Abstract

The embodiment of the present invention discloses an automatic adjustment method and device for the white balance of an LCD screen. Through the adjustment of the R channel only adjusting the R channel adjustment parameters, the G channel only adjusting the G channel adjustment parameters, and the B channel only adjusting the B channel adjustment parameters to achieve It solves the time-consuming automatic adjustment of the white balance of the LCD screen, and solves the technical problem of long time-consuming by adjusting one of the parameters of R, G, and B so that the x, y, and Y values ​​are adjusted accordingly.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for automatically adjusting the white balance of an LCD screen. Background technique [0002] Liquid crystal display LCD consists of two glass substrates with liquid crystal poured in the middle. Due to the obvious optical anisotropy of liquid crystal molecules, the liquid crystal molecules can be controlled by changing the energizing voltage of the glass substrate through the driving chip, resulting in changes in its refractive index and light transmittance, thereby modulating the light of the background light source to realize image display. Because there are certain differences in hardware such as the LCD liquid crystal panel and the backlight module, the color temperature of the LCD screen cannot reach the color temperature required by the user, so it is necessary to adjust the color temperature. [0003] The existing common method for adjusting ...
