Abstract

An AMOLED display device and driving method thereof is provided. In the AMOLED display device, the anode layer on the pixel area comprises a first anode and a second anode formed around and separated from the first anode, the first sub OLED is composed of the first anode, the OLED functional layer and the cathode on the first anode, and the second sub OLED is composed of the second anode, the OLED functional layer and the cathode on the second anode; for each pixel area, a pixel driving circuit is formed correspondingly; the pixel driving circuit is coupled to the first and the second anode; when operated, the pixel driving circuit sends the first current and the second current different from the first current to the first anode and the second anode so that the luminance strength of the first sub OLED and the second sub OLED is the same.
