Abstract
An improved efficiency liquid crystal display device (10) includes at least two pairs of electrode disposed above and below, and on two sides of each display pixel (12). Each pair of electrodes is capable of applying an electrical field to a layer of liquid crystal material disposed therebetween. The applied electrical fields cause the liquid crystal materials to switch from a first to a second optical state corresponding to an opaque and transparent state. The result is a display device having higher optical efficiencies, and faster display response times. Multiple intermediate optical states are possible by applying varying amounts of electrical charge to the two pairs of electrodes at the same time.

A flat panel display device including at least one display pixel element, said flat panel display device comprising:
- first and second display substrates arranged in spaced, parallel relationship, each said display substrate having at least one display electrode disposed thereon;
- third and fourth display electrodes disposed between and electrically isolated from said first and second display substrate electrodes;
- and
- a layer of liquid crystal material disposed between said first and second display substrate electrodes and said third and fourth display electrodes, and defining said at least one display pixel.
A flat panel display device comprising a plurality of display pixels, each said pixel comprising a first electrode disposed on a first display substrate, a second electrode disposed on a second display substrate, a third electrode disposed between, and electrically insulated from said first and second electrodes, a fourth electrode disposed between and electrically insulated from said first and second electrodes, and a layer of a nematic liquid crystal material disposed between said electrodes.
