Abstract

The invention discloses a quantum-dot light-emitting diode displayer and a display device. Electroluminescence structures are arranged in subpixel units of pixel units; a monochromatic quantum dot layer is arranged in the subpixel unit of at least one color of each pixel unit and positioned on light emerging sides of the electroluminescence structures; the monochromatic quantum dot layers emit monochromatic light corresponding to the colors of the subpixel units after excited by light emitted by the electroluminescence structures. Quantum dots are adopted to replace the existing inorganic doping system as a photochromic conversion material; the quantum dots can emit the monochromatic light after excited by the light emitted by the electroluminescence structures; since the quantum dots are narrow in emission spectrum and high in luminous efficiency, the color purity of the subpixel units forming the pixel units can be improved, and the display quality of the displayer is improved. In addition, since the quantum dots can scatter the light emitted by the electroluminescence structure, the light transmittance of photochromic conversion can be improved in comparison with the inorganic doping system material, and the luminous efficiency of the displayer is improved.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a quantum dot light-emitting diode display device and a display device. Background technique [0002] Organic light-emitting diode (OLED) displays have been more and more used in flat panel displays in recent years due to their advantages such as thinness, wide viewing angle, fast response speed, and high contrast ratio. The use of blue-emitting OLEDs combined with color conversion (Color Conversion) materials is one of the technologies to realize full-color OLEDs. The currently used light-color conversion materials are mainly inorganic doping system materials that can be excited by blue light: ① Ce-doped yttrium aluminum Garnet; ②Eu-doped alkaline earth metal silicate; ③Si-based nitride or nitrogen oxide doped with rare earth ions. However, these light-color conversion materials usually have problems of low color purity and low efficiency. [0003] Quantum Dots (QD...
