摘要： A pixel circuit of an organic electroluminescent display device and a method of driving the same. In the pixel circuit, a capacitor has a first electrode connected to a gate of a driving transistor, and a second electrode connected to a drain of a switching transistor. Further, a compensation voltage applying transistor is connected to the second electrode of the capacitor. The compensation voltage applying transistor compensates for a difference in IR-drops of a power supply voltage in response to a previous emission control signal. Further, the compensation voltage applying transistor cuts off the compensation voltage in an initialization period, thereby preventing a source of a data voltage and a source of the compensation voltage from being shorted with each other. Additionally, a threshold voltage compensation transistor is connected between the gate and the drain of the driving transistor. Therefore, a difference in threshold voltages of driving transistors is compensated.
