21.5 inch Capacitive Multi Touch Screen with USB port for Touch
Capacitive touch panel:
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
