Abstract: A display apparatus is disclosed. In one aspect, the apparatus includes a display panel including pixels connected to gate lines and data lines, a gate driver driving the gate lines, a data driver driving the data lines, and a control circuit controlling the gate driver and the data driver to display an image on the display panel. The control circuit applies a common voltage to the display panel. The control circuit compares the common voltage applied to the display panel and a feedback common voltage fedback from the display panel and applies a gate-on voltage having a voltage level corresponding to the compared result to the gate driver.
