Color adjustment method and device, liquid crystal display

A color adjustment method, comprising:

• obtaining mapping parameters for primary colors of a pixel;
• mapping the primary colors of the pixel to new primary colors according to the mapping parameters;
• and
• displaying an image on a screen according to the new primary colors.

A color adjustment device, comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to:
• obtain a current color gamut mode of a pixel;
• convert the current color gamut mode of the pixel to a preset color gamut mode, to obtain a blue component of the pixel in the preset color gamut mode;
• and
• perform an intensity weakening regulation on the blue component of the pixel in the preset color gamut mode.

A liquid crystal display, comprising:

• a backlight source;
• a lower polarizer over the backlight source;
• an optical filter over the lower polarizer, the optical filter being configured to filter out ultraviolet radiation, or blue component of a pixel of the liquid crystal display, or both the ultraviolet radiation and the blue component of the pixel;
• a liquid crystal layer over the optical filter;
• and
• an upper polarizer over the liquid crystal layer.
