Casio/Toppan HAST Screen OrtusTech

Apple boasts that the "Retina Display" on its new iPhone 4 packs in more pixels per inch than the human eye can identify, at 326 ppi. This new screen, from Casio and Toppan Printing, crushes it with a whopping 458 ppi. The real loser here: our suddenly inadequate-seeming eyes.

Of course, Apple's claim is sort of dubious: maximum perceived pixels per inch isn't a constant number. The closer you are to a screen, the more pixels per square inch you can see. But clever marketing terms aside, this new screen (a collaboration between Casio and Toppan Printing) is a pretty amazing achievement. At only 4.8 inches, this little screen is the smallest ever to achieve a full HD resolution of 1920 x 1080. Apple's retina display, which along with Samsung's Super AMOLED screens found on the Galaxy S smartphones is just about the best small scale screen around, clocks in at 960 x 640. (Those would be normal-sized pixels, not nano-pixels.)

The new display is a type I've never heard of, termed the Hyper Amorphous Silicon TFT, or HAST. It supposedly offers a 160-degree viewing angle, 16 million colors, and is up to 30% brighter than competing TFT displays. We haven't seen one in person, but the promise of that much pixel density is really enticing--this looks like one very sharp little screen.

There's no word on when (if ever) the screen would show up in any kind of gadget we could buy. The size, 4.8 inches, is sort of an awkward in-between size, too big for a smartphone but much too small for a tablet, and we don't know anything about its size or power consumption. But that won't stop us from pining for a full 1080p screen in our pockets in the near future.

Another funny useless mobile phone.
Check article in POPSCI "Electrocardiogram-Equipped Cell Phone Allows Remote Monitoring".

I would love a 4.8 inch 1080p screen on my smartphone.

I'd settle for 1080p on my netbook.

This is perfect personal media player size. I would love this baby on an archos.

TXsam and Dirk. 1080p on anything less than a 40 yes that is FORTY inch TV is pointless. If you have a 32 inch 720p and a 32 inch 1080p tv sitting right next to other the human eye simply can not tell the difference. like Apply says, even its new screen is pretty much overkill. and its only half 1080p. At that stage the next step will simply be to make the screens thinner and cheaper and higher res.

The *REAL* loser ... B A N D W I D T H ! ! !

You are just gonna waste time buffering content or paying extra for monthly bandwidth charges.

I am typing this comment on a 52" Inch 1080P/120Hz monitor, which is 6 feet from my face. ... I usually have my nVidia drivers set for 720P (readability) for browsing/surfing and only up-rez when photo-touching or editing HD content (while seated closer to the monitor).

Most network HD content is shot and broadcast at 720P.

Dude I hook my computer up to my 65"
DLP 1080P and 3-D that fool out! I don't care what you all say there is a diff between the displays going from 720p to 1080p I garuntee you can tell the diff from this display next to an iphone whether your eyes can see it or not. YOu would be surprised at what you eyes can't see and the brain recognizes.

Someday, people will wake up and say, "Watching Avatar on a 4.8" screen is ridiculous!"...

The real loser: Tmobile. For losing over 3 million customers data on sidekicks. Done with tmobile!

I wont' ever let them forget it!
