1. An input device with an integrated UV disinfection system comprising:
a UV source;
a control system for operating the UV source;
a touch surface configured to receive user input, the touch surface including a UV transmissive overlay, the UV transmissive overlay having an external surface arranged to directly receive touches, the UV transmissive overlay having a UV transmission percentage of at least 65 percent; and
a reflective substrate disposed inwardly of at least a portion of the UV transmissive overlay, the reflective substrate having an initial reflectivity of at least 30% of UV radiation at a wavelength of 254 nm, wherein the reflective substrate is a UV reflective film extending adjacent the UV transmissive overlay, the UV reflective film being generally transparent to visible light;
wherein the UV source is positioned adjacent to the UV transmissive overlay such that operation of the UV source emits UV energy into the UV transmissive overlay, the UV energy passes through the UV transmissive overlay and disinfecting the external surface of the UV transmissive overlay.
