1. A display panel, comprising:
a substrate; and
a touch layer disposed on one side of the substrate and including a touch area of the display panel,
wherein:
the touch layer includes a plurality of first touch units and a plurality of second touch units;
the plurality of first touch units extend in a first direction and are arranged in a second direction;
the plurality of second touch units extend in the second direction and are arranged in the first direction;
the plurality of first touch units include a plurality of first touch electrodes arranged in the first direction and connected with each other in series;
the plurality of the second touch units include a plurality of second touch electrodes arranged in the second direction and connected with each other in series;
the plurality of first touch electrodes are insulated from the plurality of second touch electrodes;
the display panel includes two mounting holes located in the touch area;
the touch layer is hollowed out at positions of the two mounting holes;
the two mounting holes are arranged in the first direction;
a first interval is provided between the two mounting holes;
the touch layer further includes an auxiliary electrode;
the auxiliary electrode includes a first auxiliary electrode located in the first interval;
at least one of the plurality of first touch units is cut off by the two mounting holes;
the first touch unit cut off by the two mounting holes is a first touch unit i arranged in the second direction;
first touch units adjacent to the first touch unit i in the second direction are a first touch unit (i+1) and a first touch unit (i−1), respectively;
the first auxiliary electrode is connected to at least one of the first touch unit (i+1) and the first touch unit (i−1);
or
at least one of the plurality of second touch units is cut off by the two mounting holes;
the second touch unit cut off by the two mounting holes is a second touch unit i arranged in the first direction;
second touch units adjacent to the second touch unit i in the first direction are a second touch unit (i+1) and a second touch unit (i−1), respectively;
the first auxiliary electrode is connected to at least one of the second touch unit (i+1) and the second touch unit (i−1); and
i≥2, and i is an integer;
an area of an orthographic projection of the first auxiliary electrode on the substrate is S0;
the first touch electrode includes a conventional first touch electrode;
an area of an orthographic projection of the conventional first touch electrode on the substrate is S1;
S0<S1; and
the conventional first touch electrode is not adjacent to both of the two mounting holes and an edge of the touch area.
