Why Choose High Refresh Rate LED Display?

First of all, we need to understand what is the "water ripple" on the LED display? It's moiré. When we shoot with a digital camera, water-like streaks often appear, which is moiré. Simply put, moiré is a manifestation of the beat principle. Mathematically speaking, when two equal-amplitude sine waves with close frequencies are superimposed, the amplitude of the resulting signal will vary according to the difference between the two frequencies.

Why does moiré appear?

1. There are two types of LED display: high refresh rate and normal refresh rate. The refresh rate of the high refresh rate led display screen can reach 3840Hz/s, and the normal refresh rate is 1920Hz/s. When playing videos and pictures, high refresh rate and normal refresh rate are almost indistinguishable with the naked eye, but they can be distinguished through mobile phones and high-definition cameras.

2. The normal refresh rate led screen will have obvious moiré when taking pictures with the mobile phone, and the screen looks flickering. But the refresh rate led screen will not have moiré.

3. If the requirements are not high or there is no shooting requirements, you can use the normal refresh rate led screen, the effect is ok, and the price is also affordable. The price of high refresh rate and normal refresh is quite different, and the specific choice depends on the specific needs and budget.

Advantages of high refresh rate LED display

1. High refresh rate will not have smear phenomenon.

2. Reduce the appearance of water ripples when taking pictures with mobile phones or cameras.

3. The picture texture is clear and delicate, the color is vivid, and the degree of reduction is high.

4. The high refresh rate led display is more eye-friendly and more comfortable.

5. Widely used in conference rooms, command centers, exhibition halls, business halls, smart cities, smart campuses, museums, troops, hospitals, gymnasiums, hotels and other applications.
