Abstract

The invention provides a quantum dot liquid crystal display device, which comprises a quantum dot liquid crystal display panel and a backlight module. The quantum dot liquid crystal display panel comprises a color film substrate and an array substrate and a liquid crystal layer arranged between the color film substrate and the array substrate. The color film substrate comprises a first substrate, a color film layer and an upper polarizer, wherein the color film layer comprises a plurality of transparent color film units and a mixed color film unit arranged in a matrix, and the backlight module includes a blue backlight light source and a red backlight light source, among which the backlight module alternately circulates the blue backlight light source and the red backlight light source according to preset timing driving rules. The invention effectively reduces the Cd content of the quantum dot liquid crystal display device, achieves the goal of the quantum dot liquid crystal display device satisfying the high color gamut coverage, and also greatly enhances the light output rate of the quantum dot liquid crystal display panel.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of flat panel display technology, in particular to a quantum dot liquid crystal display device. [0003] 【Background technique】 [0004] Quantum Dots are extremely small semiconductor nanocrystals that cannot be seen by the naked eye, and are particles with a particle size of less than 10 nanometers. Generally speaking, quantum dots are composed of zinc, cadmium, selenium and sulfur atoms. Quantum dots have a unique characteristic, that is, whenever stimulated by light or electricity, quantum dots will emit colored light, and the color of light is determined by the composition material and size and shape of quantum dots. This characteristic enables quantum dots to change The color of the light emitted by the light source. As a new type of luminescent material, quantum dots have the advantages of high light color purity, high luminous quantum efficiency, adjustable luminous color, and long service life, and h...
