Customized multi touch capacitive foil

Product Introdution

Capacitive touchscreen is the use of the body's current sensing work. The capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are coated with ITO. The outer layer is a thin layer of silica-glass protective layer. The interlayer ITO coating is used as the working face. Four electrodes are drawn from the four corners and the inner ITO is used as the shielding layer to ensure a good working environment. When the finger touches the metal layer, due to the human body's electric field, the user and the touch screen surface form a coupling capacitor, which is a direct conductor for high-frequency current, so the finger sucks a small current from the contact point. The current flows from the four electrodes on the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners.
