1. A touch display panel, comprising: a display region and a non-display region, wherein the non-display region comprises a lower bezel region, the lower bezel region comprises a first region and an ink region, the first region is disposed on a side of the ink region facing towards the display region, and wherein the touch display panel comprises:
a substrate;
a display function layer comprising all of an array layer, a light-emitting function layer, and an encapsulation layer disposed on the substrate;
a touch function layer disposed on a side of the display function layer away from the substrate, wherein the touch function layer comprises first touch wirings and second touch wirings disposed at a different layer than the first touch wirings, and the first region is provided with the first touch wirings and the second touch wirings; and
a color filter layer disposed on a side of the touch function layer away from the substrate, wherein the color filter layer comprises black matrixes arranged at intervals, and the first region is covered with the black matrixes;
wherein the touch function layer is further provided with compensation wirings, the compensation wirings are disposed in the first region, and a wiring density percentage of the touch function layer in the first region is in a range of 60% to 90%;
wherein the touch display panel further comprises: a plurality of regions disposed around the first region, wherein a difference between a wiring density percentage of the touch function layer in each of the plurality of regions and the wiring density percentage of the touch function layer in the first region is smaller than 30%, wiring density percentages of the touch function layer in the plurality of regions are in a range of 60% to 90% and are not equal to each other, and the wiring density percentage of the touch function layer in the first region is equal to an average value of the wiring density percentages of the touch function layer in the plurality of regions; and
wherein the wiring density percentage of the touch function layer in the first region is a total wiring area of the first region/a total available area of the first region, and the wiring density percentage of the touch function layer in each of the plurality of regions is a total wiring area of the each of the plurality of regions/a total available area of the each of the plurality of regions.
