Corning’s new generation (Gorilla Glass 4?) of thin and durable glass is expected to pack new features that may make Dragontrail and even the superbly durable sapphire glass appear inferior. This time, it’s not just a solution similar to oleophobic coating, Nokia’s ClearBlack display polarizer system, or Sony’s OptiContrast design. The new Gorilla Glass itself will have significantly lower reflectance compared to every other glass used to cover the displays of mobile devices.
This anti-reflection technology was already hinted at by Corning’s director for marketing and commercial operations at the Computex expo in Taipei last June. Now, the company has a convincing demonstration of the kind of dramatic reflectance reduction its new glass will offer.
At the MIT Mobile Technology Summit, Corning’s senior vice president and operations chief of staff, Dr. Jeffrey Evenson, presented the evident effect of the company’s new technology in reducing the reflectiveness of glass. He showed an image of a thin sheet of glass that appears to have a hole at its center. The hole, as Evenson revealed, turns out to be the portion coated by Corning’s new anti-reflection solution. There was actually no hole on the glass! It was an optical illusion that demonstrated the kind of technology that would seem to be the perfect solution to the visibility limitations of most displays outdoors, under bright sunlight.
Every glass-covered device on the market suffers visibility problems under the sun. Even the devices touted to have the highest display brightness and contrast can’t adequately compensate for the reflectivity of the tempered glass used to cover them. With Corning’s new technology, the future of better outdoor display visibility looks assured.
Going beyond clarity, here are a few highlights of Corning’s latest products:
- The glass can withstand an enormous amount of pressure, at 10 gigapascals. That’s equivalent to the weight of 10,000 elephants stacked atop an area covering that same theoretical elephant’s foot.
- Glass is essentially super-cooled liquid, so regular glass “flows” and “sags” after time. In contrast, Corning’s glass will take 20 trillion times the Earth’s age to show a visible sag.
- Glass is impermeable, especially compared with plastic. Corning explained that a molecule of oxygen can pass through a one-millimiter thick piece of plastic in two weeks’ time. Its glass? About 30 billion years. Since water and oxygen are enemies of OLED and other advanced display technologies, Corning says its glass is the best enclosure for these displays.
Not that you’re going to let an elephant dance atop your smartphone screens, but these only show how strong Corning’s glass is in terms of compressive stress. Now as for impact resistance and bending, that’s a different thing altogether.
No more filthy touchscreens
Even better, Corning also presented their antimicrobial solution to filthy mobile devices. The upcoming Gorilla Glass will come with a …read more
