Organic light emitting diode display pixel array structure and display device

Abstract

The invention discloses an organic light emitting diode display pixel array structure and a display device. The pixel array structure comprises a plurality of first pixels and / or second pixels arrayed tightly; the first pixels and the second pixels are rectangles of the same size; each first pixel as well as each second pixel comprises a first sub-pixel and a second sub-pixel which are arranged at the two ends of one diagonal line of the corresponding rectangle, and a third sub-pixel arranged on the other diagonal line. According to the invention, the pixel aperture ratio is improved; the array structure of the first sub-pixels, the second sub-pixels and the third sub-pixels is tighter; color is displayed more uniformly; the limitation of an FMM manufacture process and a coating technology is broken through; OLED display PPI value and resolution are efficiently improved; the OLED displayed image quality and effect are improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, in particular to an organic light emitting diode display pixel arrangement structure and a display device. Background technique [0002] In recent years, organic light-emitting diodes (Organic Light-Emitting Diode, OLED) have self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, and use temperature range Wide, simple structure and manufacturing process and other excellent characteristics, it is considered to be the new application technology of the next generation flat panel display. Organic light-emitting display technology consists of very thin coatings of organic materials and glass substrates that emit light when an electric charge passes through them. Compared with LCD displays, OLED has the advantages of saving power, being thinner, and having a wider viewing angle, which is unm...

Problems solved by technology

However, the existing RGB pixel arrangement structure is difficult to meet the high-resolution and high-brightness requirements of electronic devices for display screens. In the case of achieving the same resolution; another existing OLED pixel arrangement structure is to share However, the ratio of R / G / B of the pixels formed by this arrangement is 1: 1: 2, which will affect the display effect of the display. It will be more complicated in the OLED manufacturing process, and it is not conducive to the development of organic materials. Evaporation, easy to mix colors
