During the MIT Mobile Technology Summit, Dr. Jeffrey Evenson, senior vice president and operations chief of staff for Corning, talked about the anti-reflection and the anti-microbial abilities of the next-generation Gorilla Glass. He also insisted that glass is an ideal enclosure for advanced display technologies such as OLEDs.
Why? Because OLEDs decay rapidly if exposed to water or oxygen, and it takes 30 billion years for a molecule of oxygen to pass through a piece of 1-millimeter-thick sheet of glass. That same trip would take a mere two weeks through the same thickness of plastic, he said.
That scenario leads to Corning's anti-reflection technology. Evenson showed a slide of a hand holding a sheet of normal glass used to cover a tablet. In the center of the sheet was a large hole about the size of an orange, only it wasn't an actual hole; it was a portion treated with Corning's anti-reflection tech. Unlike the rest of the sheet, this portion didn't reflect large amounts of the blue sky and flowing clouds in the sky above.
According to Corning, device screen visibility in the sunlight is heavily reduced even when at their brightest setting because the front glass is unable to reduce mirror reflections -- the best panels barely go below 5 percent reflectivity. Thus, the company is looking to bring that down to a percentage larger than thin air. The example circle still reflected the sky above, but it was barely noticeable, allowing the green grass underneath to be viewed almost perfectly compared to the rest of the tablet-sized sheet.
In addition to reducing reflections, Corning is also working to incorporate antimicrobial tech into Gorilla Glass that will supposedly kill germs and viruses that can stick on a phone or tablet screen. This will be a coating, and a provided example showed that after thirty minutes, a number of invisible bugs lounging around on the glass were eliminated. After two hours, all bacteria and viruses were wiped clean without user intervention.
That in itself is good news for those who share devices in a home or office. Unfortunately, it may be a few years before consumers see these two new technologies in sheets of glass covering their favorite smartphone, tablet or some other computational or entertainment device that requires touch.
"Corning understands how formulation and fabrication determine the atomic state and structure of a glass. These, in turn, control the mechanical, thermal, and optical properties of the glass," the company said. "Corning’s knowledge of glass properties, and how glass operates in combination with application requirements, allows the company to solve tough customer problems."
The company also provided its 90 second look into a future full of glass, touch and plenty of white called "A Day Made of Glass."
