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.
Claims12
An optical multiplexing package having an expanded color gamut comprising:
- an optical lens;
- an array of LEDs that form pixels mounted on a movable stage, wherein the LEDs project light through the optical lens, wherein the pixels include red, green, blue, and at least one other color pixel;
- a driver that controls movement of the stage such that the light passing through the lens changes with movement of the stage;
- and
- a sensor that provides information to the driver about location and timing of the movable stage;
- wherein the movable stage is constantly in motion during operation of the multiplexing package.
3 more elements
A substrate comprising multiple optical multiplexing packages controlled by a driver, wherein the optical multiplexing packages comprise:
- an optical lens;
- an array of LEDs that form pixels mounted on a movable stage, 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 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;
- wherein the movable stage is constantly in motion during operation of the multiplexing package.
