Some of the most important parts of the next iPhone won't be made in China

"Designed in California. Made in China" – is what it says on the iPhone's back. But the display, a key and defining part of the upcoming OLED iPhone's design and functionality, is going to be all Korean. It's a public secret that Samsung Display is supplying the lion's share, if not the entire volume of orders for the phone's rumored "all-screen" display panel.

But The Investor reports that Samsung Display, in tandem with several key supplies both under and outside the Samsung umbrella, is responsible for the entire screen assembly. Samsung System LSI, the semiconductor division that manufactures camera sensors and application processors, is also going to build the display driver chip.

South Korea should change its national flag to an OLED screen.

STEMCO and LG Innotek, both Korean companies, will deliver the chip on films that connect it to a flexible printed circuit board – one provided by Interflex, BH, and Samsung Electro-Mechanics. All three companies hail from South Korea as well.
