The main reason for the iPhone X and Xs to be more expensiveis the OLED display. Apple depends on Samsung for the OLED displays. As you know, Samsung has the best display in the market. They use these displays on their own flagship to stand out from other manufactures.for a while, Apple is trying to switch its display vendor. Asa result, Samsung has decided to reduce the cost of the OLED panels which it sells to Apple.
Cheaper doesn’t mean that the quality will be degraded. Samsung will be providing flexible OLED panels for 2019 iPhoneswith in-cell touch technology. These are the same “Y-Octa” OLED panels which Samsung uses on its own flagships including the Galaxy S9, S9+, and Note 9.
The reason behind Samsung’s gorgeous display is that the touch functionality built into the display instead of having to integrate “film-type touchscreen panels (TSPs)” like other display manufacturers do.This technology makes the display thinner, lighter and more cost effective.
Overall, it will bring down the cost of the upcoming iPhones.
