Japan Display teases super crisp 432 ppi 7-inch panel for next year

by: Bogdan PetrovanOctober 18, 2013


Japan Display Inc (JDI), one of the world’s top manufacturers of LCD displays, announced today its Innovation Vehicles for 2013, demonstrating new technologies that will make it into consumer products in 2014 and beyond.

The most interesting new prototype from Japan Display is a 7-inch tablet display that shatters current pixel density records. The 1,600 x 2,560 (Wide-QXGA) resolution of the new 7-inch LCD TFT panel translates to an amazing pixel density of 432 ppi.

Thanks to JDI’s WhiteMagic technology, the panel consumes 60 percent less power than conventional RGB displays, offering comparable brightness. The 1.17mm thick panel integrates touch and accepts stylus input, thanks to the Pixel Eyes technology.

Currently, the highest density tablet displays on the market reach 323ppi (Nexus 7 2013, Kindle Fire HDX). Another notable contender is the 10.1-inch Transformer Pad TF701T from Asus, which clocks in 299ppi.

Upcoming high-density displays from JDI and other manufactuers will put tablets on par with current generation smartphones when it comes to pixel density. However, 2560 x 1440 smartphones are already in the pipeline. Back in August, LG Display teased a 5.5-inch panel that reaches an impressive 538 ppi, and Chinese manufacturer Vivo looks to be the first phone maker to use it in a product.

    Why ?
    Who needs it ?
    It’s getting ridiculous, like MegaPixels on digital cameras.

    • Luka Mlinar

      At one point to high resolution starts to look bad. That’s why the moto X is 720P

      • Cristi

        The normal human eye do not see more than 250-300 dpi at 10 inches. So why bother.

        • Horacio Chagas

          because we can

          • Cristi

            Why not developing better battery ?

          • VL

            Because we can’t :D

      • MasterMuffin

        no, Moto X is 720p because of
        a) it would be much slower if it was Full HD
        b) nobody can make such a small Full HD AMOLED display

        • Ivan Myring

          The HTC one has a 4.7 inch display as well, but 1080p

          • MasterMuffin

            But it’s LCD, not AMOLED

          • Roberto Mezquia Jr

            so you think that because nobody has one, that its impossible? the MotoX is that size b/c it works best for what they were aiming to do… nothing to do with them not being able to make it 1080p… the difference in quality is negligible at best… but you are correct, i kinda skipped over that word AMOLED lol

          • Sameer

            Dude… I can really understand how frustrated u must be! !!!! HTC one is LCD not amoled!!!!!!!

        • Roberto Mezquia Jr

          So you completely forgot about the HTC ONE with a 4.7″ full 1080p screen?

          • MasterMuffin

            If people only read my comment… AMOLED >:|

        • Luka Mlinar

          It can be done. Just not well.

          • MasterMuffin

            What do you mean by that? One subpixel? :D

        • Luqmaan Mathee

          Samsung makes full HD AMOLED displays.

          • MasterMuffin

            Arrgh my brain hurts. I quit. I say this one last time and after that, I’ll ignore every single one of the replies I (may) get: AMOLED

          • Luqmaan Mathee

            Oh sorry. I didn’t see small. Forgive me bro.

  • Ivan Myring

    What about the kindle fire HDX 8.9? this resolution at 8.9 inches. Like 350ppi

    • Roberto Mezquia Jr

      HDX 8.9 is 339ppi… And its not out for sale yet… So this article speaks the truth… Also, its a Kindle, have you ever tried using a Kindle lately? those things suck unless you root and install a custom ROM on them…

  • wat

    This is amazing

  • Roberto Tomás

    “1.17mm thick panel” — that kind of thickness almost always avails itself to bezelless designs, I hope we see bezelless 7″ tablets next year

    • mustbepbs

      How would you hold it?

      • Roberto Tomás

        I take it you haven’t seen the LG G Pad 8.3

      • RanRu

        It’ll have suction cups on the back. :D

  • Sunny

    thats innovation that is useful.

  • RanRu

    Who’s going to hold a tablet three inches from their face all the time? Because that’s what it would take to notice it.
    I also take it that’s 60% less power than a comparable LCD display, not a 7″ 1080p LCD.
    I wish OEMs would shift focus from these ppi wars to things that mattered, like color gamuts wide range brightness.

    • Cao Meo

      you are wrong, sameting with 1080p for phones and people love it,

      you may not see individual pixels and with lower res but you’ll notice the difference in sharpness.

      • RanRu

        I do believe that 1080p phones are noticeably sharper when you focus on it, but not to the extent that you’d notice a difference on a day-to-day casual basis.
        The main problem here is that you hold a tablet 2x-3x farther from your eyes than you do a phone, which means that you only need 1/3 to 1/2 the pixel density to see the same amount of detail. These new displays are impressive on a technical level, but I believe there’s a much more appreciable difference to be seen from novel technologies (such as the white pixel tech) rather than simply stuffing more pixels into a display.

        And that’s my 2¢

    Sony Xperia Tablet Z1 ?
