It is this early history that set our small town in upstate New York on a path to making important contributions to science, technology, communications and more. From the glass envelope for Thomas Edison's light bulb to ceramic substrates for catalytic converters to the primary mirror for the Hubble telescope to optical fiber, Corning has touched lives throughout the world for generations. In fact, the ability to read this piece online is something we had a hand in, too: Corning has helped enable the digital era we live in.
Corning’s Innovation Path to the Digital Era
In 1933, Corning began production of the large glass bulbs needed for cathode ray tubes (CRTs) going into new test equipment, including experimental television sets. By 1948, the demand for televisions had exploded and Corning began its journey into the television market by making key glass components for companies like RCA and Zenith.
In the 1980's, as the digital era was taking off with the proliferation of personal computers and the introduction of low-loss optical fiber, Corning was again at the forefront of the display market, working with our customers to develop and manufacture glass substrates to enable liquid crystal displays (LCD). To produce the incredibly flat glass needed for flat panel LCDs, Corning introduced the fusion-draw process. Corning was the first manufacturer in the world to form specialty glass in this way. Fusion-draw produces untouched and pristine glass surfaces, eliminating the need for polishing. We later used the same technology to enable laptops, smartphones and other immersive displays, which brings us to the advent of Corning® Gorilla® Glass.
Thirteen Years of Gorilla® Glass Innovation
In 2007, a new challenge was brought to Corning – Steve Jobs was looking for a tough new glass that could withstand lots of abuse for Apple’s soon to be released iPhone. Oh, and by the way, we’d need to be up and running at scale in 6 months. We all now know how ubiquitous the smartphone would become, with a surface that requires incredible clarity and touch sensitivity, but also durability since people touch and swipe their handheld device on average 2,000 times per day. To respond to the challenge, Corning took lessons from glass formulation and strengthening techniques from the 1960’s and developed a new formulation. Our history of research, product experimentation and manufacturing excellence allowed us to “get lucky” again. Over 8 billion devices later, Corning’s invention of this new category of strengthened cover glass has turned out to be quite a good response to that initial challenge.
As more and more of our lives moved from analog to digital, more and more people looked to their smartphones to help them live their daily life. These handheld computers have become indispensable to consumers around the globe. Early on, we recognized the importance of continuous innovation in our glasses to keep pace with, and in many respects to enable, smartphone design innovations. And as designs evolved, consumers demanded even more from their devices as well. Our improvement efforts focused on scratch resistance with Gorilla® Glass 3. As devices got bigger and thinner and saw more constant use, we shifted our focus to include drop performance as well. Our Gorilla® Glass 5 and Gorilla® Glass 6 innovations pushed the envelope on what was possible on the front, as well as, the backs of phones. Rest assured, our innovations in this space continue — which brings me to an exciting announcement.
