In the case of normal use, the phone screenRefresh rate60hz is sufficient.

The refresh rate of most mobile phone screens is 60Hz, although the refresh rate of 60Hz meets the standard of normal human eyes, but it cannot meet some high frame rate pictures. Nowadays, the hardware configuration of mobile phones is very high, and the output of more than 60 pictures every 1 second is completely stress-free, but if the screen refresh rate is still 60Hz.

The refresh rate of the mobile phone screen is described as follows:

How many times the screen can be refreshed per second. The higher the refresh rate, the better the stability of the displayed picture, and the less tired the eyes are; The lower the refresh rate, the flickering image will keep flickering, and the eyes will tire quickly.

The mainstream configuration of the screen refresh rate of the mobile phone using Yunzao Lu is 60Hz, which means that the screen displays 60 frames per second (fps). According to the visual effect of the human eye, 20-30fps is basically smooth, 30-60fps is smooth, and 60+ fps is very smooth. That is to say, the mobile phone screen currently used is visually in the range of smoothness.

The screen refresh rate is FPS (frames per second), and the refresh rate of the screen is the number of frames that flow through the screen in one second. For example, the 90Hz screen refresh rate means that the screen can be brushed through 90 screens per second.

1. Set the screen refresh rate of the mobile phone system.

60Hz (standard refresh rate): saves power consumption.

90Hz (high refresh rate): Smoother picture quality and operation.

120Hz (high refresh rate): Smoother picture quality and operation.

Smart Switching (Auto Switching): Automatically switching to select the best resolution.

Tips: This function is related to the hardware configuration of the mobile phone, you can check whether the mobile phone supports this function through the above path, the screen refresh rate supported by different models is different, please refer to the actual support.

The Smart Switching (Auto Switching) switch is removed for ColorOS system versions, and you can select "High Refresh Rate Standard Refresh Rate" according to your needs.

2. If you need to set the screen refresh rate in the game, in addition to setting the screen refresh rate in the mobile phone system, you also need to set it in the game.

2) ColorOS 12 and above: The system settings of the mobile phone and the game assistant setting "high refresh rate" are independent switches. If you enable the "High Refresh Rate Zheng Lixiao" mode in the system settings of the mobile phone, and the performance is set to "Standard Refresh Rate" in the game assistant, the standard refresh rate will be displayed in the game.

If you want to enable the "High Refresh Rate (High Frame Rate)" option in the game, please turn on the ">" High Refresh Rate on the right side of Esports.

Tips: In order to ensure the comprehensive experience of the mobile phone, the mobile phone will intelligently adjust the screen refresh rate to reduce the screen power consumption according to the temperature during use, the adaptability of the app itself, etc., so there are some APP scenarios that cannot reach the highest refresh rate. But please rest assured, if your phone has been set to a high refresh rate and the scene in which the screen is in support of it, the software will intelligently restore the refresh rate, thank you for your understanding and support.

1. The LED screen itself has no refresh rate, because the LED is either always on or off.

2. Problems such as display tailing and flashing eyes are not the problem of LED, but the comprehensive effect of graphics card rate and LED control response rate.

3. The response rate is currently 5 milliseconds and 2 milliseconds, which is equivalent to 200Hz and 500Hz deviation, such as the display rate of 60 sheets per second, because of the response rate deviation, it will be reduced to 13 600 seconds = 46Hz, which will make you feel the flicker, and you can avoid this problem by increasing the speed of the graphics card.

4. Some manufacturers have promoted the concept of LED refresh rate. In fact, he can both praise his own product and avoid the actual problem that he uses a very ordinary monitor with 5 milliseconds. Because he used a response of only 5 milliseconds, plus some deviations, he could only advertise that he was using a 130Hz monitor.

It's a neutral indicator, nothing remarkable.

5. Some manufacturers may have an advantage, he can make up for 3 problems. Manufacturers will never only publicize this advantage, but after publicizing the advantage, they will exaggerate the role of the three issues by independently publicizing them.

The ROG Phone 3 features an inch AMOLED display with a 144Hz top-of-the-line refresh rate and 1ms touch response.

The phone's high refresh rate is useful. In fact, a high refresh rate is very important. Because most users have been adapting to the screen of low brush for a long time,After converting to a high brush, you will feel that the picture is very smooth at first,Then you can't see the difference,Because people's vision has a certain adaptability,And when the high brush cuts to the low brush,The perception will be very obvious,Many users are difficult to use it。

Influencing factors:

1. Hardware. The most important factor affecting the refresh rate is the bandwidth of the display,Now the general 17-inch color display bandwidth is about 100,It can be completely on85Hz,The larger the screen,The larger the bandwidth,19Inch is about 200,21Inch is about 300,Color display of the same brand and size,The higher the bandwidth,The more expensive it is。

The second thing that affects the refresh rate is the graphics card, which also has a refresh rate and resolution available, but in terms of refresh rate, this is now completely negligible.

Because this is mainly aimed at the older generation of graphics cards, now even antique-level TNT2 graphics cards can support 1024*768 resolution to reach 85Hz, 1024*768 is the standard resolution of 17-inch CRT displays. Therefore, the most important thing that affects the refresh rate is the bandwidth of the display.

2. Software. The biggest impact on the refresh rate is the resolution of the screen, for example, the same 17-inch color display, bandwidth108, adjust the resolution to1024*768, up to 85hz, up to 1280*1024, up to 70hz, down to 800*600, but can reach 100hz.

The higher the resolution, the lower the refresh rate will be if the bandwidth remains the same, and the only way to maintain a high refresh rate is to use a high bandwidth, so the bandwidth of large screen displays is very high.

3. Line frequency. Line frequency refers to the number of times that the electron gun in the image tube scans from left to right on the screen per second, the unit is Hz, and the field frequency refers to the number of times the display screen is repeated per second, the unit is Hz, and the line frequency and field frequency are the basic electrical performance of a display.

4. Bandwidth. Bandwidth represents a comprehensive indicator of the display, and it is also an important indicator to measure the quality of a display. Bandwidth refers to the number of images scanned per second, that is, the sum of the number of frequency points displayed on each scan line per unit of time.

The unit is hz,There is a certain calculation method for the bandwidth,When you choose a display,You can calculate the bandwidth according to some parameters,Or calculate some parameters according to the bandwidth。 When the refresh rate of the display is increased a little, its bandwidth will be much higher.

What is the use of a high refresh rate on a mobile phone screen?

The refresh rate refers to the number of times an image on the screen is repeatedly scanned from top to bottom, and the more frames and image information are displayed, the smoother the picture will be. At present, most mobile phones on the market basically use a 60Hz refresh rate screen, which means that the screen can display 60 frames of the screen within 1 second. <

Demo model: iPhone 12 &&& Huawei P40 &&& Xiaomi 11 System version: In actual use, it is reflected in the smoothness of the picture, visual effects, animation transitions, touch feedback and sliding screen feel, and the performance of screens with different refresh rates in these aspects will inevitably be different.

The phone refresh rate is the number of times the phone screen refreshes in one second. Theoretically, the more times this is per unit of time, the more frames and image information can be displayed. The dynamic picture displayed by the mobile phone is actually realized by the rapid switching of the static picture frame by frame.

When the screen switches fast enough, the screen displayed by the phone becomes dynamic in the eyes of the person.

A high refresh rate is equivalent to having more pages when displaying the same animation, thicker and more curved pages make the action between each page more coherent, and when turning quickly, it feels like the animation is smoother, while thinner pages will be a little stuttering when turning due to the lack of coherence between the screens.

Things to keep in mind when buying a mobile phone.

For mobile phone screens, in addition to the screen refresh rate, the screen touch sampling rate is also worth paying attention to. The sampling rate of the mobile phone screen is the frequency of the touch screen to the finger touch to collect the sample in one second. To put it simply, if the screen refresh rate is how many shots per second, then the screen sampling rate is how many times a photographer presses the shutter in a second.

When the screen sampling rate is higher, the mobile phone screen can also give quick feedback, giving people the feeling that the touch is more sensitive, delicate and smooth.

Usually at 60Hz and 120Hz.

The refresh rate of the mobile phone can be viewed by the official ** of the mobile phone brand, and the refresh rate of the mobile phone can be seen in the configuration parameters below the mobile phone model, and the refresh rate of the mobile phone cannot be seen in the mobile phone.

Refresh rate (vertical refresh rate, vertical scan rate) represents the number of new images that a display device can display in one second, measured in hertz (Hz), refresh rate and frame rate are two separate concepts, frame rate indicates the number of new images per second that the device driving the display can produce.

60hz-120hz。

Mobile phone refresh rate users can go to the official mobile phone brand ** to view, you can see the refresh rate of the mobile phone in the configuration parameters of the mobile phone model, it is impossible to see the mobile phone refresh rate in the mobile phone, most of the mobile phones are between 60hz and 120hz.

The higher the refresh rate, the better the stability of the displayed image (picture). The refresh rate will directly determine it**, but since the refresh rate and resolution are mutually restricted, only a display that achieves a high refresh rate at high resolution can be called excellent.

Explain the refresh rate and the effect of a high refresh rate. The increase in the refresh rate on mobile phones is lagging behind compared to computers, and the reason is that **? Is a phone with a high refresh rate any good?
