Abstract:
A display panel driving apparatus includes a data driving circuit, a gate driving circuit and a common voltage outputting circuit. The data driving circuit is configured to output a data signal based on image data to a data line of a display panel. The gate driving circuit is configured to output a gate signal to a gate line of the display panel. The common voltage outputting circuit is configured to output a common voltage according to grayscale values of the image data and set the common voltage in varying grayscale value intervals according to a decrease of the grayscale values of the image data.
