- Abstract
- A novel voltage-programmed pixel circuit is proposed to achieve an active-matrix organic light-emitting display (AM-OLED) based on a low temperature polycrystalline silicon thin-film transistor (TFT) with an enhanced electrical stability and uniformity. The proposed pixel circuit consists of one driving TFT, one setup TFT, four switching TFTs, one capacitor, and four control signal lines. Through an extensive simulation work based on the HSPICE tool, it has been verified that the proposed pixel circuit can compensate for both mobility variations and threshold voltage shifts of the driving TFT.
