摘要： 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.

摘要： The main circuit of each stage of the high-reliability shift register circuit is composed of transistors, and the turn-on time for the four transistors are only 1˜2 pulse time within one frame time. Transistors construct an inverter circuit which continuously offers a high-level supply voltage that controls activities of transistors so as to continuously offer a low-level supply voltage to the first node and the output terminal such that avoids the first node and the output terminal being in a floating state. Besides, one of the transistor acts as a charging circuit that extends the lifetime of another transistor. This circuit avoids the affection on the behavior of the shift register circuit that is caused by an a-Si (amorphous silicon) TFT under a sustained stress.

摘要： A pixel circuit relating to an organic light emitting diode (OLED) is provided by the invention, and if the circuit configuration (5T1C) thereof collocates with suitable operation waveforms, the current flowing through an OLED in the OLED pixel circuit is not varied along with the variation of the conducting voltage (Voled_th) of the OLED in a long time driving current stress, and is not varied with the threshold voltage (Vth) shift of a TFT used for driving the OLED. Accordingly, not only the brightness decay of the OLED in the long time stress is mitigated or compensated, but also the brightness uniformity of the applied OLED display is substantially improved.
