Apple Wants Curved Glass

Image source: 9to5Mac.comApple is totally smitten with the idea of curved glass.

The first place we've seen this obsession is in the ceilings of Apple stores. Apple even applied for a patent this week for its curved-glass ceiling design.

In his presentation to the Cupertino City Council last summer about Apple's proposed "spaceship" campus, Steve Jobs, the late Apple founder and CEO, said there wouldn't be a single piece of straight glass in the entire building.

But it's in Apple gadgets where the curved glass idea gets really exciting.

Rumors began circulating in September after Taiwanese magazine DigiTimes reported (registration required) that Apple had purchased hundreds of special-purpose machines for the factory manufacturing of curved-glass displays. Some said the iPhone, or maybe the iPod, would become curved-glass devices.

The most compelling device for Apple would be a curved-glass wristwatch device, which controls other Apple products and interacts via iCloud.

I think it's likely we'll see such a product very soon.

I wrote a column in this space in October about Microsoft's vision for the future of ubiquitous computing, which they illustrated with two videos.

Microsoft's predictions are all based on what current research will make possible or affordable in the future. Many of these ideas are based on major breakthroughs in the cost, quality and functionality of glass.

For example, Microsoft envisions augmented-reality taxicab windows, wall-size displays and computer displays on surfaces like kitchen counters.

A theme is that computer displays can also be see-through. And, in fact, Microsoft developed a prototype for technology that uses transparent displays, called the see-through 3D desktop.

It's a foregone conclusion that transparent computer displays will be cheap and ubiquitous in the near future. I don't believe Microsoft will be directly involved in the making of such products, but many companies will be building innovative smart-glass display technologies that will roughly mirror Microsoft's vision (including smart mirrors).

has already changed the mobile industry. But most consumers don't know the role Steve Jobs had in making that happen.

Corning engineers invented the technology behind Gorilla Glass in the 1960s. At the time, they couldn't find any commercial applications for it so the project just stopped.

Fast forward to 2006. Apple was finalizing materials for the upcoming iPhone, and Jobs was dissatisfied with the hard plastic that many phones, including the iPhone prototype, used for displays. The biggest complaint was that they scratched too easily. At the time, plastic was preferred because glass was considered too breakable for phones.

Corning brought the old '60s project back to life and called it Gorilla Glass. Now, it's the standard for mobile devices and found in 600 million devices.

A new version introduced this year, called Gorilla Glass 2, which is just as strong but 20% thinner, will help smartphones and tablets continue to get thinner and lighter without sacrificing durability.

Corning has another glass technology that could really change things for consumer technology. The new glass is both flexible and very thin. The flexibility enables the manufacturing process to resemble how plastic is made, on factory rollers. It has all the scratch- and heat-resistance of glass.

The company envisions the use of this technology to make wall-size touch displays, for example, and tiny mobile phones that are very thin, light and low cost.

The company also announced this week a new glass technology that kills bacteria and viruses, including scary antibiotic-resistant super bugs. This will be great for medical tablets, and possibly for consumers.

Glass is shiny and causes glare, which makes screens harder to read in bright light. It also reduces the efficiency of solar cells.

MIT researchers this week announced a breakthrough in glass technology that solves the glare problem. The glass has a revolutionary surface pattern made of nano-scale cones of glass.

It's called multifunctional glass. It's very clear, without glare or reflection.

The glass also deflects water, which bounces right off. Car windshields using the glass, for example, would not need windshield wipers.

More interestingly, solar cells under multifunctional glass would be self-cleaning and would enable more light to penetrate through the glass to the cells. It would be easy to imagine a phone like the iPhone 4 line with glass front and back, but with solar sells under the glass in the back.

Smartphones, tablets, laptops and TVs would be essentially self-cleaning. No smudges and no glare!

The researchers are working on a patent and intend to develop the technology for consumer electronics.

What's great about all these ideas and technologies for consumer electronics glass is that they're all about to come to market over the next two years.
