Problems solved by technology

Red quantum dots can absorb the green light emitted by green quantum dots, and then emit red fluorescence by themselves. This process leads to a decrease in the intensity of green light, which affects the light efficiency of the backlight module and the display effect of the display device.
If the green light intensity is increased by increasing the amount of green quantum dots, the red light will be enhanced at the same time, which also makes it difficult to adjust the backlight from the point

Abstract

The invention provides a backlight module and a display device, the backlight module is characterized by comprising a back light, a light guide plate, a red light quantum dot layer and a green light quantum dot layer, wherein the back light is used for emitting blue light, the light guide plate comprises a light-in surface and a light-out surface, the red light quantum dot layer and the green light quantum dot layer are arranged on the light-in surface and the light-out surface respectively, and the light emitted by the back light passes by the red light quantum dot layer, the light guide plate and the green light quantum dot layer sequentially and is emitted. According to the backlight module and the display device, the light effect of the backlight module and the display effect of the display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] Quantum dots are nanocrystals composed of several atoms. When the quantum dot material is stimulated by electricity or light, it will emit strong fluorescence, and the half-maximum width of the fluorescence emission peak is extremely narrow, and the color purity is high. Therefore, if self-luminescent quantum dots are used to replace traditional RGB pigments in color photoresist materials, the brightness and color expressiveness of the display screen can be greatly improved, and energy consumption can also be reduced. [0003] In the process of using quantum dot materials, there will be great disadvantages in using a fluorescent film containing both red quantum dots and green quantum dots. The red quantum dots can absorb the green light emitted by the green quantum dots, and then emit red fluorescence by the...
