A few days ago, Lenovo officially announced the launch of a 17.8 pound, 27 inch all-in-one Windows 8 tablet IdeaCentre Horizon Table PC. At the same time, Lenovo also said that 27 inch is not the end, and another 39 inch tablet code named "Gamma" is under development. However, if you see the 84 inch tablet displayed by 3M, you will instantly feel Lenovo is weak.

This super large tablet that destroys the three views was exhibited at CES by 3M. During CES last year, 3M once exhibited a 46 inch tablet computer. The product prototype on display is a tablet, but it can already support up to 40 points of multi touch (last year's 46 inch tablet can only support 20 points of touch), and this is a 4K concept tablet with a resolution of 3840x2160, which is a huge leap compared with last year's 1080P tablet.

Because the tablet is too large, you can't play with both hands, but it still has great prospects in public areas such as museums and schools. 3M predicts that the tablet is expected to be launched in the third quarter of this year, which will support up to 100 points of multi touch.

The tablet video is as follows:
