending area may represent an area of ​​the display (1330) corresponding to the folding housing (1335).

[0203] For example, referring to FIG. 13A, the electronic device (101) may be in an unfolded state in which the first housing (1310) and the second housing (1320) are fully folded out by the folding housing (the folding housing (1335) of FIG. 13B). According to one embodiment, the unfolded state may mean a state in which a first direction (1341) toward which a first surface (1331) of the first housing (1310) faces corresponds to a second direction (1342) toward which a second surface (1332) of the second housing (1320) faces. For example, in the unfolded state, the first direction (1341) may be substantially parallel to the second direction (1342). For example, in the unfolded state, the first direction (1341) may be identical to the second direction (1342). In one embodiment, the first surface (1331) and the second surface (1332) may form a substantially flat surface within the unfolded state. In one embodiment, the angle (1333) between the first surface (1331) and the second surface (1332) within the unfolded state may be approximately 180 degrees. In one embodiment, the unfolded state may refer to a state in which the entire display area of ​​the display (1330) may be provided on a substantially flat surface. For example, within the unfolded state, the display area of ​​the display (1330) may not include a curved surface. The unfolded state may be referred to as an outspread state or an outspreading state.

[0204] For example, referring to FIG. 13B, the electronic device (101) may provide a folded state in which the first housing (1310) and the second housing (1320) are folded in by the folding housing (1335). According to one embodiment, the folded state may mean a state in which a first direction (1341) toward which the first surface (1331) (not shown in FIG. 13B) faces is distinguished from a second direction (1342) toward which the second surface (1332) (not shown in FIG. 13B) faces. For example, in the folded state, the angle between the first direction (1341) and the second direction (1342) is substantially approximately 180 degrees, and the first direction (1341) and the second direction (1342) may be distinguished from each other. For example, in a folded state, the angle (1357) between the first side (1331) and the second side (1332) may be substantially 0 degrees. The folded state may be referred to as a folded state. For example, the electronic device (101) may provide a folded state in which the display area (not shown in FIG. 13B) corresponding to the first side (1331) and the second side (1332) are made to face each other by the folding housing (1335), so that the display area (not shown in FIG. 13B) corresponding to the second side (1332) substantially completely overlaps the display area (not shown in FIG. 13B) of the display (1330). For example, the electronic device (101) may provide a folded state in which the first direction (1341) is substantially opposite to the second direction (1342). As another example, the folding state may mean a state in which the display area of ​​the display (1330) is hidden from the view of a user looking at the electronic device (101), but is not limited thereto.

[0205] According to one embodiment, the display (1330) may be bent by rotation provided through the folding housing (1335). For example, within the folded state, a portion of the display area of ​​the display (1330) may be bent. For example, the portion of the display area of ​​the display (1330) may be in a curved state to prevent damage to the display (1330) within the folded state. However, the present invention is not limited thereto.

[0206] For example, the processor (130) can identify an angle between a first direction (1341) toward which a first surface (1331) of the first housing (1310) faces and a second direction (1342) toward which a second surface (1332) of the second housing (1320) faces, through a Hall sensor within the electronic device (101), a rotation sensor within the folding housing (1335), and / or a stretch sensor within the electronic device (101).

[0207] Meanwhile, the first housing (1310) may include a display (1350), which is a cover display, on a third side (1355) opposite to the first side (1331). For example, the display (1350) may be used to provide visual information within the folded state in which the display area (e.g., the first area, the second area, the bending area) of the display (1330) is not visible.

[0208] For example, the display driving circuit (221) may adjust color data of a portion of an image to be displayed in first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) or second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) within a portion of the display area of ​​the display (1330) while the state of the electronic device (101) changes from the folded state to the unfolded state (or from the unfolded state to the folded state). For example, while the state of the electronic device (101) changes from the unfolded state to the folded state, the display area of ​​the display (1330) may include the bending area of ​​the display (1330) and the first area and the second area of ​​the display (1330). As a non-limiting example, the display driving circuit (221) can adjust color data of a portion of an image corresponding to first pixels or second pixels of the bending area. As a non-limiting example, the display driving circuit (221) can adjust color data of a portion of an image corresponding to first pixels or second pixels of the first area. As a non-limiting example, the display driving circuit (221) can adjust color data of a portion of an image corresponding to first pixels or second pixels of the second area. Accordingly, the colors of the first area, the second area, and the bending area can be adjusted uniformly (or identically).

[0209] In order to adjust the color data, each of a first correction value to be applied to the first pixels (e.g., the first correction value (731) of FIG. 7B) and a second correction value to be applied to the second pixels (e.g., the second correction value (732) of FIG. 7B) may be adjusted based on the size of the display area of ​​the display (1330). For example, as the size of the display area changes, the number of sub-pixels connected to one line (e.g., one gate line to which sub-pixels are connected or one data line to which sub-pixels are connected) may change, thereby changing the current provided through the one line. In order to adjust the change in the current, each of the first correction value and the second correction value may be adjusted based on the change in the size of the display area of ​​the display (1330). As a non-limiting example, the first correction value in the unfolded state may be different from the first correction value in the folded state. As a non-limiting example, the second correction value within the unfolded state may be different from the second correction value within the folded state.

[0210] As a non-limiting example, the state of the electronic device (101) of FIGS. 13A and 13B may be an intermediate state between the folded state and the unfolded state. For example, the intermediate state may include a case where the angle (1333) is approximately 90°. For example, the intermediate state may be referred to as a flex mode. Within the intermediate state, the first region may be positioned relatively parallel to a direction of gaze of a user of the electronic device (101). At this time, within the intermediate state, the second region may be positioned relatively perpendicular to the direction of gaze of the user by being placed in contact with an external object. At this time, the electronic device (101) may apply the privacy display mode to the first region and apply the normal display mode to the second region. The display driving circuit (221) may independently perform adjustment for color uniformity with respect to pixels of the first region or the second region to reduce a color difference between the first region and the second region. At least one processor (210) can identify correction values ​​for adjusting for color uniformity according to an angle (1333). For example, in order to reduce color differences that may change according to an angle (1333), at least one processor (210) can identify correction values ​​considering the angle (1333). At least one processor (210) can identify correction values ​​for adjusting for color uniformity according to a user's gaze direction. For example, in order to reduce color differences that may change according to a user's gaze direction, at least one processor (210) can identify correction values ​​considering sensing data for the gaze direction. For example, the sensing data can be acquired using at least one sensor included in the electronic device (101).

[0211] Figure 14 illustrates an example of an exemplary multi-foldable electronic device.

[0212] Referring to FIG. 14, an electronic device (101) which is a multi-foldable electronic device of the first type (1400a) and an electronic device (101) which is a multi-foldable electronic device of the second type (1400b) are illustrated. The electronic device (101) of FIG. 14 may represent an example of the electronic device (101) of FIG. 1 or the electronic device (101) of FIG. 2. For example, the display (1430) of FIG. 14 may include a display panel (160) of the electronic device (101).

[0213] For example, in the electronic device (101) of the first type (1400a), when the display (1430) is in a folded state (or a folding state), when viewed from one side of the electronic device (101), the housing (1410) of the electronic device (101) may have a G (or P) shape. In contrast, in the electronic device (101) of the second type (1400b), when the display (1430) is in a folded state (or a folding state), when viewed from one side of the electronic device (101), the housing (1410) of the electronic device (101) may have a Z shape.

[0214] Referring to FIG. 14, the electronic device (101) may include a first housing (1411), a second housing (1412), a third housing (1413), a first hinge structure, a second hinge structure, and a display (1430). The first housing (1411) may be rotatably coupled to the second housing (1412) via the first hinge structure. For example, the first housing (1411) and the second housing (1412) may rotate about the first folding axis via the first hinge structure disposed along the first folding axis. The third housing (1413) may be rotatably coupled to the second housing (1412) via the second hinge structure. For example, the second housing (1412) and the third housing (1413) can rotate about the second folding axis through a second hinge structure arranged along the second folding axis.

[0215] The display (1430) may form at least a portion of the exterior of the electronic device (101). The display (1430) may be partially disposed within the first housing (1411), the second housing (1412), and the third housing (1413). The display (1430) may define the front of the electronic device (101) by forming one side of the first housing (1411), one side of the second housing (1412), and one side of the third housing (1413). The display (1430) may include an area where a front camera is positioned. The area of ​​the display (1430) may include an opening for the front camera. However, the present invention is not limited thereto, and the front camera may be disposed below an area corresponding to the area of ​​the display (1430). The display (1430) can provide visual information to the user through the above area, and the front camera can obtain an image of an external object located in a direction facing the front of the electronic device (101) through the above area of ​​the display (1430).

[0216] The display (1430) may include a first planar portion, a second planar portion, a third planar portion, a first deformable portion, and a second deformable portion. The first planar portion of the display (1430) may be disposed on one surface of the first housing (1411). The second planar portion of the display (1430) may be disposed on one surface of the second housing (1412). The third planar portion of the display (1430) may be disposed on one surface of the third housing (1413). The first deformable portion of the display (1430) may be located between the first planar portion of the display (1430) and the second planar portion of the display (1430). For example, the first deformable portion of the display (1430) may be disposed on a first hinge structure connecting the first housing (1411) and the second housing (1412). The second deformable portion of the display (1430) may be disposed between the second planar portion of the display (1430) and the third planar portion of the display (1430). For example, the second deformable portion may be disposed on a second hinge structure connecting the second housing (1412) and the third housing (1413).

[0217] For example, a first display area (1431) of a display (1430) may include at least a portion of a first deformable portion and a first planar portion. For example, a second display area (1432) of a display (1430) may include a second planar portion, at least a portion of a first deformable portion, and at least a portion of a second deformable portion. For example, a third display area (1433) of a display (1430) may include at least a portion of a second deformable portion and a third planar portion.

[0218] The first planar portion, the second planar portion, and the third planar portion of the display (1430) can maintain a plane regardless of the state of the electronic device (101). The first deformable portion and the second deformable portion of the display (1430) can unfold or bend depending on the state of the electronic device (101).

[0219] The additional display (or cover display), the first rear cover, and the second rear cover may form at least a portion of the exterior of the electronic device (101). The first rear cover may form another side of the first housing (1411), the cover display may form another side of the second housing (1412), and the second rear cover may be formed on another side of the third housing (1413). The cover display, the first rear cover, and the second rear cover may define the rear side of the electronic device (101). The first rear cover may include a structure (e.g., an opening) for exposing a rear camera disposed within the first housing (1411). The cover display may include an area where another front camera is positioned. The area of ​​the cover display may include an opening for the front camera.

[0220] For example, the display driving circuit (221) may adjust color data of a portion of an image to be displayed in first pixels (e.g., first pixels (310) of FIG. 3 or first pixels (510) of FIG. 5) or second pixels (e.g., second pixels (320) of FIG. 3 or second pixels (520) of FIG. 5) within a portion of the display area of ​​the display (1430) while the state of the electronic device (101) changes from the folded state to the unfolded state (or from the unfolded state to the folded state). For example, the folded state may indicate a state in which the size of the display area of ​​the display (1430) is the smallest, and the unfolded state may indicate a state in which the size of the display area of ​​the display (1430) is the largest. As a non-limiting example, the display driving circuit (221) may perform adjustment of color data of a portion of an image corresponding to first pixels or second pixels of the display area.

[0221] In order to adjust the color data, each of a first correction value to be applied to the first pixels (e.g., the first correction value (731) of FIG. 7B) and a second correction value to be applied to the second pixels (e.g., the second correction value (732) of FIG. 7B) may be adjusted based on the size of the display area of ​​the display (1430). For example, as the size of the display area changes, the number of sub-pixels connected to one line (e.g., one gate line to which sub-pixels are connected or one data line to which sub-pixels are connected) may change, thereby changing the current provided through the one line. In order to adjust the change in the current, each of the first correction value and the second correction value may be adjusted based on the change in the size of the display area of ​​the display (1430). As a non-limiting example, the first correction value in the unfolded state may be different from the first correction value in the folded state. As a non-limiting example, the second correction value within the unfolded state may be different from the second correction value within the folded state.

[0222] As a non-limiting example, the display driving circuit (221) may adjust color data of a portion of an image corresponding to first pixels or second pixels in a portion of the display area of ​​the display (1430). As a non-limiting example, the display driving circuit (221) may adjust color data of a portion of an image corresponding to first pixels or second pixels in a remaining area of ​​the display area of ​​the display (1430). Accordingly, colors within the display area of ​​the display (1430) may be adjusted uniformly (or identically).

[0223] Referring to FIGS. 1 to 14, an example of adjusting color data of a portion of an image to be displayed through each of the first pixels and the second pixels distinguished according to FOI among all pixels of the display panel (160) is described, but the present disclosure is not limited thereto. For example, even when the privacy display mode is applied to some pixels located within a specific area among all pixels, the same may be applied substantially. For example, the function of displaying an image through some pixels located within the specific area of ​​the display panel (160) may be referred to as a partial function. Within the partial function, a first image may be displayed within the specific area of ​​the display panel (160), and a second image may be displayed within the remaining area of ​​the display panel (160). The electronic device (101) may activate (or apply) the privacy display mode within the specific area, and activate (or apply) the normal display mode within the remaining area.

[0224] In the above example, in order to reduce the color difference and the luminance difference between the specific region and the remaining region, the color data of a portion of the image to be displayed in the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) or the second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) within the specific region can be independently adjusted. Alternatively, in order to reduce the color difference and the luminance difference between the specific region and the remaining region, the color data of a portion of the image to be displayed in the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) or the second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) within the specific region can be independently adjusted.

[0225] Some of the operations described above may be executed (or performed) by an artificial intelligence (AI) system as described with reference to FIG. 15. For example, the AI ​​system (or trained model (215)) may be used to adjust the intensity of the privacy display mode based on one or more contents provided within an image displayed on the display panel (160). For example, the intensity of the privacy display mode may be determined based on a ratio of light emission of the first pixels among the first pixels (e.g., the first pixels (310) of FIG. 3 or the first pixels (510) of FIG. 5) and the second pixels (e.g., the second pixels (320) of FIG. 3 or the second pixels (520) of FIG. 5) of the display panel (160). Alternatively, for example, the intensity of the privacy display mode may be determined by adjusting color data to be applied to first pixels (e.g., first pixels (310) of FIG. 3 or first pixels (510) of FIG. 5) and adjusting color data to be applied to second pixels (e.g., second pixels (320) of FIG. 3 or second pixels (520) of FIG. 5). For example, the AI ​​system (or trained model (215)) may determine (or adjust, change, manage) activation of the privacy display mode, an area to which the privacy display mode is to be applied, or the intensity of the privacy display mode, depending on the one or more contents in the image.

[0226] Figure 15 is a schematic diagram of an exemplary AI (artificial intelligence) system.

[0227] Referring to FIG. 15, the AI ​​system (1500) may include an input / output interface (1510), an AI (artificial intelligence) framework (1520), a generative AI model (1530), an application / service component (1580), and / or a knowledge repository (1590).

[0228] The input / output interface (1510) can receive input. The input can include user input and / or data acquired or generated by an electronic device (e.g., the electronic device (101) or the electronic device (1301) 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 (1320)) of the electronic device (e.g., illuminance data around the electronic device acquired from a sensor or sensor hub (e.g., a coprocessor (1323), 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 (1380)) 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 (1510) 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 (1510).

[0229] The input / output interface (1510) can transmit (or provide) output. The output may include a result (or result information) generated or obtained by the AI ​​system (1500) 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.

[0230] The input / output interface (1510) can be described as a user query / response interface (1510).

[0231] The AI ​​framework (1520) can be used to obtain information (or data) about the input from the input / output interface (1510) and control one or more components related to the AI ​​system (1500) using the obtained information.

[0232] For example, the prompt design component (1521) within the AI ​​framework (1520) can use the acquired information to generate or obtain prompts for a generative AI model (1530) (e.g., including a large language model (LLM) or a large multimodal model (LMM)). For example, the prompt design component (1521) can be described as an AI component that utilizes a learning algorithm and / or a neural network to provide enhanced prompts over time. For example, the prompt design component (1521) can use the acquired information to access a knowledge component (e.g., a knowledge repository (1590)) that includes user preference data, a prompt library, and / or prompt examples to generate or obtain prompts. The generated prompts can be provided to the generative AI model (1530) (e.g., including an LLM or LMM).

[0233] For example, the API / plugin management component (1522) within the AI ​​framework (1520) may be utilized to facilitate communication for additional information requested (or induced) in connection with the prompt provided (or to be provided) to the generative AI model (1530). For example, the API / plugin management component (1522) may be utilized to create or establish channels for communication with various data sources (e.g., knowledge repositories (1590)). For example, the API / plugin management component (1522) may facilitate access to at least some of the data sources. For example, the API / plugin management component (1522) may be utilized to request another component (e.g., an application / service component (1580)) to perform feedback (or response) in response to the prompt. As a non-limiting example, information obtained (or generated) through the API / plugin management component (1522) may be provided to the prompt design component (1521) for generating a prompt. As a non-limiting example, information obtained (or generated) through the API / plugin management component (1522) may be provided to the generative AI model (1530).

[0234] For example, the improvement component (1523) within the AI ​​framework (1520) can at least partially tune (or adjust) (or change) the result (e.g., content) obtained (or output) from the generative AI model (1530). For example, the improvement component (1523) can determine or verify whether the content obtained from the generative AI model (1530) is relevant to the input. For example, the improvement component (1523) can determine or verify whether the content obtained from the generative AI model (1530) contains biased content. For example, the improvement component (1523) can determine or verify whether the content obtained from the generative AI model (1530) contains harmful content. For example, the improvement component (1523) can support or assist in performing additional processing to improve the content obtained from the generative AI model (1530). For example, the improvement component (1523) may support providing hints to the user to improve the content.

[0235] A generative AI model (1530) 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 (1530) 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 (1530) may include an LMM that generates the feedback by recognizing text, images, and / or speech.

[0236] As a non-limiting example, the AI ​​framework (1520) and / or the generative AI model (1530) 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 (1320)). 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 (1430)). 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.

[0237] The present disclosure can adjust the color data of an image by using different correction values ​​(e.g., a first correction value (731) and a second correction value (732)) instead of using the same correction value (e.g., a correction value (730)) for pixels having different FOIs (e.g., a first pixel (710) and a second pixel (720)). Accordingly, the present disclosure can reduce the color difference between parts of an image displayed through pixels of a display panel (160).

[0238] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

[0239] As described above, the electronic device (101) may include at least one processor (210) including a processing circuit. The electronic device (101) may include a display panel (160). The display panel (160) may include a first layer including a black matrix (BM) defining first light-transmitting portions and second light-transmitting portions smaller than the first light-transmitting portions. The display panel (160) may include a second layer disposed under the first layer. The second layer may include first sub-pixels disposed under each of the first light-transmitting portions and configured to emit light, and second sub-pixels disposed under each of the second light-transmitting portions and configured to emit light. A viewing angle according to the second sub-pixels and the second light-transmitting portions may be narrower than a viewing angle according to the first light-transmitting portions and the first sub-pixels. The electronic device (101) may include a display driving circuit (221). The display driving circuit (221) may be configured to receive, from the at least one processor (210), an image including a first portion corresponding to the first sub-pixels and a second portion corresponding to the second sub-pixels. First color data of the first portion of the image may correspond to second color data of the second portion of the image. The display driving circuit (221) may be configured to adjust the first color data of the first portion of the image to third color data. The display driving circuit (221) may be configured to adjust the second color data of the second portion of the image to fourth color data different from the third color data.The display driving circuit (221) may be configured to display the image on the display area of ​​the display panel (160) based on the third color data and the fourth color data. The color of the first part of the image displayed on the display area and the color of the second part of the image displayed on the display area may appear identical.

[0240] According to one embodiment, the display driving circuit (221) may be configured to receive, from the at least one processor (210), a first correction value for adjusting the first color data to the third color data and a second correction value for adjusting the second color data to the fourth color data. The display driving circuit (221) may be configured to independently perform a first adjustment from the first color data of the first portion of the image to the third color data using the first correction value and a second adjustment from the second color data of the second portion of the image to the fourth color data using the second correction value, for color uniformity.

[0241] According to one embodiment, the first correction value may include a first grayscale level for a first color, a second grayscale level for a second color, and a third grayscale level for a third color. The second correction value may include a fourth grayscale level for the first color, a fifth grayscale level for the second color, and a sixth grayscale level for the third color. The first correction value may be at least partially different from the second correction value.

[0242] According to one embodiment, the electronic device (101) may include a memory that stores one or more programs configured to be individually and / or collectively executed by the at least one processor (210), and includes one or more storage media. The one or more programs may include instructions that cause the electronic device (101) to obtain information about color coordinates representing a reference color displayed through the first sub-pixels among the first sub-pixels and the second sub-pixels, stored in the display driving circuit (221). The one or more programs may include instructions that cause the electronic device (101) to identify a first reference color coordinate within a color gamut representing the reference color and a second reference color coordinate within the color gamut representing the reference color. The one or more programs may include instructions that cause the electronic device (101) to identify the first correction value for moving the color coordinates to the first reference color coordinates using at least some of the second reference color coordinates and the first reference color coordinates.

[0243] According to one embodiment, the first reference color coordinates may be located at the center of the color region representing the reference color. The second reference color coordinates may be located at the edge of the color region representing the reference color.

[0244] According to one embodiment, the one or more programs may include instructions that cause the electronic device (101) to identify color gamut portions of the color gamut representing the reference color according to the first reference color coordinates and the second reference color coordinates.
