All of us are always overwhelmed by Apple products and we love those amazing and unique features of Apple. The New iPad with Retina display is already in news but the term Retina display is not new. Apple has already introduced the Retina display feature with iPhone 4 that released on June 24, 2010.
Retina Display: The Definition
If you look closely at a regular display screen, you can easily make out some individual pixels. A Retina display is packed with high density pixels that making individual pixels is indiscernible from a normal viewing distance. “Retina display by Apple has a high enough pixel density that the human eye is unable to notice pixelation at a typical viewing distance.”
The Retina display on iPad features a 2048 × 1536 resolution, that’s four times the number of pixels in iPad 2 and a million more than an HDTV. Those pixels are so close together; your eyes can’t discern individual ones at a normal viewing distance. When you can’t see the pixels, you actually touch your photos or read a book. This is what Apple tries to make you believe.
Retina Display – A Marketing Term
Apple introduced a resolutionary feature with the launch of iPhone 4. The mobile device was marketed for its “FaceTime” video calling feature and high resolution screen. The Retina display is just a marketing term and does not refer to a worldwide standard or display technology. It simply means that the screen has sufficient pixel density that you can’t make out all the individual pixels. Retina is a term coined by Apple and Apple has also registered the name “Retina” as a trademark. However, the displays are manufactured by LG or Samsung.
Retina Display on Different Devices
The amazing display is available on several Apple products, including the iPhone, iPod Touch, iPad, and MacBook Pro. When Apple says that pixels are not distinguished at a normal viewing distance, it does not specify a value for the normal distance. Retina display states no specific definition and Apple is able to use the term how it wants.
It all depends on the size of the display and each device’s usage. Apple claims that the normal viewing distance is around 10-inches when you looking at the iPhone 4 which holds 326 pixels per inch. The New iPad display is able to produce pixel density of 264 pixels per inch which is significantly less than that iPhone 4 “retina display”. However, it’s twice that of the iPad 2 and Apple still calls it “Retina display”. This is because the distance is 15-inches for an iPad.
To deliver a Retina display at 10-inches you need to pack in more than 300 pixels per inch, but at 15-inches you can get an identical effect with considerably fewer pixels. The iPhone 4S has 326 pixels per inch, and the new iPad delivers the same quality with 264. At least that’s what Apple would like you to think.
