Abstract

A quantum dot light emitting diode display provided by the present invention comprises a first electrode, a cavity injection layer, a cavity transmission layer, a quantum dot light emitting layer, an electronic transmission layer and a second electrode which are formed on a substrate orderly, the quantum dot light emitting layer comprises a plurality of pixel units, and each pixel unit comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel, wherein the at least one color of the sub-pixel of the red sub-pixel, the green sub-pixel and the blue sub-pixel is formed by mixing the quantum dots of at least two corresponding colors having different light emitting peak value wavelengths. The at least one color of the sub-pixel in the pixel units is formed by mixing the quanta of the at least two corresponding colors, so that the quantum dot light emitting diode display of the present invention enables the light rays to be softer and the display effect to be improved.

Description

【Technical Field】 [0001] The present invention relates to the technical field of displays, in particular to a quantum dot light emitting diode display. 【Background technique】 [0002] Quantum Dots Light Emitting Diodes (QD-LEDs) displays, a single sub-pixel in the pixel unit is formed by a kind of quantum dot, for example, the red sub-pixel is composed of a single red light quantum dot, and the green sub-pixel is composed of a single quantum dot. The green light quantum dots and the blue sub-pixels are composed of a single blue light quantum dot, which can improve the brightness and vividness of the picture while reducing energy consumption, thus becoming the main research direction of displays. Compared with Organic Light Emitting Diodes (OLEDs), QD-LEDs have many advantages: quantum dot light-emitting diodes have a narrower half-value width, higher color purity of the screen, longer service life, and higher external quantum Efficiency, its external quantum efficiency (EQE) may...
