Japan Display Working on 4k Tablet Screen

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.

    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?

    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.

    ^ 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.
