Lets cut to the chase - Apples version of a Retina Display is basicly a high-resolution screen. The iPhone 4 features an eye watering 960 x 640 pixels, which is four times as many on-screen pixels compared with Apples earlier iPhone models. The iPhones screen size measures 3.5 inches corner to corner, which equates to 326 pixels per inch. In layman's terms, the more pixels you have on a screen of the same size, the better the picture quality. You should see greater detail, clarity and colouring compared with any mobile device released to date.
So, what is a pixel?
If you look closely at any digital display, including your TV or your PC, you should be able to make out individual pixels. A pixel is a small coloured block, used on-screen to build up a larger, viewable picture. A pixel is the basic currency of digital technology. But that doesn't necessarily mean that you want to see the individual pixels! This makes picture appear blocky.
The iPhone 4 deals with those pesky blocks through the use of Retina Display technology. With Retina Display technology, it is almost impossible to distinguish any individual pixels on the iPhone 4's screen. The human eye begins to lose track of pixelation past the 300 pixels per inch mark; hence Apple terming the technology "Retina Display". Even if you hold the iPhone up close to your face, it is unlikely you will see any pixels. They are nearly indistinguishable from each other.
The iPhone 4's retina display technology has to be seen to be believed. The LED backlit screen is simply stunning, with exceptional detail and colour reproduction. It's the best screen seen on a phone to date, and this is no exaggeration.
Conclusion
The Apple iPhone 4 has the largest screen resolution of any mobile device to date. Retina Display technology makes the iPhone 4 ideal for taking and viewing pictures and video, with superb on-screen clarity, colour, depth and sharpness. If you are looking for the ultimate in mobile display then you should definitely consider the iPhone 4 and its Retina Display.
