Abstract

In order to realize high-brightness and high-quality pictures for an ultra portable LCOS (liquid crystal on silicon) projector, a high-performance optical system comprising an illumination system with PCU (polarization converter unit), a new color-management unit with a polarized system and a small-size LCOS panel have been developed. Our new technologies are applicable to various projection display systems.
