Reports of the iPhone 13 Pro and iPhone 13 Pro Max featuring a high refresh rate, LTPO displays have been consistent for months. This will eventually make the two models the first from Apple to feature 120Hz screens, with Samsung and LG expected to be Apple’s suppliers for this display technology. Unfortunately, a new report claims that LG won’t be able to provide the iPhone giant this key component, so it’s up to Samsung to cover up the remaining shipments, once again becoming Apple’s chief supplier.

It’s not confirmed why LG has reportedly opted to deliver LTPO panels from next year, but The Elec states that Samsung is expected to convert part of the A3 production line in Tangjeong, Asan, Chungnam to the LTPO TFT line. This line's maximum production capacity is 105,000 sheets monthly, with conversion expected at 60,000 units per month to the LTPO TFT production line.
