Autostereoscopic lens sheet with planar areas
View Patent ↗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.
1. A lens sheet, comprising at least one refractive region and at least one non-refractive region, wherein the lens sheet is configured to allow relatively clear viewing of stereoscopic images through each refractive region and nonstereoscopic images through each non-refractive region.
2. A lens sheet as in claim 1 , wherein the refractive region is comprised of lenticules.
3. A 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 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 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 lens sheet as in claim 5 , wherein the refractive region defines a picture area having an aspect ratio of approximately 1.3:1.
7. An 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 configured to provide clear stereoscopic images transmitted by the display and at least one non-refractive region configured to provide clear planar images transmitted by the display.
8. An autostereoscopic display 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. An autostereoscopic display as in claim 8 , wherein the refractive region defines a picture area having an aspect ratio of approximately 1.3:1.
10. An autostereoscopic display as in claim 7 , wherein the refractive region is comprised of lenticules.
11. An autostereoscopic display as in claim 10 , wherein the lenticules are oriented at a right angle to a horizontal edge of the lens sheet.
12. An autostereoscopic display as in claim 10 , wherein the lenticules are oriented at an acute angle to a horizontal edge of the lens sheet.
13. A lens sheet, comprising:
at least one refractive region, said at least one refractive region configured to receive stereoscopic images and relatively clearly display the stereoscopic images to a viewer; and
at least one non-refractive region, said at least one non-refractive region configured to receive planar images and relatively clearly display the planar images to the viewer.
14. A lens sheet as in claim 13 , wherein the refractive region is comprised of lenticules.
15. A lens sheet as in claim 14 , wherein the lenticules are oriented at a right angle to a horizontal edge of the lens sheet.
16. A lens sheet as in claim 14 , wherein the lenticules are oriented at an acute angle to a horizontal edge of the lens sheet.
17. A lens sheet as in claim 13 , 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.
18. A lens sheet as in claim 17 , wherein the refractive region defines a picture area having an aspect ratio of approximately 1.3:1.
