Abstract

The invention provides an OLED display backboard, a manufacturing method thereof and an OLED display device. The OLED display backboard comprises a substrate base plate which is provided with a firstsurface; a plurality of pixel units are arranged on the first surface, and each pixel unit comprises a reflection anode; a first color light-emitting functional layer is arranged on the surface, far away from the substrate, of the reflecting anode; a first transparent cathode which is arranged on the surface of the first color light-emitting function layer, and the orthographic projection of the first transparent cathode on the substrate only covers the orthographic projection of the first color sub-pixel on the substrate; a semi-transparent semi-reflective cathode which is arranged on one side, far away from the substrate, of the first color light-emitting functional layer, and the orthographic projection of the semi-transparent semi-reflective cathode on the substrate is not overlapped with the orthographic projection of the first color sub-pixel on the substrate; and a second color quantum dot color film and a third color quantum dot color film. The display backboard is high in light efficiency, free of visual angle color cast, low in pixel current and low in power consumption.

Description

technical field [0001] The invention relates to the field of display technology, in particular, to an OLED display backplane, a manufacturing method thereof, and an OLED display device. Background technique [0002] Quantum dot display is an innovative semiconductor nanocrystal technology, which can accurately transmit light, efficiently improve the color gamut of the display, make the color more pure and vivid, and make the color performance more tense, so it is deeply loved by the majority of users. However, large-size quantum dot (QD) OLED display panels usually have technical problems such as angular deviation, low light efficiency, or high power consumption. [0003] Therefore, the research on the quantum dot OLED display backplane needs to be in-depth. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide an OLE...
