Display panel driving apparatus and method with over-driving of first and second image data

A display panel driving apparatus comprising:

• an over-driving circuit configured to receive first image data, and to output second image data using first over-driving data and second over-driving data, the first over-driving data being generated according to previous frame data and present frame data for a minimum blank period between the previous frame data and the present frame data of the first image data, the second over-driving data being generated according to the previous frame data and the present frame data for a maximum blank period between the previous frame data and the present frame data of the first image data;
• a data driving circuit configured to output a data signal based on the second image data to a data line of a display panel;
• and
• a gate driving circuit including a gate signal generator configured to output a generated gate signal to a gate line of the display panel.
