First of all, we need to understand what is the "water ripple" on the LED display? Its scientific name is also known as: "Moiré". When we use a digital camera to shoot a scene, if there is a dense texture, there will often be inexplicable water-like stripes, which is moiré. Simply put, moiré is a manifestation of the beat principle.

 

Why do ripples appear?

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

 

2. The ordinary LED screen will have obvious water ripples when taking pictures with a mobile phone, and the picture looks flickering, while the high-refresh screen will not have water ripples.

 

3. If the requirements are not high or there is no shooting requirement, you can use ordinary brushes. There is not much difference in viewing with the naked eye, the effect is OK, and the price is affordable.

The advantages of choosing a high-refresh LED display

1. Refresh frequency is the speed of screen refresh. The refresh rate is more than 3840 times per second, which we call high refresh rate.

 

2. The high refresh rate is not prone to smearing.

 

3. The effect of taking pictures with mobile phones or cameras, reducing the phenomenon of water ripples, smooth as a mirror.

 

4. The texture of the picture is clear and delicate, the color is vivid, and the restoration degree is high.

 

5. The high-refresh display is more eye-friendly and more comfortable; flickering and shaking will cause visual fatigue, and prolonged viewing will cause eye fatigue. The higher the refresh rate, the less damage to the eyes.

 

6. Conference rooms, command centers, exhibition halls, business halls, smart cities, smart campuses, museums, troops, hospitals, gymnasiums, hotels and other places all use high-brush LED displays, which can highlight the importance of high-brush LED displays.
