Patent ID: 7511771

Claim:
An image projection system for projecting a two-dimensional, color image, comprising: a) a projection screen; b) a laser assembly for emitting a composite beam comprised of a plurality of laser beams of different wavelengths toward the projection screen; c) a scanner for sweeping the composite beam in a pattern of scan lines across the projection screen, each scan line having a number of pixels; d) a controller operatively connected to the laser assembly and the scanner, for causing selected pixels to be illuminated, and rendered visible, by the composite beam to produce the image; and e) a light-transmissive member as part of the projection screen, including phosphor particles for converting one of the laser beams having a wavelength to a different wavelength to create the image in red, blue and green colors, and a binding material for binding the phosphor particles, the binding material having an index of refraction matching an index of refraction of the phosphor particles.
