Abstract

The embodiment of the invention provides a backlight module and a liquid crystal display device. The backlight module is arranged on the back face of the liquid crystal display screen and used for providing a backlight source for the liquid crystal display screen. The backlight module comprises a laser and an optical fiber. The laser is configured to generate laser with a specific wavelength, the optical fiber is provided with at least one light outlet, and the optical fiber is used for conducting the laser with the specific wavelength and enabling the laser with the specific wavelength to be scattered to the back face of the liquid crystal display screen through the light outlet. According to the embodiment, the laser with the specific wavelength is conducted and scattered to the back face of the liquid crystal display screen through the optical fiber with the light outlet, a traditional LED does not need to be used as a backlight source, the thickness of the display device is reduced, the spectrum monochromaticity of the laser is good, the half-peak width is narrow, and the color gamut of the display device is improved. The display effect of the display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a backlight module and a liquid crystal display device. Background technique [0002] In the traditional liquid crystal display industry, backlight modules require a large number of light-emitting diodes (LEDs). Especially in direct-lit products, the thickness of the module is limited by the light mixing distance of the LEDs, which seriously affects the thickness of the module. Moreover, the spectral monochromaticity of LED backlight is poor, and the half-peak width is relatively wide, which has great restrictions on high color gamut products. Contents of the invention [0003] In view of the shortcomings of the existing methods, the present application proposes a backlight module and a liquid crystal display device, which not only help to reduce the thickness of the backlight module, but also help to increase the color gamut of t...
