Touch display panel and display apparatus

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 comprising a light emitter;

• wherein the touch display panel comprises:
• a substrate;
• a trace, wherein at least part of the trace is in the switching region on the substrate;
• a touch signal line, at a side of the trace away from the substrate;
• a touch connection line, electrically connected to the touch signal line and in a different layer from the trace and the touch signal line;
• wherein in a direction perpendicular to the substrate, the touch connection line overlaps at least part of edges of the trace;
• and
• a dam between the touch signal line and the trace;
• the touch signal line comprises a first signal line portion and a second signal line portion;
• an orthographic projection of the first signal line portion on the substrate is outside the orthographic projection of the trace on the substrate, and an orthographic projection of the second signal line portion on the substrate is within the orthographic projection of the trace on the substrate;
• a boundary of the orthographic projections of the first signal line portion and the second signal line portion on the substrate is within an orthographic projection of the dam on the substrate.

A display apparatus, comprising a touch display panel

• wherein the touch display panel comprises:
• a touch region and a switching region, the touch region and the switching region being adjacent to each other, and the touch region comprising a light emitter;
• a substrate;
• a trace, wherein at least part of the trace is in the switching region on the substrate;
• a touch signal line, at a side of the trace away from the substrate;
• a touch connection line, electrically connected to the touch signal line and in a different layer from the trace and the touch signal line;
• wherein in a direction perpendicular to the substrate, the touch connection line overlaps at least part of edges of the trace;
• wherein the touch connection line comprises a first switching line in the switching region;
• wherein the first switching line comprises a first sub-switching line and a second sub-switching line, the first sub-switching line is between the substrate and the trace, and the second sub-switching line is between the trace and the touch signal line;
• and the touch signal line is electrically connected to the first sub-switching line and the second sub-switching line;
• wherein the trace has hollow portions and the hollow portions are hollow parts of the trace;
• the second sub-switching line is electrically connected to the first sub-switching line and the touch signal line;
• and an orthographic projection of a part of the second sub-switching line in electrical connection with the first sub-switching line on the substrate and an orthographic projection of a part of the second sub-switching line in electrical connection with the touch signal line on the substrate each are within an orthographic projection of a hollow portion of the hollow portions on the substrate and outside the orthographic projection of the trace on the substrate.
