According to the Korean website The Elec, two out of four iPhones 13 (obviously the Pro versions) will receive OLED displays with LTPO technology and a refresh rate of 120 Hz.
The report also says that Samsung and LG will remain suppliers. There is a chance that BOE will also produce displays for new devices, but so far it has never passed the required quality checks.
LTPO technology is used in Apple Watch with an always-on display. This is a controller that is responsible for turning on and off individual pixels on the display, which means that an Always-On mode may appear on the iPhone, when the clock, important icons, and notifications are displayed on the locked screen.
The 120Hz display was rumored to be added this year, but due to the pandemic, the required number of controllers was not produced in time. Next year Apple is simply obliged to add 120 Hz, otherwise, it’s a shame.
