Capacitive Touch Panel Technology
Capacitive touch panel 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.
How does a Capacitive Touchscreen Work?
Capacitive touch screens are built with a thin layer of conductive material, such as copper or Indium Tin Oxide (ITO), printed onto the underside of the display's insulating outer layer. When a finger touches the screen, a small electrical charge is drawn to the point of contact, which effectively becomes a functioning capacitor. The resulting change in the electrostatic field is then measured to pinpoint where the contact took place.
Projected Capacitive touchscreens are used on the vast majority of smartphones and tablets. PCap screens consist of a layer of glass, a matrix of electrodes and a protective film. The matrix of electrodes creates a three dimensional electrostatic field that registers even the slightest change in electrical current. So, when a conductive object, such as your finger or a stylus, comes into contact with the matrix of electrodes, the electric field is changed slightly, and the screen registers your touch.

Capacitance Touchscreen Construction
Several techniques are available to construct a capacitance touchscreen. These include conductive wire construction or the application of transparent conductive materials, such as Indium Tin Oxide (ITO), to a polyester (PET) film layer "sandwich" or to a glass substrate.
