1. A touch display panel, comprising a touch region and a switching region, the touch region and the switching region being adjacent to each other, and the touch region being provided with a light emitter;
wherein the touch display panel comprises:
a substrate;
a trace, wherein at least part of the trace is located in the switching region on the substrate;
a touch signal line, located at a side of the trace away from the substrate;
a touch connection line, electrically connected to the touch signal line, and disposed in a different layer from the trace and the touch signal line; wherein in a direction perpendicular to the substrate, the touch connection line is overlapped with at least partial edge of the trace;
wherein the touch connection line comprises a first switching line located in the switching region and located between the substrate and the trace;
hollow portions are disposed on the trace and the hollow portions are hollow parts of the trace; the first switching line is electrically connected to the touch signal line, and a projection of a part of the first switching line in electrical connection with the touch signal line on the substrate is located within a projection of a hollow portion of the hollow portions on the substrate.
