AI Technical Summary
Existing display panels lack the ability to effectively control viewing angles, particularly in scenarios requiring privacy, leading to potential unauthorized viewing of displayed information.
A display panel design featuring alternating groups of larger and smaller light-transmitting portions, combined with specific refractive index layers and dielectric/insulating edges, allows for narrower viewing angles while maintaining brightness and extending the lifespan of light-emitting elements.
The solution provides enhanced privacy by reducing the angle at which information can be viewed from the sides, while maintaining brightness and extending the life of the display panel components.

[0022] Figure 1 is a schematic view of an exemplary electronic device.
[0023] Referring to FIG. 1, the electronic device (100) may include at least one processor (110) including a processing circuit, a display (120), and a memory (130). The electronic device (100) may include at least a portion of the electronic device (2601) of FIG. 26 or may correspond to at least a portion of the electronic device (2601) of FIG. 26.
[0024] At least one processor (110) may include at least a portion of the processor (2620) of FIG. 26 or may correspond to at least a portion of the processor (2620) of FIG. 26. The at least one processor (110) may include a central processing unit (CPU) (111) (e.g., including a processing circuit) and a display processing unit (DPU) (112) (e.g., including a processing circuit). As a non-limiting example, the at least one processor (110) may further include a graphics processing unit (GPU) (e.g., including a processing circuit). The at least one processor (110) may be configured to execute instructions stored in the memory (130).
[0025] At least one processor (110) may cause the electronic device (100) to perform operations for the normal display mode described below based on executing the instructions. At least one processor (110) may cause the electronic device (100) to perform operations for the privacy display mode (or private display mode) described below based on executing the instructions.
[0026] The display (120) may include at least a portion of the display module (2660) of FIG. 26 or may correspond to at least a portion of the display module (2660) of FIG. 26. The display (120) may include a display driver circuitry (or display driver integrated circuitry) (140) and a display panel (160).
[0027] The display driver circuit (140) may include at least a portion of the display driver IC (2730) of FIG. 27 or correspond to at least a portion of the display driver IC (2730) of FIG. 27. For example, the display driver circuit (140) may control the display panel (160) to display a screen having at least a portion of a first viewing angle (e.g., within a first angle range) based on one or more commands from at least one processor (110). For example, the screen displayed on the display panel (160) may at least partially have the first viewing angle according to the normal display mode. For example, the display driver circuit (140) may control the display panel (160) to display a screen having at least a portion of a second viewing angle (e.g., within a second angle range) narrower than the first viewing angle, based on one or more commands from at least one processor (110). For example, the screen displayed on the display panel (160) may at least partially have the second viewing angle depending on the privacy display mode.
[0028] The display panel (160) may include at least a portion of the display (2710) of FIG. 27 or may correspond to at least a portion of the display (2710) of FIG. 27. The display panel (160) may include the structure illustrated in FIG. 4. The display panel (160) may include the structure illustrated in one of FIG. 5, FIG. 7, and FIG. 9 to FIG. 25.
[0029] The display (120) may operate or be driven for command mode, video mode, hybrid video mode, and / or adaptive refresh panel (ARP) of MIPI (mobile industry processor interface) DSI (display serial interface).
[0030] The memory (130) may include one or more storage media. For example, the one or more storage media may include a hard drive, flash memory, permanent memory such as read-only memory (ROM), semi-permanent memory such as random access memory (RAM), any other suitable type of storage assembly, or any combination thereof. The memory (130) may include a cache memory, which is one or more different types of memory used to temporarily store data for the function or feature of the electronic device (100). The memory (130) may be fixedly embedded within the electronic device (100) or incorporated into one or more suitable types of components (e.g., a subscriber identity module (SIM) card and / or a secure digital (SD) memory card) that can be repeatedly inserted into and removed from the electronic device (100). For example, the memory (130) may include at least a portion of the memory (2630) of FIG. 26 or correspond to at least a portion of the memory (2630) of FIG. 26.
[0031] The memory (130) may store one or more software applications, such as an operating system software application, a firmware software application, a media playback software application, a media editing software application, a software application for communicating with other users, a translation software application, a digital assistant software application, and / or any other suitable software applications. For example, the one or more software applications may include instructions executable by at least a portion of at least one processor (110).
[0032] Figure 2 illustrates an example of changing the viewing angle of a screen displayed on a display panel.
[0033] Referring to FIG. 2, the display driving circuit (140) can display a screen (210) on a display panel (160). The screen (210) can include one or more contents (or one or more media contents). The screen (210) can include one or more visual objects. The screen (210) can be displayed on the display panel (160) to provide information.
[0034] The display driving circuit (140) can display a screen (210) having a viewing angle (281) on the display panel (160). For example, the viewing angle (281) of the screen (210) can be wider than the viewing angle (282) of the screen (210) described below. For example, the screen (210) having the viewing angle (281) can be displayed on the display panel (160) according to the normal display mode. For example, the viewing angle (281) can be wider than a critical viewing angle.
[0035] The electronic device (100) may provide a function (or feature) for user privacy with respect to the display on the display panel (160). For example, the electronic device (100) may provide a privacy display mode that narrows the viewing angle of at least a portion of the screen (210) displayed on the display panel (160) for the above function. For example, the privacy display mode may be described as a display mode for reducing the probability that information within the screen (e.g., screen (210)) displayed on the display panel (160) will be visible to another user who is distinct from the user of the electronic device (100). For example, the privacy display mode may be described as a display mode for reducing the probability that information within the screen displayed on the display panel (160) will be visible from a second space around a first space in front of the display panel (160). For example, the privacy display mode may be described as a display mode for reducing visibility from the second space. For example, the display driving circuit (140) can display a screen (210) having a viewing angle (282) (e.g., narrower than or equal to the critical viewing angle) on the display panel (160) according to the privacy display mode. The privacy display mode can be changed or switched from the normal display mode. For example, the display driving circuit (140) can change the display of the screen (210) having a viewing angle (281) to the display of the screen (210) having a viewing angle (282) based on the privacy display mode changed from the normal display mode.For example, the display driving circuit (140) can stop (or terminate) (or deactivate) displaying a screen (210) having a viewing angle (281) and display a screen (210) having a viewing angle (282) based on changing the normal display mode to the first privacy display mode.
[0036] 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. For example, as described below, the display panel (160) may include a first layer (e.g., the first layer (501) of FIGS. 5 and 7) 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. Depending on the configuration example or embodiment, the first light-transmitting portions may be smaller than the second light-transmitting portions. The display panel (160) may include a second layer (e.g., the second layer (502) of FIGS. 5 and 7) disposed below the first layer and 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.
[0037] For example, the display panel (160) may include a first pixel including light-emitting elements within the second layer disposed below each of the first light-transmitting portions. For example, the first pixel may include sub-pixels. The sub-pixels 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 sub-pixels within the first pixel may include transistors configured to control the light-emitting elements included within each of the sub-pixels within the first pixel.
[0038] 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. 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.
[0039] 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.
[0040] As a non-limiting example, the display driving circuit (140) may control the display panel (160) to emit light through the first pixel and emit light through the second pixel in order to perform (or execute) a display on the display panel (160) according to the normal display mode. As a non-limiting example, even if a grayscale value provided from at least one processor (110) in relation to the first pixel and a grayscale value provided from at least one processor (110) in relation to the second pixel are the same, a first voltage (or a first current) applied from the display driving circuit (140) to the first pixel may be higher than a second voltage (or a second current) applied from the display driving circuit (140) to the second pixel. For example, the first voltage (or the first current) higher than the second voltage (or the second current) may be applied by adjusting a driving voltage (e.g., ELVDD and / or ELVSS) with respect to the first pixel. For example, the first voltage (or the first current) higher than the second voltage (or the second current) may be applied by adjusting a data voltage (e.g., Vdata) with respect to the first pixel. For example, the first voltage (or the first current) higher than the second voltage (or the second current) may be applied by adjusting a thin film transistor (TFT) for the first pixel that is different in size from a TFT for the second pixel. For example, the first voltage (or the first current) higher than the second voltage (or the second current) may be applied according to a capacitance of the capacitor for the first pixel that is different from the capacitance of the capacitor for the second pixel.
[0041] As a non-limiting example, the display driving circuit (140) may control the display panel (160) to refrain from emitting light through the first pixel and to emit light through the second pixel in order to perform (or execute) a display on the display panel (160) according to the privacy display mode. For example, since the second pixel is used for both the normal display mode and the privacy display mode, relative to the first pixel used for the normal display mode, the lifespan of the light-emitting elements within the second pixel may be shorter than the lifespan of the light-emitting elements within the first pixel. For example, a structure for reducing the current provided to the light-emitting elements within the second pixel while maintaining the brightness provided by the second pixel may be included in the display panel (160) in order to prolong the lifespan of the light-emitting elements within the second pixel.
[0042] As a non-limiting example, since the display panel (160) includes the second pixel, the position range in which information within the screen displayed on the display panel (160) can be recognized according to the normal display mode may be narrower than the position range in which information within the screen displayed on the display panel that includes only the first pixel can be recognized. The position range in which information within the screen displayed on the display panel (160) can be recognized according to the normal display mode is described with reference to FIG. 3.
[0043] Figure 3 is a chart showing the distribution of luminance by observation position provided according to the normal display mode.
[0044] Referring to FIG. 3, the horizontal axis of the chart (300) represents an angle. The angle can be described as the angle between the position for observing the screen displayed on the display panel (160) and the direction of the display panel (160) (or the display area). The vertical axis of the chart (300) represents brightness. For example, a brightness of 1 represents the highest brightness, and a brightness of 0.8 represents a brightness that is 20 (%) (percent) lower than the highest brightness.
[0045] A line (301) in the chart (300) represents the distribution of the luminance of light emitted through the first pixel by observation position. A line (302) in the chart (300) represents the distribution of the luminance of light emitted through the second pixel by observation position.
[0046] A line (303) in the chart (300) represents the distribution of the luminance of light emitted through the first pixel and the second pixel for displaying a screen on the display panel (160) according to the normal display mode, according to each observation position. As a non-limiting example, the number of the first pixels in the display panel (160) may be the same as the number of the second pixels in the display panel (160). For example, when the number of the first pixels in the display panel (160) is the same as the number of the second pixels in the display panel (160), the line (303) represents the average luminance of the luminance represented by the line (301) and the luminance represented by the line (302).
[0047] As a non-limiting example, unlike the display panel (160) including both the first pixel and the second pixel, another display panel including only the first pixel may emit light in a distribution represented by the line (301). For example, as represented by the lines (301) and (303), a position range in which information within a screen displayed on the display panel (160) including both the first pixel and the second pixel may be recognizable according to the normal display mode may be narrower than a position range in which information within a screen displayed on the display panel including only the first pixel may be recognizable. Since the position range provided by the display panel (160) being narrower than the position range provided by the other display panel may reduce the quality of service of the display (120), the display panel (160) may include an (additional) structure for widening the position range in which information within a screen displayed on the display panel (160) may be recognizable. For example, the display panel (160) may include a structure for narrowing the difference (305) between the line (301) and the line (303).
[0048] The display panel (160) described below may include a structure for maintaining the brightness provided by the second pixel while reducing the current provided to the light-emitting elements within the second pixel and / or a structure for expanding the range of positions where information within the screen displayed within the normal display mode can be recognized.
[0049] Figure 4 illustrates an example of a display panel.
[0050] Referring to FIG. 4, the display panel (160) may include a plurality of pixels. Each of the pixels may include sub-pixels. The sub-pixels may include a first sub-pixel (450-1) including a light-emitting element (or light-emitting portion) configured to emit light in a first color (e.g., red), a second sub-pixel (450-2) including a light-emitting element (or light-emitting portion) configured to emit light in a second color (e.g., green), and a third sub-pixel (450-3) including a light-emitting element (or light-emitting portion) configured to emit light in a third color (e.g., blue). The sub-pixels may further include a fourth sub-pixel (not shown) including a light-emitting element (or light-emitting portion) configured to emit light in a fourth color (e.g., white).
[0051] The field of illumination (FOI) of light emitted from one or more of the pixels may be narrower than the FOI of light emitted from one or more other of the pixels. For example, the one or more of the pixels may include pixel (421) and pixel (422). For example, the other one or more of the pixels may include pixel (411) and pixel (412).
[0052] For example, one or more of the pixels may be positioned within (or within) a first set (420) of regions within the active area (or display area) of the display panel (160), such as pixels (421) and (422). For example, the other one or more of the pixels may be positioned within (or within) a second set (410) of regions within the active area of the display panel (160), such as pixels (411) and (412). As a non-limiting example, the regions included within the first set (420) of regions and the regions included within the second set (410) of regions may alternate with each other. As a non-limiting example, the regions included within the first set (420) of regions and the regions included within the second set (410) of regions may be included within the active area in an interleaved arrangement.
[0053] The display panel (160) may include an opaque member in a first layer of the display panel (160) disposed on a second layer of the display panel (160) including light-emitting portions, in order to narrow (or reduce) the FOI of light emitted from the one or more of the pixels compared to the FOI of light emitted from the other one or more of the plurality of pixels. The opaque member of the first layer of the display panel (160) may be structured to narrow the viewing angle of at least a portion of a screen (e.g., screen (210)) displayed on the display panel (160). The opaque member of the first layer of the display panel (160) may partially overly the light-emitting elements in the one or more of the pixels, and may not overly the light-emitting elements in the other one or more of the pixels.
[0054] The display panel (160) may include at least one third layer for reducing the current provided to the light-emitting elements within the second pixels (e.g., pixels (421) and (422)) while maintaining the brightness provided by the second pixels and / or expanding the range of positions where information within the screen displayed within the normal display mode can be recognized. The arrangement of the first layer, the second layer, and the at least one layer is described with reference to FIGS. 5, 7, and 9 to 25.
[0055] FIG. 5 is a cross-sectional view of a display panel according to a first example configuration.
[0056] Figure 5 is a cross-sectional view of AB of Figure 4.
[0057] Referring to FIG. 5, the display panel (160) may include a first layer (501) including an opaque member (510). The opaque member (510) of the first layer (501) may be described as a black matrix (510) of the first layer (501). As a non-limiting example, the first layer (501) or the opaque member (510) of the first layer (501) may be included in the display panel (160) for the privacy display mode. The opaque member (510) of the first layer (501) may include the first light-transmitting portions described above, the second light-transmitting portions described above (e.g., smaller than the first light-transmitting portions), a first opaque portion (521) surrounding the first light-transmitting portions, and a second opaque portion (522) surrounding the second light-transmitting portions. For example, the first light-transmitting portions may include a first light-transmitting portion (511). For example, the second light-transmitting portions may include second light-transmitting portions (512) that are smaller than the first light-transmitting portion (511). The first light-transmitting portion (511) may be formed as an opening. The second light-transmitting portions (512) may each be formed as openings. The first opaque portion (521) may define the size and shape of the first light-transmitting portions that include the first light-transmitting portion (511). The second opaque portion (522) may define the size and shape of the second light-transmitting portions that include the second light-transmitting portions (512). The first opaque portion (521) and the second opaque portion (522) may be formed from a material that substantially blocks light.
[0058] The display panel (160) may include a second layer (502) disposed under the first layer (501). The second layer (502) may include first light-emitting portions disposed under each of the first light-transmitting portions of the opaque member (510) of the first layer (501), second light-emitting portions disposed under each of the second light-transmitting portions of the opaque member (510) of the first layer (501), first dielectric portions (541) defining edges of each of the first light-emitting portions of the second layer (502), and second insulating portions (542) defining edges of each of the second light-emitting portions of the second layer (502).
[0059] The first light-emitting portions may include first light-emitting portions (531). The first light-emitting portions may be described as first light-emitting elements. Each of the first light-emitting portions may be included in one sub-pixel. The sub-pixel may further include transistors configured to control each of the first light-emitting portions. The display panel (160) may further include a layer (e.g., a substrate layer) disposed under the second layer (502). The layer disposed under the second layer (502) may be patterned for the transistors configured to control each of the first light-emitting portions. The second light-emitting portions may include second light-emitting portions (532). The second light-emitting portions may be described as second light-emitting elements. Each of the second light-emitting portions may be included in one sub-pixel. The sub-pixel may further include transistors configured to control each of the second light-emitting portions. The layer disposed below the second layer (502) can be patterned for the transistors configured to control each of the second light-emitting portions.
[0060] The first light-emitting portions (531) can overlap with the first light-transmitting portions (511). The first light-transmitting portions (511) can surround the first light-emitting portions (531) when the display panel (160) is viewed from above. The first light-emitting portions (531) can be positioned within the first light-transmitting portions (511) when the display panel (160) is viewed from above. The first light-transmitting portions (511) can overlie the first light-emitting portions (531).
[0061] The second light-transmitting portions (512) can be aligned with the second light-emitting portions (532), respectively. The second light-emitting portions (532) can overlap the second light-transmitting portions (512), respectively. The second light-transmitting portions (512) can surround the second light-emitting portions (532), respectively, when the display panel (160) is viewed from above. The second light-emitting portions (532) can be positioned within the second light-transmitting portions (512), respectively, when the display panel (160) is viewed from above. The second light-transmitting portions (512) can be positioned over the second light-emitting portions (532), respectively. Light emitted from the second light-emitting portions (532) can be partially blocked by the second opaque portion (522).
[0062] As a non-limiting example, the first light-emitting portions (531) may include a first light-emitting portion (531-1) configured to emit light having the third color (e.g., blue), and a first light-emitting portion (531-2) configured to emit light having the second color (e.g., green) different from the third color. As a non-limiting example, the second light-emitting portions (532) may include a second light-emitting portion (532-1) configured to emit light having the third color, and a second light-emitting portion (532-2) configured to emit light having the second color.
[0063] The first insulating portion (541) and the second insulating portion (542) may be described as a pixel definition layer (PDL) included in the second layer (502). The first insulating portion (541) may define the size and shape of the first light-emitting portions including the first light-emitting portions (531). The second insulating portion (542) may define the size and shape of the second light-emitting portions including the second light-emitting portions (532). As a non-limiting example, the size and shape of the first light-emitting portion (531-1) defined by the first insulating portion (541) may correspond to the size and shape of the second light-emitting portion (532-1) defined by the second insulating portion (542), respectively. As a non-limiting example, the size and shape of the first light-emitting portion (531-2) defined by the first insulating portion (541) may correspond to the size and shape of the second light-emitting portion (532-2) defined by the second insulating portion (542), respectively.
[0064] The display panel (160) may include a third layer (503) positioned between the first layer (501) and the second layer (502). The third layer (503) may be included within the display panel (160) to maintain the brightness provided by the second light-emitting portions while reducing the current provided to the second light-emitting portions. The third layer (503) may include a first portion (551) disposed between the second opaque portion (522) of the opaque member (510) of the first layer (501) and the second insulating portion (542) of the second layer (502), and second portions (e.g., second portions (552)) disposed between the second light-transmitting portions (e.g., second light-transmitting portions (512)) of the opaque member (510) of the first layer (501) and the second light-emitting portions (e.g., second light-emitting portions (532)) of the second layer (502). The first portion (551) of the third layer (503) may include a member (or material) having a first refractive index. The second portions (e.g., the second portions (552)) of the third layer (503) may each include members (or materials) having a second refractive index higher than the first refractive index. The first portion (551) of the third layer (503) may be in contact with the second portions of the third layer (503).
[0065] The third layer (503) may include a third portion (553) that covers the first portion (551) of the third layer (503) and includes a member (or material) having the second refractive index. The third portion (553) of the third layer (503) may be in contact with the second portions of the third layer (503).
[0066] Since the first refractive index, which is the refractive index of the first portion (551) of the third layer (503), is lower than the second refractive index, which is the refractive index of the second portions (e.g., the second portions (552)) of the third layer (503), a portion of the light emitted from the second light-emitting portions (e.g., the second light-emitting portions (532)) may be refracted toward the direction of the display panel (160) (or the direction of the display area). For example, the portion of the light emitted by the first portion (551) of the third layer (503) may be refracted due to the difference between the refractive index (e.g., the first refractive index) of the first portion (551) of the third layer (503) and the refractive index (e.g., the second refractive index) of the second portions (e.g., the second portions (552)) of the third layer (503). For example, as indicated by arrow (590), the part of the light may be transmitted (or transferred) toward a space (e.g., the first space) in front of the display panel (160) (or the display area of the display panel (160)) by the difference between the refractive index (e.g., the first refractive index) of the first part (551) of the third layer (503) and the refractive index (e.g., the second refractive index) of the second parts (e.g., the second parts (552)) of the third layer (503). For example, light emitted from the second light-emitting parts in the display panel (160) including the third layer (503) may be concentrated on the space (e.g., the first space) in front of the display panel (160) (or the display area of the display panel (160). The concentration of the light on the space is described with reference to FIG. 6.
[0067] Fig. 6 is a chart showing the distribution of the luminance of the display panel according to the first configuration example by observation position.
[0068] Referring to FIG. 6, the horizontal axis of the chart (600) represents an angle. The angle can be described as the angle between the position for observing the screen displayed on the display panel (160) and the direction of the display panel (160) (or the display area). The vertical axis of the chart (600) represents brightness.
[0069] A line (601) in the chart (600) represents the distribution of the luminance of light emitted from the second light-emitting portions in the display panel (160) omitting the third layer (503) according to the observation position. A line (602) in the chart (600) represents the distribution of the luminance of light emitted from the second light-emitting portions in the display panel (160) including the third layer (503) according to the observation position. Even if the first current provided to emit light from the second light-emitting portions in the display panel (160) omitting the third layer (503) as represented by lines (601) and (602) is greater than the second current provided to emit light from the second light-emitting portions in the display panel (160) including the third layer (503), the luminance of the light from the second light-emitting portions in the display panel (160) including the third layer (503) may be higher than the luminance of the light from the second light-emitting portions in the display panel (160) omitting the third layer (503) within the position range (620) corresponding to the first space. For example, the third layer (503) may compensate for the luminance corresponding to the difference (610) between lines (601) and (602) within the position range (620).
[0070] For example, the third layer (503) may be included within the display panel (160) to maintain brightness while reducing the current provided to each of the second light-emitting portions. Since the current may be reduced by the third layer (503), the lifespan of the second light-emitting portions may be relatively prolonged.
[0071] Referring back to FIG. 5, the display panel (160) may further include a fourth layer (504) disposed between the second layer (502) and the third layer (503). The fourth layer (504) may include first filter portions (e.g., first filter portions (561)) disposed over the first light-emitting portions (e.g., first light-emitting portions (531)) and allowing light having a color corresponding to the color of light emitted from each of the first light-emitting portions (e.g., first light-emitting portions (531)) to pass through, and second filter portions (e.g., second filter portions (562)) disposed over the second light-emitting portions (e.g., second light-emitting portions (532)) and allowing light having a color corresponding to the color of light emitted from each of the second light-emitting portions (e.g., second light-emitting portions (532)) to pass through.
[0072] For example, the first filter portions (561) may include a first filter portion (561-1) and a first filter portion (561-2). The first filter portion (561-1) may allow light having the first color to pass through. The first filter portion (561-2) may allow light having the second color to pass through. For example, the second filter portions (562) may include a second filter portion (562-1) and a second filter portion (562-2). The second filter portion (562-1) may allow light having the first color to pass through. The second filter portion (562-2) may allow light having the second color to pass through.
[0073] For example, the fourth layer (504) may be included in the display panel (160) to increase the clarity of light emitted from the first light-emitting portions and to increase the clarity of light emitted from the second light-emitting portions.
[0074] As an example that is not limited thereto, the fourth layer (504) may be replaced with a layer that includes first polarizing portions corresponding to the first filter portions and second polarizing portions corresponding to the second filter portions. For example, the first polarizing portions may be included in the layer to compensate for reduced visibility of a screen on the display panel (160) due to external light, having a color corresponding to a color of light emitted from each of the first light-emitting portions. For example, the second polarizing portions may be included in the layer to compensate for reduced visibility of a screen on the display panel (160) due to external light, having a color corresponding to a color of light emitted from each of the second light-emitting portions.
[0075] For example, the fourth layer (504) may not be flat because it includes the first filter portions and the second filter portions. For example, the display panel (160) may include a fifth layer (505) positioned between the third layer (503) and the fourth layer (504) for a flat surface of the display panel (160). The fifth layer (505) may be embedded between the third layer (503) and the fourth layer (504) to flatten the display panel (160).
[0076] The display panel (160) may include a sixth layer (506), which is an encapsulating layer that encapsulates the second layer (502) (or the light-emitting portions (e.g., the first light-emitting portions (531) and the second light-emitting portions (532)) within the second layer (502). The sixth layer (506) may be disposed between the second layer (502) and the third layer (503). The sixth layer (506) may be disposed between the second layer (502) and the fourth layer (504).
[0077] The display panel (160) may be a touch-sensitive display panel. For example, the display panel (160) may include one or more patterned layers (e.g., touch panels) (not shown) to provide electrodes for identifying (or sensing) (or recognizing) a touch input. For example, the one or more layers may be disposed between the second layer (502) and the third layer (503). For example, the one or more layers may be disposed between the second layer (502) and the fourth layer (504). For example, the one or more layers may be disposed between the fourth layer (504) and the sixth layer (506). For example, the one or more layers may be disposed between the first layer (501) and the third layer (503).
[0078] Figure 7 is a cross-sectional view of a display panel according to a second configuration example.
[0079] Figure 7 is a cross-sectional view of AB in Figure 4.
[0080] Referring to FIG. 7, the third layer (503) of the display panel (160) illustrated in FIG. 5 may be replaced with the third layer (703) of the display panel (160) illustrated in FIG. 7. The third layer (703) may be included in the display panel (160) to expand the range of positions within which information displayed within the normal display mode can be recognized.
[0081] The third layer (703) may be disposed between the first layer (501) and the second layer (502) (or the sixth layer (506)) (or the fourth layer (504)) (or the fifth layer (505)). The third layer (703) may include first portions (e.g., first portions (751)) each including a member (or material) having the first refractive index, and second portions (752) disposed on the first insulating portion (541) of the second layer (502) between the first light-transmitting portions (e.g., first light-transmitting portions (511)) of the opaque member (510) of the first layer (501) and the first light-emitting portions (e.g., first light-emitting portions (531)) of the second layer (502). The first portions of the third layer (703) can be in contact with the second portion (752) of the third layer (703).
[0082] The third layer (703) may include third portions (e.g., third portions (753)) that cover the first portions (e.g., first portions (751)) of the third layer (703) and include a member (or material) having the second refractive index. The third portions of the third layer (703) may be in contact with the second portion (752) of the third layer (703).
[0083] Since the first refractive index, which is the refractive index of the first portions (e.g., the first portions (751)) of the third layer (703) is lower than the second refractive index, which is the refractive index of the second portions (752) of the third layer (703), a portion of the light emitted from the first light-emitting portions (e.g., the first light-emitting portions (531)) may be refracted to face in a different direction that is distinct from the direction of the display panel (160). For example, at least a portion of the light passing through the first portions (e.g., the first portions (751)) of the third layer (703) may be refracted due to the difference between the refractive index (e.g., the first refractive index) of the first portions (e.g., the first portions (751)) of the third layer (703) and the refractive index (e.g., the second refractive index) of the second portions (752) of the third layer (703). For example, as indicated by arrows (790), at least a portion of the light passing through the first portions (e.g., the first portions (751)) of the third layer (703) may be transmitted (or transferred) toward the second space due to the difference between the refractive index (e.g., the first refractive index) of the first portions (e.g., the first portions (751)) of the third layer (703) and the refractive index (e.g., the second refractive index) of the second portion (752) of the third layer (703). For example, the light emitted from the first light-emitting portions within the display panel (160) including the third layer (703) may be relatively widely spread. The relatively widely spread light is described with reference to FIG. 8.
[0084] Fig. 8 is a chart showing the distribution of the luminance of the display panel according to the second configuration example by observation position.
[0085] Referring to Fig. 8, the horizontal axis of the chart (800) represents an angle. The angle can be described as the angle between the position for observing the screen displayed on the display panel (160) and the direction of the display panel (160) (or the display area). The vertical axis of the chart (800) represents brightness.
[0086] A line (801) in the chart (800) represents the distribution of the luminance of light emitted from the first light-emitting portions in the display panel (160) omitting the third layer (703) according to the observation position. A line (802) in the chart (800) represents the distribution of the luminance of light emitted from the first light-emitting portions in the display panel (160) including the third layer (703) according to the observation position. When the second current provided to emit light from the first light-emitting portions in the display panel (160) including the third layer (703) is (slightly) greater than the first current provided to emit light from the first light-emitting portions in the display panel (160) omitting the third layer (703), the position range in which light from the first light-emitting portions in the display panel (160) including the third layer (703) can be viewed may be wider than the position range in which light from the first light-emitting portions in the display panel (160) omitting the third layer (703), as indicated by the difference (810) between lines (802) and (801). For example, the third layer (703) may widen the position range in which information in a screen displayed on the display panel (160) according to the normal display mode can be viewed. As a non-limiting example, the second current is (slightly) larger than the first current, but since the first light-emitting portions are used for the normal display mode among the normal display mode and the privacy display mode, the third layer (703) can enhance the visual quality of the screen displayed on the display panel (160).
[0087] Referring again to FIG. 7, the display panel (160) including the third layer (703) may be a touch-sensitive display panel. For example, the display panel (160) may include one or more layers (e.g., touch panels) (not shown) patterned to provide electrodes for identifying (or sensing) (or recognizing) a touch input. For example, the one or more layers may be disposed between the second layer (502) and the third layer (703). For example, the one or more layers may be disposed between the second layer (502) and the fourth layer (504). For example, the one or more layers may be disposed between the fourth layer (504) and the sixth layer (506). For example, the one or more layers may be disposed between the first layer (501) and the third layer (703).
[0088] The third layer (503) illustrated in FIG. 5 may further include structures corresponding to the first portions (751), second portions (752), and third portions (753) of the third layer (703) illustrated in FIG. 7. The third layer (503) further including the above structures is described with reference to FIG. 9.
[0089] Figure 9 is a cross-sectional view of a display panel according to a third configuration example.
[0090] Figure 9 is a cross-sectional view of AB of Figure 4.
[0091] Referring to FIG. 9, the third layer (503) may further include fourth portions (e.g., fourth portions (954) of the third layer (503)) disposed between the first light-transmitting portions (e.g., first light-transmitting portions (511)) of the opaque member (510) of the first layer (501) and the first light-emitting portions (e.g., first light-emitting portions (531)) of the second layer (502) and having the first refractive index. The third layer (503) may further include a fifth portion (955) disposed on the first insulating portion (541) of the second layer (502) and having the second refractive index. The third layer (503) may further include sixth portions (956) each covering the fourth portions (e.g., the fourth portions (954) of the third layer (503)) of the third layer (503) and having the second refractive index.
[0092] The first part (551) of the third layer (503) can be connected to some of the fourth parts (e.g., the fourth parts (954)) of the third layer (503). Since the refractive indices of the first part (551) of the third layer (503) and the fourth parts (954) of the third layer (503) are the same as the first refractive index, the first part (551) of the third layer (503) can be connected to some of the fourth parts (e.g., the fourth parts (954)) of the third layer (503). The first part (551) of the third layer (503) connected to some of the fourth parts of the third layer (503) is described with reference to FIG. 10.
[0093] Fig. 10 is a cross-sectional view of a display panel according to a fourth configuration example.
[0094] Figure 10 is a cross-sectional view of AB in Figure 4.
[0095] Referring to FIG. 10, the display panel (160) may include the first pixel including sub-pixels, each including light-emitting elements that provide the first light-emitting portions, and the second pixel including light-emitting elements that provide the second light-emitting portions, respectively. For example, the first pixel may include first light-emitting portions (531). For example, the second pixel may include second light-emitting portions (532).
[0096] For example, a first portion (551) of a third layer (503) within a display panel (160) may be connected to a portion of the fourth portions (e.g., the fourth portions (954)) of the third layer (503) above a boundary portion (1002) between the first pixel including the first light-emitting portions (531) and the second pixel including the second light-emitting portions (532). For example, a first portion (551) of the third layer (503) may be connected to a fourth portion (954-1) of the third layer (503), which is one of the fourth portions (954) of the third layer (503), above the boundary portion (1002). For example, the first part (551) of the third layer (503) may be connected to the fourth part (954-1) of the third layer (503) through the seventh part (1001) of the third layer (503) having the first refractive index. Unlike the fourth part (954-2) of the third layer (503), the fourth part (954-1) of the third layer (503) may be connected to the first part (551) of the third layer (503) through the seventh part (1001) of the third layer (503).
[0097] For example, a display panel (160) including a third layer (503) illustrated in FIG. 5 may include structures corresponding to the first portions (751), second portions (752), and third portions (753) of the third layer (703) illustrated in FIG. 7, within a layer disposed over the third layer (503). The layer disposed over the third layer (503) of the display panel (160) is described with reference to FIG. 11.
[0098] Fig. 11 is a cross-sectional view of a display panel according to a fifth configuration example.
[0099] Figure 11 is a cross-sectional view of AB in Figure 4.
[0100] Referring to FIG. 11, a display panel (160) including a third layer (503) may further include a seventh layer (1107) disposed on the first layer (501).
[0101] The seventh layer (1107) may be disposed on the first light-transmitting portions (e.g., the first light-transmitting portions (511)) of the opaque member (510) of the first layer (501) and may include first portions (e.g., the first portions (1154)) having the first refractive index. The seventh layer (1107) may be disposed on the first insulating portion (541) of the second layer (502) and may include second portions (1155) having the second refractive index. The seventh layer (1107) may cover the first portions (e.g., the first portions (1154)) of the seventh layer (1107) and may include third portions (1156) having the second refractive index.
[0102] Since the first refractive index, which is the refractive index of the first portions (e.g., the first portions (1154)) of the seventh layer (1107) is lower than the second refractive index, which is the refractive index of the second portion (1155) of the seventh layer (1107), a portion of the light emitted from the first light-emitting portions (e.g., the first light-emitting portions (531)) may be refracted in a different direction that is distinct from the direction of the display panel (160). For example, at least a portion of the light passing through the first portions (e.g., the first portions (1154)) of the seventh layer (1107) may be refracted due to the difference between the refractive index (e.g., the first refractive index) of the first portions (e.g., the first portions (1154)) of the seventh layer (1107) and the refractive index (e.g., the second refractive index) of the second portion (1155) of the seventh layer (1107). For example, as indicated by arrows (1190), at least a portion of light passing through the first portions (e.g., the first portions (1154)) of the seventh layer (1107) may be transmitted (or transferred) toward the second space due to a difference between a refractive index (e.g., the first refractive index) of the first portions (e.g., the first portions (1154)) of the seventh layer (1107) and a refractive index (e.g., the second refractive index) of the second portion (1155) of the seventh layer (1107). For example, light emitted from the first light-emitting portions within the display panel (160) including the seventh layer (1107) may be relatively widely spread.
[0103] Figures 12 to 25 are cross-sectional views of display panels according to various configuration examples.
[0104] Figures 12 to 25 are cross-sectional views of AB in Figure 4.
[0105] Referring to FIG. 12, each of the display panels (160) illustrated in FIG. 5, the display panels (160) illustrated in FIG. 7, and the display panels (160) illustrated in FIG. 9 may not include the fifth layer (505), as in example configurations (1200), (1230), and (1260). For example, since flattening to compensate for an uneven fourth layer (504) may be provided by the third layer (503) (or the seventh layer (703)), the fifth layer (505) may be omitted (or removed) from each of the display panels (160) illustrated in FIG. 5, the display panels (160) illustrated in FIG. 7, and the display panels (160) illustrated in FIG. 9. For example, the third layer (503) can be disposed on the fourth layer (504), as in configuration examples (1200) and (1260). For example, the third layer (503) can be in contact with the fourth layer (504), as in configuration examples (1200) and (1260).

Referring to FIG. 27, the display module (2660) may include a display (2710) and a display driver IC (DDI) (2730) for controlling the display (2710). The DDI (2730) may include an interface module (2731), a memory (2733) (e.g., a buffer memory), an image processing module (2735), or a mapping module (2737). The DDI (2730) may receive image information including, for example, image data or an image control signal corresponding to a command for controlling the image data, from another component of the electronic device (2601) through the interface module (2731). For example, according to one embodiment, image information may be received from a processor (2620) (e.g., a main processor (2621) (e.g., an application processor) or an auxiliary processor (2623) (e.g., a graphics processing unit) that operates independently of the function of the main processor (2621).

In addition, the DDI (2730) may store at least a part of the received image information in the memory (2733), for example, in units of frames. The image processing module (2735) may, for example, perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least a part of the image data based on at least a characteristic of the image data or a characteristic of the display (2710). The mapping module (2737) may output a voltage value or a value corresponding to the image data preprocessed or postprocessed through the image processing module (2735). Current values can be generated.According to one embodiment, the generation of voltage values or current values may be performed at least in part based on, for example, properties of pixels of the display (2710) (e.g., arrangement of pixels (RGB stripe or pentile structure), or size of each sub-pixel). At least some pixels of the display (2710) may be driven at least in part based on, for example, the voltage values or current values, so that visual information (e.g., text, images, or icons) corresponding to the image data may be displayed through the display (2710).
[0174] According to one embodiment, the display module (2660) may further include a touch circuit (2750). The touch circuit (2750) may include a touch sensor (2751) and a touch sensor IC (2753) for controlling the same. The touch sensor IC (2753) may control the touch sensor (2751) to detect, for example, a touch input or a hovering input for a specific location of the display (2710). For example, the touch sensor IC (2753) may detect the touch input or the hovering input by measuring a change in a signal (e.g., voltage, light quantity, resistance, or charge quantity) for a specific location of the display (2710). The touch sensor IC (2753) may provide information (e.g., location, area, pressure, or time) regarding the detected touch input or hovering input to the processor (2620). According to one embodiment, at least a portion of the touch circuit (2750) (e.g., touch sensor IC (2753)) may be included as part of the display driver IC (2730), or as part of the display (2710), or as part of another component (e.g., coprocessor (2623)) disposed external to the display module (2660).
[0175] According to one embodiment, the display module (2660) 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 (2676), 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 (2660) (e.g., the display (2710) or the DDI (2730)) or a part of the touch circuit (2750). For example, when the sensor module (2676) embedded in the display module (2660) 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 (2710). For another example, if the sensor module (2676) embedded in the display module (2660) includes a pressure sensor, the pressure sensor may obtain pressure information associated with a touch input through a portion or the entire area of the display (2710). According to one embodiment, the touch sensor (2751) or the sensor module (2676) may be disposed between pixels of a pixel layer of the display (2710), or above or below the pixel layer.
