摘要：

This paper presents a new voltage driving scheme with current feedback for polycrystalline silicon (poly-Si) thin-film transistors (TFTs) to drive active matrix organic light-emitting diode (AMOLED) displays. The pixel circuit is relatively simple, which is composed of 3 TFTs and 1 capacitor. Circuit simulation results show that the proposed driving scheme can effectively suppress the influence of nonidealities of typical poly-Si TFTs including kink effects, spatial nonuniformity of the electrical characteristics. This method also presents a settling time less than 3 mu s with panel load of 100 pF/1.5 k Omega at all OLED current levels.
