Abstract
This work presents a new low-temperature polysilicon (LTPS) thin-film transistor pixel circuit with a novel driving scheme that is based on the simultaneous emission and reverse-biased methods. During high-speed 3D operation at 240 Hz, the proposed circuit can successfully compensate for the TFT threshold voltage variation and improve the IR drop in the power line. Simulation and experimental results confirm the stability of the OLED current and the amelioration of the OLED lifetime. Furthermore, over the entire range of data voltages, the nonuniformity of OLED current is less than 5%.
