LG to launch 52in multitouch screen at CES

Huge LCD uses similar touch tech to iPhone

LG.Philips LCD is planning to unveil a 52in multi-touch LCD at next week's Consumer Electronics Show (CES). The screen is 5in larger than one it recently showed in Japan and is the largest display of its type in the world, the company said.

Multi-touch screens differ from conventional touchpanels because they allow input from more than one spot on the screen so, for example, an image can be manipulated from opposite corners. The most famous current example of the technology is the display on Apple's iPhone and iPod Touch devices.

With the technology helping to make the iPhone a smash hit display makers are now pursuing its inclusion in screens. The LG.Philips 52in screen uses an infrared image sensor to gauge input from fingers or other instruments and can recognise gestures such as the movement of fingers. It boasts full HD resolution (1,920 pixels by 1,080 pixels).

Additionally, the company will be showing an 84in multi-touch display that is made up of four 42in panels joined together.

LG.Philips LCD will also unveil a 47in 'triple-view' screen. This has a filter over the front that sends light from pixels in one of three different directions so that three images can be displayed at once: one to viewers on the right of the screen, one to people in front of it and one to those on the left. The feature is being positioned at public display applications for use in advertising.

Also at CES the company will show a 47in double-sided screen that is made up of a single backlight sandwiched between two LCD panels and a 42in transreflective panel for outdoor advertising use.

International CES opens in Las Vegas on Jan. 7.
