Ferroelectric liquid-crystal shutter array with poly-Si TFT driver

A novel ferroelectric liquid-crystal (FE-LC) shutter array with a poly-Si thin-film-transistor (TFT) driver has been fabricated which has 256 dots (300 dots/in. resolution) and is 21.7 mm long. The TFT driver is capable of driving the FE-LC in the static mode and reduces the number of outlet electrodes. This results in a device with the advantages of high contrast ratio (over 20 to 1), compact device size, and low cost. >
