Abstract

A display device may include a panel including a plurality of pixels and an optical layer. The display device may include a processor configured to generate an image of the panel based on a location relationship between the pixels and the optical elements so that a plurality of rays corresponding to the image propagate evenly at a viewing distance. The location relationship is based on an optical parameter of the optical layer.

First claim

What is claimed is:

1. A display device comprising:
a panel comprising a plurality of pixels; and
an optical layer configured to generate a light field using a plurality of optical elements,
wherein the optical layer is arranged with respect to the panel to eliminate a repetition periodicity between the plurality of pixels and the plurality of optical elements.

2. The display device of claim 1 , wherein an optical parameter associated with the optical elements comprises a slanted angle between a first line corresponding to the optical elements and a second line corresponding to the pixels, a pitch between the optical elements, an offset location between the panel and the optical layer, a gap between the panel and the optical layer, or a combination selected from the slanted angle, the pitch, the offset location, and the gap.

3. The display device of claim 2 , wherein the slanted angle is based on a number of first pixels corresponding to a direction of a first axis in the panel in comparison to a number of second pixels corresponding to a direction of a second axis in the panel, and
the direction of the first axis and the direction of the second axis are orthogonal, and the number of the first pixels comprises a number with a decimal when the number of the second pixels is a positive integer.

4. The display device of claim 2 , wherein the pitch is based on a number of third pixels matched to a single one of the optical elements, and
the number of the third pixels comprises a number with a decimal.

5. The display device of claim 2 , wherein the slanted angle is based on a line that connects a first point at a top of the panel to a second point at a bottom of the panel.

6. The display device of claim 2 , wherein the slanted angle is within an angle range of which an artifact is minimized.

7. The display device of claim 1 , wherein the processor is configured to generate the image based on a direction of a ray propagating according to the location relationship.

8. The display device of claim 1 , wherein the processor is configured to generate the image based on whether a direction of a ray propagating according to the location relationship is toward a viewpoint from among a plurality of viewpoints, the plurality of viewpoints being divided in a viewing range.

9. The display device of claim 1 , wherein the processor is configured to,
determine a viewpoint image corresponding to a direction of a ray based on the location relationship, the viewpoint image comprising a number with a decimal, and
generate the image based on a plurality of viewpoint images and the viewpoint image.

10. The display device of claim 1 , wherein the processor is configured to obtain a calibration parameter and generate information associated with the location relationship based on the calibration parameter.

11. A display method comprising,
obtaining information associated with a location relationship between a plurality of pixels in a panel and a plurality of optical elements in an optical layer, the location relationship being based on an optical parameter of the optical layer; and
generating an image of the panel based on the information,
wherein the optical layer is arranged with respect to the panel to eliminate a repetition periodicity between the plurality of pixels and the plurality of optical elements.

12. The display method of claim 11 , wherein the optical parameter comprises a slanted angle between a first line corresponding to the optical elements and a second line corresponding to the pixels, a pitch between the optical elements, an offset location between the panel and the optical layer, a gap between the panel and the optical layer, or a combination selected from the slanted angle, the pitch, the offset location, and the gap.

13. The display method of claim 12 , wherein the slanted angle is based on a number of first pixels corresponding to a direction of a first axis in comparison to a number of second pixels corresponding to a direction of a second axis in the panel, and
the direction of the first axis and the direction of the second axis are orthogonal, and the number of the first pixels comprises a number with a decimal when the number of the second pixels is a positive integer.

14. The display method of claim 12 , wherein the pitch is based on a number of third pixels matched to a single one of the optical elements, and
the number of the third pixels comprises a number with a decimal.

15. The display method of claim 12 , wherein the slanted angle is within an angle range of which an artifact is minimized.

16. The display method of claim 11 , wherein the generating generates the image based on a direction of a ray propagating according to the location relationship.

17. The display method of claim 11 , wherein the generating comprises,
determining whether a direction of a ray propagating according to the location relationship is toward a viewpoint from among a plurality of viewpoints, the plurality of viewpoints being divided in a viewing range; and
generating the image based on a result of the determining.

18. The display method of claim 11 , wherein the generating comprises,
determining a viewpoint image corresponding to a direction of a ray based on the location relationship, the viewpoint image comprising a number with a decimal; and
generating the image based on a plurality of viewpoint images and the viewpoint image.

19. The display method of claim 11 , wherein the obtaining comprises,
obtaining a calibration parameter; and
generating information associated with the location relationship based on the calibration parameter.

20. A non-transitory computer-readable medium including computer readable instructions, which when executed by a processor, cause the processor to implement the method of claim 11 .
