Problems solved by technology

[0003] Most of the current large-size liquid crystal display panels use VA (Vertical Alignment, vertical alignment technology) liquid crystal or IPS (In-Plane Switching, in-plane switching) liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has higher production efficiency and low Advantages in manufacturing cost, but in terms of optical properties, compared with IPS liquid crystal technology, there are obvious defects in optical properties; that is, some large-scale display panels, especially VA-type liquid crystal drivers, rapidly saturate with voltage at large viewing angles, resulting in high-quality viewing angles. The contrast and color cast are seriously worse than the image quality of the face-to-face view, that is, there is a big-view character cast problem

Abstract

The invention discloses a driving method of a display panel, a driving system and a display device. The method comprises the following steps of receiving a first color signal in an RGB system, and converting the first color signal into a first color space signal in an HSV system; acquiring a current color saturation signal of the first color space signal, judging whether a color saturation value of the current color saturation signal reaches a preset threshold value or not, and if yes, acquiring a preset adjustment coefficient corresponding to the current color saturation signal; performing adjustment processing on the current color saturation signal by using the preset adjustment coefficient; finishing the adjustment processing of the color saturation signal to obtain a second color spacesignal in the HSV system; and converting the second color space signal into a second color signal in the RGB system to drive the display panel. The color saturation is adjusted to improve the color cast problem.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a driving method, a driving system and a display device of a display panel. Background technique [0002] With the development and progress of science and technology, liquid crystal displays have become the mainstream products of displays due to their thin body, power saving and low radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Most of the current large-size liquid crystal display panels ...
