Abstract

A dual mode autostereoscopic lens sheet. The lens sheet has at least one refractive region and at least one non-refractive region. When the lens sheet is held in intimate juxtaposition with a display, stereoscopic content may be viewed in the refractive region while planar content may be simultaneously viewed in the non-refractive region. In a preferred embodiment, the non-refractive region forms a vertical column on one end of the lens sheet and the refractive region forms a vertical column on the other end of the lens sheet. Advantageously, the refractive region defines a picture area having an aspect ratio of approximately 1.3:1.

Claims

1. A dual mode autostereoscopic lens sheet, comprising at least one refractive region and at least one non-refractive region.

2. A dual mode autostereoscopic lens sheet as in claim 1, wherein the refractive region is comprised of lenticules.

3. A dual mode autostereoscopic lens sheet as in claim 2, wherein the lenticules are oriented at a right angle to a horizontal edge of the lens sheet.

4. A dual mode autostereoscopic lens sheet as in claim 2, wherein the lenticules are oriented at an acute angle to a horizontal edge of the lens sheet.

5. A dual mode autostereoscopic lens sheet as in claim 1, wherein the non-refractive region forms a vertical column on one end of the lens sheet and the refractive region forms a vertical column on the other end of the lens sheet.

6. A dual mode autostereoscopic lens sheet as in claim 5, wherein the refractive region defines a picture area having an aspect ratio of approximately 1.3:

1.

7. A autostereoscopic display, comprising:

a display;

a lens sheet held in intimate juxtaposition with the display, wherein the lens sheet includes at least one refractive region and at least one non-refractive region.

8. A dual mode autostereoscopic lens sheet as in claim 7, wherein the non-refractive region forms a vertical column on one end of the lens sheet and the refractive region forms a vertical column on the other end of the lens sheet.

9. A dual mode autostereoscopic lens sheet as in claim 8, wherein the refractive region defines a picture area having an aspect ratio of approximately 1.3:

1.

10. A dual mode autostereoscopic lens sheet as in claim 7, wherein the refractive region is comprised of lenticules.

11. A dual mode autostereoscopic lens sheet as in claim 10, wherein the lenticules are oriented at a right angle to a horizontal edge of the lens sheet.

12. A dual mode autostereoscopic lens sheet as in claim 10, wherein the lenticules are oriented at an acute angle to a horizontal edge of the lens sheet.
