The 2022 iPhone 14 Pro flagship models feature a new punch-hole display with a smaller notch and hole for the selfie camera. The new display design required the formation of thin film encapsulation and touch electrodes (Y-OCTA) to protect the OLED panels from moisture and oxygen. Therefore, Samsung Display used additional inkjet equipment.

In this year’s iPhone 14 Pro lineup, inkjet equipment was additionally used after forming thin film encapsulation and touch electrodes (Y-OCTA).

This is because of the first hole display applied to the iPhone 14 Pro lineup. To make a hole (hole) for the front camera lens, etc. at the top of the OLED screen, a hole must be drilled in the post-process (module process). It can be. If the thin film encapsulation is damaged, the OLED is exposed to moisture and oxygen, and the life span of the product is drastically shortened.

The report details that Samsung could have used the laser equipment to build a dam to separate the hole from the rest of the area after thin film encapsulation and flatten areas with uneven heights but the manufacturer used the inkjet method because Apple preferred the latter.

To avoid damage to the thin film encapsulation (which protects the OLED from moisture and oxygen) in the process of making the hole display first applied to the iPhone 14 Pro lineup. Apple’s request also played a role in the adoption of the inkjet method.

A subsidiary of Samsung Electronics, SEMES provided all the inkjet equipment for mass production of iPhone 14 Pro OLED panels at Samsung Display’s A3 line. It is reported that LG Display also used the same method for the production of OLED displays for the iPhone 14 Pro Max.
