Latest Patents

Kam H Wan holds a patent for a "Wide viewing-angle dye-doped TN LCD with retardation films." This invention provides a wide viewing-angle twisted nematic liquid crystal display. The wide viewing-angle is achieved through the application of properly aligned retardation films between a twisted nematic liquid crystal cell and one of two polarizers. Additionally, the liquid crystal is doped with dichroic dye molecules. These elements not only increase the viewing-angle but also improve the chromaticity of the display. The retardation films convert the polarization state of the transmitted light to a more linearly polarized light, achieving a higher contrast ratio at various scanning directions. The dichroic dye molecules further enhance the contrast ratio along a 90-degree scanning direction. By combining these elements, a much wider viewing-angle is achieved.
