3M unveils large-format touchscreens

NEW YORK — 3M Touch Systems Inc. announced the expanded product offering of MicroTouch DST touchscreens for large-format interactive digital signage applications in 32, 40, 42 and 46-inch 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.

MicroTouch DST touchscreens are available as interactive NEC LCD displays or Pixelink all-in-one computer displays from Richardson Electronics Ltd.

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 touchscreens 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.
