Abstract
A projection display device includes a light source module, a switch unit, and micro-scanning mirrors. The light source module provides a light beam. The switch unit receives the light beam and switches a transmission direction of the light beam to the corresponding one of the micro-scanning mirrors during each of periods. The micro-scanning mirrors cause the light beam to scan over projection surfaces to form images. The projection display device can project the images on the projection surfaces without image brightness loss.
