1. A single-layer two-dimensional touch sensor comprising a substrate and a flexible printed circuit board, wherein a plurality of first electrodes and a plurality of second electrodes are disposed on the substrate, the first electrodes and the second electrodes form capacitor structures, the plurality of first electrodes is arranged in parallel and disposed along a first direction, a group of second electrodes is disposed between each two adjacent first electrodes without directly contacting with the first electrodes, the second electrodes in the group are arranged along a second direction which is perpendicular to the first direction; the first electrodes are spaced from the second electrodes, and a filler of electrically conductive material is disposed between the first electrodes and the second electrodes, each second electrode is provided with a toothed structure extending along the second direction, the toothed structure of one second electrode is meshed with the toothed structure of the adjacent second electrode, such that lead lines of all second electrodes are capable of being directly led out to the flexible printed circuit board, in each group of second electrodes, the lead lines of the second electrodes at intermediate positions are not adjacent the first electrodes, wherein a gap between adjacent two first electrodes is not greater than 10 mm. |
