3M DST

Traditional touch technologies detect touch locations by interrupting acoustic waves, optical fields or infrared light above the surface of the touch screen. Dispersive Signal Technology (DST), however, precisely calculates touch locations within the glass substrate by analyzing the bending waves created by the user's touch. This allows for fast, accurate and reliable touch performance that is unaffected by contaminants, scratches or static objects on the screen, as well as enabling stylus support and multi-user capability. This fully integrated touch solution is perfect for interactive digital signage and point-of-information applications. 3M Dispersive Signal Technology (DST) is poised to become the touch technology standard for large-format interactive displays.
