Abstract
A method and a system for displaying images are provided. In the method, a pixel is provided that includes a layer of ferroelectric material and a layer of liquid crystal material. A first electric field is momentarily applied to the pixel to electrically polarize the ferroelectric layer to a first polarization. The first polarization is then used to maintain the liquid crystal material in a first orientation corresponding to a first apparent brightness of the pixel.
