LG's Display division is expected to assist Apple in developing a future iPhone. According to a report by the Chinese version of DigiTimes, LG is working on developing foldable displays, which could very well be for a future folding iPhone.
The source claims that LG Display is currently working with Apple on a foldable OLED panel for Apple's future iPhones. The division at LG, however, is only currently working on a prototype, and it's unclear whether if LG will supply its display for mass production to Apple once it has been developed.
Earlier, Samsung was rumoured to supply OLED panels to Apple after the launch of the iPhone X – its first iPhone with an OLED panel. There were rumours that Samsung will supply Apple with foldable panels last year, so it's unclear how Apple's decision to commission LG to develop foldable displays fits into this. We also recently reported that Samsung will supply LTPO panels to Apple for this year's iPhones to enable the long-awaited Always-On functionality along with a 120Hz refresh rate.
Sources suggest that the first foldable iPhone will arrive by the end of 2023, and it will feature Apple Pencil support. While manufacturers like Samsung, Motorola, and Huawei launched its foldable phones starting in 2019, Apple seems to be late in the day.
