The invention discloses a liquid crystal display device and a backlight driving method, comprising: a display module, used for displaying based on received video data; Backlight; analysis module, used to analyze the video data, to obtain the display color range corresponding to the current display content; drive module, connected to the backlight module and the analysis module, to dynamically display the color based on the range of the display color Select to switch the backlight corresponding to the emission spectrum. The invention also provides a backlight driving method. The liquid crystal display module and the backlight driving method of the present invention change the traditional way of providing backlight with a fixed spectrum backlight, and replace it with a way of dynamically switching backlight with different spectrum backlights according to the display content, which can greatly improve its color saturation.
Description
technical field [0001] The invention relates to the display field, in particular to a liquid crystal display device capable of realizing high color gamut and a backlight driving method thereof. Background technique [0002] Liquid crystal display is currently the most common flat panel display technology, widely used in various fields such as TV, mobile phone, vehicle, industry and medical treatment. Its principle is mainly based on the birefringence effect of liquid crystal molecules to modulate the transmittance of polarized light, so as to realize light and dark display. Because of its non-active luminescent characteristics, color saturation (that is, color gamut, used to measure the richness of display color expression) is limited by backlight and color filters, and it is difficult to meet people's continuously improving requirements for display color quality. Although the development of quantum dot display technology in recent years has made great progress in improving...
