LG.Philips to release dirt-resistant TFT-LCD screen


South Korea's LG.Philips LCD said yesterday that it has developed a dirt-resistant screen for notebook computers by using a principle similar to non-stick frying pans.

The company said that the thin-film-transistor liquid-crystal-display (TFT-LCD) panel allows easy removal of dust, smudges, fingerprints and even permanent ink.

It said in a statement it would start mass production in the first half of next year.

It said that as some anti-glare coatings also retain dirt and oil from users' fingerprints, manufacturers must add a second coating at added cost to make the panels dirt-resistant.

LG.Philips LCD said that its new panel would eliminate this additional step and also deliver superior dirt resistance.

"Our new panel employs a principle similar to that used on non-stick frying pans. Dirt and oil can easily be wiped away," said Ahn Byung-chul, development chief for advanced technology.

"Like millions of other people, we use notebook computers when traveling on business. Fingerprints have always been an especially big annoyance, and if they are not cleaned off immediately they become even harder to remove from the screen," Ahn said.

"That is why we developed this new technology," he said.

LG.Philips LCD is a joint venture between South Korea's LG Electronics and Philips Electronics of the Netherlands.
