Abstract

A new pixel circuit employing LTPS TFT for AMOLED is proposed. The proposed one can eliminate both the threshold voltage variation of the driving TFT and the supply voltage drop. The simulation results indicate that the proposed circuit significantly improves the non-uniformity of output current by the new compensation operation.
