iPhone 14 Pro: Dynamic Island requested a new, more complex screen manufacturing process

Apple is said to have been particularly demanding of Samsung for the iPhone 14 Pro screen, in particular by asking it to use an advanced production method. This aims to guarantee better operation of the screen in the long term, according to a report by the Korean specialized site. The Electric.

Samsung Display uses inkjet equipment for the entire iPhone 13 range and for the iPhone 14 and 14 Plus. The process is used for thin film coating tiles, which protects OLED screens against mold and oxygen. The arrival of the Dynamic Island has made the process more complex, since a hole has to be drilled in the slab (and therefore the coating has to be broken).

This hole cannot be made without precautions: if the thin film layer is damaged on the way, the screen risks being exposed to humidity and oxygen. This has the effect of considerably reducing the life of the device.

The new iPhone 14 Pro notch forces Samsung Display to use its inkjet gear a second time. The Electric specifies that Samsung has reused the process with a mini-dam separating the hole from the rest of the slab. This second step takes place after having produced the first thin film coating and once the touch electrodes have been placed in the OLED. The manipulation also aims to homogenize the whole by flattening the areas whose height is unequal.

Samsung Display reportedly believed it could perform this process using a laser rather than inkjet equipment, but Apple reportedly insisted that the Korean giant use this second method. If this is a first with Apple, Samsung is no stranger to slabs with holes (which it markets for many Android smartphones). However, Apple obviously asked him to redouble his efforts for his iPhone 14 Pro.

LG Display, another panel supplier for the iPhone 14 Pro, used the same technique. According to The Electricthis second manufacturer would only take care of Pro Max screens, where Samsung offers both formats (6.7 “and 6.1”).
