3D holographic fan screen

　　The 3D fan screen is also known as the 3D holographic advertising machine, which is an LED screen device that combines fan rotation and visual persistence factors. In the process of high-speed rotation of fan blades formed by densely arranged lamp beads, a flat display screen is formed by using visual persistence factors. The imaging is made of constantly changing luminous lamp beads. The non-luminous lamp beads and the fan blade frame cannot be recognized by the brain due to high-speed rotation. This effect creates a "space" stereoscopic imaging view. When the content is 3D content, watch The result is 3D. Therefore it is called a 3D fan screen.
