Is it necessary for iPhone to reach 120 Hz screen refresh rate next year?

According to the latest report released by DIGITIMES, next year's 5g smart phones, including the iPhone, will be greatly upgraded in screen refresh rate. In 2020, the iPhone will have the same promotion screen as the iPad pro, with a refresh rate of 120Hz, but the iPhone will be an OLED panel with high refresh rate, while the iPad will be an LCD screen.

The news is in line with the July OLED screen supply chain revelations, both claiming iPhone ProMotion technology next year. So far, Apple has not implemented ProMotion. in any OLED screen products

Apple first adopted 120Hz screen refresh rate on 10.5-inch iPad pro and 12.9-inch iPad pro in 2017, doubling the refresh rate greatly improves the response speed of user experience, user gestures can be converted to on-screen actions faster, which means more smooth rolling and sliding feeling. 120Hz also allows the screen to accurately present 24 fps, 48 FPS and 60 FPS video content.

On the current iPhone screen, the 60Hz refresh rate does not evenly display every frame of 24fps video, because 60 / 24 is a fraction result. Therefore, it is necessary to make up for the insufficient number of frames by repeating frames or inserting artificial frames.

On the ProMotion screen, it can display each frame of 24FPS video at the same duration, thus obtaining a more fluent video viewing experience.

There are already several Android phones with 90Hz screens on the market, including the latest Google Pixel 4, and the Asustek ROG is the first mass-produced 120Hz OLED smartphone. This suggests that the technology to achieve ultra-high refresh rates on the OLED screen at least already exists, and that Apple seems likely to use it in the OLED iPhone family in 2020.

So, is the 120Hz refresh rate that necessary for iPhone?We think it depends on whether Apple can provide enough conditions for iPhone's ProMotion, otherwise the cost will not be proportional to the revenue.

A higher refresh rate can improve the response speed of the device. However, the significance of promotion lies not only in speed, but also in the way speed is realized.

ProMotion can intelligently accelerate specific areas of display, rather than always accelerating the entire screen. On iPad Pro, if the user uses Apple Pencil to draw on a corner of the display screen, the screen refresh rate in that corner will increase. The rest of the screen continues at a normal speed of 60 Hz, or can even be reduced to 24 Hz for areas such as static toolbars or site titles.

This is the "adaptability" of ProMotion, the display screen can bring maximum value to users, provide additional refresh rate, and at the same time minimize the power consumption required for high refresh rate.

This is undoubtedly revolutionary for iPad Pro when using Apple Pencil.

On the other hand, because iPhone, is shared by iPad, iOS game Apple attaches more importance to its "diversity" than "professionalism", so as a regular phone that is neither professional view creation nor professional game hardware, it actually does not get any special benefits from the 120Hz display. Most users who use iPhone do not care which is more follow-up between the 90Hz screen and the 120Hz screen.? Nor will you pick the number of frames when you watch the video on your mobile phone.

Of course, we don't deny the progressive significance of iPhone's adoption of ProMotion OLED, but we also have to admit that because of this demand, it increases the workload of screens and GPU, consumes more power, and costs more. With the cost of the 5G iPhone already high, if you want to see a more aggressive new iPhone, you have to be prepared to see a higher price.

Don't forget that iPhone 11 has just used "price" to pull back consumer sentiment, and for eager fruit fans, if iPhone's "innovation" and "price" are not equal, Apple may have to cry about sales again.
