Fundamentally Different Touch for Interactive Signage
For most popular large-format touch technologies, “touch position” is calculated when a finger interrupts an optical field, infrared light beams or acoustic waves on or above the surface of the touch screen substrate. Relying on these “active” surface properties makes these technologies susceptible to different types of interference or environmental limitations, which makes 3M’s Dispersive Signal Technology (DST) a fundamentally different touch solution for large-format display applications.
The MicroTouch™ DST Touch System, based on 3M Dispersive Signal Technology, consists of a chemically-strenghtened glass substrate with piezos mounted on each corner, mated to a sophisticated DST controller. The DST Touch System determines the touch position by pinpointing the source of “bending waves” created by finger or stylus contact within the glass substrate. This process of interpreting bending waves within the glass substrate helps eliminate traditional performance issues related to on-screen contaminants and surface damage, and provides fast and accurate touch attributes.
