LED display is a kind of using leds in sequence of new imaging electronic equipment, can display the change number, text, graphics, image ;Not only can be used in indoor environment also can be used in outdoor environment, with a projector, TV wall, LCD display screen the incomparable a bit . Due to its high brightness, wide viewing Angle, long life and other characteristics, is being widely should be in outdoor advertising and other products .Stable rotating carrier like this design by installing multiple columns LED light-emitting devices realize rotary display function, according to the principle of visual lag effect, will be the columns when still luminous
