Capacitive Touch Screens

Stadium IGT designs and manufactures flexible capacitive touchscreens.

Case study: Vix Acis Research and Development Vandal Proof Bus Stop Information System

Pictured below is a Capacitive Touchscreen information centre located on a bus stop, which Stadium IGT manufacture for Vix Acis Research and Development. It has been designed with the British weather and the potential of vandalism in-mind.

The flexible capacitive touchscreen is mounted to the rear of the any transparent non-conductive material, which can be up to 10mm thick (Glass, Polycarbonate, Acrylic). The Capacitive Touchscreen units are extremely reliable and can be fully sealed, enabling them to be installed in environmentally demanding areas such as onboard ships, in dirty or dusty environments, in public buildings or in the open.
