Pixel structure of organic light emitting diode (OLED)

Abstract

The invention provides a pixel structure of an organic light emitting diode (OLED). The pixel structure is arranged on a substrate and comprises a plurality of pixels, wherein the pixels are arranged in a matrix in the X-axis and Y-axis directions; each pixel comprises a first subpixel, two second subpixels and a third subpixel; the first subpixel, one second subpixel, the third subpixel and the other second subpixel are arranged in sequence in the X-axis direction; the first subpixel comprises two first light emitting zones; each second subpixel comprises a second light emitting zone; the third subpixel comprises two third light emitting zones; and the adjacent first light emitting zone, second light emitting zone and third light emitting zone are arranged in a triangle, the geometric centers of the three light emitting zones are arranged on different peaks of the triangle, and one side of the triangle formed by connecting the geometric centers of the first light emitting zone and the third light emitting zone, is parallel to the X-axis. The pixel structure has the following advantages: by adopting the pixel structure, color mixture can be avoided, the resolution can be increased and the aperture ratio can be increased and the service life can be prolonged.

Description

technical field [0001] The present invention relates to a pixel structure, in particular to a pixel structure of an organic light emitting display. Background technique [0002] Organic light-emitting display (organic light emitting diode, abbreviated as OLED) has a large viewing angle, excellent contrast and high response speed, and has the characteristics of thinness, power saving, high resolution, etc., and has become the mainstream flat panel display. It is considered to be a new generation of displays. [0003] The color image of an organic light emitting display (OLED for short) is mainly provided by a plurality of pixels, and these pixels have three sub-pixels of red, green and blue. The design of the pixel structure affects the resolution of an organic light emitting diode (OLED for short). In the prior art, in the display structure of an organic light-emitting display (abbreviated as OLED), each pixel has three sub-pixels of red, green and blue, and these three su...

AI Technical Summary

Problems solved by technology

The smaller the spacing between adjacent sub-pixels, the higher the resolution of the display panel, but it is easy to produce alignment errors during the manufacturing process, which will cause the color organic layer in the sub-pixel to be deposited into the adjacent sub-pixel, resulting in sub-pixel Color mixing occurs in the light emitted by the pixels

The arrangement of the sub-pixels will also make the corresponding mask encounter considerable difficulties in etching. Therefore, it is difficult to manufacture a high-resolution organic light-emitting display (abbreviated as OLED) using the existing sub-pixel arrangement.
