CORNING INC.: New Corning® Gorilla® Glass Technologies
Corning Gorilla Glass 6, Corning Gorilla Glass DX and Corning Gorilla Glass DX+ reportedly offer improved cover glass performance.
Corning Inc. recently introduced several Corning® Gorilla® Glass technologies. According to the company, Corning Gorilla Glass 6 is its most durable cover glass to date.
“As consumers become more dependent on their smartphones, the opportunity for potentially damaging drops is also on the rise,” said John Bayne, vice president and general manager, Corning Gorilla Glass. “Now more than ever, it’s critical that the cover glass provides outstanding protection. Corning Gorilla Glass 6 improves upon Gorilla Glass 5 by surviving drops from higher heights, but, more importantly, has been engineered to survive multiple drops.”
A recent worldwide Toluna consumer study revealed that, on average, people drop their phones seven times a year, with more than 50% of the drops occurring at 1 m or below. To improve cover glass performance, Corning scientists developed and engineered a new material to address the challenge of multiple drops. On average, in lab tests, Gorilla Glass 6 survived 15 drops from 1 m onto rough surfaces, and is up to two times better than Gorilla Glass 5. Under the same test conditions, competitive glass compositions, such as soda lime and aluminosilicate, did not survive the first drop.
“Gorilla Glass 6 is an entirely new glass composition that can be chemically strengthened to give it significantly higher levels of compression than is possible with Gorilla Glass 5,” said Jaymin Amin, Ph.D., vice president of technology and product development, Corning Gorilla Glass and Corning Specialty Materials. “This enables Gorilla Glass 6 to be more resistant to damage. Moreover, with breaks during drops being a probabilistic event, the added compression helps increase, on average, the likelihood of survival through multiple drop events.”
In addition to larger front displays with more surface area, mobile device manufacturers are also embracing phone designs with glass backs. These designs are providing new features and applications for consumers, such as enhanced wireless charging, larger screen sizes with smaller bezels, and customization through printed glass backs. With its optical clarity, touch sensitivity, scratch resistance, efficient wireless charging, and enhanced durability, Gorilla Glass 6 is reportedly poised to enable these new design trends. Corning Gorilla Glass 6 is currently being evaluated by multiple customers, and is expected to reach the market in the next several months.
In addition, both of the new Corning Gorilla Glass DX and Corning Gorilla Glass DX+ glass composites feature an antireflective property that reportedly improves optical clarity and superior scratch resistance scaled to consumer needs. An extension of Corning Gorilla Glass SR+, Gorilla Glass DX and Gorilla Glass DX+ glass composites can be used in combination with Corning’s Gorilla Glass products to best address mobile device manufacturers’ design priorities. While currently being adopted primarily for wearable mobile devices, developments are underway to adapt these new glass composites to larger form-factor devices.
“We have surveyed more than 85,000 global consumers* over the past seven years, and we discovered that nearly 50% cited readability as a highly desired feature in a cover glass,” said Scott Forester, division vice president, Marketing and Innovation Products, Corning Gorilla Glass. “But we also know that consumers don’t want to sacrifice the scratch resistance and durability that they’ve come to expect. Gorilla Glass DX and Gorilla Glass DX+ address this challenge by delivering outstanding readability combined with best-in-class scratch resistance and the inherent toughness of Gorilla Glass, making them ideal for today’s advanced mobile displays.”
Gorilla Glass DX and Gorilla Glass DX+ both enhance display readability by improving the front surface reflection by 75% vs. standard glass, and increasing the display contrast ratio by 50% with the same display brightness level. These improvements in optical clarity can also lengthen battery life.
A point of differentiation between the two solutions is in the levels of scratch resistance. Gorilla Glass DX features enhanced optics with the same scratch resistance of Gorilla Glass, while Gorilla Glass DX+ provides enhanced optics with superior scratch resistance approaching that of alternative luxury cover materials.
