Touch panel

A touch panel comprising:

• a sensing module configured for sensing changes of capacitive signal values or electromagnetic signal values, wherein the sensing module consists of a first conductive layer and a second conductive layer;
• the first conductive layer is insulated and spaced from the second conductive layer;
• the first conductive layer comprises a plurality of first electrodes, the plurality of first electrodes substantially extend along a first direction and are spaced from each other;
• and the second conductive layer comprises a plurality of second electrodes, the plurality of second electrodes substantially extend along a second direction and are spaced from each other;
• a control module configured for driving and detecting the sensing module, wherein the control module comprises a switching circuit;
• the sensing module is capable of being switched between an electromagnetic sensing module and a capacitive sensing module via the switching circuit;
• and the switching circuit is capable of connecting each two of the plurality of first electrodes to form a plurality of closed transverse sensing coils and connecting each two of the plurality of second electrodes to form a plurality of closed vertical sensing coil;
• and
• a charging wiring module comprising at least one closed coil, wherein the charging wiring module is arranged around the sensing module.
