New research claims that Apple will add a significantly improved OLED display to the iPhone, but some years later than previously expected.

Apple could move to newer OLED technology by 2029
The improved technology is called Color Filter on Encapsulation (CoE) OLED, and key to it is that it is OLED without a polarizing layer. That layer prevents blurring on screen, but there are significant benefits if it can be dispensed with.
Apple had previously been reported to be planning to use this screen technology in its 20th anniversary iPhone, due in September 2027. However, according to UBI Research, Apple will not use CoE until its Pro model iPhones in late 2029.
