Embodiment Construction

[0044] Specific structural and functional details disclosed herein are representative only and for purposes of describing example embodiments of the present invention. This invention may, however, be embodied in many alternative forms and should not be construed as limited to only the embodiments set forth herein.

[0045] figure 1 It is a schematic diagram of the present invention adopting the design of primary and secondary pixels to improve the problem of color shift.

[0046] Large-size LCD panels, especially VA (Vertica Aignment, Vertical Alignment Technology) LCD panels, corresponding to large viewing angles, the brightness rapidly saturates with voltage, resulting in a serious deterioration in viewing angle image quality contrast and color shift compared with the front view image quality.

Abstract

The invention discloses a driving method and driving system of a display module and a display device. The driving method includes a synchronously driven display panel driving process and backlight module driving process. The display module comprises a plurality of independently controlled first color light sources and second color light sources. The driving method of the display module comprises the steps of receiving a first color signal, and converting the first color signal into a first color space signal; carrying out color saturation adjustment on the first color space signal, and converting the first color space signal to obtain a second color signal; and driving the display panel by using the second color signal. The backlight module driving process comprises the steps of acquiringa first color space signal and a second color space signal to obtain a light source adjustment coefficient; adjusting a first brightness value corresponding to the first color light sources and / or thesecond color light sources by using the light source adjustment coefficient to obtain a second brightness value; and driving the first color light sources and / or the second color light sources by using the second brightness value. The problem of color deviation and color saturation presentation can be improved according to the invention.

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 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 (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 us...
