  • Systems and method for displaying images with reduced power consumption
    Patent number: 8508452
    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.
    Type: Grant
    Filed: February 29, 2012
    Date of Patent: August 13, 2013
    Assignee: Wistron Corporation
    Inventors: Ken A. Nishimura, Ian Hardcastle, Pierre Mertz, Rene Helbing, Charels W. Hoke, Barry Bronson
