Customized 21.5 Inch Projected Capacitive Touch Panel
Introduction of the Capacitive touch panel principle
Capacitive Touch Panel is to use the working current of induction of human body. The operational principle of the projected capacitive touch panel: There are two layers of the ITO layer under the surface of glass. This ITO layer respectively forms the electric field of X axis and Y axis, which can keep balance by crossing the surface of the class. Once the fingers approach the glass surface, the fingers and the electrode X axis or Y axis will form a new electric field, which can make the local capacitance change. Then the controller will determine the location based on capacitance changes.
