Abstract: A display panel driving apparatus includes a control circuit, a data driver and a gate driver. The control circuit is configured to receive a first control signal for recovering a clock signal from a display signal including image data and the clock signal, and calculate a root mean square of the first control signal to output a second control signal. The data driver is configured to receive the display signal, receive the second control signal, recover the clock signal from the display signal according to the second control signal, and output a data signal based on the image data to a data line of a display panel. The gate driving part is configured to output a gate signal to a gate line of the display panel.
