Reports from Korea suggest that Samsung Display and LG Display are starting to produce AMOLED displays for Apple's future iPads, to be announced later this year. Samsung is set to produce 11" LTPO AMOLED displays, while LG Display is producing displays for the 13" model (but LGD will also produce 11" AMOLEDs in the future for Apple).
The Elec says that both Korean makers developer 11" and 13" displays, but for some unknown reason only LGD will produce the 13" displays. This could change in the future, of course. One reason could be that LG Display has more experience with tandem OLED architectures (developed originally by LGD years ago for automotive OLEDs).
It is expected that Apple will buy a total of 10 million iPad AMOLED displays in 2024 from both LGD and SDC, with LGD getting around 60% of the orders.
