In the last few years, LG has been reportedly rumored to supply its low-temperature polycrystalline oxide (LTPO) thin-film transistor (TFT) OLED panels for the upcoming Apple iPhone series, particularly the iPhone 14. Unfortunately, the rumors didn’t see the light of the day as the new iPhone 14 series was unveiled without LG Display’s LTPO OLED panels.
As early as 2020, Samsung Electronics has already been making panels for the iPhone 14 Pro and iPhone 14 Pro Max. As we witnessed last week, during Apple’s launch conference, the display was featured in the iPhone 14 series.
However, as we just discovered today, it seems the story is about to change, as the LTPO OLED developed by LG Display for the iPhone 14 Pro Max has entered the final review stage of Apple. According to Elec, LG Display’s LTPO OLED panels have entered Apple’s final review stage and are likely to be adopted in two weeks.
According to the source, the samples provided by LG Display to Cupertino showed problems with thin-film packaging and the hole at the top of the front-facing camera. As a result, the company had to replace some materials used in the production process, and new samples of the changes are being tested for reliability.
However, if Apple refuses to accept new samples within two weeks, LG Display will have to go through a similar process again, delaying the approval time by another two weeks to a month. Meanwhile, if the LG Display receives approval in the first few days of October, mass manufacturing can begin right away, increasing orders.
On the other hand, as we know that the demand for LTPO OLEDs unexpectedly rose and competitors were hindered, Samsung Display ordered more machinery to produce them. The Standard and models use low-temperature polysilicon (LTPS) panels, which are more readily produced than LTPO OLEDs, while Apple uses LTPO OLED panels in its Pro versions.
