A 30-inch large format presentation display has been developed by NEC-Mitsubishi.

The LCD3000 has been designed for installation in airports, railway stations and reception halls. It is equipped with digital and analogue connector options.

John McGrath, NEC-Mitsubishi's UK MD, explains that the display can also be used in the home in place of Plasma screen displays, though it is not being directly marketed at home consumers.

McGrath points out that LCDs such as the LCD3000, don't suffer from the "burn-in" issues that affect plasma displays. NEC-Mitsubishi's research reveals that if a logo is displayed on a Plasma screen, in just 30 minutes it will "burn-in" to the screen leaving a permanent mark.

However, David Hobbs, an Hitachi spokesperson, plays down the significance of burn in. He says: "It is something that can affect Plasma if a static image is left on for a very long period. And it would be the same with a conventional TV."

However, McGrath is convinced that LCDs' superiority over plasma screens is reflected in their cheaper total cost of ownership and (30 per cent) and lower power consumption: "We say LCDs will last twice as long as Plasma screens. At the very least, LCDs have a third greater life expectancy."

Hobbs casts doubt on McGrath's longevity claims. He says: "The average life of an LCD panel is 60,000 hours and 30,000 hours for a Plasma, but when you consider that 30,000 hours is eight hours a day, seven days a week, for over ten years, could a customer want or expect any more?"

The LCD3000 display is available now priced at £2,995.
