Large-Format Touch Screens from 3M Target Interactive Digital Signage Applications

MicroTouch DST Touch Screens

NEW YORK -- 3M Touch Systems, Inc. today announces the expanded product offering of MicroTouch DST touch screens for large-format interactive digital signage (IDS) applications in popular 32", 40", 42" and 46" screen sizes. Based on 3M's patented Dispersive Signal Technology (DST), MicroTouch DST touch screens offer an ideal solution for large-format interactive applications that require fast, accurate, reliable touch response. Other unique features include operation unaffected by surface contaminants and "dynamic touch", which ignores static objects on the screen and allows for multi-user touch capabilities.

"DST touch screens offer digital signage providers the reliable and versatile touch solution their public applications require," says David Henry, Marketing Manager, 3M Touch Systems. "DST touch screens offer unique qualities not found in most existing large-format touch solutions and should raise operating expectations for this category of touch screen."

MicroTouch DST touch screens are available as interactive NEC LCD displays or Pixelink all-in-one computer displays from Richardson Electronics, Ltd. "Our customers expect Richardson Electronics to provide the best touch solution available for their applications and we're confident that the MicroTouch DST touch screen satisfies that requirement," says John Bowab, Vice President, Custom Displays of Richardson Electronics Display Systems Group.

Dispersive Signal Technology recognizes touch by interpreting bending waves within the glass substrate created by the contact of a finger or stylus on the glass. Since bending waves are unaffected by on-screen contaminants and moderate surface damage, DST touch screens work reliably for most public environments and applications, such as interactive digital signage, public way finders, point-of-information stations, corporate directories, retail product selectors, as well as conference room and education presentation systems.
