The current coatings for the iPhone, iPad and iPod Touch are not effective and lasts for a month but this new patent filed by Apple is apparently more effective in protecting the touch screen devices from smears.
The Physical Vapor Desposition technology will reportedly protect your iPhone, iPad, iPod Touch from fingerprints and avoid the need to constantly wipe out your device. This new technology coats the screens of your touch device with an oil resistant ‘oleophobic’ coating.
This technique applies thin films of vaporized materials onto i-device’s surface. This special coating comes in liquid form inside a pressurized bottle and is purged by an inert gas to avoid its contact with air, heat or humidity during the manufacturing process, before it is applies to the device’s surface.
