Abstract

A display device includes a first display region, a second display region, a first lens, and a second lens. The first display region includes a first pixel subset and may display a first image. The first image includes a first sub-image corresponding to the first pixel subset and smaller than the first image. The second display region neighbors the first display region, includes a second pixel subset, and may display a second image. The second image includes a second sub-image corresponding to the second pixel subset and smaller than the second image. The second pixel subset is not identical to the first pixel subset. The first lens may show the first sub-image without providing the entire first image. The second lens may show the second sub-image without providing the entire second image when the first lens shows the first sub-image.

First claim

What is claimed is:

1. A display device comprising:
a display panel including a first displaying region and a second displaying region adjacent to the first displaying region;
a timing controller configured to receive first image data corresponding to the first displaying region and second image data corresponding to the second displaying region and to generate converted data by changing orders of line data included in the second image data; and
a data driver configured to generate data signals based on the converted data and to provide the data signals to the display panel,
wherein the timing controller maps a line data set corresponding to a corresponding first type pixel column of the second displaying region to a neighboring first type pixel column of the second displaying region, and
wherein no intervening first type pixel column is positioned between the corresponding first type pixel and the neighboring first type pixel column.

2. The display device of claim 1 , wherein the first displaying region corresponds to a left eye of a user, and
wherein the second displaying region corresponds to a right eye of the user.

3. The display device of claim 1 , wherein the timing controller generates the converted data by maintaining orders of line data included in the first image data corresponding to the first displaying region.

4. The display device of claim 1 , wherein the second displaying region includes first type pixel columns and second type pixel columns arranged alternately, and
wherein the timing controller generates the converted data by remapping first line data corresponding to the first type pixel columns in a first direction.

5. The display device of claim 4 , wherein the first type pixel columns include a first pixel emitting a light with a first color, and
wherein the second type pixel columns include a second pixel emitting a light with a second color.

6. The display device of claim 5 , wherein the first type pixel columns further include a third pixel emitting a light with a third color.

7. The display device of claim 4 , wherein the timing controller maps a kth line data corresponding to a kth pixel column to a k+1th pixel column adjacent to the kth pixel column, where k is a positive integer, and
wherein the kth pixel column and the k+1th pixel column are included in the first type pixel columns.

8. The display device of claim 4 , wherein the timing controller maps a kth line data corresponding to a kth pixel column to a k−1th pixel column adjacent to the kth pixel column, where k is a positive integer, and
wherein the kth pixel column and the k−1th pixel column are included in the first type pixel columns.

9. The display device of claim 1 , wherein the display panel includes pixels arranged in Pentile format, and
wherein the timing controller includes a first sub-pixel rendering filter and a second sub-pixel rendering filter and generates the converted data by applying the second sub-pixel rendering filter to the second image data.

10. The display device of claim 9 , wherein the second image data includes first sub-data and second sub-data, and
wherein the timing controller applies the second sub-pixel rendering filter to the first sub-data.

11. The display device of claim 10 , wherein the second sub-pixel rendering filter has weights for a first adjacent pixel and a second adjacent pixel,
wherein the first adjacent pixel is adjacent to a target pixel, and
wherein the second adjacent pixel is adjacent to the first adjacent pixel.

12. The display device of claim 9 , wherein the timing controller generates the converted data by applying the first sub-pixel rendering filter to first image data corresponding to the first displaying region, and
wherein the first sub-pixel rendering filter is different from the second sub-pixel rendering filter.

13. The display device of claim 12 , wherein the first sub-pixel rendering filter has weights for a target pixel and a first adjacent pixel,
wherein the first adjacent pixel is adjacent to the target pixel.

14. The display device of claim 1 , wherein the display panel includes pixels arranged in Pentile format, and
wherein the timing controller generates the converted data by applying a third sub-pixel rendering filter to the second image data.

15. The display device of claim 14 , wherein the second image data includes first sub-data and second sub-data, and
wherein the timing controller applies the third sub-pixel rendering filter to the second sub-data.

16. The display device of claim 15 , wherein the third sub-pixel rendering filter has a weight for a third adjacent pixel,
wherein the third adjacent pixel is adjacent to a target pixel.

17. A display device comprising:
a first display panel having a first pixel arrangement;
a second display panel adjacent to the first display panel and having a second pixel arrangement different from the first pixel arrangement;
a timing controller configured to generate first converted data corresponding to the first display panel based on stereoscopic image data and to generate second converted data corresponding to the second display panel based on the stereoscopic image data; and
a data driver configured to generate data signals based on the first converted data and the second converted data and to provide the data signals to the first display panel and the second display panel,
wherein no intervening display panel is positioned between the first display panel and the second display panel,
wherein the uppermost leftmost pixel of the first display panel displays a first color, and
wherein the uppermost leftmost pixel of the second display panel displays a second color different from the first color.

18. The display device of claim 17 , wherein the second pixel arrangement is opposite to the first pixel arrangement.

19. A display device comprising:
a display panel including a first displaying region and a second displaying region adjacent to the first displaying region; and
a data driver configured to receive first image data corresponding to the first displaying region and second image data corresponding to the second displaying region, to generate first line data signals based on first line data included in the first image data, to generate second line data signals by applying a sub-pixel rendering filter to second line data included in second image data, and to provide the second line data signals to the display panel,
wherein the display panel includes pixels arranged in Pentile format.

20. The display device of claim 19 , wherein the data driver shifts at least a portion of the second line data in a first direction.
