CPC G06F 3/0446 (2019.05) [G06F 3/0412 (2013.01); G06F 3/041662 (2019.05)] | 20 Claims |
1. A touch panel, wherein the touch panel comprises:
at least one first touch area, wherein the at least one first touch area comprises a plurality of self-capacitance modules, the plurality of the self-capacitance modules are independent of each other;
at least one second touch area, wherein a mutual capacitance module is formed between the at least one second touch area and the at least one first touch area; and
a control module, wherein the plurality of self-capacitance modules of the at least one first touch area are electrically connected with the control module through first connecting wires respectively, and the at least one second touch area is electrically connected with the control module through second connecting wires; and
the control module is configured to determine a horizontal coordinate of a position at which a touch action occurs by means of a self-capacitance obtained by the at least one first touch area, and to determine a vertical coordinate of the position by a mutual capacitance between the at least one first touch area and the at least one second touch area, when the touch action occurs in the at least one second touch area;
wherein, a number of the second connecting wires is less than a number of the first connecting wires.
