摘要： A pixel driving circuit of an organic light emitting diode (OLED) includes a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a capacitor, and an OLED. The operation of the pixel driving circuit includes three stages including discharging, data writing, and emitting. The pixel driving circuit compensates the threshold voltage of the transistor in the stage of data writing, so the driving current of the OLED can be irrelevant to the variations of threshold voltages.
