Capacitive touch screen uses the body's current induction to work. The capacitive touch screen is a four-layer composite glass screen. The inner surface of the glass screen and the interlayer are coated with a layer of ITO, and the outermost layer is a thin silica glass protective layer. The interlayer ITO coating serves as the working surface, and four electrodes are drawn from the four corners, while the inner ITO is the shielding layer to ensure a good working environment. When the finger touches the metal layer, a coupling capacitor is formed between the user and the touch screen surface due to the human electric field. For high frequency current, the capacitor is a direct conductor, so the finger draws a small current from the contact point. The current flows from the electrodes at the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance between the finger and the four corners. The controller obtains the position of the touch point through the accurate calculation of the ratio of the four currents.
