Have you ever noticed flickering or stripes appearing on an LED screen while filming events, stage performances, or live streams, as if the screen is “shaking”?
Why does the image appear normal to the human eye, but cause problems when filmed by a camera? This is a common frustration for many novice photographers and event planners.
In fact, the root cause isn’t just the camera or screen quality, but involves multiple factors, including the LED screen’s working principle, power frequency, refresh rate, and environmental conditions.
