Abstract

A display panel and a display device are provided in the present disclosure. The display panel includes a first display region and a second display region which are adjacently arranged. A light transmittance of the first display region is greater than a light transmittance of the second display region. The display panel further includes a plurality of scan lines and a plurality of data lines extending along the second direction. One first sub-pixel row is electrically connected to at least two of the plurality of scan lines. The plurality of data lines includes first data lines, where one of the first data lines is electrically connected to the first sub-pixel column, and at least a part of the first data lines is made of a transparent conductive material. In the first display region, at least two of the first data lines are connected through a connection line.

a plurality of scan lines extending along the first direction and a plurality of data lines extending along the second direction, wherein:
one first sub-pixel row is electrically connected to at least two of the plurality of scan lines;
the plurality of data lines includes first data lines in the first display region, wherein one of the first data lines is electrically connected to the first sub-pixel column, and at least a part of the first data lines is made of a transparent conductive material; and
in the first display region, at least two of the first data lines do not overlap with each other and are disposed on two opposite sides of one or more sub-pixel columns along the first direction and connected with each other through a connection line, and the at least two first data lines in the first display region are connected with a same second data line in the second display region, and the connection line is disposed between the first display region and the second display region and extends along the first direction.

2. The display panel according to claim 1 , wherein:
the second display region includes a plurality of second pixels arranged in an array; the plurality of second pixels includes a plurality of second sub-pixels with different colors; second sub-pixels arranged along the first direction form a second sub-pixel row; second sub-pixels arranged along the second direction form a second sub-pixel column; and one second sub-pixel row is electrically connected to one of the plurality of scan lines; and
the plurality of data lines further includes second data lines, and one of the second data lines is electrically connected to the second sub-pixel column.

3. The display panel according to claim 2 , wherein:
a material of the connection line is same as a material of the second data lines.

4. The display panel according to claim 1 , wherein:
the at least two of the first data lines, which are connected with each other through the connection line, include a first sub-data line and a second sub-data line; the first sub-pixel column electrically connected to the first sub-data line is an M-th sub-pixel column; and the first sub-pixel column electrically connected to the second sub-data line is an N-th sub-pixel column; and
