Touchscreen overlays add touch input to a display that was not originally built with it: infrared or capacitive overlay frames that mount around a monitor or commercial display and turn its surface into a touch interface, without replacing the display itself. Where an existing screen just needs touch capability added, an overlay is the upgrade path that avoids buying a new display.
Overlays are sized and mounted to a specific display's dimensions and bezel - order by the exact model, since a mismatched overlay leaves touch-detection gaps at the edges or does not mount securely. Confirm the overlay's touch technology is supported by the software or operating system driving the display, since infrared and capacitive overlays register touch differently. For public-facing kiosks or signage, an overlay's durability rating matters as much as its touch accuracy. COLAMCO supplies touchscreen overlays for the interactive display and kiosk programs business, government, and education organizations deploy.
