Organic light-emitting diode display panel and display device

Abstract

The invention provides an organic light-emitting diode display panel and a display device and relates to the technical field of organic electronic devices. Compared with a pixel arrangement mode adopted by an organic light-emitting diode display panel in the prior art, the service life of an OLED displayer can be prolonged. The organic light-emitting diode display panel comprises multiple pixel units. Each pixel unit at least comprises red, green and blue sub-pixels formed by different organic electroluminescence materials; each pixel unit at least comprises three areas, the number of the areas is the same as the number of the sub-pixels of the pixel units, and areas of all the areas are the same; the blue sub-pixels are located in at least two areas of each pixel unit, other sub-pixels of different primary colors are located in different areas respectively, and the area of the blue sub-pixels is greater than that of other sub-pixels of the same primary color. The organic light-emitting diode display panel and the display device are used for manufacturing of organic light-emitting diode display panels and display panels comprising the organic light-emitting diode display panels.

Description

technical field [0001] The invention relates to the technical field of organic electronic devices, in particular to an organic light emitting diode display panel and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays have been widely used in the field of display technology. The basic structure of an OLED display includes an anode, a light-emitting layer and a cathode, wherein the light-emitting layer is formed using an organic electroluminescence material. [0003] The OLED display has the characteristic of self-luminescence, that is, when a current passes through the light-emitting layer, the organic electroluminescent material will emit light, and different materials can emit light of different colors. However, a single display color obviously cannot satisfy the public's pursuit of full-color high-quality images. OLED displays realize color display based on the principle of three primary colors. The ...

Problems solved by technology

[0005] However, limited by the development of organic electroluminescent materials, the performance and lifespan of organic electroluminescent materials that can emit blue light are far lower than those that can emit red and green light.

Due to the poor performance of the light-emitting layer material corresponding to the B sub-pixel, it needs to pass a large current to emit the brightness of the light to be displayed, and the light-emitting time of the light-emitting layer material is related to the magnitude of the current passing through it. The greater the current, the more light will be emitted. The shorter the light-emitting time of the layer material, in this way, if the three sub-pixels of R, G, and B are still arranged in the above-mentioned way, when the life of the light-emitting layer material corresponding to the B sub-pixel is over, that is, the B sub-pixel no longer emits light, then only by The R and G sub-pixels cannot display all colors, which reduces the service life of the OLED display
