Japan Display Working on 4k Tablet Screen

By - Source: Tom's Hardware US | B 30 comments

Now that even cell phones have the graphical oomph to render things in gorgeous 1080p, the 4k leap will be the next big milestone. Tom’s has spoken quite about it before, particularly what it’ll take to render all the pretty modern games with almost 8 million pixels, and while it’s a hefty drain on system resources even for a desktop, the tripartite Japan Display partnership is already trying to cram all that detail into a tablet.

Engadget reports that the coalition between Sony, Toshiba and Hitachi have announced that they have a fully functional 12.1-nch 4k TFT package. It’s a stunning achievement, and while one might think it’d be a huge drain on battery power and need a killer set of hardware to push all that additional detail, the Japan Display group maintains the module is power-efficient and fairly thin, given the real complexity of it.

The full report is linked here, and it’s not too hard to make sense of with the help of Google. Some other things to note, the viewing angle and contrast ration are a fair bit lower than what is standard these days, especially for portable electronics, sitting at 160 degrees and 1000:1 respectively. Curiously, the screen brightness is also remarkably high at 500 nits. Crunching the numbers for the power draw of the panel itself and looking at standard battery sizes results in something in the neighborhood of twelve hours, though that’s only for the display.

If this comes to market within the next year, I’d be shocked, but it’s definitely something that’s fun to think about as we toss around bigger and bigger numbers and look to up the prettiness factor on the electronics we use every day.

    Oh god no :( 
    This PPI war need to stop and instead focus on color gamut,contrast, response time... etc
    and give us GPUs that can fully handle today's 1080p/1600p mobile and tablet displays instead of the measly ~100gflops gpus available in devices right now.

    I'd like to have one of these...

    You will have 4k in tablets and phones before you can afford one for your desktop...
    Nice...
    But good to see that at least tablets are soon ready to 4K time, lets see when the CPU/GPU for the tablets can for the same... in two years?

    ^ Agreed. Unless you sit 3 feet from your screen, 1080P is good enough. I want epic contrast ratios that aren't dynamic and so many colours I barf rainbows when playing games please :D

    In 10-15 years, people will joke about how people from the 2000's and 2010's thought 720p and 1080p was "good enough"

    A GTX Titan struggles to provide consistent high FPS on that resolution. Surely this will be a more abysmal experience gaming on than the Nexus 10, even if they use a next gen Snapdragon.

    It's not like you're gonna be playing Crysis 3 or Metro on a tablet anytime soon. To power this, for basic usage, even Intel HD graphics would be good enough.

    I imagine they will joke about how companies wasted their time on screen improvements that were imperceivable to the human eye, but thats just me

    You've probably never used a 4K monitor...

    Trust me, you notice. Especially going back to a 27" 1080p screen.

    yes on a 27" display i am sure i would notice, however on a 12.1" screen as the article discusses....i have doubts

    4K res is kinds useless on a 12" screen, yes.

    out of curiosity does anyone know what the PPI on a screen like that would be, I tried working it out but my answer was outlandish

    ~365 ppi.

    Huh, there you go, I always thought PPI was PPI^2, no wonder my answer seemed way to big. Well I have learnt something today

    With a very keen eye you might be able to notice a small difference with a 4k screen on a 27" monitor over 2k. However, you could get those same results with a 3000 or even a 2500 pixle wide display. At comfortable viewing distances and realistic screen sizes, 2k is pushing the limits for what the human eye can perceive.

    The only reason 4k receives so much hype is because that is what manufactures want. Higher resolution is easy to develope and even easier to market. The consumer would be better served with advancements in color quality than increased resolution.

    Don't perpetuate the hype.

    If they can build 4k 12 inch panels, where the hell are the 24 inch panels, it should be FAR easier to make desktop monitors with that resolution then tiny screens.

    In a tablet 4k is largely a waste, but for a 24" desktop monitor it would make a difference.

    Unless.....you like to hold your tablet 1 foot from your face---which no one does---you would never notice the difference between 2k and 4k.

    4K is absolutely unnecessary for a tablet. But, like the term 'HD", it sells itself to unsuspecting customers

    4K may be worth looking into for 17 - 18" gaming laptops....in a couple years when the hardware is good enough to actually run a game at that resolution (note I say run, not max out) , and when 4K content is widely available

    What most of you are skipping over here is that while 4k isn't necessary for a visual standpoint, you reap massive rewards in running native format vs having to always use the processor to scale EVERYTHING. The extra power needed for the screen will ALWAYS be less then the amount of power to re-process a 4k image down to a lower resolution. Not to mention that any type of scaling producing visual artifacts as a pixel can only ever be one color as one time.

    Squeeze it down a few inches, throw it in the Oculus Rift.
