Abstract

A ferroelectric liquid-crystal (FE-LC) shutter array with a poly-Si thin-film transistor (TFT) driver that has 256 dots (300-dots/in resolution) and is 21.7 mm long is discussed. A low-temperature process and excimer laser doping process were used to reduce the device cost. Since the TFT driver is capable of driving the FE-LC in the static mode and reduces the number of outlet electrodes, this device offers the advantages of high contrast ratio (over 20:1), compact device size, and low cost
