The S III's HD Super AMOLED display measures 4.8 inches (120 mm) on the diagonal, making it Samsung's third largest phone display, only exceeded by the Galaxy Note's 5.3 inches (130 mm) and the Galaxy Note II's 5.55 inches ( 141 mm).[70] With a 1,280×720-pixel (720p) resolution, its pixel per inch ( PPI, a measure of pixel density) is a relatively high 306,[69] which is accommodated by the removal one of the three subpixels—red, green and blue —in each pixel to create a PenTile matrix-display; consequently, it does not share the "Plus" suffix found on the S II's Super AMOLED Plus display.[ 71] The glass used for the display is the damage-resistant Corning Gorilla Glass 2.[61] http://en.wikipedia.org/wiki/Samsung_Galaxy_S_III 小三也有 pentile 啊?
