DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] The terms "first", "second" and "first" in this application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one of these features. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative positional relationship, movement, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0034] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, that the embodiments described herein may be combined with other embodiments.

[0035] Currently, the conventional production method for organic light-emitting diodes (OLEDs) is to use a metal mask (FMM) to define the material vapor deposition area, and then complete it through the production of a light extraction layer and TFE packaging. Due to the perfect self-luminous properties of organic light-emitting diodes (OLEDs), they are widely favored in the display panel field.

[0036] At the same time, with the development of technology, a technology has emerged that uses photolithography technology to produce light-emitting units of organic light-emitting diodes. The pixels are separated by a conductive structure OH (Over Hang), and an insulating hanging structure is made on the OH. The significant feature is that the PDL (Pixel Definition Layer) GAP (spacing) between pixels is effectively reduced, which can meet the needs of product design or display of PPI (pixel density) or high pixel opening.

[0037] Currently, the most commonly used pixel structure in display products is the diamond structure, or a diamond-like structure, which provides relatively ideal display effects. However, display panels fabricated with the diamond pixel structure are prone to color fringing and jagged edges, which affect the display quality.

[0038] In order to solve the above problems, the present application provides a pixel structure.

[0039] See also Figures 1 to 3 , Figure 1 is a schematic diagram of the pixel structure provided by this application; Figure 2 is a schematic structural diagram of a pixel area provided in the first embodiment of the present application; Figure 3 yes Figure 2 A schematic structural diagram of four pixel units in the first embodiment is provided.

[0040] The pixel structure 100 provided in the present application includes: a plurality of repeating units 10 arranged in an array along a row direction X and a column direction Y; wherein each repeating unit 10 includes two first sub-pixels 111, two second sub-pixels 112, and four third sub-pixels 113;

[0041] In each repeating unit 10, two first sub-pixels 111 and two second sub-pixels 112 are arranged around the geometric center point O of the repeating unit 10, that is, the two first sub-pixels 111 and the two second sub-pixels 112 are arranged along the geometric center point O, and the outer contours of each first sub-pixel 111 and each second sub-pixel 112 pass through the geometric center point O, and the geometric center point O is the common center point of the two first sub-pixels 111 and the two second sub-pixels 112.

[0042] The two first sub-pixels 111 and the two second sub-pixels 112 are alternately arranged along the circumferential direction, where the circumferential direction can be understood as the direction surrounding the geometric center point O of the repeating unit 10. It can be understood that: along the geometric center point O, one first sub-pixel 111, one second sub-pixel 112, another first sub-pixel 111, and another second sub-pixel 112 are arranged in sequence. Moreover, the first sub-pixels 111 and the second sub-pixels 112 adjacent to each other along the circumferential direction at least partially have a common edge (defined as the first common edge D1), which separates the first sub-pixels 111 and the second sub-pixels 112. The four third sub-pixels 113 are arranged around the two first sub-pixels 111 and the two second sub-pixels 112; specifically, the four third sub-pixels 113 are arranged around the two first sub-pixels 111 and the two second sub-pixels 112 along the geometric center point O of the repeating unit 10.

[0043] The colors of the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are all different. In this embodiment, the first sub-pixel 111 is a red sub-pixel (R), the second sub-pixel 112 is a green sub-pixel (G), and the third sub-pixel 113 is a blue sub-pixel (B). The area of ​​the first sub-pixel 111 and the area of ​​the second sub-pixel 112 are both smaller than the area of ​​the third sub-pixel 113. Because the material used to make the third sub-pixel 113 (blue sub-pixel) has a shorter service life than the materials used to make the first and second sub-pixels 111 and 112, the area of ​​the third sub-pixel 113 is maximized to extend the service life of the third sub-pixel 113. The area of ​​the second sub-pixel 112 is greater than or equal to the area of ​​the first sub-pixel 111. Specifically, the design can be based on the service life of the materials used to make the first and second sub-pixels 111 and 112. The present application arranges the sub-pixels within the above-mentioned pixel area 1 and the repeating unit 10 so that each repeating unit 10 has a first sub-pixel 111, a second sub-pixel 112 and a third sub-pixel 113 in the horizontal, vertical and diagonal directions. When the sub-pixels are lit, the displayed colors will be complementary, so that the display panel 300 using this pixel structure 100 will not have the problem of color fringing when displaying, whether in the horizontal, vertical or diagonal directions, thereby improving the display effect.

[0044] In some embodiments, the shape of the repeating unit 10 is a quadrilateral, which is defined as a first quadrilateral 12; the two first sub-pixels 111 are arranged symmetrically along the geometric center point O of the repeating unit 10; the two second sub-pixels 112 are arranged symmetrically along the geometric center point O of the repeating unit 10; and the four third sub-pixels 113 constitute the four corners of the first quadrilateral 12.

[0045] Specifically, the four third sub-pixels 113 are arranged one by one at the four corners of the first quadrilateral 12, and each third sub-pixel 113 has a common edge with the first sub-pixel 111 and the second sub-pixel 112, and the common edge of the third sub-pixel 113 and the first sub-pixel 111 (defined as the second common edge D2), and the common edge of the third sub-pixel 113 and the second sub-pixel 112 (defined as the third common edge D3) are arranged collinearly.

[0046] In some embodiments, the repeating unit 10 is shaped like a quadrilateral, defined as a first quadrilateral 12. The midpoints of the four sides of the first quadrilateral 12 are connected to form a second quadrilateral 13. The outer contour of the pattern formed by the combination of the two first sub-pixels 111 and the two second sub-pixels 112 constitutes the second quadrilateral 13. The four third sub-pixels 113 are disposed in the corner regions of the first quadrilateral 12, excluding the second quadrilateral 13. In other words, the four third sub-pixels 113 are disposed at the four corners of the first quadrilateral 12. Furthermore, the four third sub-pixels 113 are arranged around the geometric center point O of the repeating unit 10, surrounding the two first sub-pixels 111 and the two second sub-pixels 112. It can also be understood that a second common side D2 and a third common side D3 can form a side of the second quadrilateral 13. The four third sub-pixels 113, along with all common sides of the two first sub-pixels 111 and the two second sub-pixels 112, form the four sides of the second quadrilateral 13.

[0047] In some embodiments, as Figure 1 As shown, multiple repeating units 10 are arranged in multiple rows and columns; wherein, in the pixel structure 100, the repeating units 10 in odd rows and even columns have the same structure as the repeating units 10 in even rows and odd columns; the repeating units 10 in odd rows and odd columns have the same structure as the repeating units 10 in even rows and even columns.

[0048] Specifically, along the row direction X, the structures of the odd-numbered repeating units 10 in the same row are identical, the structures of the even-numbered repeating units 10 in the same row are identical, and the structures of the odd-numbered repeating units 10 in the same row are different from the structures of the even-numbered repeating units 10. Along the column direction Y, the structures of the odd-numbered repeating units 10 in the same column are identical, the structures of the even-numbered repeating units 10 in the same column are identical, and the structures of the odd-numbered repeating units 10 in the same column are different from the structures of the even-numbered repeating units 10. For example, the structures of the repeating units 10 in the first row and second column are identical to the structures of the repeating units 10 in the second row and first column, and the structures of the repeating units 10 in the first row and first column are identical to the structures of the repeating units 10 in the second row and second column. The identical structures of the repeating units 10 can be understood as identical shapes, sizes, sub-pixel arrangements within the repeating units 10, sub-pixel areas, etc.

[0049] In other embodiments, Figure 1As shown, pixel structure 100 may include multiple pixel regions 1, each pixel region 1 including four repeating units 10. Four repeating units 10 in two adjacent rows and two adjacent columns form a quadrilateral pixel region 1. It will be appreciated that, given that each repeating unit 10 is a square, the quadrilateral formed by four repeating units 10 in two adjacent rows and two adjacent columns is also a square. Specifically, the four repeating units 10 within the same pixel region 1 can be defined, in sequence, as a first repeating unit 101, a second repeating unit 102, a third repeating unit 103, and a fourth repeating unit 104.

[0050] like Figure 1 As shown, pixel region 1 includes a first diagonal line S1 and a second diagonal line S2. Within each pixel region 1, the first repeating unit 101 and the third repeating unit 103 arranged along the first diagonal line S1 have the same structure; the second repeating unit 102 and the fourth repeating unit 104 arranged along the second diagonal line S2 have the same structure. Similarly, the same structure of the repeating units 10 can be understood as the same shape, size, arrangement of sub-pixels within the repeating unit 10, sub-pixel area, etc.

[0051] In some embodiments, as Figures 2 and 3 As shown, within each repeating unit 10, any two adjacent third sub-pixels 113 along the circumferential direction are arranged axially symmetrically; each repeating unit 10 includes four pixel units 11; the four pixel units 11 within the repeating unit 10 can be respectively defined as a first pixel unit 1101, a second pixel unit 1102, a third pixel unit 1103, and a fourth pixel unit 1104. Each pixel unit includes a first sub-pixel 111, a second sub-pixel 112, and a third sub-pixel 113.

[0052] Along the row direction X, in the first repeating unit 101 and the third repeating unit 103, two adjacent pixel units share a first sub-pixel 111; and in the second repeating unit 102 and the fourth repeating unit 104, two adjacent pixel units share a second sub-pixel 112. For example, along the row direction X, in the first repeating unit 101, the first pixel unit 1101 and the second pixel unit 1102 share one first sub-pixel 111, and the third pixel unit 1103 and the fourth pixel unit 1104 share another first sub-pixel 111. For another example, along the row direction X, in the second repeating unit 102, the first pixel unit 1101 and the second pixel unit 1102 share one second sub-pixel 112, and the third pixel unit 1103 and the fourth pixel unit 1104 share another second sub-pixel 112.

[0053] Along the column direction Y, within the first repeating unit 101 and the third repeating unit 103, two adjacent pixel units share a second sub-pixel 112; and within the second repeating unit 102 and the fourth repeating unit 104, two adjacent pixel units share a first sub-pixel 111. For example, along the column direction Y, within the first repeating unit 101, the first pixel unit 1101 and the third pixel unit 1103 share one second sub-pixel 112, and the second pixel unit 1102 and the fourth pixel unit 1104 share another second sub-pixel 112. For another example, along the column direction Y, within the second repeating unit 102, the first pixel unit 1101 and the third pixel unit 1103 share one first sub-pixel 111, and the second pixel unit 1102 and the fourth pixel unit 1104 share another first sub-pixel 111.

[0054] like Figures 2 to 8 As shown, in the following embodiments provided in the present application, in each repeating unit 10, the first quadrilateral 12 is a square, specifically a square; in the first structure of the first embodiment to the third embodiment, the second quadrilateral 13 is a square; in the second structure of the third embodiment to the fifth embodiment, the second quadrilateral 13 forms a polygon.

[0055] The specific structures and shapes of the first sub-pixel 111 , the second sub-pixel 112 , and the third sub-pixel 113 are described below through specific embodiments.

[0056] First embodiment:

[0057] like Figures 2 and 3 As shown, in this embodiment, the first sub-pixel 111 and the second sub-pixel 112 are both square in shape, and the third sub-pixel 113 is triangular in shape. It can be understood that since the first quadrilateral 12 and the second quadrilateral 13 are both squares, and the areas of the first sub-pixel 111 and the second sub-pixel 112 are equal, the shapes of the first sub-pixel 111 and the second sub-pixel 112 can both be squares. Furthermore, one corner of the third sub-pixel 113 coincides with a corner of the square first quadrilateral 12, and therefore the shape of the third sub-pixel 113 can specifically be an isosceles right triangle.

[0058] like Figures 1 to 3 As shown, the adjacent first sub-pixel 111 and the second sub-pixel 112 both have a common edge (ie, a first common edge D1), and at least a portion of the first common edge D1 is located on the diagonal line of the repeating unit 10; for example, Figure 2As shown in FIG, the first common edges D1 of the two first sub-pixels 111 and the two second sub-pixels 112 are both located on a diagonal line of the repeating unit 10. The areas of the first sub-pixels 111 and the second sub-pixels 112 are equal. If the materials used to make the first sub-pixels 111 and the second sub-pixels 112 have substantially the same lifespan, the first sub-pixels 111 and the second sub-pixels 112 have substantially the same service life. In this embodiment, the area ratio of the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 can be 1:1:2.

[0059] Second embodiment:

[0060] In this embodiment, the overall structure of the repeating unit 10 is the same as that of the first embodiment, except that the shapes and sizes of the first sub-pixel 111 and the second sub-pixel 112 are different from those of the first embodiment. Figure 4 As shown, the shapes of the first sub-pixel 111 and the second sub-pixel 112 are both trapezoidal, and the shape of the third sub-pixel 113 is a triangle. It can be understood that since the first quadrilateral 12 and the second quadrilateral 13 are both squares, and the first sub-pixel 111 and the second sub-pixel 112 each have a corner that coincides with a corner of the second quadrilateral 13, the shapes of the first sub-pixel 111 and the second sub-pixel 112 are both right trapezoids; at the same time, a corner of the third sub-pixel 113 coincides with a corner of the square first quadrilateral 12, so the shape of the third sub-pixel 113 can specifically be an isosceles right triangle.

[0061] like Figure 1 and Figure 4 As shown, adjacent first sub-pixels 111 and second sub-pixels 112 both have a common side (first common side D1), and one first sub-pixel 111 and one second sub-pixel 112 form half of a second quadrilateral 13. That is, with respect to the area of ​​half of the second quadrilateral 13, the shapes of one first sub-pixel 111 and one second sub-pixel 112 are complementary. Furthermore, in this embodiment, the area of ​​the second sub-pixel 112 is larger than that of the first sub-pixel 111. Since the service life of the materials currently used to make the second sub-pixel 112 is shorter than that of the materials used to make the area of ​​the first sub-pixel 111, the area of ​​the second sub-pixel 112 is made larger than that of the first sub-pixel 111. This balances the service lives of the first sub-pixel 111 and the second sub-pixel 112, ensuring that the service lives of the first sub-pixel 111 and the second sub-pixel 112 are consistent, thereby achieving the goal of optimizing the sub-pixel opening.

[0062] Third embodiment:

[0063] In this embodiment, within each repeating unit 10, the first sub-pixel 111 is a quadrilateral, the second sub-pixel 112 is a pentagon, and the third sub-pixel 113 is in the shape of a triangle or a quadrilateral, and the first sub-pixel 111 and the second sub-pixel 112 are both axially symmetrical figures; the two first sub-pixels 111 are arranged at intervals, and the two second sub-pixels 112 are arranged in close proximity or at intervals; wherein, when the two second sub-pixels 112 are arranged at intervals, the adjacent sides 1124 of the two second sub-pixels 112 arranged at intervals are parallel to each other; the area of ​​the second sub-pixel 112 is larger than the area of ​​the first sub-pixel 111.

[0064] Specifically, such as Figure 5 As shown, in the first structure of this embodiment, the third sub-pixel 113 is triangular in shape, the first sub-pixel 111 is a quadrilateral symmetrically arranged along the axis of symmetry of the repeating unit 10, and the two second sub-pixels 112 are arranged in abutment with each other, i.e., the two second sub-pixels 112 have a common side. The two first sub-pixels 111 are arranged on either side of the two abutment-arranged second sub-pixels 112, and are separated by the two second sub-pixels 112. Furthermore, in this structure, the area of ​​the second sub-pixel 112 is larger than that of the first sub-pixel 111.

[0065] like Figure 6 As shown, in the second structure of this embodiment, the shape of the third sub-pixel 113 can be a quadrilateral. This can be understood as, based on the first structure of this embodiment, the hypotenuse of the triangular third sub-pixel 113 in the pixel structure 100 is designed as a fold line, so that the shape of the third sub-pixel 113 in this structure is formed into a quadrilateral. The outer contour of the pattern formed by the two first sub-pixels 111 and the two second sub-pixels 112 can be a polygon, and each side of the polygon can be a fold line. For example, the polygon can be an octagon, and each side of the polygon is a fold line with a bend point.

[0066] like Figure 6 As shown, in the second structure of this embodiment, the first sub-pixel 111 is a quadrilateral symmetrically arranged along the symmetry axis of the repeating unit 10. The two second sub-pixels 112 are spaced apart, i.e., there is a gap 1123 between the two second sub-pixels 112. The adjacent sides 1124 of the two spaced apart second sub-pixels 112 are parallel to each other. The two first sub-pixels 111 are oppositely arranged on either side of the two spaced apart second sub-pixels 112 and are spaced apart by the two second sub-pixels 112. Similarly, in this structure, the area of ​​the second sub-pixels 112 is larger than the area of ​​the first sub-pixels 111.

[0067] Fourth embodiment:

[0068] In this embodiment, if Figure 7As shown, within each repeating unit 10, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are all polygonal in shape. One side of the first sub-pixel 111 overlaps with one side of the first quadrilateral 12; one side of the second sub-pixel 112 overlaps with another side of the first quadrilateral 12. That is, at least a portion of the first sub-pixel 111 along the column direction Y extends to a side of the first quadrilateral 12 formed by the repeating unit 10; and at least a portion of the second sub-pixel 112 along the row direction X extends to a side of the first quadrilateral 12.

[0069] Specifically, the fourth embodiment can be understood as the first embodiment with the area of ​​the first sub-pixel 111 and the second sub-pixel 112 enlarged and the area of ​​the third sub-pixel 113 reduced. Figure 7 As shown, in this embodiment, the area of ​​the first sub-pixel 111 is increased from a square to two triangular first extension areas 1111, resulting in the shape of the first sub-pixel 111 forming a polygonal shape consisting of a square and two triangles. Similarly, the area of ​​the second sub-pixel 112 is increased from a square to two triangular second extension areas 1121, resulting in the shape of the second sub-pixel 112 forming a polygonal shape consisting of a square and two triangles. Simultaneously, the area of ​​the third sub-pixel 113 is correspondingly reduced. The reduced area of ​​the third sub-pixel 113 is the third extension area 1112 at one corner of the first quadrilateral 12 and the fourth extension area 1122, thereby changing the shape of the third sub-pixel 113 from a right triangle to a polygonal shape, specifically a pentagon. In this embodiment, the area of ​​the first sub-pixel 111 is equal to the area of ​​the second sub-pixel 112, and both the area of ​​the first sub-pixel 111 and the area of ​​the second sub-pixel 112 are smaller than the area of ​​the third sub-pixel 113.

[0070] Through this deformed, irregular sub-pixel arrangement, adjacent pixel units 11 are rotationally symmetric, so the sub-pixels at the outermost edges of the pixel structure 100 can be arranged in a BRBBGB or BRBBGB arrangement along the column direction Y (viewed from the right side of the first repeating unit 101 to the second repeating unit 102 along the column direction Y), so that the colors of multiple sub-pixels are complementary after being illuminated, thereby solving the problem of display color fringing.

[0071] Fifth embodiment:

[0072] In this embodiment, if Figure 8As shown, within each repeating unit 10, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are all polygonal in shape. One side of the first sub-pixel 111 overlaps with one side of the first quadrilateral 12; one side of the second sub-pixel 112 overlaps with another side of the first quadrilateral 12. That is, at least a portion of the first sub-pixel 111 along the column direction Y extends to a side of the first quadrilateral 12 formed by the repeating unit 10; and at least a portion of the second sub-pixel 112 along the row direction X extends to a side of the first quadrilateral 12.

[0073] Specifically, the fifth embodiment can be understood as expanding the area of ​​the first sub-pixel 111 and the second sub-pixel 112 and reducing the area of ​​the third sub-pixel 113 on the basis of the first structure of the third embodiment. Figure 8 As shown, in this embodiment, the area of ​​the first subpixel 111 is increased from a quadrilateral to a polygonal shape with two triangular third extensions 1112. This results in the first subpixel 111 forming a polygonal shape consisting of a quadrilateral and two triangles. Similarly, the area of ​​the second subpixel 112 is increased from a quadrilateral to a polygonal shape consisting of two triangular fourth extensions 1122. This results in the second subpixel 112 forming a polygonal shape consisting of a quadrilateral and two triangles. Simultaneously, the area of ​​the third subpixel 113 is reduced accordingly. The reduction in area of ​​the third subpixel 113 is due to the third extension 1112 at one corner of the first quadrilateral 12 and the fourth extension 1122. This changes the shape of the third subpixel 113 from a right triangle to a polygonal shape, specifically a pentagon. In this embodiment, the area of ​​the first subpixel 111 is smaller than that of the second subpixel 112, which in turn is smaller than that of the third subpixel 113. Furthermore, in this embodiment, the two second subpixels 112 can be arranged adjacent to each other or spaced apart; the two first subpixels 111 are spaced apart.

[0074] Through this deformed and irregular sub-pixel arrangement, adjacent pixel units 11 are rotationally symmetric, so the sub-pixels at the outermost edges of the pixel structure 100 can be arranged in a BRBBGB or BRBBGB arrangement along the column direction Y (viewed from the right side of the first repeating unit 101 to the second repeating unit 102 along the column direction Y), so that the colors of multiple sub-pixels are complementary after being illuminated, thereby solving the problem of display color fringing.

[0075] In the third to fifth embodiments, by configuring the sub-pixels to be polygonal or irregular in shape and arranging a plurality of sub-pixels, the aliasing effect of the oblique display image in the display panel 300 can be effectively reduced.

[0076] The pixel structure 100 disclosed in the present application includes: a plurality of repeating units 10 arranged in an array along a row direction X and a column direction Y; wherein each repeating unit 10 includes two first sub-pixels 111, two second sub-pixels 112, and four third sub-pixels 113; wherein, within each repeating unit 10: the two first sub-pixels 111 and the two second sub-pixels 112 are arranged around a geometric center point O of the repeating unit 10, the two first sub-pixels 111 and the two second sub-pixels 112 are alternately arranged along the circumferential direction, and the circumferentially adjacent first sub-pixels 111 and second sub-pixels 112 have at least partially common edges; the four third sub-pixels 113 are arranged around the two first sub-pixels 111 and the two second sub-pixels 112; the area of ​​the first sub-pixel 111 and the area of ​​the second sub-pixel 112 are both smaller than the area of ​​the third sub-pixel 113; the area of ​​the second sub-pixel 112 is greater than or equal to the area of ​​the first sub-pixel 111; and the colors of the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are all different. The present application arranges the sub-pixels within the above-mentioned pixel area 1 and the repeating unit 10 so that each repeating unit 10 has a first sub-pixel 111, a second sub-pixel 112 and a third sub-pixel 113 in the horizontal, vertical and diagonal directions. When the sub-pixels are lit, the displayed colors will be complementary, so that the display panel 300 using this pixel structure 100 will not have the problem of color fringing when displaying, whether in the horizontal, vertical or diagonal directions, thereby improving the display effect.

[0077] The above-mentioned pixel structure 100 provided in the present application can, on the one hand, effectively improve the display effect of the display panel 300, and on the other hand, it also optimizes the arrangement of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113, balancing the service life of the above three sub-pixels. At the same time, the pixel structure 100 of the present application is not only applicable to the traditional FMM (fine metal mask) evaporation production method, but is also more suitable for application in the emerging photolithography (OH structure) method. The reason is that the traditional FMM has high requirements for the gap between sub-pixels, the opening loss is large, and the opening utilization rate is low. The emerging photolithography (OH structure) method, for the situation where the sub-pixels are arranged relatively full in the present application, the OH structure area is very small, which is more conducive to the arrangement of sub-pixels, the opening loss is very small, and the display effect is better. The pixel structure 100 of the present application refines the arrangement of each RGB sub-pixel, the ratio of the pixel unit 11 and the arrangement of the RGB sub-pixels, so as to achieve a relatively uniform RGB arrangement in all directions, so that the jaggedness and color edge of the displayed image are optimized, further improving the quality of the displayed image and enhancing the visual experience of the image.

[0078] In order to solve the above problems, the present application also provides a display panel 300 .

[0081] The panel driving circuit 200 includes a source driving circuit 201 and a gate driving circuit 202. The source driving circuit 201 and the gate driving circuit 202 are respectively located on the sides of the pixel structure 100.

[0082] The source driver circuit 201 is connected to the pixel structure 100 and is used to provide data voltages to the pixel units in the pixel structure 100 so that the display panel 300 displays images. The gate driver circuit 202 is connected to the pixel structure 100 and is used to provide driving signals to the pixel driver circuit in the pixel structure 100.
