Abstract

Dot inversion schemes are disclosed on novel display panel layouts with extra drivers. A display panel comprises substantially a set of a subpixel repeating group comprising a pattern of six columns and two rows:

RRGBBGBBGRRG
wherein at least one set of adjacent column subpixels share image data from a single driver upon the display panel.

Claims

1. A display panel comprising substantially a set of a subpixel repeating group comprising a pattern of six columns and two rows:

2. The display panel of claim 1, wherein the single driver connects to two column lines through an interconnect.

3. The display panel of claim 1, wherein the subpixels are sized substantially the same as RGB striped subpixels.

4. The display panel of claim 1, wherein the adjacent columns across the display panel comprise R R and B B subpixels that share image data via an interconnection from a single driver.

5. The display panel of claim 1, wherein the at least one set of adjacent columns comprise R R and B B subpixels that are driven separately by at least two drivers.

6. The display panel of claim 5, wherein subpixel regions to either side of the at least one set of adjacent columns have different polarities for same colored subpixels.

7. A display panel comprising substantially a first set of a first subpixel repeating group comprising at least an even number of subpixels in a first direction wherein said panel further comprises at least one of a second set of a second subpixel repeating group formed on the display panel, said second subpixel repeating group comprising an odd-number of columns of subpixels and further wherein said second subpixel repeating group is adjacent to said first subpixel repeating group;

wherein said first subpixel repeating group comprises the pattern;

8. In a display panel comprising substantially a set of a subpixel repeating group that comprises a pattern of six columns and two rows:

9. The method of claim 8, further comprising:

connecting the single driver to two column lines through an interconnect.

10. The method of claim 8, wherein the subpixels are sized substantially the same as RGB striped subpixels.

11. The method of claim 8, further comprising:

driving adjacent columns across the display panel comprising R R and B B subpixels with image data via an interconnection from a single driver.

12. The method of claim 8, further comprising:

driving at least one set of adjacent columns comprising R R and B B subpixels separately by at least two drivers.

13. The method of claim 12, further comprising:

applying different polarities for same colored subpixels in subpixel regions to either side of the at least one set of adjacent columns.

14. A display panel comprising:

at least one driver; and

substantially a set of a subpixel repeating group comprising a pattern of six columns and two rows;

15. The display panel of claim 14, further comprising:

an extra driver assigned to at least one of double red and double blue subpixel columns of the repeating group.

16. The display of claim 15, wherein subpixels on adjacent sides with respect to the extra driver have different polarities.

17. The display of claim 14, wherein one of the red and blue subpixel columns is split into first and second subpixel components.

18. The display of claim 17, further comprising:

an extra driver assigned to the split subpixel columns.

19. The display of claim 14, further comprising:

an extra driver connected to a column line such that the column line acts as a dummy line.
