Nippon Electric shows off glare-free 'invisible glass'

updated 07:05 pm EDT, Mon October 31, 2011

Films make glass 16x less reflective than normal

Nippon Electric Glass is showing off a new technology that can be used to create virtually almost non detectible "invisible glass". The company uses a process that creates an anti-reflective film on both sides of a screen or display. With it, the presence of the glass is almost impossible to discern.

With conventional glass, about 92 percent of incoming light passes through the substrate. Eight percent is reflected back. With the new process, 99.5 percent of the light passes through, while only 0.5 percent is bounced back.

To achieve the affect, Nippon uses about 30 nanometer-thick layers to form each of the films. The luminous reflectance of the glass, when coated with the film, is less than 0.1 percent. With such a low level of reflection, it's very difficult to realize that the treated glass is actually present.

Nippon Electric has not provided any information as to when or how it intends to commercialize the technology, although it will primarily be useful for notebooks, phones, and tablets, where glare is a frequent problem. [via Tech-On!]
