Abstract
A method for compensating a threshold voltage drift of a thin film transistor comprises: controlling a drain and a gate of the thin film transistor to have a same voltage; and keeping the voltage at the gate of the thin film transistor unchanged and controlling the voltage at the drain of the thin film transistor to be equal to a voltage at a source of the thin film transistor.
