1. A display panel, comprising:
a base substrate;
a plurality of data signal lines on the base substrate; and
a plurality of pixel units, wherein the plurality of pixel units each has a transparent area and a non-transparent area, and comprises a plurality of sub-pixels in the non-transparent area;
wherein
all sub-pixels of the display panel are arranged in an array;
each column of sub-pixels corresponds to a respective one of the plurality of data signal lines; and
at least part of the plurality of data signal lines being arranged around transparent areas;
wherein the display panel further comprises:
a plurality of fixed voltage signal lines, wherein no fixed voltage signal line is arranged in the transparent areas; and
a plurality of detection signal lines, wherein each column of pixel units corresponds to a respective one of the plurality of detection signal lines; and no detection signal line is arranged in the transparent areas;
wherein the plurality of detection signal lines, the plurality of data signal lines and the plurality of fixed voltage signal lines are located in column gaps between every two adjacent columns of pixel units; and in a same column gap, a detection signal line, data signal lines and a fixed voltage signal line extend in a column direction, and the fixed voltage signal line is located between the detection signal line and the data signal lines.
