Abstract

Methods and systems for displaying full-color three-dimensional imagery are provided. A first color set, having a first color spectrum, is defined to include a first set of LEDs. The first color set is assigned to a first color-coded image perspective. A second color set, having a second color spectrum, is defined to include a second set of LEDs. The second color set is assigned to a second color-coded image perspective. The full-color three-dimensional imagery is caused by activating, alternatively, at least two LEDs of the first color set or the second color set and one LED of a remaining color set and displaying the three-dimensional image based on the first image perspective and the second image perspective.

Claims

1. A method of displaying full-color three-dimensional imagery comprising:

defining a first color set, having a first color spectrum, to include a first set of light sources, wherein the first color set is assigned to a first color-coded image perspective;

defining a second color set, having a second color spectrum, to include a second set of light sources, wherein the second color set is assigned to a second color-coded image perspective;

displaying the first color-coded image perspective on the first set of light sources, wherein displaying the first color-coded image perspective comprises passing wavelengths associated with the first color set through a first strip filter adapted to transmit the first color spectrum and to reflect or absorb the second color spectrum; and

displaying the second color-coded image perspective on the second set of light sources.

2. The method of claim 1, wherein the first color spectrum, includes wavelengths corresponding to each of a first red LED, a first green LED, and a first blue LED.

3. The method of claim 1, wherein the second color spectrum, includes wavelengths corresponding to each of a second red LED, a second green LED, and a second blue LED.

4. The method of claim 1, wherein displaying the second color-coded image perspective comprises, passing wavelengths associated with the second color set through a second strip filter adapted to transmit the second color spectrum and to reflect or absorb the first color spectrum.

5. The method of claim 1, wherein the first color spectrum is different from the second color spectrum.

6. The method of claim 1, wherein the first color-coded image perspective is displayed on one of odd or even rows or columns of the display device, and the second color-coded image is displayed on the remaining rows or columns of the display device.

7. A computer readable storage medium storing instructions that, when executed by processor, causing the processor to perform steps comprising:

defining a first color set, having a first color spectrum, to include a first set of light sources, wherein the first color set is assigned to a first color-coded image perspective;

defining a second color set, having a second color spectrum, to include a second set of light sources, wherein the second color set is assigned to a second color-coded image perspective;

displaying the first color-coded image perspective on the first set of light sources, wherein displaying the first color-coded image perspective comprises passing wavelengths associated with the first color set through a first strip filter adapted to transmit the first color spectrum and to reflect or absorb the second color spectrum; and

displaying the second color-coded image perspective on the second set of light sources.

8. The computer readable storage medium of claim 7, wherein the first color spectrum, includes wavelengths corresponding to each of a first red LED, a first green LED, and a first blue LED.

9. The computer readable storage medium of claim 7, wherein the second color spectrum, includes wavelengths corresponding to each of a second red LED, a second green LED, and a second blue LED.

10. The computer readable storage medium of claim 7, wherein the first color spectrum is different from the second color spectrum.

11. The computer readable storage medium of claim 7, wherein displaying the second color-coded image perspective comprises passing wavelengths associated with the second color set through a second strip filter adapted to transmit the second color spectrum and to reflect or absorb the first color spectrum.

12. The computer readable storage medium of claim 7, wherein the first color-coded image perspective is displayed on one of odd or even rows or columns of the display device, and the second color-coded image is displayed on the remaining rows or columns of the display device.

13. An apparatus for displaying full-color three-dimensional imagery comprising:

a first set of light sources defining a first color set, the first color set having a first color spectrum, wherein the first color set is configured to display a first color-coded image perspective;

a second set of light sources defining a second color set, the second color set having a second color spectrum, wherein the second color set is configured to display a second color-coded image perspective;

a light guide;

a liquid crystal display;

a first strip filter adapted to transmit the first color spectrum and to reflect or absorb the second color spectrum; and

a second strip filter adapted to transmit the second color spectrum and to reflect or absorb the first color spectrum.

14. The apparatus of claim 13, wherein the first color spectrum, includes wavelengths corresponding to each of a first red LED, a first green LED, and a first blue LED.

15. The apparatus of claim 13, wherein the second color spectrum, includes wavelengths corresponding to each of a second red LED, a second green LED, and a second blue LED.

16. The apparatus of claim 13, wherein the first color spectrum is different from the second color spectrum.

17. The apparatus of claim 13, wherein the first color-coded image perspective is displayed on one of odd or even rows or columns of the display device, and the second color-coded image is displayed on the remaining rows or columns of the display device.
