Scientists Find Secret to Smudge-Free Screens

by Caleb Johnson on August 22, 2009 at 12:21 PM


No matter how clean you keep your fingers, you'll be hard-pressed to keep the screen free of smudges and glares. However, scientists may have found a new way to combat, or possibly get rid of, the problem.

Scientists at the 238th National Meeting of the American Chemical Society released a report Thursday, according to Cellular News, detailing a new way of testing smudge- and reflection-resistant coatings. The findings could lead to major improvements for touchscreen devices -- from smart phones to MP3 players. Dr. Steven R. Carlo says that while smudge-, scratch- and reflection-resistant coatings have become standard on devices, these chemicals are not well understood by the scientific community.

Carlo and his team discovered that anti-reflective properties increase with more layers of coating, and that the elements silica and aluminum fight glare better than others. Sure, this study won't provide a quick fix, but it's nice to hear improvements are on the way. We dream of the day we can throw away those air bubble-prone screen protectors. [From: Cellular News]
