Abstract
A micromechanical mirror combined with a photoluminescent screen is able to efficiently use light from the light source. In such a device, the light source produces light that is directed onto the micromechanical mirror. The micromechanical mirror then selectively reflects the light onto a photoluminescent screen. The light excites the photoluminescent screen to produce the desired picture. The photoluminescent screen may include sets of pixels that convert light from the light source to provide the desired picture. Typically, each pixel set includes a red, green and blue portion although any suitable combination of colors and number of pixels may be used. Each pixel set portion converts the light received from the light source into its respective color by photoluminescence. Alternatively, the photoluminescent screen may include transparent and/or scattering portions instead of photoluminescent portions of a certain color when the light source has a spectrum which is limited to one color.
