Abstract

A lenticular display may be formed with convex curvature. The lenticular display may have a lenticular lens film with lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display. To enable more curvature in the display while ensuring satisfactory stereoscopic display performance, the display may have stereoscopic zones and non-stereoscopic zones. A central stereoscopic zone may be interposed between first and second non-stereoscopic zones. The non-stereoscopic zones may have more curvature than the stereoscopic zone. To prevent crosstalk within the lenticular display, a louver film may be incorporated into the display. The pixel array may have a diagonal layout and may be covered by vertically oriented lenticular lenses.

First claim

The invention claimed is:

1. A display comprising:
a substrate;
an array of pixels formed on the substrate and arranged in a plurality of rows and columns; and
a lenticular lens film formed over the substrate, wherein the lenticular lens film comprises a plurality of elongated lenticular lenses, wherein a first plurality of pixels in the array of pixels has a first layout, wherein a second plurality of pixels in the array of pixels has a second layout that is different than the first layout, and wherein, in each row, pixels having the first layout alternate with pixels having the second layout.

2. The display defined in claim 1 , wherein the first layout is flipped to form the second layout.

3. The display defined in claim 1 , wherein the first layout is vertically flipped to form the second layout.

4. The display defined in claim 1 , wherein each row extends in a first direction and wherein at least some of the rows are shifted in the first direction relative to a preceding row.

5. The display defined in claim 4 , wherein the elongated lenticular lenses extend in a second direction that is orthogonal to the first direction.

6. The display defined in claim 1 , wherein each pixel in the array of pixels has a first sub-pixel of a first color, a second sub-pixel of a second color, and a third sub-pixel of a third color.

7. The display defined in claim 6 , wherein the first sub-pixel is adjacent to an upper edge of the pixel in the first layout.

8. The display defined in claim 7 , wherein the first sub-pixel is adjacent to a lower edge of the pixel in the second layout.

9. The display defined in claim 8 , wherein the second sub-pixel is adjacent to the lower edge of the pixel in the first layout and wherein the second sub-pixel is adjacent to the upper edge of the pixel in the second layout.

10. The display defined in claim 9 , wherein the first color is blue, wherein the second color is red, and wherein the third color is green.

11. The display defined in claim 1 , wherein the first plurality of pixels comprises every other column of pixels.

12. The display defined in claim 1 , wherein the columns are diagonal columns.

13. The display defined in claim 1 , wherein each row extends in a first direction and wherein at least some of the rows are shifted in the first direction relative to a preceding row by a distance that is greater than 0 and less than a center-to-center pitch between adjacent pixels.

14. A display comprising:
a substrate;
an array of pixels formed on the substrate and arranged in a plurality of rows and columns; and
a lenticular lens film formed over the substrate, wherein the lenticular lens film comprises a plurality of elongated lenticular lenses, wherein a first plurality of pixels in the array of pixels has a first layout, wherein a second plurality of pixels in the array of pixels has a second layout that is different than the first layout, wherein, in adjacent rows, pixels having the first layout alternate with pixels having the second layout, and wherein the first layout is vertically flipped to form the second layout.

15. The display defined in claim 14 , wherein, in each row, pixels having the first layout alternate with pixels having the second layout.

16. A display comprising:
a substrate;
an array of pixels formed on the substrate and arranged in a plurality of rows and columns, wherein each pixel in the array of pixels has a first sub-pixel of a first color; and
a lenticular lens film formed over the substrate, wherein the lenticular lens film comprises a plurality of elongated lenticular lenses, wherein a first plurality of pixels in the array of pixels has a first layout, wherein a second plurality of pixels in the array of pixels has a second layout that is different than the first layout, wherein, in adjacent rows, pixels having the first layout alternate with pixels having the second layout, wherein the first sub-pixel is adjacent to an upper edge of the pixel in the first layout, and wherein the first sub-pixel is adjacent to a lower edge of the pixel in the second layout.

17. The display defined in claim 16 , wherein each pixel in the array of pixels has a second sub-pixel of a second color and a third sub-pixel of a third color.

18. The display defined in claim 17 , wherein the second sub-pixel is adjacent to the lower edge of the pixel in the first layout and wherein the second sub-pixel is adjacent to the upper edge of the pixel in the second layout.
