LG QHD panel

Not content with launching a smartphone with a 5.5-inch QHD display, LG said that it will be demoing a 6-inch QHD panel at next week's Society for Information Display's (SID) Display Week 2014 in San Francisco.

The 6-inch QHD display will feature a pixel density of 491 ppi, which in itself is higher than what the Galaxy S5 (432 ppi) and HTC One M8 (441 ppi) boast. While LG was able to break the 500 ppi barrier with the LG G3's 534 ppi display, the South Korean manufacturer is aiming for loftier goals.

A senior researcher at LG Display mentioned in an interview that development was underway on 600ppi and 700 ppi smartphone panels. He stated that LG was at the forefront of pixel miniaturisation, and that it would be difficult for its competitors to catch up without significant resources. While a tentative timeline was not provided, LG has said that higher resolution displays would make their way onto phablets and smartphones in the near future as 4K content becomes mainstream.

Would you be interested in buying a device with a 700 ppi screen in two to three years' time? Sound off in the comments below.

LG demoing a 6-inch QHD panel next week, 700 ppi displays coming soon


Yes. But only because I want to read the comments from people who swear they can see individual pixels.

Also, I want a 4k screen on a phone because there's no point in being able to film in 4k if you can't view it in 4k. The UHD TVs are just too expensive

The only way something on a screen isn't "sharp" is if you can see the pixels. Please lookup what "aliasing" means and why you end up with "unsharp" text and such, when the UI is rendered onto the screens pixel grid.

Don't worry, according to the liberal scientists we'll evolve! Pretty soon we'll be complaining about how huge the pixels on our 8k displays are and how we need 16k or 32k displays. Science says so.

Lol "liberal" scientists - as if science is based on politics. You may confused it w Art - "in the eye of beholder". Numbers Run as Independent candidates , that's maybe why they are not as popular, but once accepted, they are unifying , not polarizing communities :))

If you truly know anything about science, then you know it's very often subjective and political, like man made global warming and evolution, etc

They can be made polticial, but they most certainly are not subjective. There is an objective truth. And in the case of both evolution and global warming, a vast majority of scientists believe in it. Its no longer a debate among those educated in the field... ( Global warming is also a debate in few countries outside of the United States. Both the British Conservative party, and the Canadian oil-sand-loving Conservative party acknowledge Global Warming is man made and happening. Now they might not be willing to do much about it, but they acknowledge it, and pretend they are doing something.)

They say we can't notice the difference, but I'm not so sure that people wouldn't notice anything after switching back to 1080p from QHD...

Maybe you can if you squint your eyes but the difference will not be meaningful.

I have to say I also didn't notice as much of a difference as I expected going from Galaxy S3 to HTC One M7 (though part of that may have to do with AMOLED vs LCD). Going back, on the other hand, is a completely different story. Now the GS3 screen looks terrible by comparison.

I 100% agree with you. Note 2 to Note 3 I didn't see much of a difference. The Note 3 was just brighter. I even put the same images on the screens (home page of the Play Store).

Absolutely not. Unless, I start working as a graphic designer or photographer in need to zoom in and edit. talking about 10in +
On s 5 in device for any content 700ppi is just a waste of materials, energy and time. the only benefit would be if one needs to zoom in on some DSLR photo and look for the smallest detail. Other than that, from 10-15 in distance no video or image is gonna look sharper to your eye.
I also don't know the extra amount of light needed to push through dense panel like that to keep it bright enough - energy consumption.

Nope. After FHD screens, ppi and pixel density are just becoming unnecessary. It's better than retina, but 538 is probably where manufacturers should stop.

While going past 1080p on a cell phone screen runs into some seriously diminishing returns, there are things that will benefit from mass produced, very high ppi screens. VR googles, like the Occulus Rift, for example.

Nope. Until I have close to no choice on the matter, I intend to avoid anything above 1080p. I was fine with 720 on my Note II. My HTC One is fantastic, but I can only tell the difference between LCD and AMOLED. Not so much on the ppi.

There's a big difference between amoled and lcd. amoled allows for deeper black levels and the ability to only light up pixels that are being used on a display. For instance if you were viewing a black page with white text only the white text would be lit up while the pixels on the black areas wouldn't be lit. The trade off how ever is that lcd screens have better visibility in direct sunlight.

Just for clarification, I was saying that the difference between AMOLED and LCD is like night and day compared to the difference in pixel density which is much harder to contrast. I actually chose the HTC One partially because of the visibility in sunlight.

Neither 1 of you have used the galaxy s5 or the galaxy note 3 then because direct sunlight is no longer an issue with either of those amoled panels...I came from a note 2 to a note 3 and that was my biggest concern because direct sunlight visibility sacked on the note 2...they have fixed that problem on amoled.

Always with the direct accusations. I will admit that I have never used either of those phones in direct sunlight, however I have played with both. I will stick by my comment saying that there is a noticeable contrast. I wasn't trying to bash the technology, merely say that they are different and that my preference currently lies with the LCD display of the One M8.

LCD does provide better visibility in direct sunlight, but I really like the way AMOLED looks. To each their own. It's a great thing that Android and the OEM's give us choice :)

The only downside is that auto brightness on Note 3 is not high enough for direct sunlight, so I gotta max it up manually. Under that condition LCDs would drain the battery less, because they don't need all that power. They tend to last longer too (in brightness terms - burn in pixels).

Check out Lux. You adjust how the auto brightness works. For me, I'm pretty photosensitive, and it will even let you go "sub-zero" with the adjustment. The ability to set the screen brightness to -18% in a dark room is a life (and eye ball) saver for me.


It's totally work the couple of dollars it costs, but they've got a free version you can try out too.

I would prefer to have better battery life, faster processor, better camera, or basically anything else instead of more ppi's on the phone's screen... 400-500 ppi are enough, even if you put your eye at a few inches from the screen.

You are absolutely right. Why can't these companies advance the industries snail pace when it comes to battery life? If I can't enjoy all these smartphone features for an extended period of time during the day(s), what's the point? There is never diminishing returns when it comes to more battery life.

Why not both?

Battieries have been around for centuries. The first electric car was built in the early 1900s. In all that time battery tech has not improved all that much (in an overall way) so maybe the answer does not just lie in the battery itself, but in how it is used.

We are getting faster, more efficient CPUS, GPUS and everything else. Why is it that the screen itself cannot project more pixels while using less battery? Wouldn't that extend the daily battery life just as well as squeezing in another 500 MaH to the battery?

Of course not, all we see is MOAR SPECS and then decide right fomr those numbers whether or not it is a good thing (SD 805 or the phone is a loser) or a bad thing (800PPI is the debil)....

There has to be balance.

Yeah, maybe it's more power efficient, but I don't know...

Everything comes at a price; if it's better in some aspect, it's probably worse in another one. So either it consumes more battery, has less brightness/color quality, or costs more to produce (which will reflect in the price we pay for it).

Anyway, that's one of the reasons of why I'm looking forward to Project Ara... The way I see it, everyone can be happy: people who like to min-max cost/benefit and resources (like me), or people who like absurd numbers and don't worry about about its drawbacks.

They got competition on android and the only reason they "go bigger, better etc is duo to sales. Compare it for example with iphone and blackberry. I would love to see 1080p screens there, but the processors etc is not really needed. Only on android and soon ob windows mobile you will these things.

Ok. I am really tired of the crowd that says "you can't tell the difference in screens". seriously. I can tell you, from first hand experience, that it is incredibly noticeable when you jump from something like a Galaxy Note 8 screen, to a Galaxy tab pro 8.4 screen. Now, Sure, i didn't notice until about 3 or 4 days later...when i upgraded, BUT THERE IS A HUGE DIFFERENCE IN VISIBILITY once you go back to the note 8.0 screen. it seems literally blurry. I am a huge tech geek and have all the latest phones etc. I currently have the G2, and when screens jumped from 720 to 1080, people were bitching it wasn't needed and there was no visible difference. Get a life people. Take a Galaxy S3, and compare it to your G2 or S5. It's night and day visibility. Can you live without it? sure, but don't knock it until you try it. It is nicer to have cleaner text. Apple built a business on it. So tired of the Hi Res screen haters! Don't buy it if you don't want it. I look forward the G3...and if history plays a role, the G3 will be a noticeable difference to my eyes, contrary to what people say the eyeball can actually pick up. and it will be a bonus when i project it to my 55"tv. (I am 42 years old, with good eyes and no glasses). I wouldn't trade the Tab pro 8.4 screen res and go back to the note 8.0 for anything. it's now blurry. and I wouldn't trade my 1080p phone screen back for a 720p. text is much clearer.

You say "Apple built a business on it" but their current "Retina" display is only 326ppi.

I'm still pretty skeptical that the difference will be worth the trade off in performance and battery life. I didn't see a substantial difference between 720 and 1080, personally. I suspect most people who claim to see a difference, couldn't tell a 1080 screen from a 2K screen if they were held side by side and the person had to pick one.

As for your "first hand experience" you're comparing something with 189ppi (Note 8) to something with 359ppi (Tab 8.4 Pro) so I have no doubt you could see that difference. I don't believe the same would be true going from 359ppi to 600ppi.

If they add a stylus with S-Pen like functionality I will be right there with you. I am very surprised that no one has looked at the success of the Note series of phones and emulated it. It is not just about the bigger screen, it is the added functionality.

Agreed. I would have trouble moving to a device without the stylus, now that I've been using a Note for a couple of years. Yes, it's more convenient to use your finger most of the time, but when you need that extra precision it's a godsend. I don't carry a pad and paper into meetings at work anymore. I just scribble my meeting notes onto my phone, using Papyrus. And, no, it's not even *remotely* the same using a capacitive stylus.

I'd say anything over the g3's ppi is pushing the limit. I can see pixels on my g2's screen if I squinted extremely hard when its brightness was very low. But the screen to me was still very sharp.

For me 1080p is just fine for phones. I only want 4k on a device with more than 200mm — probably more than 250mm (~9" yea?)

For me 720p on phones, 1080p on small tablets and 2k on 10 inch tablets is enough, no need for that many pixels

I won't say it's not worthy until I see one myself, but will I have to carry a backpack-style battery?
Companies should focus on battery technology, imo...
