Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] With the development of display technology, consumers have increasingly higher requirements for display effects. Among these, resolution, contrast ratio, and color are common parameters for evaluating display effects, and the arrangement of subpixels in a display device directly affects the quality of these parameters. Taking organic light-emitting diode (OLED) display panels as an example, the denser the subpixel arrangement in the display panel, the higher the resolution of the display panel. However, when the subpixels are densely arranged, light-blocking structures are needed to avoid light crosstalk between subpixels, thereby improving contrast ratio. However, when the subpixels are densely arranged and light-blocking structures are set between subpixels, the probability of diffraction problems in the display panel increases, which in turn degrades the color expression of the display panel. Summary of the Invention

[0003] In view of this, embodiments of this application provide a display panel and a display device to solve the above problems.

[0004] In a first aspect, this application provides a display panel including a plurality of pixel units; each pixel unit includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel, the edge shapes of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel are all non-linear; wherein, in the same pixel unit, the first color sub-pixel and the second color sub-pixel are arranged along a first direction, the third color sub-pixel and the area between the first color sub-pixel and the second color sub-pixel are arranged along a second direction, and the third color sub-pixel does not overlap with at least one of the first color sub-pixel and the second color sub-pixel in the second direction.

[0005] Secondly, this application provides a display device, including a display panel as provided in the first aspect.

[0006] In the pixel units of the display panel provided in this application embodiment, there is no parallel region extending along the first direction between the third color sub-pixel and at least one of the first color sub-pixel and the second color sub-pixel, thereby alleviating the diffraction problem easily caused by the narrow width of the region between the third color sub-pixel and the first color sub-pixel and the second color sub-pixel. Furthermore, the edges of the shapes of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel are non-linear structures, which can further reduce the possibility of the third color sub-pixel being parallel to the first color sub-pixel and the second color sub-pixel.

Detailed Implementation

[0009] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0014] It should be understood that although terms such as "first," "second," etc., may be used to describe openings in the embodiments of this application, these should not be limited to these terms. These terms are only used to distinguish openings from each other. For example, without departing from the scope of the embodiments of this application, a first opening may also be referred to as a second opening, and similarly, a second opening may also be referred to as a first opening. Through careful and in-depth research, the applicant of this application has provided a solution to the problems existing in the prior art.

[0015] Figure 1 This is a schematic diagram of a display panel provided in an embodiment of this application. Figure 1 As shown, the display panel 01 includes a plurality of pixel units 10, each pixel unit 10 including a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13; among the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13, one is a red sub-pixel, one is a green sub-pixel, and one is a blue sub-pixel. For example, the first color sub-pixel 11 is a red sub-pixel, the second color sub-pixel 12 is a green sub-pixel, and the third color sub-pixel 13 is a blue sub-pixel; or, the first color sub-pixel 11 is a red sub-pixel, the second color sub-pixel 12 is a blue sub-pixel, and the third color sub-pixel 13 is a green sub-pixel.

[0016] The display panel 01 provided in this application embodiment can be an organic light-emitting display panel 01, in which each sub-pixel is an organic light-emitting diode and the position of the sub-pixel can be defined by the opening filled with organic light-emitting material in the pixel definition layer; the display panel 01 provided in this application embodiment can also be a liquid crystal display panel 01, in which the position of the sub-pixel can be defined by the opening filled with color resist in the black matrix or by the pixel electrode; the display panel 01 provided in this application embodiment can also be a Micro-LED display panel 01, in which the position of the sub-pixel can be defined by the position of the Micro-LED; the display panel 01 provided in this application embodiment can also be other forms of display panel 01.

[0017] In the same pixel unit 10, the first color sub-pixel 11 and the second color sub-pixel 12 are arranged along the first direction Y, and the area between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 is arranged along the second direction X. Therefore, the first color sub-pixel 11 and the second color sub-pixel 12 in the same pixel unit 10 overlap in the first direction Y, and the area between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 in the same pixel unit 10 overlaps in the second direction X. Furthermore, among the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 included in the same pixel unit 10, the third color sub-pixel 13 does not overlap with at least one of the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X. The first direction Y intersects the second direction X; specifically, the first direction Y and the second direction X can be perpendicular to each other. Figure 1 The first direction Y shown can be vertical, and the second direction X can be horizontal. For example, as... Figure 1 As shown, in the same pixel unit 10, the first color sub-pixel 11 and the second color sub-pixel 12 are arranged in the vertical direction, and the area between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 overlaps in the horizontal direction, and the third color sub-pixel 13 does not overlap with the first color sub-pixel 11 and the second color sub-pixel 12 in the horizontal direction.

[0018] Furthermore, the edge shapes of the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 in the display panel 01 provided in this application embodiment are all non-linear, which reduces the possibility of adjacent edges of different color sub-pixels in the same pixel unit 10 being parallel, that is, reducing the length of parallel adjacent edges of different color sub-pixels, thereby reducing the area where the distance between different color sub-pixels is too small. It should be noted that the shape of a sub-pixel can be the projection shape of the sub-pixel in the direction perpendicular to the plane where the display panel 01 is located, then the edge of the sub-pixel is the edge of the projection of the sub-pixel in the direction perpendicular to the plane where the display panel 01 is located.

[0019] Figure 2 This is a schematic diagram of a pixel unit related to an embodiment of this application.

[0020] like Figure 2As shown, the third color sub-pixel 13 in the same pixel unit 10 overlaps with the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X, and the third color sub-pixel 13, the first color sub-pixel 11, and the second color sub-pixel 12 are all rectangular structures. Specifically, the middle region where the third color sub-pixel 13 and the first color sub-pixel 11 are parallel has a smaller width in the horizontal direction and a larger length in the vertical direction, making it prone to diffraction. Similarly, the middle region where the third color sub-pixel 13 and the second color sub-pixel 12 are parallel has a smaller width in the horizontal direction and a larger length in the vertical direction, making it prone to diffraction. In particular, when the area between sub-pixels includes a light-shielding structure such as a black matrix or a mesh-like touch electrode metal line on the side facing the light-shielding surface of the display panel 01, it is equivalent to the middle regions where the third color sub-pixel 13 and the first color sub-pixel 11 are parallel, and the middle regions where the third color sub-pixel 13 and the second color sub-pixel 12 are parallel, having a narrower width and a longer length on the side facing the light-shielding surface of the display panel 01. This easily causes diffraction and thus affects the display effect.

[0021] In the display panel 01 provided in this embodiment, which includes pixel units 10, please refer to... Figure 1 There is no parallel region extending along the first direction Y between the third color sub-pixel 13 and at least one of the first color sub-pixel 11 and the second color sub-pixel 12, thereby alleviating the diffraction problem easily caused by the narrow width of the region between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12. Furthermore, the edges of the shapes of the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 are non-linear structures, which can further reduce the possibility of the third color sub-pixel 13 being parallel to the first color sub-pixel 11 and the second color sub-pixel 12. In addition, the non-linear edges of the shapes of the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 can be implemented, such as... Figure 1 As shown, the edge shape of the third color sub-pixel 13 can be such that the closer it is to the first color sub-pixel 11 in the first direction Y, the farther it is from the first color sub-pixel 11 in the second direction X; the edge shape of the second color sub-pixel 12 can be such that the closer it is to the second color sub-pixel 12 in the first direction Y, the farther it is from the second color sub-pixel 12 in the second direction X. That is, by increasing the distance between the third color sub-pixel 13 and the first color sub-pixel 11 and the distance between the third color sub-pixel 13 and the second color sub-pixel 12, the risk of diffraction phenomenon is reduced.

[0022] Figure 3 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application. Figure 4 for Figure 3A schematic cross-sectional view along the S1-S2 direction.

[0023] Combination Figure 3 and Figure 4 As shown, the display panel 01 includes a light-emitting material layer 100 and a pixel definition layer 200. The pixel definition layer 200 includes multiple openings, and the light-emitting material layer 100 includes a light-emitting material. The openings of the pixel definition layer 200 are filled with the light-emitting material. The shape of the openings included in the pixel definition layer 200 defines the shape of the sub-pixels. Therefore, when the pixel unit 10 includes a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13, the pixel definition layer 200 includes a first opening 21 defining the area where the first color sub-pixel 11 is located, a second opening 22 defining the area where the second color sub-pixel 12 is located, and a third opening 23 defining the area where the third color sub-pixel 13 is located. The luminescent material included in the luminescent material layer 100 can be an organic luminescent material, and the luminescent material layer 100 includes luminescent materials capable of emitting different colors of light. Therefore, when the pixel unit 10 includes a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13, the luminescent material layer 100 includes a first color luminescent material 111, a second color luminescent material 121, and a third color luminescent material 131, and the first opening 21 of the pixel definition layer 200 is filled with the first color luminescent material 111, the second opening 22 is filled with the second color luminescent material 121, and the third opening 23 is filled with the third color luminescent material 131. In this embodiment, the edge shapes of the first opening 21, the second opening 22, and the third opening 23 are non-linear, so that the edge shapes of the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 are non-linear, wherein, as shown... Figure 4 As shown, the edge shape of the opening can be the shape of the upper edge of the opening.

[0024] In the fabrication of organic light-emitting materials, a photomask is used, and the cutout portion of the photomask is aligned with the opening in the pixel definition layer 200 so that the light-emitting material can be deposited through the cutout portion of the photomask into the opening of the pixel definition layer 200. However, due to limitations in alignment accuracy and deposition process, in order to ensure that the opening of the pixel definition layer 200 is completely filled with light-emitting material, the area of ​​the cutout portion of the photomask is designed to be larger than the area of ​​its corresponding opening. Therefore, the light-emitting material layer 100 includes light-emitting material blocks of different colors, and the light-emitting material blocks include portions that fill the openings of the pixel definition layer 200 and portions that are located outside the openings. When the pixel unit 10 includes a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13, the light-emitting material layer 100 includes a first color light-emitting material block 110, a second color light-emitting material block 120, and a third color light-emitting material block 130. The first color sub-pixel 11 includes a portion of the first color light-emitting material block 110 located inside the first opening 21 and a portion 112 located outside the first opening 21. The second color sub-pixel 12 includes a portion of the second color light-emitting material block 120 located inside the second opening 22 and a portion 122 located outside the second opening 22. The third color sub-pixel 13 includes a portion of the third color light-emitting material block 130 located inside the third opening 23 and a portion 132 located outside the third opening 23.

[0025] The edges of the first color luminescent material block 110, the second color luminescent material block 120, and the third color luminescent material block 130 can all be rectangular. Understandably, the cutout portion in the mask used during luminescent material deposition, aligned with the opening in the pixel definition layer 200, is rectangular. Therefore, when depositing the luminescent material included in the sub-pixels of the display panel 01, the mask structure used is simple, and the process requirements for mask fabrication are relatively low, making it easy to implement.

[0026] An achievable technical solution, such as Figure 3As shown, in the same pixel unit 10, the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 correspond to the first color emitting material block 110, the second color emitting material block 120, and the third color emitting material block 130, respectively. The second center line L2 of the third color emitting material block 130 is parallel to the boundary line of the first color emitting material block 110 and the second color emitting material block 120. Furthermore, the second center line L2 of the edge shape of the third color emitting material block 130 is parallel to the second direction X and passes through the midpoint of the third color emitting material block 130. Since the regions of the third color sub-pixel 13, the first color sub-pixel 11, and the second color sub-pixel 12 in the same pixel unit 10 overlap in the second direction Y, that is, the regions of the third opening 23, the first opening 21, and the second opening 22 overlap in the second direction Y, when preparing the luminescent material, the second center line L2 of the third color luminescent material block 130 coincides with the boundary line of the first color luminescent material block 110 and the second color luminescent material block 120, which can effectively reduce the risk of the second center line L2 of the third color luminescent material block 130 deviating from the third opening 23 in the second direction Y, thereby avoiding the problem of missing colors.

[0027] Figure 5 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application. Figure 6 for Figure 5 A schematic cross-sectional view along the S1-S2 direction.

[0028] In a feasible technical solution, combining Figure 5 and Figure 6 The display panel 01 also includes a light filter layer 300, which further includes a color resist block 31. At least one of the first opening 21, the second opening 22, and the third opening 23 overlaps with the color resist block 31 in a direction Z perpendicular to the plane of the display panel 01. Figure 5 and Figure 6 As shown, the first color resist 311 overlaps with the first opening 21 in the direction Z perpendicular to the plane of the display panel 01; the second color resist 312 overlaps with the second opening 22 in the direction Z perpendicular to the plane of the display panel 01; and the third color resist 323 overlaps with the third opening 23 in the direction Z perpendicular to the plane of the display panel 01. The color resist 31 can filter light to make the color of the light purer, and it can also reduce the amount of ambient light incident on the sub-pixels of the display panel to improve the display effect.

[0029] In addition to the color resist block 31, the filter layer typically includes a black matrix 32. The black matrix includes a cutout portion, and at least a portion of the color resist block 31 fills the cutout portion of the black matrix 32. In the embodiments of this application, the arrangement and shape design of the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 in the pixel unit 10 can effectively alleviate the diffraction problem that occurs when light passes through the black matrix.

[0030] Next, the shape of the sub-pixels in pixel unit 10 will be described. It should be noted that, provided there is no technical conflict, new solutions obtained by combining the following embodiments of the shape of the sub-pixels of pixel unit 10 with any of the above embodiments are also within the scope of protection of this application. The edge shape of the first color sub-pixel 11 may include arcs and / or elliptical arcs, so the shape of the first color sub-pixel 11 can be a circle, an ellipse, an egg shape, etc. For example, Figure 1 , Figure 3 and Figure 5 As shown, the shape of the first color sub-pixel 11 can be circular.

[0031] The edge shape of the second color sub-pixel 12 can include arcs and / or elliptical arcs, so the shape of the second color sub-pixel 12 can be a circle, an ellipse, an egg shape, etc. For example, Figure 1 , Figure 3 and Figure 5 As shown, the shape of the second color sub-pixel 12 can be circular.

[0032] The edge shape of the third color sub-pixel 13 may include arcs and / or elliptical arcs, so the shape of the third color sub-pixel 13 may be a circle, an ellipse, an egg shape, etc.

[0033] In one embodiment of this application, such as Figure 1 , Figure 3 and Figure 5 As shown, the edge shape of the third color sub-pixel 13 is circular, and the circular shape of the third color sub-pixel 13 is relatively easy to implement. Furthermore, please continue to refer to... Figure 1 , Figure 3 and Figure 5As shown, in the same pixel unit 10, the point A1 of the circular third color sub-pixel 13, which is closest to the column containing the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X, can overlap with the area between the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X. Therefore, the distance between other points in the circular third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 is larger than that between point A1 and the first color sub-pixel 11 and the second color sub-pixel 12. This can effectively prevent the distance between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 from being too small, thereby effectively improving the diffraction problem.

[0034] Figure 7 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0035] In one embodiment of this application, such as Figure 7 As shown, the edge shape of the third color sub-pixel 13 is elliptical, and the major axis of the ellipse is parallel to the first direction Y. The length of the third color sub-pixel 13 in the first direction Y is greater than its length in the second direction X. Therefore, the third color sub-pixel 13 in the same pixel unit 10 can perform better color rendering with the first color sub-pixel 11 and the second color sub-pixel 12, and avoids the increase in the width of the pixel unit 10 in the second direction X, which would affect the arrangement of the pixel unit 10. Similarly, as Figure 7 As shown, in the same pixel unit 10, the point A2 of the elliptical third color sub-pixel 13, which is closest to the column containing the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X, can overlap with the area between the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X. Therefore, the distance between other points in the elliptical third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 is larger than that between point A2 and the first color sub-pixel 11 and the second color sub-pixel 12. This can effectively prevent the distance between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 from being too small, thereby effectively improving the diffraction problem.

[0036] Figure 8 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0037] In one embodiment of this application, such as Figure 8As shown, the edge shape of the third color sub-pixel 13 includes a circular arc 13a and an elliptical arc 13b arranged along the first direction Y. The circular arc 13a and the elliptical arc 13b can form an oval shape when they meet. The major axis of the ellipse corresponding to the elliptical arc 13b is parallel to the first direction Y. Therefore, the length direction of the oval shape formed by the connection of the circular arc 13a and the elliptical arc 13b is parallel to the first direction Y, and the width direction is parallel to the second direction X. On the one hand, the third color sub-pixel 13 in the same pixel unit 10 can perform better color rendering with the first color sub-pixel 11 and the second color sub-pixel 12, and avoids the increase in the width of the pixel unit 10 in the second direction X, which would affect the arrangement of the pixel unit 10. On the other hand, based on the brightness characteristics of the first color sub-pixel 11 and the second color sub-pixel 12, the portion of the third color sub-pixel 13 including the arc 13a can be set to be close to the first color sub-pixel 11, and the portion including the elliptical arc 13b can be set to be close to the second color sub-pixel 12, or the portion of the third color sub-pixel 13 including the elliptical arc 13b can be set to be close to the first color sub-pixel 11, and the portion including the arc 13a can be set to be close to the second color sub-pixel 12, to achieve a better white balance. Similarly, as... Figure 8 As shown, in the same pixel unit 10, the point A3 of the oval-shaped third color sub-pixel 13, which is closest to the column containing the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X, can overlap with the area between the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X. Therefore, the distance between other points in the oval-shaped third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 is larger than that between point A3 and the first color sub-pixel 11 and the second color sub-pixel 12. This can effectively prevent the distance between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 from being too small, thereby effectively improving the diffraction problem.

[0038] In one embodiment of this application, the edge shape of the first color sub-pixel 11 is circular, and / or, the edge shape of the second color sub-pixel 12 is circular. Furthermore, the edge shapes of the first color sub-pixel 11 and the second color sub-pixel 12 in the same pixel unit 10 can be the same, for example, as shown below. Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the edge shapes of the first color sub-pixel 11 and the second color sub-pixel 12 are both circular; the edge shapes of the first color sub-pixel 11 and the second color sub-pixel 12 in the same pixel unit 10 may also be different, for example, one is circular and the other is other shapes.

[0039] In this embodiment, the edge shape of the third color sub-pixel 13 in the same pixel unit 10 can be circular, elliptical, or an egg-like shape including contiguous circular arcs 13a and elliptical arcs 13b. For example, as Figure 1 , Figure 3 and Figure 5 As shown, the edge shape of the first color sub-pixel 11 is circular, the edge shape of the second color sub-pixel 12 is circular, and the edge shape of the third color sub-pixel 13 is circular; for example, as Figure 7 As shown, the edge shape of the first color sub-pixel 11 is circular, the edge shape of the second color sub-pixel 12 is circular, and the edge shape of the third color sub-pixel 13 is elliptical; for example, as Figure 8 As shown, the edge shape of the first color sub-pixel 11 is circular, the edge shape of the second color sub-pixel 12 is circular, and the edge shape of the third color sub-pixel 13 is an egg-like shape where the arc 13a and the elliptical arc 13b meet.

[0041] In one embodiment of this application, such as Figures 9-11 As shown, the edge shape of the first color sub-pixel 11 is elliptical, and the major axis of the ellipse is parallel to the second direction X; and / or, the edge shape of the second color sub-pixel 12 is elliptical, and the major axis of the ellipse is parallel to the second direction X. Since the first color sub-pixel 11 and the second color sub-pixel 12 in the same pixel unit 10 are arranged along the first direction Y, if the major axis of the elliptical sub-pixel is parallel to the first direction Y, the pixel unit 10 occupies a large width in the first direction Y, which is not conducive to the color rendering of different color sub-pixels in the pixel unit 10. However, in this embodiment, when the edge shape of at least one of the first color sub-pixel 11 and the second color sub-pixel 12 is elliptical, its arrangement is reasonably designed, which is beneficial to ensuring the color rendering effect of different color sub-pixels in the pixel unit 10, and the area occupied by the pixel unit 10 is reasonable in both the first direction Y and the second direction X. In addition, the edge shape of the first color sub-pixel 11 and the edge shape of the second color sub-pixel 12 in the same pixel unit 10 can be the same, for example, as Figures 9-11 As shown, the edge shapes of the first color sub-pixel 11 and the second color sub-pixel 12 are both elliptical; the edge shapes of the first color sub-pixel 11 and the second color sub-pixel 12 in the same pixel unit 10 may also be different, for example, one is elliptical and the other is other shapes.

[0042] In this embodiment, the edge shape of the third color sub-pixel 13 in the same pixel unit 10 can be circular, elliptical, or include contiguous circular arcs 13a and elliptical arcs 13b. For example, as Figure 9 As shown, the edge shape of the first color sub-pixel 11 is elliptical, the edge shape of the second color sub-pixel 12 is elliptical, and the edge shape of the third color sub-pixel 13 is circular; for example, as Figure 10 As shown, the edge shape of the first color sub-pixel 11 is elliptical, the edge shape of the second color sub-pixel 12 is elliptical, and the edge shape of the third color sub-pixel 13 is elliptical; for example, as Figure 11 As shown, the edge shape of the first color sub-pixel 11 is elliptical, the edge shape of the second color sub-pixel 12 is elliptical, and the edge shape of the third color sub-pixel 13 is an egg-like shape formed by the connection of the circular arc 13a and the elliptical arc 13b.

[0043] Figure 12 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application. Figure 13 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application. Figure 14 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0044] In one embodiment of this application, such as Figures 12-14 As shown, the edge shape of the first color sub-pixel 11 includes a circular arc 11a and an elliptical arc 11b arranged along the second direction X, and / or the edge shape of the second color sub-pixel 12 includes a circular arc 12a and an elliptical arc 12b arranged along the second direction X; the major axis of the ellipse corresponding to the elliptical arc 12b is parallel to the second direction X. Since the first color sub-pixel 11 and the second color sub-pixel 12 in the same pixel unit 10 are arranged along the first direction Y, if the major axis of the sub-pixel with a shape similar to an egg is parallel to the first direction Y, the pixel unit 10 occupies a large width in the first direction Y, which is not conducive to the color rendering of different color sub-pixels in the pixel unit 10. However, in this embodiment, when the edge shape of at least one of the first color sub-pixel 11 and the second color sub-pixel 12 is similar to an egg, the alignment arrangement is reasonably designed, which is beneficial to ensuring the color rendering effect of different color sub-pixels in the pixel unit 10, and the area occupied by the pixel unit 10 is reasonable in both the first direction Y and the second direction X. Furthermore, the edge shape of the first color sub-pixel 11 and the edge shape of the second color sub-pixel 12 in the same pixel unit 10 can be the same, for example, as Figures 12-14As shown, the edge shapes of the first color sub-pixel 11 and the second color sub-pixel 12 both include adjacent circular arcs and elliptical arcs; the edge shapes of the first color sub-pixel 11 and the second color sub-pixel 12 in the same pixel unit 10 may also be different, for example, one includes a goose-egg-like shape with circular arcs and elliptical arcs and the other is other shapes.

[0045] In this embodiment, the edge shape of the third color sub-pixel 13 in the same pixel unit 10 can be circular, elliptical, or include contiguous circular arcs 13a and elliptical arcs 13b. For example, as Figure 12 As shown, the edge shape of the first color sub-pixel 11 is an oval shape including contiguous circular arcs 11a and elliptical arcs 11b; the edge shape of the second color sub-pixel 12 is an oval shape including circular arcs 12a and elliptical arcs 12b; and the edge shape of the third color sub-pixel 13 is circular; for example, as Figure 13 As shown, the edge shape of the first color sub-pixel 11 is an oval shape including contiguous circular arcs 11a and elliptical arcs 11b; the edge shape of the second color sub-pixel 12 is an oval shape including circular arcs 11a and elliptical arcs 11b; and the edge shape of the third color sub-pixel 13 is elliptical; for example, as Figure 14 As shown, the edge shape of the first color sub-pixel 11 is an oval shape including the connecting arc 11a and elliptical arc 11b; the edge shape of the second color sub-pixel 12 is an oval shape including the arc 12a and elliptical arc 12b; and the edge shape of the third color sub-pixel 13 is an oval shape formed by the connection of the arc 13a and the elliptical arc 13b.

[0046] Furthermore, in one technical solution, such as Figures 12-14 As shown, when the edge shape of at least one of the first color sub-pixel 11 and the second color sub-pixel 12 is an oval shape including arcs and elliptical arcs arranged along the second direction X, the part including the arc is located on the side of the elliptical arc facing the third color sub-pixel 13 in the same pixel unit 10 in the second direction X, so as to achieve a better rendering effect with the third color sub-pixel 13 and reduce the risk of color mixing with sub-pixels in other pixel units 10.

[0047] Next, the arrangement of sub-pixels in pixel unit 10 will be described. It should be noted that, provided there is no technical conflict, new solutions obtained by combining the following embodiments of the sub-pixel arrangement of pixel unit 10 with any of the above embodiments are also within the scope of protection of this application. For example, unless otherwise specified, the following embodiments are described with the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 having circular edges. However, these embodiments are also applicable to cases where the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 are elliptical, egg-shaped, or similar.

[0048] Figure 15 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0049] In one embodiment of this application, within the same pixel unit 10, the third color sub-pixel 13 does not overlap with the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X. That is, as shown... Figure 15 As shown, the distance between the third color sub-pixel 13 and the first color sub-pixel 11 in the first direction Y is D1, and the distance between the third color sub-pixel 13 and the second color sub-pixel 12 in the first direction Y is D2, where D1 > 0 and D2 > 0. When the third color sub-pixel 13 in the same pixel unit 10 does not overlap with the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X, there is no parallel region extending along the first direction Y between the third color sub-pixel 13 and the first color sub-pixel 11, and there is no parallel region extending along the first direction Y between the third color sub-pixel 13 and the second color sub-pixel 12. This ensures that there is a relatively wide distance between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12, thereby effectively mitigating the diffraction problem.

[0050] In one technical solution, such as Figure 15 As shown, D1=D2, meaning that the distance between the third color sub-pixel 13 and the first color sub-pixel 11 in the same pixel unit 10 along the first direction Y is approximately equal to the distance between the third color sub-pixel 13 and the second color sub-pixel 12 along the first direction Y. Considering the influence of unavoidable factors such as process errors, D1 and D2 are equal within the error range, and in the actual display panel 01, D1 is approximately equal to D2. In this technical solution, D1=D2 allows the third color sub-pixel 13 to achieve better color rendering with both the first color sub-pixel 11 and the second color sub-pixel.

[0051] Figure 16 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application. Figure 17 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0052] In one technical solution, such as Figure 16 and Figure 17 As shown, D1 < D2 or D1 > D2, meaning that the distance between the third color sub-pixel 13 and the first color sub-pixel 11 in the same pixel unit 10 along the first direction Y is designed to be unequal to the distance between the third color sub-pixel 13 and the second color sub-pixel 12 along the first direction Y. The difference between D1 and D2 can be 4μm-5μm. In this technical solution, the distance between the third color sub-pixel 13 and the first color sub-pixel 11 and the second color sub-pixel 12 along the first direction Y can be set according to the brightness characteristics of the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13, ensuring that the third color sub-pixel 13 can achieve reasonable color rendering with the first color sub-pixel 11 and the second color sub-pixel 12 to obtain better white balance.

[0053] For example, such as Figure 16 As shown, the third color sub-pixel 13 includes an arc 13a and an elliptical arc 13b, with the elliptical arc 13b located on the side of the arc 13a facing the first color sub-pixel 11 in the first direction Y. Therefore, the distance D1 between the third color sub-pixel 13 and the first color sub-pixel 11 in the same pixel unit 10 in the first direction Y is less than the distance D2 between the third color sub-pixel 13 and the second color sub-pixel 12 in the first direction Y. In this embodiment, the distance between the portion of the third color sub-pixel 13 corresponding to the elliptical arc 13b and the first color sub-pixel 11 in the second direction X is greater than the distance between the portion corresponding to the arc 13a and the second color sub-pixel 12 in the second direction X. By setting the third color sub-pixel 13 to be closer to the first color sub-pixel 11 in the first direction Y, the third color sub-pixel 13 can effectively perform color rendering with the first color sub-pixel 11, thereby facilitating white balance.

[0054] For example, such as Figure 17As shown, the third color sub-pixel 13 includes an arc 13a and an elliptical arc 13b, with the elliptical arc 13b located on the side of the arc 13a facing the second color sub-pixel 12 in the first direction Y. Therefore, the distance D2 between the third color sub-pixel 13 and the second color sub-pixel 12 in the same pixel unit 10 in the first direction Y is less than the distance D1 between the third color sub-pixel 13 and the first color sub-pixel 11 in the first direction Y. In this embodiment, the distance between the portion of the third color sub-pixel 13 corresponding to the elliptical arc 13b and the second color sub-pixel 11 in the second direction X is greater than the distance between the portion corresponding to the arc 13a and the first color sub-pixel 11 in the second direction X. By setting the third color sub-pixel 13 to be closer to the second color sub-pixel 12 in the first direction Y, the third color sub-pixel 13 can effectively perform color rendering with the second color sub-pixel 12, thereby facilitating white balance.

[0055] In one technical solution, such as Figures 15 to 17 As shown, the first center line L1 of the edge shape of the third color sub-pixel 13 is parallel to the second direction X. It should be noted that the first center line L1 is a virtual straight line that passes through the first color sub-pixel 11. In the same pixel unit 10, the distance between the first center line of the third color sub-pixel 13 and the first color sub-pixel 11 in the first direction Y is d1, and the distance between the first center line of the third color sub-pixel 13 and the second color sub-pixel 12 in the first direction Y is d2, where d1 = d2. That is, the distance between the center point of the third color sub-pixel 13 and the first color sub-pixel 11 in the first direction Y in the same pixel unit 10 is equal to the distance between the center point of the third color sub-pixel 13 and the second color sub-pixel 12 in the first direction Y. Considering the influence of unavoidable factors such as process errors, d1 and d2 are equal within the error range. In the actual display panel 01, d1 is approximately equal to d2.

[0056] Figure 18 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application. Figure 19 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0057] One embodiment of this application, such as Figure 18 and Figure 19 As shown, in the same pixel unit 10, the third color sub-pixel 13 overlaps with one of the first color sub-pixel 11 and the second color sub-pixel 12 in the second direction X, but does not overlap with the other in the second direction X. The sub-pixel that overlaps with the third color sub-pixel 13 in the second direction X can achieve better color rendering with the third color sub-pixel 13 within the pixel unit 10. For example, as... Figure 18As shown, in the same pixel unit 10, the third color sub-pixel 13 partially overlaps with the first color sub-pixel 11 in the second direction X, but does not overlap with the second color sub-pixel 12 in the second direction X. For example, as Figure 19 As shown, in the same pixel unit 10, the third color sub-pixel 13 and the second color sub-pixel 12 partially overlap in the second direction X, but do not overlap with the first color sub-pixel 11 in the second direction X.

[0058] In one technical solution, within the same pixel unit 10, the area of ​​the sub-pixel overlapping with the third color sub-pixel 13 in the second direction X is larger than the area of ​​the sub-pixel that does not overlap with the third color sub-pixel 13 in the second direction X. Therefore, considering at least one factor such as white balance, brightness, and luminous efficiency, when one of the first color sub-pixel 11 and the second color sub-pixel 12 is designed to have a larger area and the other a smaller area, the distance between the larger and smaller areas in the second direction X is relatively small when the larger and smaller sub-pixels overlap in the second direction X. This avoids the pixel unit 10 from having an excessively large width in the first direction Y when the first color sub-pixel 11 and the second color sub-pixel 12 are arranged in the first direction Y. For example, as... Figure 18 As shown, the third color sub-pixel 13 overlaps with the first color sub-pixel 11 in the second direction X, but does not overlap with the second color sub-pixel 12 in the second direction X. The area of ​​the first color sub-pixel 11 is larger than the area of ​​the second color sub-pixel 12. For example, as... Figure 19 As shown, the third color sub-pixel 13 overlaps with the second color sub-pixel 12 in the second direction X, but does not overlap with the first color sub-pixel 11 in the second direction X. The area of ​​the second color sub-pixel 12 is larger than the area of ​​the first color sub-pixel 11.

[0059] Figure 20 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0060] In the same pixel unit 10, the first color sub-pixel 11 includes a first endpoint P1 close to the second color sub-pixel 12, and the second color sub-pixel 12 includes a second endpoint P2 close to the first color sub-pixel 11. The first endpoint P1 can be the point in the first color sub-pixel 11 that is closest to the second color sub-pixel 12 in the same pixel unit 10 along the first direction Y, and the second endpoint P2 can be the point in the second color sub-pixel 12 that is closest to the first color sub-pixel 11 in the same pixel unit 10 along the first direction Y. The third color sub-pixel 13 includes a third endpoint P3 and a fourth endpoint P4 opposite each other along the first direction Y. The third endpoint P3 and the fourth endpoint P4 are the two opposite endpoints of the third color sub-pixel 13 that are farthest apart along the first direction Y. The distance between the third endpoint P3 and the first endpoint P1 in the first direction Y is less than the distance between the third endpoint P3 and the second endpoint P2 in the first direction Y, and the distance between the fourth endpoint P4 and the second endpoint P2 in the first direction Y is less than the distance between the fourth endpoint P4 and the first endpoint P1 in the first direction Y. Figure 20 As shown, the third endpoint P3 is closer to the first color sub-pixel 11 in the first direction Y than the fourth endpoint P4, and the third endpoint P3 is the farthest point of the third color sub-pixel 13 in the first direction Y. The fourth endpoint P4 is closer to the second color sub-pixel 12 in the first direction Y than the third endpoint P3, and the fourth endpoint P4 is the farthest point of the third color sub-pixel 13 in the first direction Y.

[0061] In one technical solution, such as Figure 20 As shown, when the third color sub-pixel 13 and the second color sub-pixel 12 in the same pixel unit 10 overlap in the second direction X but do not overlap with the first color sub-pixel 11 in the second direction X, the distance between the third endpoint P3 and the first endpoint P1 in the first direction Y is D1, and the distance between the fourth endpoint P4 and the second endpoint P2 in the first direction Y is D2, where D1=D2. That is, the width of the overlapping portion of the second color sub-pixel 12 and the third color sub-pixel 13 in the second direction X along the first direction Y is equal to the distance between the first color sub-pixel 11 and the third color sub-pixel 13 in the first direction Y. In this technical solution, the color rendering effect between the second color sub-pixel 12 and the third color sub-pixel 13 can be improved, and the distance between the first color sub-pixel 11 and the second color sub-pixel 12 included in the same pixel unit 10 is not reduced due to the overlap of the second color sub-pixel 12 and the third color sub-pixel 13 in the second direction X, thus minimizing the diffraction problem caused by the small distance between sub-pixels.

[0062] Furthermore, when the third color sub-pixel 13 in the same pixel unit 10 overlaps with the first color sub-pixel 11 in the second direction X but does not overlap with the second color sub-pixel 12 in the second direction X, the width of the overlapping portion of the first color sub-pixel 11 and the third color sub-pixel 13 in the second direction X along the first direction Y can also be equal to the distance between the second color sub-pixel 12 and the third color sub-pixel 13 in the first direction Y.

[0063] In this technical solution, the edge shape of the third color sub-pixel 13 can be a relatively regular circle or ellipse.

[0064] Figure 21 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0065] In one technical solution, such as Figure 21 As shown, when the third color sub-pixel 13 and the second color sub-pixel 12 overlap in the second direction X but do not overlap with the first color sub-pixel 11 in the second direction X, the distance between the third endpoint P3 and the first endpoint P1 in the first direction Y is D1, and the distance between the fourth endpoint P4 and the second endpoint P2 in the first direction Y is D2, where D1 < D2. That is, the width of the overlapping portion of the second color sub-pixel 12 and the third color sub-pixel 13 in the second direction X along the first direction Y is greater than the distance between the first color sub-pixel 11 and the third color sub-pixel 13 in the first direction Y. In this technical solution, although the first color sub-pixel 11 and the third color sub-pixel 13 do not overlap in the second direction X, the distance between the first color sub-pixel 11 and the third color sub-pixel 13 in the first direction Y is relatively close, which is beneficial to the rendering of these two color sub-pixels and can avoid the first color sub-pixel 11 and the second color sub-pixel 12 being too far apart in the first direction Y, thus affecting the color rendering between them.

[0066] Furthermore, when the third color sub-pixel 13 in the same pixel unit 10 overlaps with the first color sub-pixel 11 in the second direction X but does not overlap with the second color sub-pixel 12 in the second direction X, the width of the overlapping portion of the first color sub-pixel 11 and the third color sub-pixel 13 in the second direction X along the first direction Y can also be greater than the distance between the second color sub-pixel 12 and the third color sub-pixel 13 in the first direction Y.

[0067] Figure 22 This is a schematic diagram of a pixel unit in a display panel provided in an embodiment of this application.

[0068] In one possible implementation, such as Figure 22As shown, when the third color sub-pixel 13 and the second color sub-pixel 12 in the same pixel unit 10 overlap in the second direction X but do not overlap with the first color sub-pixel 11 in the second direction X, the edge shape of the third color sub-pixel 13 includes a circular arc 13a and an elliptical arc 13b arranged along the first direction Y, and the width of the elliptical arc 13b in the first direction Y is greater than the width of the circular arc 13a in the first direction Y. The circular arc 13a is located on the side of the elliptical arc 13b away from the fourth endpoint P4 in the first direction Y. That is, the longer and thinner part of the third color sub-pixel 13 corresponding to the elliptical arc 13b overlaps with a sub-pixel in the same pixel unit 10 in the second direction X, and the shorter and wider part corresponding to the circular arc 13a does not overlap with the sub-pixel in the same pixel unit 10 in the second direction X. In this implementation, the irregularly shaped third color sub-pixel 13 can achieve good rendering effects with both the first color sub-pixel 11 and the second color sub-pixel 12.

[0069] Furthermore, when the third color sub-pixel 13 in the same pixel unit 10 overlaps with the first color sub-pixel 11 in the second direction X but does not overlap with the second color sub-pixel 12 in the second direction X, the arc 13a in the edge shape of the third color sub-pixel 13 can be located on the side of the elliptical arc 13b away from the third endpoint P3 in the first direction Y.

[0070] In one embodiment of this application, such as Figure 3 , Figure 5 , Figures 7-17 As shown, the area of ​​the first color sub-pixel 11 is the same as the area of ​​the second color sub-pixel 12.

[0071] In one embodiment of this application, please refer to Figure 18 and Figure 19 In the first color sub-pixel 11 and the second color sub-pixel 12, the area of ​​one is larger than the area of ​​the other. For example, as... Figure 18 As shown, the area of ​​the first color sub-pixel 11 is larger than the area of ​​the second color sub-pixel 12; for example, as Figure 19 As shown, the area of ​​the second color sub-pixel 12 is larger than the area of ​​the first color sub-pixel 11.

[0072] In one embodiment of this application, please refer to Figure 18 and Figure 19 The area of ​​the third color sub-pixel 13 is the same as the area of ​​the larger of the first color sub-pixel 11 and the second color sub-pixel 12. For example, as Figure 18 As shown, the area of ​​the first color sub-pixel 11 is larger than the area of ​​the second color sub-pixel 12, and the area of ​​the first color sub-pixel 11 is the same as the area of ​​the third color sub-pixel 13; for example, as Figure 19As shown, the area of ​​the second color sub-pixel 12 is larger than the area of ​​the first color sub-pixel 11, and the areas of the second color sub-pixel 12 and the third color sub-pixel 13 are the same.
