OLED display panel and OLED display device

Abstract

The invention provides an OLED display panel and an OLED display device. The OLED display panel comprises a substrate, a driving circuit layer and a light emitting layer, wherein the driving circuit layer is arranged on one side of the substrate, the light emitting layer is arranged on the side, away from the substrate, of the driving circuit layer, the light emitting layer comprises a plurality of light emitting pixels, and the distances between a plurality of light emitting sub-pixels of at least one color of at least one light emitting pixel are not equal. The distances between the multiple light emitting sub-pixels of at least one color of at least one light emitting pixel are set to be unequal, so that the multiple light emitting sub-pixels of at least one color of at least one light emitting pixel are not periodically distributed, and when external light with the same frequency passes through the multiple light emitting sub-pixels, due to the fact that the periods of the light emitting sub-pixels are different, coherent interference of reflected light rays is avoided, and the color separation phenomenon of the display panel caused by interference of the reflected light rays is improved.

Description

technical field

[0001] The present application relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique

[0002] With the development of display technology towards thinner, more flexible, and wider viewing angles, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display devices have the advantages of no backlight, flexibility, wide viewing angle, ultra-high contrast, and response speed. Fast and other advantages are widely used. In order to reduce the power consumption of OLED display devices and improve the luminous efficiency of OLED display devices, color resistance will be used to replace polarizers, that is, Polless (no polarizer) technology, but because OLED display devices do not have polarizers, it will cause point light sources to illuminate OLEDs. When the surface of the display device is displayed, interference occurs when the light is reflected, resulting in color separat...
