aha interactive touch screen.Surface acoustic wave surface acoustic wave is a mechanical wave that propagates along the surface of the medium. The touch screen is composed of a touch screen, a sound wave generator, a reflector, and a sound wave receiver. The sound wave generator can send a high-frequency sound wave across the screen surface. When a finger touches the screen, the sound waves on the touch point are blocked to determine the coordinate position. The surface acoustic wave touch screen is not affected by environmental factors such as temperature and humidity, has high resolution, excellent scratch resistance, long life (50 million times without failure), high light transmittance (92%), and can keep clear Image quality, no drift, just need to correct once when installing. There is a response of the third axis (that is, the pressure axis), which is most suitable for public places. The touch screen part of the surface acoustic wave touch screen can be a flat, spherical or cylindrical glass flat plate, which is installed in front of the CRT, LED, UCD or plasma display screen. This glass plate is just a pure tempered glass, which is different from other touch screen technologies without any film and cover. The upper left and lower right corners of the glass screen are fixed with vertical and horizontal ultrasonic cross-transmission transducers, respectively. The upper right corner is fixed with two corresponding ultrasonic receiver transducers. The four perimeters of the glass screen are engraved with 45-degree angles Very fine reflection stripes from sparse to densely spaced.
