By substituting four-thin film transistor (TFT) pixel circuit for two-TFT pixel circuit  the luminous uniformity has great improved  but it requires more components than the two-TFT pixel circuit. There are some barriers needed to resolve to utilize hydrogenated amorphous silicon transistor to lit OLED  such as low field effect mobility  low output current and threshold voltage shift. In this article  a two-a-Si:H TFT pixel circuit was designed  which consisted of one named switching TFT and the other named driving TFT. The driving TFT gate line structure modified and a data signal timing improved were reported. The modified driving TFT can provide enough current about 30 microampere to lit OLED and the novel data signal timing can provide a constant current to OLED by restraining the driving TFT threshold voltage variation. In the novel data signal timing  the control signals to the driving TFT gate include a data signal and a reverse data signal. The signals alteration is performed either at a frame rate or at a line rate. By experiments  the driving TFT output current value is plotted as a function of the time in different reversed voltage value. When the magnitude of the positive data signal and the negative data signal is equal  the variety of Vth  is smallest  about 1.28V after a fixed stressing time of 1.33104min  which shows the novel data signal timing can improved the driving TFT output-input current stability.   Experiment study on laser surface hardening for tooling high speed steel 会议论文  OAI收割 1998 Liu W.
