Q1:What is a static screen, what is to scan screen, what is the difference between the two?

Scanning screen refers to the light like a scan on the led display, is the advantage of the characteristics of the human eye of persistence of vision, in a short time period will be led display all light respectively.
The difference between the two: because the LED display is driven by duty ratios, which makes the brightness of the LED display has a lot to do with the light of time cycle. So, in the same light tube with the same brightness, static screen is higher than scanning the brightness of the screen, so commonly used static screen need high brightness in the outdoor show, the scanning screen commonly used in the interior of brightness demand is not high, driven to save cost.
