Sharp readying 600 PPI displays for smartphones and tablets

May 6, 2014

    Japanese electronics giant, Sharp, is prepping its manufacturing lines for mass production of the company’s next line-up of mobile displays, where it will be producing the industry’s highest resolution displays for tablets and smartphones.

    The display manufacturer is currently sitting in second place behind rival Japan Display. However, its new displays will see Sharp claim the mobile display crown, thanks to its cutting edge 600 pixel density per inch panels. Sharp will start off producing 5.5 inch LCD panels for smartphones, followed up with 7 to 9 inch LCD versions for tablets. Production is expected to start as early as next spring, so we won’t be seeing any of these displays this year.

    Sharp is also touting that its new panels pack the clarity to enable viewing of 4K content on small displays. However, it’s a little tricky to figure out which displays will be featuring the high pixel density and 4K resolution.  My calculations put the display size at around 7.3 inches, for a resolution of 3840 × 2160 and PPI of 600. Therefore, Sharp’s first batch of 5.5 inch smartphone displays certainly won’t be 4K capable, that would result in a PPI around 800, but its larger tablet displays will most likely match the 4K criteria.

    QHD displays are currently leading the smartphone market with about 540 pixels per inch.

    That’s not all the company has planned for mobile displays. Sharp is also keen to push its IGZO panel technology into new mid-resolution devices, which could mean more smartphones and perhaps even a move into the wearables market. IGZO is Sharp’s more energy efficient LCD technology, but the design is currently limited to panels with only around 300 PPI.

    With the global market for sub-9-inch panels for smartphones and tablets expected grow 70% from 2013 to reach $56.4 billion in 2018, Sharp’s leading technology puts the company in a strong position for the coming years. But perhaps the more important point to consider is – do you want devices with even higher resolution displays?

      We needz dis not. Seriously, battery efficiency, thickness, durability etc. are the things they should focus in, not making displays with over 600PPI…

      • Rick jaan

        i agree … 1080 is enough for smart phones n phablets, while QHD 2560×1440 is enough for tablets 7- 10.1 ..
        battery is big problem now a days. no cellphone last more than 2 -3 days

        • Rooney-

          OH god !!! You get 2-3 days of battery backup??? May i know what phone and the battery capacity ?

          • MasterMuffin

            “No cellphone last for more than 2-3 days” doesn’t mean its his usual battery life :)

      • Shark Bait

        Totally! Where the hells all this grephene??? I’ve never seen any ? I think its all a conspiracy…

        Thickness?? New technology for batteries and reduce upper and lower bezel a bit more than LG’s ISAI and that’s that, smartphones are done.

        • MasterMuffin

          I was talking about screen thickness that would allow bigger internal parts like battery etc :)

        • kirakira

          before referring to lg isai as the bezel minimizing leader, you have to realize that sharp already released a number of phones with a similar near-zero bezel design, albeit not curvy, many months before.

      We just need one simple thing….. a battery life lke a nokia

      • Shubham Singh

        present nokia or the old nokia

        • Mohd Danial

          Old nokia when the batteries could last fo weeks

    • Shark Bait

      More mAh plz , not DPI

    • Gaurav Arora

      I’m pretty sure Sharp showcased high pixel dense IGZO displays? iPad Air has an IGZO screen!

    • Andrew White

      Difficult to ascertain what technology Sharp will employ to arrive at this magical 600ppi mark, but if used on future Android devices it means there will definitely be a ‘wow’ factor in terms of public perception, with a net affect of taking sales away from Apple.
      As far as battery usage is concerned there may not any discernable difference with the increase in ppi and or resolution. It can only be speculation at this stage.
      Rapid charging will be common place realistically by the time this new screen tech is brought to market, therefore battery drain won’t be an issue.
      Smartphone tech is the shinning light in consumer electronics, the evolutionary process has been rapid and will continue to be so.
      I’m luvin it!

      • Mohd Danial

        If u constantly charging to use the epic display.. it isnt eco friendly.. if u got a strong battery
        . U will less likely find a place to charge and not worry abt not be able to remain uncontactable thereby save time

    • Piotr Rogulski

      If they can make such screens, they must be able to do powerful batteries for phones

      • thartist

        Totally the same thing!

        • Piotr Rogulski

          Well, because what can we do, when there isn’t enough energy to power all the pixels?

    • Ruz

      Am not impressed with 4K display.. I saw nearby Samsung 4k set and i wasnt impressed.. My 1080p set looked much better

    • uihiu

      That’s about a high quality magazine(dpi). Enough!

    • John Zakaria

      But what is the difference between dpi and ppi

      • spade

        Dot/Pixel Per Inch

      • Woe, Is [S]unjay

        Isn’t DPI for printers?

        • John Zakaria

          Now it is for everything.
          Or how much is the density of colors which are in each inch

    • Sal

      Oh please stop. We are pretty much at the point where you don’t need to increase the PPI. 1080 is enough. Please find ways to increase battery life cause that is still a problem on all smartphones and tablets. The 600 PPI could work if only it is equipped with a stronger battery.

      Haha when companies run out of innovative ideas, they do these stupid pissing contests for something the consumers never complain about.
