This 15.6” UHD panel is deliciously wasted

IGZO are the manufacturers of many panels you’ll find in modern laptops and tablets. One display at Computex were some of their latest which they were pitching to OEMs. After being used to seeing 3840×2160 pixels being used to drive large displays, here was a 15.6” display driving the same ultra high resolution. At 10 inches it’s easy to reach pixels per inch numbers in excess of 300, but as the size increases, this number becomes increasingly difficult and expensive to maintain. With this in mind, it’s impressive to see a 15.6” 4K panel with 282ppi.

The display features a 1000:1 contrast ratio and 25ms response time, 24 bit colour depth and is an IPS display which results in great viewing angles. The panel weighs in at just 320grams and draws just 1.62 watts of power. These specs result in a truly stunning display of video, the likes of which an iPad Air couldn’t touch. While good in theory, there is of course a big problem with pixels this high, that is running a desktop.

Desktop operating systems are made to display text and images and our traditional trajectory of increasing the resolutions is generally a good thing. Moving from 1440×900, or even 1920×1080, to 3840×2160 seems to be just one step too far. Readability at this size is terrible. Even with 20/20 vision, the content is too small to be useful, despite being simultaneously impressive this much information can fit on a screen this size.

It’s proof that technology is no longer the barrier to displays and rather that we’ve reached the limits of what makes sense at this sized display. 4K definitely shouldn’t be used in a phone and is best served on larger displays, like that of your living room.

    This is actually a really good thing as it also means that more traditional desktop environments are moving to higher resolution displays, the demand of it is slowly seeping into the largest of the portable devices that we have available. The ball is really in the devs’ court now, as they will absolutely need to, at some point, accommodate for a variety of DPI scales in the more traditional environments as it is with smartphones and tablets, though why that hasn’t been done way sooner is beyond me, since I can’t imagine it’d be that hard to implement a UI utilizing vector elements rather than bitmaps.
