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.

The Infrared Touch Screen is a touch frame which is usually installed in front of the display screen.The infrared touch technology depends on the interruption of an infrared light grid.The frame is integrated with a printed circuit board which contains a row of infrared LEDs and photo transistors hidden behind the bezel of the touch frame.Each of the infrared LED has a corresponding photo transistor set on the opposite end, creating a grid of invisible infrared light beams.
The bezel shields the electronics from the operating environment while allowing the IR beams to pass through.The Infrared Touch Screen controller sends light pulses sequentially through the LEDs.When a user touches the screen with his finger or other styli, the infrared light beams will be interrupted.The photo transistors from X and Y axes simultaneously detect the absence of the infrared light and register the X and Y axes coordinates.
