Abstract
The present invention provides a structure of a high color gamut liquid crystal display module, which includes a backlight module () and a liquid crystal display panel () arranged above the backlight module (). The backlight module () includes an LED light source () and the LED light source () is an LED light source having a wavelength below 460 nm. The liquid crystal display panel () includes a TFT substrate (), a CF substrate () arranged above the TFT substrate (), a liquid crystal layer () arranged between the TFT substrate () and the CF substrate (), and a fluorescent powder layer () arranged on a lower surface of the TFT substrate (). The CF substrate () includes red, green, and blue sub-pixel units that are arranged in a matrix. The fluorescent powder layer () includes at least two of red, green, and blue fluorescent powder units (), which are arranged to respectively correspond to the blue, green, or blue sub-pixel units. The structure effectively increases color gamut of a liquid crystal display module and provides the liquid crystal display module with high color saturation.
