Abstract:
1. A touch panel, comprising: a transparent substrate having a surface, wherein the surface is parallel to a plane formed by a first direction and a second direction; a plurality of first touch sensor pads arranged in a matrix on the surface of the transparent substrate, wherein the first touch sensor pads along the first direction are connected in series, and each first touch sensor pad includes a first hollowed-out pattern and the first hollowed-out pattern comprises a plurality of regularly arrayed through holes; a plurality of second touch sensor pads arranged in a matrix on the surface and staggered between the plurality of first touch sensor pads; a dielectric layer disposed on the plurality of first and second touch sensor pads; a plurality of third touch sensor pads arranged in a matrix on the dielectric layer, wherein each third touch sensor pad includes a second hollowed-out pattern and a solid portion defining the second hollowed-out pattern and the second hollowed-out pattern comprises a plurality of through holes, and a portion of the solid portion of each third touch sensor pad overlaps a portion of the first hollowed-out pattern of the respective first touch sensor, each through hole in the third touch sensor pad overlaps a portion of a regularly arrayed through hole in the first hollowed-out pattern; and a plurality of fourth touch sensor pads arranged in a matrix on the dielectric layer and staggered between the plurality of third touch sensor pads, wherein the fourth touch sensor pads along the second direction are connected in series.
