Abstract

The invention discloses a straight-down-type backlight, a module group and a laser television. The straight-down-type backlight includes a shell, an RGB laser emitter, and a reflective component. Theshell includes a first panel provided with the RGB laser emitter and a second panel connected to the first panel. The second panel is provided with a light emitting hole. The RGB laser emitter is capable of emitting a first collimated light beam to the reflective component. The reflective component includes a diffuse reflector capable of reflecting the first collimated light beam into a diffuse reflection light beam to the light emitting hole of the second panel. Or the reflective component includes a plane mirror and a concave lens, the plane mirror can reflect the first collimated light beaminto a second collimated light beam to the concave lens, and the concave lens can refract the second collimated light beam into a diffusion light beam to the light emitting hole. The invention aims at solving the technical problems of the insufficient brightness, color gamut and contrast of an existing television liquid crystal module group.

Description

technical field [0001] The invention relates to the field of backlight modules, in particular to a direct-lit backlight source, a module and a laser TV. Background technique [0002] With the upgrading of market demand, while the appearance of TV sets is being upgraded, the content is also constantly being upgraded. In order to display rich content resources more realistically and completely, it is necessary to improve the intrinsic display quality of the TV. As for display quality, indicators such as brightness, color gamut, and contrast of the LCD module are all parts that need to be improved and broken through. For high brightness and high contrast, it is currently achieved by increasing the number of LEDs and LOCAL DIMMING (regional dimming). Ultra-thin models on the market are all edge-lit products, and the number of LEDs directly conflicts with heat dissipation. LOCAL The trend of DIMMING is not very high, so the brightness is not very high. [0003] The way to real...
