          The Working Principle of Surface Acoustic Wave (SAW) Technology

          A SAW touchscreen consists of a glass panel, transducers, reflection strips and cables. The transducers, cables and the reflection stripes are located on the front surface. The SAW controller sends electrical signals to transmitting transducers of both the X and Y axes. The transducers convert these electrical signals from the controller into ultrasonic waves which are then reflected by the reflector arrays and sent across the front, rear and side surfaces. These waves are then reflected back to the receiving transducers by another set of reflector array on each opposite side of the surface. The receiving transducers will convert the waves into electrical signals and feed them back to the controller.
          When the screen is touched, the finger absorbs a portion of the wave passing across the surface of the panel. The resulted change in ultrasonic wave frequency will be detected and a coordinate is calculated. This process happens independently for both the X and Y axes.
