A light engine. The light engine can include an illumination source that produces light for projecting a still or motion video image. The light engine also can include a condenser configured to receive unpolarized light from the illumination source and output a focused beam of unpolarized light. A polarizing assembly arranged downstream of the condenser can be configured to receive the focused beam of unpolarized light and output substantially polarized light. The polarized light can be directed to a transmissive liquid crystal display panel that receives the substantially polarized light and transmits a video image.
