Claim 0:
1. A touch display panel, comprising a substrate, and a touch display region and a peripheral region located on the substrate, the touch display region comprising a touch electrode, a through hole penetrating the touch electrode, a through hole detection region surrounding the through hole and a transition connection region located between the through hole detection region and the peripheral region, wherein:
the through hole detection region comprises an annular crack detection line and an annular isolation line, the transition connection region comprises a transition crack detection line and a transition isolation line, the peripheral region comprises an edge crack detection line and an edge isolation line, the annular crack detection line is electrically connected to the edge crack detection line by means of the transition crack detection line, and the annular isolation line is electrically connected to the edge isolation line by means of the transition isolation line, and the edge isolation line is electrically connected to a touch integrated circuit (IC) to input a shielding signal;
an orthographic projection of the edge isolation line on the substrate is located between an orthographic projection of the touch electrode on the substrate and an orthographic projection of the edge crack detection line on the substrate;
an orthographic projection of the transition isolation line on the substrate is located between an orthographic projection of the transition crack detection line on the substrate and the orthographic projection of the touch electrode on the substrate; and
an orthographic projection of the annular crack detection line on the substrate is a first annular shape, an orthographic projection of the annular isolation line on the substrate is a second annular shape, and a side of the first annular shape close to the second annular shape is within a range of a side of the second annular shape close to the first annular shape.
