Abstract

The invention discloses a driving method and a driving system of a display module and a display device. The driving method comprises a driving process of synchronously driving a display panel and a driving process of a backlight module, wherein the display panel comprises a first color light source, a second color light source and a third color light source; the driving process of the display panel comprises the following steps: receiving a first color signal and converting the first color signal into a first hue saturation brightness space signal; adjusting the first color saturation signal to obtain a second color saturation signal; and driving the display panel by using a second color signal converted from the second color saturation signal; the driving process of the backlight module comprises: receiving a first color signal, obtaining a first color saturation signal and a second color saturation signal, and obtaining a light source adjusting coefficient; determining a minimum color light source, and adjusting the minimum color light source by using the light source adjustment coefficient to obtain a fourth brightness value; AND driving the minimum color light source by using the fourth brightness value. According to the invention, the color purity is maintained while the problem of color cast is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving method, a driving system and a display device of 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 are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module (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 colo...
