7 inch capacitive touch aluminum foil
Capacitive touch screen technology uses the current sensing of the human body to 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 a layer of ITO. The outermost layer is a thin layer of bauxite glass protective layer. The interlayer ITO coating is used as the working surface, and the four corners are taken out. Four electrodes, the inner layer of ITO is a shielding layer to ensure a good working environment. When the finger touches the metal layer, the user and the surface of the touch screen form a coupling capacitor due to the electric field of the human body. For high-frequency current, the capacitor is a direct conductor, and the finger sucks a small current from the contact point. The currents flowing from the electrodes on the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance from the corners of the finger, the controller accurately calculated by these four current ratio, obtained position of the touch.
