Abstract

A display panel including sub pixels, a plurality of first and second scan lines, a plurality of first and second data lines, a plurality of first and second auxiliary lines and first conductive vias is provided. The sub pixels are arranged into first rows arranged in a first direction and second rows arranged in a second direction. The second rows are electrically connected to the first and second scan lines in alternation and are electrically connected to the first and second data lines in alternation. Each first auxiliary line includes a first portion electrically connected to a corresponding first scan line and a second portion spaced away from the first portion. The second auxiliary lines are respectively located between two adjacent first rows. Each second scan line is electrically connected to a corresponding first scan line through at least one second auxiliary line.

First claim

What is claimed is:

1. A display panel, comprising:
a plurality of sub-pixels, arranged into a plurality of first rows arranged in a first direction and a plurality of second rows arranged in a second direction intersected with the first direction;
a plurality of first scan lines and a plurality of second scan lines, arranged in alternation in the second direction and respectively electrically connected to the second rows;
a plurality of first data lines and a plurality of second data lines, arranged in alternation in the first direction, wherein there are one first data line and one second data line between any two adjacent first rows, and the second rows are electrically connected to the first data lines and the second data lines in alternation;
a plurality of first auxiliary lines and a plurality of first conductive vias, each of the first auxiliary lines extending in the second direction and comprising a first portion and a second portion arranged in the second direction, wherein the first portion is electrically connected to one corresponding first scan line through at least one first conductive via, and the second portion is spaced apart from the first portion and electrically insulated from the first portion; and
a plurality of second auxiliary lines, respectively located between two adjacent first rows, wherein each of the second auxiliary lines extends from one corresponding first scan line to the adjacent second scan line in the second direction, and each of the second scan lines is electrically connected to one corresponding first scan line through at least one second auxiliary line.

2. The display panel as claimed in claim 1 , wherein each of the first scan lines is electrically connected to one second scan line and two adjacent second rows, and the electrically connected one first scan line and the one second scan line are respectively located at opposite sides of one of the two adjacent second rows, and the one second scan line is located between the two adjacent second rows.

3. The display panel as claimed in claim 1 , wherein the first auxiliary lines, the first data lines, and the second data lines belong to a same conductive layer.

4. The display panel as claimed in claim 1 , wherein an end of the first portion close to the second portion terminates above one corresponding first scan line, and the second portion extends away from the first portion in the second direction from a position close to the end of the first portion.

5. The display panel as claimed in claim 1 , wherein each of the first scan lines and one second scan line electrically connected thereto are electrically connected to the first portion of at least one first auxiliary line, and the first portion of the at least one first auxiliary line is not overlapped with the electrically connected second scan line in a third direction perpendicular to the first direction and the second direction.

6. The display panel as claimed in claim 1 , wherein the first portion is connected to a gate signal end, and the second portion is connected to a direct current signal end.

7. The display panel as claimed in claim 1 , wherein the second auxiliary lines, the first scan lines, and the second scan lines belong to a same conductive layer, and each of the second auxiliary lines is in contact with one electrically connected first scan line and one electrically connected second scan line.

8. The display panel as claimed in claim 1 , wherein the second auxiliary lines do not belong to a same conductive layer as the first scan lines and the second scan lines, and the display panel further comprises:
a plurality of second conductive vias, wherein each of the second auxiliary lines is electrically connected to one corresponding first scan line and one corresponding second scan line through plural of the second conductive vias.

9. The display panel as claimed in claim 1 , wherein there is one or plural of the first rows between each of the second auxiliary lines and one electrically connected first auxiliary line.

10. The display panel as claimed in claim 1 , wherein the second auxiliary lines are arranged in a staggered manner.

11. The display panel as claimed in claim 1 , wherein each of the second scan lines is electrically connected to the one corresponding first scan line through plural of second auxiliary lines.

12. The display panel as claimed in claim 1 , wherein the sub-pixels comprise a plurality of red sub-pixels, a plurality of green sub-pixels, and a plurality of blue sub-pixels, and each of the second auxiliary lines is located between the adjacent red and blue sub-pixels.

13. The display panel as claimed in claim 1 , further comprising:
a plurality of third auxiliary lines, disposed near ends of the first scan lines and the second scan lines, wherein each of the third auxiliary lines extends from one corresponding first scan line to the adjacent second scan line along the second direction, and each of the second scan lines is further electrically connected to the one corresponding first scan line through at least one third auxiliary line.

14. The display panel as claimed in claim 13 , wherein the third auxiliary lines, the first scan lines, and the second scan lines belong to a same conductive layer, and each of the third auxiliary lines is in contact with one electrically connected first scan line and one electrically connected second scan line.

15. The display panel as claimed in claim 13 , wherein the third auxiliary lines do not belong to a same conductive layer as the first scan lines and the second scan lines, and the display panel further comprises:
a plurality of third conductive vias, wherein each of the third auxiliary lines is electrically connected to one corresponding first scan line and one corresponding second scan line through plural of the third conductive vias.

16. The display panel as claimed in claim 1 , further comprising:
a plurality of fourth auxiliary lines, respectively disposed between two adjacent first rows.

17. The display panel as claimed in claim 16 , wherein the fourth auxiliary lines, the first data lines, and the second data lines belong to a same conductive layer.

18. The display panel as claimed in claim 16 , wherein at least one fourth auxiliary line is overlapped with at least one second auxiliary line in a third direction perpendicular to the first direction and the second direction and is electrically insulated from the at least one second auxiliary line.

19. The display panel as claimed in claim 16 , wherein there is one or plural of the first rows between each of the fourth auxiliary lines and the adjacent first auxiliary line.

20. The display panel as claimed in claim 1 , wherein one first data line and one second data line respectively disposed at opposite sides of one of the first rows are overlapped with plural sub-pixels of the one of the first rows in a third direction.
