Problems solved by technology

In the process of making this traditional display structure, in order to avoid color mixing between adjacent sub-pixels, the distance between two adjacent sub-pixels is often increased, but this will affect the resolution and reduce the organic light-emitting display (OLED). Organic light emitting diode, abbreviated as OLED) service life

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 each pixel comprises a first subpixel unit, a second subpixel unit and a third subpixel unit, which are arranged in sequence; the first subpixel unit is provided with a plurality of red subpixels; the second subpixel unit is provided with a plurality of green subpixels; and the third subpixel unit is provided with a plurality of blue subpixels. The pixel structure has the following advantages: by adopting the pixel structure, the resolution and aperture ratio of the OLED can be increased and the life of the OLED can not be affected.

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 and power saving. It has become the mainstream flat-panel display, so it is considered as a new A 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 sub-pixels are arrang...
