Apple reportedly asked Samsung to use a more advanced production method for the iPhone 14 Pro screens.

To create the iPhone 14 Pro display with the lozenge-shaped cutout at the top, Apple requested that Samsung, the company’s primary display supplier, use a more advanced production method that would protect the surrounding display from potential damage and loss of image quality, according to a new report from the elect.

The iPhone 14 Pro and iPhone 14 Pro Max are the first iPhones to feature a cutout directly inside the screen, unlike other iPhones, which have a notch that protrudes downward from the top bezel. The report says that Apple asked Samsung to use additional inkjet equipment when producing its high-end iPhone displays to create the cutout and preserve the surrounding OLED panel.
To create the pill-shaped cutout within the display, Samsung must drill the pill-shaped hole directly into the OLED panel, but doing so means there’s a chance that surrounding pixels and panels could be damaged, and if so, are exposed to moisture and oxygen. To prevent possible exposure to moisture and oxygen, the report says Samsung built a dam that separated the pill-shaped cutout from the surrounding pixels. From an automatically translated copy of the report:

This is due to the first hole display applied to the iPhone 14 Pro line. In order to make a hole for the front camera lens, etc., on the top of the OLED screen, a hole must be drilled in the back process. (module process). If the thin film encapsulation is damaged, the OLED is exposed to moisture and oxygen, and the life of the product is drastically shortened.
For this reason, Samsung Display is known to have used inkjet equipment to build a dam separating the hole from the rest of the area after making thin-film encapsulation and touch electrodes on the OLED line of iPhone 14 Pro, and to flatten areas with irregular heights. . Samsung Display was able to carry out this process using a laser instead of inkjet equipment, but Apple is said to have preferred the inkjet method.
Samsung has extensive experience in producing displays, including those with cutouts. The company’s own line of smartphones feature single-hole punched cutouts that house the front-facing camera. However, with the iPhone 14 Pro, the report suggests that Apple took great care in the production of the displays for the iPhone 14 Pro and iPhone 14 Pro Max to ensure that the cutout did not interfere with surrounding pixels and degrade display quality. the picture.
the elect says LG Display, Apple’s other display provider, also used the same method for its batch of displays for the iPhone 14 Pro and iPhone 14 Pro Max. The iPhone 14 and iPhone 14 Plus have the same display notch as previous iPhones, but lower-end models of next year’s iPhone lineup are rumored to have the same lozenge-shaped cutout for Dynamic Island as the iPhone 14. iPhone 14 Pro.
