And yet another absolutely not needed development. From 30 cm on a 6" screen you see FullHD- do your math. I did. No one can see above fullHD from 30cm. So this display is a waste of R&D effort and waste of money. 2560x1600 is needed above 7" okey- just to make it astonishing - but instead of resolution display manufacturers should concentrate on Energy consumption and color gammut. Now that is nowhere mentioned - such a shame.

    The eyes limit is NOT on the absolute ppi resolution, but relative to the viewing distance.

      734 ppi = battery drainer!
      this should have at least 4500 mah of battery power or more on every single phone...

            I've been following the development of IGZO tech. 2 years ago (circa 2012), I've read an article about the benefits of IGZO. IGZO TFT is said to be thinner and more energy-efficient than mainstream OLEDs (Super AMOLED and AMOLED included), mainstream IPS panels, and mainstream regular TFTs. Even Sharp's executive VP, Kozo Takahashi, said at a previous CES that IGZO is the "key to the future of next-generation organic LED (OLED) displays."

            So when it comes to battery-saving demands on future 4K UHD or 8K UHD/FUHD mobile phones, I'd rather have IGZO as display panel than common OLEDs, IPS panels, or TFTs regardless of how large (or minute) the screen size it comes with

            IGZO for me is old tech. Sharp already introduced its first phone and 7" tablet with FHD (1080p) IGZO screens but were exclusive to NTT DoCoMo

              Completely useless resolution. Human eyes can barely see the difference between 720p and 1080p if at all, there is no point in this high resolution whatsoever apart from self marketing.

                the good news is that we will have high end small phone. the bad news is that the resolution is useless and will only draw more power. I have a 27" monitor with that resolution and it is perfect. The distance from eyes to monitor is 70cm. The distance to phone is ~35cm. The screen will have to be 13.5" to use that resolution

                      Dododo, 13 Nov 2014Of course, only people with really, really Sharp eyes will ... moreIt is a matter of the viewing distance!

                      Try downloading this PNG and do the one minute vision-test yourself on any phone/phablet/tablet/pc, I'm sure you will be surprised how fine details you can see - I sure was! I'm over 50 and with not too good vision, and still get 1/7000 of the viewing distance, many have reported finer than 1/11000...
