Abstract

The embodiment of the invention discloses an OLED device and a display device. The OLED device comprises a substrate, an anode, a hole injection layer, a hole transport layer, a light emitting layer,an electron transport layer, an electron injection layer and a cathode, wherein the light emitting layer comprises a light emitting main body material and a quantum dot material; the light emitting main body material comprises a phosphorescent material emitting green light and emitting red light, and a fluorescent material emitting blue light. Through doping the quantum dot material to the organiclight emitting main body material as a light emitting layer to build the OLED device, the problems that red and green phosphorescent organic materials in OLED devices have too high price and the efficiency of the blue fluorescent material is insufficient is solved, and the light emitting efficiency of the OLED device is finally improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED device and a display device. Background technique [0002] Today's flat panel display devices mainly include liquid crystal display devices (Liquid Crystal Display, LCD) and organic electroluminescent display devices (Organic Light Emitting Display, OLED). OLED is considered to be the most advanced technology due to its self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panel, wide operating temperature range, and simple structure and manufacturing process. Next-generation flat-panel display emerging application technology. [0003] The structure of the OLED device in the prior art includes a substrate, a transparent anode placed on the substrate, a hole injection layer placed on the transparent anode, a hole transport layer placed on the hole injection layer, and a hole transport layer placed on th...
