Reflector plate and preparation method thereof, backlight module and display device

Abstract

The present invention discloses a reflector plate and a preparation method thereof, a backlight module and a display device, and relates to the display technology field. The objective of the invention is to solve the problems that the color gamut breadth of the backlight module is small and the color gamut expressive ability of the display device is bad caused by wide half-wave width of the light required in the backlight provided by the background module. The reflector plate comprises a reflection substrate and at least one color dye doped in the reflection substrate, wherein the color of at least one dye and the color of the light, which is not required, in the light to be incident on the reflection plate are complementary colors. The reflection plate is arranged in the backlight module, the dye in the reflection plate can absorb the light, which is not required, in the light emitted by the light source of the backlight module to allow the half-wave width of the spectrum of the light required in the spectrum of the backlight provided by the backlight module to be narrow, add the color gamut breadth of the backlight provided by the backlight module and improve the color gamut expressive ability of the display device. The reflection plate provided by the invention is applied into the backlight module, and the backlight module is configured to provide backlight for the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a reflection sheet and a preparation method thereof, a backlight module and a display device. Background technique [0002] The function of the display device is to reproduce the color. In the color reproduction technology, the color of the image can be reproduced by using the graphics processing technology, and whether the color can be fully presented depends on the color gamut of the display device. expressiveness. The color gamut is a subset of colors. The most common application of color subsets is to accurately represent the real color in a specific environment, such as a color space (color space) or an output device (such as a display device) Color range. [0003] In the prior art, there is a display device including a backlight module and a display panel located on the light output side of the backlight module. The backlight module provides backlight for the display pan...
