Sometimes when we buy a P2 LED screen, we will hear some LED manufacturers mention high refresh and normal refresh, and will explain to customers that the price of high refresh will be more expensive. So what are high refresh and normal refresh? Let’s take a look at the difference.
Nowadays, many customers have very high requirements for the picture quality of the screen, so some LED display manufacturers will also meet the needs of customers, and use high refresh as the selling point of the LED display. Speaking of which, there is still a big difference between the two.
The difference between high refresh and normal refresh
High refresh rate for smoother screen quality
The refresh rate of the LED display is how many times the screen updates the display information per second. When playing dynamic video, the switching frame number will be faster and the fluency will be higher, so the screen will get faster response speed. In fact, it’s not just video, it’s the same as the mobile games we often play.
Games have high requirements on the GPU and high requirements on the screen. In the gaming field, a frame rate of 60fps is the basic requirement for smooth gaming. The pictures in the game are all static frames rendered by the game engine. When playing games, the frame rate and delay are generally checked. The higher the frame rate, the lower the delay, and the response is faster for competitive games, especially during battles. You can win, because the reaction time is slow but you lose, and it is easy to think about the game mentality.
The game needs high fps, but it also needs the screen to cooperate. If the graphics card can output a frame rate of 90fps, and the display screen is only 60Hz, 30 frames of the game screen will be discarded as invalid frames in 1 second, which is equivalent to wasting the gaming power of the graphics card. And if the display also has 90Hz, the game will appear smoother.
Therefore, from the point of view of playing games, we can easily find that Hertz has a great influence on the display of the screen, especially in the case of requiring the fineness of the picture quality, the gap is even more obvious.
Although the high refresh LED display is better, it will also bring some small problems that need to be measured by customers.
High refresh rate screens consume more power
Although the refresh rate can make the viewing screen or playing games smoother, it will also increase the power consumption. When setting a higher refresh rate, the power consumption will also be higher, and the demand on the battery and charging will also increase.
This also means that the battery that can play games for 4 hours can only be played for 3.6 hours if you use a high screen refresh rate. Of course, this has no obvious effect on the LED display, because the LED display needs to be plugged in for continuous power supply, but the power consumption will increase.
High refresh rate screen life will be reduced
For screens with high refresh rates, because more screens are displayed every 1 second, the service life will be relatively reduced under the same conditions.
However, we don’t need to worry too much. Because the above is the same situation. In fact, the materials used for high-brush screens and ordinary screens are different for LED displays. Ordinary refreshed LED displays generally use copper wires as the medium, while high-definition refreshes generally use copper wires as the medium.
The LED display will use gold wire as the medium, so the price of the high-brush LED display will be much higher than that of the ordinary refresh. The lifespan will not only be lower than that of the ordinary refresh, but will be longer than that of the ordinary refreshed LED display. longer time.
To sum up briefly, high refresh rate screens do have a great impact on the user’s experience of using the phone in some scenarios. If the gap in visual effects is described in words, the higher the refresh rate, the more “delicate” the display effect. But this distinction is also limited to “certain scenarios”.
As long as the Hertz of the picture exceeds 30, the human eye cannot perceive the difference. Therefore, the high-resolution refresh rate and the ordinary refresh rate, just by looking at it with the naked eye, will not make any difference.
