Abstract
The present disclosure provides a touch panel structure and a flexible touch display device. The touch panel structure includes a plurality of first touch electrode chains and a plurality of second touch electrode chains insulated from and in cross-connection with the first touch electrode chains; each of the first touch electrode chains includes a plurality of spaced-apart first touch electrodes, and the adjacent two of the first touch electrodes are electrically connected through the first connecting portion, the first connecting portion includes at least two conductive bridges; two adjacent second touch electrodes are electrically connected through a second connecting portion, and the first connecting portion is stacked on the second connecting portion and insulated from the second connecting portion. The touch panel structure can not only increase the contact area between the first connection portion and the corresponding touch electrode but also reduce the contact resistance.
