Abstract

A display panel may include the following elements: a substrate including an opening area, a display area surrounding the opening area, and a first non-display area between the opening area and the display area; a data line positioned at a first side relative to the opening area; a first scan line; a second scan line; a first pixel connected to the data line and the first scan line; a second pixel connected to the data line and the second scan line; a first emission control line connected to the first pixel; a connecting section positioned on the first non-display area; a second emission control line connected to the second pixel and connected through the connecting section to the first emission control line; and an emission control driver configured to simultaneously provide emission control signals to the first emission control line and the second emission control line.

First claim

What is claimed is:

1. A display panel comprising:
a substrate including an opening area, a display area surrounding at least a part of the opening area, a first non-display area between the opening area and the display area, and a second non-display area outside the display area;
a first data line positioned at a first side relative to the opening area in a plan view of the display panel;
a second data line positioned at a second side relative to the opening area in the plan view of the display panel, wherein the opening area is positioned between the first data line and the second data line;
a first scan line;
a second scan line;
a first pixel electrically connected to each of the first data line and the first scan line;
a second pixel electrically connected to each of the first data line and the second scan line;
a third pixel electrically connected to each of the second data line and the first scan line; and
a fourth pixel electrically connected to each of the second data line and the second scan line,
a first emission control line electrically connected to the first pixel;
a first connecting section positioned on the first non-display area;
a second emission control line electrically connected to the second pixel and electrically connected through the first connecting section to the first emission control line;
a first opposite emission control line electrically connected to the third pixel;
a first opposite connecting section positioned opposite the first connecting section and positioned on the first non-display area; and
a second opposite emission control line electrically connected to the fourth pixel and electrically connected through the first opposite connecting section to the first opposite emission control line.

2. The display panel of claim 1 , further comprising:
a first emission control detour section electrically connecting the second emission control line and the second opposite emission control line, and wherein the first emission control detour section bypasses the opening area.

3. The display panel of claim 2 , further comprising:
a third data line, which includes a first data detour section, the first data detour section bypassing the opening area and being positioned on the first non-display area; and
a fourth data line, which includes a second data detour section, the second data detours section bypassing the opening area and being positioned on the first non-display area,
wherein the first emission control detour section is arranged between the first data detour section and a second data detour section.

4. The display panel of claim 2 , further comprising:
a first insulating layer having a first contact hole,
wherein the second emission control line further comprises a first pixel-connecting section, and wherein the first emission control detour section is connected to the first pixel-connecting section through the first contact hole and is electrically connected to the second pixel through the first pixel-connecting section.

5. The display panel of claim 4 , further comprising: a second insulating layer having a second contact hole, and wherein the first emission control detour section is connected to the first pixel-connecting section through the first contact hole and the second contact hole.

6. The display panel of claim 2 , further comprising:
a first insulating layer having a first contact hole,
wherein the second opposite emission control line further comprises a first opposite pixel-connecting section, and wherein the first opposite emission control detour section is connected to the first pixel-connecting section through the first contact hole and is electrically connected to the second pixel through the third pixel-connecting section.

7. The display panel of claim 2 , further comprising: a first insulating layer, wherein the second emission control line further comprises a first pixel-connecting section, and wherein the first emission control detour section is electrically connected to the second pixel through the first pixel-connecting section, and wherein the first emission control detour section and the first pixel-connecting section directly contact a same face of the first insulating layer.

8. The display panel of claim 7 , wherein a material of the first emission control detour section is identical to a material of the first pixel-connecting section.

9. The display panel of claim 2 , further comprising: a first insulating layer, wherein the second opposite emission control line further comprises a first opposite pixel-connecting section, and wherein the first emission control detour section is electrically connected to the fourth pixel through the first pixel-connecting section, and wherein the first emission control detour section and the first pixel-connecting section directly contact a same face of the first insulating layer.

10. The display panel of claim 9 , wherein a material of the first emission control detour section is identical to a material of the first opposite pixel-connecting section.

11. The display panel of claim 2 , further comprising:
a first emission control driver positioned on the second non-display area; and
a second emission control driver positioned on the second non-display area and separated from the first emission control driver,
wherein the first emission control driver is electrically connected to four adjacent emission control lines positioned at the first side relative to the opening display area, and wherein the second emission control driver is electrically connected to four adjacent opposite emission control lines positioned at the second side relative to the opening area.

12. The display panel of claim 1 , wherein the second emission control line and the second opposite emission control line are electrically disconnected from each other.

13. The display panel of claim 12 , wherein the first emission control line and the first opposite emission control line directly contact a same surface of an insulating layer, and wherein a material of the first emission control line is identical to a material of the first opposite emission control line.

14. The display panel of claim 12 , further comprising:
a first emission control driver positioned on the second non-display area and configured to simultaneously provide signals to the first emission control line and the second emission control line; and
a second emission control driver positioned on the second non-display area and configured to simultaneously supply signals to the first opposite emission control line and the second opposite emission control line.

15. The display panel of claim 12 , wherein each of the first connecting section and the first opposite connecting section conforms to an arc of a geometric circle, and wherein the geometric circle is concentric with a perimeter the opening area in the plan view of the display panel.

16. The display panel of claim 1 , further comprising:
