Super Retina XDR OLED Displays
That said, there’s more to the reduced display borders than just the change to a flat-edged design; Apple’s switch to using OLED displays in its entry-level iPhone lineup undoubtedly played a big part in this as well, since with the advanced engineering Apple put into its Liquid Retina LCD display for the iPhone XR and iPhone 11, it still couldn’t match the much more edge-to-edge display of the flagship OLED models.
This year, however, Apple has gone all-in on OLED across its entire lineup, bringing its Super Retina XDR display to the standard iPhone 12 models. While the specs won’t be a huge surprise to iPhone 11 Pro users, it does mean that those opting for the more affordable model will get the same 2,000,000:1 contrast ratio, 458ppi pixel density, and 1200-nit peak brightness, as well as support for HDR video formats such as Dolby Vision and HDR 10.
