Touch-control display panel and preparation method therefor, and touch-control display apparatus

A touch display panel comprising a substrate, a first metal layer disposed on the substrate, an insulating layer disposed at a side of the first metal layer away from the substrate, and a second metal layer disposed at a side of the insulating layer away from the first metal layer, wherein:

• one of the first metal layer and the second metal layer comprises a plurality of connection bridges, and the other of the first metal layer and the second metal layer comprises a first electrode, a second electrode and a through via, the first electrode comprises a plurality of first sub-electrodes arranged along a first direction, and adjacent first sub-electrodes are bridged by a connection bridge;
• the second electrode comprises a plurality of second sub-electrodes arranged along a second direction, and two adjacent second sub-electrodes along the second direction are connected with each other;
• the through via penetrates through the first sub-electrodes and the second sub-electrodes;
• and
• at least one of the first metal layer and the second metal layer further comprises a compensation electrode surrounding the through via, wherein the compensation electrode comprises a first compensation electrode and a second compensation electrode;
• a surface of the first compensation electrode adjacent to the second compensation electrode is a first end surface;
• a surface of the second compensation electrode adjacent to the first compensation electrode is a second end surface;
• a structure of the first end surface is complementary to a structure of the second end surface;
• and a length of an outer contour of the first end surface is greater than a thickness of the first compensation electrode along a centerline direction of the through via;
• wherein the first end surface comprises one or more first protrusions, and the second end surface comprises one or more second protrusions, and the one or more first protrusions and the one or more second protrusions are arranged at intervals;
• wherein there is an overlap region between an orthographic projection of the one or more first protrusions of the first end surface of the first compensation electrode on the substrate and an orthographic projection of the second compensation electrode on the substrate, and there is an overlap region between an orthographic projection of the one or more second protrusions of the second end surface of the second compensation electrode on the substrate and an orthographic projection of the first compensation electrode on the substrate.
