Abstract

A display device including a plurality sub-pixel groups is disclosed. Each of the plurality sub-pixel groups includes a first sub-pixel, locating at a first column, a first row and a second row adjacent to the first row; a second sub-pixel, locating at a second column adjacent to the first column, the first row and the second row; a third sub-pixel locating at a third column adjacent to the second column and a first row; and a fourth sub-pixel locating at the third column and the second row.

First claim

What is claimed is:

1. A display device, comprising a plurality of sub-pixel groups having the same sub-pixel pattern, wherein the plurality sub-pixel groups comprise a first sub-pixel group, at least one second sub-pixel group located at the same columns as the first sub-pixel group and at least one third sub-pixel group located at the same rows as the first sub-pixel group, and the first sub-pixel group comprises:
a first sub-pixel, locating at a first column, a first row and a second row next to the first row;
a second sub-pixel, locating at a second column next to the first column, a third column next to the second column, and the first row;
a third sub-pixel, locating at the second column, the third column and the second row;
a fourth sub-pixel, locating at a fourth column next to the third column, the first row and the second row;
a fifth sub-pixel, locating at a fifth column next to the fourth column, the first row and the second row;
a six sub-pixel, locating at a sixth column next to the fifth column, the first row and the second row; and
a seventh sub-pixel, locating at a seventh column next to the sixth column, the first row and the second row.

2. The display device of claim 1 , wherein the first sub-pixel, the second sub-pixel, the third sub-pixel, the fourth sub-pixel, the fifth sub-pixel, the sixth sub-pixel and the seventh sub-pixel are corresponding to at least three colors.

3. The display device of claim 1 , wherein the first sub-pixel, the second sub-pixel, the third sub-pixel, the fourth sub-pixel, the fifth sub-pixel, the sixth sub-pixel and the seventh sub-pixel are corresponding to four colors comprising white.

4. The display device of claim 1 , wherein the first sub-pixel, the second sub-pixel, the third sub-pixel, the fourth sub-pixel, the fifth sub-pixel, the sixth sub-pixel and the seventh sub-pixel are corresponding to four colors comprising yellow.

5. The display device of claim 1 , wherein the first sub-pixel, the second sub-pixel and the third sub-pixel are corresponding to a first pixel; the second sub-pixel, the third sub-pixel and the fourth sub-pixel are corresponding to a second pixel; the fourth sub-pixel, the fifth sub-pixel and the sixth sub-pixel corresponds to a third pixel; and the sixth sub-pixel, the seventh sub-pixel and a first sub-pixel of the second sub-pixel group are corresponding to a fourth pixel.

6. The display device of claim 1 , wherein the first sub-pixel group and the at least one third sub-pixel group have different color arrangements.

7. A driving module for a display device comprising a plurality of sub-pixel groups having the same sub-pixel pattern, wherein the plurality sub-pixel groups comprise a first sub-pixel group, at least one second sub-pixel group located at the same columns as the first sub-pixel group and at least one third sub-pixel group located at the same rows as the first sub-pixel group, and the first sub-pixel group comprises a first sub-pixel, locating at a first column, a first row and a second row next to the first row; a second sub-pixel, locating at a second column next to the first column, a third column next to the second column, and the first row; a third sub-pixel, locating at the second column, the third column and the second row; a fourth sub-pixel, locating at a fourth column next to the third column, the first row and the second row; a fifth sub-pixel, locating at a fifth column next to the fourth column, the first row and the second row; a six sub-pixel, locating at a sixth column next to the fifth column, the first row and the second row; and a seventh sub-pixel, locating at a seventh column next to the sixth column, the first row and the second row.

8. The driving module of claim 7 , comprising:
a row driving unit, for driving a plurality of scan lines, wherein the first sub-pixel, the second sub-pixel, the fourth sub-pixel, the fifth sub-pixel, the sixth sub-pixel and the seventh sub-pixel are coupled to a first scan line of the plurality of scan lines and the second sub-pixel are coupled to a second scan line next to the first scan line; and
a column driving unit, for driving a plurality of data lines, wherein the first sub-pixel is coupled to a first data line of the plurality of data lines, the second sub-pixel is coupled to a second data line next to the first data line, the third sub-pixel is coupled to a third data line next to the second data line, the fourth sub-pixel is coupled to a fourth data line next to the third data line, the fifth sub-pixel is coupled to a fifth data line next to the fourth data line, the sixth sub-pixel is coupled to a sixth data line next to the fifth data line, and the seventh sub-pixel is coupled to a seventh data line next to the sixth data line.

9. A display device, comprising a plurality of sub-pixel groups having the same sub-pixel pattern, wherein the plurality sub-pixel groups comprise a first sub-pixel group, at least one second sub-pixel group located at the same columns as the first sub-pixel group and at least one third sub-pixel group located at the same rows as the first sub-pixel group, and the first sub-pixel group comprises:
a first sub-pixel, locating at a first column, a first row and a second row next to the first row;
a second sub-pixel, locating at a second column next to the first column, a third column next to the second column, and the first row;
a third sub-pixel, locating at the second column, the third column and the second row;
a fourth sub-pixel, locating at a fourth column next to the third column, the first row and the second row;
a fifth sub-pixel, locating at a fifth column next to the fourth column, the first row and the second row;
a six sub-pixel, locating at a sixth column next to the fifth column, the first row and the second row; and
a seventh sub-pixel, locating at a seventh column next to the sixth column, the first row and the second row;
