Abstract: A display panel and its driving method are provided. When a grayscale difference is less than a first preset grayscale threshold, a first driving voltage is determined to drive the display panel for displaying a current frame to be displayed. When the grayscale difference is greater than or equal to the first preset grayscale threshold and less than or equal to a second preset grayscale threshold, a second driving voltage is determined to drive display. When the grayscale difference is greater than the second preset grayscale threshold, an overdrive lookup table is invoked to determine a third driving voltage for driving display. The second driving voltage is greater than the first driving voltage and less than the third driving voltage. The second preset grayscale threshold is greater than the first grayscale threshold. This approach reduces brightness differences between different positions and prevents the occurrence of momentary watermarks or mura.
