Description

technical field

[0001] The invention relates to an electronic display screen, in particular to a display screen which utilizes the persistence of vision effect of human eyes to generate continuous images for discontinuous light. Background technique

[0002] As a new type of display material, LED dot matrix has developed rapidly in recent years and has a good market prospect. Among them, LED large-screen displays are widely used in fields such as industry, transportation, commercial advertisements, press releases, sports competitions, and electronic scene simulation. However, the existing LED large screen requires a large number of LEDs and driver chips, and the control is complicated, which makes the display screen expensive and difficult to operate.

[0003] The Chinese utility model patent No. 03257185.2 discloses a "multi-layer array light source mobile imaging display device", which is characterized in that an electronic control circuit is installed on a displaceable s...
