Samsung Display, one of the main suppliers of displays for Apple’s mobile devices, is reportedly working on new technologies for the iPhone 16. However, for the upcoming iPhone 15 series, it seems that Samsung will be reusing the same OLED material set used for the iPhone 14.
According to sources cited by The Elec, Samsung Display will be using a material set known as M12 for the iPhone 15 series. This same material set was also used for Samsung’s folding smartphones and the iPhone 14 Pro and Pro Max models. However, the iPhone 14 and Plus models used an earlier M11 material set.
The OLED material set refers to the light-emitting layer, the common layers, and the prime layers of individual pixels that make up the OLED display. A different material set varies the composition of these components.
Although the reuse of a material set is not uncommon, Samsung is reportedly developing new ones as well. The report claims that Samsung Display is also working on M13, a new material set that will be used by Samsung and its clients besides Apple, and M14, a material set specifically for Apple anticipated to be used on the iPhone 16 in 2024.
While the iPhone 15 will apparently all use M12, they will differ in terms of the underlying technology. The non-Pro models are expected to use low-temperature polycrystalline silicon (LTPS) thin-film transistors (TFT), a low-technical difficulty technology. Meanwhile, the Pro models will use low-temperature polycrystalline oxide (LTPO) TFT instead, which is a harder-to-produce version.

Samsung Display is the display supplier for all iPhone 15 models, with LG assisting in the production of the Pro models. BOE was initially slated to produce displays for the non-Pro models, but due to production issues, Samsung started screen production earlier to compensate.
While the details of the upcoming iPhone 15 series are still mostly shrouded in secrecy, it is exciting to know that Samsung Display is working on new technologies for the iPhone 16, which is still a year away. It remains to be seen how these new technologies will enhance the display capabilities of Apple’s flagship smartphone.
