High-color-gamut liquid crystal display module structure

Abstract

The invention provides a high-color-gamut liquid crystal display module structure. The high-color-gamut liquid crystal display module structure comprises a backlight module (1) and a liquid crystal display panel (3) arranged above the backlight module (1). The backlight module (1) comprises an LED light source (17) with the wavelength smaller than 460 nm. The liquid crystal display panel (3) comprises a TFT substrate (31), a CF substrate (33) arranged above the TFT substrate (31), a liquid crystal layer (35) arranged between the TFT substrate (31) and the CF substrate (33), and a fluorescent powder layer (5) arranged on the lower surface of the TFT substrate (31), the CF substrate (33) is provided with red, green and blue sub-pixel units arranged in an array mode, the fluorescent powder layer (5) comprises at least two of a red sub-pixel fluorescent powder unit (51), a green fluorescent powder unit (53) and a blue fluorescent powder unit (55) and is arranged corresponding to the red sub-pixel unit or the green sub-pixel unit or the blue sub-pixel unit. According to the structure, the color gamut of a liquid crystal display module can be effectively improved, and the liquid crystal display module has high color saturation.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a high color gamut liquid crystal display module structure. 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 panel disposed in the housing, and a backlight module disposed in the housing. [0004] The structure of the liquid crystal panel is composed of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged between t...

AI Technical Summary

Problems solved by technology

see figure 2 , when the light emitted by the white LED exits the CF through the backlight module, the obtained pure color point spectrum of the R, G, B three primary colors of the liquid crystal display module is not ideal. The spectral structure of the three primary colors has a tailing phenomenon, which results in widening of the half-peak width and reduction of color purity, corresponding to the shrinkage of the color point in the CIE diagram, which conflicts with the desired high color saturation
