Reduction of electrooptical response times of a field-effect liquid-crystal device: Application to dynamic-driven real-time matrix display

A shortening of the response time of a field-effect device in which liquid Crystals with a positive dielectric anisotropy were used and operated in the tunable birefringence mode has been achieved. This technique has been applied to a 40 × 40 matrix display operated in a 3:1 selection scheme; a real time display with buildup and decay lags of 5 and 20 ms, respectively, and with contrast ratios of 5:1-30:1 has been realized.
