Japan Display unveils a 5.4'' and 6.2'', 1440x2560 pixel resolution screens
About two months after LG Display revealed their own 5.5'', 1440x2560 screen (538ppi) assembly, and a day after outing a massive 12'' 4K tablet screen running a resolution of 3840x2160, Japan Display has also announced that it's finished with the development of a 5.4'' and 6.2'' screens that both run a whopping 1440x2560 resolution.

As you can guess, these are both aimed for use in smartphones, or phablets, depending on your particular views. The two TFT LCD displays were manufactured using low temperature polycrystalline silicon (LTPS) technology, and offer a pixel density that is pretty much unrivaled, even by LG. The slightly smaller 5.4'' display achieves a pixel density of 543ppi (vs LG's 538ppi), while the 6.2'' giant has the very respectable 473ppi.

To put things into perspective, a 5-inch panel running a 1080p resolution, the current golden spot, has a pixel pitch of 441ppi, lower than even the much larger 6.2-incher, and considerably inferior to the new 5.4- and 5.5-inch screens from Japan Display. Of course, whether the human eye can discern such pixel-dense screens from a now lowly 1080p panel is a whole different story.

In case this hasn't been made clear enough, it does appear that the industry is preparing for the next jump in display tech, and we definitely expect to see quite a few smartphones powering similar panels in 2014. Seeing as Japan Display is a collaboration between Sony, Hitachi, Toshiba and the Innovation Network Corporation of Japan, it does appear likely that a 2014 Xperia may very well be one of the first such devices.

For the full specifications, check the table courtesy of Display Japan right below.

great resolution, rest of the specs not so great, low contrast and poor viewing angles will mean the negatives will out way the negligible visual improvement in sharpness.

Troll detected
u didnt read it??
viewing angles >160
and contrast ratio 1500
read it and then try to troll with good arguments

best viewing angle is 178 and 160 is not so great

Viewing angels are BIGGER than 160 degrees. It could be 178.

Yes, wait till Microkia gets their hands on this.. I'm sure a Lumia device with puremotion, SST, and Clearblack technology will be great... Some are saying that the 1520's 1080p screen may be the best they've ever seen.. I can't wait.

Congrats. you can differentiate 1080p and 720p screens just by looking. Here take your medal.

You care so much about what other people will have in their pockets that it affects your buying decision.

You're the person who gets a weird haircut because everybody else is rocking it. 2 more medals for you.

You guys are funny!
Let's be glad that screen technology is improving, rather than shouting as dogs :)
And let's hope the 5.4 screen will go on the Xperia z2!

41. MistB (Posts: 555; Member since: 07 Jul 2012)


Yep, Xperia Z2 will be getting a 5.4 inch screen with this screen res you can bet. Also the Z Ultra successor I wonder will have much smaller bezels for the 6.2 inch version.

You're one of those idiots who will say that Windows Phone devices with SD800 quad core processors are outdated just because a few months later some no name device is available with s octacore chip.. That's a dumb, and very expensive, way of approaching technology.. You would never believe that the Mazda Miata, with its 4 cylinder engine, is the most raced, and winning car, on any given Sunday... While you keep chasing numbers some of us are more interested in what they actually translate into.. I'm not saying that I wouldn't be interested in a Lumia with a 2-3k screen, bit I'd rather Microkia wait till they can implement a quality unit in the device.. It's not always best, or smart, to be the first person with the newest technology.

I bet no one can distinguish between these screens and 1080p screens at least for 5.4" panel. Even for 6.2" most people won't notice any difference.\

This is an overkill, imo. Innovation is welcome, but really an overkill.

This year's flagship specs are next year's mid-range, so as 1440p screens approach, you'll see Google coming out with an affordable 1080p (any day now), and so it goes with every other HW- the benefit is for the smart and patient.

Oh and BTW 1440p @6.2" is not any sharper than 1080p @4.7". If you dig the HTC One's screen over the One X, you will 1440p over 1080p on a phablet.

Open the same webpage on two different resolution screens and it is crazy easy to tell which has more pixels. Its the screen with more of the webpage visible.

PPI differences are neglible after 400+ to me
But web browsing, picture and text rendering are betr on higher resolution screens always.

For example my 2012 n7 can display maybe 1/3 of a big website at a time with its 720p. But my 2013 n7 can display the same site almost fully on its 1080p screen.

That screen looks gorgeous.
Hope the power consumption is low as well.
The main problem is slim bezels which cause sudden touches.

Common, is technology at its limit and the only way to innovate is with some screen ppi increase? Give us longer battery life. Holographic images, Glasstype smartphones. There's still more than screen resolution. IMO, the next level would be to make the device small and a holographic projection will be seen. Screen should evolve... :)

300ppi... I can make out pixels, 441ppi I cant make out pixels, 550ppi... still cant make out the pixels, so why do I want to give up GPU power and battery life?

So that you can view larger webpages and larger more detailed photos on a smaller screen.

Sony will use this in the future. Just like the Z1 with beefy 3000mAh battery this will consume a lot of battery. Z1 actually failed IMO. 3000mAh battery with only 5hrs of Browsing time. It sucks and i won't buy any sony product again.

that awakward movement when u realize your mobile screen resolution is higher than that of Tv's !!!
resolution beyond 440ppi is insane comm on only now tv resolution are moving from 1080p to 4k and by 2014 we can see 4k screen in mobile
