When we talk about the performance of LED displays, the refresh rate is a parameter that cannot be ignored. And the refresh rate plays an important role in LED Displays, especially indoor LED displays and events LED displays.

What is the refresh rate in LED displays?

The Refresh Rate refers to the number of times the LED screen repeatedly displays (scans) the content per second. And it is usually measured and written in Hertz (Hz), like 960Hz, 1920Hz, and 3840Hz and so on. 1920Hz means the content is repeated in 1920 times per second.

The refresh rate is a parameter indicative of the LED displays. And it is also an important indicator to characterize the stability and non-flickering of the LED video wall.

The refresh rate is related to the scan rate and type of IC.

It may be confuse about refresh rate and frame rate.

What is frame rate?

Frame rate is not a parameter in LED display. It is a parameter in videos, movies, games etc. It is familiar with FPS in games. It refers to the number of times the picture information is updated per second. Due to the visual dwell effect of human eyes, if the dwell time of the two pictures is shortened, the coherence of the video will be better. The frame rate is generally 24Hz, 25Hz, 30Hz, 60Hz, 75Hz etc. The higher the frame rate, the better the continuity of the changed image. Normally the frame rate in videos are 24Hz to 30Hz.

How does the refresh rate affect the LED displays performance?

The more times the LED screen is refreshed, the smoother the images are in terms of motion rendering and flicker reduction, the better the stability of the images and video shown in LED displays.

Why do we recommend higher refresh rate for indoor LED displays and events LED displays?

1. More comfortable for watching.

With higher refresh rate, we can have a better viewing experience without uncomfortable eyes while watching for a long time. It is eye-friendly for indoor close watching.

2. Reduce the phenomenon of water ripples.

When you use your phone or DV device to record videos/images from the LED display, you will notice obvious water ripples in your phone or DV because it is low refresh rate. With higher refresh rate, it will reduce the phenomenon of water ripples and it will be as smooth as a mirror.

We cannot see water ripples from our eyes. This only happens when using phone or DV/DC to shoot photos or videos from LED displays.

3. Clear, delicate image texture and vivid colors.

It will have better image and color performance with higher refresh rate.

4. Better visual experience.

Higher refresh rate will reduce flickering and shaking phenomenon in LED displays, and provide a better visual experience.
