Display panel and display device

[0001] This application claims priority to Chinese Patent Application No. 202411042209.4, filed with the China National Intellectual Property Administration on July 30, 2024, entitled "Display Panel and Display Device", and priority to Chinese Patent Application No. 202411062340.7, filed with the China National Intellectual Property Administration on August 2, 2024, also entitled "Display Panel and Display Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of display technology, and more specifically, to a display panel and a display device. Background Technology

[0003] With the development of display technology, display products such as mobile phones and tablets are being used more and more widely. When using these products, users want to share their display information with others, but also want privacy in certain situations to prevent others from peeping at their information. However, current privacy display technologies often sacrifice screen resolution, affecting the display effect. Summary of the Invention

[0004] This application provides a display panel and display device that can achieve high screen resolution, high pixel aperture ratio, and improve display effect.

[0005] In a first aspect, a display panel is provided, the display panel including a substrate and a light-emitting layer disposed on the substrate, the light-emitting layer including a plurality of pixel partitions, each pixel partition including a first pixel unit; the first pixel unit having at least two colors and two types of sub-pixels along a first direction; the first pixel unit having at least two types of sub-pixels along a second direction, or the first pixel unit having sub-pixels of different colors but the same type along the second direction; wherein the sub-pixels of different types emit light individually in different modes, and the second direction is perpendicular to the first direction.

[0006] In one example, the first pixel unit has at least two colors and at least two types of sub-pixels along a first direction, and the first pixel unit has at least two types of sub-pixels along a second direction.

[0007] In this example, the display panel can employ the following pixel arrangement: in the first direction (e.g., the row direction), it can have at least two colors and at least two types of sub-pixels; in the second direction (e.g., the column direction), it can have at least two types of sub-pixels, and the colors of the sub-pixels in the second direction can be the same or different. This allows for the staggered arrangement of adjacent first-type and second-type sub-pixels in both the first and second directions, resulting in a larger opening area on the metal mask used to fabricate the pixel arrangement structure. This improves the pixel aperture ratio, increases the light-emitting area, and enhances the display panel's brightness, lifespan, and screen resolution. Furthermore, within each pixel unit, the first-type and second-type sub-pixels are evenly distributed, fully utilizing the space. When displaying either the first-type or second-type sub-pixels individually, sub-pixels are displayed in both the row and column directions, eliminating the issue of black lines and resulting in a better display effect.

[0008] In another example, the first pixel unit has at least two colors and at least two types of sub-pixels along a first direction, and the first pixel unit has sub-pixels of different colors but the same type along a second direction.

[0009] In this example, the display panel can employ the following pixel arrangement: in the first direction (e.g., the row direction), it can have at least two colors and at least two types of sub-pixels; in the second direction (e.g., the column direction), it can have sub-pixels of different colors but the same type. This allows for an alternating arrangement of adjacent first-type and second-type sub-pixels in both the first and second directions, resulting in a larger opening area on the metal mask used to fabricate the pixel arrangement structure. This improves the pixel aperture ratio, increases the light-emitting area, and enhances the display panel's brightness, lifespan, and screen resolution. Furthermore, within each pixel unit, the first-type and second-type sub-pixels are evenly distributed, fully utilizing the space. When displaying either the first-type or second-type sub-pixels individually, sub-pixels are displayed in both the row and column directions, eliminating the black line display issue and resulting in a better display effect.

[0010] For example, the at least two types of sub-pixels may include a first type of sub-pixel and a second type of sub-pixel, and different types of sub-pixels may emit light independently in different modes. For example, in a first mode, the emissive layer may illuminate the first type of sub-pixels independently; in a second mode, the emissive layer may illuminate the second type of sub-pixels independently.

[0011] In some examples, the first type of subpixel can be a privacy subpixel, and the second type of subpixel can be a shared subpixel; the first mode can be a privacy mode (or privacy mode), and the second mode can be a shared mode.

[0012] In other examples, the first mode can be the display mode corresponding to the first color gamut, and the second mode can be the display mode corresponding to the second color gamut, where the first and second color gamuts are different. That is, the first and second types of subpixels may not be used to switch between privacy and sharing, but rather to display different color gamuts; in other words, the first and second types of subpixels can correspond to subpixels displayed in different color gamuts. For example, when displaying only the first type of subpixel, it can correspond to the first color gamut; when displaying only the second type of subpixel, it can correspond to the second color gamut.

[0013] In some other examples, the first mode can be an anti-glare mode and the second mode can be a non-anti-glare mode. In the first mode, the light-emitting layer can light up the first type of sub-pixels individually, so that the display panel has an anti-glare function. In the second mode, the light-emitting layer can light up the second type of sub-pixels individually. At this time, the display panel may not have an anti-glare function.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the first pixel unit includes a first type of sub-pixel and a second type of sub-pixel of different types; wherein, along the first direction, the first type of sub-pixel and the second type of sub-pixel are alternately arranged, and / or, along the second direction, the first type of sub-pixel and the second type of sub-pixel are alternately arranged.

[0015] In the display panel provided in this application, a pixel unit may include different types of first-type sub-pixels and second-type sub-pixels. In the first direction and / or the second direction, the first-type sub-pixels and second-type sub-pixels can be alternately set, so that the first-type sub-pixels and second-type sub-pixels are evenly distributed and the space can be fully utilized. When the first-type sub-pixels or the second-type sub-pixels are displayed alone, there are sub-pixels displayed in both the row and column directions, so there is no problem of displaying black lines and the display effect is better.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, each pixel partition further includes a second pixel unit, and the first pixel unit and the second pixel unit in each pixel partition are arranged adjacent to each other; the second pixel unit has at least two colors and at least two types of sub-pixels along the first direction; the second pixel unit has at least two types of sub-pixels along the second direction, or the second pixel unit has sub-pixels of different colors and the same type along the second direction.

[0017] For example, the first pixel unit and the second pixel unit within the pixel partition are arranged adjacent to each other along the first direction, and the arrangement of the sub-pixels in the second pixel unit is mirror-symmetrical to the arrangement of the sub-pixels in the first pixel unit about the first direction. This arrangement can improve the pixel aperture ratio, increase the light-emitting area, and improve the display panel's brightness, lifespan, and screen resolution.

[0018] For example, the arrangement of sub-pixels in the second pixel unit is the same as the arrangement of sub-pixels in the first pixel unit, or the arrangement of sub-pixels in the second pixel unit is the same as the arrangement of sub-pixels in the first pixel unit after overall rotation by a preset angle. This preset angle can be, for example, 90°, 180°, 270°, 360°, etc.

[0019] For example, the light-emitting layer may include a plurality of repeating pixel partitions, each pixel partition may include a first pixel unit and a second pixel unit, and within the first pixel unit and / or the second pixel unit, there may be two different types and three different colors of sub-pixels, for example, there may be: a first type of sub-pixel of a first color, a first type of sub-pixel of a second color and a first type of sub-pixel of a third color; and a second type of sub-pixel of a first color, a second type of sub-pixel of a second color and a second type of sub-pixel of a third color.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the first pixel unit includes an adjacent first sub-pixel and a second sub-pixel, wherein the first sub-pixel and the second sub-pixel have the same color but different types.

[0021] In the display panel provided in this application, within the first pixel unit or the second pixel unit, adjacent first sub-pixels and second sub-pixels of different types can have the same color. Sub-pixels with the same color can share the opening of the metal mask for color evaporation, thereby increasing the pixel aperture ratio.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the minimum distance between adjacent sub-pixels of the same color is greater than or equal to a first threshold, and the minimum distance between adjacent sub-pixels of different colors is greater than or equal to a second threshold. The maximum size of the first type of sub-pixels can be less than or equal to a third threshold, which can be, for example, 50 μm.

[0023] It should be understood that the minimum distance between adjacent sub-pixels of the same color is greater than or equal to the isolation pillar process limit distance, which can range from 1μm to 5μm, i.e., the first threshold can be 1μm to 5μm. The minimum distance between adjacent sub-pixels of different colors is greater than or equal to the pixel-limited layer spacing (PDL GAP) process limit distance, which can range from 10μm to 20μm, i.e., the second threshold can be 10μm to 20μm.

[0024] In the display panel provided in this application, to meet the requirements of manufacturing, the minimum distance between adjacent sub-pixels of the same color satisfies a first threshold. This first threshold can be the limit distance of the isolation pillar process, and this limit distance can be reduced with the improvement of manufacturing processes and methods. To avoid light crosstalk between sub-pixels of different colors, the minimum distance between adjacent sub-pixels can be limited to meet a second threshold. This second threshold can be the limit distance of the PDL GAP process, and this limit distance can be reduced with the improvement of manufacturing processes and methods.

[0025] In conjunction with the first aspect, in some implementations of the first aspect, the first pixel unit includes a third sub-pixel, the second pixel unit includes a fourth sub-pixel, the third sub-pixel and the fourth sub-pixel are adjacent, and the third sub-pixel and the fourth sub-pixel have the same color but different types.

[0026] In the display panel provided in this application, the colors of adjacent sub-pixels of adjacent first pixel units and second pixel units can be the same. Sub-pixels with the same color can share the opening of the metal mask for color evaporation, thereby further increasing the pixel aperture ratio.

[0027] In conjunction with the first aspect, in some implementations of the first aspect, the ratio of the total area of ​​the first type of sub-pixels to the total area of ​​the second type of sub-pixels within the first pixel unit or the second pixel unit ranges from 0.2 to 5.

[0028] For example, each pixel partition may include a first pixel unit and a second pixel unit. The first pixel unit or the second pixel unit may include a first type of sub-pixel unit and a second type of sub-pixel unit. The first type of sub-pixel unit is composed of first type of sub-pixels. For example, the first type of sub-pixel unit may include first type of sub-pixels of a first color, first type of sub-pixels of a second color, and first type of sub-pixels of a third color. The second type of sub-pixel unit is composed of second type of sub-pixels. For example, the second type of sub-pixel unit may include second type of sub-pixels of a first color, second type of sub-pixels of a second color, and second type of sub-pixels of a third color.

[0029] For example, if the display panel commonly uses a shared display mode, the area of ​​the second type of sub-pixels can be set to be greater than or equal to the area of ​​the second type of sub-pixels. For instance, the ratio of the total area of ​​the first type of sub-pixels to the area of ​​the second type of sub-pixels can range from 0.2 to 1. If the display panel commonly uses a privacy mode (or privacy protection mode), the total area of ​​the first type of sub-pixels can be set to be greater than or equal to the total area of ​​the second type of sub-pixels. For instance, the ratio of the total area of ​​the first type of sub-pixels to the area of ​​the second type of sub-pixels can range from 1 to 5.

[0030] In the display panel provided in this application, the areas of the first type of sub-pixels and the second type of sub-pixels can be set according to the common mode of the display panel. If the common mode is privacy mode, the total area of ​​the first type of sub-pixels in a pixel unit can be set to be greater than or equal to the total area of ​​the second type of sub-pixels. If the common mode is sharing mode, the total area of ​​the first type of sub-pixels in a pixel unit can be set to be less than or equal to the total area of ​​the second type of sub-pixels. By increasing the area of ​​the commonly used sub-pixels in the display panel, the aperture ratio can be increased, and the service life of the display panel can be improved.

[0031] In conjunction with the first aspect, in some implementations of the first aspect, the maximum emission angle of the light emitted from the first type of sub-pixel is smaller than the maximum emission angle of the light emitted from the second type of sub-pixel.

[0032] In the display panel provided in this application, the first type of sub-pixel can be a privacy sub-pixel, and the second type of sub-pixel can be a shared sub-pixel. The maximum emission angle of the light emitted from the shared sub-pixel can be greater than the maximum emission angle of the light emitted from the privacy sub-pixel, thereby enabling the viewing range of the shared sub-pixel to be greater than that of the privacy sub-pixel. In other words, the second type of sub-pixel has a large viewing angle, while the first type of sub-pixel has a relatively small viewing angle, in order to achieve the function of privacy protection. For example, when the viewing angle is greater than 45°, the user cannot observe the content on the display panel.

[0033] In conjunction with the first aspect, in some implementations of the first aspect, the first pixel unit or the second pixel unit includes different types of first-class sub-pixels and second-class sub-pixels in the second direction. The first pixel unit or the second pixel unit includes first-class sub-pixels of a first color, first-class sub-pixels of a second color, first-class sub-pixels of a third color, second-class sub-pixels of a first color, second-class sub-pixels of a second color, and second-class sub-pixels of a third color. Along the first direction, the first-class sub-pixels of the first color, the second-class sub-pixels of the first color, and the first-class sub-pixels of the second color are arranged in a row, and the second-class sub-pixels of the second color, the first-class sub-pixels of the third color, and the second-class sub-pixels of the third color are arranged in a row. Along the second direction, the first-class sub-pixels of the first color and the second-class sub-pixels of the second color are arranged in a column, the second-class sub-pixels of the first color and the first-class sub-pixels of the third color are arranged in a column, and the first-class sub-pixels of the second color and the second-class sub-pixels of the third color are arranged in a column.

[0034] It should be understood that within the first pixel unit or the second pixel unit, first-type sub-pixels of different colors can form an inverted equilateral triangle arrangement, and second-type sub-pixels of different colors can form an upright equilateral triangle arrangement; or, first-type sub-pixels of different colors can also form an upright equilateral triangle arrangement, and second-type sub-pixels of different colors can form an inverted equilateral triangle arrangement.

[0035] In the display panel provided in this application, within the first pixel unit or the second pixel unit, first-type sub-pixels of different colors can be arranged in an equilateral triangle, and second-type sub-pixels of different colors can also be arranged in an equilateral triangle. This allows for full utilization of space within each pixel unit, and when the first-type or second-type sub-pixels are displayed individually, sub-pixels are displayed in both the row and column directions, thus eliminating the problem of black lines and providing a better display effect. Furthermore, within the first pixel unit or the second pixel unit, adjacent first-type and second-type sub-pixels can be of the same color. Sub-pixels of the same color can share the opening of the metal mask for color deposition, thereby increasing the pixel aperture ratio.

[0036] In conjunction with the first aspect, in some implementations of the first aspect, the first pixel unit has sub-pixels of different colors but the same type along the second direction. The first pixel unit or the second pixel unit includes a first type of sub-pixel of a first color, a first type of sub-pixel of a second color, a first type of sub-pixel of a third color, a second type of sub-pixel of a first color, a second type of sub-pixel of a second color, and a second type of sub-pixel of a third color. Along the first direction, the first type of sub-pixel of the first color, the first type of sub-pixel of the second color, and the second type of sub-pixel of the first color are arranged in a row, and the first type of sub-pixel of the third color, the second type of sub-pixel of the second color, and the second type of sub-pixel of the third color are arranged in a row. Along the second direction, the first type of sub-pixel of the first color and the first type of sub-pixel of the third color are arranged in a column, the first type of sub-pixel of the second color and the second type of sub-pixel of the second color are arranged in a column, and the second type of sub-pixel of the first color and the second type of sub-pixel of the third color are arranged in a column.

[0037] It should be understood that within the first pixel unit or the second pixel unit, first-type sub-pixels of different colors can form an inverted right-angled triangle arrangement, and second-type sub-pixels of different colors can form an upright right-angled triangle arrangement; or, first-type sub-pixels of different colors can also form an upright right-angled triangle arrangement, and second-type sub-pixels of different colors can form an inverted right-angled triangle arrangement.

[0038] In the display panel provided in this application, within the first pixel unit or the second pixel unit, first-type sub-pixels of different colors can be arranged in right-angled triangles, and second-type sub-pixels of different colors can also be arranged in right-angled triangles. This allows for full utilization of space within each pixel unit, and when displaying the first-type or second-type sub-pixels individually, sub-pixels are displayed in both row and column directions, thus eliminating the problem of black lines and providing a better display effect. Furthermore, within the first pixel unit or the second pixel unit, adjacent first-type and second-type sub-pixels can be of the same color. Sub-pixels of the same color can share the opening of the metal mask for color vapor deposition, thereby increasing the pixel aperture ratio.

[0039] In conjunction with the first aspect, in some implementations of the first aspect, the first type of sub-pixels can be circular. The second type of sub-pixels can be rectangular.

[0040] For example, the first type of sub-pixel can also be ellipse, rectangle, hexagon, octagon, etc., and the second type of sub-pixel can be circle, ellipse, hexagon, octagon, etc.

[0041] In the display panel provided in this application, by setting the first type of sub-pixels to be circular, a 360° all-around privacy display can be achieved, and the aperture ratio can be further increased.

[0042] In conjunction with the first aspect, in some implementations of the first aspect, within the first pixel unit or the second pixel unit, there are two first-type sub-pixels of each color, and the two first-type sub-pixels of the same color are arranged side by side along the second direction.

[0043] For example, within a first pixel unit or a second pixel unit, the number of first-type sub-pixels of the first color can be two, the number of first-type sub-pixels of the second color can be two, and the number of first-type sub-pixels of the third color can be two. Furthermore, the two first-type sub-pixels of the first color can be arranged in a column along a second direction, the two first-type sub-pixels of the second color can be arranged in a column along a second direction, and the two first-type sub-pixels of the third color can be arranged in a column along a second direction.

[0044] For example, the area occupied by two first-class sub-pixels of the same color can be approximately equal to the area occupied by one second-class sub-pixel. Two first-class sub-pixels of the same color are arranged in a row along a second direction, which can be the length direction of a rectangular second-class sub-pixel.

[0045] In the display panel provided in this application, by setting two first-class sub-pixels of each color in each pixel unit and arranging two first-class sub-pixels of the same color in a row along the second direction, the space within the pixel unit can be fully utilized and the aperture ratio can be increased.

[0046] In conjunction with the first aspect, in some implementations of the first aspect, the display panel further includes a light confinement layer disposed on the side of the light-emitting layer away from the substrate; the light confinement layer includes at least one light-shielding layer, wherein the maximum diameter of the opening of the at least one light-shielding layer corresponding to the first type of sub-pixel is smaller than the maximum diameter of the opening of the at least one light-shielding layer corresponding to the second type of sub-pixel.

[0047] It should be understood that two types of openings can be made on the light-shielding layer. One type of opening corresponds to the first type of sub-pixel, and the other type corresponds to the second type of sub-pixel. This allows light emitted from the first and second types of sub-pixels to pass through the openings on the light-shielding layer. Furthermore, the maximum diameter of the opening on the light-shielding layer corresponding to the first type of sub-pixel is smaller than the maximum diameter of the opening on the light-shielding layer corresponding to the second type of sub-pixel. This results in the light angle emitted from the second type of sub-pixel being greater than the light angle emitted from the first type of sub-pixel. In other words, the light-shielding layer can limit the angle of light emitted from the first type of sub-pixel to a certain extent, thereby achieving the function of preventing peeping.

[0048] In some possible implementations, the display panel further includes a light confinement layer disposed on the side of the light-emitting layer away from the substrate; the light confinement layer includes a first light-shielding layer having a first opening, the orthographic projection of the first type of sub-pixel on the substrate being located within the range of the orthographic projection of the first opening on the substrate, and the orthographic projection of the first light-shielding layer on the substrate not overlapping the orthographic projection of the second type of sub-pixel on the substrate.

[0049] In some examples, the first light-shielding layer may be disposed only on the outer periphery of the first type of sub-pixels. That is, the orthographic projection of the first light-shielding layer on the substrate is located outside the orthographic projection of the first type of sub-pixels on the substrate, and the first light-shielding layer may not be disposed at the corresponding position of the second type of sub-pixels. The first light-shielding layer may have multiple first openings, and the shape of the first openings is the same as the shape of the first type of sub-pixels.

[0050] For example, the minimum distance between the edge of the circle formed by the orthographic projection of the first type of sub-pixel on the substrate and the orthographic projection of the first light-shielding layer on the substrate is the process limit distance (e.g., 0.1 μm).

[0051] In the display panel provided in this application, the display panel may further include a light limiting layer, which can be used to limit the emission angle of light. The light limiting layer may include a first light-shielding layer (i.e., a black matrix). By limiting the emission angle of the first type of sub-pixels through the first light-shielding layer, the viewing range that the user can observe can be limited. For example, by limiting the size of the first opening of the first light-shielding layer, when the viewing angle is greater than 45°, the user cannot observe the content on the display panel, thereby achieving a privacy protection function.

[0052] In some examples, the first light-shielding layer may have multiple first openings and multiple third openings. The first openings correspond to a first type of sub-pixel, and the third openings correspond to a second type of sub-pixel. The shape of the first opening is the same as the shape of the first type of sub-pixel, and the shape of the third opening is the same as the shape of the second type of sub-pixel. For example, the first type of sub-pixel is circular, the second type of sub-pixel is rectangular, the projection of the first opening is a circular hole, and the projection of the third opening is a rectangular hole. The minimum distance between the first type of sub-pixel and the edge of the circular hole is a process limit distance (e.g., 0.1 μm), and the minimum distance between the second type of sub-pixel and the edge of the rectangular hole is greater than this process limit distance (e.g., 4 μm).

[0053] In some possible implementations, the light-limiting layer further includes a second light-shielding layer and a dielectric layer located between the first light-shielding layer and the second light-shielding layer, wherein the second light-shielding layer is located on the side of the first light-shielding layer away from the substrate; the second light-shielding layer has a second opening, wherein the orthographic projection of the first type of sub-pixel on the substrate is within the range of the orthographic projection of the second opening on the substrate, and the orthographic projection of the second light-shielding layer on the substrate does not overlap with the orthographic projection of the second type of sub-pixel on the substrate.

[0054] In some examples, the second light-shielding layer may be disposed only on the outer periphery of the first type of sub-pixels. That is, the orthographic projection of the second light-shielding layer on the substrate is located outside the orthographic projection of the first type of sub-pixels on the substrate, and the corresponding position of the second type of sub-pixels may not be provided with the second light-shielding layer. The second light-shielding layer may have multiple second openings, and the shape of the second openings is the same as the shape of the first type of sub-pixels.

[0055] For example, the minimum distance between the edge of the circle formed by the orthographic projection of the first type of sub-pixel on the substrate and the orthographic projection of the second light-shielding layer on the substrate is the process limit distance (e.g., 0.1 μm).

[0056] In the display panel provided in this application, the display panel may further include a light-limiting layer, which can be used to limit the emission angle of light. This light-limiting layer may include a first light-shielding layer (i.e., a black matrix) and a second light-shielding layer. By limiting the emission angle of the first type of sub-pixels through the first and second light-shielding layers, the user's observable field of vision can be limited. For example, by limiting the size of the second opening in the second light-shielding layer, when the viewing angle is greater than 45°, the user cannot observe the content on the display panel, thus achieving a privacy protection function. Furthermore, by setting a double-layer light-shielding layer, light leakage from the first type of sub-pixels can also be avoided, thereby achieving all-around privacy protection.

[0057] In some examples, the second light-shielding layer may have multiple second openings and multiple fourth openings. The second openings correspond to the first type of sub-pixels, and the fourth openings correspond to the second type of sub-pixels. The shapes of the second openings and fourth openings are the same as the shapes of the first and second type of sub-pixels. For example, the first type of sub-pixels are circular, the second type of sub-pixels are rectangular, the projection of the second opening is a circular hole, and the projection of the fourth opening is a rectangular hole. The minimum distance between the first type of sub-pixel and the edge of the circular hole is a process limit distance (e.g., 0.1 μm), and the minimum distance between the second type of sub-pixel and the edge of the rectangular hole is greater than this process limit distance (e.g., 4 μm).

[0058] In conjunction with the first aspect, in some implementations of the first aspect, the light-limiting layer includes a first light-shielding layer, a second light-shielding layer, and a dielectric layer disposed between the first light-shielding layer and the second light-shielding layer, wherein the second light-shielding layer is located on the side of the first light-shielding layer away from the substrate; the first light-shielding layer has a first opening, the second light-shielding layer has a second opening, and the orthographic projection of the second opening on the substrate is within the range of the orthographic projection of the first opening on the substrate.

[0059] In other words, the size of the first opening of the first light-shielding layer can be greater than or equal to the size of the second opening of the second light-shielding layer; that is to say, the size of the second opening of the second light-shielding layer can be less than or equal to the size of the first opening of the first light-shielding layer.

[0060] In the display panel provided in this application, by limiting the size of the second opening to be less than or equal to the size of the first opening, the second light-shielding layer can limit the emission angle of the privacy sub-pixels, thereby limiting the range of vision that the user can observe.

[0061] In conjunction with the first aspect, in some implementations of the first aspect, the display panel further includes an adhesive layer and a functional layer, the adhesive layer being located between the light-emitting layer and the functional layer, and the functional layer being located between the adhesive layer and the first light-shielding layer; at least one film layer in the functional layer has a refractive index greater than the refractive index of the adhesive layer.

[0062] For example, the display panel provided in this application may include a substrate, a light-emitting layer, an adhesive layer, a functional layer, a first light-shielding layer, a dielectric layer and a second light-shielding layer stacked together, wherein the second light-shielding layer may be the outermost layer that is relatively far away from the substrate.

[0063] In the display panel provided in this application, by ensuring that at least one film layer in the functional layer has a refractive index greater than that of the adhesive layer, the width of the first light-shielding layer corresponding to the privacy sub-pixel can be reduced to a certain extent, thereby increasing the pixel's occupied space and thus improving the pixel aperture ratio. Simultaneously, the angle of the emitted light from the shared sub-pixel can be increased, further expanding the visible range of the shared area.

[0064] In conjunction with the first aspect, in some implementations of the first aspect, at least one film layer in the dielectric layer has a refractive index that is less than the refractive index of the adhesive layer.

[0065] In the display panel provided in this application, since at least one film layer in the dielectric layer has a refractive index greater than that of the adhesive layer, the width of the second light-shielding layer corresponding to the first type of sub-pixel can be reduced to a certain extent, thereby increasing the pixel occupied space and further increasing the pixel aperture ratio.

[0066] In conjunction with the first aspect, in some implementations of the first aspect, sub-pixels of the same color and type share a common anode, and first-type sub-pixels and second-type sub-pixels of the same color share a common driving circuit.

[0067] In the display panel provided in this application, by setting sub-pixels of the same color and type to have a shared anode, and first-type sub-pixels and second-type sub-pixels of the same color to have a shared driving circuit, the circuit can be simplified and the circuit layout can be made simpler.

[0068] In conjunction with the first aspect, in some implementations of the first aspect, the display panel has a first mode, a second mode, and a third mode; in the first mode, a first type of sub-pixels on the display panel are turned on and emit light, while a second type of sub-pixels on the display panel are not turned on; in the second mode, a second type of sub-pixels on the display panel are turned on and emit light, while a first type of sub-pixels on the display panel are not turned on; in the third mode, both the first type of sub-pixels and the second type of sub-pixels on the display panel are turned on and emit light.

[0069] For example, the first mode can be a privacy mode (or a privacy protection mode), and the second and third modes can be shared modes. By using a circuit switch, the first, second, and third modes can be actively switched.

[0070] In the display panel provided in this application, users can set the corresponding display mode according to their own needs. For example, if a user wants to enable the privacy function, the display panel can run the first mode; if a user wants to enable the sharing function, the display panel can run the second or third mode.

[0071] In a second aspect, a display device is provided, which includes a display panel as described in any implementation of the first aspect.

[0072] For example, the display device may be a device with a display panel, such as a mobile phone, tablet, personal computer, monitor, television, or vehicle display. Attached Figure Description

[0081] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0082] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more, and "at least one" and "one or more" refer to one, two, or more. The singular expressions "a," "an," "described," "the," "this," and "this" are intended to also include expressions such as "one or more," unless the context explicitly indicates otherwise. The sequence numbers of the processes below do not imply a sequential order of execution; the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application. For example, in the embodiments of this application, the words "100," "200," and "300" are merely identifiers for descriptive convenience and do not limit the order of execution steps.

[0083] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

It should be understood that these directional terms are relative concepts, used for relative description and clarification, and not to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They can change accordingly depending on the orientation of the components in the drawings, and therefore should not be construed as limiting this application.

[0085] Organic light-emitting diode (OLED) displays offer wide viewing angles, enhancing the user experience on smartphones, computers, and tablets. However, when viewing private information, people don't want their screens to be spied on, potentially leading to the leakage of personal privacy or trade secrets. Therefore, an active-matrix organic light-emitting diode (AMOLED) display scheme with switchable privacy and sharing modes has been proposed. Privacy mode refers to a display mode that enables privacy protection, preventing information leakage. The content displayed at wide viewing angles differs from that at normal viewing angles; typically, it displays the normal content at normal viewing angles, while at wide viewing angles it displays completely black, thus preventing information leakage. Sharing mode, distinct from privacy mode, displays the same content at wide viewing angles as at normal viewing angles. While AMOLED displays allow switching between privacy and sharing modes, this leads to a further reduction in pixel aperture ratio or display resolution. In the field of OLED privacy displays, screen resolution and high aperture ratio are crucial for display performance and lifespan.

[0086] OLED display solutions that allow switching between privacy and sharing modes primarily utilize pixel separation. This means the display panel includes privacy sub-pixel units and shared sub-pixel units. The privacy sub-pixel units use technology to achieve a narrow viewing angle, while the shared sub-pixel units maintain the original wide viewing angle. When privacy mode is enabled, only the privacy sub-pixel units are illuminated. When sharing mode is enabled, only the shared sub-pixel units can be illuminated, or both privacy and shared sub-pixel units can be illuminated simultaneously.

[0087] Pixel separation schemes include two categories: pixel segmentation and pixel partitioning. Pixel segmentation involves dividing the original pixel unit into two halves, using one half as a privacy subpixel and the other half as a shared subpixel. Pixel partitioning, on the other hand, does not split the original pixel unit but instead partitions the display panel, setting up privacy subpixel units and shared subpixel units side by side at intervals.

[0088] However, current technical solutions, whether using pixel segmentation or pixel partitioning, cannot effectively achieve high screen resolution and high pixel aperture ratio, which may affect the screen's display quality and lifespan.

[0089] Based on this, the display panel and display device provided in this application embodiment can achieve high resolution and high pixel aperture ratio, thereby improving the display effect and lifespan of the screen.

[0090] Figure 1 is a schematic diagram of the structure of a display panel provided in an embodiment of this application.

[0091] As shown in Figure 1, the display panel 10 may include a driving circuit layer (not shown), a light-emitting pixel layer 200, a thin-film encapsulation layer 300, and a light confinement layer 500 stacked on a substrate 100. For example, if the display panel 10 is an integrated touch display panel, a touch layer 400 may be disposed on the side of the thin-film encapsulation layer 300 away from the substrate 100. The substrate 100 may be a glass substrate or a flexible material; the flexible material may include polyimide (PI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), etc. The driving circuit layer may include thin-film transistors, which can drive the light-emitting pixel layer 200 to switch between different display modes, such as privacy mode and sharing mode. The light-emitting pixel layer 200 includes a light-emitting layer 210 and a pixel defining layer 220 defining the light-emitting layer 210. Furthermore, the light-emitting pixel layer 200 may also include an anode and a cathode (both shown in the figure).

[0092] Referring to Figure 1, the light-emitting layer 210 includes a privacy pixel area (or privacy region) and a normal pixel area (or normal area, shared area). The anodes of the privacy pixel area and the normal pixel area are independent of each other and driven by different thin-film transistors. For example, the light-emitting layer 210 includes a first-color light-emitting layer 211, a second-color light-emitting layer 212, and a third-color light-emitting layer 213, wherein the first color can be red, the second color can be green, and the third color can be blue. The light-emitting pixels of the first-color light-emitting layer 211 and the second-color light-emitting layer 212 can be privacy sub-pixels (or first-type sub-pixels), and the light-emitting pixels of the third-color light-emitting layer 213 can be shared sub-pixels (or second-type sub-pixels).

[0093] The light confinement layer 500 can be used to define the light emission direction of the light-emitting layer 210, allowing it to emit light at a small angle. The light confinement layer 500 may include multiple light-shielding layers. For example, as shown in FIG1, the light confinement layer 500 may include: two light-shielding layers (i.e., a first light-shielding layer 510 and a second light-shielding layer 530), a dielectric layer 520 between the first light-shielding layer 510 and the second light-shielding layer 530, and a surface encapsulation layer 540 covering the second light-shielding layer 530. Exemplarily, each light-shielding layer includes multiple openings, and the opening of the outermost light-shielding layer in the direction away from the substrate 100 is not larger than the openings of the other light-shielding layers. That is, the opening of the second light-shielding layer 530 is smaller than or equal to the opening of the first light-shielding layer 510.

[0094] It should be understood that, in order to balance the light convergence requirements of the privacy pixel area and the light divergence requirements of the normal pixel area, the orthographic projection of the privacy sub-pixel (i.e., the first type of sub-pixel) on the substrate 100 can be located within the opening of the orthographic projection of the first light-shielding layer 510 on the substrate 100, and the orthographic projection of the privacy sub-pixel (i.e., the first type of sub-pixel) on the substrate 100 is located within the opening of the orthographic projection of the second light-shielding layer 530 on the substrate 100. The orthographic projections of the first light-shielding layer 510 and / or the second light-shielding layer 530 on the substrate 100 do not overlap with the orthographic projections of the shared sub-pixel (i.e., the second type of sub-pixel) on the substrate 100.

[0095] The light-shielding layer can be a black matrix that can absorb light and is opaque. By setting a multi-layer composite layer consisting of a first light-shielding layer 510, a dielectric layer 520, a second light-shielding layer 530, and a surface encapsulation layer 540, a light-limiting channel can be formed in the opening area of ​​the multi-layer light-shielding layer. Compared with a single light-shielding layer, the light converging effect is better and the light path limiting effect is superior.

[0096] It should be noted that this application only schematically illustrates a two-layer light-shielding configuration, but is not limited thereto. In other examples, only one light-shielding layer may be provided, or more than two light-shielding layers may be provided, and this application does not limit this. However, the provided light-shielding layer meets the following requirement: the orthographic projections of the privacy sub-pixels (i.e., the first type of sub-pixels) and the shared sub-pixels (i.e., the second type of sub-pixels) on the substrate 100 are both located within the openings of the orthographic projections of the provided light-shielding layer on the substrate 100. That is, the orthographic projections of the privacy sub-pixels (i.e., the first type of sub-pixels) and the shared sub-pixels (i.e., the second type of sub-pixels) on the substrate 100 do not overlap with the orthographic projections of the provided light-shielding layer on the substrate 100.

[0097] Figure 2 is a schematic diagram of pixel partitioning of a display panel according to an embodiment of this application. It should be noted that the pixel partitions and pixel units provided in this embodiment are regional descriptions divided to facilitate the description of the pixel layout of the display panel. Pixel partitions and pixel units may not have actual boundary positions. In practical applications, the position and division boundaries of pixel partitions and pixel units are not limited.

[0098] As shown in Figure 2, the light-emitting layer 210 includes multiple pixel partitions Q1. Each pixel partition Q1 includes adjacent first pixel units Q11 and second pixel units Q12, wherein the first pixel units Q11 and second pixel units Q12 can form a periodic pixel pattern. The first pixel units Q11 and second pixel units Q12 can be the same or different. That is, the arrangement of sub-pixels in the second pixel unit Q12 is the same as the arrangement of sub-pixels in the first pixel unit Q11, or the arrangement of sub-pixels in the second pixel unit Q12 is the same as the arrangement of sub-pixels in the first pixel unit Q11 after rotating the whole by a preset angle. The preset angle can be, for example, 90°, 180°, 270°, 360°, etc. For example, the first pixel units Q11 and second pixel units Q12 in the pixel partition Q1 are arranged adjacent to each other along a first direction, and the arrangement of sub-pixels in the second pixel unit Q12 is mirror-symmetrical to the arrangement of sub-pixels in the first pixel unit Q11 about the first direction.

[0099] In Figure 2, the first pixel unit Q11 is different from the second pixel unit Q12. The second pixel unit Q12 can be obtained by rotating the first pixel unit Q11 by a preset angle in a certain direction. That is to say, the arrangement of the sub-pixels in the second pixel unit Q12 is the same as the arrangement of the sub-pixels after rotating the first pixel unit Q11 by a preset angle.

[0100] Within each pixel unit, in a first direction (e.g., row direction), there are at least two colors of sub-pixels and at least two types of sub-pixels; in a second direction (e.g., column direction), there are at least two types of sub-pixels. The two types of sub-pixels can be understood as including both first-type and second-type sub-pixels, that is, including both privacy sub-pixels and shared sub-pixels. For example, within each pixel unit, in the first direction (e.g., row direction), the red, green, and blue sub-pixels have at least two different colors, and both first-type and second-type sub-pixels exist simultaneously; in the second direction (e.g., column direction), both first-type and second-type sub-pixels exist simultaneously, but the colors of the sub-pixels can be the same or different.

[0101] For example, at least two types of subpixels may include a first type of subpixel and a second type of subpixel, and different types of subpixels may emit light independently in different modes. For example, in the first mode, the emissive layer may illuminate the first type of subpixel independently; in the second mode, the emissive layer may illuminate the second type of subpixel independently.

[0102] In some examples, the first type of subpixel can be a privacy subpixel, and the second type of subpixel can be a shared subpixel; the first mode can be a privacy mode (or privacy mode), and the second mode can be a shared mode.

[0103] In other examples, the first mode can be the display mode corresponding to the first color gamut, and the second mode can be the display mode corresponding to the second color gamut, where the first and second color gamuts are different. That is, the first and second types of subpixels may not be used to switch between privacy and sharing, but rather to display different color gamuts; in other words, the first and second types of subpixels can correspond to subpixels displayed in different color gamuts. For example, when displaying only the first type of subpixel, it can correspond to the first color gamut; when displaying only the second type of subpixel, it can correspond to the second color gamut.

[0104] In some other examples, the first mode can be an anti-glare mode and the second mode can be a non-anti-glare mode. In the first mode, the light-emitting layer can light up the first type of sub-pixels individually, so that the display panel has an anti-glare function. In the second mode, the light-emitting layer can light up the second type of sub-pixels individually. At this time, the display panel may not have an anti-glare function.

[0105] The display panel provided in this application can adopt the following pixel arrangement: in the first direction (e.g., row direction), it can have at least two colors and two types of sub-pixels; in the second direction (e.g., column direction), it can have at least two types of sub-pixels, and the colors of the sub-pixels in the second direction can be the same or different. This allows for the staggered arrangement of adjacent first-type and second-type sub-pixels in the first and second directions, resulting in a larger opening area on the metal mask used to fabricate the pixel arrangement structure. This improves the pixel aperture ratio, increases the light-emitting area, and enhances the display panel's brightness, lifespan, and screen resolution. Furthermore, within each pixel unit, the first-type and second-type sub-pixels are evenly distributed, fully utilizing the space. When displaying either the first-type or second-type sub-pixels individually, sub-pixels are displayed in both the row and column directions, thus eliminating the problem of black lines and achieving a better display effect.

[0106] For example, as shown in Figure 2, the first pixel unit Q11 or the second pixel unit Q12 can be a pixel unit with two rows and three columns (2×3). The first pixel unit Q11 includes a first type of sub-pixel unit P and a second type of sub-pixel unit S. The first pixel unit Q11 includes multiple first type sub-pixels of different colors and multiple second type sub-pixels of different colors. Similarly, the second pixel unit Q12 also includes multiple first type sub-pixels of different colors and multiple second type sub-pixels of different colors. The first type of sub-pixel unit P is composed of multiple first type sub-pixels of different colors, and the second type of sub-pixel unit Q is composed of multiple second type sub-pixels of different colors.

[0107] The first type of sub-pixel unit P may include three first type sub-pixels of different colors, namely, a first type sub-pixel P1 of a first color, a first type sub-pixel P2 of a second color, and a first type sub-pixel P3 of a third color, wherein the first type sub-pixel P1 can be red, the first type sub-pixel P2 can be green, and the first type sub-pixel P3 can be blue; the second type of sub-pixel unit S may include three second type sub-pixels of different colors, namely, a second type sub-pixel S1 of a first color, a second type sub-pixel S2 of a second color, and a third type sub-pixel S3 of a third color, wherein the second type sub-pixel S1 can be red, the second type sub-pixel S2 can be green, and the third type sub-pixel S3 can be blue.

[0108] Within the first pixel unit Q11, in a first direction (e.g., row direction), the first row may include one or more first-type sub-pixels P1 of a first color, one or more second-type sub-pixels S1 of a first color, and one or more first-type sub-pixels P2 of a second color; the second row may include one or more second-type sub-pixels S2 of a second color, one or more first-type sub-pixels P3 of a third color, and one or more second-type sub-pixels S3 of a third color. That is, the row direction of the first pixel unit Q11 includes both first-type and second-type sub-pixels, and the row direction of the first pixel unit Q11 includes either first-type or second-type sub-pixels of at least two colors; the column direction of the first pixel unit Q11 includes both first-type and second-type sub-pixels, and the column direction of the first pixel unit Q11 may include at least two types of first-type sub-pixels. It should be understood that in some other embodiments, the column direction of the first pixel unit Q11 may include either first-type sub-pixels or second-type sub-pixels of the same color.

[0109] Similarly, within the second pixel unit Q12, in the first direction (e.g., the row direction), the first row includes one or more second-type sub-pixels S2 of a second color, one or more first-type sub-pixels P3 of a third color, and one or more second-type sub-pixels S3 of a third color; the second row includes one or more first-type sub-pixels P1 of a first color, one or more second-type sub-pixels S1 of a first color, and one or more first-type sub-pixels P2 of a second color. That is, the row direction of the second pixel unit Q12 includes both first-type and second-type sub-pixels, and the row direction of the second pixel unit Q12 includes either first-type sub-pixels of at least two colors or at least two types of second-type sub-pixels; the column direction of the second pixel unit Q12 includes both first-type and second-type sub-pixels, and the column direction of the second pixel unit Q12 may include at least two types of first-type sub-pixels. It should be understood that in some other embodiments, the column direction of the second pixel unit Q12 may include either first-type sub-pixels of the same color or second-type sub-pixels of the same color.

[0110] The first pixel unit Q11 or the second pixel unit Q12 may include different types of first-type sub-pixels and second-type sub-pixels; wherein, along the first direction, the first-type sub-pixels and second-type sub-pixels are alternately arranged, and / or, along the second direction, the first-type sub-pixels and second-type sub-pixels are alternately arranged. That is, a pixel unit may include different types of first-type sub-pixels and second-type sub-pixels, and in both the first and / or second directions, the first-type sub-pixels and second-type sub-pixels can be alternately arranged, resulting in a uniform distribution of the first-type and second-type sub-pixels, full utilization of space, and, when displaying either the first-type or second-type sub-pixels individually, sub-pixels are displayed in both row and column directions, eliminating the problem of black lines and providing a better display effect.

[0111] The first pixel unit Q11 or the second pixel unit Q12 may include adjacent first sub-pixels and second sub-pixels, which have the same color but different types. Adjacent first sub-pixels and second sub-pixels of different types can have the same color. Sub-pixels with the same color can share the opening of the metal mask for color evaporation, thereby increasing the pixel aperture ratio.

[0112] The first pixel unit Q11 may include a third sub-pixel, and the second pixel unit Q12 may include a fourth sub-pixel. The third and fourth sub-pixels are adjacent, and the third and fourth sub-pixels have the same color but different types. The adjacent sub-pixels of adjacent first pixel units Q11 and second pixel units Q12 can have the same color. Sub-pixels with the same color can share the opening of the metal mask for color evaporation, thereby further increasing the pixel aperture ratio.

[0113] For example, as shown in Figure 2, within the first pixel unit Q11, the lines connecting the centers of the first type of sub-pixels P1, P2, and P3 can form a shape similar to an inverted equilateral triangle, and the lines connecting the centers of the second type of sub-pixels S1, S2, and S3 can form a shape similar to an upright equilateral triangle; within the second pixel unit Q12, the lines connecting the centers of the first type of sub-pixels P1, P2, and P3 can form a shape similar to an upright equilateral triangle, and the lines connecting the centers of the second type of sub-pixels S1, S2, and S3 can form a shape similar to an inverted equilateral triangle. That is, within a pixel unit, the first type of sub-pixels and the second type of sub-pixels are arranged in opposite triangular patterns, i.e., the triangle formed by the lines connecting the centers of the first type of sub-pixels is parallel to the base of the triangle formed by the lines connecting the centers of the second type of sub-pixels, and their vertices are opposite each other.

[0114] In this application embodiment, the shape and number of the first type of sub-pixels and the second type of sub-pixels are not limited. The first type of sub-pixels can be circular, elliptical, rectangular, hexagonal, octagonal, etc., and the number of first type of sub-pixels of the same color can be one or more. The second type of sub-pixels can also be circular, elliptical, rectangular, hexagonal, octagonal, etc., and the number of second type of sub-pixels of the same color can be one or more. Among them, setting the first type of sub-pixels (i.e., privacy sub-pixels) to be circular can achieve 360° all-round privacy display, and can further increase the aperture ratio.

[0115] It should be noted that, in this embodiment, when the first mode is enabled, the display panel can only illuminate the first type of sub-pixel unit P; when the second mode is enabled, the display panel can only illuminate the second type of sub-pixel unit S; and when the third mode is enabled, the display panel can simultaneously illuminate the first type of sub-pixel unit P and the second type of sub-pixel unit S. The first mode can be a privacy mode, where the first type of sub-pixel unit P and the first type of sub-pixel can be privacy sub-pixels; the second and third modes can be shared modes, where the second type of sub-pixel unit Q and the second type of sub-pixel can be shared sub-pixel units. Within each pixel unit, the first and second types of sub-pixels are evenly distributed, and no black lines appear when each mode is enabled, resulting in a good display effect.

[0116] Figure 3 is a schematic diagram of a pixel arrangement method shown in an embodiment of this application.

[0117] As shown in Figure 3, the display panel may include multiple pixel partitions Q1. Each pixel partition Q1 may include adjacent first pixel units Q11 and second pixel units Q12. The first pixel units Q11 and second pixel units Q12 can form a periodic pixel pattern. The second pixel unit Q12 is formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction. The first pixel unit Q11 includes first-type sub-pixel units P and second-type sub-pixel units Q. The first-type sub-pixel units P include multiple first-type sub-pixels, and the second-type sub-pixel units Q include multiple second-type sub-pixels.

[0118] Within a pixel partition Q1, the first type of sub-pixels P1, S1, and P2 of the first color in the first pixel unit Q11, and the second type of sub-pixels S2, P3, and S3 of the third color in the second pixel unit Q12, can be arranged in a row along a first direction. In other words, within a pixel partition Q1, along the first direction, the first and second types of sub-pixels are arranged alternately, and first and second type sub-pixels of the same color can be placed adjacent to each other, thereby increasing the pixel aperture ratio and achieving a good display effect.

[0119] Within the first pixel unit Q11 or the second pixel unit Q12, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels in the first direction or the second direction, with the first direction perpendicular to the second direction.

[0120] As shown in Figure 3, the first pixel unit Q11 may include one or more first-class sub-pixels of a first color P1, one or more first-class sub-pixels of a second color P2, one or more first-class sub-pixels of a third color P3, one or more second-class sub-pixels of a first color S1, one or more second-class sub-pixels of a second color S2, and one or more second-class sub-pixels of a third color S3. Along a first direction (e.g., row direction), the first-class sub-pixels P1, S1, and P2 are arranged in a row, and the second-class sub-pixels S2, P3, and S3 are arranged in a row. Along a second direction (e.g., column direction), the first-class sub-pixels P1 and S2 are arranged in a column, the second-class sub-pixels S1 and P3 are arranged in a column, and the first-class sub-pixels P2 and S3 are arranged in a column.

[0121] The first type of sub-pixels can be circular. A first-type sub-pixel unit P includes a first-type sub-pixel P1 of a first color, a first-type sub-pixel P2 of a second color, and a first-type sub-pixel P3 of a third color. There can be two first-type sub-pixels of each color, arranged in a row along the second direction. The second type of sub-pixels can be rectangular. A second-type sub-pixel unit S includes a second-type sub-pixel S1 of a first color, a second-type sub-pixel S2 of a second color, and a second-type sub-pixel S3 of a third color. There can be only one second-type sub-pixel of each color.

[0122] It should be noted that in this application, by setting the first type of sub-pixel (i.e., privacy sub-pixel) as a circle, a 360° all-around privacy display can be achieved, which can further increase the aperture ratio.

[0123] For example, the area occupied by two first-class sub-pixels of the same color can be approximately equal to the area occupied by one second-class sub-pixel. Two first-class sub-pixels of the same color are arranged in a row along a second direction, which can be the length direction of a rectangular second-class sub-pixel. Within each pixel unit, by setting two first-class sub-pixels of each color and arranging two first-class sub-pixels of the same color in a row along the second direction, the space within the pixel unit can be fully utilized, and the aperture ratio can be increased.

[0124] In some embodiments, as shown in FIG3, the first pixel unit Q11 can be arranged in a two-row, three-column configuration. Within the first pixel unit Q11, the first row can include three groups of pixel blocks arranged in a row. Each group of pixel blocks can include one or more sub-pixels. For example, the first group of pixel blocks can include two circular first-type sub-pixels of the first color P1, the second group of pixel blocks can include a rectangular second-type sub-pixel of the first color S1, and the third group of pixel blocks can include two circular first-type sub-pixels of the second color P2. The second row can also include three groups of pixel blocks arranged in a row. Each group of pixel blocks can include one or more sub-pixels. For example, the fourth group of pixel blocks can include a rectangular second-type sub-pixel of the second color S2, the fifth group of pixel blocks can include two circular first-type sub-pixels of the third color P3, and the sixth group of pixel blocks can include a rectangular second-type sub-pixel of the third color S3. Within the first pixel unit Q11, the first, second, and third columns may each include two groups of pixel blocks, arranged in a column. Each group of pixel blocks may include one or more sub-pixels. For example, the first group of pixel blocks in the first column may include two circular first-type sub-pixels of the first color P1, and the second group of pixel blocks in the first column may include a rectangular second-type sub-pixel of the second color S2; the first group of pixel blocks in the second column may include a rectangular second-type sub-pixel of the first color S1, and the second group of pixel blocks in the second column may include two circular first-type sub-pixels of the third color P3; the first group of pixel blocks in the third column may include two circular first-type sub-pixels of the second color P2, and the second group of pixel blocks in the third column may include a rectangular second-type sub-pixel of the third color S3.

[0125] In each pixel unit, the first type of sub-pixel P2 of the second color and the second type of sub-pixel S2 of the second color are located on the diagonal of the pixel unit, and the centroid of the second color pixel in the pixel unit coincides with the centroid of the pixel unit. In each first pixel unit, the first type of sub-pixels of the first color, the second color, and the third color are arranged in an inverted acute triangle (such as an inverted equilateral triangle), and in each first pixel unit, the second type of sub-pixels of the first color, the second color, and the third color are arranged in an upright acute triangle (such as an upright equilateral triangle).

[0126] For example, the display panel may include adjacent first pixel partitions and second pixel partitions located in different rows. The first pixel partition includes two adjacent pixel units, and the second pixel partition includes two adjacent pixel units. Subpixels of the same color and type in the four pixel units may be arranged in a parallelogram.

[0127] In each pixel unit, a first-type sub-pixel P1 of the first color and a second-type sub-pixel S1 of the first color are adjacent along a first direction, and in each pixel unit, a first-type sub-pixel P3 of the third color and a second-type sub-pixel S3 of the third color are adjacent along the first direction. It should be understood that adjacent first and second sub-pixels of different types can have the same color, and sub-pixels with the same color can share the opening of the metal mask for color evaporation, thereby increasing the pixel aperture ratio.

[0128] The first type of sub-pixel P2 of the second color of the first pixel unit Q11 and the second type of sub-pixel S2 of the second color of the second pixel unit Q12 are adjacent. It should be understood that the adjacent sub-pixels of the adjacent first pixel unit Q11 and the second pixel unit Q12 can have the same color but different types. Sub-pixels with the same color can share the opening of the metal mask for color evaporation, thereby further increasing the pixel aperture ratio.

[0129] First-class subpixels of the same color have the same shape and area, as do second-class subpixels of the same color. The area of ​​a single first-class subpixel can be smaller than the area of ​​a single second-class subpixel. First-class subpixels of different colors may have unequal areas, as may the areas of second-class subpixels of different colors.

[0130] In some examples, within the first pixel unit Q11 or the second pixel unit Q12, the ratio of the total area of ​​the first type of sub-pixels to the total area of ​​the second type of sub-pixels ranges from 0.2 to 5.

[0131] For example, if the display panel commonly uses a shared display mode, the area of ​​the second type of sub-pixels can be set to be greater than or equal to the area of ​​the second type of sub-pixels. For instance, the ratio of the total area of ​​the first type of sub-pixels to the area of ​​the second type of sub-pixels can range from 0.2 to 1. If the display panel commonly uses a privacy mode (or privacy protection mode), the total area of ​​the first type of sub-pixels can be set to be greater than or equal to the total area of ​​the second type of sub-pixels. For instance, the ratio of the total area of ​​the first type of sub-pixels to the area of ​​the second type of sub-pixels can range from 1 to 5.

[0132] In other words, the area of ​​the first type of subpixels and the second type of subpixels can be set according to the common mode of the display panel. If the common mode is privacy mode, the total area of ​​the first type of subpixels in a pixel unit can be set to be greater than or equal to the total area of ​​the second type of subpixels. If the common mode is sharing mode, the total area of ​​the first type of subpixels in a pixel unit can be set to be less than or equal to the total area of ​​the second type of subpixels. By increasing the area of ​​the commonly used subpixels in the display panel, the aperture ratio can be increased, and the service life of the display panel can be extended.

[0133] The maximum size of the first type of sub-pixel can be less than or equal to the third threshold, which can be, for example, 50 μm.

[0134] The minimum distance between adjacent sub-pixels of the same color is greater than or equal to a first threshold. The minimum distance between adjacent first-color first-class sub-pixels, adjacent second-color first-class sub-pixels, and adjacent third-color first-class sub-pixels can be d1, where d1 is the limit distance of the isolation pillar process. For example, the value of d1 can be 1μm-5μm, that is, the first threshold can be 1μm-5μm.

[0135] The minimum distance between adjacent sub-pixels of different colors is greater than or equal to a second threshold. It should be understood that the minimum distance between adjacent sub-pixels of different colors is greater than or equal to the pixel-defining layer gap (PDL GAP) process limit distance. As shown in Figure 3, the minimum distance between a sub-pixel of the first color and a sub-pixel of the second color, between a sub-pixel of the second color and a sub-pixel of the third color, and between a sub-pixel of the third color and a sub-pixel of the first color is d2, where d2 is the PDL GAP process limit distance. For example, the value of d2 can be 15μm-20μm, meaning the second threshold can be 10μm-20μm.

[0136] In this application, to meet the requirements of processing and manufacturing, the minimum distance between adjacent sub-pixels of the same color satisfies a first threshold. This first threshold can be the limit distance of the isolation pillar process, and this limit distance can be reduced with the improvement of manufacturing processes and methods. To avoid the problem of light crosstalk between sub-pixels of different colors, the minimum distance between adjacent sub-pixels can be limited to satisfy a second threshold. This second threshold can be the limit distance of the PDL GAP process, and this limit distance can be reduced with the improvement of manufacturing processes and methods.

[0137] It should be understood that Figure 3 is only an exemplary illustration of pixel arrangement. In other embodiments, the pixel arrangement can be referred to Figures 4 to 13 below. It should be noted that the following mainly describes the differences from Figure 3, and any parts not described in detail can be referred to the relevant descriptions in Figure 3.

[0138] In some examples, as shown in Figure 4, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12, the first pixel unit Q11 and the second pixel unit Q12 being identical, and the first pixel unit Q11 and / or the second pixel unit Q12 may form a periodic pixel pattern.

[0139] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0140] It should be understood that, relative to Figure 3, in Figure 4, the first pixel unit Q11 and the second pixel unit Q12 are the same.

[0141] In other words, within a pixel partition Q1, the first type of sub-pixels of the first color, the second type of sub-pixels of the first color, and the first type of sub-pixels of the second color included in the first pixel unit Q11, along with the first type of sub-pixels of the first color, the second type of sub-pixels of the first color, and the first type of sub-pixels of the second color included in the second pixel unit Q12, can be arranged in a row along the first direction; similarly, the second type of sub-pixels of the second color, the first type of sub-pixels of the third color, and the second type of sub-pixels of the third color included in the first pixel unit Q11, along with the second type of sub-pixels of the second color, the first type of sub-pixels of the third color, and the second type of sub-pixels of the third color included in the second pixel unit Q12, can also be arranged in a row along the first direction. In other words, within a pixel unit of pixel partition Q1, along the first direction, the first type of sub-pixels and the second type of sub-pixels can be arranged alternately, and the first type of sub-pixels and the second type of sub-pixels of the same color can be set adjacent to each other, thereby increasing the pixel aperture ratio to a certain extent and achieving a good display effect.

[0142] For example, the display panel may include adjacent first pixel partitions and second pixel partitions located in different rows. The first pixel partition includes two adjacent pixel units, and the second pixel partition includes two adjacent pixel units. Subpixels of the same color and type in the four pixel units may be arranged in a square.

[0143] Within a pixel unit, such as the first pixel unit Q11, the pixel arrangement can be referred to the method described in Figure 3, and will not be repeated here.

[0144] In some examples, as shown in Figure 5, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12, which can form a periodic pixel pattern. The second pixel unit Q12 may be formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0145] Within each pixel unit, in a first direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels; in a second direction, there are at least two types of sub-pixels, the colors of which may be the same or different, and the first direction is perpendicular to the second direction.

[0146] It should be understood that, relative to Figure 3, in Figure 5, the color of the sub-pixels in the first pixel unit Q11 or the second pixel unit Q12 changes.

[0147] In other words, within a pixel partition Q1, the first type of sub-pixels of the first color, the second type of sub-pixels of the second color, and the first type of sub-pixels of the second color included in the first pixel unit Q11, along with the second type of sub-pixels of the first color, the first type of sub-pixels of the third color, and the second type of sub-pixels of the third color included in the second pixel unit Q12, can be arranged in a row along the first direction. That is, within a pixel partition Q1, along the first direction, the first type of sub-pixels and the second type of sub-pixels can be arranged alternately. Within a pixel unit of a pixel partition Q1, the first type of sub-pixels and the second type of sub-pixels of the same color can be set adjacent to each other, thereby increasing the pixel aperture ratio to a certain extent and achieving a good display effect.

[0148] For example, the display panel may include adjacent first pixel partitions and second pixel partitions located in different rows. The first pixel partition includes two adjacent pixel units, and the second pixel partition includes two adjacent pixel units. Subpixels of the same color and type in the four pixel units may be arranged in a parallelogram.

[0149] Within a pixel unit, such as within the first pixel unit Q11, along a first direction (e.g., row direction), the first type of sub-pixels of the first color, the second type of sub-pixels of the second color, and the first type of sub-pixels of the second color can be arranged in a row, and the second type of sub-pixels of the first color, the first type of sub-pixels of the third color, and the second type of sub-pixels of the third color can be arranged in a row. Along a second direction (e.g., column direction), the first type of sub-pixels of the first color and the second type of sub-pixels of the first color can be arranged in a column, and the second type of sub-pixels of the second color and the first type of sub-pixels of the third color can be arranged in a column.

[0150] The first type of sub-pixels can be circular, and there can be two of each color, arranged in a row along the second direction. The second type of sub-pixels can be rectangular, and there can be only one of each color.

[0151] It should be understood that other features of the first type of sub-pixel or the second type of sub-pixel can be referred to the relevant descriptions in Figure 3, and will not be repeated here.

[0152] In some examples, as shown in Figure 6, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12, which can form a periodic pixel pattern. The second pixel unit Q12 is formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0153] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0154] It should be understood that, relative to Figure 3, in Figure 6, the first type of sub-pixels can be octagonal, and the second type of sub-pixels can be rectangular. That is, the shape of the first type of sub-pixels can be octagonal, and the number of first type of sub-pixels for each color can be 2; the shape of the second type of sub-pixels can be rectangular, and the number of second type of sub-pixels for each color can be 1.

[0155] It should be understood that the specific pixel arrangement and related descriptions in Figure 6 can be found in the descriptions in Figure 3, and will not be repeated here.

[0156] In some examples, as shown in Figure 7, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12, which can form a periodic pixel pattern. The second pixel unit Q12 is formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0157] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0158] It should be understood that, relative to Figure 3, in Figure 7, the first type of sub-pixels can be elliptical (such as a pill shape), and the second type of sub-pixels can be rectangular. That is, the shape of the first type of sub-pixels can be elliptical, and the number of first type sub-pixels for each color can be 2; the shape of the second type of sub-pixels can be rectangular, and the number of second type sub-pixels for each color can be 1.

The second pixel unit Q12 is formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0161] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0162] It should be understood that, relative to Figure 3, in Figure 8, the first type of sub-pixels can be circular, and the second type of sub-pixels can be hexagonal. That is, the shape of the first type of sub-pixels can be circular, and the number of first type of sub-pixels for each color can be 2; the shape of the second type of sub-pixels can be hexagonal, and the number of second type of sub-pixels for each color can be 1.

[0163] It should be understood that the specific pixel arrangement and related descriptions in Figure 8 can be found in the descriptions in Figure 3, and will not be repeated here.

[0164] In some examples, as shown in Figure 9, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12, which can form a periodic pixel pattern. The second pixel unit Q12 is formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0165] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0166] It should be understood that, relative to Figure 3, in Figure 9, the first type of sub-pixels can be circular, and the second type of sub-pixels can be hexagonal, meaning that the sides of the second type of sub-pixels are concave arcs. In other words, the shape of the first type of sub-pixels can be circular, and the number of first type of sub-pixels for each color can be 2; the shape of the second type of sub-pixels can be hexagonal, and the number of second type of sub-pixels for each color can be 1.

[0167] It should be understood that the specific arrangement of pixels in Figure 9 and related descriptions can be found in the descriptions in Figure 3, and will not be repeated here.

[0168] In some examples, as shown in Figure 10, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12, which can form a periodic pixel pattern. The second pixel unit Q12 is formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0169] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0170] It should be understood that, relative to Figure 3, in Figure 10, the shape of the first type of sub-pixels can be circular, and the number of first type sub-pixels for each color can be 1; the shape of the second type of sub-pixels can be rectangular, and the number of second type sub-pixels for each color can be 1.

[0171] It should be understood that the specific pixel arrangement and related descriptions in Figure 10 can be found in the descriptions in Figure 3, and will not be repeated here.

[0172] In some examples, as shown in Figure 11, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12, which can form a periodic pixel pattern. The second pixel unit Q12 is formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0173] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0174] It should be understood that, relative to Figure 3, in Figure 11, the shape of the first type of sub-pixels can be a rectangle, and the number of first type sub-pixels for each color can be 1; the shape of the second type of sub-pixels can also be a rectangle, and the number of second type sub-pixels for each color can be 1.

[0175] It should be understood that the specific pixel arrangement and related descriptions in Figure 11 can be found in the descriptions in Figure 3, and will not be repeated here.

[0176] In some examples, as shown in Figure 12, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12. The first pixel unit Q11 and the second pixel unit Q12 may be the same, and the first pixel unit Q11 and / or the second pixel unit Q12 may form a periodic pixel pattern.

[0177] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0178] It should be understood that, compared to Figure 3, the arrangement of sub-pixel positions in the first pixel unit Q11 and the second pixel unit Q12 changes in Figure 12.

[0179] Within a pixel partition Q1, the first type of sub-pixels of the first color, the first type of sub-pixels of the second color, and the second type of sub-pixels of the first color included in the first pixel unit Q11, along with the first type of sub-pixels of the first color, the first type of sub-pixels of the second color, and the second type of sub-pixels of the first color included in the second pixel unit Q12, can be arranged in a row along the first direction. In other words, within a pixel partition Q1, along the first direction, some first type and second type sub-pixels can be arranged alternately; within a pixel unit of a pixel partition Q1, some first type and second type sub-pixels of the same color can be arranged adjacently, thereby increasing the pixel aperture ratio to a certain extent and achieving a good display effect.

[0180] For example, the display panel may include adjacent first pixel partitions and second pixel partitions located in different rows. The first pixel partition includes two adjacent pixel units, and the second pixel partition includes two adjacent pixel units. Subpixels of the same color and type in the four pixel units may be arranged in a square.

[0181] Within a pixel unit, such as within the first pixel unit Q11, the first type of sub-pixels of the first color, the first type of sub-pixels of the second color, and the second type of sub-pixels of the first color can be arranged in a row in the first direction (e.g., the row direction), and the second type of sub-pixels of the second color, the second type of sub-pixels of the third color, and the first type of sub-pixels of the third color can be arranged in a row in the first direction. The first type of sub-pixels of the first color and the second type of sub-pixels of the second color can be arranged in a column in the second direction (e.g., the column direction), and the first type of sub-pixels of the second color and the second type of sub-pixels of the third color can be arranged in a column in the second direction.

[0182] In Figure 12, the first type of sub-pixels can be circular, with two of each color, arranged in a row along the second direction. The second type of sub-pixels can be rectangular, with one of each color. In each pixel unit, the first type of sub-pixels of the first, second, and third colors are arranged in an inverted obtuse triangle, and in each first pixel unit, the second type of sub-pixels of the first, second, and third colors are arranged in an upright obtuse triangle.

[0183] It should be understood that other features of the first type of sub-pixel or the second type of sub-pixel can be referred to the relevant descriptions in Figure 3, and will not be repeated here.

[0184] In some examples, as shown in Figure 13, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 including a first pixel unit Q11 and a second pixel unit Q12, which can form a periodic pixel pattern. The second pixel unit Q12 may be formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0185] Within each pixel unit, in either a first direction or a second direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels, with the first direction perpendicular to the second direction.

[0186] It should be understood that, compared to Figure 3, the arrangement of sub-pixel positions in the first pixel unit Q11 and the second pixel unit Q12 changes in Figure 13.

[0187] Within a pixel partition Q1, the first type of sub-pixels of the first color, the second type of sub-pixels of the first color, and the second type of sub-pixels of the second color included in the first pixel unit Q11, along with the second type of sub-pixels of the third color, the first type of sub-pixels of the second color, and the first type of sub-pixels of the third color included in the second pixel unit Q12, can be arranged in a row along the first direction. In other words, within a pixel partition Q1, along the first direction, some of the first type of sub-pixels and second type of sub-pixels can be arranged alternately; within a pixel unit of a pixel partition Q1, some of the first type of sub-pixels and second type of sub-pixels of the same color can be arranged adjacently, thereby increasing the pixel aperture ratio to a certain extent and achieving a good display effect.

[0188] For example, the display panel may include adjacent first pixel partitions and second pixel partitions located in different rows. The first pixel partition includes two adjacent pixel units, and the second pixel partition includes two adjacent pixel units. Subpixels of the same color and type in the four pixel units may be arranged in a parallelogram.

[0189] Within a pixel unit, such as within the first pixel unit Q11, the first type of sub-pixels of the first color, the second type of sub-pixels of the first color, and the second type of sub-pixels of the second color can be arranged in a row in the first direction; the second type of sub-pixels of the third color, the first type of sub-pixels of the second color, and the first type of sub-pixels of the third color can also be arranged in a row in the first direction. The first type of sub-pixels of the first color and the second type of sub-pixels of the third color can be arranged in a column in the second direction; the second type of sub-pixels of the first color and the first type of sub-pixels of the second color can also be arranged in a column in the second direction.

[0190] In Figure 13, the first type of sub-pixels can be circular, with two of each color, arranged in a row along the second direction. The second type of sub-pixels can be rectangular, with one of each color. In each pixel unit, the first type of sub-pixels of the first, second, and third colors are arranged in an upright obtuse triangle, while in each first pixel unit, the second type of sub-pixels of the first, second, and third colors are arranged in an inverted obtuse triangle.

[0191] It should be understood that other features of the first type of sub-pixel or the second type of sub-pixel can be referred to the relevant descriptions in Figure 3, and will not be repeated here.

[0192] Figure 14 is a schematic diagram of pixel partitioning of a display panel provided in an embodiment of this application.

[0193] As shown in Figure 14, the light-emitting layer 210 includes multiple pixel partitions Q1. Each pixel partition Q1 includes adjacent first pixel units Q11 and second pixel units Q12, wherein the first pixel units Q11 and second pixel units Q12 can form a periodic pixel pattern. The first pixel units Q11 and second pixel units Q12 can be the same or different. That is, the arrangement of sub-pixels in the second pixel unit Q12 is the same as the arrangement of sub-pixels in the first pixel unit Q11, or the arrangement of sub-pixels in the second pixel unit Q12 is the same as the arrangement of sub-pixels in the first pixel unit Q11 after being rotated by a preset angle. The preset angle can be, for example, 90°, 180°, 270°, 360°, etc. For example, the first pixel units Q11 and second pixel units Q12 in the pixel partition Q1 are arranged adjacent to each other along a first direction, and the arrangement of sub-pixels in the second pixel unit Q12 is mirror-symmetrical to the arrangement of sub-pixels in the first pixel unit Q11 about the first direction.

[0194] In Figure 14, the first pixel unit Q11 is different from the second pixel unit Q12. The second pixel unit Q12 can be obtained by rotating the first pixel unit Q11 by a preset angle in a certain direction. That is to say, the arrangement of the sub-pixels in the second pixel unit Q12 is the same as the arrangement of the sub-pixels after rotating the first pixel unit Q11 by a preset angle.

[0195] Within each pixel unit, in a first direction (e.g., row direction), there are at least two colors of sub-pixels and at least two types of sub-pixels; in a second direction (e.g., column direction), there is at least one column of sub-pixels of the same type but different colors. The two types of sub-pixels can be understood as including both first-type and second-type sub-pixels, that is, including both privacy sub-pixels and shared sub-pixels. For example, within each pixel unit, in the first direction (e.g., row direction), at least one color among the red, green, and blue sub-pixels is repeated, and both first-type and second-type sub-pixels exist simultaneously; in the second direction (e.g., column direction), at least one column contains both first-type and second-type sub-pixels, and the colors of the first-type and second-type sub-pixels are different.

[0196] For example, at least two types of subpixels may include a first type of subpixel and a second type of subpixel, and different types of subpixels may emit light independently in different modes. For example, in the first mode, the emissive layer may illuminate the first type of subpixel independently; in the second mode, the emissive layer may illuminate the second type of subpixel independently.

[0197] In some examples, the first type of subpixel can be a privacy subpixel, and the second type of subpixel can be a shared subpixel; the first mode can be a privacy mode (or privacy mode), and the second mode can be a shared mode.

[0198] In other examples, the first mode can be the display mode corresponding to the first color gamut, and the second mode can be the display mode corresponding to the second color gamut, where the first and second color gamuts are different. That is, the first and second types of subpixels may not be used to switch between privacy and sharing, but rather to display different color gamuts; in other words, the first and second types of subpixels can correspond to subpixels displayed in different color gamuts. For example, when displaying only the first type of subpixel, it can correspond to the first color gamut; when displaying only the second type of subpixel, it can correspond to the second color gamut.

[0199] In some other examples, the first mode can be an anti-glare mode and the second mode can be a non-anti-glare mode. In the first mode, the light-emitting layer can light up the first type of sub-pixels individually, so that the display panel has an anti-glare function. In the second mode, the light-emitting layer can light up the second type of sub-pixels individually. At this time, the display panel may not have an anti-glare function.

[0200] The display panel provided in this application can adopt the following pixel arrangement: in the first direction (e.g., row direction), it can have at least two colors and at least two types of sub-pixels; in the second direction (e.g., column direction), it can have sub-pixels of different colors but the same type; it can achieve an alternating arrangement of adjacent first-type and second-type sub-pixels in the first and second directions, resulting in a larger opening area of ​​the metal mask for fabricating the pixel arrangement structure, which can improve the pixel aperture ratio, increase the light-emitting area, and improve the display brightness, lifespan, and screen resolution of the display panel. Furthermore, within each pixel unit, the first-type and second-type sub-pixels are evenly distributed, making full use of the space. And when displaying the first-type or second-type sub-pixels individually, sub-pixels are displayed in both the row and column directions, thus eliminating the problem of black lines and achieving a better display effect.

[0201] For example, as shown in Figure 14, the first pixel unit Q11 and the second pixel unit Q12 can be pixel units with two rows and three columns (2×3). Within the first pixel unit Q11, in the first direction (e.g., the row direction), the first row includes a first-type sub-pixel P1 of a first color, a first-type sub-pixel P1 of a second color, and a second-type sub-pixel S1 of a first color; the second row includes a first-type sub-pixel P3 of a third color, a second-type sub-pixel S2 of a second color, and a second-type sub-pixel S3 of a third color. In the second direction (e.g., the column direction), the first column includes a first-type sub-pixel of a first color and a first-type sub-pixel of a third color; the second column includes a first-type sub-pixel of a second color and a second-type sub-pixel of a second color; and the third column includes a second-type sub-pixel of a first color and a second-type sub-pixel of a third color.

[0202] In other words, the row direction of the first pixel unit Q11 includes both first-type sub-pixels and second-type sub-pixels, and the row direction of the first pixel unit Q11 includes either first-type sub-pixels of at least two colors or second-type sub-pixels of at least two colors; the column direction of the first pixel unit Q11 includes at least one column of first-type sub-pixels or second-type sub-pixels of the same type but different colors.

[0203] For example, the first type of sub-pixels of the first color, second color, and third color in the first pixel unit Q11 can be arranged in an inverted right-angled triangle, and the second type of sub-pixels of the first color, second color, and third color in the first pixel unit Q11 can be arranged in an upright right-angled triangle. The first type of sub-pixels of the first color, second color, and third color in the second pixel unit Q12 can be arranged in an upright right-angled triangle, and the second type of sub-pixels of the first color, second color, and third color in the second pixel unit Q12 can be arranged in an inverted right-angled triangle.

[0204] It should be understood that the above mainly introduces the differences between Figure 14 and Figure 2. The similarities between the two will not be repeated. For details, please refer to the relevant description in Figure 2.

[0205] Figures 15 and 16 are schematic diagrams illustrating the pixel arrangement shown in Figure 14 in the embodiments of this application.

[0206] In some examples, as shown in Figure 15, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 may include a first pixel unit Q11 and a second pixel unit Q12, and the first pixel unit Q11 and the second pixel unit Q12 may form a periodic pixel pattern. The first pixel unit Q11 includes a first type of sub-pixel unit and a second type of sub-pixel unit, and the second pixel unit Q12 is formed by mirror-flipping the first pixel unit Q11 by 180° along a second direction.

[0207] Within each pixel unit, in a first direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels; in a second direction, there are at least two types of sub-pixels of different colors, and the first direction is perpendicular to the second direction.

[0208] Within a pixel partition Q1, the first type of sub-pixels of the first color, the first type of sub-pixels of the third color, and the second type of sub-pixels of the third color included in the first pixel unit Q11, and the first type of sub-pixels of the second color, the second type of sub-pixels of the second color, and the second type of sub-pixels of the first color included in the second pixel unit Q12, can be arranged in a row along the first direction. In other words, within a pixel partition Q1, along the first direction, some first type and second type sub-pixels can be arranged alternately, and some first type and second type sub-pixels of the same color can be arranged adjacently. Within a pixel unit of pixel partition Q1, along the first direction, some first type and second type sub-pixels of the same color can be arranged adjacently; this can increase the pixel aperture ratio to a certain extent, resulting in a better display effect.

[0209] For example, the display panel may include adjacent first pixel partitions and second pixel partitions located in different rows. The first pixel partition includes two adjacent pixel units, and the second pixel partition includes two adjacent pixel units. Subpixels of the same color and type in the four pixel units may be arranged in a parallelogram.

[0210] Within a pixel unit, such as within the first pixel unit Q11, the first type of sub-pixels of the first color, the first type of sub-pixels of the third color, and the second type of sub-pixels of the third color can be arranged in a row in the first direction; the first type of sub-pixels of the second color, the second type of sub-pixels of the second color, and the second type of sub-pixels of the first color can be arranged in a row in the first direction. The first type of sub-pixels of the first color and the first type of sub-pixels of the second color can be arranged in a column in the second direction; the first type of sub-pixels of the third color and the second type of sub-pixels of the second color can be arranged in a column in the second direction; and the second type of sub-pixels of the third color and the second type of sub-pixels of the first color can be arranged in a column in the second direction.

[0211] In Figure 15, the first type of sub-pixels can be circular, with two of each color, arranged in a row along the second direction. The second type of sub-pixels can be rectangular, with one of each color. In each first pixel unit Q11, the first type of sub-pixels of the first, second, and third colors are arranged in an inverted right-angled triangle, while the second type of sub-pixels of the first, second, and third colors are arranged in an upright right-angled triangle. In each second pixel unit Q12, the first type of sub-pixels of the first, second, and third colors are arranged in an upright right-angled triangle, while the second type of sub-pixels of the first, second, and third colors are arranged in an inverted right-angled triangle.

[0212] In some examples, as shown in Figure 16, the display panel may include multiple pixel partitions Q1, each pixel partition Q1 may include a first pixel unit Q11 and a second pixel unit Q12, the first pixel unit Q11 and the second pixel unit Q12 are the same, and the first pixel unit Q11 and / or the second pixel unit Q12 may form a periodic pixel pattern.

[0213] Within each pixel unit, in a first direction, there are at least two types of sub-pixels of different colors and at least two types of sub-pixels; in a second direction, there are at least two types of sub-pixels of different colors, and the first direction is perpendicular to the second direction.

[0214] It should be understood that, relative to Figure 15, in Figure 16, the first pixel unit Q11 is the same as the second pixel unit Q12.

[0215] In other words, within a pixel partition Q1, the first type of sub-pixels of the first color, the first type of sub-pixels of the third color, and the second type of sub-pixels of the third color included in the first pixel unit Q11, and the first type of sub-pixels of the first color, the first type of sub-pixels of the third color, and the second type of sub-pixels of the third color included in the second pixel unit Q12, can be arranged in a row along the first direction; the second type of sub-pixels of the second color, the second type of sub-pixels of the second color, and the second type of sub-pixels of the first color included in the first pixel unit Q11, and the first type of sub-pixels of the second color, the second type of sub-pixels of the second color, and the second type of sub-pixels of the first color included in the second pixel unit Q12, can also be arranged in a row along the first direction. That is, within a pixel partition Q1, along the first direction, some first type of sub-pixels and second type of sub-pixels can be arranged alternately; within a pixel unit of pixel partition Q1, along the first direction, some first type of sub-pixels and second type of sub-pixels of the same color can be arranged adjacently; this can increase the pixel aperture ratio to a certain extent, resulting in a good display effect.

[0216] For example, the display panel may include adjacent first pixel partitions and second pixel partitions located in different rows. The first pixel partition includes two adjacent pixel units, and the second pixel partition includes two adjacent pixel units. Subpixels of the same color and type in the four pixel units may be arranged in a square.

[0217] Within a pixel unit, such as the first pixel unit Q11, the pixel arrangement can be referred to the manner described in Figures 14 and 15, and will not be repeated here.

[0218] The various implementation schemes of pixel arrangement provided in the embodiments of this application have been described in detail above with reference to Figures 2 to 16. It should be understood that in the above schemes, multiple light-shielding layers can be used to restrict the light emission direction of the light-emitting layer 210, thereby enabling the switching between privacy mode and sharing mode.

[0219] It should be noted that the pixel partitions and pixel units described in the above embodiments are merely illustrative examples, and this application is not limited to the above-described partitioning methods. It should be understood that the pixel partitions or pixel units shown in Figures 3 to 13, 15, and 16 can also be recombinated to form new pixel arrangements. For example, pixel partition Q1 shown in Figure 3 can be combined with pixel partition Q1 shown in Figure 15; or, for another example, the first pixel unit Q11 shown in Figure 4 can be recombinated with the second pixel unit Q12 shown in Figure 16 to form a new pixel partition Q1, etc.

[0220] It should also be understood that the pixel arrangement provided in this application satisfies the following rules: within a pixel unit, there are at least two colors and at least two types of sub-pixels along the first direction, and at least two types of sub-pixels along the second direction; or, within a pixel unit, there are at least two colors and at least two types of sub-pixels along the first direction, and sub-pixels of different colors but the same type along the second direction; this application does not specifically limit how to divide pixel units, and the above is mainly illustrated by example with reference to Figures 2 to 16.

[0221] Figures 17 and 18 show schematic diagrams of using multiple light-shielding layers to define the light-emitting layer.

[0222] Referring to Figures 1 and 17, multiple light-shielding layers can be used to define the light emission direction of the light-emitting layer 210. Each of the multiple light-shielding layers corresponds one-to-one with a first-type sub-pixel. The second light-shielding layer 530 can be the outermost layer of the multiple light-shielding layers. The second light-shielding layer 530 has multiple openings, and both the first-type and second-type sub-pixels are located within the openings of the second light-shielding layer 530. In other words, the orthographic projection of the first-type sub-pixel (i.e., privacy sub-pixels) onto the substrate 100 lies within the opening of the orthographic projection of the second light-shielding layer 530 onto the substrate 100, and the orthographic projection of the second-type sub-pixel (i.e., shared sub-pixels) onto the substrate 100 lies within the opening of the orthographic projection of the second light-shielding layer 530 onto the substrate 100.

[0223] It should be understood that when specifically setting the opening shape of the multi-layer light-shielding layer, it can be designed according to the shape of the first type of sub-pixels and the second type of sub-pixels. For example, if the first type of sub-pixels is circular, the opening of the light-shielding layer corresponding to each of the first type of sub-pixels can be a concentric circular hole, that is, the opening of the second light-shielding layer 530 corresponding to the first type of sub-pixels can be circular, and the minimum distance between the first type of sub-pixels and the edge of the circular hole is the process limit distance. As shown in Figure 17, the minimum distance d3 between the first type of sub-pixels and the second light-shielding layer 530 is the process limit distance, and the value of d3 can be 0.1μm.

[0224] For example, if the second type of sub-pixel is rectangular, the light-shielding layer opening corresponding to the second type of sub-pixel can be a concentric rectangular hole, that is, the opening of the second light-shielding layer 530 and the second type of sub-pixel can be rectangular, and the minimum distance d4 between the second type of sub-pixel and the edge of the rectangular hole should be greater than or equal to d3, and the value of d4 can be 4μm.

[0225] In some examples, the first light-shielding layer 510 may have multiple first openings and multiple third openings. The first openings correspond to a first type of sub-pixel, and the third openings correspond to a second type of sub-pixel. The shape of the first opening is the same as the shape of the first type of sub-pixel, and the shape of the third opening is the same as the shape of the second type of sub-pixel. For example, the first type of sub-pixel is circular, the second type of sub-pixel is rectangular, the projection of the first opening is a circular hole, the projection of the third opening is a rectangular hole, the minimum distance of the first type of sub-pixel from the edge of the circular hole is a process limit distance (e.g., 0.1 μm), and the minimum distance of the second type of sub-pixel from the edge of the rectangular hole is greater than this process limit distance (e.g., 4 μm).

[0226] In some examples, the second light-shielding layer 530 may have multiple second openings and multiple fourth openings. The second openings correspond to first-type sub-pixels, and the fourth openings correspond to second-type sub-pixels. The shapes of the second openings and fourth openings are the same as the shapes of the first-type sub-pixels. For example, the first-type sub-pixels are circular, the second-type sub-pixels are rectangular, the projection of the second opening is a circular hole, and the projection of the fourth opening is a rectangular hole. The minimum distance between the first-type sub-pixel and the edge of the circular hole is a process limit distance (e.g., 0.1 μm), and the minimum distance between the second-type sub-pixel and the edge of the rectangular hole is greater than this process limit distance (e.g., 4 μm).

[0227] In some embodiments, as shown in FIG18, the multiple light-shielding parts of each light-shielding pattern can be arranged in a triangular pattern in the pixel unit (such as the right-angled triangle, acute-angled triangle, or obtuse-angled triangle mentioned above), and the multiple light-shielding layers can correspond one-to-one with the first type of sub-pixels. The multiple light-shielding layers can be disposed only on the outer periphery of the first type of sub-pixels (i.e., privacy sub-pixels), and the outer periphery of the second type of sub-pixels (i.e., shared sub-pixels) does not need to be disposed with multiple light-shielding layers. The second light-shielding layer 530 can be disposed on the outer periphery of the first type of sub-pixels (i.e., privacy sub-pixels), and the second light-shielding layer 530 can have a circular opening, the center of which overlaps with the center of the first type of sub-pixels. The minimum distance d3 from the first type of sub-pixels to the edge of the circular opening is the process limit distance, and the value of d3 can be 0.1μm.

[0228] For example, the first light-shielding layer 510 may be disposed only on the outer periphery of the first type of sub-pixels. That is, the orthographic projection of the first light-shielding layer 510 on the substrate 100 is located outside the orthographic projection of the first type of sub-pixels on the substrate 100, and the first light-shielding layer 510 may not be disposed at the corresponding position of the second type of sub-pixels. The first light-shielding layer 510 may have multiple first openings, and the shape of the first openings is the same as the shape of the first type of sub-pixels. For example, the minimum distance between the edge of the circle formed by the orthographic projection of the first type of sub-pixels on the substrate 100 and the orthographic projection of the first light-shielding layer 510 on the substrate 100 is the process limit distance (i.e., d3).

[0229] For example, the second light-shielding layer 530 may be disposed only on the outer periphery of the first type of sub-pixels. That is, the orthographic projection of the second light-shielding layer 530 on the substrate 100 is located outside the orthographic projection of the first type of sub-pixels on the substrate 100, and the second light-shielding layer 530 may not be disposed at the corresponding position of the second type of sub-pixels. The second light-shielding layer 530 may have multiple second openings, and the shape of the second openings is the same as the shape of the first type of sub-pixels. For example, the minimum distance between the edge of the circle formed by the orthographic projection of the first type of sub-pixels on the substrate 100 and the orthographic projection of the second light-shielding layer 530 on the substrate 100 is the process limit distance (i.e., d3).

[0230] In the display panel provided in this application, the emission angle of the first type of sub-pixels can be limited by the first light-shielding layer 510 and the second light-shielding layer 530, thereby limiting the user's field of vision. For example, by limiting the size of the second opening of the second light-shielding layer 530, the user cannot observe the content on the display panel when the viewing angle is greater than 45°, thus achieving a privacy protection function. Furthermore, by setting a double-layer light-shielding layer, light leakage from the first type of sub-pixels can also be avoided, thus achieving all-around privacy protection.

[0231] Figures 19 and 20 show a schematic diagram of the stacking of a display panel within a single pixel unit.

[0232] As shown in Figure 19, within the first pixel unit Q11, the display panel may include a substrate 100, a light-emitting pixel layer 200, a thin-film encapsulation layer 300, a touch layer 400, and a light-confining layer 500. The light-emitting pixel layer 200 includes a light-emitting layer 210 and a pixel defining layer 220. The light-emitting layer 210 includes two first-type sub-pixels 201 of a second color and one second-type sub-pixel 202 of a third color. The light-confining layer 500 may include a first light-shielding layer 510, a second light-shielding layer 530, a dielectric layer 520 between the first light-shielding layer 510 and the second light-shielding layer 530, and a surface encapsulation layer 540 covering the second light-shielding layer 530.

[0233] It should be understood that the opening size of the first light-shielding layer 510 is smaller than or equal to the opening size of the second light-shielding layer 530. That is, along the direction away from the substrate 100, the outermost end point of the outermost light-shielding part (i.e., the second light-shielding layer 530) is on a straight line with the left end point of the remaining light-shielding parts (i.e., the first light-shielding layer 510) and the left end point of the first type of sub-pixel 201; or, the outermost end point of the outermost light-shielding part (i.e., the second light-shielding layer 530) is located to the right of the straight line containing the left end point of the remaining light-shielding parts (i.e., the first light-shielding layer 510) and the left end point of the first type of sub-pixel 201.

[0234] The outermost light-shielding portion (i.e., the second light-shielding layer 530) corresponding to each of the first type of sub-pixels absorbs at least a portion of the light emitted from the first side of the first type of sub-pixels whose emission angle is greater than the first emission angle θ1 and less than the second emission angle θ2. The remaining light-shielding portions (i.e., the first light-shielding layer 510) corresponding to each of the first type of sub-pixels, excluding the outermost light-shielding portion, absorb all remaining light rays whose emission angle is greater than the second emission angle θ2 that are not absorbed by the outermost light-shielding portion (i.e., the second light-shielding layer 530). The remaining light-shielding portions corresponding to each of the first type of sub-pixels absorb at least a portion or all of the light rays emitted from the second side of the first type of sub-pixels whose emission angle is greater than the first emission angle θ1 and less than the third emission angle θ3, where the third emission angle θ3 is greater than or equal to the total internal reflection angle.

[0235] As shown in Figure 19, the display panel can employ a double-layer light-shielding layer, namely a first light-shielding layer 510 and a second light-shielding layer 530. Along the direction away from the substrate, the left end of the second light-shielding layer 530 restricts the minimum internal emission light angle to θ1, and the right end of the first light-shielding layer 510 prevents large-angle light leakage from the privacy sub-pixel, with θ3 being greater than or equal to the total internal reflection angle; the light emission angle of the line connecting the left end of the privacy sub-pixel and the left end of the first light-shielding layer 510 is θ2, and the right end of the second light-shielding layer 530 is located at or beyond θ2 for the emitted light.

[0236] It should be understood that the maximum emission angle of the light rays emitted from the first type of sub-pixel 201 Less than or equal to the maximum emission angle of the light rays emitted from the second type of sub-pixel 202 Alternatively, the maximum emission angle of the light rays emitted from the second type of sub-pixel 202. The maximum emission angle of the light rays emitted from the first type of sub-pixel 201 is greater than or equal to that of the first type of sub-pixel 201.

[0237] In the display panel provided in this application, the first type of sub-pixel can be a privacy sub-pixel, the second type of sub-pixel can be a shared sub-pixel, and the maximum emission angle of the light emitted from the shared sub-pixel is... The maximum emission angle of the light emitted from the privacy subpixel can be greater than or equal to that of the privacy subpixel. This allows the viewing range of shared subpixels to be greater than that of privacy subpixels. In other words, the second type of subpixels has a wide viewing angle, while the first type of subpixels has a relatively small viewing angle, thus achieving the function of privacy protection. For example, when the viewing angle is greater than 45°, the user cannot observe the content on the display panel.

[0238] For example, the first light-shielding layer 510 can be entirely disposed on the side of the touch layer 400 away from the substrate 100. The maximum diameter of the opening on the first light-shielding layer 510 corresponding to the first type of sub-pixel 201 is smaller than the maximum diameter of the opening on the first light-shielding layer 510 corresponding to the second type of sub-pixel 202. The second light-shielding layer 520 can be disposed only in the area corresponding to the first type of sub-pixel 201, and the area corresponding to the second type of sub-pixel 202 can be left undisposed of the second light-shielding layer 520, thereby expanding the light emission range of the second type of sub-pixel 202 and expanding the visible range of the normal area or shared area.

[0239] In some examples, as shown in FIG20, the display panel may include a substrate 100, a light-emitting layer 200, an adhesive layer 310, a functional layer 600, a first light-shielding layer 510, a dielectric layer 520, a second light-shielding layer 530, and a surface encapsulation layer 540 stacked together. That is, the adhesive layer 310 is located between the light-emitting layer 200 and the functional layer 600, and the functional layer 600 is located between the adhesive layer 310 and the first light-shielding layer 510. The functional layer 600 may include an intermediate layer 320, an adhesive layer 330, and a touch layer 400. It should be understood that the adhesive layer 310, the intermediate layer 320, and the adhesive layer 330 can form the aforementioned thin-film encapsulation layer 300, and the material of the intermediate layer 320 can be inkjet printing ink (IJP).

[0240] The refractive index of the multiple film layers included in the display panel can range from 1.2 to 2.3. For example, the refractive index of the adhesive layer 310 can be 1.5.

[0241] The functional layer 600 may include multiple film layers, and the dielectric layer 520 between the first light-shielding layer 510 and the second light-shielding layer 530 may also include multiple film layers.

[0242] For example, the dashed lines in Figure 20 show the emitted light under normal conditions (i.e., the refractive index of the films in the functional layer 600 and the dielectric layer 520 is not changed), and the solid lines in Figure 20 show the emitted light when the refractive index of at least one film in the functional layer 600 and the dielectric layer 520 is changed.

[0243] In some embodiments, at least one film layer in the functional layer 600 has a refractive index greater than that of the adhesive layer 310.

[0244] For example, as shown in Figure 20, the refractive index of the intermediate layer 320 can be greater than that of the adhesive layer 310. Therefore, when light emitted from the light-emitting layer 200 enters the intermediate layer 320 from the adhesive layer 310, the emitted light rays will be deflected in the normal direction (see the enlarged schematic diagram circled in the circle). This reduces the width of the first light-shielding layer 510 corresponding to the first type of sub-pixel 201 (as shown in Figure 20, the width of the first light-shielding layer 510 can be reduced by width L1), increasing the pixel's occupied space and thus improving the pixel aperture ratio. Simultaneously, the angle of the emitted light rays from the second type of sub-pixel 202 can be increased, further expanding the visible range of the shared area.

[0245] In some embodiments, at least one film layer in the functional layer 600 has a refractive index greater than that of the adhesive layer 310, and at least one film layer in the dielectric layer 520 has a refractive index less than that of the adhesive layer 310.

[0246] For example, as shown in FIG20, the refractive index of the dielectric layer 520 can be less than that of the adhesive layer 310. Therefore, when the light emitted from the light-emitting layer 200 enters the dielectric layer 520 from the functional layer 600, the emitted light will be deflected away from the normal direction, which can also reduce the width of the second light-shielding layer 520 corresponding to the first type of sub-pixel 201 (as shown in FIG20, the width of the second light-shielding layer 520 can be reduced by width L2), thereby increasing the pixel occupied space and thus improving the pixel aperture ratio.

[0247] In other words, by setting at least one film layer in the functional layer 600 to have a refractive index greater than that of the adhesive layer 310, and setting at least one film layer in the dielectric layer 520 to have a refractive index less than that of the adhesive layer 310, the width of the first light-shielding layer 510 and the second light-shielding layer 520 corresponding to a single pixel can be reduced, thereby increasing the pixel's occupied space and further improving the pixel aperture ratio.

[0248] In some embodiments, at least one film layer in the functional layer 600 has a refractive index greater than that of the adhesive layer 310, a first region of at least one film layer in the dielectric layer 520 has a refractive index less than that of the adhesive layer 310, and a second region of at least one film layer in the dielectric layer 520 has a refractive index greater than or equal to that of the adhesive layer 310. The first region is the region in the dielectric layer 520 corresponding to the first type of sub-pixel 201, and the second region is the region in the dielectric layer 520 corresponding to the second type of sub-pixel 202.

[0249] It should be understood that by setting at least one film layer in the functional layer 600 to have a refractive index greater than that of the adhesive layer 310, and by setting at least one film layer in the medium layer 520 to have a refractive index less than that of the region corresponding to the first type of sub-pixel 201, the widths of the first light-shielding layer 510 and the second light-shielding layer 520 corresponding to a single pixel can be reduced simultaneously, thereby further increasing the pixel's occupied space and thus further increasing the pixel aperture ratio. Furthermore, by setting at least one film layer in the functional layer 600 to have a refractive index greater than that of the adhesive layer 310, and by setting at least one film layer in the medium layer 520 to have a refractive index greater than or equal to that of the region corresponding to the second type of sub-pixel 202, the angle of light emitted from the second type of sub-pixel 202 can be increased, further increasing the visible range of the shared area.

[0250] Figures 21 to 24 show schematic diagrams of the display panel's display effect in different modes.

[0251] In this application, first-type sub-pixels of the same color in each pixel unit share the same anode, second-type sub-pixels of the same color share the same anode, and first-type and second-type sub-pixels of the same color share the same driving circuit. Active switching between a first mode, a second mode, and a third mode can be achieved using a circuit switch. The first mode can be a privacy mode, while the second and third modes can be shared modes. The privacy pixel unit and the shared pixel unit in each pixel unit receive the first driving signal and the second driving signal, respectively.

[0252] For example, as shown in Figure 21, when the full-screen first mode is enabled, when the first driving signal is input, only the privacy pixel unit sub-pixel of each pixel unit is turned on and illuminated, while the shared pixel units are not turned on at all.

[0253] For example, as shown in Figure 22, when the second full-screen mode is enabled, when the second driving signal is input, only the shared pixel unit sub-pixels of each pixel unit are turned on and illuminated, while the privacy pixel units are not turned on at all.

[0254] For example, as shown in Figure 23, when the full-screen third mode is enabled, the input of the first driving signal and the second driving signal causes the privacy pixel unit and the shared pixel unit sub-pixel in each pixel unit to be turned on and emit light.

[0255] It should be noted that in this application, the display panel can display three different light emission modes, and the three light emission modes can be actively switched. The display resolution remains unchanged in single mode, and there is no black line problem, thus improving the display effect.

[0256] It should be understood that in this application, some areas can be enabled as the first mode (protection against peeping only in the privacy information display area, such as the password area / privacy ticket number / privacy QR code area, etc.), while other areas are enabled as the second or third mode, and the pixel units in different areas receive the driving signals of the corresponding modes.

[0257] In some embodiments, the third-mode diagonal line display can simultaneously and individually activate the shared sub-pixels and privacy sub-pixels of adjacent pixel units, as shown in Figure 24. Some pixel units only activate either the shared sub-pixel or the privacy sub-pixel, while others activate both. It should be understood that by adopting the display mode shown in Figure 24, the jagged edges of the display panel can be reduced, and the display effect can be improved.

[0258] In addition, this application also provides a display device, which may include a display panel as shown in Figures 1 to 19 above. The display device may be, for example, a mobile phone, tablet, personal computer, monitor, television, vehicle display, or other device with a display panel. This application does not limit the scope of the application.

[0259] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
