ABSTRACT:
A liquid crystal apparatus, such as a display, film, or other material or device, includes liquid crystal material in a containment medium which are cooperative selectively to scatter or to transmit light. Fluorescent dye colors, brightens and/or whitens the scattered light and may effect a light amplification function. Total internal reflection, intereference or both principles may be used to increase the path length that scattered light travels in the apparatus.
