Pixel arrangement structure, display panel and mask plate group

Abstract

The invention provides a pixel arrangement structure, a display panel and a mask plate group. The pixel arrangement structure comprises first sub-pixels, second sub-pixels and third sub-pixels, wherein the positions of the sub-pixels are not overlapped. The first sub-pixels are located at four vertexes of the virtual square and diagonal intersection points of the virtual square, and the virtual square is divided into four triangular areas by first diagonals and second diagonals; the second sub-pixels are located on the first diagonal line; the third sub-pixels are arranged near the second diagonal line in pairs; only a single third sub-pixel is arranged in each triangular area, and the single third sub-pixel, the second sub-pixel adjacent to the single third sub-pixel and the first sub-pixel located in the center of the virtual square form an acute triangle. Sub-pixel sharing is realized through the novel pixel arrangement structure so that sub-pixel distribution is enabled to be moreuniform, the space utilization rate can also be enhanced, and thus the difficulty of OLED panel process manufacturing can be reduced under the condition of meeting the technical requirement of high resolution.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel arrangement structure, a display panel using the pixel arrangement structure and a reticle set for manufacturing the pixel arrangement structure. Background technique [0002] At present, the active matrix organic light emitting diode (Active Matrix Organic Light Emitting Diode, referred to as AMOLED) display panel is called the next generation display technology. This display technology uses organic electroluminescence display and active matrix pixel addressing technology. Compared with the traditional liquid crystal display panels used in most current electronic devices, such as mobile phones and tablet computers, they have wider viewing angles, higher refresh rates and thinner sizes, so they are being widely used. [0003] In the top-emitting AMOLED panel preparation process, a high-precision metal mask (FMM for short) is often used to form an organic light-em...

AI Technical Summary

Problems solved by technology

Among them, the mask plate has a minimum opening limit, and the sub-pixels of different colors in the evaporation process have a limit on the opening pitch. Therefore, the preparation of AMOLED panels is inevitably limited by the mask plate opening and the precision of the evaporation process, and it is difficult to achieve high resolution.

[0004] In order to achieve high-resolution requirements, the prior art generally adopts the pixel arrangement method of sharing sub-pixels, but due to the limitation of the mask opening and the precision of the evaporation process, there is still a problem that it is difficult to achieve high-resolution requirements for AMOLED panels.
