The other type is a capacitive screen with a G + F + F structure, the structure is that a glass cover plate is attached to an ITO Film functional sheet, the ITO Film functional sheet is formed by attaching two PET films which are respectively an induction layer PET Film and a driving layer PET Film, the induction layer is arranged on the upper side, and the driving layer is arranged on the lower side. The action principles of the capacitive screens of the two structures are consistent, and the structures of the base materials are different. When a finger touches the surface of the glass cover plate, due to an electric field of a human body, the finger and the surface of the touch screen form a coupling capacitor, and for high-frequency current, the capacitor is a direct conductor, so that the finger sucks a small current from a 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.
