- Claim: 4. The panel display of claim 1 wherein the means for separating include an off-axis LED light source provided in a sub-pixel.
- Claim: 5. The panel display of claim 4 wherein a beam axis of the off-axis LED light source is aligned in a horizontal plane or a substantially horizontal plane.
- Claim: 6. The panel display of claim 1 wherein the means for multiplexing include gratings.
- Claim: 7. The panel display of claim 6 wherein the gratings are one-dimensional line-gratings, and the grating lines are straight, parallel, equally-spaced, and aligned in a vertical or substantially vertical direction.
- Claim: 8. The panel display of claim 6 wherein the gratings are two-dimensional cross-gratings, and a first set of grating lines are straight, parallel, equally-spaced, and aligned in a vertical or substantially vertical direction, and a second set of grating lines are straight, parallel, equally-spaced, and aligned in a horizontal or substantially horizontal direction.
- Claim: 9. The panel display of claim 6 wherein the gratings are amplitude-type gratings.
- Claim: 10. The panel display of claim 9 wherein a duty cycle of the amplitude-type grating is selected to match a predetermined maximum supportable number of the hypothetical plurality of viewers.
- Claim: 11. The panel display of claim 6 wherein the gratings are phase-type gratings.
- Claim: 12. The panel display of claim 11 wherein a peak-to-peak thickness of the phase-type grating is selected to match a predetermined maximum supportable number of the hypothetical plurality of viewers.
- Claim: 13. The panel display of claim 6 wherein a pitch of the grating is selected based on a wavelength of a color of a corresponding sub-pixel.
- Claim: 14. The panel display of claim 1 wherein the means for separating and the means for multiplexing are selected such that no VVAL shares any volume with any VVAR at a given distance from the display.
- Claim: 15. The panel display of claim 1 wherein a center point of a VVAL is separated from a center point of a corresponding VVAR by a distance of 60 mm±10%.
- Claim: 16. The panel display of claim 1 wherein a center point of a VVAL or VVAR is separated from a center point of an adjacent VVAL or VVAR by 0.5 meters±10%.
- Claim: 17. The panel display of claim 1 wherein the array of pixels includes LCD sub-pixels, each LCD pixel being back-illuminated via light emitting diodes (LED) or laser diodes (LD).
