Computing giant Microsoft has completed the take-over of Perceptive Pixel, a firm that specialises in making large multi-touch wall-mountable screens.
Used for presentations, the screens, which can be up to 82in (202cm), can be controlled by both touch and stylus.
Microsoft says it hopes to use the technology to enhance its Windows 8 operating system.
One analyst said the move could lead to an upgrade of Microsoft’s Kinect motion sensor.
US broadcaster CNN used the Perceptive Pixel (PPI) jumbo touch-sensing TV screen in 2008 to zoom in and out of a map during that year’s election coverage.
The displays sell for up to $80,000 (£50,996).
