What is the Moire Effect on LED Screens?

The Moire effect is a visual distortion phenomenon that occurs when two similar or slightly different patterns overlap or superimpose, resulting in a strange pattern on the screen. This phenomenon can cause irregular streaks in the image or video displayed on your LED screen. In simple terms, when the Moire effect occurs, unusual streaks appear on the display that do not match the original display content.

"Moire" is French for "wavy" or "hazy," which fits the undulating streaks that the effect typically produces. These patterns can interfere with the viewer's visual experience, creating a confusing or even uncomfortable visual experience. They can affect the clarity of the entire image, text, or video, or interfere with the presentation of legitimate parts of it.

For example, if you are watching an event or your favorite TV show and a distorted rainbow-like pattern appears on the screen that does not match the original display content, this may be the Moire effect on your LED screen.

Sometimes, the Moire effect can appear on a large scale, making it difficult to recognize the original display content. Next, we will discuss the various factors that cause the Moire effect, the corresponding solutions, and how to prevent it from happening again.
