1. A touch display panel, comprising:
a display substrate and a touch layer; wherein the display substrate comprises a display region and a non-display region surrounding the display region; and
the touch layer comprises a plurality of touch units and a plurality of touch lines; wherein the plurality of touch units are arranged in an array on the display substrate and at least partially disposed in the display region;
the plurality of touch lines are disposed on the display substrate, and each touch line of the plurality of touch lines is connected to at least one of the plurality of touch units and configured to electrically connect a touch unit connected thereto to a touch integrated circuit;
the plurality of touch lines at least comprise a first trace and a second trace which are disposed in the non-display region, a length of the first trace being greater than a length of the second trace, a cross-sectional area of the first trace being larger than a cross-sectional area of the second trace; and
the display substrate comprises a conductive layer disposed in the non-display region; wherein a first through hole and a second through hole are defined in the conductive layer, the first through hole being within an orthographic projection of the first trace on the conductive layer, the second through hole being within an orthographic projection of the second trace on the conductive layer, and a total opening area of the first through hole in per unit area of the first trace being greater than a total opening area of the second through hole in per unit area of the second trace.
