Abstract

The invention provides a laser backlight module. The laser backlight module comprises an LED (Light Emitting Diode) lamp strip and a laser lamp strip on one side of the LED lamp strip, wherein the laser sources of the laser lamp strip are green light laser diodes; each LED lamp of the LED lamp strip comprises a base, a heat sink installed in the base, a blue light lamp wick fixed in the heat sink and a lamp shell, the base is fully filled with gel containing fluoride red light fluorescent powder, the gel covers the blue light lamp wick, the lamp shell covers the base and holds the gel, and the light sources of the laser lamp strip and the LED lamp strip are simultaneously lighted up as a backlight. The invention further provides a backlight module and a display device.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a laser backlight assembly, a backlight module and a display device. Background technique [0002] At present, liquid crystal display devices, as display components of electronic equipment, have been widely used in various electronic products. With the development of light and thin electronic products, the thickness of liquid crystal display devices is also getting smaller and smaller. The backlight module is an important part of the liquid crystal display device. [0003] In the prior art, with the development of LCD TVs in the direction of large size and high color saturation, in order to achieve better color saturation of the display and give people a rich visual experience, laser sources have been introduced into LCD as a backlight source in recent years. in the backlight of the display. In the current laser backlight, it is mainly blue chip + green phosphor LED (that ...
