Embodiment Construction
[0055] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0056] The present invention provides a method for improving the color gamut of a liquid crystal display terminal. In the first embodiment of the method for improving the color gamut of a liquid crystal display terminal in the present invention, refer to Figure 8 , the method for improving the color gamut of the liquid crystal display terminal includes:
[0057]Step S10, acquiring the spectral energy distribution of the liquid crystal display terminal backlight corresponding to the visible light band;
[0058] The liquid crystal display terminal displays images of different colors through the addition principle of RGB (red, green and blue) three primary colors to realize the reproduction of different colors. Therefore, to improve the color expressiveness of the liquid crystal display terminal, that is, to improve th...

A method for improving color gamut of a liquid crystal display terminal, comprising: obtaining a spectral energy distribution of a visible light band corresponding to a backlight source of a liquid crystal display terminal (S10); determining a three-primary-color band in the visible light band according to the spectral energy distribution (S20); filtering visible spectral energy of a transition band in the visible light band other than the three-primary-color band to improve the visible light purity of the three-primary-color band, so as to improve the color gamut value of the liquid crystal display terminal (S30). Also provided is a liquid crystal display terminal. The liquid crystal display terminal decreases the full width at half maximum of a three-primary-color band of a backlight source of the liquid crystal display terminal and improves the visible light purity of the three-primary-color band, such that the backlight source can display more colors on the basis of the three primary colors having higher purity, thereby improving the color gamut value of the liquid crystal display terminal and the displaying quality of the liquid crystal display terminal.
Description
technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a method for improving the color gamut of a liquid crystal display terminal and a liquid crystal display terminal. Background technique [0002] With the development of liquid crystal display technology, consumers' requirements for display quality of liquid crystal display terminals (such as liquid crystal televisions, etc.) are gradually increasing. Existing liquid crystal display terminals generally use traditional high color gamut phosphor LEDs (Light Emitting Diodes, light emitting diodes) to achieve high color gamut. In the CIE1931 chromaticity coordinate system, the NTSC color gamut cannot reach 100%, resulting in the display picture of liquid crystal display terminals The quality is not high. Contents of the invention [0003] The main purpose of the present invention is to provide a method for improving the color gamut of a liquid crystal display termin...
