Touch panel structure and flexible touch display device

A touch panel structure, comprising:

• a plurality of first touch electrode chains, wherein the plurality of the first touch electrode chains are arranged at intervals, each of the first touch electrode chains comprises a plurality of spaced first touch electrodes, two adjacent first touch electrodes are electrically connected by a first connecting portion, and the first connecting portion comprises at least two conductive bridges;
• a plurality of second touch electrode chains, wherein the plurality of the second touch electrode chains are arranged at intervals, the second touch electrode chains are cross-insulated from the first touch electrode chains;
• each of the second touch electrode chains comprises a plurality of spaced second touch electrodes, two adjacent second touch electrodes are electrically connected through a second connecting portion, the first connecting portion is stacked on the second connecting portion and insulated from the second connecting portion;
• wherein an insulating block is provided between the second connecting portion and the first connecting portion stacked on the second connecting portion;
• two ends of each of the conductive bridges respectively contact with the two adjacent first touch electrodes through a via hole passing through the insulating block;
• wherein each of the conductive bridges is provided with a plurality of middle openings;
• wherein each of the via holes on a same side of the first connecting portion is not on a same straight line parallel to the second touch electrode chain;
• wherein the second connecting portion extends from the second touch electrode itself;
• wherein the at least two conductive bridges are parallel to each other, and two adjacent conductive bridges are connected by a connecting strap.
