gorilla glass

The GTAT mess may have forced Apple to abandon its presumed plans to replace iPhone Gorilla Glass screens with sapphire, but next year’s iPhone displays could still prove up to twice as shatter-resistant, says glass-maker Corning.

Corning said that studying hundreds of broken phone screens had revealed the unsurprising fact that shattered screens most commonly occurred in a one-meter drop onto a rough surface like concrete or asphalt. Drop tests in these conditions found that Gorilla Glass 4 survived up to 80% of such impacts – twice the record of the Gorilla Glass 3 used in current iPhones.

While there was much scientific testing behind the scenes, the videos the company used to illustrate the improved strength were rather less scientific in nature …

Good Technology is out with its latest report examining share of mobile platforms in the enterprise and in it noted that iOS was able to grow its market share following the introduction of the new iPhone 6 and 6 Plus. The increase from 67% last quarter to 69% during Q3 isn’t a huge one, but it’s notable given it comes at the expense of Android OS just over a month into sales of the new Apple devices.

Time is reporting that, in contrast to the many rumors (and GTAT investor claims), Apple had never planned to use sapphire displays for the iPhone 6, and the company may not use it for future iPhones.

Some reports stated that up until a few weeks before the iPhone announcement, Apple was going to use sapphire but dropped it because of yield issues. This is not true. My sources tell me that sapphire was never targeted for the iPhone 6 or 6 Plus and its role in future iPhones hasn’t even been decided yet.

Speculation about sapphire displays for the iPhone 6 began when Apple built a major new manufacturing facility in Arizona last November. But Time‘s Tim Bajarin says that while the scratch-resistance of the material may have made it sound superficially appealing, there were no fewer than five reasons it would not have made sense to use the material for the iPhone 6 display …

An investment note we’ve seen from analyst and GTAT investor Matt Margolis claims that all 5.5-inch models of the iPhone 6 will come with sapphire screens, while the 4.7-inch model will get either sapphire or Gorilla Glass depending on the specification.

According to sources close to Foxconn’s manufacturing operations the iPhone 6 will come built with sapphire cover screens in both sizes. These sources have also indicated that the 4.7” Phone 6 is being assembled in two varieties, a sapphire cover screen version and a version featuring Gorilla Glass. At this point I do not know the approximate mix between the two cover screen options on the 4.7” iPhone 6. My latest check on the 5.5” iPhone 6 indicates that all units of the device are expected to come protected by a sapphire cover screen at this point …

Last week, YouTuber Marques Brownlee got his hands on what is claimed to be a sapphire glass panel from Apple’s upcoming iPhone 6. The initial video (found here) put the panel through a variety of torture tests including, knives, keys, and even a flexibility test to show off the panel’s durability. While there were no scientific tests performed to prove the front glass is actually sapphire, the result of each test was very impressive. Well, apparently that wasn’t enough…

While it’s not yet certain that the iPhone 6 screen will get a sapphire layer, that’s certainly the way things look at present – providing a screen that is pretty much impervious to scratches (though no more resistant to breakage).

The problem with sapphire is it’s about ten times as expensive as Gorilla Glass. There have been vague suggestions that new manufacturing techniques might narrow the gap, but it still seems likely that Apple will have to sacrifice a bit of margin to introduce the material.

That’s likely a cost the company can afford, given the marketing benefit of an effectively scratchproof screen. But will we also see sapphire screens on iPads … ?

A report published in Taiwan’s Economic Daily News, via Mac Otakara, reiterates the flurry of previous reporting that Apple will release two new iPhones this year with larger displays, around 4.7 and 5.6 inches respectively. This has been reported countless times in the past by multiple sources. It also says that Apple is targeting a release in the third-quarter, again unsurprising at this point.

However, the report goes onto say that only the larger of these two phones will feature sapphire-glass. According to this sketchy report, the 4.7 inch model will continue to use Corning’s Gorilla Glass like the current iPhone 5s and 5c.

There has long been speculation about Apple incorporating a solar panel into its products, both for environmental reasons and to boost battery-life. There have been Mobile-Solar Apple Jobs that have vanished after discovery, tons of patents, trial rumors and of course the Solar effort/expertise on Apple’s Data Centers and new Campus 2 building. This week, Seeking Alpha has a highly speculative piece by Matt Margolis suggesting that the evidence may be mounting for the iPhone 6 being the product Apple uses to bring the Solar idea to market.

Before we get too far into the speculation, it is worthwhile to note that the surface area of an iPhone would hardly be enough to keep a charge let alone recharge a phone even with the most efficient solar technology in labs today. However, all of the evidence weighed together might make you forget all of that ‘science’…

An intriguing patent application by Apple to deliver mood-based advertising contains what could be read as a strong hint that the rumored iWatch will, as we’ve speculated in the past, major on sensor technology.

In addition to describing ways of assessing mood by such clues as likes in social media, type of applications used and music playing, the patent also lists physical characteristics that could be used:

Mood-associated physical characteristics can include heart rate; blood pressure; adrenaline level; perspiration rate; body temperature; vocal expression, e.g. voice level, voice pattern, voice stress, etc.; movement characteristics; facial expression; etc …

In an effort to combat spreading germs and bacteria through sharing smart phones and touch screen devices, Corning announced today plans to produce a Gorilla Glass variant with an antimicrobial surface for inhibiting bacterial growth. This version of Corning Gorilla Glass is made up of an antibacterial agent and contains levels of ionic silver that sustains the germ fighting capabilities through the life of the surface, according to the company.

Research firm IHS, which previously dismantled the iPhone 5s and 5c to calculate component costs, has now done the same with the iPad Air.

It concludes that while the technology in the iPad Air is significantly more advanced than in the iPad 3 (for some reason the company skipped the iPad 4), the total production cost is actually lower, reports AllThingsD.

The firm says Apple’s iPad Air […] costs between $274 and $361 to build depending on model. The […] total component cost of the base model, at $274, is still $42 cheaper than the entry-level third-generation iPad …

One of the many Apple Television concepts out there (image: theverge.com)

Among the less likely of the many rumors surrounding  Apple’s long-expected move into full televisions is one reported in Bloomberg today, suggesting that Apple will launch 55- and 65-inch 4K televisions in the final quarter of 2014 with pricing in the $1500 to $2500 range.

Masahiko Ishino, an analyst at Advanced Research Japan Co, claims the displays will be made by LG, the GPUs by Samsung and the frameless glass cover made from Corning Gorilla Glass 3, with Foxconn assembling the products …

In case you needed some proof that the rumors of Apple switching from Corning glass to sapphire crystal are unlikely, Corning has posted a video on its website showing how its current Gorilla Glass is superior to sapphire for mobile devices.

Recently, speculation has arisen that manufactured sapphire crystal might become an alternative to Corning’s Gorilla Glass.  “Sapphire’s performance as a cover for high-end watches probably leads to the current speculation.  But those covers are much smaller than a mobile phone and are two to three times thicker than Gorilla Glass.  In one of our commonly accepted strength tests, sapphire breaks more easily than Gorilla Glass after the same simulated use.  Additionally, sapphire’s cost and environmental hit are huge issues,” Steiner said.

There have been a couple rumors floating around that smartphone makers are looking into using sapphire crystal as a replacement for other cover glass solutions. With Apple using the material as a cover for its camera lenses on iPhone 5 and the latest iPod touch, some have speculated it could use sapphire for other parts of its devices, such as the display’s cover glass or home button. However, that’s not likely, according to Corning, Gorilla Glass is “about half the weight”, requires 99 percent less energy in manufacturing, provides brighter displays, and “costs less than a tenth” of sapphire.
