Abstract
A waterproof user interface panel includes an electronic display assembly having a touch sensitive surface for activation of touch switches, and a housing including a cutout area. A protective film is disposed over the assembly and secured to the housing. The housing includes a top surface, a bottom surface and a peripheral sidewall to define a housing cavity. Sealing material covers the bottom surface, with a void between the top surface of the sealing material and the electronic display assembly. A vent is provided between the void and the external environment to allow air to pass. A filter may be positioned in the vent to prevent the passage of water droplets through the filter while allowing the passage of air and water vapor.
