ABSTRACT:
A driving circuit of active matrix organic electroluminescence display is disclosed. Each pixel includes four TFTS and two capacitors. A gate of scan TFT is controlled by the scan line of the row where the pixel is located and a drain of scan TFT is connected to the data line of the column where the pixel is situated. Reset TFT and detect TFT are controlled by one threshold-lock line. One capacitor Cd is used to store data voltage (Vdata) of image signals and the other capacitor Ct is used to store threshold voltage (Vth) of drive TFT. Therefore, the sum of capacitors Cd and Ct will drive TFT to output a corresponding current to the organic electro luminescence element.
