Display device with modulated gate-on gate-off voltages and driving method thereof

摘要

A display panel includes a plurality of gate lines and a plurality of pixels disposed thereon, a gate driver which applies a gate signal to the gate lines, and a controller which controls the gate driver, where the controller includes a signal controller which generates a scanning start signal and a gate clock signal comprising a plurality of pulses, where the scanning start signal instructs to start a scanning of the gate signal, and a driving voltage modulator which generates a modulated gate-on voltage and a modulated gate-off voltage based on a basic gate-on voltage and a basic gate-off voltage, where the driving voltage modulator adds an overshoot voltage corresponding to a rising edge of a pulse of the gate clock signal to the basic gate-on voltage or adds an undershoot voltage corresponding to a falling edge of the pulse of the gate clock signal to the basic gate-off voltage.
