Abstract: The present disclosure discloses a liquid crystal display panel and a compensation method thereof. The compensation method firstly acquires a plurality of consecutive and alternating odd-numbered frame grayscale data and even-numbered frame grayscale data, then determines a minimum grayscale difference, and determines a gamma voltage difference corresponding to the grayscale difference according to a curve of a relation between grayscales and gamma voltages, followed by obtaining a correction value for a common voltage based on the gamma voltage difference. The flicker phenomena can be improved by adjusting the common voltage only once with the correction value.

Abstract: This application discloses a pixel driving architecture, a display panel, and a display device. The pixel driving architecture uses three hybrid inversion modes of column inversion, one-plus-two-line point inversion, and two-line point inversion to drive the display panel. This improves the subjective vertical flicker brought about when the Strip architecture is driven by the driving mode of column inversion alone, and compared with the one-plus-two-line point inversion or two-line point inversion driving mode, the charging effect of the panel is better, and can make the twill disappear.
