Background
The capacitive touch screen technology works by using current induction of a human body. The capacitive touch screen is a four-layer composite glass screen, the inner surface and the interlayer of the glass screen are respectively coated with one layer of ITO, the outermost layer is a thin-layer silica glass protective layer, the interlayer ITO coating serves as a working surface, four electrodes are led out from four corners, and the inner layer of ITO serves as a shielding layer to guarantee a good working environment. When a finger touches the metal layer, a coupling capacitance is formed between the user and the touch screen surface due to the electric field of the human body, and for high frequency currents, the capacitance is a direct conductor, so that the finger draws a small current from the contact point. The currents respectively flow out of the electrodes on the four corners of the touch screen, the currents flowing through the four electrodes are in direct proportion to the distances from the fingers to the four corners, and the controller obtains the position of a touch point through accurate calculation of the proportion of the four currents.
The control circuit and the control IC of the traditional capacitive touch screen are arranged in the screen body, and the touch screen needs to independently design and produce a mold aiming at each type of screen, so that the universality is not strong, the production period is longer, and the main defect of the traditional technology is overcome.
