Abstract
In this paper, we propose a novel voltage programmed pixel circuit with
p-type low temperature polycrystalline silicon thin-film transistors (LTPS
TFTs) for active-matrix organic light-emitting displays (AMOLEDs) with an
enhanced electrical stability and uniformity. Through extensive numerical
analysis based on experimental data of p-type LTPS TFT and OLED, we confirm
that the proposed pixel circuit can compensate for both the mobility variation
and threshold voltage shift of TFTs.
