WWDC 2010: iPhone 4 Has “Retina Display” With 4X Pixel Density Over iPhone 3GS
The second big thing about the iPhone 4, according to Jobs, is the revolutionary new display.
They’re calling it the retina display, and it quadruples, as reported, the pixel density of the last iPhone. You now get an industry leading 326 pixels per inch in the iPhone 4. It’s a marked improvement on the display in the 3GS in both brightness and clarity.
“There has never been a display like this on a phone,” says Jobs. “People haven’t even dreamt of a display like this. It turns out there’s a limit around 300px per inch that the human eye can’t differentiate between the pixels — text looks like you’ve seen it in a fine printed book, unlike you’ve ever seen on an electronic display before.”
“Once you use a Retina Display,” Jobs confidently brags,”you just can’t go back.”
