This work proposes a new pixel circuit of low-temperature polycrystalline-silicon thin-film transistors (LTPS-TFTs) for active-matrix organic light-emitting diode (AMOLED) displays, which combines parallel addressing scheme, current-programmed, and voltage-programmed methods. The proposed pixel circuit is used to compensate for the threshold voltage variations of driving TFT, and the current-resistance...
This work presents a new pixel circuit adopting low-temperature polycrystalline-silicon thin-film transistors (LTPS TFTs) for active-matrix organic light-emitting diode (AMOLED) displays. The proposed pixel circuit can compensate for the threshold voltage variations of the LTPS TFTs with a simple structure. Simulated results demonstrate that the OLED currents over the entire data voltage range are...
