“Steve Jobs dazzled the crowd Monday with one of the iPhone 4’s snazziest features: an ultra-high-resolution display that puts to shame any other cell phone on the market,” Christopher Null reports for Yahoo! News.
“With a resolution of 960 x 640 pixels, the iPhone 4 crams more graphical ability into a 3.5-inch diagonal space than any other gizmo on earth,” Null reports. “With a density of 326 pixels per inch, Jobs claims it’s better than the human eye can even detect at a standard viewing distance. In other words, if Jobs is correct, you’ll have to hold the phone right up to your face to see the iPhone 4’s pixels at all.”
“iPhone 4 has more than just raw pixels. Apple is also touting its optical lamination process, which basically adheres the glass directly on top of the LCD so there’s no gap between the two,” Null reports. “As Displayblog explains, this ‘improves sharpness and clarity of the display by eliminating light refraction, which is caused by the small distance between the glass surface and the LCD that exists on pre-4 iPhones.'”
“Finally there’s IPS [also used in the iPad’s display], “Null reports. “It works by arranging the crystal structure within the LCD such that the crystals are parallel with the glass screen above. Traditional LCD screens have crystals at odd angles, which decreases brightness and makes viewing at odd angles difficult, but IPS corrects that problem by creating order from the chaos.”
