Claim 19:
20. A driving method of a touch panel, wherein the touch panel comprises a first substrate and a second substrate, being opposite to the first substrate and overlapping with the first substrate; the first substrate comprises a first electrode pattern layer, the first electrode pattern layer comprises a plurality of first electrode blocks, and the plurality of first electrode blocks are insulated from each other and arranged in a first array with a plurality of rows and a plurality of columns; the second substrate comprises a second electrode pattern layer, a plurality of touch lead lines, and a third electrode pattern layer; the second electrode pattern layer comprises a plurality of second electrode blocks, wherein the plurality of second electrode blocks are insulated from each other and arranged in a second array with a plurality of rows and a plurality of columns; the plurality of second electrode blocks correspond to and are electrically connected with the plurality of first electrode blocks, respectively, and the plurality of second electrode blocks are respectively electrically connected with the plurality of touch lead lines to process an electrical signal of a touch operation; the third electrode pattern layer comprises a plurality of third electrode blocks, wherein the plurality of third electrode blocks are insulated from each other and arranged in a third array with a plurality of rows and a plurality of columns, and the plurality of second electrode blocks are insulated from the plurality of third electrode blocks to form a plurality of touch capacitors, respectively; and
the method comprises:
in a touch phase, providing a periodic touch driving signal to the plurality of second electrode blocks and receiving a touch detection signal from the plurality of second electrode blocks through the plurality of touch lead lines, respectively, and providing a second common voltage signal to the plurality of third electrode blocks or allowing the plurality of third electrode blocks to be in a floating state.
