Abstract

The invention relates to the technical field of liquid crystal display, in particular to quantum dot and YAG fluorescent powder doped liquid crystal display equipment. A light source structure is composed of a solid cooling aluminum shell (1), a PCB (2), a blue light LED (3) and a quantum dot film (4). The solid cooling aluminum shell (1) is in a strip-shaped groove shape, the blue light LED (3) is installed at the groove-shaped bottom of the solid cooling aluminum shell through the PCB (2), light-transmitting glass (12) is arranged on a notch of the solid cooling aluminum shell (1), the quantum dot film (4) is laid on a light entry of a light guide plate (5), and quantum dots and yellow fluorescent powder are distributed in the quantum dot film (4). The color gamut width is increased and can reach 110%; in addition, the quantum dot film is arranged on a reflecting plate, the quantum dot film and the light source structure are two parts, heat dissipated by the light source structure can be effectively isolated, and the instability, caused by the temperature change, of the quantum dots is further reduced.

Description

technical field

[0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device in which quantum dots and YAG fluorescent powder are mixed. Background technique

[0002] Quantum dots are quasi-zero-dimensional nanomaterials composed of a small number of atoms. Roughly speaking, the three dimensions of quantum dots are all below 100 nanometers (nm). confinement effect) is particularly remarkable.

[0003] The color gamut of an LCD TV depends on the spectral characteristics of the backlight and how well the spectrum matches the color filter (CF) of the LCD panel. The backlight source only needs white light, and the white light can get any desired color through a filter. If the white light color gamut is high enough, the LCD TV color gamut will also be high. At present, the industry generally adopts the NTSC color gamut standard to measure the color display effect. The higher the color gamut coverage (referred t...
