What does refresh rate mean in LED displays and transparent LED screens?

The refresh rate of both LED displays and LED transparent screens represents the speed of the screen. The faster the refresh rate, the higher the screen display frequency, which means fewer ripples, lines, and shadows left by our photos.

Meanwhile, LED screens require high refresh rates, which necessitates high-refresh-rate ICs and a high number of scans. Static scanning is the most stable and won't leave lines or ripples when photographed. Low-refresh-rate screens, on the other hand, will leave shadows or ripples. This kind of slow-refresh-rate information can only be captured by high-definition mobile phones or cameras and is usually imperceptible to the naked eye.
