Organic light emitting display device, pixel circuit of the same and driving method thereof
Abstract:
An organic light emitting display device, a pixel circuit of the organic light emitting display device and a method of driving the same are disclosed. The pixel circuit comprises a driving transistor, a first transistor, a second transistor, a third transistor, a fourth transistor, a first capacitor, a second capacitor, a light emitting diode and a compensating diode. The degradation of the light emitting diode is compensated by the compensating diode. Since the degradation phenomena of the light emitting diode is compensated by the compensating diode, the light emitting diode is able to maintain an effective and normal brightness while using the same driving voltage, thereby ensuring higher display quality of images and scenes of the organic light emitting display device.
