Projection display system for reflective light valves

摘要

A projection display system for reflective light valves includes a light source for generating a light beam having RGB light components, wherein the red light component is p-polarized and the green and blue light components are s-polarized; a reflector structure having plural polarizing beam splitter and dichroic filters therein, wherein each PBS and DF reflects a preselected light component and transmits a different preselected light component, and a LCD panel for generating a light-component-specific image associated with each light component; and a projection lens for projecting an image combined from the light-component-specific images from the LCDs; wherein a light-component-specific image passes through one and only one PBS and through one and only one DF between the LCD and the projection lens.
