Abstract

Disclosed are various lenticular display systems that include either a color filter array (CFA) or a colored lens array that is spaced from the pixels of an underlying display panel. In an embodiment, the CFA of a lenticular display may be operable to provides a locally ‘static color’ reproduction of images as a function of viewing angle. It may also enable the resolution of the CFA to be relatively coarse. Both separating the CFA from the panel and reducing the resolution significantly may reduce the system cost and allow higher resolution to be realized.

Claims

1. A lenticular display system, comprising:

a display panel comprising a plurality of pixels operable to output light;

a plurality of lenses disposed in the light paths of the light output by the plurality of pixels; and

a color filter array disposed between the plurality of pixels and the plurality of lenses, the color filter array being adjacent to the plurality of lenses and spaced from the plurality of pixels.

2. The lenticular display system of claim 1, further comprising a second color filter array disposed between the plurality of pixels and the plurality of lenses, the second color filter array being adjacent to the plurality of pixels.

3. The lenticular display system of claim 1, wherein the plurality of pixels comprise monochrome pixels.

4. The lenticular display system of claim 1, wherein the plurality of pixels comprise light-modulating elements.

5. The lenticular display system of claim 4, wherein the light-modulating elements comprise liquid crystal cells.

6. The lenticular display system of claim 1, wherein the plurality of pixels are arranged in a pixel array comprising a plurality of rows and columns, and further wherein the plurality of lenses are arranged in a lens array having a plurality of rows and columns that are aligned at oblique angles relative to the rows and columns of the pixel array.

7. The lenticular display system of claim 1, wherein the plurality of pixels are oriented at oblique orientations.

8. The lenticular display system of claim 1, wherein the plurality of pixels are arranged in a pixel array comprising a plurality of rows and columns, and further wherein the plurality of pixels are arranged in a Herring-bone pattern.

9. The lenticular display system of claim 1, wherein the plurality of lenses comprise cylindrical lenses.

10. A lenticular display system, comprising:

a display panel comprising a plurality of pixels operable to output light; and

a plurality of colored lenses disposed in the light paths of the light output by the plurality of pixels, the plurality of colored lenses being in spaced relation with the plurality of pixels.

11. The lenticular display system of claim 10, wherein the plurality of lenses comprise cylindrical lenses.

12. The lenticular display system of claim 10, wherein the plurality of pixels comprise monochrome pixels.

13. The lenticular display system of claim 10, wherein the plurality of pixels comprise light-modulating elements.

14. The lenticular display system of claim 13, wherein the light-modulating element pixels comprise liquid crystal cells.

15. The lenticular display system of claim 10, wherein the plurality of pixels are arranged in a pixel array comprising a plurality of rows and columns, and further wherein the plurality of lens are arranged in a lens array having a plurality of rows and columns that are aligned at oblique angles relative to the rows and columns of the pixel array.

16. The lenticular display system of claim 10, wherein the plurality of pixels are oriented at oblique orientations.

17. A method of manufacturing a lenticular display system, comprising:

providing a display panel comprising a plurality of pixels operable to output light;

disposing a plurality of lenses in the light paths of the light output by the plurality of pixels; and

disposing a color filter array between the plurality of pixels and the plurality of lenses, the color filter array being adjacent to the plurality of lenses and spaced from the plurality of pixels.

18. The method of claim 17, further comprising:

arranging the plurality of pixels in a pixel array comprising a plurality of rows and columns;

arranging the plurality of lens in a lens array having a plurality of rows and columns; and

positioning the lens array in an orientation where the rows and columns of the lens array are aligned at oblique angles relative to the rows and columns of the pixel array.

19. The method of claim 17, further comprising arranging the plurality of pixels at oblique orientations.

20. The method of claim 17, further comprising disposing a second color filter array between the plurality of pixels and the plurality of lenses, the second color filter array being adjacent to the plurality of pixels.
