Abstract
A method of projecting an image includes emitting a light beam, forming an image from the light beam, and attenuating the light beam by controlling an AC signal between two voltage levels. The image is formed by projecting image frames. The switching of the AC signal from one voltage level to the other is controlled between projections of the image frames.
