Abstract

The invention discloses a cover plate, an organic light-emitting display panel and a display device. Specifically, the present invention provides the cover plate for the organic light emitting displaydevice, and the cover plate comprises a substrate having a plurality of light emitting units defined by a light shielding structure and having a light incident surface and a light emitting surface, wherein a color conversion layer is arranged in at least part of the light emitting units and is arranged on the light incident surface of the substrate; a light modulation layer which is arranged at the side, away from the substrate, of the color conversion layer, and is configured to enable incident light to penetrate through the color conversion layer and the substrate and to be emitted out fromthe light emitting surface of the substrate. Therefore, the light modulation layer can adjust the light emitting direction of the incident light, the incident light can be emitted from the light emitting surface, the light emitting efficiency of the organic light emitting display panel can be improved, the power consumption can be reduced, and the display quality can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a cover plate, an organic light-emitting display panel, and a display device. Background technique [0002] Organic electroluminescence (OLED) display technology is characterized by self-illumination, wide viewing angle, high contrast ratio, low power consumption, extremely high response speed, ultra-thin weight, flexible display, rollable screen, strong temperature adaptability, and simple manufacturing process, etc. Advantages, has become a research hotspot in the field of optoelectronic display technology. When existing OLED devices realize full-color display, some methods use fine metal masks to separately prepare a light-emitting layer that can emit red light, a light-emitting layer that can emit green light, and a light-emitting layer that can emit blue light. The process of this method is relatively complicated. , high process precision is required, and it is dif...
