They spent 100 million dollars to make you look comfortable

In early October, the Google pixel 4 series of mobile phones was released. In addition to the daily comparison of photos and appearance, the 90 Hz high refresh rate screen is the biggest highlight. < / P > < p > in the first half of the year, one plus seven Pro took the lead in using the 90 Hz screen as a non game mobile phone and got the displaymate a + rating. However, in the first half of the year, a number of mobile phones used the 90hz screen, which seems to mark the early arrival of the screen revolution. < / P > < p > Hz is actually the frequency. All moving pictures we see are composed of frame by frame images. The number of frames that can be flipped in one second represents the number of Hz. Let’s take a computer monitor as an example. Whenever you need a large-scale game, the old birds around you will make you close your eyes at 144hz. The difference between it and ordinary screen is probably the following picture. < / P > < p > in the game, visually speaking, if the 144hz enemy moves to your side in a continuous manner, then 60Hz will jump and flash to your side. Who can stand this? < / P > < p > the truth on mobile phones is the same. Although we will not have the demand for large-scale games like computer terminals, it is true that high refresh rate will transmit more information to us than low refresh rate, and the game screen will look more coherent. < / P > < p > for example, it is more smooth and not easy to be bored when reading text; when watching some high frame video, the mobile phone picture can show more completely and capture more details; when playing some real-time games, you can also turn on the high frame rate mode to get a more immersive experience. < / P > < p > as mentioned earlier, a 90hz screen requires 90 images per second. However, today’s apps often adapt to a 60Hz screen, that is, only 60 images are prepared. < / P > < p > then all of us who have read primary school must have found the problem, 90-60 = 30, there are 30 pictures missing in one second! < / P > < p > in order to show the consequences more intuitively and make it easy for everyone to understand, the sophomore went to the next door and Tony simulated this scene of low refresh rate and strong high refresh rate in actual shooting. < / P > < p > if you look carefully, you can see the same scene. Is it because the materials given in the above figure are not enough to support us to see all the details, naturally it seems to be a drag. < / P > < p > therefore, in order to better conform to the public, most manufacturers can only accommodate those 60Hz apps in many cases even if their hardware has reached 90hz. < / P > < p > as the first batch of manufacturers to apply 90hz screen in China, the mobile phone manufacturers have done the same action as the pioneers in other industries since they joined the company. They have specially formulated a set of 90hz application certification system. < / P > < p > this application certification system gives the current application market a standard, ensuring that every animation and function can have the most perfect performance on the 90hz screen in the daily application through the system. < / P > < p > in other words, Yijia wants to be the pioneer and popularizer of 90hz application standard, and wants to push the whole application industry forward with its own actions. < / P > < p > at present, more than 500 commonly used applications have completed the test and certification of one plus 90hz, and Yijia is also cooperating with Tencent to upgrade 60-90hz on many games. < / P > < p > in order to make its 90hz fluid screen smoother, Yijia mobile phone has also made a series of deep optimization on the hardware and software for the 90hz fluid screen. < / P > < p > also gives it the literary name “one plus 90hz Bach algorithm rate”, hoping that the mobile phone can be used as smoothly and elegantly as Bach’s music. < / P > < p > a set of underlying performance scheduling algorithm of native Android system is written. This algorithm will exert the powerful power of flagship chip, and allocate the maximum performance resources for the application running in the foreground. < / P > < p > the intuitive embodiment is that the sliding operation is much faster than the naked eye. The official data response time is 40 ms, which is 38% faster than the ordinary 60Hz Android phone. < / P > < p > you can save 48 seconds by sliding 2000 times a day, which is 4.86 hours a year, which saves you a lot of thinking about smashing your mobile phone because it is not fast enough. < / P > < p > as the saying goes, “no 2K, no a screen”. With 7T pro, this AMOLED screen is equipped with 2K +, which directly enlarges the display effect and makes it clearer and smoother. < / P > < p > as a matter of fact, the adaptation of 90hz screen is not so simple as hardware upgrading, but a series of detailed optimization is essential. < / P > < p > when major manufacturers were trying to get as close to OS as possible, they chose hydrogen OS, which is more concise, efficient and more devoted to the original Android. < / P > < p > in our own hydrogen OS system, we have combed the daily commonly used animation and interactive scenes in detail, optimized each animation frame by frame for 90hz, and finally made the sense of fluency in the forefront of Android. < / P > < p > another thing that the sophomore likes is that hydrogen OS gives users very high permissions. If you have any app you don’t like, it doesn’t matter if you bring it with you, but it’s OK to delete it. It’s really enjoyable. < / P > < p > in the latest system, the missing multi-functional NFC has also been made up, and the in car voice assistant icon has been added, the photo album has been updated, and a “Zen mode” has been set up to help you get rid of your mobile phone dependence. < / P > < p > back to the previous topic, there are more and more mobile phones with 90hz screen, but it is not necessarily 90hz that is marked with 90hz. It is not only the screen that makes it difficult to return once it is used. It needs a whole set of system optimization and a careful grasp of each frame. < / P > < p > we also hope that when the 90hz mobile phone on the market becomes a standard configuration, we will remember this brand which takes the lead in reform and strives to promote the progress of the whole industry.
