Title: CIRCUIT AND METHOD FOR DRIVING AMOLED PIXELS
Abstract:
A circuit and a method for driving AMOLED pixels are disclosed, the circuit comprising a first transistor (T1); a second transistor (T2); and a grayscale storage capacitor (Cst), wherein the circuit further comprises a third transistor (T3) with a source connected to a drain of the first transistor (T1), a drain connected to a ground, and a gate for inputting a turn-offcontrol signal. By applying the turn-off control signal and turning off voltages for each portion of the circuit in a predetermined order, the third transistor (T3) is turned on.
