Abstract

A display panel has functional component regions arranged along a first direction and a display region at least partially surrounding the functional component regions. The display panel includes first signal lines located in the display region. One of the first signal lines has a least one part extending in the first direction, and the first signal lines are arranged in a second direction intersecting with the first direction. The first signal lines include a first-type signal line and a second-type signal line, and the first-type signal line at least partially surrounds the functional component regions. In the first direction, at least one second-type signal line is broken at two sides of one of the functional component region.

first signal lines located in the display region, wherein at least part of each first signal line of the first signal lines extends in a first direction, and the first signal lines are arranged in a second direction intersecting with the first direction,
wherein the first signal lines comprise at least one first-type signal line and at least one second-type signal line, wherein one of the at least one first-type signal line at least partially surrounds the at least two functional component regions, and at least one of the at least one second-type signal line is broken at two sides of one functional component region of the at least two functional component regions in the first direction;
wherein the display panel has a dummy line extending in the second direction and comprises a first edge and a second edge that are opposite to each other in the first direction, wherein a distance d 1 between the first edge and the dummy line and a distance d 2 between the second edge and the dummy line satisfy 0.9≤d1/d2≤1.1, and
wherein the at least two functional component regions comprise a first functional component region and a second functional component region, wherein the dummy line passes through the first functional component region, and one of the at least one second-type signal line is broken at two sides of the first functional component region in the first direction.

2. The display panel according to claim 1 , wherein the at least two functional component regions comprise a first functional component region and a second functional component region, wherein a distance A between the first functional component region and an edge of the display region in the first direction and a length B of the display region in the first direction satisfy B/4≤A≤B/2, and
wherein one of the at least one second-type signal line is broken at two sides of the first functional component region in the first direction.

3. The display panel according to claim 1 , wherein the at least two functional component regions comprise a first functional component region and a second functional component region, wherein a length of the first functional component region in the first direction is greater than a length of the second functional component region in the first direction, and one of the at least one second-type signal line is broken at two sides of the first functional component region in the first direction.

4. The display panel according to claim 1 , wherein at least one first signal line of the first signal lines comprises at least one first connecting line, wherein one of the at least one first connecting line electrically connects two parts, which are located at two sides of one functional component region of the at least two functional component regions, of one first signal line of the first signal lines.

5.
