Method of driving display panel and display apparatus for performing the same

A display apparatus comprising:

• a display panel that displays an image;
• a voltage generator that generates a gate on voltage, a first gate off voltage and a second gate off voltage;
• a signal generator that generates a clock signal based upon the gate on voltage and the second gate off voltage;
• a discharging part that generates a first panel gate off voltage substantially the same as the first gate off voltage and a second panel gate off voltage substantially the same as the second gate off voltage in a first operating mode, and that generates a first panel gate off voltage greater than the first gate off voltage and a second panel gate off voltage greater than the second gate off voltage in a second operating mode;
• and
• a gate driver that generates a gate signal based upon the clock signal and the first and second panel gate off voltages, and that outputs the gate signal to a gate line of the display panel.

A method for driving a display panel, comprising:

• driving a gate line of a display panel during a turn-on period based upon a gate on voltage having a voltage value for turning on a switching element coupled to the gate line of the display panel;
• discharging the gate line based upon a first gate off voltage and a second gate off voltage for discharging the gate line of the display panel, first gate off voltage and the second gate off voltage having voltage values for turning off the switching element;
• and
• using the second gate off voltage during a first time period from a turn-off moment of the switching element and using the first gate off voltage after the first time period from the turn-off moment of the switching element to maintain the switching element turned off,
• wherein the gate on voltage has a positive value and the first gate off voltage and the second gate off voltage have negative values, the second gate off voltage being more negative than the first gate off voltage.
