6.3: Field-Sequential Smectic LCD with TFT Pixel Amplifier

A field-sequential color smectic LCD has been developed using low-temperature poly-Si TFTs. An active-load type TFT pixel amplifier is used to drive a V-shaped-switching smectic LC without voltage fluctuation. The optical response time is 300 μs for a field frequency of 180 Hz. This LCD is capable of displaying high-quality motion-picture images.
