Abstract

The invention relates to the technical field of display, which discloses a quantum dot color filter, a liquid crystal panel and a display device. The quantum dot color filter is used for the liquid crystal panel. The liquid crystal panel is provided with a plurality of pixels, wherein each pixel is provided with a plurality of sub-pixels. Each sub-pixel corresponds to a color. The color filter comprises sub-areas in one-to-one correspondence to the sub-pixels. At least one sub-area is formed by quantum dot materials. Light generated by the quantum dot materials activated is as same as the corresponding sub-pixel in color. According to the invention, the color filter of a display is formed by the quantum dot materials, and a red, or green, or blue filter is made of quantum dot materials which generate red, or green, or blue light through photoexcitation, so that the utilization ratio of a backlight source is improved, and meanwhile, colored light with higher purity can be obtained. Therefore, the quantum dot display can realize high color gamut and low power consumption of color display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot color filter, a liquid crystal panel and a display device. Background technique [0002] Quantum Dot (Quantum Dot) is a semiconductor nanostructure that binds conduction band electrons, valence band holes, and excitons in three spatial directions. This constraint can be attributed to electrostatic potential (by external electrodes, doping, strain, impurity generation), the interface of two different semiconductor materials (e.g. in self-assembled quantum dots), the surface of a semiconductor (e.g. semiconductor nanocrystals), or a combination of all three. Quantum dots have separate quantized energy spectra, corresponding to wave functions that are spatially located in the quantum dot, but extend over several lattice periods. A quantum dot has a small number (1-100) of an integer number of electrons, holes or hole-electron pairs, that is, the charge it carries is ...
