Water Handling

Since water is conductive, false touch signals may be generated when water comes into contact with the PCAP touch panel. Thus, for mission critical systems or equipment, the ability to prevent false touch events caused by water is an important part of PCAP touch specifications.

Currently our PCAP products are able to avoid the occurrence of false touch signals when there is a small amount or flowing water on the surface of the touch panel. If water is present, dry areas of the touch panel surface will still function properly. Also, touch functionality will be turned off automatically when a large amount of water is detected. Once water on the surface is wiped dry, the touch panel will resume normal touch functionality.
