Abstract
This invention discloses the product of a liquid crystal display (LCD) device and the method of making same, wherein the resultant product is an improved color oriented LCD in which the liquid crystal material and the color dye material are intimately comingled within an enclosure of polymer material and/or encapsulated within the structure of microdroplets. The resulting color displayed by this LCD device is controlled by the selective application of electrical parameters, namely, voltage and frequency, to permit the droplets within a display device to absorb, scatter, or transmit light, and/or color, or mixture of colors, determined by the dye materials and the applied electrical parameters employed.
