Full HD who? 2560 x 1440 Quad HD LCDs for smartphones announced by LG Display

August 20, 2013

    LG Quad HD Display

    LG Display has announced a monster of a smartphone display with a resolution of 2560 x 1440 and a pixel per inch (PPI) density of 538 on a 5.5-inch panel – a world’s first – which we could see in the future on Android devices.

    In addition to offering Quad HD resolution – or four times more pixels than an 1280 x 720 HD panel of the same size – this new AH-IPS LCD display is also “the world’s slimmest and narrowest panel” beating the company’s 5.2-inch display that was just recently announced (and which is found on the LG G2).

    According to the press release, the Quad HD display is 1.21mm thin and has a 1.2mm bezel.

    Furthermore, the display also offers a brightness of 430nit, made possible by the Low Temperature Poly-Silicon (LTPS) substrate.

    The company did not reveal what upcoming smartphones will use such a display, but did say that research firm DisplaySearch expects LTPS-based smartphone display shipments to reach 765 million next year, “as displays with larger screens, higher resolution, and less power consumption prove key to competitiveness in the premium model segment.”

    LG certainly appears ready for the next phase of the display battle when it comes to mobile devices. But is it really worth moving above Full HD displays in smartphones?

    LG Display Develops World’s First Quad HD LCD Panel for Smartphones
    New panel will deliver optimal viewing experience on larger smartphone displays

    Seoul, Korea (August 21, 2013) – LG Display [NYSE: LPL, KRX: 034220], a leading innovator of display technologies, announced today that it has developed the world’s first Quad HD AH-IPS LCD panel for smartphones. At 2560X1440 with 538ppi, the new 5.5-inch Quad HD panel is the highest resolution and ppi (pixel per inch) mobile panel to date, and provides a glimpse at what’s next after current Full HD smartphone panels, critical given the growing trend towards larger displays.

    “LG Display, which pioneered the high resolution mobile market with introduction of the world’s first Full HD smartphone panel in 2012, again opens new possibilities with the successful application of QHD technology,” said Dr. Byeong-koo Kim, Vice President and Head of LG Display’s IT and Mobile Development Group. “With this breakthrough, LG Display will continue to raise new standards for mobile resolution and lead the mobile display market.”

    LG Display’s Quad HD panel for smartphones realizes clearer images with 4 times more pixels than HD at 1,280X720, thereby reproducing more delicate colors as well as improving contrast and vividness when compared to current mobile displays. This advancement will enable consumers to fully enjoy more life-like and crisp images, and even Blu-ray equivalent video, on their smartphones. The panel also features the highest ppi among current mobile device displays.

    In addition, the new Quad HD panel will enable users to enjoy a full view of PC-version web pages at a single glance without image distortion; a contrast to current Full HD displays which only realize 3/4th of a full screen. Also, even when enlarging the screen, users will be able to enjoy undistorted and sharper text.

    Only 1.21mm thin with a 1.2mm bezel measured in LCD modules (LCM), LG Display’s new Quad HD panel is both the world’s slimmest and narrowest panel, with 12% reduced thickness compared to the company’s 5.2-inch Full HD panel released last month. Based on Low Temperature Poly-Silicon (LTPS) substrate, the panel also realizes superior brightness of 430nit with improved transmittance and larger aperture opening size.

    LTPS-based smartphone displays are expected to record 765 million units in shipments next year according to research firm DisplaySearch, as displays with larger screens, higher resolution, and less power consumption prove key to competitiveness in the premium model segment.

      and then they’ll have 5mp Camera and a 3mp front facing… lol

      • APai

        honestly, I’d take 6mp/ 3mp if the quality matched the output from Nokia 808

        • Vardan Nazaretyan

          That means, they need to have 41MP front-camera to oversample the images and use the whole lot of pixels to improve the image/video quality.

          • APai

            I don’t know, that’s not the only way to do it. the pelican imaging system is there. then there are other interesting flat lens technology out there. a large flat lens with a large sensor on the phone can be the answer. someday, we will see it.

      • TY

        While 2560×1440 is only 3.7MP…

      • Vardan Nazaretyan

        Some device made by OPPO has already a 5MP camera on the front. It’s called Oppo Ulike 2S.

      True Story!

    • Joshua

      RIP 1080p, your out dated buddy ;)

      • SkylaC90

        that is because exactly zero apps take advantage of Quad Core Processors, Hell Android itself doesn’t even take advantage of it even though the OS is fully capable of doing so, so they really aren’t needed as of yet.

        • smellysnatch

          Exactly zero? Geekbench, antutu and I’m sure emulators and graphic heavy games do too

          • Vardan Nazaretyan

            Benchmarks do take advantage, but Games not, games take advantage of the GPU.
            I can’t tell whether emulators are using CPU or GPU to work, but I’ve read somewhere, that they use CPU, so yes, if it’s true, then Emulators will take advantage of the CPU.

        • lil bit

          Ok sure, if it makes you feel better then why not.

        • Joshua

          Exactly what I was trying to say.

      • bill mesa

        while in the meantime, apple no longer pursue screen density.

        apple currently focused on making 128GB storage on their iphone, while android world still struggle with 32/64 GB storage.

        I’m sure after this phone manufacturer will no longer pursue screen resolution and start to make large internal storage.. ;)

        .

        ps: nope I don’t use apple product, I use optimus one & one x.

        • Cole Raney

          IPhones only go up to 64 GB the iPad has 128 GB of storage

        • Wildfire

          Have you ever heard of SD cards ?
          64GB iPhone 5 costs the hell, can’t imagine how will be the 128GB version. I doubt i’ll even exist.
          No ,storage isn’t the most important. I might say companies should work on battery life more. Thing that Apple won’t be the best at

      • Leandro Brandão

        i can see now the difference between my dual core galaxy nexus and my new quad core nexus 4. but i still prefer 720p screens on 5 inch phone, unless battery technology changes a lot.

        • Joshua

          I was talking more about apps taking advantage over the more cores, not as much as the OS

      • abazigal

        Innovation should be making our mobile computing experience better, not simply be another meaningless spec in the box. Where are the denser batteries and that long-rumoured IGZO screen?

        Are people really willing to make do with 1/2 the normal battery life just to boast of having a super-high-res screen?

        • MasterMuffin

          There are already devices with IGZO screen

    • Robert Crosby

      LG always first supposedly

      • G2forme

        first and the best!

        • ibbi

          lol

    • http://petercast.net Peterson Silva

      It doesn’t really matter though when you have an android skin as ugly as LG’s…

      • mrjayviper

        I’m sure you know LG sells displays to other makers.

        • http://petercast.net Peterson Silva

          Of course I know, I was just noticing the irony in the fact that such a beautiful screen came from one of the worst UI offenders :)

    • Cao Meo

      I don’t think people need more sharpness in smartphones, but if Quad HD can offer somethings else like thinness or low power consumption then why not.

    • simpleas

      You know what’d be funny, Samsungs Note 3 using this lol

      • Amine Elouakil

        a Pentile Amoled bro, you won’t this in commercial phone till next year, this is in the prototype phase, now they have to set the production for it, and if there are no issues expect to come in 6months more or less with first phones presented with it in WMC

    • jjordan

      I say as long as power consumption keeps moving in the right direction with these massive pixel count displays than why not…our smartphone are becoming our second screen technology anyways so why not make em better and better and better

      • abazigal

        Diminishing returns. All other things equal, a lower res screen would still result in longer battery life in tandem with battery improvements. I would question just how much of an improvement 500ppi would show compared to 400 or even 300 ppi.

        • Taylor Swift

          Look at Mr. Economics here

          • OMGgary

            I knew you were trouble when you walked in.

        • jjordan

          TI understand what your saying I really do and I also believe that the world of technology is incredibly close to a major break thru in battery tech. I’ve read tons of articles that say what we are going to see sooner rather than later as consumers are quick charge capabilitues. By that I mean when you plug your dead smartphone in it completely charges in a matter of minutes

    • Deo Reyes

      As long as it doesnt eat up my phone’s power, yeah ill buy that.

    • lil bit

      It’s surely worth it for phablets, and also on 5 inch for some of us. I can still see tiny imperfections on full HD 5 inch displays when reading very small text. Yes it’s invisible for the majority, but Average Joe can’t be allowed to decide what’s enough for everybody else, that’s like banning sex to not offend the impotent guys.

      Many of the Full HD haters are people who refuse to realize they need reading glasses anyway, they need to start with themselves, not everybody else. It’s like the famous Dilbert strip where he is in the doctor, Dilbert said “I’m addicted to the internet because it’s more interesting than people. Is there a pill you can give to everyone else to make them more interesting?”.

      Anyway, GPU. This resolution is not so big jump in pixel count from Full HD, since Adreno 320 is already doing a good job at Full HD I believe the 330 can do as well or better with quad HD. No problem there.

      • abazigal

        It’s about 1.8 times the number of pixels of a hd screen, so you would need roughly twice the GPU to power the screen.

        • B3nlok

          Thank You! I wish i could vote you up hundreds of times.

        • NeedName

          If directly observable differences are NOT present then it won’t do well in the market — the device will cost more due to the new tech and people won’t see the benefit for the extra cash.

          But the opposite is also true.

          The good thing is, companies are pushing higher pixel densities, thus we might see overall HD display prices drop. There was a long period when companies stopped pushing dpi. . . until apple came out with their “retina” display. Then the race heated up. . . let’s hope it continues whether or not it ends up in a phone or not.

      • NeedName

        330 can push 4K video at 30fps. . . so, it could handle this screen

    • finseeker

      If I can see this display in direct sunlight I am all for it.

      • BDPSU

        It’s IPS, not OLED – so you should be able to see it.

    • G2forme

      1.21mm thin and has a 1.2mm bezel.

      FANTASTIC!

      LG is the most advanced and the best in Smartphone’s Display!

    • Vardan Nazaretyan

      What’s next?
      4K video recording with phone’s front-facing camera and 8K with back-facing camera?

    • Killian Khoo
    • EvenInTheDarkestHour

      Guess I’m going to have to up my glasses prescription…

    • Ryan Castle

      Someone explain to me why our smartphones should have MORE resolution than TVs.

    • james

      It’s always worth to upgrade.

    • RaptorOO7

      Nice to see innovation, but seriously do we need that resolution on a 5.5″ screen. What’s next 4K screens on smartphones.

    • Roberto Tomás

      I don’t see a reason for this to exist —
      1080p actually has a ton of media attached to it, so people care. (4k eventually will too, but that is forever away.) But 1440p has no real use outside of outdated PCs…

    • Anon

      The things which I think many people forget are A.) How much more time we spend on our mobile devices every day vs. planted in front of the TV (or both simultaneously, at least in my case) & B.) Color gradient values. The ability to accurately represent something even as simple as grey scale is so vastly improved through higher definition displays & deeper pixel density, that I, for one, find the viewing experience much more pleasant on my 1080p device than I did on my 720p one. No argument with any commentator. Merely expressing my personal perspective based on my own experience.
