Corning's Gorilla Glass 4 Promises Stronger Protection for Falls Onto Rough Surfaces

Corning today unveiled its new Gorilla Glass 4, its next-generation glass production that is even more resistant than previous versions to glass shattering drops. According to Corning, the company extensively studied shattered screens to understand how and why they break.

Corning scientists examined hundreds of broken devices and found that damage caused by sharp contact accounted for more than 70 percent of field failures. The scientists then developed new drop-test methods that simulate real-world break events, based on thousands of hours analyzing cover glass that had broken in the field or laboratory.

The culmination of this testing was Gorilla Glass 4, which reportedly is two times stronger than competing products and can survive 80 percent of face-down falls onto rough surfaces such as sandpaper. The company also claims the glass retains most of its initial strength following a shatter-free fall.






Corning is long-time supplier for Apple, providing the Cupertino company with Gorilla Glass for its iPhone and iPad lineup. Apple considered using the scratch-resistant sapphire for its iPhone display, but its partnership with GT Advanced fell apart when the supplier declared bankruptcy earlier this year.



Corning says product shipments of Gorilla Glass 4 to customers are already underway, making it a strong candidate for inclusion on next year's iOS devices should sapphire remain an infeasible option.

iPad Air 2 Display Praised for Antireflective Coating, but iPad Mini 3 Display Still Lags

With the iPad Air 2, one of Apple's main selling points has been the improved display, which includes a new bonded construction that eliminates the air gap between the display and the cover glass, as well as a new antireflective coating to reduce glare in situations with high ambient light.



Ray Soneira of DisplayMate Technologies has now put the new display to the test, finding that the antireflective coating is indeed a significant improvement for the iPad and a major step above competing tablets, but in overall performance competitors are still doing better than the iPad. Apple receives only minimal credit for the bonded display, as it is mainly catching up with competitors on that aspect.

A major innovation for the iPad Air 2 (that is not fully appreciated) is an anti-reflection coating on the cover glass that reduces ambient light reflections by about 3:1 over most other Tablets and Smartphones (including the previous iPads), and about 2:1 over all of the very best competing Tablets and Smartphones (including the new iPhone 6). [...]



However, other than the new anti-reflection coating and bonded cover glass, the display on the iPad Air 2 is essentially unchanged and identical in performance to the iPad 4 introduced in 2012, and is actually slightly lower in performance than the original iPad Air (for example 8% lower Brightness and 16% lower display Power Efficiency) – most likely the result of an obsession with producing a thinner Tablet forcing compromises in the LCD backlight.

With competitors such as Samsung, Amazon, and Microsoft offering better color accuracy, viewing angles, and power efficiency, Soneira finds the improvements in the iPad Air 2 insufficient to move the device to the top of his tablet display rankings, and the Samsung Galaxy Tab S retains its number one position.



Moving on to the iPad mini 3, Soneira unsurprisingly finds that the display is unchanged from the one used in the previous generation, unsurprising given that Apple kept the specs of the iPad mini identical with the exception of the Touch ID home button and a gold color option. Soneira notes the unchanged display is a "major disappointment", as the iPad mini 2's display has been rated poorly for color gamut and accuracy.

In 2013 the mini was given a Retina display, but remained with a reduced 62 percent Color Gamut – the only current iPad or iPhone without a full Color Gamut. Now, in 2014 the new iPad mini 3 still only has a 62 percent Color Gamut, plus it was denied the new enhanced anti-reflection coating and bonded cover glass of the iPad Air 2.

Soneira again points to competitors offering higher-quality displays on their tablets, concluding that the iPad mini 3 is "embarrassingly mediocre and way overpriced" considering its $399 starting price tag and significantly poorer display performance compared to both competitors and the iPad Air 2.



Full details on Soneira's testing of the new displays are available in his extensive report.

Apple May Adopt 1704 x 960 Resolution Display for Upcoming iPhone 6

Apple's next generation iPhone 6 may adopt a higher resolution display, jumping from the current iPhone 5s resolution of 1136 x 640 to a sharper 1704 x 960 resolution, reports 9to5Mac. On the rumored 4.7-inch model, this would result in a display with 416 ppi and the same 16:9 ratio of the iPhone 5/5s/5c, while a 5.5-inch model at the same resolution would carry a density of 356 ppi.





With Apple's rumored move to larger displays in the iPhone 6, much discussion has been centered around what resolution Apple will use and how any changes would affect developers. Some speculation had suggested Apple might simply maintain the same resolution as on the iPhone 5s, making a seamless transition for developers. This stretch process would, however, drop the pixel density of the display below Apple's criteria for a "Retina" display.



Alternatively, Apple could boost the resolution to maintain or increase the pixel density, although this move would require work from app developers to maintain compatibility with the new devices. KGI Securities analyst Ming-Chi Kuo suggested last month that Apple would maintain the current 326 ppi density, which could be achieved by bumping a 4.7-inch display to 1334 x 750, and we previously explored how that might work.



But according to 9to5Mac, Apple may adopt an even higher-resolution display that triples the base number of pixels of the iPhone screen in both length and width. This "3x" mode would take the base "1x" resolution of 568 x 320 and expand it to 1704 x 960. Using this method, Apple would retain the Retina branding at 416 ppi and keep the current 16:9 ratio of the iPhone 5/5s/5c.

This means that Apple will likely be tripling the aforementioned “base resolution” (568 x 320) of the iPhone screen in both directions, and that the iPhone screen resolution will be scaled with an increase of 150% from the current 2X resolution of 1136 x 640. Of course, Apple tests several different iPhones and display technologies, so it is possible that Apple chooses to take another route for display specifications for the 2014 iPhone upgrade.

Apple has allegedly been testing this 1704 x 960 resolution and while the design specs for the iPhone 6 are undoubtedly complete, it is not known for sure if Apple has elected to proceed with this resolution. Apple may be preparing to launch the 4.7-inch iPhone 6 sometime this fall with a faster A8 processor and improved camera technology.
