Color liquid crystal display module structure and backlight module thereof

Abstract

The invention provides a color liquid crystal display module structure and a backlight module thereof. The color liquid crystal display module structure comprises the backlight module (1) and a liquid crystal display panel (3). The liquid crystal display panel (3) comprises a CF substrate (33). The CF substrate (33) comprises a plurality of yellow light filter units (331) and a plurality of blue light filter units (333), wherein the yellow light filter units (331) and the blue light filter units (333) are arrayed alternately. The liquid crystal display panel (3) is provided with a plurality of pixels distributed in an array mode. Each pixel comprises two sub-pixels, wherein each sub-pixel corresponds to the corresponding yellow light filter unit (331) or the corresponding blue light filter unit (333). The backlight module (1) comprises an LED light source (13). The LED light source (13) comprises a plurality of first LED lamps (131) and a plurality of second LED lamps (133), wherein the first LED lamps (131) and the second LED lamps (133) are arrayed alternately. The first LED lamps (131) are packaged through blue light chips and green fluorescent powder. The second LED lamps (133) are packaged through blue light chips and red fluorescent powder. The first LED lamps (131) and the second LED lamps (133) are powered on alternately to form a first color field and a second color field respectively.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color liquid crystal display module structure and a backlight module thereof. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or laptop screen, etc. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal display panel disposed in the housing, and a backlight module disposed in the housing. [0004] see figure 1 , the current common liquid crystal display panel structure is composed of a color filter substrate (Color Filter, CF) 100, a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate) 200, and ...

AI Technical Summary

Problems solved by technology

However, in LEDs packaged with blue light chips and red and green phosphors, in addition to absorbing blue light to excite red light, red phosphors also absorb a small amount of green light, and the efficiency of green light to excite red light is very low, resulting in the blue light chip and The brightness of LEDs packaged with red and green phosphors is reduced
