Can't wait for the iPhone 4? Neither could we. Ahead of its official Aussie release, we sourced an iPhone 4 from overseas and gave it the full review treatment
The capacitive, multi-touch screen that Apple debuted with the original iPhone revolutionised the way users interacted with a mobile device. But now that those technologies are readily available on other devices, Apple has had to come up with another way to differentiate the iPhone’s display.
Enter the iPhone 4’s ‘Retina’ display. This isn’t a fancy marketing term – it’s actually the name given to a display with a pixel density that out-resolves the ability of your eye to make out individual pixels. Apple achieved this by giving the iPhone 4 a 960 x 640 pixel resolution – the highest that’s ever been available on a smartphone. Paired with the same 3.5in screen of its predecessor, the iPhone 4 now has a pixel density of 326ppi (pixels per inch), which is almost double that of the iPhone 3GS.
Guess which screen is the iPhone 4?
This doesn’t result in any additional screen space like it would on a PC – instead, everything gets allocated four times as many pixels, making text, icons and graphics incredibly clear and sharp. The resolution boost is mainly an aesthetic difference, although the extra detail means you can read the text on a desktop-formatted webpage without having to zoom in.
Apple has also upgraded the display to an IPS (in plane switching) LCD panel, resulting in a wider viewing angle of 178 degrees and better colour accuracy. While it looks dimmer next to the iPhone 3GS indoors, it’s much more legible in direct sunlight.
