Abstract

The invention provides a display controller and a driving method of a liquid crystal display panel. The display controller is electrically connected with the liquid crystal display panel and comprises a data processor and a control signal generator. The driving method comprises the following steps: judging whether an image data signal is a first image data signal or a section image data signal; when the image data signal is the first image data signal, providing a first polar signal to the panel; and when the image data signal is the second image data signal, providing a second polar signal to the panel. According to the invention, the display quality can be ensured and consumed power can be reduced.

Description

technical field [0001] The invention relates to a display controller and a driving method of a liquid crystal display panel, in particular to a display controller and a driving method of a liquid crystal display panel which can ensure display quality and save power consumption. Background technique [0002] At present, liquid crystal display devices (Liquid Crystal Display, LCD) have been widely used in various electronic products. Commonly used driving methods for LCDs are, for example, Dot Inversion, Frame Inversion, Column Inversion, and Row Inversion. Among them, the screen inversion driving has the problem that the screen flicker is easily felt, while the line inversion driving has the problem that vertical stripes are easy to appear. Therefore, dot inversion driving and column inversion driving are more commonly used as LCD driving methods, especially, dot inversion driving is more often used in large LCDs. [0003] Although dot inversion driving can have better disp...
