OnePlus 7T Pro: Are You Still All Concerned about the Camera? The Display is More Interesting!

OnePlus 7T Pro: Are You Still All Concerned about the Camera? The Display is More Interesting!

In the early October, the Google Pixel 4 series of a smartphone is released, in addition to the photography and appearance, the 90 Hz high refresh rate screen is the biggest highlight.

Not surprisingly, it immediately won the excellent A+ rating from the screen review agency DisplayMate.

One plus 7 Pro, as a non-gaming mobile phone, adopted the 90 Hz screen in the first half of the year and obtained the DisplayMate A+ rating, in less than half a year, many mobile phone manufacturers introduce a 90 Hz screen, which seems to mark the advance of the screen revolution.

So what exactly is the 90Hz screen that allows mobile phone manufacturers around the world to follow suit? 

I will give you a general introduction:

In fact, Hertz is the frequency, and all moving pictures that we can see are composed of images in frames. The number of frames that can be turned over in one second represents the number of Hertz.

Like a comic booklet that is turning pages:


In a word, the frequency is higher, the picture is more consistent, so the more details are displayed.

Take a computer monitor, for example, the game veteran in a large-scale game competition will choose a computer equipped with a 144 Hz screen, and the difference between the 144 Hz screen and the ordinary screen can be seen in the following picture.


In the same movement process, there is a completely different trajectory.

On the visual aspects, if the enemy in the computer game is moving continuously on the 144Hz screen, but the 60Hz screen is jumping and flashing, how can this win the game?

The situation for the mobile phone is similar. Although we haven’t the need for the large-scale game competition in the computer, compared to the low refresh rate, the high refresh rate will send more information to us, and the game screen will be more consistent.

The experience is that every touch is smoother and more seamless.


The sensory improvement for the users is obvious.

For example, text switching is smoother and less annoying; the pictures in a high-frame video can be displayed more completely, and more details can be captured; playing some real-time games in a high frame rate mode for a more immersive experience.


Despite the above advantages, the promotion of 90Hz still encountered some small obstacles.

As mentioned above, 90 images are displayed in one second on a 90Hz screen, but the current App usually adapts to a 60Hz screen, which means only 60 images are prepared.

So the question is, 90 minus 60 is 30, 30 frames are missing in that one second!

In order to let everyone know this result more easily, we simulated the scene of a lower refresh rate material on a higher refresh rate screen in the actual shooting.

The upper part of the figure below only gives low refresh rate material but shows a high refresh rate image, and the lower part is what the high refresh rate image should look like.

If we take a close look, the upper part is far less fluid than the lower part of the same scene. This is because the material given above is not enough to support us to see all the details clearly.


If the low refresh rate material doesn't match with a high refresh rate screen, this is what it looks like!

Obviously, mobile phone manufacturers are unwilling to accept the fact that it affects the sensory experience of users, so it is unrealistic to force a high refresh rate.

Therefore, in order to better cater to the public, most manufacturers can only accommodate those 60Hz Apps and compatible them downward in many cases even if the hardware reaches 90Hz.

Not every App can show a perfect performance on a 90Hz screen.


However, compatibility is only a temporary choice. To better explore the value of the 90Hz screen is what manufacturers should do.

OnePlus, one of the first mobile phone manufacturers to apply the 90Hz screen in China has done the same thing as the pioneers of other industries - specifically developed a set of 90Hz screen application certification systems.

The application certification system sets a standard for the current application market, ensuring that every animation and function through this system can perform perfectly on a 90Hz screen.

In other words, OnePlus is committed to be the pioneer and popularizer of the 90Hz application standard and push the whole application industry forward with its own actions.

At present, more than 500 common applications have completed the 90Hz test and certification. Through the cooperation of OnePlus and Tencent, many games have upgraded from 60 to 90Hz.


For the purpose of a smoother 90Hz fluid screen, OnePlus has also made a series of in-depth improvements in the aspect of hardware and software.

Furthermore, it has a literary name "OnePlus 90Hz Bach calculus rate", implying that the use of mobile phones is as fluid and elegant as Bach's music.

OnePlus rewrites the underlying performance scheduling algorithm of the native Android system, which will play a key role in the flagship chip, allocating the maximum performance resources for the applications that are running in the foreground.

In this application, every operation related to fluency, whether it is sliding, dragging or zooming, can have a higher priority.

90 Hz on the left and 60 Hz on the right:


This is clearly reflected in the faster-sliding operation, the official data response time is 40 milliseconds, 38% faster than a normal 60Hz Android phone.

Specifically, sliding 2, 000 times a day will save 48 seconds, or 4.86 hours a year, to avoid the temptation to smash your phone because it's not fast enough.

As the saying goes, "without a resolution of 2560x1440 pixels, no AMOLED screen ", the OnePlus 7T Pro AMOLED screen equipped with a resolution of more than 2560x1440 pixels displays directly a more clear and smoother effect.


It is not difficult to understand that the adaptation of the 90Hz screen requires not only hardware upgrades, but also a series of detailed optimization.

Besides, the optimized screen and smooth operating system are also indispensable.

When all the major manufacturers were trying to adopt the operating system, OnePlus chose a simpler and more efficient hydrogen operating system that favored the native Android.


The obvious advantage is that Android Apps on the OnePlus Phone always have minimal compatibility problems, and tend to be relatively stable.

If there is any major optimization on Android, OnePlus can always complete the update in the first batch.

OnePlus is China's first brand to update Android 10

Under its own hydrogen operating system, OnePlus combed the common animations and interactive scenes in detail, optimized each animation frame by frame for 90Hz, and finally achieved a more fluent experience than Android.

Animated curves for full-screen gestures, such as exiting the application, multi-tasking switching, and sliding back, all are smooth and natural.

Moreover, another advantage is that hydrogen OS gives users a high degree of authority, because any Apps that they don't like can be deleted regardless of whether it is built-in or not, which is really enjoyable.

Such a system makes it easy to appreciate its fluency.


The latest system adds a multifunctional NFC, as well as an in-car voice assistant Icon, the albums updated, and a "meditation mode" to help you get rid of your phone's dependence.


Anyway, there are more and more mobile phones equipped with a 90Hz screen, but it does not really mean 90Hz. It is not only the screen problem that needs to be solved, but also a whole set of system optimization and detailed grasp of each frame.

At least for now, OnePlus, as a pioneer, has done a good job and has set a good example for other manufacturers.

Hopefully, when the 90Hz mobile phones become the standard on the market in the future, we will remember this brand that pioneered the change and strove to promote the progress of the whole industry.
