Japan Display shows off 5.5-inch, Quad HD display: could this be the display in the iPhone 6?

JDI's 5.5-inch Quad HD display panel

JDI's 5.5-inch Quad HD display panel

Japan Display (JDI) has announced that it’s developed a Quad HD (2560 x 1440-pixel) display, and it's ready to start mass production in April. The panel measures 5.5 inches, and it will be manufactured using JDI’s improved low-temperature poly-silicon (LTPS) technology that enables low power consumption of the module.

The big question lurking around this announcement is whether this could be the screen Apple uses in its next iPhone. Coincidentally, the alleged iPhone 6 is - so far - rumored to come in a 4.7-inch and a 5.5-inch version (sized just like that JDI panel). However, size is not the only reason that makes JDI's 5.5” Quad HD panel seem like a good fit for Apple's next big thing. Such a panel also matches recent reports from the Tokyo-based Nikkei publication, saying that Apple will rely on Japan Display (among others) for the displays of the alleged iPhone 6.

Nikkei also says that volume production of LCD displays for the upcoming iPhone is expected to start in the second quarter of the year (beginning in April) at Sharp’s Kameyama factory, Japan Display's Mobara manufacturing plant, and at an unknown LG Electronics factory. This timeline, again, matches JDI's current announcement.

At the same time, though, practice shows that Apple prefers to get parts that don’t have such wide publicity, and it would be very atypical if a component, that’s unveiled months ahead of the expected September launch of the iPhone 6, actually ends up in that final Apple device (or devices). Summarizing it all up, we’d say that - while it seems possible for Apple to use this 5.5” JDI display - it’s still only a speculation that should be taken with a grain of salt.

On top of that, we also ought to mention that Japan Display had already earlier unveiled Quad HD displays sized at 5.4 and 6.2 inches, but this 5.5-inch panel seems to be the first going into mass production. While big brands the rank of Samsung and Apple have not officially announced devices with Quad HD screens, Chinese phone makers started unveiling products with such high-res panels back in December (with the Vivo Xplay 3s). Putting the pieces together, we could well see those Chinese brands get the first shipments of the new high-res displays.

Specifications:


Screen size (diagonal)5.46-inch (13.87cm)
Number of pixels1440(x RGB) x 2560 (WQHD)
Resolution density538 ppi
Dimensions70.94 mm (W) x 128.26 mm(H) x 1.35mm (D)
Dead-bandTop 1.0 mm, side 1.0mm, bottom 5.4 mm
NTSC ratio70 %
Contrast ratio1000:1 (Typ.)
Viewing angle>160 degree (CR>100:1)
Surface luminance450 cd/m2 (Typ.)

Going back to the Apple side of things, we should also say that we've heard whispers about a 4.7” iPhone 6 panel being in the works. Speculations fly around that it could use a 1600 x 900-pixel display, and that would be, again, a much higher resolution than the current 1136 x 640-pixel one of the 4-inch iPhone 5s. As is often the case with Apple, though, you never know until the very last days, so brace yourselves with patience.

If the battery is right then by all means go for it iPhone. But I doubt it ever since iPhone started battery is one of the main concern.

Not only the battery is going to be an issue but another big issue is instead of calling it a QHD display, apple will have change the QHD to something that sounds cool. Probably retina2 tech....I don't know

They wont be able to rename it though will they? As the tech does not belong to them unless they buy the patent right to the development, or at least that is my limited knowledge of patents. I thought they developed or at least worked on the retina displays development,

They already rename other people's LCD screen to the retina thingy.

Retina display is merely a name. That's all it is. All the consumer knows is a high PPI count. Of course compared to what other phone manufacturer produce today trounces the data Retina branded offerings, it still works at wowing the uninformed consumer

It is possible that Apple is going for QHD displays. They were the first to introduce Retina displays (a resolution so that human eyes cannot perceive pixels anymore). But then Apple kept this resolutiion for their 4 year design cycle. This cycle ends 2014 and therefore, we can expect that Apple will introduce a big change concerning screen, ram and battery this year. These changes will then more or less stay the same for the next four years. I dont think that battery size will be such a great issue since the iPhone 6 is going to be larger in general. The reason why Apple has a relative small battery right now, is that the iPhone is a small smartphone.

Retina displays don't have a high enough ppi our eyes can perceive more pixels.
thats why if you are used to sharper products (one/z1/s4 etc.) you just can't go back to an iphone without seeing the pixels for a couple of hours/days.
and probably its will be the same thing when 4k hits.
im not sure about 2k (QHD)

That depends on how close you zoom in I think. When I read some stuff on the internet, I cannot see any pixles when zooming in as much as the iPhone supports it.

It depends on how close you hold your phone to your eyes.
at 12 inch you(if you have good eyes) can see around 471 ppi at 8 inch around 716 ppi.
There are others saying the eye could see up to 2000+ ppi.
And some are saying the same thing that apple says.
But in my own experience i can see the pixels on the iphones so its a no go for me.

I agree, Apple won't care about trying to beat Android in terms of pixels.

If Apple did, then it would be 2272x1280 (4x 1136x640) because Apple likes to try make it easier for developers to port older apps to the new res and so un-update apps don't look too bad.

Well the iPhone 5 finally caught apple up to the rest of humanity by making it 16:9 aspect ratio so they don't have to use weird resolutions anymore.

The problem is Apple made such a big deal of the silly "retina display" term, and if they do indeed increase size to these dimensions, they're going to drop under 300ppi unless the increase resolution, and have to either redefine it or drop the term.

Of course, Apple knows that is core, rabid fans will eat up whatever the dish out and proclaim it gourmet, but they want to continue growth. We saw with the iPad mini OG that retina doesn't matter to that group. And there's no denying that the A7 would handle QHD as well as any current or near future mobile SOC, so the A8 undoubtedly will as well.

Using simple algebra we get:

4.84" display with 2272 * 1280 resolution with 540 PPI.

This would be the best solution for the iPhone 6 both from a software and PPI standpoint.

Apple is the first to use display resolution higher than WVGA in smartphone. So, there's always a possibility. CMIIW

Wrong. Apple isn't the first to use resolution above wvga. Sharp already had a phone at 333ppi in 2006. Apple only started 'retina' with the iphone 4 in 2010. Have to credit Apple for making other manufacturer's increase their ppi.

if they would use QHD screens it would be great as that is the biggest let down. i think that is also a reason why people are moving to android. if they at least use a hd screen it would be a big step forward.

1600 x 900 is super disappointing. I'm not an Apple fan by any stretch of the imagination, but HD+ might actually anger Apple fans.

No matter what, Apple will call it the Retina+ or something and people (noobs) will still think that it's better than any Android. That is what Apple noob brainwashing does to people.

Hopefully this is for Sony's next flagship. Considering it's made by JDI.
