Claim 22:
23. A method of producing illumination, the method comprising:
controlling each set of a plurality of sets of microLEDs to operate in a mode selectable from a set of modes that includes a stereoscopic projection mode to provide a stereoscopic image and a general illumination mode to provide general lighting of an area without providing any images to the area; and
in the stereoscopic projection mode:
receiving at least one video data signal; and
in response to the at least one video data signal, independently selecting, from a set of states that include activated, deactivated, and dimmed, a state of each of the microLEDs in each of the plurality of sets of microLEDs to simultaneously produce a first emission profile from a first subset of the at least some of the plurality of sets of microLEDs and a second emission profile from a second subset of the at least some of the plurality of sets of microLEDs and directing the first emission profile toward a first emission angle to form a first image of a scene and the second emission profile toward a second emission angle to form a second image of the scene, the first image and the second image corresponding to different viewing angles of the scene to form a three-dimensional stereoscopic image, the second subset of the at least some of the plurality of sets of microLEDs being different from the first subset of the at least some of the plurality of sets of microLEDs.
