Abstract

A liquid crystal device biased by an alternating current having a predetermined frequency higher than the dispersion frequency of the liquid crystal material. The liquid crystal device exhibits inherent capacitance across its input terminals which is resonated by an inductor to result in a higher bias current and reduction of image smear of images displayed by such device.
