3M unveiled an 84-inch multitouch table with 40-point input

LAS VEGAS 3M Touch Systems, a wholly-owned subsidiary of 3M Company, as an innovation leader in projected capacitive (PCAP) touchscreen technology and electronics, , is showcasing its multi-touch expertise at the Consumer Electronics Show (CES) 2013 by featuring an 84-inch multi-touch display prototype. This combination of expansive on-screen collaboration space and 3M’s high-performance multi-touch technology offers users an unparalleled multi-user experience as a multi-touch display wall or interactive table.


“3M continues to challenge the size limitations of high-performance multi-touch technology, and the investments we have made in developing robust and proprietary PX electronics platform are enabling us to achieve our innovation goals,” says Diego Romeu, business operations manager, 3M Touch Systems. “Our 84-inch multi-touch prototype display demonstrates 3M’s ability to scale PCAP electronics and sensor manufacturing to meet the need of our customers for increasingly larger format touch solutions.”

The table is still in prototype mode, but already supports up to 40 simultaneous touches, and features a display with 3840 x 2160 pixel resolution.


The table’s projective capacitive display runs on wired-based sensors, unlike the ITO-based sensors used in last year’s version, which the company says allowed them to scale up without sacrificing performance. The idea is to use the table in educational settings, including museums and schools, though 3M has yet to announce a specific price. By the time the table hits the market in Q3 of this year, it should support more than 100 concurrent touches.
