Abstract: There is provided a single-layer capacitive touch sensor including a plurality of sensing units arranged in a matrix on a substrate. Each of the sensing units has a Out electrode, a second electrode and a third electrode. The second electrode is arranged in a ring shape and electrically isolated from the first electrode, and the first electrode is located in an interior space of the ring shape. The third electrode is arranged outside of the interior space and electrically connected to the first electrode, wherein the second electrode of at least a part of the sensing units is configured to respectively form a mutual capacitance with the third electrode of two adjacent sensing units.

Abstract: The present disclosure provides a capacitive touch panel, a sensing method thereof, a touch device using the same, and an input apparatus. The capacitive touch panel includes a substrate, a plurality of first scan lines, and a plurality of second scan lines. The first scan lines and the second scan lines are respectively formed on the substrate wherein the first scan lines and the second scan lines are interlaced with each other. The first scan lines and the second scan lines are capacitively coupled to each other forming a plurality of sensing regions. Moreover, any one of the second scan lines can formed a sensing region with one or more first scan lines.
