Abstract:
In general, embodiments of the present invention provide systems and methods for a touch display panel and a touch display device including a touch display panel. The touch display panel includes: a substrate, and a common electrode layer located on the substrate. The common electrode layer includes multiple touch electrodes insulated from each other. Each of the touch electrodes is electrically connected to a driving circuit via one touch lead. The touch electrodes and the touch leads are located in the same layer. A part of the touch electrodes are divided into multiple sub-electrodes by touch leads adjacent to the divided touch electrodes. The sub-electrodes of each of the touch electrodes are electrically connected to each other via at least one bridge which is located in a different layer from the touch electrode, to reduce parasitic capacitances between the touch leads and the touch electrodes and alleviate an influence from the parasitic capacitances on touch performance.
