Abstract

A liquid crystal field sequential color display is formed by presenting three monochromatic images corresponding to the three primary colors, that is, red, green and blue, consecutively in a repetitive sequence and at a rate greater than the flicker fusion frequency for human vision. Each field contains a monochromatic image showing how the intensity of the primary color to which it corresponds varies over the entire image area. The black and white imaging techniques typically used for forming the intensity pattern for each field are transformed into the required sequential monochromatic image patterns through the use of colored filters in one embodiment or colored light in another embodiment. The novel result is obtained by the combining of flat panel liquid crystal display technology with color display technology. This invention disclosure shows a practical method for combining these techniques into a device that will form a full color image.
