    Technical Q & A

    Q: What is the principle of capacitive touch screen to achieve multi-touch?
    A: When the finger touches the capacitive screen, it affects the coupling between the two electrodes near the touch point, thus changing the capacitance between the two electrodes. When detecting the mutual capacitance, the lateral electrodes sequentially emit excitation pulse signals, and all the longitudinal electrodes receive signals at the same time, so that the capacitance values of all the intersections of the lateral and longitudinal electrodes can be obtained, that is, the capacitance of the two-dimensional plane of the entire touch screen. According to the two-dimensional capacitance change data of the touch screen, the coordinates of each touch point can be calculated. That is, the real multi-point coordinates can be calculated to realize multi-touch;

    Q: Is it possible to make an antibacterial capacitive touch screen? What is the main principle?

    A: Our company is able to manufacture anti-bacterial touch screen, what we do is to do special treatment on the surface of the capacitive touch screen to inhibit bacteria, our nano-silver anti-bacterial coating prevents bacteria grow by destroying its cell wall. it's a long-term germ terminator which safely kill over 99.99% common disease-making bacteria, fungi, and molds with no negative side-effect.
