The iPhone 14 Pro and iPhone 14 Pro Max are the first iPhones with a cutout directly into the screen, unlike other iPhones, which have a notch that extends down from the top edge. The report says Apple asked Samsung to use additional inkjet equipment when producing its high-end iPhone displays to create the cutout while retaining the surrounding OLED panel.
To make the pill-shaped cutout in the screen, Samsung would have to drill the pill-shaped hole directly into the OLED panel, but doing so could damage the surrounding pixels and panels and, if so, become damaged. exposed to moisture and moisture. oxygen. To avoid possible exposure to moisture and oxygen, the report says Samsung built a dam that separated the pill-shaped cutout from the surrounding pixels. From a machine-translated copy of the report:
This is due to the appearance of the first hole applied to the iPhone 14 Pro range. To make a hole at the top of the OLED screen for the front camera lens, etc., a hole must be drilled in the post-process (module process). If the thin film envelope becomes damaged, the OLED will be exposed to moisture and oxygen and the life of the product will be drastically shortened.
For this reason, Samsung Display is known to have used inkjet equipment to build a dam that separates the hole from the rest of the area after making thin film encapsulation and touch electrodes in the iPhone 14 Pro lineup OLED, and to cover areas with to smooth out uneven heights. Samsung Display was able to perform this process with a laser rather than inkjet equipment, but it is said that Apple preferred the inkjet method.
Samsung has extensive experience in producing displays, including cutouts. The company’s own line of smartphones features single-punch cutouts that house the front-facing camera. However, with the iPhone 14 Pro, the report suggests that Apple took extra care in manufacturing the screens for the iPhone 14 Pro and iPhone 14 Pro Max to ensure the cutout wouldn’t interfere with surrounding pixels and degrade image quality.
The Electric LG Display, Apple’s other display supplier, also used the same method for its range of displays for the iPhone 14 Pro and iPhone 14 Pro Max. The iPhone 14 and iPhone 14 Plus have the same screen notch as previous iPhones, but rumor has it that next year’s lower-end iPhone series models will have the the same pill-shaped cutout for Dynamic Island like the iPhone 14 Pro.
