Abstract

The invention provides a pixel arrangement structure, a metal mask plate and an organic light-emitting display device. The pixel arrangement structure comprises a plurality of pixel units arranged in an array in sequence, wherein each pixel unit comprises a first sub-pixel, a second sub-pixel and two third sub-pixels with the same area, the two third sub-pixels with the same area are arranged in the same row, the first sub-pixels and the second sub-pixels are arranged in the other adjacent row, and the two third sub-pixels with the same area and at least one adjacent third sub-pixel correspond to the same opening area of a metal mask plate. According to the pixel arrangement structure, the metal mask plate and the organic light-emitting display device, the sub-pixels can share the opening area by splitting the sub-pixels and adjusting the distribution positions of the sub-pixels, so that the display brightness of the organic light-emitting display device is improved, the service life of the organic light-emitting display device is prolonged, and poor display such as sawteeth, black lines and the like is effectively improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a pixel arrangement structure, a metal mask plate and an organic light-emitting display device. Background technique [0002] Compared with many display devices, Organic Light Emitting Display (OLED) has the advantages of all solid state, self-illumination, wide viewing angle, wide color gamut, fast response, high luminous efficiency, high brightness, high contrast, ultra-thin Ultra-light, low power consumption, wide operating temperature range, large-size and flexible panels and simple manufacturing process, etc., can realize flexible displays in the true sense, which can best meet people's requirements for future displays. [0003] In the manufacturing process of OLED, a fine metal mask (FMM) is usually used to prepare red, green, and blue light-emitting layers to form red (R), green (G), blue (B) sub-pixels, and RGB three sub-pixels. Pixels are arranged repeatedly ...
