Abstract

The invention discloses a backlight regulation method, an adjustment device and a display device. The backlight regulation method comprises steps of determining the color temperature corresponding to the current environment light according to the spectral information of the current environment light determining the total supply current which is supplied to the back light source according to the light intensity information of the current environment light, regulating the distribution current of each light source branch according to the color temperature of the current environment light and after total power supply current determines the illumination brightness of light source branches having different color domain in the back light source, and enabling the color domain of the backlight source is regulated according to the current environment light in order to realize the regulation function of the liquid crystal display product for displaying the image color gamut and improve the comfort of watching by the user. Compared with the mode that realizes the image color gamut regulation through regulating the chroma of the colorful filtering sheet, the invention can realize the flexible adjustment of the display image chroma on the basis of reducing backlight source production cost and guarantees the transmittance of the liquid crystal display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an adjustment method, an adjustment device and a display device of a backlight source. Background technique [0002] At present, mobile electronic display products have become an indispensable part of people's lives, and people have higher and higher requirements for the quality of the screen display of display products. Due to the problem of excessive color difference in the screens of existing display products, that is, the color temperature of the same batch of display products is different when displaying a white screen, so display product manufacturers have gradually increased the requirements for the uniformity of color of the screen. When producing backlight LED lamps for liquid crystal display products, the color distribution range of LEDs produced is generally large. For example, only one color block is used to make the backlight source, and the LEDs of other color bloc...
