Daily use of three anti-Tablet PC touch screen is divided into several types, many people on the resistive and capacitive touch screen may be more familiar with what, then what is the surface acoustic wave touch screen? What are the characteristics of it?
Surface acoustic wave touch screen from temperature, humidity and other environmental factors, high resolution, excellent scratch resistance, long life (50 million times without failure), high transmittance (92%), to maintain a clear and transparent Image; no drift, only one time to correct the installation; a third axis (ie pressure axis) response, the most suitable for public places.
Surface acoustic wave is a kind of ultrasonic wave, which is the mechanical energy wave propagating on the shallow surface of the medium. Through the wedge-shaped triangular base (according to the surface wave wavelength strictly designed), can be targeted, small angle surface acoustic energy emission. Surface acoustic wave performance is stable, easy to analyze, and in the process of cross-wave transmission has a very sharp frequency characteristics, in recent years in nondestructive testing, angiography and echoes and other applications in the development of fast.
But the surface acoustic wave touch screen also has some limitations, it is easy to be the impact of water droplets and dust, and further improve the method is to increase the dust or dirt to strengthen the monitoring, Shenzhen Erelion Group with the network of three anti-Tablet PC Surface acoustic wave touch screen is the above characteristics of these.
