HDTV News: LG Philips is planning to reveal a 52-inch (132cm) multi-touch LCD at the Consumer Electronics Show which opens in Las Vegas on 7 January. The model is the largest multi-touch LCD in the world.Multi-touch screens represent an advance on conventional touchpanels which use capacitive resistance to measure touch and only allow input from one point on the screen.
Multi-touch screens, on the other hand, use small infrared sensors, which allow input from more than one point.
Input can be either from fingers or other instruments, and multi-touch technology is also able to recognise gestures such as the movement of fingers.
The technology is expected to allow users to zoom in on images, such as maps, and manipulate images with two hands.
