1. A touch display panel, comprising:
a base substrate;
a plurality of display signal lines on one side of the base substrate;
a plurality of light-emitting devices arranged in an array on a side of the plurality of display signal lines away from the base substrate;
a touch structure on a side of the plurality of light-emitting devices away from the base substrate; and
a shielding layer between the plurality of display signal lines and the plurality of light-emitting devices, wherein an orthographic projection of the shielding layer on the base substrate covers at least a part of an orthographic projection of the plurality of display signal lines on the base substrate;
wherein the touch display panel comprises a display region and a frame region around the display region; the touch display panel further comprises: a high voltage power line in the display region and extending to the frame region, and a low voltage power line in the frame region; and
the touch display panel further comprises a first conductive connection part and a second conductive connection part arranged independent from each other in the frame region and in a same layer as the shielding layer; the first conductive connection part is electrically connected to the high voltage power line, and the second conductive connection part is electrically connected to the low voltage power line.
