Apple asked Samsung to use a different production method for the OLED display

The OLED screen of the iPhone 14 Pro and Pro Max was more complicated to produce due to the pill-shaped cutout. Apple even asked Samsung Display to use a more advanced production method for these screens.

The iPhone 14 Pro we tested and the iPhone 14 Pro Max have a unique feature compared to the iPhone 14 and 14 Plus. Their OLED screen has a pill-shaped cutout that accommodates the Dynamic Islandthis new feature that blurs the line between hardware and software. This is a dynamic notch that allows the black space of the front camera and Face ID sensor to expand to display information. It’s quite practical, but the manufacture of the OLED panel with the pill-shaped cutout was not so easy.

The OLED panel of the iPhone 14 Pro and Pro Max was manufactured by Samsung Display, the subsidiary of Samsung specialized in screens. Samsung had to adapt its production methods to create this screen with a cutout. In a new report, The Elec claims that Apple asked Samsung to use a different production method.

Samsung built a kind of dam to protect the pixels around the iPhone 14 Pro’s screen cutout

The main challenge of the iPhone 14 Pro’s OLED screen is to successfully drill a hole in the slab without damaging the surrounding pixels. You also have to be careful not to expose the pixels to humidity and oxygen. In its report, The Elec explains that Samsung has built a sort of barrier that separates the cutout from the surrounding pixels.

To make a hole for the front camera sensor, etc., at the top of the OLED screen, a hole must be drilled in the post process (module process). If the thin-film encapsulation is damaged, the OLED is exposed to moisture and oxygen, and the product life is greatly shortened explains L’Elec.

To manufacture this OLED panel, Samsung used inkjet equipment which allowed him to build this dam which separates the hole from the rest of the screen. Incidentally, Samsung was able to do this using a laser, but Apple would have preferred the inkjet equipment method.
