Abstract

A touch device has multiple charging traces distributed under the touch operation area. When the object hovers over or contacts the touch operation area, the control unit of the touch device obtains the corresponding position of the object through the sensing signal of the electrode units. The control unit in turn connect the charging traces adjacent to the corresponding position of the object to form at least one charging loop. In the process of the touch operation on the touch device, the object can be charged at the same time, and the convenience of use can be improved.
