3M unveils 84″ multitouch tabletop with UHD display and a 100-point input

3M is showing off its 84-inch multi-touch table at CES this year . Like Microsoft’s original “Surface” tabletop touchscreen, the gigantic capacitive table is the successor to last year’s 46-inch model; however, the device is still under development until its expected launch during the second half of this year.

This Tabletop differs from last year’s model in a couple of ways.

There is a  substantial bump in resolution from 1080p (1920 x 1080)  to UHD (3840 x 2160). Additionally, the screen can handle more simultaneous inputs — 40 at a time. That’s double the amount of concurrent touch inputs the old model could handle. The Verge says 3M expects that number to increase to 100 though, before it makes it into production later this year.

3M has also switched from ITO-based sensors to a “wire-based” solution, which the company says allowed them to achieve such a large size without “degrading touch performance“.
