Abstract
A pixel circuit and organic light-emitting diode (OLED) display including the same are disclosed. In one aspect, a pixel circuit comprises an OLED electrically connected between a first node and a low power supply voltage, a driver electrically connected to the OLED at the first node and configured to drive the OLED with a voltage corresponding to a data signal based at least in part on a scan signal, a read-out unit configured to measure an anode current of the OLED based at least in part on a read control signal, and a compensation unit electrically connected to the OLED at the first node and configured to provide the OLED with a compensation current corresponding to a compensation data signal based at least in part on the measured anode current and a compensation control signal.
