[0002] TP touch functional sheet sensor is an important component of capacitive touch screen (TP), mainly plays the role of inductive touch operation and converts it into electric signal, capacitive inductive principle: use human body electric field, when the finger touches the screen, the coupling capacitor between the finger and the conductive layer (usually ITO, namely indium tin oxide) on the screen is formed. Due to the approach of the finger, the capacitance value of the conductive layer at a particular position will change. Signal detection and processing: the electrode array on the screen will detect this capacitance change, by measuring the change amount of capacitance, the controller can accurately calculate the position coordinates of the touch point. Then, these position information will be transmitted to the processor of the electronic device to realize the corresponding operation, such as clicking, sliding, zooming, etc., the structure is ITO conductive layer: this is the core part, ITO is a kind of transparent conductive material, plated on glass or other substrates, forms the electrode array of conductive. The electrode array is usually divided into horizontal and vertical two directions, and the capacitance change at the intersection point can determine the position of the touch point. Glass substrate: as support and carrier, provides stable attachment basis for ITO conductive layer. Glass substrate has good transparency and mechanical strength, can guarantee the normal work and service life of touch screen. Protective film: covers ITO conductive layer and glass substrate, plays the role of protection, prevents the conductive layer from being scratched, corroded or affected by other external factors. Protective film usually has good wear resistance and scratch resistance. Metal lead: used for connecting ITO conductive layer and external circuit, transmits the detected capacitance change signal to the controller for processing. Metal lead needs to have good conductivity and reliability to ensure accurate signal transmission.
