Abstract
A driving circuit of active matrix organic electroluminescence diode is disclosed. Each pixel includes three TFTs and two capacitors. A gate of scan reset TFT is controlled by the scan line of the row where the pixel is located and a drain of scan reset TFT is connected to the data line of the column where the pixel is situated. Detect TFT is 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 the threshold voltage (Vth) of driving TFT. Therefore, the sum of capacitors Cd and Ct will drive the driving TFT to output the corresponding current to the organic electroluminescence element.
