The longevity of the iPhone 14 Pro screen worried Apple before production

Apple was concerned that the longevity of the iPhone 14 Pro display could be potentially threatened by moisture and oxygen entering the panel during production, according to a supply chain report.

Apple has reportedly asked its display maker Samsung to change part of its intended production process to reduce the risk…

The potential risk arose as a result of the switch from the notch design used on previous generations of the iPhone to the cutout used on the iPhone 14 Pro and Pro Max models. (The base model iPhone 14 and iPhone 14 Plus weren’t a concern since they, of course, have the older notch design.)

The new design requires a hole and slot to be drilled into the OLED screen, to accommodate the camera and other technology, such as the Face ID matrix. the elect reports that this creates a risk of damaging the display’s encapsulation in a way that could allow moisture and oxygen to enter, which could significantly reduce the display’s lifespan.

There are two different ways to mitigate this risk, and the report says that Samsung originally planned to use a laser-based technique, but Apple asked the company to use a method similar to inkjet printing to seal the edges of the perforated area. .

For this reason, Samsung Display is known to have used inkjet equipment to build a dam that distinguishes between the hole and the rest of the area after manufacturing thin-film pockets and touch electrodes in the OLED line of the iPhone 14 Pro. Samsung Display it could do the process using a laser, not an inkjet device, but Apple was said to prefer the inkjet method.

Conveniently, another Samsung subsidiary, Semez, actually makes Apple’s preferred gear.

It is important to stress that there is no suggestion in the report that Samsung ever made displays using the riskier method. Rather, it appears that Samsung simply proposed the technique during talks with Apple, with the Cupertino company specifying the most secure approach before production began.

Rival Korean company LG also makes OLED screens for the iPhone 14 Pro Max, but apparently always planned to use Apple’s preferred method.

Separately, some iPhone 14 users have reported seeing horizontal lines on the screen when waking up or turning on, but Apple says this is an iOS glitch rather than a hardware glitch.
