A diamond glass display could be a smartphone owner's best friend

A diamond glass display could be a smartphone owner's best friend
Before this year comes to an end, you could be purchasing a new smartphone sporting a display made from diamond glass. Remember when there were rumors every day about the Apple iPhone 6 using a sapphire crystal display? Back then, we would constantly tell you that diamonds are the hardest material in the world, followed by sapphires. But there are more advantages to using diamond glass than just its hardness. According to Adam Khan, CEO of Akhan Semiconductor, diamond glass does offers the strength and protection as you would expect, but it also will provide a cleaner screen than anything you've seen before. Khan's company grows diamonds for electronics.

Due to the lack of supply, Khan is offering his company's Mirage Diamond Glass to one smartphone manufacturer, one wearable company, etc. Another reason to limit the use of his product is to allow the companies employing it to crow about it in advertisements. Right now, the company plans to produce enough diamond glass for 10 million to 30 million phones, and less than one million wearables. That would limit the use of his diamond glass to a smaller manufacturer, at least at first.

Pricing of a phone using diamond glass would no doubt be at a premium level. The HTC U Ultra model with a sapphire crystal display is priced in Taiwan at the equivalent of $920 USD. That compares to the price of $749 for the device with a Super LCD 5 display. But for those who regularly drop their phones and crack their displays, paying more might be worth it. Adding diamond glass with Gorilla Glass makes the screen on a smartphone 6 times stronger and 10 times harder, according to Khan. It also could help make the electronics inside a phone run over 800 times cooler.

It's funny how iphonearena always have to mention iPhone in all articles.

That'll be the next big step over Gorilla Glass 5...let's see what Samsung puts on the Note 8's screen this time.

This just sounds like BS PR. Show us the goods. Usually harder means more brittle. And "800 times cooler"?! Just that statement alone disqualifies this as serious science.

Harder doesn't directly mean better though, can also become more brittle course depending on a lot of factors.

There is an argument to be made that says it does but I don't feel like getting into it.

Was more meant as a 'its harder its better' counter, it can easily BE better but there's more to it, then it simply being harder.

I agree. It's one thing to resist the impact force and another to absorb and distribute it. The tech behind the screen itself can withstand multiple hammer blows, but the substrates on top can't bend like the screens can.

Didnt you go to school? Harder does mwan more britrle, which means it will break easier. Remember GG5 is a bit softer so it less likely to break. There are several sites online where engineers who considered using diamond material to make smartphone glass, themselves stated. Its better on a smaller device with less surface area, like a home button, watch screen, camera glass and similar. Bit not a display om a phone. And with pjones not having sides its going to break. Its still glass. Glass breaks, no matter how thin or thick. With fools doing stupid drop tests ,which dont prove anything other than only an idiot would drop a $700 phone.

Yes I did and I know that diamonds are brittle. We no nothing about the process used to create these screens and we no nothing about its properties, perhaps this company has cracked the secret to making diamond displays that aren't so brittle. This is why I said I didn't want to get into it because there isn't enough info on the screens to decide if they are good, bad, soft, brittle, or wherever else you might want to know about them. They are advertising this screen as one that will not break (or very hard to break) so you can't just assume what you said in your first sentence will be true.

Don't you walk into your glass door all the time tho?

Not sure if actually a serious question or merely kidding around...if the former, it takes a certain amount of force to break anything. The force exerted on the screen of a phone, when it makes impact with the ground is nowhere equivalent to the force of you walking into your glass door (that's significantly less). Plus, your glass door is significantly thicker than a smartphone screen, which further increases the amount of force required to break it... TLDR: Several factors to take into consideration.

Apparently he uses the glass door to type on his phone, I mean look at all the typos!

Wrong, techie. While diamonds are both harder (4x) and more brittle than a sapphire, a sapphire is both harder and less brittle than a topaz or a zircon. I'm big into precious stones, and many seasoned stone setters will tell you just what I told you. The tough and hard stones typically can stand the pressure and abuse of setting in bezel, channel, and tension settings whereas others cannot. Many metalsmiths will not put anything short of corundum or diamond in a tension setting. Brittle characteristics typically come from irregularities in the crystal lattice or an inability of one grain to slip past the boundaries of another, depending on what type of material we're talking about.

Furthermore, diamonds have what is referred to as plane cleavage. What this means is that a diamond is very tough from certain angles, but susceptible to breaking from others. Diamond has what is called perfect cleavage, as an entire field of carbon atoms will split from another in a regular and smooth pattern. Sapphire, actually, has no cleavage on any plane. The amount of force needed to cause a standardized piece of sapphire to snap is actually higher than what is required with the same dimensions in glass. Sapphire isn't as brittle as you or Corning would try to make it out to be. As a side note, Corning is selling a fancy mixture of soda glass, so things aren't the same. Soda glass is more flexible than normal glass.

It's sad to see sapphire not happening

I'll pay 10k for a phone with diamond display.:)

So if my phone runs at 30° Celsius, what would 800x cooler be?

"-26 degrees celsius" - The ideal temperature for the Snapdragon 810.

The article states in the last line "It also could help make the electronics inside a phone run over 800 times cooler". That sounds like a too good to be true kind of statement to me.

2017 and people still think that diamonds are rare and expensive. Any chemists know that you can create diamonds as strong as the natural mined types.

This is absolutely true. We already know how to make diamonds in laboratories, big enough to cut into faceted pieces. While many lab made stones have distinctive growth characteristics that a seasoned geologist can use to differentiate them from naturally grown specimens, lab grown diamonds are so similar to the natural counterpart that it is mandatory under law to laser engrave the stone's girdle with identification that it is lab made. Diamonds sold in the West are a racket if I've ever seen one.

Imagine a Note 8 with diamond screen at premium price and after two years the display starts showing Burn-in and the non-removable battery life degrading 50% shorter
