Abstract:
A pixel circuit, a pixel, and an AMOLED (Active Matrix Organic Light-Emitting Diode) display device comprising the pixel and a driving method thereof. The pixel circuit comprises a power supply circuit, a basic circuit and a compensation circuit, which are sequentially connected. The power supply circuit is connected to a first power supply to supply power to the basis circuit. The compensation circuit is connected to second and third power supplies, respectively, for providing difference values compensating for a voltage and current of an OLED (Organic Light-Emitting Diode). The pixel comprises an OLED and the pixel circuit. The AMOLED display device comprises the pixel circuit. By compensating for a difference between threshold and power supply voltages of a transistor, the response characteristics of the AMOLED may be improved to generate light of a same brightness, thereby meeting requirements on image uniformity and consistency of an AMOLED.
