Abstract: A display driving device configured to control a display panel including pixel units to display, includes: an over driver compensation module configured to, when a first polarity frame image is displayed, perform line over driver compensation on the pixel units based on line over driver compensation data corresponding to the first polarity frame image, to determine a target over driver grayscale of the pixel units; and to, when a second polarity frame image is displayed, perform line over driver compensation on the pixel units based on line over driver compensation data corresponding to the second polarity frame image, to determine a target over driver grayscale of the pixel units. The first and second polarity are opposite to each other, and the line over driver compensation data corresponding to the first polarity frame image is different from the line over driver compensation data corresponding to the second polarity frame image.
