Patent ID: 6930302

Claim:
A display apparatus, comprising: a first set of light sources generating at least a first set of beams; a second set of light sources generating at least a second set of beams; one or more optical conduits conveying at least the first set of beams; a screen optically coupled at least to the one or more optical conduits; one or more actuators connected to at least the one or more optical conduits; one or more motivators at least partly inducing motion in at least the one or more actuators, the one or more optical conduits connected to the one or more actuators, and the first set of beams exiting distal ends of the one or more optical conduits; one or more patterned optical elements encoding at least positions of the one or more optical conduits on at least part of at least the second set of beams; one or more servos driving at least the one or more motivators at least partly in response to at least the encoded positions on the second set of beams; and one or more controllers electrically connected to at least the first set of light sources and electrically connected to at least the one or more servos, wherein the first set of light sources is modulated at least in intensity by at least the one or more controllers, thereby producing a picture display on the screen.
