Apple asked Samsung, the largest display supplier, to use a special method to protect the iPhone 14 Pro’s screen from possible damage and loss of image quality.OLED inkjet process applied
The iPhone 14 Pro and 14 Pro Max are the first iPhones to feature a punch-hole directly inside the screen, unlike other iPhones. To create the pill-shaped hole in the screen, Samsung needs to create the hole directly inside the OLED panel, but this can result in the screen being exposed to moisture and oxygen if the surrounding pixels and panels are damaged. Samsung had to use an additional inkjet printing process to avoid this.
Samsung used the OLED inkjet process for the flat iPhone 14 models and iPhone 13 series during the thin-film coating process. However, the iPhone 14 Pro series used additional inkjet equipment on the TPE and touch layer to increase screen durability and lifespan. The equipment Samsung uses to manufacture Apple’s display is owned by SEMES, a subsidiary of Samsung Electronics.
LG Display also provides display
It is known that LG Display also applies the same method for the iPhone 14 Pro Max screen. Although LG Display has some issues meeting the iPhone 14 Pro Max display requirements, it seems to have been resolved. While Samsung provides two types of screens, the 6.1-inch 14 Pro and 6.7-inch 14 Pro Max models; LG Display only provides the screen for the 14 Pro Max.
