Retina Display usability function embedded in the latest Smartphone Gadjet
Retina Display screen technology is very familiar with Apple devices such as the iPad, iPhone or Macbook. Apart from Apple devices, there are currently no devices such as laptops, tablets, or mobile phones that use Retina Display technology.
Maybe from some iPhone, iPad or Macbook users, of course you are no stranger to Retina Display screen technology. but even though it doesn't feel foreign to Retina Display screen technology, do you really know what is meant by Retina Display?
For more details, please see below, what is meant by Retina Display which is commonly used on Apple devices.
Understanding of Retina Display?
Retina Display (retina display) is actually just a designation for LCD (light-emitting diode) and OLED (organic light-emitting diode) panel display technologies that are only intended for Apple devices.
Examples of Retina Displays with LCD panels can be found on the iPhone 6, 7, 8, or iPhone SE 2 and SE 3 series. While the use of Retina Displays with OLED panels, including the iPhone X, Xs, 11 Pro, 12 Pro, and so on. . .
It should be noted that the use of LCD and OLED panels is basically not only used on Apple devices. but Apple offers some sort of special criteria on Retina Displays.
A screen can be called a Retina Display because it can display images that are sharp and smooth (not broken) for the user's eyes at a normal viewing distance (about 30 cm), as reported on the Macworld page.
So it can be concluded that the sharpness of an image produced by the screen of a device called a Retina Display comes from the density of a pixel (pixel density). because the visible image is the result of a collection of a pixel.
The density of a pixel on a device screen is usually measured in terms of the unit "ppi" (pixels per inch), such as 301 ppi, 458 ppi, and so on depending on future technological developments which will continue to grow. The more pixels on the resulting screen, the more visible the image will appear, the sharper or clearer the image will be.
Regarding the early history of the Retina Display, it first appeared on the iPhone 4 with fairly dense pixel quality, which is 326 ppi. With this pixel density, the iPhone 4 at that time could display sharp image quality at a normal viewing distance of 30 cm.
Until now, Apple has issued several types of Retina Display, such as Retina HD, Super Retina HD, and Liquid Retina HD. This type of Retina Display is distinguished by screen resolution, not just pixel density. For example, the Retina HD display used on the iPhone 6, 7, and 8 series. Although the pixel density is the same as regular Retina on the iPhone 4, 5, and 5s series (326 ppi), the "HD" label is attached because the screen used has an HD resolution (750 x 1334 pixels).
That's a little explanation about the Retina Display screen commonly used on Apple devices, such as the iPhone Snartphone, iPad, or Macbook, hopefully it's useful.....
