ABSTRACT:
A display system includes blue, green, and red laser light sources and light shaping devices which receive the laser light from the laser light sources and shapes the light into a number of approximately identical beamlets. The beamlets are modulated individually and the modulated beamlets are combined. The combining results in an output of beamlets, each of which comprises three input beamlets of each of the colors red, green, and blue. The resultant beamlets can then be scanned onto a display screen.
