Design of Hologram for Brightness Enhancement in Color LCDs

George T. Valliath; Zane Coleman; Jon Schindler; R. Polak; Robert B. Akins; Kevin W. Jelley

Transmission holographic film for brightness enhancement in full color reflective LCDs is proposed. The hologram is attached to the front of the LCD. The goal is paper-like brightness within the viewing zone under typical ambient lighting conditions. Optimum viewing and illumination angles have been identified. Modeling and measurements on holograms show that a viewing zone of 20° × 40° will provide a 12× film gain which is adequate to maintain a wide color gamut and brightness.
