DISPLAY PANEL, METHOD OF DRIVING THE SAME AND DISPLAY APPARATUS HAVING THE SAME

摘要

A display panel driving apparatus includes resistance parts and a common voltage output part. The resistance parts have each resistance value and respond to address signals, and selectively output resistance values. The common voltage output pat outputs a common voltage to a display panel based on the resistance value. Therefore, the common voltages can be selectively outputted on the display panel. The common voltages are quickly provided and changed. The accuracy of the common voltages can be improved.
