1. An optical multiplexing package having an expanded color gamut comprising:
an optical lens;
an array of light emitting elements (LEEs), arrayed on a movable stage that is mounted on a MEMS array, wherein the array of LEEs form pixels, wherein the LEEs project light through the optical lens, wherein the pixels include red, green, blue, and at least one other color pixel, and wherein the array of LEEs is visible to different viewers located at different locations in space;
a driver that controls movement of the stage such that the light passing through the lens changes with movement of the stage;
a sensor that provides information to the driver about location and timing of the movable stage; and
wherein the movable stage is constantly in motion during operation of the multiplexing package.
