Novel Photo-Aligned Color Filters and Optical Interference Elements for LCD-Projection

摘要

Novel, optically birefringent thin films of photo-aligned nematic as well as cholesteric polymeric liquid crystals with controllable spatial uniaxiality are presented. Positive and negative birefringent optical thin film modules are shown to enable a vast number of optical thin-film key elements for direct view displays and LCD projectors. Photo-aligned, non-absorbing and bright, interference color filters, cholesteric band modulation filters as well as positive and negative optical retarders and their applications in LCD-projection are shown.
