Trivium brightens up LCD screens with new lens

The days of laptop users being forced indoors on sunny days because they can't read their screens in bright light are coming to an end, according to US-based Trivium Technologies. The company is developing a flexible, polymer thin film that will improve the quality of liquid crystal display (LCD) screens which the company claims is the first passive film technology of its kind.

The Trivium Diodic Lens, a film placed behind the LCD, allows 100 per cent of backlight to be transmitted and remains 85 per cent reflective, according to Timothy Wojciechowski, chief executive officer of Trivium. This allows for a clear, readable screen under bright outdoor lighting.

The film also optimises ambient light - which accounts for 90 per cent of available light - so less power consumption is needed in low light or night-time conditions. The lens will "increase battery life by 200 per cent," Wojciechowski said, adding that "the display uses 60 per cent of the battery."Currently, LCD screens are limited by the amount of reflected light, transmitted light or both that can simultaneously be used to create an image.

Besides saving power, the new technology will ease user eyestrain.

Costs to the consumer for the new technology will be minimal, amounting to less than 5 per cent of the cost of an LCD screen, and projected sales of the film are expected to exceed $US300 million, the company said.

Trivium expects the lens to be used across LCD markets, including handheld devices such as PDA, mobile phones and car navigation systems. Commercial production is expected to begin by October of next year, according to Wojciechowski, and the company is currently negotiating with laptop and handheld device manufacturers to license the technology. Trivium plans to maintain marketing and sales rights to all products and technology, Wojciechowski said.

The technology for the Trivium Diodic Lens was developed Neil Lubart, a former IBM scientist.
