OLED pixel arrangement structure and vapor-deposition mask of pixel arrangement structure

Abstract

The invention relates to an OLED pixel arrangement structure and a vapor-deposition mask of the pixel arrangement structure, which belongs to the technical field of electronic equipment. RGB sub-pixels in the pixel array of the OLED pixel arrangement structure are hexagonal and are in a honeycomb distribution. One sub-pixel of any color in each pixel forms a same-color sub-pixel group together with two same-color sub-pixels just adjacent to the above sub-pixel. Based on the above novel pixel arrangement mode, the distance between different-color sub-pixels is maximized in the condition of high resolution. Therefore, the problem that the line of a mask is broken or the mask cannot be expanded can be solved. Based on the vapor-deposition mask, one through hole is shared by the same-color sub-pixel group, so that the spacing between the through holes of the mask is enlarged. Therefore, the alignment space is expanded, and the process difficulty is reduced. The occurrence of color-mixing defects is avoided. Furthermore, the product yield is improved and the production cost is lowered.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to the technical field of liquid crystal display panels, and specifically refers to an OLED pixel arrangement structure and an evaporation mask of the pixel arrangement structure. Background technique [0002] The pixels of traditional displays use such as figure 1 In the shown RGB sidebyside arrangement, the sub-pixels RGB are arranged sequentially in the horizontal direction. At high resolution, because the pixels of the same color are too close together, such as image 3 In the manufacture of the OLED mask (shadowmask) shown, there may be problems of disconnection L or failure to open the net. At the same time, if figure 2 and image 3 As shown, because the distances between different colors are very close, the alignment space S is limited, the technical process is difficult, and color mixing defects are prone to occur during the production of panel evap...
