Fig. 1 shows a schematic structure diagram of a conventional Real pixel structure. The rectangular structures located inside in fig. 1 are a sub-pixel R, a sub-pixel G, and a sub-pixel B, and for convenience of description, the sides of the rectangular structures are referred to as the sides of the sub-pixels. The rectangular sides located outside the rectangular structure of the sub-pixels R, G, and B are referred to as reserved sides (i.e., Mask edges in the formation of a Mask process). The area between the pixel edge and the reserved edge constitutes the spacing area between the pixel openings. These large spacing regions, in turn, compress the display area of the pixel, resulting in a lower aperture ratio of the pixel.
As shown in fig. 1, the Real pixel structure is arranged with the pixels juxtaposed, and its PPI is always low.
In view of the above problems, the present invention provides a display panel and a pixel arrangement structure thereof to improve the PPI of the pixels of the display panel, thereby improving the picture quality of the display panel.
Fig. 2 is a schematic structural diagram illustrating a pixel arrangement structure of the display panel 10 according to an embodiment of the present invention.
Referring to fig. 2, a pixel arrangement structure of a display panel 10 according to an embodiment of the present invention includes one or more repeating units 10 a.
Each repeating unit 10a includes at least one pixel group 101. In some embodiments, each of the repeating units 10a includes two pixel groups 101 adjacently arranged along the first direction 01.
Each pixel group 101 includes two first sub-pixels 11, two second sub-pixels 12, and a third sub-pixel 13. The first subpixel 11 and the second subpixel 12 have different light emitting areas.
The two first sub-pixels 11 and the two second sub-pixels 12 are arranged around the third sub-pixel 13, the two first sub-pixels 11 are arranged in one row along the first direction 01, and the two second sub-pixels 12 are arranged in the other row along the first direction 01.
The pixel arrangement structure of the display panel 10, on one hand, is beneficial to individually controlling the total light emitting area of each color sub-pixel in each pixel group 101 by limiting the number and light emitting area of the sub-pixels in the repeating unit 10a, so as to adapt to sub-pixels with different lifetimes and reduce the color cast of viewing angles. On the other hand, two first sub-pixels 11 and two second sub-pixels 12 are arranged around the third sub-pixel 13, so that the third sub-pixel 13 can be shared twice, and two pixel units (as shown by the dashed triangle frame in fig. 2) are formed with the first sub-pixel 11 and the second sub-pixel 12 located around the third sub-pixel 13, and higher PPI can be simulated through pixel sharing, thereby improving the picture quality; therefore, the process difficulty and the cost of the precise metal mask plate can be reduced. Two first sub-pixels 11 or two second sub-pixels 12 sequentially arranged in the first direction 01 may share the evaporation opening, and the pixel aperture ratio may be increased. And the first sub-pixels 11 and the second sub-pixels 12 in each pixel group 101 are respectively arranged in a row, so that the first sub-pixels 11 and the second sub-pixels 12 are not shared, the rendering-induced unreality is reduced, and the display reality is improved.
In one embodiment, if the light-emitting area of the first sub-pixel 11 is a, the light-emitting area of the second sub-pixel 12 is b, and the light-emitting area of the third sub-pixel 13 is c, then 2b > c ≧ 2 a; preferably 2b > c >2 a. Preferably, the first sub-pixel 11 is a green sub-pixel, the second sub-pixel 12 is a blue sub-pixel, and the third sub-pixel 13 is a red sub-pixel. Therefore, the area of the blue sub-pixel in the pixel arrangement structure is larger than that of the red and green sub-pixels, so that the problem of visual angle color cast caused by the sequentially decreasing service lives of the red, green and blue sub-pixels is favorably solved.
In some embodiments, the two first sub-pixels 11 in each pixel group 101 are symmetrically arranged with an extension line of a center line of the third sub-pixel 12 along the second direction 02 as a symmetry axis; the two second sub-pixels 12 in each pixel group 101 are symmetrically arranged with an extension line of a center line of the third sub-pixel 13 along the second direction 02 as a symmetry axis.
Further, one first sub-pixel 11 and one second sub-pixel 12 in each repeating unit 10a are sequentially arranged in the second direction 02, and the other first sub-pixel 11 and the other second sub-pixel 12 are also sequentially arranged in the second direction 02.
It can be understood that the light emitting colors of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are different and are respectively selected from one of red, green and blue.
Further, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are all polygonal structures.
In the present specific example, each pixel group 101 has a rectangular structure, and two first sub-pixels 11 and two second sub-pixels 12 are respectively configured at four corners of the rectangular structure. Therefore, the arrangement of each sub-pixel is compact, the space utilization is reasonable, and the aperture opening ratio is favorably improved.
In some examples, the third sub-pixel 13 has a quadrangular or hexagonal structure, preferably a rhombic structure. Along the first direction 01, the bisector of the third sub-pixel 13 is less than or equal to the side length of the rectangular structure. Along the second direction 02, the bisector of the third sub-pixel 13 is smaller than the side length of the rectangular structure, preferably equal to or smaller than 2/3, and more preferably equal to (1/4-2/3), wherein two points 1/4 and 2/3 are included.
It is understood that in other examples, the third sub-pixel 13 may also have a triangular structure (as shown in fig. 5).
Further, the first sub-pixel 11 and the third sub-pixel 13 are disposed side by side. The second sub-pixel 12 is arranged edge-to-edge with the third sub-pixel 13.
Furthermore, two opposite edges of the first sub-pixel 11 and the third sub-pixel 12 are parallel to each other, and the other edges of the first sub-pixel 11 are not parallel to the adjacent edges of the third sub-pixel 13. Two opposite edges of the second sub-pixel 12 and the third sub-pixel 13 are parallel to each other, and the other edges of the second sub-pixel 12 are not parallel to the adjacent edges of the third sub-pixel 13.
In the example shown in fig. 2, two sides of the first sub-pixel 11 in the first and second directions 01 and 02 and two sides of the second sub-pixel 12 in the first and second directions 01 and 02 constitute boundaries of the light emitting region of the pixel group 101. Preferably, in each pixel group 101, the first sub-pixel 11 and the second sub-pixel 12 respectively include a side parallel to the first direction 01 and a side parallel to the second direction 02; wherein the first direction 01 is perpendicular to the second direction 02.
In some embodiments, the first sub-pixel 11 and the second sub-pixel 12 are polygon structures with different numbers of edges.
Further, one of the first sub-pixel 11 and the second sub-pixel 12 has a quadrilateral structure, and the other sub-pixel has a triangular structure.
In this specific example, one of the first sub-pixel 11 and the second sub-pixel 12 has a right trapezoid structure, and the other sub-pixel has a triangle structure.
Preferably, the corners and the opposite corners of the two triangular sub-pixels in the same pixel group 101 are integrally formed. Specifically, as shown in fig. 2, two first sub-pixels 11 are in a triangular structure, a second sub-pixel 12 is in a right trapezoid shape, and a third sub-pixel 13 is in a diamond shape. Wherein two corners of the first sub-pixels 11 of the two triangular structures are opposite to each other, so that the two first sub-pixels 11 have adjacency.
It will be appreciated that the shape of the sub-pixels is not limited thereto, and that some variations may be made, for example, two adjacent sides of the triangle structure may be linked by another oblique side, or may be linked by an arc side, so that the triangle expands into a hexagon. For example, a quadrilateral can also be expanded in this way to an octagon.
Further, the center point of the third subpixel 13 does not coincide with the center point of the pixel group 101. And, the center point of the third subpixel 13 is closer to the first subpixel 11 than the second subpixel 12. The distance from the center point of the third sub-pixel 13 to the center point of the first sub-pixel 11 is not equal to the distance from the center point of the second sub-pixel 12.
It should be noted that: first, the first direction 01 and the second direction 02 are not limited to the first direction 01 being a row direction and the second direction 02 being a column direction as shown in fig. 2, but in other embodiments, the first direction 01 may be a column direction and the second direction 02 may be a row direction; second, the rows described herein may be rows or columns that are aligned with the first direction 01 and/or the second direction 02.
In the example shown in fig. 2, each of the repeating units 10a includes two pixel groups 101, and the arrangement of one pixel group 101 after being turned 180 degrees in the first direction 01 is the same as the arrangement of another pixel group 101 in the same repeating unit 10 a. In this way, two adjacent first sub-pixels 11 of two pixel groups 101 in each repeating unit 10a are arranged in a staggered manner in the first direction 01, and two adjacent second sub-pixels 12 of two adjacent pixel groups 101 are arranged in a staggered manner in the first direction 01.
The arrangement structure of one pixel group 101 in each repeating unit 10a after being turned 180 degrees along the first direction 01 is the same as that of the other pixel group 101 in the same repeating unit 10a, so that the first sub-pixels 11 and the second sub-pixels 12 can be prevented from being continuously arranged in the same row, the mesh opening difficulty is reduced, and the display uniformity is improved.
Wherein the plurality of repeating units 10a are arranged in an array. Namely: the plurality of repeating units are arranged in an array of rows and columns along the first direction 01 and the second direction 02. The first direction 01 is the row or column direction of the array.
Further, every two first sub-pixels 11 and every two second sub-pixels 12 are alternately arranged in the first direction 01; in the second direction 02, one first sub-pixel 11 and one second sub-pixel 12 are alternately arranged.
Thus, the plurality of repeating units 10a are arranged in an array, on one hand, openings of evaporation masks of the sub-pixels are distributed more uniformly, the opening net is beneficial, on the other hand, the sub-pixels are distributed more uniformly, and the display effect can be better improved. Further, two first sub-pixels 11 sequentially arranged in the first direction 01 in each pixel group 101 are adjacent to each other, and two second sub-pixels 12 sequentially arranged in the first direction 01 are adjacent to each other.
Fig. 3 is a schematic structural diagram illustrating a pixel arrangement structure of a display panel according to still another embodiment of the present invention.
Referring to fig. 3, a pixel arrangement structure of the display panel 20 according to the first embodiment of the present invention is substantially the same as the pixel arrangement structure of the display panel 10 shown in fig. 2, and includes a plurality of repeating unit rows, each repeating unit 20a in each repeating unit row is sequentially arranged along a first direction 01, and the plurality of repeating unit rows are sequentially arranged along a second direction 02; the difference lies in that: the adjacent two of the repeating units 20a located in the two adjacent repeating unit rows in the second direction 02 are arranged with a shift. Wherein the first direction 01 and the second direction 02 are perpendicular to each other.
In the pixel arrangement structure of the display panel 20, since the two adjacent repeating units 20a in the second direction 02 are arranged in a staggered manner, the first sub-pixels 21 or the second sub-pixels 22 in the two adjacent repeating units 20a in the second direction 02 are in contact with each other, so that the four first sub-pixels 21 or the four second sub-pixels 22 in the two repeating units 20a can share one Mask opening during evaporation (as shown by a dashed line box in fig. 3), thereby reducing the area lost by the pixel design margin and increasing the aperture ratio. In addition, the openings of the mask corresponding to the first sub-pixel 21 and the second sub-pixel 22 are shown by the dashed line in fig. 3, which may be beneficial to reducing the tension of the alignment of the mask.
In some embodiments, in the second direction 02, the pixel structures of any two odd rows of the repeating unit rows are the same, the pixel structures of any two even rows of the repeating unit rows are the same, and two adjacent repeating units 20a of two adjacent rows are arranged in a staggered manner.
In some embodiments, two adjacent repeating units 20 in the second direction 02 are arranged offset by a distance of half a pixel group 201 in the first direction 01. Further, two adjacent repeating units 20a of two adjacent rows are arranged shifted by a distance of half the pixel group 201 in the first direction 01. Namely: the repeating unit 20a in the repeating unit line between the odd line and the even line is shifted by a distance of half the pixel group 201 in the first direction 01.
Further, two adjacent third sub-pixels 23 of two adjacent rows are arranged in a staggered manner. It can be understood that, since the pixel structures of the repeating unit rows of the odd-numbered rows are the same and the pixel structures of the repeating unit rows of the even-numbered rows are the same in the second direction 02, the third sub-pixels 23 of the repeating unit rows of the odd-numbered rows or the even-numbered rows are arranged on the same straight line in the second direction 02.
Further, an extension line of the center line of the third sub-pixel 23 of one pixel group 201 of any repeating unit row in the second direction 02 coincides with a boundary line between the adjacent two pixel groups 201 of the adjacent row.
It is to be understood that, since two adjacent pixel groups 201 share one edge, the shared edge is a boundary line of the pixel groups 201, but the "boundary" or "boundary line" herein is not limited to a physical "boundary" or "boundary line", but may refer to a virtual "boundary" or "boundary line" between two pixel groups 201.
Further, in each pixel group 101, one first sub-pixel 21 and one second sub-pixel 22 are sequentially arranged in the second direction 01, and the other first sub-pixel 21 and the other second sub-pixel 22 are sequentially arranged in the second direction 02;
the first sub-pixel 21 and the second sub-pixel 22 arranged in the second direction 02 in any one of the repeating unit rows are positioned on the same line as the first sub-pixel 21 and the second sub-pixel 22 arranged in the second direction 02 of the adjacent pixel group 101 of the adjacent row.
Such that the first sub-pixels 21 and the second sub-pixels 22 are alternately arranged in the second direction 02, specifically, a portion is alternately arranged in the second direction 02 in sequence with one first sub-pixel 21 and one second sub-pixel 22; a part of the first sub-pixels 21 and the second sub-pixels 22 are alternately arranged in the second direction 02.

Referring to fig. 4, a pixel arrangement structure of a display panel 30 according to a first embodiment of the present invention is substantially the same as the pixel arrangement structure of the display panel 10 shown in fig. 2, except that: the first subpixel 31, the second subpixel 32, and the third subpixel 33 of the pixel group 301 in each repeating unit 30a are all quadrilateral. Further, the first sub-pixel 31, the second sub-pixel 32, and the third sub-pixel 33 are all rectangular and have different areas.
Further, if the light emitting area of the first sub-pixel 31 is a, the light emitting area of the second sub-pixel 32 is b, and the light emitting area of the third sub-pixel 33 is c, then 2b > c is not less than 2 a; preferably 2b > c >2 a. Preferably, the first sub-pixel 31 is a green sub-pixel, the second sub-pixel 32 is a blue sub-pixel, and the third sub-pixel 33 is a red sub-pixel.
Fig. 5 is a schematic structural diagram illustrating a pixel arrangement structure of a display panel according to still another embodiment of the present invention.

Further, the first sub-pixel 41 has a rectangular shape, and the second sub-pixel 42 has a right trapezoid shape.
Further, if the light emitting area of the first sub-pixel 41 is a, the light emitting area of the second sub-pixel 42 is b, and the light emitting area of the third sub-pixel 43 is c, then 2b > c is greater than or equal to 2 a; preferably 2b > c >2 a. Preferably, the first sub-pixel 41 is a green sub-pixel, the second sub-pixel 42 is a blue sub-pixel, and the third sub-pixel 43 is a red sub-pixel.
