Abstract
An optical light package includes an optical output lens, an optical filter located thereunder and between the output lens and LEDS, a tray of LEDs arrayed on a stage mounted on a linear comb based MEMS device that is distributed in such a way that the stage is movable, and a driver that controls movement of the stage.

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.
A substrate comprising multiple optical multiplexing packages controlled by a driver, wherein the optical multiplexing packages comprise:
- 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 LEDs 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;
- wherein the driver controls movement of the stage such that the light passing through the lens changes with movement of the stage, wherein the driver uses input from at least one sensor that provides information to the driver about location and timing of the movable stage and/or substrate;
- and
- wherein the movable stage is constantly in motion during operation of the multiplexing package.
An array of optical multiplexing packages, wherein each of the optical multiplexing packages has 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.
