Samsung develops AMOLED display with better resolution than Apple

Electronista reports that Samsung has managed to increase the resolution of its AMOLED displays to 350 pixels per inch, higher than the density of Apple's Retina Displays (264 to 326ppi), without having to make major changes in its manufacturing process. However, Samsung has achieved these improvements only in its labs so far, so it's not clear how long it will take for them to reach production.
