3M has brought large touchscreen displays to CES before-- but those products look positively Lilliputian compared to the mammoth 84-inch model on display Sunday night.
The screen uses projective capacitive multi-touch technology -- just like what's found in smartphones and tablets, but on a much, much grander scale. Resolution has been increased alongside physical dimensions; with a 3840 x 2160-pixel resolution, the device qualifies as a 4K display.
David Henry, marketing manager for 3M's touch group, said the giant touchscreen, which increases on the company's existing 46-inch model by more than 80%, is a prototype that will be shipping by the end of the year. The demonstration was running an app slated to appear as an exhibit at the Museum of Science and Industry in Chicago, one of many potential applications, he said. The retail space, for example, might harness the device to improve in-store experiences. Casinos have shown interest in the screen for table games. Henry said the plus-size touchscreen might even have a place in the enterprise, as many business intelligence units require methods for visualizing dense sets of data, such as layering demographics information, population density and sales figures over a map of all a store's locations.
