Touch structure, display panel and display device

A touch structure having a touch region, the touch region including a main touch region and a corner region, the corner region being located around the main touch region;

• the touch structure comprising:
• a plurality of first touch units extending in a first direction, wherein a first touch unit includes a plurality of first touch electrodes and a plurality of first connection portions, a first connection portion is electrically connected to two adjacent first touch electrodes;
• a plurality of second touch units extending in a second direction, wherein a second touch unit includes a plurality of second touch electrodes and a plurality of second connection portions, a second connection portion is electrically connected to two adjacent second touch electrodes;
• the first direction intersects the second direction;
• wherein an orthogonal projection of the first connection portion on a reference surface intersects an orthogonal projection of the second connection portion on the reference surface, the first connection portion and the second connection portion, whose orthogonal projections on the reference surface intersect each other, constitute a connection unit;
• at least one of a plurality of connection units composed of the plurality of first connection portions and the plurality of second connection portions is an adjustment connection unit, and the adjustment connection unit is located in the corner region;
• in a first touch unit in which a first connection portion of the adjustment connection unit is located, a straight line passing through centers of at least two first touch electrodes located in the main touch region is a first reference line;
• in a second touch unit in which a second connection portion of the adjustment connection unit is located, a straight line passing through centers of at least two second touch electrodes located in the main touch region is a second reference line;
• an intersection point of the first reference line and the second reference line is a reference point;
• and
• the reference point is located outside the corner region, and is located farther away from a center of the main touch region than the adjustment connection unit;
• wherein the plurality of first touch units and the plurality of second touch units intersect one another to constitute a plurality of capacitive units;
• the plurality of capacitive units are arranged in a plurality of rows in the first direction, and arranged in a plurality of columns in the second direction;
• a capacitive unit includes a single connection unit, opposite portions of two first touch electrodes connected to a first connection portion of the single connection unit, and opposite portions of two second touch electrodes connected to a second connection portion of the single connection unit;
• a capacitive unit including the adjustment connection unit is a compensation capacitive unit, a capacitive unit located in a same row with and adjacent to the compensation capacitive unit is a first capacitive unit, a capacitive unit located in a same column with and adjacent to the compensation capacitive unit is a second capacitive unit;
• the compensation capacitive unit, the first capacitive unit and the second capacitive unit are all located in the corner region;
• and
• an area of the first capacitive unit and an area of the second capacitive unit are each larger than an area of the compensation capacitive unit, and are each smaller than an area of a capacitive unit located in the main touch region.
