Abstract

The invention provides a backlight module and a display device, the backlight module comprises a light source assembly, a quantum dot assembly and a wave band light reflection assembly which are arranged in a stacked mode, and the wave band light reflection assembly can reflect light in a specific wave band range in light emitted by the quantum dot assembly so as to reduce the full width at half maximum of the light; the smaller the full width at half maximum of the light is, the purer the monochromatic light is, and the more the number of the color light which can be displayed by the display module is, namely the higher the color gamut of the display module is. By arranging the waveband light reflection assembly for reflecting the light in the specific waveband range, the full width at half maximum of the monochromatic light is reduced, and then the color gamut of the display module is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a backlight module and a display device. Background technique [0002] As an important indicator for measuring the color performance of liquid crystal display products, color gamut has attracted more and more attention from ordinary consumers and manufacturers. In order to improve the color gamut of liquid crystal display products, major manufacturers can be said to come up with their own ideas. [0003] Because the current mainstream high-end liquid crystal display products all use blue light emitting diode (Light Emitting Diode, LED) + quantum dot film (Quantum Dots, QD) backlight to improve the color gamut of display products, but due to the limitation of quantum dot materials, the light The half-height width cannot be made narrower, and the color gamut of LCD display products cannot be made higher. SUMMARY OF THE INVENTION [0004] The present application ...
