How to choose the appropriate refresh rate for an LED screen?
2020-08-17210
You may come across the term “refresh rate” when you check the parameters of a LED display and sometimes meet the phrase “moiré pattern” when you read the articles about video walls. But what exactly does refresh rate mean? How much do we need it? What determines the performance of the refresh rate of an LED wall? No worries, you will find the answers below.
What is refresh rate for LED screens?
The refresh rate of an LED display refers to the number of times per second that an image is drawn on an LED display and is usually measured in hertz (Hz).
Generally speaking, a high-performance LED display requires a refresh rate of 3,000 Hz or above. Higher refresh rate will lead to more stable broadcasting and less flicker.
If the refresh rate is insufficient, it will not only cause flickering to discomfort our eyes, but also generate scanning lines during shooting through cameras.
How much is the refresh rate needed for an LED screen?
To make it simple, we can divide it into two application scenarios. One is for daily use, for example, document presentation. To meet the direct-view ease, we recommend a refresh rate of 1920Hz and sometimes higher. The other is for professional use such as photography, filming, live streaming, or close-ups applied in industries including broadcasting, education and sports, which asks for 3840Hz at minimum to achieve a scanning-line-free visual effect.

What’s the difference between scanning line and moiré pattern? It’s worth mentioning that the scanning line is not the same as the moiré pattern. The moiré pattern is the odd stripes and patterns that appear on taken images due to the high-frequency interference on the photosensitive elements of shooting equipment like digital cameras. Its appearance lies on the shooting devices, the shooting distance and the shooting angle. The scanning line is the black stripes captured when the LED screen refresh rate cannot catch up with the camera's shutter speed. Hence, scanning lines are closely related to the performance of the LED screens.
How to improve the refresh rate of LED walls?
In order to avoid the occurrence of scanning lines during shooting, high refresh rate is crucial, which is decided by the IC (Integrated Circuit Chip) of the LED display. Currently, LianTronics fine-pitch LED displays adopt the latest PWM technology to effectively improve the refresh rate, and have been widely applied in massive TV studios and stadiums globally.
