Abstract

A system, method and apparatus is provided for a display projector. The display projector and components thereof provide a variety of systems, methods and apparatuses which can be combined in various ways. In some embodiments, a display projector is provided which is highly efficient based on the use of an RGB LCoS system. In some embodiments, laser diodes are used as a light source and in other embodiments, LEDs (light emitting diodes) are used as a light source. In some embodiments, a projected overlay is used. In some embodiments, an alignment system and method is provided. In some embodiments, an integrated optical polarization combining prism is used. In some embodiments, dynamic range is increased through adjustment of the projected image. In some embodiments, a single set of projection optics are used to project three different colors in an alternating fashion. Each of the features mentioned with regard to some embodiments may be combined with the other features mentioned in various embodiments of systems, methods and apparatuses.
