Abstract
A video projector includes a reduced size spatial light modulator () that spatially modulates light from a light source () according to only a portion (e.g., ½) of a video frame at a time. A beam steerer () steers spatially modulated light from the spatial light modulator to a correspond region (e.g., upper half, lower half) of a projection screen/surface () and one or more lenses () insure that the spatially light modulator () is imaged onto the projection screen/surface ().
