Front Screen Glass lens for iphoneXS with OCA

                                                                                   What's Surface acoustic wave touch screen

Surface acoustic wave, a type of ultrasonic wave, is a mechanical energy wave that propagates shallowly on the surface of a medium (such as rigid materials such as glass or metal). Through the wedge-shaped triangular base (strictly designed according to the wavelength of the surface wave), directional and small-angle surface acoustic wave energy emission can be achieved. The performance of surface acoustic wave is stable, easy to analyze, and has very sharp frequency characteristics in the process of shear wave transmission. Conductive materials, detection technology and other technologies are quite mature.

     The touch screen part of a surface acoustic wave touch screen can be a flat, spherical or cylindrical glass plate installed in front of a CRT, LED, LCD or plasma display screen. The upper left corner and the lower right corner of the glass screen are respectively fixed with vertical and horizontal ultrasonic transmitting transducers, and the upper right corner is fixed with two corresponding ultrasonic receiving transducers. The four perimeters of the glass screen are engraved with reflective stripes at a 45° angle from sparse to dense.
