We’ve been hearing for a while that iPhones will be shifting to 120 Hz this year, and today a recent article from Korea roughly confirms it while also adding some interesting new details.
The new LTPO AMOLED displays with 120 Hz refresh rates are said to be exclusive to the iPhone 13 Pro and iPhone 13 Pro Max and will be manufactured by Samsung. Furthermore, Samsung Electro-Mechanics can include rigid-flexible printed circuit boards (RFPCB).
Youngpoong Electronics, a South Korean PCB manufacturer, is also expected to supply RFPCB to Apple through Samsung Display. Youngpoong was introduced to the supply chain because Samsung Electro-Mechanics might leave the RFPCB segment after the release of the iPhone 13.
In 2019, Youngpoong supplied RFPCB to Apple via LG Display. However, its stock of iPhone boards fell last year after Cupertino opted to make LG Display use multiplex FPCB for its OLED panels instead of RFPCB.
A 120Hz refresh rate screen necessitates the use of LTPO OLED. Samsung Display will be the sole supplier of these displays.
According to Omdia reports, Samsung Display will supply 110 million OLED panels for iPhones (both iPhone 12 and iPhone 13) this year, followed by LG Display at 50 million and BOE at 9 million. The exact number of OLED panels supplied to Apple for the iPhone 13 will not be known until July, when manufacturing starts.
