There's a report from Korea suggesting that Samsung managed to reach 350 ppi on a OLED display using FMM (Fine Metal Mask).
Up until now Samsung focused on LITI to reach such high resolutions, but if this is true then Samsung can quickly apply this production process to their current AMOLED tabs.
This is good news for the next generation of Galaxy S smartphones. We do not think that Samsung will bring this to the Galaxy Note II because it too close to the release.
Hopefully we'll soon hear more of this achievement if it's true. One of the major advantages of current LCDs over OLED panels is the higher possible density (Apple's Retina display for example reaches 326 ppi), so this may be a huge boost for OLEDs.
Some other thing we know is that the first TIZEN developer device use a Super AMOLED HD PLUS screen. Which is ultimate sharp.
See the pictures comparing with the Galaxy Tab 7.7.
It's possible that doesn't look that sharp, but that is because of the camera, but it is really sharp. (believe us)
PPI of other devices.
Galaxy Tab 7.7 196 ppi pixel density
Galaxy S 233 ppi pixel density
Galaxy S II 217 ppi pixel density
Galaxy Note 285 ppi pixel density
Galaxy S III 306 ppi pixel density
iPhone 4S 330 ppi pixel density
