3D holographic advertising machine, this is a combination of fan rotation + LED light bar display, using the principle of human eye persistence to form an aerial phantom of graphics, animation and video.

When imaging, all LED lights emit light, and the surrounding shell is dark and does not emit light. In this way, when the 3D holographic advertising machine is operated, the human eye will only receive the light staying, and the dark color and no light will be too fast to fail. Recognized by the brain, the display effect will only stay on the light displayed by the LED light, so that the effect of aerial imaging is realized, and then a 3D floating image is presented.

The working principle of the 3D holographic advertising machine is mainly to use the persistence factor of human vision (POV technology), through one or several columns of LEDs densely arranged and then rotating imaging. In detail, the visual effect produced by light on the retina will remain for a period of time after the light stops working.
