LCoS microdisplays provide poor efficiency when used with a conventional color wheel in projection systems. This paper will present a new design that replaces the color wheel with a rotating color drum. Throughput of the color drum projector is compared to a system using 3 scanning prisms and to a 3 panel system. System colorimetry and white point correction will be discussed.
