The present invention provides a structure of a high color gamut liquid crystal display module, which includes a backlight module (1) and a liquid crystal display panel (3) arranged above the backlight module (1). The backlight module (1) includes an LED light source (17) and the LED light source (17) is an LED light source having a wavelength below 460 nm. The liquid crystal display panel (3) includes 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 a lower surface of the TFT substrate (31). The CF substrate (33) includes red, green, and blue sub-pixel units that are arranged in a matrix. The fluorescent powder layer (5) includes at least two of red, green, and blue fluorescent powder units (51, 53, 55), 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. |

1. A structure of a high color gamut liquid crystal display module, comprising a backlight module and a liquid crystal display panel arranged above the backlight module, the backlight module comprising a light-emitting diode (LED) light source, the LED light source being an LED light source having a wavelength below 460nm, the liquid crystal display panel comprising a thin-film transistor (TFT) substrate, a color filter (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 comprising red, green, and blue sub-pixel units arranged in a matrix;
wherein the red, green, and blue sub-pixel units respectively comprise red, green, and blue color resist units, and the fluorescent powder layer comprises red, green, and blue fluorescent powder units that are mounted on the TFT substrate to respectively correspond to the red, green, and blue color resist units mounted on the CF substrate; and wherein the red, green, and blue fluorescent powder units are mounted on the TFT substrate such that one side thereof that is distant from the TFT substrate faces the LED light source and a protective layer is arranged to cover the side of the red, green, and blue fluorescent powder units that is distant from the TFT substrate and faces the LED light source in order to prevent the red, green, and blue fluorescent powder units from contact with moisture and oxygen. |
