Abstract
A waterproof touch screen user interface panel constructed in such a way that readily available LCD displays and touch screen switches can be used in a wet environment. A thin plastic film is placed over the top of a touch screen/LCD assembly using moisture resistant adhesive to protect the assembly from the panel's top side and a specially constructed housing allows the use of silicon gel to protect the panel from the bottom side. The plastic film, typically a polycarbonate film, is thin enough to allow activation of the touch screen switches with a soft touch, yet rigid enough to prevent false activations of the switches until touched.
