White balance adjusting method and device of liquid crystal display panel

Abstract

The invention provides a white balance adjustment method for a liquid crystal display panel, and the method comprises the steps: determining interpolation parameters corresponding to two endpoint frame rates of a frame rate interval containing a current frame rate according to the current frame rate of the liquid crystal display panel and an interpolation parameter table; obtaining an intermediatewhite balance data table corresponding to the endpoint frame rate according to the interpolation parameter and the original white balance data table; performing linear interpolation on the two intermediate white balance data tables corresponding to the two endpoint frame rates to obtain a target white balance data table corresponding to the current frame rate; and performing white balance adjustment on the liquid crystal display panel according to the target white balance data table. According to the invention, the target white balance data table corresponding to the current frame rate can becontinuously generated along with the change of the frame rate of the liquid crystal display panel, so that the liquid crystal display panel can achieve the optimal white balance adjustment effect atany frame rate, and the display effects of the liquid crystal display panel at different frame rates tend to be consistent. The invention further provides a white balance adjusting device of the liquid crystal display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method and device for adjusting white balance of a liquid crystal display panel. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) device has become a mainstream product among display devices due to its many advantages such as thin body, power saving and no radiation. Most of the LCD devices in the existing market are backlight LCD devices, and the backlight LCD devices include an LCD panel and a backlight module. The working principle of the LCD panel is: by applying a voltage to two parallel glass substrates, the deflection angle of the liquid crystal molecules erected between the two glass substrates is controlled, thereby refracting the light from the backlight module to produce a picture. [0003] Since the white field color coordinates of different LCD panels are different in different degrees, if the corresponding white bala...

Problems solved by technology

However, with the development of display technology, LCD panels now have a variety of frame rates. When the frame rate of the LCD panel changes, the original white balance data table is still used to adjust the white balance of the LCD panel, which cannot make the LCD panel achieve The best white balance adjustment effect, resulting in a large difference in the display effect of the same LCD panel at different frame rates
