Organic light emitting diode display pixel arrangement structure and display device

Abstract

The invention discloses a pixel arrangement structure of an organic light emitting diode display and a display device. The pixel arrangement structure includes a plurality of closely arranged first pixels and / or second pixels, and each first pixel and second pixel has the same size. Each of the first pixel and the second pixel includes a first sub-pixel, a second sub-pixel arranged at two ends of a diagonal of the rectangle, and a third sub-pixel arranged along the other diagonal of the rectangle. The invention improves the aperture ratio of the pixel, makes the arrangement structure of the first sub-pixel, the second sub-pixel and the third sub-pixel more compact, and the display color is more uniform, breaks through the limitations of the FMM manufacturing process and coating process, and effectively improves the OLED display. The PPI value and resolution improve the image quality and effect of OLED display.

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
