The hype surrounding the iPhone 12 series has not yet faded off and we're starting to hear details on the iPhone 13 and iPhone 13 Pro models. Apple doesn't seem to rest when it comes to introducing new tech. The entire year we were expecting Apple to bring a higher refresh rate display to the iPhone 12 series. Most of the reports mentioned that only the iPhone 12 Pro models will feature a higher refresh rate. However, that did not pan out. Now, it is being reported that Apple will adopt LTPO technology which will enable the iPhone 13 Pro models to bolster the 120Hz refresh rate.

Yes, you've read that correctly, only the Pro models of the iPhone 13 will feature a 120Hz display thanks to the LTPO technology. According to the Korean website The Elec, only the Pro models out of the four will feature a 120Hz display while the standard models will stick to 60Hz. The report further mentions that LG and Samsung will remain Apple's top suppliers for the iPhone 13's display. However, the Chinese company BOE is also targeting to land some orders from Apple.
