Abstract

This work presents a pixel circuit adopting low-temperature polycrystalline-silicon thin-film transistors (LTPS-TFTs) composed of 5T2C for active-matrix organic light-emitting diode (AMOLED) displays. The proposed circuit can effectively compensate for VDD IR-drop and threshold voltage variation with current-bias voltage-programmed structure, also preventing the flicker phenomenon on displays.
