As expected, Apple launched three new smartphones. The 2018-2019 lineup includes the OLED iPhone XS and XS Max and the iPhone XR which uses an LCD display.
The iPhone XS is the successor to the iPhone X - this phone sports a 5.8-inch 1125x2436 flexible notch-type AMOLED display (produced by Samsung Display), 4GB of RAM and 64/256/512 GB of storage.
IHS posted an interesting article which details a new backplane technology that Apple is developing. So-called Low-Temperature Polycrystalline Oxide (LTPO) combines both LTPS TFTs and Oxide TFTs (IGZO, Indium Gallium Zinc Oxide). LTPO is applicable for both OLED and LCD displays.
In LTPO, the switching circuits are using LTPS while the driving TFTs will use IGZO materials. This could lead to a power saving of around 5-15% compared to the currently-used LTPS backplanes. The main drawback of LTPO, however, is that the IGZO TFTs are larger and so the display density may be compromised. IHS says that Apple may introduce this into future iPhones - but it also says that LTPO will be limited to low-density displays at first which is a bit confusing.
