The iPhone 13 Pro / Pro Max was the first iPhone to have a ProMotion display driven up to 120Hz, but it didn’t achieve the expected always-on display.
Ross Youngs of DSCC, who is familiar with display technology and the industry, explains why this is done by answering questions.
The display of iPhone14 Pro is variable from 1Hz to 120Hz
Joe Rossignol, senior news reporter for MacRumors, told Ross Young on Twitter, “Can you tell us from a technical point of view why the iPhone 13 Pro couldn’t achieve a constantly lit display? The iPhone 13 Pro uses ProMotion. Can we expect even higher power efficiency from the A16 chip? “
To this question, Young said Rossignol’s view was correct, because the refresh rate of the display installed in the iPhone 13 Pro series is variable from 10Hz to 120Hz, and I did not want the display with a refresh rate of 10Hz to have a constant lighting function. Is answered.
It is rumored that the refresh rate of the display installed in the iPhone14 Pro series will be variable from 1Hz to 120Hz.
Right, they don’t want to implement it in a display with 10Hz refresh. 1Hz will be a much more efficient implementation.

Is it realized by a combination of 1Hz refresh rate and A16?
The base model iPhone 14/14 Max is equipped with the same A15 chip as the iPhone 13 series, and it is said that only the iPhone 14 Pro / Pro Max will be equipped with the new A16 chip.
The combination of a variable refresh rate of 1Hz to 120Hz and an A16 chip will realize a constantly lit display.
Young has previously commented that the display refresh rate on the iPhone 14 Pro series can be as low as 1Hz.
