Abstract
A circuit for driving an AMOLED pixel is disclosed. The circuit includes: a first transistor, a second transistor, and a grayscale storage capacitor, wherein a connecting path is arranged between an input end of a data line and an input end of a scanning line, by which an afterimage is eliminated when an AMOLED display device is turned off in a predetermined turned-off sequence of external control signals and voltages on each portion of the circuit.
