Abstract

A display panel includes a first display area having a plurality of first display elements, a second display area having a plurality of second display elements, and a third display area between the first display area and the second display area, wherein the third display area includes a first sub display area adjacent to the second display area in a first direction, and a second sub display area adjacent to the second display area in a second direction, the first sub display area comprises a bypass area, some data lines pass across the first sub display area and the second sub display area, and change their extension direction in the bypass area.

First claim

What is claimed is:

1. A display panel comprising:
a substrate comprising a first display area in which a plurality of first display elements are disposed, a second display area in which a plurality of second display elements are disposed, and a third display area between the first display area and the second display area;
a plurality of first pixel circuits in the first display area and connected to the plurality of first display elements;
a plurality of second pixel circuits in the third display area and connected to the plurality of second display elements; and
a plurality of first data lines connected to the plurality of first pixel circuits of the first display area and the plurality of second pixel circuits of the third display area, wherein
the third display area comprises a first sub display area adjacent to the second display area in a first direction, and a second sub display area adjacent to the second display area in a second direction,
the first sub display area comprises a bypass area, and
the plurality of first data lines pass across the first sub display area and the second sub display area, and an extension direction thereof changes in the bypass area.

2. The display panel of claim 1 , wherein the bypass area extends along the first sub display area in the second direction, and is adjacent to the second sub display area and the second display area.

3. The display panel of claim 1 , further comprising:
a plurality of third display elements and a plurality of third pixel circuits connected to the plurality of third display elements, arranged in the first sub display area of the third display area;
a plurality of fourth display elements and a plurality of fourth pixel circuits connected to the plurality of fourth display elements, arranged in the second sub display area of the third display area; and
a plurality of second data lines connected to the first pixel circuits of the first display area and the fourth pixel circuits of the second sub display area, and of which an extension direction changes in the bypass area of the first sub display area.

4. The display panel of claim 3 , wherein each of the first data lines and the second data lines is connected to the first pixel circuits and the third pixel circuits of the first sub display area, arranged in a same column.

5. The display panel of claim 3 , wherein a size of the third pixel circuits in the first direction is less than a size of the first pixel circuits in the first direction.

6. The display panel of claim 5 , wherein each of the third display elements overlaps a portion of each of the third pixel circuits to which the third display element is connected and a portion of the bypass area.

7. The display panel of claim 6 , wherein one of the first data line and the second data line crossing each other in the bypass area comprises a first portion in the first sub display area and a second portion in the second sub display area, and the first portion is electrically connected to the second portion in the bypass area.

8. The display panel of claim 3 , wherein at least one of the first data lines and at least one of the second data lines cross each other in the bypass area.

9. The display panel of claim 8 , wherein a portion of each of the first data lines and a portion of each of the second data lines that cross each other in the bypass area are on different layers from each other.

10. The display panel of claim 9 , wherein, regarding one of the first data line and the second data line crossing each other in the bypass area, a portion in the first sub display area and a portion in the second sub display area are electrically connected to each other.

11. The display panel of claim 9 , wherein one of the first data line and the second data line crossing each other in the bypass area comprises a first portion in the first sub display area, a second portion in the second sub display area, and a third portion arranged in the bypass area and connecting the first portion and the second portion.

12. A display panel comprising:
a substrate comprising a first display area in which a plurality of first display elements are disposed, a second display area in which a plurality of second display elements are disposed, and a third display area between the first display area and the second display area;
a plurality of first pixel circuits in the first display area and connected to the plurality of first display elements;
a plurality of second pixel circuits in the third display area and connected to the plurality of second display elements; and
a plurality of first data lines connected to the plurality of first pixel circuits of the first display area and the plurality of second pixel circuits of the third display area, wherein
the third display area comprises a pair of first sub display areas spaced apart from each other in a first direction with the second display area therebetween, and a pair of second sub display areas spaced apart from each other in a second direction with the second display area therebetween,
each of the pair of first sub display areas comprises a bypass area, and
the first data lines pass across one of the first sub display areas and the second sub display areas, and an extension direction thereof changes in the bypass area.

13. The display panel of claim 12 , further comprising:
a plurality of third display elements and a plurality of third pixel circuits connected to the third display elements, in the first sub display areas of the third display area;
a plurality of fourth display elements and a plurality of fourth pixel circuits connected to the fourth display elements, in the second sub display areas of the third display area; and
a plurality of second data lines which are connected to the first pixel circuits of the first display area and the fourth pixel circuits of each of the second sub display areas, and of which an extension direction changes in the bypass area of each of the first sub display areas, wherein
each of the first data lines and the second data lines are connected to the first pixel circuits and the third pixel circuits of the first sub display area, in a same column.

14. The display panel of claim 13 , wherein a size of the third pixel circuits in the first direction is less than a size of the first pixel circuits in the first direction.

15. The display panel of claim 13 , wherein at least one of the first data lines and at least one of the second data lines cross each other in the bypass area.

16. The display panel of claim 13 , wherein a portion of each of the first data lines and a portion of each of the second data lines, which cross each other in the bypass area, are on different layers from each other.

17. The display panel of claim 13 , wherein one of the first data line and the second data line crossing each other in the bypass area comprises a first portion and a second portion in each of the pair of first sub display areas, and a connection portion in the second sub display area, and the first portion and the second portion are electrically connected to each other by the connection portion in the bypass area.
