Abstract

The invention discloses a driving method and a driving system for a display module and a display device. The driving method comprises a display panel driving process and a backlight module driving process which are synchronously carried out; the display module comprises a plurality of first color light sources and second color light sources, which are controlled independently; the driving processof a display panel comprises the steps of: receiving first color signals and converting the first color signals into first color space signals; carrying out color saturation regulation on the first color space signals and converting to obtain second color signals under an RGB system; and driving the display panel by using the second color signals; and the backlight module driving process comprisesthe steps of: obtaining a light source regulation coefficient; regulating a first brightness value corresponding to the first color light sources and / or the second color light sources by using the light source regulation coefficient to obtain a second brightness value; determining main color tone light sources from the first color light sources and the second color light sources; and driving themain color tone light sources by using the second brightness value. According to the invention, problems of color offset and color saturation presentation can be improved.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a driving method and a driving device for a display module. 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] Among them, in an undisclosed solution used by the inventor, the color shift ...
