By 2016 there will be 19 billion* Internet connected devices on the planet; at least half of those are likely to be controlled by a high resolution Touchscreen interface.
Whether it's a smartphone, camera, tablet computer, public information kiosk, or a home entertainment centre, two things are for sure:
01 Unwanted reflection at the touchscreen surfaces significantly reduces the performance of the device and the enjoyment of the user.
02 Fingerprints and other surface contamination greatly impair the quality of the image and utility of the device. This is bad enough on a 3" smartphone but for a 50" home entertainment panel or a 20" public information kiosk, continually cleaning such a large surface would probably be a showstopper.
Mobile device power consumption is a major consideration. Unwanted reflection at both the inner and outer surface of touchscreen cover glass increases the power consumption of the device. Energy is lost at the inner surface, because the light from the led display is bounced back into the device, rather than transmitted to the user, energy is also lost at the outer cover surface, because the only way to counter a highly reflective screen is to turn up the brightness thereby driving up the power consumption.
Optitune have created a coating for glass and transparent substrates that combines the qualities of anti-reflection and anti-finger contamination (finger smudge) in a single layer coating, and it also provides a hard scratch resistant protective layer for the sensitive touch panel cover glass.
