1. A display panel, comprising a light emitting layer and a touch structure located above the light emitting layer, wherein
the touch structure comprises a plurality of touch areas and a driving circuit, and each of the touch areas comprises a plurality of touch units;
the plurality of touch units are arranged in a first direction in at least two rows, the plurality of touch units in each of the at least two rows are arranged in a second direction, the plurality of touch units are arranged in at least two columns along the second direction, and the plurality of touch units in each of the at least two columns are arranged along the first direction; and
the driving circuit is located outside the touch areas, wherein
a plurality of first traces are disposed below the touch areas, and the touch units in a same row are electrically connected to the driving circuit through same one of the plurality of first traces corresponding to the row;
the touch units in a same column are electrically connected to the driving circuit through a same second trace corresponding to the column;
wherein the touch units in each of the columns comprise a first end adjacent to the drive circuit and a second end distal from the drive circuit, and a plurality of second traces are led out from the first end; and
wherein each of the touch units comprises:
a first insulating layer having an opening;
a first connecting line located in the opening of the first insulating layer;
a first electrode located on the first connecting line, and is electrically connected to the first connecting line;
a second electrode located on the first insulating layer, and is electrically insulated from the first electrode;
a second insulating layer covering the first electrode, the second electrode, and the first insulating layer, wherein the second insulating layer has a via hole exposing the second electrode;
a second connecting line located on the second insulating layer, and electrically connected to the second electrode through the via hole.
