Abstract: The application provides a display panel and a driving method thereof. The display panel comprises a plurality of sub-pixels arranged in a matrix, and the sub-pixels are grouped into a plurality of cell areas arranged repeatedly along the row direction and the column direction. Each cell area comprises at least two sub-pixels, with polarities of adjacent sub-pixels opposite to each other. For at least two consecutive frames during a display cycle, the gray-levels of sub-pixels in the cell area maintain unchanged while polarities of the sub-pixels are reversed.

Abstract: The present application discloses a timing controller, a polarity grayscale compensation method, and a display panel. The timing controller includes a viewing angle compensation module, an overdriving module, a lookup module, and a compensation module. A corresponding grayscale compensation table is looked up according to a comparison result of a previous frame image data and a current frame image data, a grayscale compensation is performed on the current frame image data after overdriving processing to generate a data signal after grayscale compensation, which can decrease occurrences of bright and dark lines when time-domain viewing angle compensation is switched between frames.
