TFT-LCD notebook panel is dirt-resistant

Dirt-resistant LCD panel

LG.Philips LCD has developed a dirt-resistant 15.4-inch TFT-LCD panel for notebooks, which allows for easy removal of dust, smudges, fingerprints and even permanent ink.

TFT-LCD panels usually feature a coating on the surface of the polarizer film, designed to reduce glare and reflections. Because of their chemical properties, some of these coatings have a tendency to hold onto dirt and oil. A computer user's fingers are a ready source of both, and people touch the hinged screens on notebook computers quite often to adjust them.

Generally, to make LCD panels dirt-resistant, manufacturers must add a second coating to the polarizer film in addition to the glare-reduction coating. This is a time consuming process that slows delivery time and adds to the cost of panels. LG.Philips LCD claims it has found a way to eliminate this additional step while also delivering 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 Byung-Chul Ahn, head of development of advanced technology unit at LG.Philips LCD.

"Like millions of other people, we use notebooks when traveling on business. Fingerprints have always been an especially big annoyance, and if they are not cleaned off immediately they become even harder remove from the screen. That is why we developed this new technology," Ahn added.

The new technology will initially be used on LG.Philips LCD's 15.4in. widescreen panels for notebooks.

LG.Philips LCD said it would start mass production of the new panel in 1H 08. The company plans to expand availability of the new technology to notebook panels of all sizes by end of next year.
