Abstract

Generally, near seamless electronics displays may be employed in cinema and exhibition applications. Laser scanned displays may be enabled such that the display may display three dimensional (“3D”) content. A first method to enable a laser scanned display for 3D content may employ polarization, with or without polarization conversion and another method may employ multiple colors. Additionally, the envelope function that may be employed across the display may be achieved by changing laser power as a beam is scanned on the screen or by changing the dwell time of the laser beam on the pixels. One method of minimizing the effects of seams in the screen may be to reduce the screen resolution near the seams by screen design and/or laser beam dwell time or illumination energy.

Claims (44)

1. A scanned laser display apparatus, comprising:

a first panel, comprising:

a phosphor layer operable to receive at least some light from a light source and further operable to emit light;

a polarizer layer operable to receive at least some light from the phosphor layer; and

a film patterned retarder layer operable to receive at least some light from the polarizer layer; and

a wavelength selective mirror proximate to the phosphor layer, wherein the wavelength selective mirror is operable to substantially reflect RGB light and to substantially transmit light at approximately 405 nanometers.

2. The scanned laser display apparatus of claim 1 , further comprising the light source operable to scan with a beam and further operable to provide light to the first panel.

3. The scanned laser display apparatus of claim 1 , further comprising a diffuser layer operable to receive at least some light from the film patterned retarder layer.

4. The scanned laser display apparatus of claim 1 , further comprising a second wave plate operable to receive at least some light from the phosphor layer and to transmit at least some light to the polarizer layer.

5. The scanned laser display apparatus of claim 1 , wherein at least some of the light emitted by the phosphor layer forms image pixels for the scanned laser display.

6. The scanned laser display apparatus of claim 1 , wherein the film patterned retarder layer and the phosphor layer are approximately aligned relative to each other.

7. The scanned laser display apparatus of claim 1 , further comprising a second panel, wherein the first panel and the second panel may be joined together to form a seam.

8. The scanned laser display apparatus of claim 7 , wherein the first and second panel may be joined together by at least a set of joining features and a set of raised features.

9. The scanned laser display apparatus of claim 8 , wherein the first panel and the second panel may be flexible.

10. The scanned laser display apparatus of claim 7 , wherein the first panel is substantially illuminated by more than an individual light engine of an array of light engines.

11. The scanned laser display system of claim 1 , further comprising a backer substrate proximate to the phosphor layer, wherein the backer substrate has a surface away from the phosphor layer and the surface is patterned with prism shaped structures.

12. The scanned laser display apparatus of claim 7 , wherein a stereoscopic image includes a first image corresponding to a first group of pixels and a second image corresponding to a second group of pixels, wherein each of the first group of pixels and the second group of pixels are defined by a film patterned retarder alignment.

13. The scanned laser display apparatus of claim 12 , wherein the first image and the second image may be viewed with polarized glasses.

14. A scanned laser display system, comprising:

a substrate proximate to a phosphor layer, wherein the phosphor layer comprises a first set of three colors and a second set of three colors, the phosphor layer operable to emit light to produce a stereoscopic image.

15. The scanned laser display system of claim 14 , wherein the first set of three colors are operable to produce a first image and the second set of three colors are operable to produce a second image.

16. The scanned laser display system of claim 14 , further comprising at least one of a passivation layer or a protective layer proximate to the phosphor layer.

17. The scanned laser display system of claim 14 , wherein the phosphor layer comprises quantum dots.

18. The scanned laser display system of claim 14 , further comprising a second panel, wherein the first panel and the second panel may be joined together to form a seam.

19. The scanned laser display system of claim 18 , wherein the first panel and the second panel may be flexible.

20. The scanned laser display system of claim 18 , further comprising an array of light engines wherein the first panel is substantially illuminated by more than an individual light engine of the array of light engines.

21. A stereoscopic display system, comprising:

a light source operable to scan with a beam and further operable to produce light energy;

at least a first substrate and a second substrate joined together to form the appearance of a seam and operable to receive light from the light source;

a first phosphor layer proximate to the first substrate and a second phosphor layer proximate to the second substrate and operable to transmit light for stereoscopic images; and

an array of light engines, wherein the first substrate is substantially illuminated by more than an individual light engine of the array of light engines.

22. The stereoscopic display system of claim 21 , wherein the seam between the first and second substrates is aligned to be in a gap between pixels on at least one of the first or second substrate.

23. A scanned laser display apparatus, comprising:

a first panel, comprising:

a phosphor layer operable to receive at least some light from a light source and further operable to emit light;

a polarizer layer operable to receive at least some light from the phosphor layer;

a film patterned retarder layer operable to receive at least some light from the polarizer layer; and

a second panel, wherein the first panel and the second panel may be joined together to form a seam.

24. The scanned laser display apparatus of claim 23 , wherein the first and second panel may be joined together by at least a set of joining features and a set of raised features.

25. The scanned laser display apparatus of claim 24 , wherein the first panel and the second panel may be flexible.

26. The scanned laser display apparatus of claim 23 , wherein the first panel is substantially illuminated by more than an individual light engine of an array of light engines.

27. The scanned laser display system of claim 23 , further comprising a backer substrate proximate to the phosphor layer, wherein the backer substrate has a surface away from the phosphor layer and the surface is patterned with prism shaped structures.

28. The scanned laser display apparatus of claim 23 , wherein a stereoscopic image includes a first image corresponding to a first group of pixels and a second image corresponding to a second group of pixels, wherein each of the first group of pixels and the second group of pixels are defined by a film patterned retarder alignment.

29. The scanned laser display apparatus of claim 28 , wherein the first image and the second image may be viewed with polarized glasses.
