Abstract
A method is disclosed for driving a liquid crystal display panel. The liquid crystal display panel is configured to display a sequence of image frames including a plurality of alternating first frame groups and second frame groups. The method includes modulating grayscale voltage polarities for each of the plurality of second frame groups, including: dividing each of the image frames in the second frame group into a first region and a second region; setting the grayscale voltage polarities for the first region to be opposite to the grayscale voltage polarities for the second region; and modulating the grayscale voltage polarities for the image frames in the second frame group such that every two successive image frames in the second frame group have respective grayscale voltage polarity patterns that are opposite to each other. Also disclosed are a timing controller and a liquid crystal display apparatus.
