Touch structure and touch display panel

A touch display panel, comprising:

• a substrate, a display structure layer disposed on the substrate, and a touch structure layer disposed on the display structure layer, wherein
• the touch structure layer comprises the following touch structure:
• the touch structure comprises a first region and a second region, touch electrodes in the first region are touch electrodes with a flawless contour, and touch electrodes in the second region are touch electrodes with a notched contour;
• the touch electrodes in the first region comprise at least one first boundary electrode which is adjacent to the touch electrodes in the second region and at least one first non-boundary electrode which is not adjacent to the touch electrodes in the second region;
• the touch electrodes in the second region comprise at least one second boundary electrode which is adjacent to the first boundary electrode;
• the first boundary electrode comprises a first side, the first side is adjacent to the second boundary electrode, and the second boundary electrode comprises a second side, the second side is adjacent to the first boundary electrode;
• the first side and the second side are provided respectively with a compensation structure which is configured to form a compensation boundary line between the first side and the second side, a length of the compensation boundary line being greater than a length of a reference boundary line, the reference boundary line is a boundary line formed between one side of a first non-boundary electrode and one side of a touch electrode adjacent to the first non-boundary electrode,
• wherein, a length difference between the length of the compensation boundary line and the length of the reference boundary line is adjusted to make mutual capacitance values and tolerance values of the touch electrodes with the notched contour approaching the same as those of touch electrodes with the flawless contour to enhance uniformity of touch performance;
• and
• the second region is disposed corresponding to any one or more of the following positions in the display structure layer:
• edge region, corner region and mounting hole region.
