Abstract:
1. An apparatus comprising: a light source providing light; an array of light-reflecting devices that each have a movable reflective surface, each of the light-reflecting devices for selectively reflecting the light from the light source onto a corresponding pixel of a display screen; and a processor for receiving image information and positioning the reflective surfaces of the light-reflecting devices so as to display the image on the display screen, wherein the processor selectively positions the reflective surface of at least a first of the light-reflecting devices in at least first and second positions, in the first position, the light from the light source is reflected by the first light-reflecting device onto a light absorbing material, and in the second position, the light from the light source is reflected by the first light-reflecting device onto a first pixel of the display screen, the first pixel being different than the pixel of the display screen that corresponds to the first light-reflecting device.
