Quote:The 2020 iPhone generation could bring substantial upgrades, including in the display department.
 
A recent leak suggests that Apple could use 120Hz panels on the 2020 iPhone, which would technically mean that the Cupertino-based tech giant wantss to expand its ProMotion technology beyond the iPad Pro.

ProMotion debuted on the iPad back in 2017, offering major improvements in terms of display response and features like scrolling. With a 120Hz refresh rate, Apple could also allow the use of an Apple Pencil on the iPhone, albeit this is just a guess for the time being.
 
Ice Universe, who has a good track on mobile scoops, says Apple wants to use a switchable refresh rate on the next-generation iPhone coming in 2020.
