Capacitance touch screen technology description:
Capacitive touch screen is a four-storey glass screen surface and
laminated within the glass screen is coated with a layer of ITO,
the outermost layer is a thin layer of silica glass, laminated ITO
coating as a face, four electrode leads in the four corners, inner
ITO good shielding to ensure a good working environment.
When finger touch the metal layer that is, because the body farm,
users and touch-screen surface with a coupling capacitor, high
frequency current, capacitance is a direct conductor, so fingers
sucked away a very small amount of current from the contact point.
The respectively current outflow from the touch electrode on the
four corners of the screen, and flows through the four electrode
current is proportional to the distance from the fingers to the
four corners, controller through the accurate calculation of the
four current percentage, came to the location of the touch point.
