Apple Will Use Glass On Glass Screen Technology For iPhone 7
Due to recent report there is some information about iPhone 7 glass screen. The report states that the Apple company could return to use glass-on-glass touch panels for next year’s line of iPhones. However it will remain using in-cell touch panels for the “iPhone 6s” and “iPhone 6s Plus”.
The glass-on-glass (G/G) technology was first introduced with the release of the iPhone 5 in the fall of 2012. iPhones prior to the iPhone 5 used glass-substrate capacitive touchscreens that form the X-axis sensing electrode on the upper surface of a glass substrate and Y-axis sensing electrode on the bottom.
Starting with the iPhone 5 in 2012, iPhones switched to in-cell technology which eliminates a layer by building the capacitors inside the LCD assembly itself, which let for a notably thinner appearance of the screen and sharper pictures that appear as if painted on the surface of the glass.
The recent report also indicates that Apple is currently sampling glass-on-glass touch samples for 2016 iPhones. If true, then the next year iPhone 6S — or whatever a 2016 iPhone Apple will name—will feature better touch accuracy, improved Multi-Touch performance and better touch detection on screen edges. Notably, the improvement in glass-on-glass production technology could grant Apple the ability to create a bezel-free iPhone that in-cell panels currently limit. The possibility of a full 4K ultra HD screen would also be in the cards according to the sources in the company’s supply chain, again pointing to current limitations on in-cell touch panels themselves, and their production. This will broaden iPhone 7 glass specification usage.
Touch panel makers have reportedly begun sending samples of fully laminated G/G technology to Apple and Corning. Apple supplier Asahi Glass has also reportedly sent glass samples. The Apple company used in-cell technology for the iPhones that will be released in 2015.
