Abstract

A three-dimensional (3D) image display includes a display panel including regions arranged in a first direction and an image converting unit that converts a two-dimensional (2D) image displayed on the display panel into a 3D image. Each of a first region and a second region includes columns sequentially arranged in the first direction and a first pixel pattern or a second pixel pattern is included in each of the columns. The first and second pixel patterns each include first, second, third, and fourth color cells arranged in a second direction different from the first direction. The arrangement of the first to fourth color cells in the first pixel pattern is different from the arrangement of the first to fourth color cells in the second pixel pattern. The first and second pixel patterns are alternately arranged in corresponding columns of the first and second regions.

Claims

1. A three-dimensional (3D) image display, comprising:

a display panel including a plurality of regions arranged in a first direction; and

an image converting unit disposed on the display panel to convert a two-dimensional (2D) image displayed on the display panel into a 3D image,

wherein each of a first region and a second region of the plurality of regions comprises a plurality of columns sequentially arranged in the first direction, a first pixel pattern or a second pixel pattern is included in each of the columns, the first and second pixel patterns each comprise first, second, third, and fourth color cells arranged in a second direction different from the first direction, the arrangement of the first to fourth color cells in the first pixel pattern is different from the arrangement of the first to fourth color cells in the second pixel pattern, and the first and second pixel patterns are alternately arranged in corresponding columns of the first and second regions.

2. The 3D image display of claim 1, wherein the second color cell and the fourth color cell comprise a same color and in the second pixel pattern the third color cell, the second color cell, the first color cell, and the fourth color cell are sequentially arranged in the second direction.

3. The 3D image display of claim 2, wherein the first and third color cells have a same length in the second direction, the second and fourth color cells have a same length in the second direction, and a ratio of the length of each of the first and third color cells to the length of each of the second and fourth color cells is about 1:

0.5.

4. The 3D image display of claim 2, wherein the first color cell is a red cell, each of the second and fourth color cells is a green cell, and the third color cell is a blue cell.

5. The 3D image display of claim 1, wherein the second color cell and the third color cell have a same color and in the second pixel pattern the fourth color cell, the second color cell, the third color cell, and the first color cell are sequentially arranged in the second direction.

6. The 3D image display of claim 5, wherein the first and fourth color cells have a same length in the second direction, the second and third color cells have a same length in the second direction, and a ratio of the length of each of the first and fourth color cells to the length of each of the second and third color cells is about 1:

0.5.

7. The 3D image display of claim 6, wherein the first color cell is a red cell, each of the second and third color cells is a green cell, and the fourth color cell is a blue cell.

8. The 3D image display of claim 1, wherein the first, second, third, and fourth color cells have different colors from each other and in the second pixel pattern the third color cell, the fourth color cell, the first color cell, and the second color cell are sequentially arranged in the second direction.

9. The 3D image display of claim 8, wherein the first, second, third, and fourth color cells correspond to red, green, blue, and white cells, respectively.

10. The 3D image display of claim 1, wherein the columns of the first region have different viewpoints from each other and the columns of the second region have different viewpoints from each other, wherein the corresponding columns of the first and second regions have a same viewpoint.

11. The 3D image display of claim 1, wherein the first pixel pattern and the second pixel pattern are alternately arranged in the columns of each of the first and second regions.

12. The 3D image display of claim 1, wherein the image converting unit comprises a plurality of lenticular lenses.

13. The 3D image display of claim 12, wherein a first lenticular lens and a second lenticular lens of the lenticular lenses respectively correspond to the first and second regions and each of the first and second lenticular lenses has a lens axis substantially parallel with the second direction.

14. The 3D image display of claim 12, wherein a first lenticular lens and a second lenticular lens of the lenticular lenses are extended in the second direction and arranged in the first direction and each of the first and second lenticular lenses is overlapped with a plurality of the color cells arranged in the first direction.

15. The 3D image display of claim 12, wherein each of a first lenticular lens and a second lenticular lens of the lenticular lenses has a lens axis inclined at a first angle with respect to the second direction.
