Samsung and its frequent partner Nouvoyance said on Thursday they would show an ultra-sharp LCD optimized for tablets. The 10.1-inch, PenTile RGBW-based (red, green, blue, white) screen reaches an unprecedented resolution of 2560x1600. At 300 pixels per inch, the panel's sharpness is double the 1280x800 on most early Android 3 tablets and 2.25 times sharper than the 132PPI of an iPad 2 screen.
