Abstract
A pixel circuit with an organic light emitting diode (OLED) includes an OLED, a driving switch, an enabling switch, a compensation circuit, and a data switch. Through the compensation circuit, the data switch, and the control of a compensation voltage, a voltage at the control terminal of the driving switch of the pixel circuit is set according to a data voltage and the absolute value of a threshold voltage of the driving switch. Hence, the driving current determined by the driving switch relates to the data voltage.
