Abstract: A display panel driving apparatus includes a load controlling circuit, a data driver and a gate driver. The load controlling circuit is connected to a control line transferring a recovery timing control signal for controlling recovery of a clock signal from a display signal including image data and the clock signal, and is configured to control a load of the control line according to a glitch level of the recovery timing control signal. The data driver is configured to receive the display signal, receive the recovery timing control signal through a connection to the control line, recover the clock signal from the display signal according to the recovery timing control signal, and output a data signal based on the image data to a data line of a display panel.
