Corning is the company behind the wildly successful Gorilla Glass, it’s the layer of glass that you’ll find on the top of most high end smartphones and tablets. It has a much greater resistance to scratches and cracks than normal soda lime glass which makes it ideal for the application. The problem with Gorilla Glass as with all other glass on smartphones and tablets is that they have a problem with direct sunlight causing glare on the screen. Smartphones typically deal with the problem by cranking up the display brightness so that it can cut through the brightness of the ambient light outside. Glare is such an issue that Nokia uses polarising filters on its top end Lumia smartphones which it calls ClearBlack technology which helps fight glare while others like Apple have bonded the gorilla glass to the LCD and digitiser to cut down on glare.
Smartphones and tablets are already using generation 3 of Gorilla Glass to help stave off cracks and scratches but the New York based company isn’t resting on its laurels. Corning’s senior vice president and operations chief of staff, Dr. Jeffrey Evenson presented the results of Corning’s latest work on reducing glare. The picture above shows a piece of glass that appears to have a hole in the middle of it, the hole is in fact a portion of the glass sheet coated by Corning’s new anti-reflection solution.
If you can eliminate glare from a device then the screen brightness can remain more constant which will improve battery life in general which every smartphone user could do with.
