We hear about the ProMotion technology with frequency up to 120Hz arriving on the iPhone for years now: but even if it has been indicated several times for this year's iPhone 12 it seems that perhaps we should wait until 2021 because to implement it, without penalizing consumption of energy and autonomy, low consumption LTPO displays are required. This component is expected to arrive on a top Samsung terminal later this year, but is expected to land on the iPhone only next year.
For days it has been rumored that one of the news that we should see in the new iPhones that will be presented before the end of the year, the refresh-rate ProMotion of the screen up to the frequency of 120Hz, a peculiarity probably reserved only for the iPhone 12 Pro, in other words the models from 6.1 and 6.7. LiPhone 12 will be able to vary the refresh rate of the screen, lowering it to show more static images and screens, and increasing it up to 120Hz for movies and games, in order to better optimize the battery, using the refresh rate or vertical frequency) appropriate as appropriate.
The indiscretion is not new and began to circulate in 2019 when a leaker from the Samsung world known as "Ice Universe" on Twitter reported that Apple was considering the use of 60Hz / 120Hz refresh rate technology for the iPhones of 2020. In October, in a report from the Taiwanese DigiTimes website, the indiscretion was corroborated, stating that it would arrive on this year's top-of-the-range iPhones. Other rumors have recently come from h Max Weinbach and Jon Prosser: the latter also reported that Apple could disable ProMotion at the software level before the launch of the device if the functionality proves to be too expensive in terms of battery consumption.
The latest news on this front comes from the analyst Ross Young, specialized in display, who in a tweet reports that Samsung Galaxy Note20 + will be the only top-of-the-range smartphone this year to boast LTPO, a display technology that allows you to reduce energy consumption. The current OLED screens use a hardware layer called LTPS TFT formed by low temperature polysilicon.
Instead LTPO TFT uses low temperature polycrystalline oxide, helping to reduce consumption. Samsung and LG Display are the companies that currently build iPhone OLED schemes. According to Ross Young, if Apple wants to integrate ProMotion technology in iPhones, it must implement LTPO technology, since it allows a variable refresh rate starting from 1Hz with the device inactive, for example to show the time, up to a maximum of 120Hz for content more dynamic like movies, videos and games. Like what happens with Apple Watch 5 equipped with an LTPO screen, you could get an alwayson display, always on and visible.
For 120Hz, you need LTPO which enables variable refresh so you can operate at 1Hz-120Hz and optimize battery life. Only one flagship phone will have LTPO. Will leak it tomorrow with display specs.

Below is Apple's description of LTPO technology when implemented on Apple Watch 5 The architecture of the pixels in the LTPO display (low temperature poly-silicon and oxide) (…) allows the refresh rate to drop from 60Hz to just 1Hz when the watch is not active. Thanks to the team play between the low consumption driver, the ultra-efficient energy management and the ambient light sensor, the battery lasts up to 18 hours even if the display is always on.
There are already some Android terminals in circulation that point to video players with 120Hz screens but with shared energy: to offer this technology that Cupertino has christened ProMotion on iPhone without penalizing autonomy Apple may want to wait for the arrival of an OLED screen LTPO. According to the analyst for this year only Samsung will make this type of OLED screen and use it on its terminal, while for iPhones we must wait for 2021. So even if the ProMotion screens have been available on iPad Pro since 2017 and for years it has been anticipated the arrival on the iPhone, we probably should still wait until the iPhone 13 of 2021 to be able to have this technology on Cupertino's smartphones.
For all you need to know about the current iPhone 11 and 11 Pro, we refer to this in-depth analysis of macitynet. For new models arriving this year, however, it is possible to consult this article for iPhone SE 2 or better iPhone 9 as it will probably be called the economic terminal expected within the first months of this year, instead all that has emerged so far on the iPhone 12 5G summarized in this article.
