Abstract

The invention discloses an organic light emitting display panel and a display device. An organic light-emitting display panel includes: a substrate; an organic light-emitting device on the substrate; a capping layer on the side of the organic light-emitting device away from the substrate, the capping layer includes scattering particles, and a scattering microstructure is arranged on the surface of the capping layer away from the organic light-emitting device. In the organic light emitting display panel and the display device provided by the present invention, the scattering particles and the scattering microstructures provided in the capping layer can realize the emission of light in all directions on the surface of the organic light emitting display panel through the joint action of the two structures, so that the organic light emitting display panel The scattered light can be seen from all angles, which improves the viewing angle deviation phenomenon. At the same time, the scattering particles can reduce the total reflection of light, reduce light loss, improve the light extraction rate, and then improve the luminous efficiency of OLED devices.

Description

technical field [0001] The present invention relates to the technical field of organic electroluminescence devices, and more particularly, to an organic light-emitting display panel and a display device. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diodes, OLEDs) use organic materials as semiconductor materials in light-emitting diodes, and these organic materials will emit light when an electric current passes through them. OLED display technology has the advantages of self-illumination, wide viewing angle, high contrast, low energy consumption, etc., and is widely used in smart products such as mobile phones, digital cameras, and notebook computers. And because of its light weight, thin thickness, and bending resistance, it is the research focus of many scholars at home and abroad. [0003] The light-emitting layer of the organic light-emitting display panel is an organic emitting layer (organic emitting layer, EML), and the organic ...
