Abstract
We propose a new active matrix organic light-emitting diode (AMOLED) pixel circuit in which the compensation for the thin film transistor and OLED performance variation and/or degeneration is performed periodically in a separate frame time. In the other frame time, the AMOLED pixel works without any compensation operation, so that the whole row time is used for driving. Only three transistors and two capacitors are required to construct the pixel circuit. It is demonstrated that both accurate compensation and high driving speed can be realized in the separate frame compensated AMOLED pixel circuit.
