The retina is just a technology, not a screen material. Finally, the IPS screen used by Apple is also a TFT. However, Samsung's own super amoled and super amoled plus screens are used by Samsung. Besides, the retina display technology of mobile phone screen is a patent of Apple, and no one can use it without the authorization of Apple.
Apple will continue to use Retina display in new products, including Apple TV. For all Apple devices, color consistency and accuracy are more important than anything else, and Apple will launch Apple TV based on this strategy.
The so-called "retina" is a display technology, which can compress more pixels into one screen, thus achieving higher resolution and improving the fineness of screen display. Developed by Motorola. This technology was originally used on Moto Aura. This resolution is enough to make people unable to distinguish a single pixel under normal line of sight. Also known as retina display screen.
Take MacBook Pro equipped with Retina display screen as an example. The resolution contrast diagram of Retina shows that the graphics card renders 2880x 1800 pixels at work, and every four pixels are a group, and the image is output in the size area displayed by one pixel on the original screen.
In this way, the icons and characters seen by users are the same size as the original 1440x900 resolution display screen, but the fineness is four times that of the original display screen. However, for special elements such as video and images, one picture pixel corresponds to one screen pixel. Therefore, it will not cause the problem that the screen text and images become smaller and difficult to read because of the improvement of resolution in Windows.
In this way, when designing software, we only need to increase the fineness of all UI elements to four times, which can not only maintain the viewing comfort, but also improve the display effect.
