Abstract: A pixel circuit for an active matrix organic light emitting diode (AMOLED) and other active matrix displays is disclosed. The pixel circuit is programmed by the voltage supplied through a data line. An electrical current through a light emitting device for a known LED voltage and a pixel current for a pixel programed with a known data signal can be measured by a readout circuit through the data line. A 7T1C implementation enables to pre-charge the drive transistor to a reference voltage in each drive cycle, and to pre-set the light emitting device to a reference voltage prior to emission in each cycle.
