Philips to Unveil 52-inch Multi-Touch LCD at CES

LG.Philips LCD is planning to unveil a 52-inch multi-touch LCD (liquid crystal display) at next week's Consumer Electronics Show, it said Monday. The screen is 5-inches 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. Probably the most famous current example of the technology is the display on Apple's hit 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 52-inch screen uses an infrared image sensor to gauge input from fingers or other instruments and can recognize 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 84-inch multi-touch display that is made up of four 42-inch panels joined together.

LG.Philips LCD will also unveil a 47-inch "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 47-inch double-sided screen that is made up of a single backlight sandwiched between two LCD panels and a 42-inch transreflective panel for outdoor advertising use.

International CES opens in Las Vegas on Jan. 7.
