Current supply device for a pixel of an active matrix light emitting display device

摘要

The driver drives the thin film transistor (TFT) (Tr2) for supplying power to an electroluminescent (EL) element (E1), by charging and discharging of light emitting power holding capacitor (C2) by a switching element (SW2). An independent claim is also included for active matrix type light emitting display device.
