Sharp not even joking, announces 5.5-inch 4K IGZO display with mind-blowing 806ppi pixel density
Like it or not, 4K smartphone displays are heading towards us, and there's nobody left to stop them! After Samsung casually hinted at 4K AMOLED displays for the upcoming Galaxy Note 5, Japanese purveyor of IGZO screens and border-less smartphones Sharp climbed on the stage to announce the world's first 5.5-inch mobile display with a 2160 x 3840 pixels Ultra-HD (4K) resolution. The panel is scheduled for mass production in 2016, and comes with a mind-boggling pixel density of 806 pixels per inch. 

Looking a little ahead, the announcement is made even crazier by the perspective of a non-too distant future, where smartphone displays have reached 8K (4320 x 7680) resolution - that's 16 times as many pixels as ye olde 1080p display, as well as the resolution employed for top-end full dome theater projections! If you think we've finally lost it, well, LG is allegedly making an 8K 27-inch display for Apple, so shrinking it down to phablet-size is a matter of time and technological progress.

Still, it's only 2015, and we're "only" enjoying 1440p resolution displays on our high-end Android devices. You'd be forgiven if you can't quite figure out the practical purpose of 4K smartphone screens, seeing that those 2K displays we mentioned are already considered "overkill" by many consumers and manufacturers alike. While that's perfectly reasonable, we can still see 4K screens offering two very nice, but not necessarily essential benefits. First, they can reproduce 4K video content pixel for pixel, which means extremely sharp and lush visuals fired at your entertainment-hungry eyeballs at a close distance. And second, 4K displays will make VR headset experiences absolutely sublime, as the greatly enhanced pixel density removes the screen-door effect, and therefore provides better immersion. 

Other than that, we can only hope battery technology will catch up with the demands of 4K displays soon enough, as ultra-high definition should not compromise daily usage.

Whats the fking point? You wont recognize the difference between QHD and 4K on a 5.5 inch screen. Only thing this does is reduce the performance and battery life of the device.

Mobile VR headsets.
Next level Android gaming.
Not every phone will have 4K displays.
So there's always options for people who don't want it.
But there should be an option for people who do want it.
For example, people don't like 2560 x 1440 displays on a phone.
There are plenty of 1080 and even 720 alternatives.

Mobile VR headsets.
- So put them in mobile VR Headsets, not phones.
Next level Android gaming.
- What's the point of having all those pixels if you can't notice a difference?
Not every phone will have 4K displays.
- I hope you're right. And I hope there will be flagship phones without 4K displays. The problem is with most phones when you step down from the highest resolution, there is normally a step down in all the specs.

I don't understand the race for ever higher resolution in phone screens. When it comes to technology, I'm not typically one to settle for good enough. If you can no longer distinguish a visual difference from a normal viewing distance, then what's the point?

If there were no negatives associated with it then I'd say who cares. But we've finally gotten to the point where batteries will last a full day under normal to heavy usage. So now let's increase the resolution to use extra power? Again, why, if there is no benefit. Progress for progress' sake is not progress.

Wouldn't you prefer OEMs put money into developing something that you would actually get some benefit from?

exactly!!! also along with screen size.. i know it's more of a caveat to your statement but citing the new Asus Zenfone 2.. the 5.5" version has twice the specs of the 5" version... the market is no longer about "variety" or "choice" again.. if you want the best specs you have to follow the 'popular' option.. even if it's not what you want.

Mobile VR headsets (such as Cardboard)- the phone goes into the frame. 4K displays will be great for areas/cultures where people don't consider flat screens bc of humidity,economic or space concerns (India and southeast asia). This can be a huge driver of technology for people who have different requirements than westerners.

Actually 4K is make sense for those who don't play demanding 3D games. I could read the text better, and since it doesn't do heavy 3D calculation, it doesn't reduce performance. and since it's mostly displaying 'easy' image, it also won't reduce battery life (screen size / brightness level have more impact on battery life)

I guess I didn't realize text was blocky on a 1080p phone. You must have some super insane vision if you can notice the difference between QHD and 1080p on a phone. Superman is jealous!

Unless of course you regularly hold your phone up to your nose. Didn't you're mom ever tell you not to sit too close to the TV? Same comment applies here.

So if there's no 3D processing involved then the higher resolution won't impact battery life? I guess all those pixels get filled for free? Does the GPU not run off of the battery? And yes the GPU is used, whether it's 2D or 3D, though of course 3D would require more processing. Either way your comment is ridiculous!

You're right. But at first, people will say the same thing as yours, but once Samsung's flagship go 4K, people will be like "OMG, my body is ready, Sammy! Can't wait!" and then the 4K trend on phones will begin.

This is how tech goes.

Gonna make 1080 displays more affordable. Let few people have their QHD premium expensive phones so that the majority will have top quality device sporting 1080s with lower prices.

You really think that? in 2016 everything will be different. moreover why not GPU can when SD805 can drive a 4K external display. I can't be certain but SD820 sounds like be the answer to it. (hope SD820 don't curse every OEM who use it like 810 did )

SD820 uses Kyro cores, made by Qualcomm, not ARM cores that are used in fail SD810. Actualy SD820 is the first octacore(4+4) CPU made 100% by Qualcomm.

Games run at 1080p or lower regardless of resolution. I don't think it'll be a problem. Regarding handling UI, it'll be a no problem for even the 810.

Resolution is unnecessarily bashed upon. Even though I agree that there's no point of UHD on a phone, but unless it consumes battery too fast, I find no reason to hate it.

Exactly,
E.g. plug a PS4 into a 60+ Hz 4K TV
It still renders games in 1080p, 900p or 720p, at 60 or 30 fps

Your gpu will be still forced to upscale the textures. So it does impact the performance.

43. material (Posts: 80; Member since: 08 Jan 2015)


it will upscale the 1080p output ,and not the textures individually.

posted on 13 Apr 2015, 07:51

60. TyrionLannister (unregistered)


Upscale barely takes 0.1% GPU. You can derive it. For each second i.e. 60 frames, it has to do approx 200 million integer calculations. Now for any GPU > 200 GFLOPS, this will be less than 0.1 % load .

Upscale takes way less power than actually calculating and rendering textures.

I really hate the 768p resolution, and I think 768p on notebook is like having a 320x480 resolution on a smartphone.

That's what say said when they went from WVGA to 720p, and from 720p to 1080p, and from 1080p to 1440p. And at each step, it turned out to be a non event, battery wise.

Ridiculous how even $1100 laptops come with 1366x768 TN panels and these stupid panel makers are worried about UHD phone displays. I mean for god's sake, my dad has a laptop he paid $900NZD for in 2009 and the screen is the exact same as $1100AUD laptops 6 years later. Laptops displays need SERIOUS innovation...

There are now quite a few laptops with 3200x1800 displays. For example, there are the HP Envy K110nr (or K111nr or K112nr) and the Lenovo Yoga 2 Pro latptops. You can get these for under $800 (I got the HP Envy K110nr for under $600 brand new!) I especially enjoy the HP Envy K110nr display that revealed details in my digital photos that I had never seen before. Plus text is just gorgeous. Nowadays I don't even give those 1366x768 laptops a second look. I am even dissatisfied with my 24" 1080p desktop display - eager to upgrade to 4K when they become affordable (would love 8K even more). I agree with everyone here who is frustrated with the pedantic progress of computer displays whilst mobile displays are making such amazing strides.

Not really. The Note 4 increased battery life over the Note 3 while adding over 70% more pixels but less than 1% more battery capacity.

The other components always get more energy efficient - CPU/GPU, display, ram...Plus software optimizations.
