Abstract

The present application discloses a display module driving method, a driving system, and a display device, including a synchronously driven display panel driving process and a backlight module driving process: the display panel driving process includes: after receiving the first color signal, Convert to the first color saturation brightness space signal; adjust the first color saturation signal with the preset adjustment coefficient to obtain the second color saturation signal; convert the second color saturation signal into the second color signal, drive the display The panel; the driving process of the backlight module includes: receiving the first color signal, calculating the average signal of the first color saturation signal and the average signal of the second color saturation signal; determining the minimum color light source, and obtaining the minimum light source corresponding to the minimum color light source After adjusting the coefficient, adjust the minimum color light source to obtain the fourth brightness value, and use the fourth brightness value to drive the minimum color light source; this application maintains the performance of color purity while improving color cast.

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] In an undisclosed solution used by the inventor, the color cast can b...
