Abstract
A liquid crystal display provides a high quality color image and efficient energy utilization. A layer of liquid crystal material is controlled by a transparent electrode matrix. A matrix of (primary color emitting) phosphors, each in alignment with a transparent electrode, is fixed to a surface of a fiber optic plate. A source of fluorescent energy excites the phosphors. A filter located behind the fiber optic plate reflects visible light, both ambient and that emitted from the phosphors. The fiber optic late acts as a relay lens and prevents cross pixel color contamination while the generation of backlight by the phosphor conversion of fluorescent to visible energy is a highly efficient process.
