Samsung trashed more than a football field of glass to make the HD Super AMOLED screen on the Galaxy Nexus
It seems that Samsung still used its existing FMM gear, so creating close to a million tiny dots on the screen the size of the 4.65" on the Galaxy Nexus was one of the greatest challenges its Mobile Display unit has faced. A special team called Dalli was formed with the specific task to break the 300ppi barrier above which the average human eye can't discern individual pixels from 12 inches (30cm) - the reason for Apple calling the 326ppi iPhone screen Retina Display.
After numerous sleepless nights the researchers managed to create a metal mask good enough for squeezing hundreds of thousands of organic light emitting diodes in its holes so that they don't smear and enough light passes through for the screen to be bright. Here's what the senior researcher has to say about the whole process:
That's more than a football or soccer field, but the result was worth it, and we are likely to see more results next year when new methods enter mass production stage for the third iteration of the Galaxy S line. Another researcher said: “On the Galaxy Nexus screen, the distance between each pixel is a fifth of the thickness of a strand of hair.”
Creating such a dense AMOLED display with existing production methods was said to be impossible, even by companies like LG. In our own testing of the HD Super AMOLED display tech with PenTile matrix arrangement we indeed concluded that you can't discern the individual pixels from normal viewing distance at such a high density.

Corning didn't make the glass for the Galaxy Nexus?

Corning? You mean Samsung-Corning?
Yup. They have a joint company together

@remixfa: Whoever said the SGN would have Gorilla Glass? Has this been confirmed?

It has been confirmed that the Nexus has reinforced glass that is supposedly equivalent to Gorilla Glass.

exactly.. like car companies crashing and destroying car after gorgeous car in the name of testing and safety!
Love where Sammy is going though.. keep it up!! :)

If they can survive a drop it doesn't matter. I have the Skyrocket and it fell screen down from about a foot on to a hard linoleum floor and cracked the screed. I was stunned as usually it takes the corner drop to bust it.

Ouch!! That sucks bigdawg23!
I guess your Skyrocket dropping experience coincides with Phone Arena's review; their test Skyrocket accumulated scratches just from putting the phone in their pocket and taking it out.
Gotta believe the original S GSII used different and stronger glass.

But still SUPER AMOLED Is a prettier screen than RETINA DISPLAY

Richer colours, deeper blacks, lower power consumption. Its a win-win all round for SAMOLED screens vs SLCD

Small correction: SAMOLED is only better power consumption if it mostly shows the color "black," which implies that particular set of OLEDs is off.
If comparing all white screens on SAMOLED and LCD displays, LCD wins the low-power consumption award.
