<p>A display system includes a display (10) including a substrate (15), a first transparent conductor (20) formed on the substrate, a layer of cholesteric liquid crystal (30) having a plurality of stable optical states at ambient temperatures located over the first conductor, and a light absorbing second conductor (35) located over the layer of cholesteric liquid crystal for forming an image wise thermal pattern in response to an image wise pattern of light; and a writing device including a flash light (52), a mask (54) for forming the image wise pattern of light, and means for applying an electrical field across the first and second conductors, and a display drive with electrical contacts (50) for applying an electrical field to the conductors of the display; and a controller connected to the light source and the display drive drive for controlling the intensity of the electrical field and actuating the light source to create an image on the display. <IMAGE></p> |
