Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of display, and particularly relates to a display panel and a display device. BACKGROUND

[0002] The Color Filter on Encapsulation (COE) technology, also known as the polarizer-free technology, generates an extremely thin high-transmission and low-reflection film (i.e., a color filter) outside the encapsulation layer to correspond to the sub-pixels, and forms a black matrix in the gap between the sub-pixels, which can effectively absorb light, thereby effectively improving the display transmittance while reducing the reflection of ambient light.

[0075] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure.

[0076] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood as the common meanings thereof by the persons with ordinary skills in the art to which the present disclosure belongs. The terms “first”, “second” and similar terms used in the present disclosure do not represent any order, number or importance, but are only used to distinguish different constituent parts.

[0077] Figure 1 A structural schematic diagram of the display panel provided by the embodiment of the present disclosure is shown in FIG. 1, Figure 2a A schematic diagram of the pixel opening and the black matrix opening under Example 1 provided by the embodiment of the present disclosure is shown in FIG. 2, Figure 2b A schematic diagram of the pixel opening and the black matrix opening under Example 2 provided by the embodiment of the present disclosure is shown in FIG. 3.

[0078] Specifically, as Figure 1As shown in Figure 2, the display panel includes a substrate 1, a pixel defining layer PDL and a plurality of sub-pixels 2 disposed on the substrate 1, and a black matrix layer BM disposed on the side of the plurality of sub-pixels 2 facing away from the substrate 1 and a color filter CF disposed corresponding to the sub-pixels 2. The pixel defining layer PDL includes a plurality of pixel openings V1, which define the sub-pixels 2, that is, the pixel openings V1 correspond to the light-emitting areas of the sub-pixels 2. The black matrix layer BM has a plurality of black matrix openings V2, which define the color filter CF, that is, the black matrix openings V2 correspond to the filtering areas of the color filter CF. The color filter CF is used to filter the light emitted by the sub-pixels 2. The black matrix layer BM can absorb both the light emitted by the sub-pixels 2 and the incident light from the external environment. For example, the black matrix layer BM can be a film structure composed of a black matrix (e.g., using black resin as the main material). In this case, the black matrix openings V2 are holes in the entire black matrix material, and the black matrix layer BM is formed at the same time as the holes are made in the entire black matrix material. Alternatively, the black matrix layer BM can also be a light-absorbing structure formed by stacking multiple color filters CF, that is, removing the black matrix and achieving light absorption through a multi-layer color filter stacking scheme. In this case, the black matrix opening V2 is the area between multiple color filters CF (e.g., a stack of red filter CF_R, green light-emitting device CF_G, and blue filter CF_B), used to define a single layer of color filter CF.

[0079] For example, the sub-pixel 2 disclosed herein includes a light-emitting device and a pixel driving circuit for driving the light-emitting device. The light-emitting device may be an OLED light-emitting device. The pixel opening V1, used to define the sub-pixel 2, defines the light-emitting layer EL in the OLED light-emitting device. In addition to the light-emitting layer EL, the OLED light-emitting device also includes at least an anode 01 and a cathode 02 disposed on two opposite sides of the light-emitting layer EL in the thickness direction. For example, the anode 01 is disposed on the side of the light-emitting layer EL closer to the substrate 1, and the cathode 02 is disposed on the side of the light-emitting layer EL away from the substrate 1.

[0080] like Figure 2a and Figure 2b As shown, the orthographic projection of pixel opening V1 onto substrate 1 is a first contour pattern 31, and the orthographic projection of black matrix opening V2 onto substrate 1 is a second contour pattern 32. Exemplarily, the geometric center of the first contour pattern 31 and the geometric center of the second contour pattern 32 are directly opposite each other; for example, their orthographic projections onto substrate 1 coincide. Of course, this is merely an example, and in this disclosure, the orthographic projections of the geometric centers of the first contour pattern 31 and the second contour pattern 32 onto substrate 1 may not coincide.

[0081] At least one of the first profile pattern 31 and the second profile pattern 32 has different curvatures at different points. For example, the first profile pattern 31 has different curvatures at different points, and thus the first profile pattern 31 is a non-circular pattern. For example, the second profile pattern 32 has different curvatures at different points, and thus the second profile pattern 32 is a non-circular pattern.

[0082] In the embodiments of the present disclosure, at least one of the first profile pattern 31 and the second profile pattern 32 is a non-circular pattern.

[0083] Continuing as shown in Figure 2a and Figure 2b , the first profile pattern 31 includes a plurality of first splicing segments 311 connected in sequence; for any two adjacent first splicing segments 311, at least one of them has at least one point with different curvature from at least one point of the other. Thus, at least one of the plurality of first splicing segments 311 is a non-circular arc segment, that is, at least one of the plurality of first splicing segments 311 has a point with different curvature. For example, as shown in Figure 3 , the first profile pattern 31 includes a semicircular arc 401 and a semieliptical arc 501, which are spliced and tangent at the intersection point.

[0084] Alternatively, continuing as shown in Figure 2a and Figure 2b , the second profile pattern 32 includes a plurality of second splicing segments 321 connected in sequence; for any two adjacent second splicing segments 321, at least one of them has at least one point with different curvature from at least one point of the other. Thus, at least one of the plurality of second splicing segments 321 is a non-circular arc segment, that is, at least one of the plurality of second splicing segments 321 has a point with different curvature. For example, as shown in Figure 4 , the second profile pattern 32 includes two circular arcs 402 and 403 and two elliptical arcs 502 and 503, and the circular arcs and the elliptical arcs are arranged alternately and tangent at the intersection point.

[0085] The circular arc mentioned in the present disclosure refers to a certain arc length on a circle with the same curvature, and the specific radian number corresponding to the arc length is not limited and can be any radian number (excluding 0) in 0-2π. For example, the radian number corresponding to the semicircular arc 401 is π, the radian number corresponding to the whole circle is 2π, and the radian number corresponding to the quarter circular arc is π / 2. The elliptical arc mentioned in the present disclosure refers to a certain arc length on an ellipse, and the length of the arc length is also not limited, for example, it can be a semieliptical arc 501, etc., wherein the semieliptical arc 501 can be a semieliptical arc 501 with the two end points of the major axis as the end points, or it can also be a semieliptical arc 501 with the two end points of the minor axis as the end points.

[0086] The embodiments disclosed herein employ unique pattern designs, such as circular arcing and / or elliptical arcing of the first contour pattern 31 of the pixel opening V1 and the second contour pattern 32 of the black matrix opening V2, and splicing the two together, which can improve diffraction phenomena.

[0087] In some embodiments, the multiple first splicing segments 311 include multiple arc segments, or at least one arc segment and a straight line segment; the multiple second splicing segments 321 include multiple arc segments, or at least one arc segment and a straight line segment; the arc segments are circular arcs or elliptical arcs.

[0088] Optionally, the multiple first splicing segments 311 can be a combination of at least one circular arc and at least one elliptical arc. Alternatively, the multiple first splicing segments 311 can be a combination of at least one circular arc and at least one straight line segment. Or, the multiple first splicing segments 311 can be a combination of at least one circular arc, at least one elliptical arc, and at least one straight line segment. Or, the multiple first splicing segments 311 can be a combination of multiple circular arcs with different curvatures. Or, the multiple first splicing segments 311 can be a combination of multiple elliptical arcs.

[0089] Optionally, the multiple second splicing segments 321 can be a combination of at least one circular arc and at least one elliptical arc. Alternatively, the multiple second splicing segments 321 can be a combination of at least one circular arc and at least one straight line segment. Or, the multiple second splicing segments 321 can be a combination of at least one circular arc, at least one elliptical arc, and at least one straight line segment. Or, the multiple second splicing segments 321 can be a combination of multiple circular arcs with different curvatures. Or, the multiple second splicing segments 321 can be a combination of multiple elliptical arcs.

[0090] Figure 3 This is a schematic diagram of a pixel opening or black matrix opening under a patterned design, provided as an embodiment of the present disclosure. In an optional implementation, for the first contour pattern 31 or the second contour pattern 32, such as Figure 3 As shown, the multiple arc segments are divided into two segments, one being a semicircular arc 401 and the other a semielliptical arc 501. The semicircular arc 401 and the semielliptical arc 501 are tangent at their intersection point. Here, the diameter of the first circle 41 after the semicircular arc 401 is restored is equal to the major axis of the first ellipse 51 after the semielliptical arc 501 is restored. The first ellipse 51 is inscribed in the first circle 41, and the point of tangency is the endpoint of the major axis of the first ellipse 51.

[0091] In this embodiment, such as Figure 3 The outline pattern shown can be applied to both pixel opening V1 and black matrix opening V2.

[0092] Figure 4Another schematic diagram of a pixel opening or black matrix opening under a pattern design provided by an embodiment of the present disclosure. In another optional implementation, for the first contour pattern 31 or the second contour pattern 32, as shown in Figure 4 , the multi-segment arc segments are four segments, which are the first segment 402, the second segment 502, the third segment 403 and the fourth segment 503 connected in sequence. The first segment 402 and the third segment 403 are the same, and are both circular arcs. The second segment 502 and the fourth segment 503 are the same, and are both elliptical arcs. Here, "the same" means that the shapes and sizes of the arc segments are the same, but the splicing positions are different. For example, the first segment 402 and the third segment 403 are arranged opposite along the length direction (i.e. the Y direction) of the contour pattern, and the second segment 502 and the fourth segment 503 are arranged opposite along the width direction (i.e. the X direction) of the contour pattern. The two ends of the first segment 402 are respectively the intersection points of the second segment 502 and the fourth segment 503, which are the tangent points of the circular arc and the elliptical arc. The two ends of the third segment 403 are respectively the intersection points of the second segment 502 and the fourth segment 503, which are the tangent points of the circular arc and the elliptical arc. Here, the diameter of the second circle 42 after reduction of the circular arc is equal to the half major axis size of the second ellipse 52 after reduction of the elliptical arc. The second circle 42 is inscribed in the second ellipse 52, and the tangent points of the two are located on the elliptical arc between 3a / 4 and a / 2, where a represents the size of the half major axis of the second ellipse 52. The center of the second circle 42 is located at the a / 4 position of the half major axis. The second circle 42 is also tangent to the reference line perpendicular to the major axis and passing through the 3a / 4 position point of the half major axis. The closed pattern formed by splicing the first segment 402, the second segment 502, the third segment 403 and the fourth segment 503 is an axisymmetric pattern, and the topography is similar to a "capsule" shape.

[0093] In the present embodiment, as shown in Figure 4 , the contour pattern can be applied to the pixel opening V1 and the black matrix opening V2.

[0094] Optionally, the shapes of the first contour pattern 31 and the second contour pattern 32 are different. For example, as shown in Figure 2a and Figure 2b , the first contour pattern 31 adopts the splicing pattern of the half circular arc 401 and the half elliptical arc 501 as shown in Figure 3 . The second contour pattern 32 adopts the "capsule" pattern as shown in Figure 4 . Optionally, the second contour pattern 32 completely wraps the first contour pattern 31, the centers of the first contour pattern 31 and the second contour pattern 32 coincide, and the first contour pattern 31 can rotate at any angle within the second contour pattern 32. Specifically, it can be set on the premise of meeting the maximum aperture ratio. For example, as shown in Figure 2aAs shown, the major axis of the first contour pattern 31 coincides with the major axis of the second contour pattern 32; and / or, the minor axis of the first contour pattern 31 coincides with the minor axis of the second contour pattern 32. Alternatively, the major axis of the first contour pattern 31 and the minor axis of the second contour pattern 32 are perpendicular to each other. For example, as... Figure 2b As shown, the major axis of the first contour pattern 31 coincides with the minor axis of the second contour pattern 32; and / or, the minor axis of the first contour pattern 31 coincides with the major axis of the second contour pattern 32. Alternatively, the major axis of the first contour pattern 31 and the major axis of the second contour pattern 32 are perpendicular to each other.

[0095] For example, such as Figure 2a , Figure 3 and Figure 4 As shown, the extension direction of the line connecting the intersection of the semicircular arc 401 and the semielliptical arc 501 in the first contour pattern 31 is the same as the extension direction of the line connecting the center of the first segment 402 and the center of the third segment 403 in the second contour pattern 32. For example, as shown... Figure 2b , Figure 3 and Figure 4 As shown, the extension direction of the line connecting the intersection of the semicircular arc 401 and the semielliptical arc 501 in the first contour pattern 31 is perpendicular to the extension direction of the line connecting the center of the first segment 402 and the center of the third segment 403 in the second contour pattern 32.

[0096] For example, such as Figure 5 As shown, the first contour pattern 31 adopts the following... Figure 4 The "capsule" pattern shown, the second outline pattern 32 adopts the following... Figure 3 The pattern shown is a combination of semicircular arc 401 and semielliptical arc 501.

[0097] Optionally, the first contour pattern 31 and the second contour pattern 32 have the same shape. For example, as shown... Figure 6 As shown, both the first contour pattern 31 and the second contour pattern 32 adopt the following... Figure 4 The "capsule" pattern shown. For example, as... Figure 7 As shown, both the first contour pattern 31 and the second contour pattern 32 adopt the following... Figure 3 The pattern shown is a combination of semicircular arc 401 and semielliptical arc 501.

[0098] In some embodiments, the first outline pattern 31 is circular or elliptical; the second outline pattern 32 is circular or elliptical.

[0099] Optionally, the first outline pattern 31 is circular, and the shapes of the first outline pattern 31 and the second outline pattern 32 are different. For example, as shown... Figure 8 As shown, the first outline pattern 31 can be a circular pattern, and the second outline pattern 32 can be as follows: Figure 4The "capsule" pattern shown. For example, as... Figure 9 As shown, the first outline pattern 31 can be a circular pattern, and the second outline pattern 32 can be as follows: Figure 3 The pattern shown is a combination of semicircular arc 401 and semielliptical arc 501.

[0100] Optionally, the second contour pattern 32 is elliptical, and the shapes of the first contour pattern 31 and the second contour pattern 32 are different. For example, as shown... Figure 10 As shown, the first contour pattern 31 adopts the following... Figure 4 The "capsule" pattern shown has a second outline pattern 32 that is an elliptical shape. For example, as... Figure 11 As shown, the first contour pattern 31 adopts the following... Figure 3 The pattern shown is a combination of semicircular arc 401 and semielliptical arc 501, and the second outline pattern 32 adopts an elliptical pattern.

[0101] Optionally, such as Figure 12 As shown, the first outline pattern 31 can be an elliptical pattern, and the second outline pattern 32 can be as follows: Figure 4 The "capsule" pattern shown.

[0102] Optionally, such as Figure 13 As shown, the first contour pattern 31 can be adopted as follows: Figure 4 The "capsule" pattern shown, the second outline pattern 32 can be a circular pattern.

[0103] Figure 14 This is a schematic diagram of a pixel opening or black matrix opening under another patterned design provided in an embodiment of this disclosure. In another optional implementation, for the first contour pattern 31 or the second contour pattern 32, such as Figure 14 As shown, there are four arc segments, which are the intersecting arc segments of the third ellipse 53 and the fourth ellipse 54. Here, the third ellipse 53 and the fourth ellipse 54 can overlap at any angle.

[0104] Optionally, such as Figure 14 As shown, the centers of the third ellipse 53 and the fourth ellipse 54 coincide, and their major axes are perpendicular to each other. The pattern retained after their intersection is the first contour pattern 31 or the second contour pattern 32. The four elliptical arcs formed are the first intersecting sub-segment 504, the second intersecting sub-segment 505, the third intersecting sub-segment 506, and the fourth intersecting sub-segment 507.

[0105] Optionally, such as Figure 14As shown, the third ellipse 53 and the fourth ellipse 54 are identical, meaning they have the same dimensions, such as their major and minor axes. When the third ellipse 53 and the fourth ellipse 54 intersect, their centers intersect, and their major axes are perpendicular to each other, forming a centrally symmetrical pattern, similar to a "round square". Furthermore, rounded corners are formed between adjacent arc segments to ensure a smooth transition and further improve diffraction.

[0106] Optionally, the eccentricity of the third ellipse 53 and the fourth ellipse 54 is between 0 and 0.75, excluding 0. For example, the eccentricity is 0.65.

[0107] In this embodiment, such as Figure 14 The "circle-square" pattern shown can be applied to both pixel opening V1 and black matrix opening V2.

[0108] Optionally, such as Figure 15 As shown, the first contour pattern 31 adopts the following... Figure 14 The "round square" pattern shown has an elliptical pattern for the second outline pattern 32.

[0109] Optionally, such as Figure 16 As shown, the first outline pattern 31 can be a circular pattern, and the second outline pattern 32 can be as follows: Figure 14 The "round square" pattern shown.

[0110] Optionally, such as Figure 17 As shown, the first contour pattern 31 can be adopted as follows: Figure 3 The splicing pattern of the semicircular arc 401 and the semielliptical arc 501 shown, the second contour pattern 32 can be adopted as follows: Figure 14 The "round square" pattern shown.

[0111] Figures 18a-18c These are schematic diagrams of pixel openings or black matrix openings under another patterned design provided in this disclosure embodiment. In another optional embodiment, for the first contour pattern 31 or the second contour pattern 32, such as Figures 18a-18c As shown, the arc segment is one segment, and it is an elliptical arc 508; the straight line segment 601 is one segment; the extension direction of the straight line segment 601 is the same as the extension direction of the minor axis of the fifth ellipse 55 after the restoration of the elliptical arc 508, and the straight line segment 601 is located between the center O of the fifth ellipse 55 and the vertex A of the semi-major axis.

[0112] For example, such as Figure 18a As shown, line segment 601 is located at position a / 2 of the semi-major axis of the fifth ellipse 55. For example, as... Figure 18b As shown, line segment 601 is located at position a / 4 of the semi-major axis of the fifth ellipse 55. For example, as... Figure 18cAs shown, line segment 601 is located at the center O of the fifth ellipse 55.

[0113] Optionally, such as Figures 18a-18c The outline pattern shown resembles a "semi-ellipse" shape. Specifically, it can be the pattern retained after cutting off the elliptical arcs corresponding to a / 4 to a along the minor axis of the fifth ellipse 55.

[0114] In this embodiment, such as Figures 18a-18c The outline pattern shown can be applied to both pixel opening V1 and black matrix opening V2.

[0115] Optionally, such as Figures 19a-19e As shown, the first contour pattern 31 can be adopted as follows: Figure 3 The splicing pattern or circular pattern of the semicircular arc 401 and the semielliptical arc 501 shown, such as Figure 19a The second contour pattern 32 shown can be adopted as follows: Figure 18a The pattern shown is a semi-elliptical shape. (Example:) Figure 19b and Figure 19c The second contour pattern 32 shown all adopt the following... Figure 18b The pattern shown is a semi-elliptical shape; among which, as shown in the figure... Figure 19b The first outline pattern 31 shown and Figure 19c The relative positions of the first contour pattern 31 with respect to the second contour pattern 32 are different. For example... Figure 19b The first contour pattern 31 shown is located within the second contour pattern 32 and does not intersect with the second contour pattern 32; Figure 19c The first contour pattern 31 shown is located within the second contour pattern 32, but intersects with it; that is, the first contour pattern 31 is inscribed within the second contour pattern 32. For example... Figure 19d The second outline pattern 32 shown is a semi-elliptical pattern, but its size is similar to that shown in the image. Figure 19b and Figure 19c The second contour pattern 32 shown is of a different size, and the relative position of the first contour pattern 31 with respect to the second contour pattern 32 is different. For example Figure 19d The shortest distance of the straight line segment 601 from the first contour pattern 31 to the second contour pattern 32 shown is less than Figure 19b or Figure 19c The shortest distance of the straight line segment 601 from the first contour pattern 31 to the second contour pattern 32 shown. For example... Figure 19e The second contour pattern 32 shown can be adopted as follows: Figure 18cThe pattern shown is a semi-elliptical shape. The first contour pattern 31 may be located inside the second contour pattern 32 and may not intersect with the second contour pattern 32; or the first contour pattern 31 may be internally tangent to the second contour pattern 32, which may be an elliptical arc 508 internally tangent to the second contour pattern 32, or a straight line segment 601 internally tangent to the second contour pattern 32.

[0116] Of course, the above are only some examples. The first contour pattern 31 in this disclosure can be rotated at any angle within the second contour pattern 32, specifically, it can be set to meet the premise of the maximum opening ratio.

[0117] Optionally, such as Figures 20a-20c As shown, the first contour pattern 31 can be adopted as follows: Figures 18a-18c The "semi-elliptical" pattern shown, the second outline pattern 32 can be adopted as follows: Figure 3 The pattern shown is a combination of semicircular arc 401 and semielliptical arc 501, or a circular pattern.

[0118] Optionally, the first outline pattern 31 can be adopted as follows: Figure 3 The splicing pattern of the semicircular arc 401 and the semielliptical arc 501 shown, or the circular pattern, the second outline pattern 32 can be a semicircular pattern.

[0119] Figures 21a-21f These are schematic diagrams of pixel openings or black matrix openings under another patterned design provided in this disclosure embodiment. In another optional embodiment, for the first contour pattern 31 or the second contour pattern 32, such as Figures 21a-21f As shown, the multiple arc segments are the combined arc segments of the sixth ellipse 56 and the seventh ellipse 57. "Combined" means that the sixth ellipse 56 and the seventh ellipse 57 are connected as one. Therefore, the combined arc segment is the pattern formed by the outer contours of the sixth ellipse 56 and the seventh ellipse 57 after removing the intersecting contours. For example, it could be two elliptical arcs, such as... Figure 21a and Figure 21b The first joint sub-segment 509 and the second joint sub-segment 5010 are shown. For example, it could be four elliptical arcs, such as... Figure 21c The third joint sub-segment 5011, the fourth joint sub-segment 5012, the fifth joint sub-segment 5013, and the sixth joint sub-segment 5014 are shown.

[0120] Optionally, the major axis of the sixth ellipse 56 is greater than the major axis of the seventh ellipse 57; the minor axis of the sixth ellipse 56 is less than the minor axis of the seventh ellipse 57.

[0121] In this embodiment, the sixth ellipse 56 and the seventh ellipse 57 can be joined at any angle and position, provided that they overlap. Figures 21a-21f These are just examples of some of the joint methods; they will not be listed one by one here.

[0122] Optionally, as shown in FIG. 21, the sixth ellipse 56 and the seventh ellipse 57 are the same, where "the same" means the same size, such as the major axis and the minor axis, etc. When the sixth ellipse 56 and the seventh ellipse 57 are combined, the centers of the sixth ellipse 56 and the seventh ellipse 57 do not intersect, but the major axes of the sixth ellipse 56 and the seventh ellipse 57 are perpendicular to each other. Further, the adjacent two arc segments form a rounded corner to smooth the transition, further improving the diffraction. Figure 21a and Figure 21b As shown in FIG. 20, the sixth ellipse 56 and the seventh ellipse 57 intersect each other, and the sixth ellipse 56 and the seventh ellipse 57 are tangent at a point. Specifically, as shown in FIG. 20, the sixth ellipse 56 and the seventh ellipse 57 have only one tangent point, and it is a vertex of the major axis of each. The sixth ellipse 56 and the seventh ellipse 57 have two intersection points A and B in addition to the tangent point, which are symmetric about the major axis of the sixth ellipse 56 (or the seventh ellipse 57). For example, both intersection points A and B are located on the half-ellipse arc of the sixth ellipse 56 (or the seventh ellipse 57) that is divided by the minor axis and away from the tangent point. As shown in FIG. 20, the sixth ellipse 56 and the seventh ellipse 57 have only one tangent point, which is a vertex of the minor axis of each. The sixth ellipse 56 and the seventh ellipse 57 have two intersection points C and D in addition to the tangent point, which are symmetric about the minor axis of the sixth ellipse 56 (or the seventh ellipse 57). For example, both intersection points C and D are located on the half-ellipse arc of the sixth ellipse 56 (or the seventh ellipse 57) that is divided by the major axis and away from the tangent point. Optionally, as shown in FIG. 20, the sixth ellipse 56 and the seventh ellipse 57 have only one tangent point, which can be a tangent point E at a random position, and have two intersection points F and G. For example, the major axis of the sixth ellipse 56 and the major axis of the seventh ellipse 57 can be perpendicular. Figure 21a Figure 21b Figure 21c

[0123] Optionally, as shown in FIG. 21, the sixth ellipse 56 and the seventh ellipse 57 are the same, where "the same" means the same size, such as the major axis and the minor axis, etc. When the sixth ellipse 56 and the seventh ellipse 57 are combined, the centers of the sixth ellipse 56 and the seventh ellipse 57 do not intersect, but the major axes of the sixth ellipse 56 and the seventh ellipse 57 are perpendicular to each other. Further, the adjacent two arc segments form a rounded corner to smooth the transition, further improving the diffraction. Figure 21d

[0124] Optionally, the sixth ellipse 56 and the seventh ellipse 57 in the present disclosure can be different.

[0125] Optionally, as shown in FIG. 21, the sixth ellipse 56 and the seventh ellipse 57 are the same, where "the same" means the same size, such as the major axis and the minor axis, etc. When the sixth ellipse 56 and the seventh ellipse 57 are combined, the centers of the sixth ellipse 56 and the seventh ellipse 57 do not intersect, but the major axes of the sixth ellipse 56 and the seventh ellipse 57 are perpendicular to each other. Further, the adjacent two arc segments form a rounded corner to smooth the transition, further improving the diffraction. Figure 21e

[0126] Optionally, as shown in FIG. 21, the sixth ellipse 56 and the seventh ellipse 57 are the same, with the difference from FIG. 20 being that the minor axis of the sixth ellipse 56 is shorter and the major axis is longer. Figure 21f Optionally, as shown in FIG. 21, the sixth ellipse 56 and the seventh ellipse 57 are the same, with the difference from FIG. 20 being that the minor axis of the sixth ellipse 56 is shorter and the major axis is longer.​​​​​

[0127] In this embodiment, the "combined" pattern as shown in Figures 21a-21f can be applied to the pixel opening V1 and the black matrix opening V2.

[0128] Optionally, as shown in Figure 22 , the first contour pattern 31 can adopt a "combined" pattern as shown in Figures 21a-21f , here only take the "combined" pattern as shown in Figure 21a as an example, other "combined" patterns are the same, this disclosure will not list one by one. The second contour pattern 32 can adopt a splicing pattern of semicircular arc 401 and semicircular arc 501 as shown in Figure 3 .

[0131] Figure 25 Another schematic diagram of pixel opening or black matrix opening under another patterning design provided by the embodiment of the present disclosure. In another optional embodiment, for the first contour pattern 31 or the second contour pattern 32, as shown in Figure 25 , the multi-segment arc segment is four segments, which are the fifth segment 5015, the sixth segment 5016, the seventh segment 5017 and the eighth segment 5018 connected in order; the fifth segment 5015 and the seventh segment 5017 are the same, and both are elliptical arcs; the sixth segment 5016 and the eighth segment 5018 are the same, and both are elliptical arcs. Here "same" means that the shape and size of the arc segment are the same, but the splicing position is different. Optionally, the fifth segment 5015 elliptical arc is reduced to the eighth ellipse 58, the sixth segment 5016 elliptical arc is reduced to the ninth ellipse 59, the seventh segment 5017 elliptical arc is reduced to the tenth ellipse 510, and the eighth segment 5018 elliptical arc is reduced to the eleventh ellipse 511.

[0132] Optionally, the dimensions of the eighth ellipse 58, the ninth ellipse 59, the tenth ellipse 510, and the eleventh ellipse 511 are all the same. Alternatively, the dimensions of the eighth ellipse 58 and the tenth ellipse 510 are all the same, as are the dimensions of the ninth ellipse 59 and the eleventh ellipse 511. The two ends of the fifth segment 5015 intersect with the sixth segment 5016 and the eighth segment 5018, respectively, which are the tangent points of the elliptical arcs, that is, the tangent points of the eighth ellipse 58 with the ninth ellipse 59 and the eleventh ellipse 511, respectively. The two ends of the seventh segment 5017 intersect with the sixth segment 5016 and the eighth segment 5018, respectively, which are the tangent points of the elliptical arcs, that is, the tangent points of the tenth ellipse 510 with the ninth ellipse 59 and the eleventh ellipse 511, respectively. This ultimately forms a relatively smooth and drum-shaped pattern, which is beneficial for improving diffraction.

[0133] In this embodiment, such as Figure 25 The "drum-shaped" pattern shown can be applied to both pixel opening V1 and black matrix opening V2.

[0134] Optionally, such as Figure 26 As shown, the first contour pattern 31 can be adopted as follows: Figure 3 The splicing pattern of semicircular arc 401 and semielliptical arc 501 shown, or as... Figure 4 The "capsule" pattern shown, the second outline pattern 32 can be adopted as follows: Figure 25 The "drum-shaped" pattern shown.

[0135] Optionally, such as Figure 27 As shown, the first outline pattern 31 can be a circular pattern or an elliptical pattern, and the second outline pattern 32 can be as follows: Figure 25 The "drum-shaped" pattern shown.

[0136] Optionally, such as Figure 28a As shown, the first contour pattern 31 can be adopted as follows: Figure 25 The "drum-shaped" pattern shown, the second outline pattern 32 can be adopted as follows: Figure 3 The pattern shown is a combination of semicircular arc 401 and semielliptical arc 501. Figure 28b As shown, the first contour pattern 31 can be adopted as follows: Figure 25 The "drum-shaped" pattern shown, the second outline pattern 32 can be adopted or as shown in the figure. Figure 4 The "capsule" pattern shown.

[0137] Optionally, such as Figure 28c As shown, the first contour pattern 31 can be adopted as follows: Figure 25 The "drum-shaped" pattern shown can be an elliptical pattern for the second outline pattern 32, and the length direction of the first outline pattern 31 is the same as the long axis direction of the second outline pattern 32.

[0138] Optionally, such asFigure 28d As shown, the first contour pattern 31 can be adopted as follows: Figure 25 The "drum-shaped" pattern shown can have an elliptical second outline pattern 32, where the length direction of the first outline pattern 31 is the same as the minor axis direction of the second outline pattern 32. For example, the first outline pattern 31 is inscribed within the second outline pattern 32. For instance, the midpoint of two oppositely arranged elliptical arcs in the first outline pattern 31 is tangent to the endpoint of the minor axis of the second outline pattern 32.

[0139] Optionally, such as Figure 29a and Figure 29b As shown, the first contour pattern 31 can be adopted as follows: Figure 25 The "drum-shaped" pattern shown can have a circular outline pattern 32. For example, Figure 29a As shown, the second contour pattern 32 surrounds the first contour pattern 31 and does not intersect with the first contour pattern 31. Figure 29b As shown, the first contour pattern 31 is inscribed in the second contour pattern 32.

[0140] In addition, the embodiments provided above in this disclosure are as follows: Figure 3 The splicing pattern of semicircular arc 401 and semielliptical arc 501 shown is as follows: Figure 4 The "capsule" pattern shown, such as Figure 14 The "round square" pattern shown, such as Figures 18a-18c The "semi-elliptical" pattern shown, such as Figures 21a-21f The "union" pattern shown, such as Figure 25 Two of the "drum-shaped" patterns shown can be arbitrarily selected as the first outline pattern 31 and the second outline pattern 32. Alternatively, as... Figure 3 The splicing pattern of semicircular arc 401 and semielliptical arc 501 shown is as follows: Figure 4 The "capsule" pattern shown, such as Figure 14 The "round square" pattern shown, such as Figures 18a-18c The "semi-elliptical" pattern shown, such as Figures 21a-21f The "union" pattern shown, such as Figure 25 The "drum-shaped" pattern shown can be any one of the circular patterns, used as the first outline pattern 31 and the second outline pattern 32. Alternatively, as... Figure 3 The splicing pattern of semicircular arc 401 and semielliptical arc 501 shown is as follows: Figure 4 The "capsule" pattern shown, such as Figure 14 The "round square" pattern shown in Figure 18~ Figure 18c The "semi-elliptical" pattern shown, such as Figures 21a-21f The "union" pattern shown, such as Figure 25 One of the "drum-shaped" patterns shown can be chosen from the elliptical pattern as the first outline pattern 31 and the second outline pattern 32.

[0141] Exemplarily, possible implementations of the first profile pattern 31 and the second profile pattern 32 can be shown in Table 1 as follows.

[0144] In some embodiments, for the first profile pattern 31 and the second profile pattern 32 corresponding to any pair of sub-pixels 2, the combined pattern can be rotated at any angle.

[0145] It should be noted that the above patterning design in the embodiments of the present disclosure is applicable to various sub-pixel arrangement modes such as real RGB and Pentile RGB, and the following will be described by taking Pentile RGB as an example. The real RGB sub-pixel arrangement mode is also applicable, and thus will not be described again.

[0146] In some embodiments, the first profile pattern 31 or the second profile pattern 32 corresponding to adjacent sub-pixels 2 has a certain included angle between the respective length directions. As shown in Figure 30 and Figure 31 The so-called "length direction" refers to the major axis direction of the elliptical pattern.

[0147] In one possible implementation, the display panel includes a plurality of groups of pixel units, each group of pixel units including a plurality of pixel units, for example, a single group of pixel units including 8x8 pixel units or 4x4 pixel units. Each pixel unit includes a plurality of sub-pixels of different colors; for example, the pixel unit includes a red sub-pixel r, a green sub-pixel g, and a blue sub-pixel b. As shown in Figure 30 For at least one of the plurality of groups of pixel units, a plurality of groups of sub-pixels 20 are divided according to the diagonal direction thereof, each group of sub-pixels 20 being arranged side by side with a plurality of sub-pixels 2 in the diagonal direction; for any group of sub-pixels 20, the rotation angle difference of any two adjacent sub-pixels 2 in the diagonal direction is the same; for two adjacent groups of sub-pixels 20, the rotation angle difference of any two adjacent sub-pixels 2 in the diagonal direction of one group is different from the rotation angle difference of any two adjacent sub-pixels 2 in the diagonal direction of the other group. Here, the rotation angle difference refers to the absolute value of the difference between the rotation angles of the two adjacent sub-pixels 2, which is a positive number.

[0148] Optionally, as shown in Figure 30As shown, taking n x n pixel units as an example, the pixel unit group is divided into a plurality of sub-pixel groups 20 according to the diagonal direction of the pixel unit group, the rotation angle of two adjacent sub-pixels 2 in each sub-pixel group 20 in the diagonal direction is different by 180 / n, that is, the rotation step, wherein n represents the number of sub-pixels 2 in the sub-pixel group 20. The rotation step of any two sub-pixels 2 in the same sub-pixel group 20 is equal, and the rotation angle of one of the diagonal lines increases by the rotation step in turn. The directions of the diagonal lines referred to by adjacent two sub-pixel groups 20 are opposite, which means that the directions of the rotation steps increasing in turn are opposite; alternatively, it can be understood that the rotation angles of two adjacent sub-pixels 2 in adjacent two sub-pixel groups 20 are opposite. The positions of the sub-pixels 2 starting to rotate in adjacent two sub-pixel groups 20 are located at the end away from the arrow. The rotation steps corresponding to different sub-pixel groups 20 are different, for example, the rotation steps corresponding to adjacent two sub-pixel groups 20 are different by 1 / 2β, that is, the rotation step of the latter sub-pixel group 20 is less than the rotation step of the former sub-pixel group 20 by 1 / 2β, and β represents the rotation step of the former sub-pixel group 20. The "former sub-pixel group 20" and "latter sub-pixel group 20" refer to any two adjacent sub-pixel groups 20, and the "former sub-pixel group 20" is closer to the center of the pixel unit group than the "latter sub-pixel group 20".

[0149] In another possible implementation manner, as shown in Figure 31 for at least one of the plurality of pixel unit groups, the pixel unit group is divided into a plurality of sub-pixel groups 20 nested in turn according to the surrounding direction, and each sub-pixel group 20 is uniformly provided with a plurality of sub-pixels 2 in the surrounding direction; for any sub-pixel group 20, the rotation angle difference of any two adjacent sub-pixels 2 in the surrounding direction is the same; for adjacent two sub-pixel groups 20, the rotation angle difference of any two adjacent sub-pixels 2 in the surrounding direction of one is different from the rotation angle difference of any two adjacent sub-pixels 2 in the surrounding direction of the other.

[0150] Optionally, as shown in Figure 31As shown, the pixel unit includes a red sub-pixel 2, a green sub-pixel 2, and a blue sub-pixel 2. Taking an n x n pixel unit as an example, the pixel unit is divided into a plurality of sub-pixel groups 20 arranged in sequence. The rotation angle of any two adjacent sub-pixels 2 in each sub-pixel group 20 around the center of the pixel unit group differs by 180 / n, that is, the rotation step, where n represents the number of sub-pixels 2 in the sub-pixel group 20. The rotation step of any two sub-pixels 2 in the same sub-pixel group 20 is equal, and the rotation angle around the center of the pixel unit group increases in sequence according to the rotation step. The rotation steps of different sub-pixel groups 20 are different, and the directions around the center of the pixel unit group referred to by adjacent two sub-pixel groups 20 are the same. The rotation steps corresponding to adjacent two sub-pixel groups 20 differ by 1 / 2β, that is, the rotation step of the latter sub-pixel group 20 is 1 / 2β less than the rotation step of the former sub-pixel group 20, and β represents the rotation step of the former sub-pixel group 20. The “former sub-pixel group 20” and “latter sub-pixel group 20” refer to any two adjacent sub-pixel groups 20, and the “former sub-pixel group 20” is closer to the center of the pixel unit group than the “latter sub-pixel group 20”.

[0151] For the first contour pattern 31 and the second contour pattern 32 corresponding to any color of sub-pixel 2, the combined pattern can be arranged according to the rules shown in the above Figure 30 or Figure 31 , that is, a single sub-pixel 2 can be arranged in the random manner shown in the above Figure 30 or Figure 31 . Alternatively, only sub-pixels 2 of one color can be designed according to the above embodiments, and sub-pixels 2 of other colors are not processed. Alternatively, sub-pixels 2 of any two colors of red sub-pixels, green sub-pixels, and blue sub-pixels can be designed according to the above embodiments, and sub-pixels 2 of the remaining color are not processed.

[0152] In some embodiments, the maximum distance between the first contour pattern 31 and the second contour pattern 32 is between 0 and 10 μm. Alternatively, the distance between the first contour pattern 31 and the second contour pattern 32 is between 0 and 5 μm.

[0153] For the “capsule” pattern shown in the above Figure 4 , rotation is performed according to a 20° rotation step, and diffraction simulation test is performed, and the simulation result is shown in the above Figure 32 . For the “circle-square” pattern shown in the above Figure 14 , rotation is performed according to a 20° rotation step, and diffraction simulation test is performed, and the simulation result is shown in the above Figure 33 . For the elliptical pattern, rotation is performed according to a 10° rotation step, and diffraction simulation test is performed, and the simulation result is shown in the above Figure 34As shown. Diffraction simulation tests were performed on the circular pattern, and the simulation results are as follows. Figure 35 As shown in the simulation results, compared to the diffraction effect of the circular pattern, the "capsule" pattern, after pixel rotation, has fewer diffraction rings, indicating an improved diffraction effect. Compared to the circular pattern, the "round-square" pattern, after pixel rotation, has a fainter outer diffraction ring, indicating an improved diffraction effect. Compared to the circular pattern, the "elliptical" pattern, after pixel rotation, has fewer diffraction rings, indicating an improved diffraction effect.

[0154] In some embodiments, such as Figure 1 As shown, the pixel driving circuit includes at least a driving transistor TFT. A planarization layer PDL is disposed between the pixel driving circuit and the light-emitting device. The light-emitting device includes a red light-emitting device R, a green light-emitting device G, and a blue light-emitting device (not shown in the figure). The color filter CF includes a red filter CF_R corresponding to the red light-emitting device R, a green filter CF_G corresponding to the green light-emitting device G, and a blue filter (not shown in the figure) corresponding to the blue light-emitting device. An encapsulation layer 6 is disposed between the color filter CF and the light-emitting device. The encapsulation layer 6 can be a multilayer structure, such as a stacked structure of an inorganic encapsulation layer, an organic encapsulation layer, and an inorganic encapsulation layer. A protective layer 7 is disposed on the side of the color filter CF facing away from the substrate 1.
