Abstract
An analogue buffer for driver-integrated poly-Si TFT LCDs is described where large mismatches of poly-Si TFT in threshold voltage and mobility are compensated. The buffer has a very simple configuration consisting of an nMOS, a pMOS, three switches, and a capacitor. Because of its simple and compact architecture, the panel size can be kept small even with integrated driver circuits. The measurement results show the analogue data buffer can achieve 4.5 bit resolution.
