In order to make the technical problems, technical solutions and effects of the present invention more apparent, the following description of the preferred embodiments of the present invention with reference to the accompanying drawings is provided, and it should be understood that the preferred embodiments described herein are only for illustrating and explaining the present invention and are not to be used for limiting the present invention. And the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In a first organic light emitting diode OLED pixel arrangement structure provided in an embodiment of the present invention, as shown in fig. 2, a pixel array formed by the OLED pixel arrangement structure includes: a plurality of emission pixels 100 adjacent to each other, wherein, if the pixel row direction is the horizontal direction, the emission pixels 100 in the same row are sequentially and repeatedly arranged along the horizontal direction, and the emission pixels 100 in adjacent rows are mutually staggered and seamlessly spliced; each of the emission pixels 100 includes a red light emitting region, a green light emitting region, and a blue light emitting region, which have three equal areas, and the red light emitting region, the green light emitting region, and the blue light emitting region in each of the emission pixels are arranged in the same manner.

Alternatively, in each emission pixel 100, the positional relationship of the trisected red light-emitting regions, green light-emitting regions, and blue light-emitting regions may be variously combined, not limited to the pixel arrangement shown in fig. 2.
Since the areas of the red light emitting areas in each emitting pixel 100 are equal and the relative positions are the same, when forming the sub-pixels in the red light emitting area in each emitting pixel 100, a plurality of sub-pixels in the red light emitting area in the emitting pixels can be formed by evaporation by using one evaporation mask.

In other words, the green sub-pixel and the blue sub-pixel at the top corner of the second emission pixel 300 are adjacent to the red sub-pixel at the bottom corner of the adjacent second emission pixel 300 in an interlaced manner.
In the horizontal direction, the pixel structure in which the first emission pixels 200 and the second emission pixels 300 are staggered with each other is a pixel row, and the pixel arrangement of each pixel row is the same.
In the above embodiment, for each sub-pixel, except for the sub-pixels at the edge of the display area, each sub-pixel is adjacent to 6 sub-pixels, and the color of any two sub-pixels adjacent to each other is different, for example, the blue sub-pixel is adjacent to 6 sub-pixels, and includes 3 red sub-pixels and 3 green sub-pixels, where the red sub-pixels and the green sub-pixels are adjacent to each other. Similarly, the green sub-pixel is adjacent to the 6 sub-pixels, and comprises 3 red sub-pixels and 3 blue sub-pixels, wherein the red sub-pixels and the blue sub-pixels are adjacent to each other.

In addition, since the areas of the red light emitting regions are equal in all of the first emitting pixels 200 and the second emitting pixels 300, and the positions of the red light emitting regions in the first emitting pixels 200 or the second emitting pixels 300 are relatively fixed, when forming the red sub-pixels in the red light emitting regions, a plurality of sub-pixels in the red light emitting regions can be formed by vapor deposition using one vapor deposition mask. Similarly, when forming the green sub-pixels in each green light emitting area, a plurality of sub-pixels in the green light emitting area can be formed by evaporation by using one evaporation mask. Similarly, when forming the blue sub-pixels in each blue light-emitting area, a plurality of sub-pixels in the blue light-emitting area can be formed by evaporation by using one evaporation mask. Therefore, the manufacturing of the pixel arrangement structure of the OLED pixel arrangement can be completed only by three evaporation masks, and the manufacturing process difficulty of the pixel array is favorably reduced.
In addition, the pixel arrangement shown in fig. 3 has an additional technical effect: compared with the pixel arrangement shown in fig. 2, the size of each sub-pixel is the same as that of each emission pixel in the pixel arrangement shown in fig. 2, so that the size of the first emission pixel 200 or the second emission pixel 300 formed by the red sub-pixel, the green sub-pixel and the blue sub-pixel is 3 times that of the emission pixel shown in fig. 2, therefore, when an opening is made, the opening area of each emission pixel can be increased by one time, on the basis of increasing the opening area, the display brightness can be increased on the basis of not increasing the power supply voltage, the display resolution is improved, on the basis of the same brightness requirement, the power supply voltage can be reduced, and the power loss is reduced.

Wherein the arrangement of the 3 blue sub-pixels in the blue light emitting area is the same as the arrangement of the 3 green sub-pixels in the green light emitting area.
In the pixel structure shown in fig. 4, the areas of the red light emitting areas are all equal, the positions of the red light emitting areas in the pixel array are relatively fixed, and the arrangement of the 3 red sub-pixels in each red light emitting area is the same, so that when the 3 red sub-pixels in each red light emitting area are formed, a plurality of sub-pixels in the red light emitting areas can be formed by evaporation by using one evaporation mask. Similarly, when forming the green sub-pixels in each green light emitting area, a plurality of sub-pixels in the green light emitting area can be formed by evaporation by using one evaporation mask. Similarly, when forming the blue sub-pixels in each blue light-emitting area, a plurality of sub-pixels in the blue light-emitting area can be formed by evaporation by using one evaporation mask. Therefore, the manufacturing of the pixel arrangement structure of the OLED pixel arrangement can be completed only by three evaporation masks, and the manufacturing process difficulty of the pixel array is favorably reduced.
In addition, the pixel arrangement shown in fig. 4 has an additional technical effect: compared with the pixel arrangement shown in fig. 2, the size of each sub-pixel is the same as that of each emission pixel in the pixel arrangement shown in fig. 2, so that the size of the emission pixel formed by the red light emitting area, the green light emitting area and the blue light emitting area is 6 times that of the emission pixel shown in fig. 2, therefore, when the opening is made, the opening area of each light emitting area can be increased by 3 times, on the basis of increasing the opening area, the display brightness can be increased on the basis of not increasing the power supply voltage, the display resolution is improved, under the same brightness requirement, the power supply voltage can be reduced, and the power consumption is reduced.
