![]() This name was applied to the LCD screen of the iPhone XR. The HD and Super HD labels are earned with a higher resolution. Note that these extended versions of the retina are not necessarily defined by the pixel density/distance equation in the same way as the retina itself: You will find that the Retina HD iPhone 6, 7 and 8 all have 326ppi screens, just like the normal Retina iPhone 5 and 5s. The same name applies to the iPhone XS and XS Max. With its 5.8-inch, 2436 x 1125, 458ppi screen, the X was considered the latest version of the Retina branding: Super Retina HD. This label continued into 2017 up to and including iPhone 8 and 8 Plus.īut with the arrival of iPhone X shortly after the 8-generation smartphones, Apple went one step further. iPhone 6 Plus has a vertical resolution of 1080 pixels, exactly the number of pixels needed for the higher of the two HD video standards.Īpple has awarded the iPhone 6 and 6 Plus with the Retina HD label. When iPhone 6 came out in 2014, it had a vertical resolution of 750 pixels, slightly more than the 720 pixel vertical resolution that is one of the standards for HD video. What’s the next step? How do you describe a screen that’s even better? Apple’s answer was to adopt terminology from the video and broadcast industries. Steve Jobs drew Apple into a corner when he described the pixels on iPhone 4 as imperceptible to the human eye. The text in particular benefits from retina – it looks smoother, with the curves on the characters looking like curves rather than jagged steps. The effect of a retina display is that everything looks clearer. How does a retina display differ from a non retina display? ![]() To compensate for this, Apple has developed the so-called HiDPI mode, in which each UI element is twice as large vertically and horizontally, and thus the same size as on a non-Retina display. User interface elements such as menus and icons would look tiny. If they did that and nothing else, however, there would be a problem. Simply put, Apple converts a device’s display to retina by doubling the number of pixels vertically and horizontally, which means it has four times as many pixels as its non-retina counterpart. So you can see that everything is a little vague – but the rough idea is that a screen is classified as retina when it’s sharp enough that the human eye can’t see individual pixels at a typical usage distance. But it qualifies as a retina because you’re sitting further away from a laptop screen. ![]() iPhone X, XS and XS Max have a pixel density of 458ppi.īut look at the 13 MacBook Pro and its screen has a density of only 227ppi. In general, the larger the screen, the further away your eyes are likely to be from it and the lower the pixel density required to “qualify” as a retina display.įor example, iPhone 4, 5, 6, 7 and 8 all have screens with a pixel density of 326ppi, while the Plus versions have a higher density of 401ppi. The further away their eyes are from the screen, the lower the pixel density needed to make the pixels disappear. How can you call them all retina?īecause there are two crucial elements whether pixels are perceptible or not: density and distance. Some have pixel densities greater than 326ppi, others less. Since then, Apple has launched many more devices with retina displays. They don’t see any pixels, only the image that created them. When Steve Jobs launched iPhone 4, the first Retina display, he described it as a screen with so many pixels so close together (it was rated 326ppi – pixels per inch) that they were invisible to the human eye at a distance of 12 inches. The first and most important criterion is pixel density: the statistic that generally gives the best idea of the sharpness of a screen. We’ll give you an idea of whether retina displays are worth the price you pay. In the following article we will discuss Apple’s retina displays a little more closely. However, there are features that distinguish retina displays from non retina displays. Retina is an Apple brand term for which there is no concrete definition: Simply put, a Retina display is any screen developed by Apple.
