Problems solved by technology

[0003] At present, for the color gamut specification of DCI-P3, high-order DCI-P3 can reach 99% through quantum dot technology, but the cost of quantum dot technology remains high
Moreover, the heavy metal cadmium used in quantum dot technology also limits its widespread use
The general KSF backlight can make DCI-P3 up to 95% at present, and it is still difficult to reach the high-end DCI-P3 color gamut specification

Abstract

The invention provides a backlight module, a preparation method thereof, and a liquid crystal display device. The backlight module comprises a back plate, a light source and a light conversion coating. The back plate is provided with a containing cavity and a fixing component. The light source is arranged in the containing cavity and is fixed by the fixing component. the light source is coated with the light conversion coating. The light conversion coating comprises fluorescent powder and a light absorption factor, and the light absorption factor is used for absorbing light of a specific frequency band. Therefore, the color gamut of KSF backlight is further improved.

Description

technical field [0001] The disclosure relates to the field of display technology, in particular to a backlight module, a manufacturing method thereof, and a liquid crystal display device. Background technique [0002] The development process of display technology is also the pursuit of color reproduction capabilities. From the first-generation color gamut specification sRGB to DCI-P3, to the next-generation BT.2020, the color gamut is improving. A high color gamut means that the TV can display more colorful colors and has stronger color display capabilities, which can effectively avoid distortion and color blocks during display. The color gamut specification of DCI-P3 is regarded as the next-generation color gamut specification to replace sRGB. It is a color gamut applied to digital theaters. It is a color gamut standard dominated by human visual experience and matches movie scenes as much as possible. The full color gamut that can be displayed in . Compared with sRGB, it ...
