Abstract
A novel 2T1C pixel circuit design for active matrix organic light emitting diodes (AM-OLEDs) based on the asynchronous double-gate low-temperature polycrystalline silicon thin-film transistors (LTPS-TFTs) is proposed and verified by SPICE simulation. First, we simulate and verify the asynchronous double-gate polycrystalline silicon thin-film transistors; then, we simulate the transient response of this pixel circuit; last, the simulation solutions are compared with those of traditional 2T1C pixel circuits. The results show that this pixel circuit has good driving ability and high immunity to the variation of poly-Si TFT characteristics.
