Claim 17:
18. A touch panel, comprising a touch electrode structure, wherein the touch electrode structure comprises a first touch electrode and a second touch electrode, wherein the first touch electrode extends along a first direction, the second touch electrode extends along a second direction, the first direction intersects with the second direction;
the first touch electrode and the second touch electrode are insulated from and intersect with each other to form a mutual capacitance for touch detection;
the first touch electrode comprises a first hollow region, the second touch electrode comprises a second hollow region, and a hollow area of the first touch electrode is greater than a hollow area of the second touch electrode; and
the touch electrode structure further comprises at least one first dummy electrode, the at least one first dummy electrode is within the first hollow region and is arranged in a same layer as at least part of the first touch electrode, and the at least one first dummy electrode and the at least part of the first touch electrode are insulated from each other;
the first touch electrode comprises a plurality of first touch electrode portions connected in sequence in the first direction, and the second touch electrode comprises a plurality of second touch electrode portions connected in sequence in the second direction;
wherein each first dummy electrode comprises a plurality of first interdigital structures, and each first interdigital structure are embedded in the first touch electrode portion where the first interdigital structure is located in a same plane.
