Abstract
An apparatus for projecting an image includes a light source, a polarization modulator, a projection lens, and a mirror. The mirror is positioned between the light source and the modulator and blocks a cross-sectional portion of the light from the light source from reaching the modulator. Light from the light source that reaches the modulator has its polarization modulated in accordance with a video signal to be displayed to produce a modulated signal corresponding to the video signal. The modulated light signal is reflected from the mirror into a projection lens.
