Samsung working on a 4K '800ppi' phone screen, and 7th-gen AMOLED displays
This alleged Note 8 schematic may actually depict a 4K display
How about that "800ppi high-resolution OLED," though? This kind of pixel density isn't for TV screens or tablets, but rather smaller devices, like phones. A 5.5" display with 3840x2160 Ultra HD "4K" resolution would have exactly 801ppi pixel density, for instance, and it's not the first time Samsung is rumored to be perfecting such a 4K screen. Samsung was said to equip the S8 with those, but it went the route of Infinity Display, and we can't say that we are disappointed with the result.
The Note 8 is rumored to arrive with a 4K panel, but if it is indeed a 6.4" one, as speculated, and Samsung wants to keep its new 18.5:9 ratio, the phablet might score a 4428 x 2160 resolution, with the on-screen buttons strip occupying a hundred pixels or so at the bottom. That would return "only" 770ppi, though, not 800, but it's in the ballpark, so VR aficionados might be inclined to give it a pass.
After all, so far only Sony has phones with 4K displays in its "Premium" line, so if Samsung pulls this off, it would be a cause for significant bragging rights, and battery life nightmares.
