Touch electrode structure, touch pad, and method for fabricating the touch electrode structure

A touch electrode structure, comprising first touch electrodes and second touch electrodes alternately arranged at a same layer, wherein the touch electrode structure further comprises:

• first connecting sections electrically connecting adjacent first touch electrodes arranged in a first direction;
• and
• second connecting sections electrically connecting adjacent second touch electrodes arranged in a second direction, wherein the first connecting sections and the second connecting sections overlap with each other in overlapping areas;
• there are such a first insulating medium between the first touch electrodes and the second touch electrodes that insulates the first touch electrodes and the second touch electrodes from each other;
• there are such a second insulating medium between the first connecting sections and the second connecting sections in the overlapping areas that insulates the first connecting sections and the second connecting sections from each other;
• and
• each of a thickness of the second insulating medium, a thickness of the first connecting sections in the overlapping areas and a thickness of the second connecting sections in the overlapping areas is not only less than a thickness of the first touch electrodes, but also less than a thickness of the second touch electrodes;
• wherein the first touch electrodes are provided with first grooves that correspond to the overlapping areas, wherein the second insulating medium sections in the overlapping areas are located in the first grooves;
• an upper surface outside the first grooves of the first touch electrodes is flush with an upper surface of the second insulating medium sections.
