摘要:
An AMOLED driving circuit and driving method adds an additional switching transistor to a 2T1C driving circuit. An additional switching transistor is connected to the high voltage source, a scan line and a node connected a source terminal of a driving transistor of the 2T1C driving circuit and the light-emitting device. The additional switching transistor and an original switching transistor of the 2T1C driving circuit are activated when the scan line outputs high voltage. At the time, a low voltage of a PWM voltage is added to the high voltage source not to drive the driving transistor, and a storage capacitor stores a voltage of the image data signal. When the two switching transistors turn off and a high voltage of the PWM voltage is provided to the high voltage source, the driving transistor is driven to generate a driving current to the light-emitting device.

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.
