摘要： A method of driving a display panel includes generating a gate on voltage, a first gate off voltage and a second gate off voltage. A clock signal is generated based upon the gate on voltage and the second gate off voltage. 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 are generated in a first operating mode. 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 are generated in a second operating mode. A gate signal is generated based upon the clock signal and the first and second panel gate off voltages to a gate line of the display panel.
