Abstract

Embodiments of the present invention provide an OLED substrate, a manufacturing method thereof, and a display device, which relate to the field of display technology and can improve uniformity of light emission. An OLED substrate, comprising: a substrate, an OLED device arranged in a sub-pixel region on the substrate, the thickness of the middle region of the organic layer of the OLED device is different from that of the edge region; The transmittance adjustment layer in the sub-pixel area on the substrate and located on the light-emitting side of the organic layer, the transmittance of the transmittance adjustment layer corresponding to the thicker region of the organic layer is greater than that corresponding to the thickness of the organic layer Transmittance in thinner regions.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED substrate, a preparation method thereof, and a display device. Background technique [0002] Compared with Liquid Crystal Display (LCD), Organic Light-Emitting Diode (OLED) display has the advantages of self-illumination, fast response, wide viewing angle, high brightness, bright color, light and thin, etc. A generation of display technology. [0003] The organic layer preparation methods of each sub-pixel in an OLED display mainly include vacuum evaporation and solution processing. Vacuum evaporation is suitable for small organic molecules. The film formation is uniform and the technology is relatively mature, but the investment in equipment is large, the utilization rate of materials is low, and the alignment accuracy of large-size products is low. Solution process, including spin coating, inkjet printing, nozzle coating method, etc., is suitable for polymer material...
