Problems solved by technology

Since the common reference voltage (Vcom) of these specific display screens fluctuates the most when the ADS type liquid crystal panel is driven by a column inversion electric field, the load increases due to the fluctuation of the common reference voltage, resulting in these several display screens The power consumption increases, which causes problems such as poor picture display quality and effects
[0007] So far, there is no driving method that can ensure the quality of the picture display and minimize the power consumption of the LCD panel.

Abstract

The invention provides a driving method, a driving system and a display device for an LCD panel. The driving method comprises the steps that the data signals of a first frame are saved, whether the data signals of the current input frame of the LCD panel are the data signals of the first frame are judged, the LCD panel adopts a first electric field inversion mode if the data signals of the current input frame of the LCD panel are the data signals of the first frame, and otherwise the LCD panel adopts a second electric field inversion mode, wherein the power consumption of displaying of the first frame by adopting the first electric field inversion mode is smaller than the power consumption of displaying of the first frame by adopting the second electric field inversion mode. Through the adoption of the driving method and the driving system, the input frame can be displayed by adopting an electric field inversion mode of lower power consumption, and the display power consumption of the LCD panel can be lowered to the minimum while the frame display quality is guaranteed.
