A fan hologram and a 3D hologram fan are two different types of holographic displays, and they work in slightly different ways. A fan hologram, also known as a holographic fan or a holographic projector, is a type of display that uses a spinning fan with LED lights to create the illusion of a three-dimensional image. The fan spins at a high speed, and as it rotates, the LED lights on the blades illuminate different areas, creating the illusion of a 3D object floating in the air. Fan holograms are typically small and can display simple, low-resolution images. On the other hand, a 3D hologram fan, also known as a holographic 3D fan, is a type of display that uses a spinning LED bar to create a more high-resolution 3D image. The LED bar is mounted on a motorized base and spins at a high speed, while the image is projected onto the bar from multiple angles. This creates the illusion of a more detailed, lifelike 3D image. In summary, a fan hologram and a 3D hologram fan both create the illusion of a 3D image using spinning LED lights, but a 3D hologram fan is typically larger and more high-resolution than a fan hologram. https://www.superbholo.com/3d-hologram-fan-sh-65/
