Refresh Rate of LED Display
Refresh rate refers to the number of times the LED display is displayed completely in seconds. The unit is Hz. If the refresh rate is too low, the human eye will see jitter in the LED display. When the camera shoots, there will be a scan line. The average human eye has a refresh rate of 300Hz or more. That is, as long as the refresh rate exceeds 300Hz, most people will not feel jittery when viewing the LED display with the naked eye. If you use a camera to shoot, the minimum requirements are generally based on different settings of different cameras. Above 600Hz can not capture the scan line. A high refresh can improve the brightness and vividness of the display. It can be detected with a digital camera. If it is a high refresh, the picture taken by the camera is very clear, there is no snow point and scan lines. This indicator is particularly important at lease screens and television broadcasts.
