Abstract
The present invention discloses a method for driving a tin film transistor, and more particularly, a method for driving a thin film transistor of a liquid crystal display. Voltage for driving a gate is changed such that peak values of the gate pulse voltage in positive field periodic scanning time and negative field periodic scanning time are not equal, and the difference therebetween is not larger than double of voltage peak value of a data signal line. Therefore, voltage reduction of liquid crystal capacitor can be decreased without enlarging the capacitance thereof. Further, since the gate voltage applied is smaller in a half of each period, the thin film transistor of the liquid crystal display is less influenced by an electric field and thus the voltage stress is reduced.
