Abstract

The invention relates to a light source assembly and a liquid crystal display device. A graphene LED (light emitting diode) chip is provided with a plurality of adjustable wavelength points, an LED white light source is formed by mixing a plurality of base color lights with fixed wavelength, and a first LED base color light source is provided with a first wavelength point, so that a display color gamut can be expanded by the multiple adjustable wavelength points of the graphene LED chip and the first wavelength point; the structure of the display color gamut comprises a radial color supplementing area which is formed from a coverable color gamut range of the LED white light source, multiple adjustable wavelength points of the graphene LED chip and the first wavelength point of the first LED base color light source, and the color supplementing area and the coverable color gamut of the original LED white light source can form the color gamut display area.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a light source assembly and a liquid crystal display device. Background technique [0002] A liquid crystal display device is composed of a liquid crystal panel, a mechanism frame, optical components, and some circuit boards. Since the liquid crystal itself does not emit light, some backlight sources need to be configured to display the picture. Wherein, the backlight module is used to provide a backlight with uniform brightness and distribution for the liquid crystal display device, so that the liquid crystal display device can display images normally. [0003] Wherein, the backlight module provides a white source to display a color picture through the control of three-color pixels in the liquid crystal panel. The white backlight is formed by mixing the three primary colors of red, green, and blue. According to the principle of color mixing, the area of ​​the t...
