Pixel arrangement of an organic light emitting display device

1. A pixel arrangement of an organic light emitting display device with a plurality of repeatedly arranged sub-pixel groups, each of the sub-pixel groups comprising:

two first sub-pixels in i-th and (i+2)-th columns (i is a natural number);

two second sub-pixels in the i-th and (i+2)-th columns, the second sub-pixels being arranged in different rows with respect to the first sub-pixels; and

two third sub-pixels in (i+1)-th and (i+3)-th columns, each third sub-pixel overlapping at least two adjacent rows of the first and second sub-pixels,

wherein the (i+1)-th and (i+3)-th columns include only the third sub-pixels,

wherein the third sub-pixel is at least two times longer than the first sub-pixel along a column direction, and

wherein the first sub-pixels and the second sub-pixels are alternately arranged in a same column and are alternately arranged in a same row, the i-th and (i+2)-th columns including only the first and second sub-pixels.

2. The pixel arrangement of the organic light emitting display device as claimed in claim 1 , wherein the third sub-pixel is wider than the first sub-pixel.

3. The pixel arrangement of the organic light emitting display device as claimed in claim 1 , wherein the third sub-pixel is a blue sub-pixel, the first sub-pixel is a red sub-pixel, and the second sub-pixel is a green sub-pixel.

4. The pixel arrangement of the organic light emitting display device as claimed in claim 1 , wherein the first sub-pixels and the second sub-pixels are arranged in separate adjacent rows.

5. A pixel arrangement of an organic light emitting display device, comprising:

first and second sub-pixels arranged alternately in a plurality of columns, the first and second sub-pixels being configured to emit different colors; and

third sub-pixels between adjacent columns of alternating first and second sub-pixels, each third sub-pixel overlapping four alternating first and second sub-pixels within a same column.

6. The pixel arrangement of the organic light emitting display device as claimed in claim 5 , wherein third sub-pixels in adjacent columns overlap only partially.

7. The pixel arrangement of the organic light emitting display device as claimed in claim 6 , wherein each third sub-pixel overlaps a portion of a third sub-pixel in an adjacent column that correspond to two alternating first and second sub-pixels within a same column.

8. The pixel arrangement of the organic light emitting display device as claimed in claim 5 , wherein the third sub-pixel is wider than the first sub-pixel.

9. The pixel arrangement of the organic light emitting display device as claimed in claim 5 , wherein the third sub-pixel is set up as a sub-pixel with the shortest life property among a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

10. The pixel arrangement of the organic light emitting display device as claimed in claim 5 , wherein the third sub-pixel is a blue sub-pixel, the first sub-pixel is a red sub-pixel, and the second sub-pixel is a green sub-pixel.

11. The pixel arrangement of the organic light emitting display device as claimed in claim 5 , wherein the first sub-pixels and the second sub-pixels are alternately arranged in a same row.

12. The pixel arrangement of the organic light emitting display device as claimed in claim 5 , wherein the first sub-pixels and the second sub-pixels are arranged in separate rows adjacent to each other.

13. The pixel arrangement of the organic light emitting display device as claimed in claim 1 , wherein the third sub-pixels are blue.

14. The pixel arrangement of the organic light emitting display device as claimed in claim 1 , wherein the first sub-pixels are of a same color, the second sub-pixels are of a same color different than the color of the first sub-pixels, and the third sub-pixels are of a same color different than the color of each of the first and second sub-pixels.

15. The pixel arrangement of the organic light emitting display device as claimed in claim 1 , wherein the third sub-pixel has a larger area than either of the first and second sub-pixels.

16. The pixel arrangement of the organic light emitting display device as claimed in claim 1 , wherein the third sub-pixel is a sub-pixel with a shortest life among the first through third sub-pixels.
