MEMS-driven optical package with micro-LED array
View Patent ↗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.
1. 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.
2. The optical multiplexing package of claim 1 , wherein the at least on additional color is selected from the group consisting of cyan, amber, deep green, dark blue or royal blue, or a cool 10,000 kelvin white.
3. The optical multiplexing package of claim 1 , wherein the movable stage is a linear comb-based device.
4. The optical multiplexing package of claim 1 , wherein the movable stage moves linearly along two axes.
5. The optical multiplexing package of claim 1 , wherein the movable stage moves in more than one axis.
6. The optical multiplexing system of claim 1 , wherein an angular resolution of the package creates a data transmission system where a ray of light may only be sensed from a single location in a space and that by illuminating one pixel that is only visible by one sensor, a closed communication channel is created, wherein the communication channel is used for calibration of the package.
7. 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.
8. The substrate of claim 7 , wherein the at least on additional color is selected from the group consisting of cyan, amber, deep green, dark blue or royal blue, or a cool 10,000 kelvin white.
9. The substrate of claim 7 , wherein the movable stage is a linear comb-based device.
10. The substrate of claim 7 , wherein the movable stage moves linearly along two axes.
11. The substrate of claim 7 , wherein the movable stage moves in more than one axis.
12. The substrate of claim 7 , wherein an angular resolution of the package creates a data transmission system where a ray of light may only be sensed from a single location in a space and that by illuminating one pixel that is only visible by one sensor, a closed communication channel is created, wherein the communication channel is used for calibration of the package.
