Liquid crystal panel taking laser as backlight

The invention discloses a liquid crystal panel taking laser as a backlight. The liquid crystal panel is characterized by comprising a plurality of laser light source modules, a plurality of light guide plates, a liquid crystal panel module, a mechanism framework and a plurality of optical films, wherein each laser light source module is arranged at one of four corners of an LCD TV panel and corresponds to one of the light guide plates; each light guide plate is provided with a plurality of polished surfaces; printing dots are arranged at the bottom of each light guide plate; the mechanism framework is fixedly arranged at the edge of the LCD TV panel and used for fixing the laser light source modules, the light guide plates, the liquid crystal panel module and the optical films. White-light laser is emitted from a plurality of positions on the side surfaces of the light guide plates through the LD laser light source modules, subjected to a series of diffuse reflection, total reflection, refraction and the like in the light guide plates and finally converted into a plane backlight required by both an LCD TV and a liquid crystal display panel, so that the production cost of the liquid crystal panel can be effectively lowered, and meanwhile, the color gamut of the liquid crystal panel can be greatly improved.
