Abstract

The invention provides a liquid crystal display, a display module thereof and a color light filtering device thereof, wherein the color light filtering device comprises a base plate, light filters and prism films; the light filters are attached onto the incident side of the base plate; the prism films are attached onto the light filters. Compared with the prior art, the liquid crystal display, the display module thereof and the color light filtering device thereof provided by the invention have the advantages that through the arrangement of two layers of prism films with different reflectivity rates at the incident side of the red light filter and the green light filter in the light filters and through the obtaining of the optimum prism saw tooth angle and the prism refractive index ratio by calculation, light in the blue and green wavelength bands in a light source can be reused; the utilization rate of a TFT (thin film transistor) display screen on the light is greatly improved; the energy saving goal is achieved. In addition, through improving the light utilization efficiency, the part of light adsorbed by the display module and converted into heat is reduced; the heat radiation pressure of the liquid crystal display is indirectly reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a liquid crystal display, a display module, and a color filter device. Background technique [0002] TFT (TFT: TFT (Thin Film Transistor) is the abbreviation of thin film transistor. TFT display screen is the mainstream display device on various notebook computers and desktop computers. Each liquid crystal pixel on this type of display screen is composed of The thin-film transistor behind the dot is used to drive it.) The display technology is a passive light-emitting display technology. The light from the backlight is transmitted through the TFT switch, and then the light is mixed through the red, green and blue color filters to form the desired color. Display in various colors as needed. The principle can be as figure 1 as shown, figure 1 It is a schematic structural diagram of a common liquid crystal display module in the prior art. [0003] When the existi...
