Compensator components may be disposed in front of and, in some cases, behind the liquid crystal cell. In some embodiments, a STN LC cell with a twist angle of 270 degrees may be used. In other embodiments, a STN LC cell with a twist angle ranging between just greater than 270 degrees and 285 degrees may be used. Also disclosed is a system incorporating the various disclosed STN LC shutters.
