Hitachi Offering Super-Advanced Mobile LCD

Hitachi has just announced that it will begin churning out new LCD displays for mobile phones which are on the “limit of what is discernible to the human eye.”

So that’s it then, all other manufacturers can pack up and go home, Hitachi, or to be correct its subsidiary Hitachi Displays, has come up with a super-bright, super-clear 4.5in IPS LCD display which has a resolution of 720 x 1,280 - and anything better will make no difference. Hitachi Display has managed to pack in 329ppi into it small frame. In a release, Hitachi said that the proliferation of smartphones and in particular content such as HD video and photo-quality books being consumed on them, highlighted the need for such a display.

While the numbers above may mean nothing on their own, when compared to the highly-praised Retina Display from the iPhone 4, we can see just how good these displays will be. The 3.5in Retina Display has 960 × 640 resolution, 326ppi and a 800:1 contrast ratio compared to Hitachi’s 1,100:1. Hitachi announced that it expects to begin churning out the mobile displays by October and will have it on display at a trade show in the States in May.

We can expect to see this display in smartphones, superphones and 3D phones by this time next year and we imagine that if you come to CES 2012 without one of these displays in your mobile phone then you may as well stay at home.

I can't see that 3ppi will make a huge difference over the retina display. The brightness/contrast might though.

The resolution sounds great but 4.5" is too large for a smartphone and while the size, resolution, brightness & contrast may be headline grabbing there's no mention of it's efficiency.

I'd like a screen size that I could fit in my pocket (4" at most), with the same ppi, great brightness and contast, and readable outside in daylight, but the battery to last a lot longer than half a day if I wish to use the phone!

Haha! Walk up to Jenson Button and tell him it's in the news that his McLaren WILL be 1 millisecond a lap slower than Lewis' ALL season, and see if he shows up for racing when season starts ;)

Samsung surely have something lined up soon as well?

when will we see/will we need/ as high pixel densities for monitors

Nice. We still won't be able to see anything in sunlight though.

If LCD manufacturers have maxxed out on the resolution, it's time they started innovating in other areas - like visibility in daylight.

LCD is still the best technology for daylight readability, mind you. Beats AMOLED hands down. It would be nice to see some progress towards practicality, of course, but then I get the impression that it's not for a lack of trying.

Yes folks I know. However it does have one huge technological advantage. It will contribute big time to removing the smug smile from a certain customer groups faces!

This sounds like the perfect size and resolution for a top-end mobile. I would definitely buy a phone with this display!

Agreed that it would be perfect for Remote Desktop :)

Nice though it is, I'd much rather see 16 x 10 or more, rather than 16 x 9. My Dell Streak is approx 16 x 9.5 (800 x 480) and it's simply too narrow at times when typing in landscape orientation; there's not a lot of screen left when the keyboard is active. I'd prefer it to be wider in portrait orientation, too.

16 x 9 only works for films, everything else needs something far more square. Apple appear to know this as the ipad is 4 x 3 and the iphone 4 is just over 16 x 10.5.
