Abstract
A three-dimensional display device includes a display panel displaying first to nth partial images along a circumference; and an n-gonal pyramid mirror including first to nth mirrors at n side surfaces, respectively, of the n-gonal pyramid mirror, wherein the first to nth mirrors reflect the first to nth partial images, respectively, and wherein each of the first to nth mirrors substantially makes a 45 degree angle with the display panel.
Claims9
A three-dimensional display device, comprising:
- a display panel displaying first to nth partial images along a circumference;
- and
- an n-gonal pyramid mirror including first to nth mirrors at n side surfaces, respectively, of the n-gonal pyramid mirror, wherein the first to nth mirrors reflect the first to nth partial images, respectively, and wherein each of the first to nth mirrors substantially makes a 45 degree angle with the display panel,
- wherein an apex of the n-gonal pyramid mirror is below the display panel and is at a first distance from the display panel, wherein first to nth image planes corresponding to the first to nth partial images face the first to nth mirrors, respectively, and wherein each of the first to nth image planes is at the first distance from a center axis of the n-gonal pyramid mirror toward the corresponding mirror,
- wherein the first to nth image planes forms n side surfaces of an n-gonal prism, and wherein a side of a regular n-gonal upper surface of the n-gonal prism has a length of a second distance and a distance between a center of the regular n-gonal upper surface of the n-gonal prism and the side of the regular n-gonal upper surface of the n-gonal prism is the first distance.

A method of displaying a three-dimensional image, comprising:
- dividing an image to set first to nth partial images;
- displaying the set first to nth partial images along a circumference in a display panel;
- and
- reflecting the displayed first to nth partial images on first to nth mirrors, respectively, of an n-gonal pyramid mirror, wherein each of the first to nth mirrors substantially makes a 45 degree angle with the display panel,
- wherein an apex of the n-gonal pyramid mirror is below the display panel and is at a first distance from the display panel, wherein a side of a regular n-gonal upper surface of the n-gonal pyramid mirror has a length of “a”, wherein a distance between a center of the regular n-gonal upper surface of the n-gonal pyramid mirror and the side of the regular n-gonal upper surface of the n-gonal pyramid mirror is “b”, wherein a second distance is expressed by an expression, D2=(a/b)*D1, where D1 and D2 are the first and second distances, respectively, and wherein the first to nth partial images are set for adjacent partial images to be at the second distance from each other.
