Samsung inkjet process boosts iPhone 14 Pro display life span

Samsung Display is Apple’s biggest OLED panel supplier for the iPhone 14 lineup of devices. This year’s iPhone 14 Pro and Pro Max models completely ditched the display notch in favor of pill shape cutout, for which, Samsung played a key role with additional inkjet process.

According to TheElec report, Samsung Display utilized additional inkjet equipment in the entire process of mass-producing OLED display panels for the Apple iPhone 14 Pro and Pro Max devices, which is different from the process used in standard and Plus models.

The iPhone 14 Pro and Pro Max’s OLED display is manufactured using additional inkjet equipment after forming thin film encapsulation and touch electrodes (Y-OCTA). Samsung D used inkjet equipment only for TFE (thin film encapsulation) process that protects iPhone 14 (non-Pro) and iPhone 13 OLEDs from moisture and oxygen.

The additional inkjet process is required in OLED production as iPhone 14 Pro introduces pill shape hole display for the first time. A hole must be drilled in the post-process (module process) to bring a hole (hole) for the front camera lens on top of the OLED.

Due to this additional change in display, the Korean tech giant reportedly made thin film encapsulation and touch electrodes in the iPhone 14 Pro lineup OLED. Followed by, it used inkjet equipment to build a dam separating the hole part from the rest area and to flatten the uneven height part.
