9.1: Intrinsic Polarizers — Ultra Durable Dichroic Polarizers for LCD Projection

Philip J. Ralli; Gunnar H. Gunnarsson; Pradnya V. Nagarkar; Giorgio B. Trapani

High temperature polysilicon (HTPS) projection engines provide a challenging environment for film-based optical components, especially the absorbing polarizers that are critical for image formation. Intrinsic polarizers do not contain unstable dichromophores and have been shown to be well suited for this application.
