New analog buffer circuit using low temperature polycrystalline thin film transistors for active matrix displays

Abstract

Two types new simple source follower circuit using low-temperature polycrystalline silicon thin film transistors (LTPS-TFTs) as analogue buffer for the integrated data driver circuit of active matrix liquid crystal displays (AMLCDs) and active matrix light emitting diodes (AMOLEDs) are proposed. Analogue buffer designs are discussed and verified by SPICE simulation results.
