Restraining for switching effects in an AC driving pixel circuit of the OLED-on-silicon

Abstract:

The AC driving scheme for OLEDs,which uses the pixel circuit with two transistors and one capacitor(2T1C),can extend the lifetime of the active matrix organic light-emitting diode(AMOLED) on silicon,but there are switching effects during the switch of AC signals,which result in the voltage variation on the storage capacitor and cause the current glitch in OLED.That would decrease the gray scale of the OLED.This paper proposes a novel pixel circuit consisting of three transistors and one capacitor to realize...
