Qualcomm shows off its 2560 x 1440 577ppi 5.1-inch smartphone display

    Qualcomm is best known for its range of mobile processors, but did you know that the company is also working on its own display technologies as well? Known as Mirasol, Qualcomm’s new displays aim to rival the current crop of OLED and LCD displays with a higher resolution and improved energy efficiency.

    Although these products are still quite far from a release, we have been given our first glimpse at next-gen Mirasol displays in a few proof-of-concepts shown at the SID Display Week in Vancouver.

    Qualcomm demoed some of its smartwatch prototypes, which use a tiny 1.5-inch 223 pixel per inch (ppi) Mirasol display. The display is designed to be highly energy efficient, and should offer around a week’s worth of battery life, which is a great selling point for wearable products.

    The technology giant also showed off the same screen used on the back of a smartphone as a mini display for checking messages and other notifications. Whilst these were just concept devices, the display technology should be heading our way in third-party products at some point in the future.

    More interestingly for us smartphone enthusiasts though, Qualcomm also showed off the same technology used in a 5.1-inch smartphone display. The screen has a mighty resolution of 2560 x 1440, which works out at an impressive 577ppi. Compare that to current top of the line 1920 x 1080 smartphones like the Galaxy S4 and HTC One, which have pixel densities of 441ppi and 469ppi, respectively, and you can see that there are quite a few more pixels packed in, resulting in a much sharper image.

    Again, the display is designed to be more energy efficient than current technologies, offering up to six times the battery life over LCD and OLED screens, which is great news for our strained smartphone batteries.

    If you’d like to see these devices and the Marisol display in the flesh then check out the video below, courtesy of Engadget.

    Whilst none of these products are scheduled to come to market, at least not in the forms shown off in the video, we will probably see similar products based on these designs or using this technology at some point in the future. Sadly though, the impressive looking smartphone display is still a few years away from the production line.

      Ridiculously crisp and at the same time power efficient? WHEN WILL WE GET THIS!? :D

        Dont get excited it will not work in night, or any dark place because it uses reflected light.

        And those colors… Well I got a CRT with better colors.

        PS to AA: Kill that awesomely annoying google + baner.

          :okay:

          And yes please to that request!

      Why would anyone want this? I’m satisfield with a 330 PPI display and a longer battery life… Correct me if I’m wrong but I thought that at 330+ PPI the pixels can’t be seen with just your eyes :/

      I love it already. Been saying for quite a while that 1920×1080 is not the end of the ppi race, i specifically mentioned 2560×1440 as the next step for 5 inchers, and that it should be the minimum for 6in hybrids.

      Those who say 440 ppi is overkill, you should have seen it with our eyes, there are still small imperfections, the max ppi for human eyes is probably well above 600.

        Yes, it’s way over 600. BTW is that a typo: “you should have seen it with OUR eyes” :)
