      We all know that the capacitive screen is actually a special conductive material attached to the glass surface. So when the finger touch the screen, the electric shock capacitor will change, so that the oscillator frequency connected with the change, by measuring the frequency changes can determine the touch location to obtain information.


      The screen part of the resistance touch screen is a multilayer composite film attached to the surface of the display. The glass or plexiglass is used as the base layer. The surface is coated with a transparent conductive layer, which is covered with an outer surface hardening, Of the plastic layer. When the finger presses on the touch screen, where the two layers of conductive layer contact, the resistance changes, in both X and Y direction of the signal, and then send touch screen controller.


      With the popular words to explain is: capacitive screen hand operation up better, because it is the body as an electrode for induction. Resistive screen is by pressing the resistance of the particle-year-old induction, suitable for hand gloves and can not touch the direct use of the occasion.


      According to market research firm DisplaySearch is expected, 2018 global touch screen revenue will rise to 31.9 billion US dollars. Among them, the capacitive touch screen with a multi-touch sensitive, high transmittance, long life and other excellent performance, market recognition continues to improve, has occupied the entire touch screen market share of the first. According to the terminal industry research room research, China's industrial capacitance screen market value in 2014, about 40 billion yuan of the share can be converted to 2020, is expected to have more than 600 billion industrial capacitance screen market value, the market capacity can be described as huge The
