The Retina Display
In yesterday's iPhone 4 announcement, Steve Jobs shoveled a lot of specs at us, particularly regarding the new "Retina Display." The oddly-named screen - an LCD with a pixel density abnormally high for a mobile phone - seems like it will be one of those features, like the iPad's display, that you have to see to appreciate. The iPad was not that impressive when it was first announced, one may remember, but many people were blown away by the screen when they actually saw it with their own eyes.
The Retina Display's name seems to be either a conscious or unconscious riff on the retinal displays used in virtual reality, where pixels are projected directly on the retina. Steve Jobs also made mention of the fact that the human eye can only discern individual points of light at a density below 300 pixels per inch. This screen, with its pixel density of 326 ppi, is thus supposedly to be as lifelike as a photograph.
Additionally, the Retina Display employs the same IPS (in-plane switching) technology used in the iPad and Apple LED Cinema Display. With IPS, the crystals are aligned horizontally to the screen rather than vertically, which keeps the crystals parallel to the screen. With normal TFT screens, the crystals turn at right angles relative to the surface, which limits contrast, brightness and color definition as you look at the screen from an angle.
This screen also has a much higher contrast ratio: at 800:1, the Retina Display has a 4x greater ratio between the darkest black and the brightest white than the current iPhone. This will give improved detail in dark images and videos, and make text display even sharper when combined with the high pixel density.
Apple says the glass on both the front and back of the iPhone is "Made from the same materials used in helicopters and high-speed trains" and "chemically strengthened to be harder, more scratch resistant, and more durable than ever." We'll have to wait and see, as I'm hard enough on my plastic iPhone... however, "harder than sapphire crystal" is an impressive brag.
So I still think "iPhone HD" might have been a more appropriate name for this device... but given the number of superlatives Apple is tossing around in their marketing, having it be called just a plain old "Four" takes a bit of the bombast out of it.

Fun fact: one pixel on the iPhone 4 is smaller than the width of a human hair

The specs on this display are impressive. I hope it handles well under direct sunlight (a thing where the Nexus One fails miserably).

There's already a phone called "something" HD (don't remember what it is though) but that is why apple didn't name it "iPhone HD"

I cant wait to see this screen in person... Sounds pretty impressive. They only thing I keep thinking of is how this phone will be like after a few months of use. I already see things like hair and lint and that sticky gross black stuff that was on the monkey bars and in McDonald's play lands getting trapped around the stainless steel "antenna." ...Constantly picking at it and tracing the outline of the glass with a toothpick because I have OCD.
And I couldnt agree more with iPhone HD. Thats a lot more impressive sounding than iPhone 4. Maybe they're saving the iPhone HD name for a later iPhone?

So the front and the back of the phone are made from glass? Looks to be aluminosilicate glass, which is actually Gorilla Glass, and it will break if dropped. This seems like a really odd idea for the body of the phone. I wonder how long till we get pics of iPhone 4's that have been dropped and the whole body has cracked.

I wonder who will be the first to try to smash the iphone for youtube attention. I would like to see how much of a beating it can take. I know they had a hard time with ipad.

Take a look here at the stress tests --> Gorilla Glass - ?? - ???? - ????
You can see when they drop the glass it does not break.. it sort of bounces... so its more like plexi-glass than glass-glass. Do you think you're the only person to think that glass on a phone might break? Everyone knows Apple had fun chucking iPhone 4's at the pavement for stress tests to see if that was going to happen. Either that, or they gave a few to AT&T rehab customers who are recovering with Verizon to throw around. ("VERIZON!!"... haha, good keynote!)
And hey, i wonder since its all glass, why not a clear iPhone 4 body? Now THAT would be cool!

Side by side with a 3GS screen:
4 on the left, 3Gs on the right.
