Abstract

The invention discloses a liquid crystal display screen, a display device and a quantum dot layer graphical method. A plurality of pixel units are arranged in a liquid crystal panel; each pixel unit comprises a plurality of subpixel units capable of displaying different colors; and a monochromatic quantum dot layer is arranged at the position corresponding to at least one color of subpixel unit of each pixel unit. The embodiment of the invention substitutes the quantum dot layer for the conventional resin to serve as a color filter for converting background light into monochromatic light, the emission spectrum of the quantum dots is narrow and the luminous efficiency is high, and the background light can be efficiently converted into monochromic light, so the color gamut of the liquid crystal display screen can be improved, the color saturation is enhanced and the display quality of the display screen is improved. The monochromic quantum dots are dispersed by a high-molecular polymer network, so accumulation of the quantum dots can be avoided, the quantum yield is increased, the quantum excited lighting effect can be improved, contact of the monochromic quantum dots and oxygen can be avoided, and the service life of the quantum dots is prolonged.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display screen, a display device and a method for patterning a quantum dot layer. Background technique [0002] Quantum Dots (QDs), also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between 1 and 20 nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure with molecular characteristics, and can emit fluorescence after being excited. [0003] The emission spectrum of quantum dots can be controlled by changing the size of quantum dots. By changing the size of the quantum dot and its chemical composition, its emission spectrum can cover the entire visible light region. Taking CdTe quantum dots as an example, when its particle size grows from 2.5nm to 4.0nm, their emission wavelength can be red-shif...
