Capacitive touch screen technology is a touch technology widely used in smart phones, tablets, kiosks and other interactive display devices. It works based on the user's body capacitance. When the finger touches or approaches the touch screen surface, it will change the electric field on the screen. This change is detected by the EPM7032AELC44-7 capacitive touch chip on the touch screen. The capacitive touch screen is usually composed of two layers of conductive materials (usually transparent ITO), with an insulating layer between them. These conductive layers form a capacitive network, and electrodes for measuring capacitance are placed at four corners of the screen. When the screen is not touched, the capacitive network is uniform; When
