According to the pixel arrangement structure provided by the embodiment of the application, three sub-pixels with different light emitting colors are arranged in the pixel area 10, at least two sub-pixels of the three sub-pixels are respectively adjacent to the edge of the pixel area 10, when a plurality of pixel areas 10 are arranged together, one edge of each of two adjacent pixel areas 10 is overlapped to form an overlapped edge, and two sub-pixels which are respectively located in two adjacent pixel areas 10 and have the same light emitting color as the two adjacent overlapped edges are combined together; the sub-pixels with the same light emission color in different pixel regions 10 are combined together to reduce the gaps formed between the sub-pixels, so that the number of the sub-pixels arranged in the same area is increased, the light emission area is increased, the pixel density is increased, and the effect of high resolution is achieved.

In one embodiment, referring to fig. 1, 6 and 8, the three sub-pixels with different emission colors are a first sub-pixel 101, a second sub-pixel 102 and a third sub-pixel 103; a second sub-pixel 102 is arranged in the pixel region 10, and the second sub-pixel 102 is spaced from the edge of the pixel region 10 by a preset length; the first sub-pixel 101 is adjacent to the edge of the pixel region 10; the third sub-pixel 103 is adjacent to the edge of the pixel region 10.

Through the arrangement, only one second sub-pixel 102 is arranged in the pixel area 10, the second sub-pixel 102 is spaced from the edge of the pixel area 10 by the preset length, and the first sub-pixel 101 and the third sub-pixel 103 arranged in the pixel area 10 are adjacent to the edge of the pixel area 10, so that a plurality of pixel combinations consisting of the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 in the pixel area 10 share the same second sub-pixel 102, and the pixel utilization rate is improved.

Optionally, the arrangement position of the second sub-pixel 102 in the pixel region 10 may be that the central point of the second sub-pixel 102 coincides with the central point of the pixel region 10, or the central point of the second sub-pixel 102 does not coincide with the central point of the pixel region 10, as long as the requirement of the preset length of the edge interval between the second sub-pixel 102 and the pixel region 10 is met.

The areas of the first subpixel 101, the second subpixel 102, and the third subpixel 103 are not particularly limited, and may be selected as needed, and it is preferable that the areas of the subpixels of the same emission color be the same, and the areas of the subpixels of different emission colors be the same or different.

In one embodiment, referring to fig. 1, 6, and 8, the pixel region 10 has a rectangular shape; preferably square; the first sub-pixel 101 is disposed at two diagonal corners among four corners of the pixel region 10, and the first sub-pixel 101 is adjacent to two sides of the corner; the third sub-pixel 103 is disposed at the corner of the remaining two opposite corners of the four corners of the pixel region 10, the third sub-pixel 103 is adjacent to one of the corners extending along the first direction, and the third sub-pixel 103 is spaced from the other corner extending along the second direction by a predetermined length; the first direction is one of a row direction and a column direction, and the second direction is the other of the row direction and the column direction.

With the above arrangement, the first sub-pixel 101 and the third sub-pixel 103 are disposed at the corner of the pixel group, and the first sub-pixel 101 is adjacent to both sides of the corner, the third sub-pixel 103 is adjacent to one side of the corner extending along the first direction, and the third sub-pixel 103 is spaced from the other side of the corner extending along the second direction by a predetermined length, so that the first sub-pixels 101 in the two adjacent pixel groups are adjacent to each other, the third sub-pixels 103 in the two adjacent pixel groups are adjacent to each other along the first direction, the two first sub-pixels 101 and the two third sub-pixels 103 are adjacent to each other, so as to reduce the gap formed between the sub-pixels, reduce the area of non-light emission, thereby increase the light-emitting area, and the first sub-pixels 101 and the third sub-pixels 103 adjacent to each other can be used together, so as to increase the light-emitting area, the pixel density is improved, and the effect of high resolution is achieved.

Furthermore, two first sub-pixels 101 are arranged in the pixel area 10 in a diagonal manner, and two third sub-pixels 103 are arranged in the pixel area 10 in a diagonal manner, so that different sub-pixels can be arranged in a staggered manner, which is beneficial to increasing the light-emitting area, the light-emitting area is increased, so that the opening area of the metal mask plate for manufacturing the pixel arrangement structure is larger, the opening ratio is improved, the strength of the metal mask plate is increased, the service life is prolonged, the service life of the display is prolonged, and the image quality definition of the display screen is improved.

Referring to fig. 1, in the pixel arrangement structure of the embodiment of the present application, each sub-pixel can emit light independently, four adjacent second sub-pixels 102 are disposed around each of the merged first sub-pixels 101, and the merged first sub-pixels 101 can determine whether to display according to the display conditions of the four second sub-pixels 102 during the display process; each group of two nearest-neighbor third sub-pixels 103 combined together has four neighboring second sub-pixels 102 around, and the third sub-pixels 103 combined together in the display process can decide whether to display or not to display one of the three sub-pixels according to the display condition of the four second sub-pixels 102.

Referring to fig. 2 and 3, four pixel regions 10 arbitrarily adjacent to each other constitute a pixel unit 100; the center point of the graph formed by taking one first sub-pixel 101 from any adjacent four pixel areas 10 is coincided with the center point of the pixel unit 100, or the center point of the graph formed by taking one third sub-pixel 103 from any adjacent four pixel areas 10 is coincided with the center point of the pixel unit 100.

In the above arrangement, as shown in fig. 2, since the first sub-pixels 101 and the third sub-pixels 103 are arranged diagonally in the pixel regions 10, there are two first sub-pixels 101 in each pixel region 10, the center point of the graph formed by one first sub-pixel 101 from any adjacent four pixel regions 10 coincides with the center point of the pixel unit 100, there are two third sub-pixels 103 in each pixel region 10, the center point of the graph formed by one third sub-pixel 103 from any adjacent four pixel regions 10 coincides with the center point of the side of the pixel unit 100, as shown in fig. 3, there are two third sub-pixels 103 in each pixel region 10, the center point of the graph formed by one third sub-pixel 103 from any adjacent four pixel regions 10 coincides with the center point of the pixel unit 100, and there are two first sub-pixels 101 in each pixel region 10, the center point of the graph formed by one first sub-pixel 101 is taken from any adjacent four pixel areas 10 and is coincided with the center point of the edge of the pixel unit 100. The pixel units 100 in the above two arrangement modes can be repeatedly arranged to form the pixel arrangement structure of this embodiment, and after the plurality of pixel units 100 are repeatedly arranged together, the edges of two adjacent pixel units 100 are overlapped, and sub-pixels with the same light emitting color can be combined to form a complete light emitting region, which is beneficial to improving the display resolution.

The pixel arrangement structure of the embodiment of the present application may be formed by repeatedly arranging the pixel units 100 in a plurality of rows, the number of the pixel units 100 is not particularly limited, and may be any integer greater than 2, and two adjacent pixel units 100 are arranged in an edge-to-edge manner, and it can be understood that the "edge-to-edge" arrangement mode means that two adjacent edges are opposite to each other, and preferably, two edges are parallel or overlapped with each other, so that the same sub-pixels in adjacent positions in each pixel unit 100 are merged together to form a light emitting area with a regular shape. Here, the light emitting region refers to a region capable of emitting light of a specific color. The first sub-pixel 101 and the third sub-pixel 103 in two adjacent pixel units 100 are respectively combined together to emit light, so that the same sub-pixel in different pixel units 100 can be printed together, the deposition area of ink can be increased in multiples, the size of each sub-pixel can be effectively reduced, and the ink can not overflow due to the fact that the area of the pixel is too small, so that high-resolution display can be achieved under the same equipment precision. In the actual display process, the first sub-pixel 101 and the third sub-pixel 103 in two adjacent pixel units 100 are respectively merged together to form a new-shaped sub-pixel, and the two adjacent pixel units 100 share pixels, so that the display effect can be further improved by adopting a sub-pixel rendering mode.

In fig. 1, the central point of the graph formed by one of the first sub-pixels 101 is taken as P from any adjacent four pixel regions 10, the central point of the graph formed by one of the third sub-pixels 103 is taken as N from any adjacent four pixel regions 10, and the central point of the second sub-pixel 102 is taken as O; the connecting line between P and O is vertical to the connecting line between N and O.

It is understood that the sub-pixels correspond to the light emitting units, and can emit light of different colors according to the types of the light emitting units, which can be color combinations of common display units, such as red, blue, and green combinations. In one embodiment, the first sub-pixel 101 is a red sub-pixel, the second sub-pixel 102 is a blue sub-pixel, and the third sub-pixel 103 is a green sub-pixel. It should be noted that, in fig. 1-8, the first sub-pixel 101 is labeled as R, the second sub-pixel 102 is labeled as B, and the third sub-pixel 103 is labeled as G. Of course, in the pixel arrangement structure of other displays, the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 may emit different colors of light. For example, the third subpixel 103 may emit white light.

In one embodiment, optionally, the area of the first sub-pixel 101 is larger than the area of the third sub-pixel 103, and the area of the second sub-pixel 102 is larger than the area of the first sub-pixel 101.

Through the above arrangement, the area of the first sub-pixel 101 is larger than the area of the third sub-pixel 103, the area of the second sub-pixel 102 is larger than the area of the first sub-pixel 101, that is, the area of the red sub-pixel is larger than the area of the green sub-pixel, and the area of the blue sub-pixel is larger than the area of the red sub-pixel, so the area of the green sub-pixel is the smallest.

Further, since the second sub-pixel 102 emitting blue light among the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 has the shortest lifetime, the second sub-pixel 102 having a larger area than the third sub-pixel 103 may effectively suppress the lifetime reduction of the display, that is, may improve the lifetime of the display.

In one embodiment, referring to fig. 1-8, the shapes of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 are all different; in an actual manufacturing process, among the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103, power lines (for example, gate lines, data lines, driving power lines, and the like) for driving each sub-pixel may be disposed, and further, an insulating layer for defining each sub-pixel, such as a pixel defining layer, may be disposed, and finally, an OLED including an anode, an organic emission layer, and a cathode, which correspond to each of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103, may be disposed, so that the shape of each sub-pixel may be defined by the power lines, the pixel defining layer, the anode, and the like, but the shape of each sub-pixel is not limited thereto.

Referring to fig. 1 to 5, the first sub-pixel 101 is shaped like a sector, a figure formed by taking one first sub-pixel 101 from any adjacent four pixel regions 10 is a circle, the second sub-pixel 102 is shaped like a regular octagon, the third sub-pixel 103 is shaped like a quadrangle, and a figure formed by combining two third sub-pixels 103 located at adjacent positions is shaped like a pentagon. Referring to fig. 6, the shape of the first sub-pixel 101 is a graph formed by a curve and two straight lines passing through two ends of the curve, and the graph formed by taking one third sub-pixel 103 from any adjacent four pixel regions 10 is an ellipse; the second sub-pixel 102 is in the shape of a regular hexagon, the third sub-pixel 103 is in the shape of a quadrangle, and the shape of a figure formed by combining two adjacent third sub-pixels 103 is a pentagon. Referring to fig. 8, the first subpixel 101 has a fan shape, the second subpixel 102 has a regular hexagonal shape, and the third subpixel 103 has a quadrangular shape.

With the above arrangement, the first sub-pixel 101 and the third sub-pixel 103 can make full use of the pixel gap, and improve the pixel density and the light emitting efficiency.

Referring to fig. 7, a distance between two adjacent second sub-pixels 102 in the row direction is a first length L1, a distance between two adjacent second sub-pixels 102 in the column direction is a third length L3, distances between every two adjacent first sub-pixels 101 and second sub-pixels 102 are the same, and are all the second length L2, a distance between a third sub-pixel 103 and a second sub-pixel 102 is a fourth length L4, a distance between two adjacent third sub-pixels 103 in the column direction is a fifth length L5, and further, L1 is longer than L2, and L5 is shorter than L1. It should be noted that L1, L2, L3, L3, L4, L5 may be used throughout to represent the shortest distance between the respective sub-pixels.

Accordingly, when a fine metal mask is used to form red, blue, and green organic emission layers respectively included in the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103, deposition reliability will be improved.

In addition, by surrounding each of the first sub-pixels 101 with a pair of the second sub-pixels 102 and a pair of the third sub-pixels 103, the aperture ratio of the first sub-pixels 101, the second sub-pixels 102, and the third sub-pixels 103 can be improved, the manufacturing time and manufacturing cost of the entire display can be effectively reduced, and the display quality of the image of the display can be improved. Further, it is considered that the deposition process of the organic emission layer is one of unique manufacturing characteristics of the OLED display, and thus, in order to improve the deposition reliability of the organic emission layer using a fine metal mask during the deposition process and to improve the aperture ratio of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103, the center point of each pattern composed of one of the first sub-pixels 101 from any adjacent four pixel regions 10 and the center point of each pattern composed of one of the third sub-pixels 103 from any adjacent four pixel regions 10 are located at the vertices of the pixel regions 10.

In one embodiment, optionally, the distance between the center points of two adjacent second sub-pixels 102 is greater than the side length of the third sub-pixel 103. Through the arrangement, the area of the second sub-pixel 102 can be ensured to be larger than that of the third sub-pixel 103, and the third sub-pixel 103 is clamped between two adjacent second sub-pixels 102 to form a structure that the sub-pixels are alternately arranged, so that the positions of the sub-pixels are more reasonably arranged and arranged, and the area of a light-emitting region is increased.
