What is hologram 3d fan?

A hologram 3D fan, also known as a holographic fan, is a device that uses LEDs and a spinning blade to create 3D images or videos in mid-air. The fan is made up of several blades that rotate at high speed and create the illusion of a floating image. The image is an optical illusion that is created by the LED lights on the blades being precisely synchronized with the rotation of the fan. The fan can display images and videos in 3D, making it a popular advertising tool for events, trade shows, and retail stores. Hologram 3D fans come in various sizes and shapes, and some are even customizable to display the user's desired image or video. They are often used to showcase products or services in a unique and attention-grabbing way.
