Apple wowed its collective fanbase with the introduction of the iPhone 14 Pro series Dynamic Island, an effort to make the giant OLED display cutout actually serve a useful purpose. Apart from the aesthetics side of it, of course, as the Dynamic Island cutout on the iPhone 14 Pro and iPhone 14 Pro Max is less of an eyesore compared to the notch that Apple has been using to house the Face ID components for years on end now.
The Dynamic Island feature is still a software and user interface solution, though, while the hardware behind it comes courtesy of Samsung which managed to deliver an OLED panel of its latest and brightest generation to Apple with the requested quality and consistency that the giant holes in the panel required.
It’s precisely because of Apple’s insistence, reports Korean media The Elec, that Samsung was forced to widen its inkjet printing method in order to seal the iPhone 14 Pro line’s display cutout edges, so that oxygen or moisture can’t get in to shorten the panel’s lifespan dramatically.
Instead of only using the OLED inkjet printing deposition method during the lamination process, like on the iPhone 13 series, or the iPhone 14 and 14 Plus, Apple asked Samsung to deploy it for the touch layer as well for added durability.
Samsung said that it can make do with only laser cutting and sealing, but Apple wanted it to use inkjet printing to seal the Dynamic Island edges and create a “dam” separating them from the rest of the OLED panel, while evening out the inevitable height advantage of the edges resulting from piercing the cutout in the uninterrupted panel.
Long story short, Apple demanded that Samsung do something it hadn’t done since it used the inkjet printing method for the entirety of the sealing process on the Galaxy S21 Ultra last year, and that one only has one small round opening for the front-facing camera.
