Abstract
A system and method for determining the current of a pixel circuit and an organic light emitting diode (OLED). The pixel circuit is connected to a source driver by a data line. The voltage (or current) supplied to the pixel circuit by the source driver. The current of the pixel and the OLED can be measured by a readout circuit. A value of a voltage from the measured current can be extracted and provided to a processor for further processing.
