Shin Tson Wu: Reflective and transflective liquid crystal display using a wire grid polarizer. University of Central Florida, Brian S Steinberger, Law Offices of Brian S Steinberger P A, December 20, 2005: US06977702 (116 worldwide citation)

A device structure for single cell gap reflective and transflective liquid crystal displays (TF-LCDs). For an entirely reflective LCD, the imbedded wire-grid polarizer (WGP) serves as a polarization-dependent for the ambient light. For a transflective TF-LCD, the WGP only covers the reflective pixel ...
