Apple iPhone 13 rumour round-up: What to expect from the next big launch

By Cookie Monster - 14 Sep 2021

Higher refresh rates and always-on display

3.) 120Hz refresh rates and always-on display

Apple was rumoured to be introducing higher refresh rates for the iPhone 12 last year, but the feature was delayed due to concerns over its impact on battery life and Apple not securing sufficient 120Hz driver ICs . As there are reports of Apple adopting LTPO displays for the iPhone 13, rumours are back again on seeing 120Hz displays on the new devices.

TheElec reported in November 2020 that the iPhone 13 Pro models could use LTPO display technology from LG Display. As LTPO displays are more power-efficient, they provide more battery headroom for 120Hz displays. 

However, TheElec backtracked in January this year and claims that Samsung is the exclusive supplier of the LTPO OLED panels for the iPhone 13. LG Display reportedly is only ready to supply these panels in 2022.

Analyst Ming-Chi Kuo's investor note in March suggests that the 120Hz displays will be reserved for the Pro models. This is later corroborated by TheElec when sources say LG Display will be making LTPS TFT displays for the iPhone 13 and iPhone 13 mini while Samsung will be supplying LTPO panels for the Pro models.
