The driving component 2 is used to drive the fan blade component 3 to rotate. A display circuit board 4 is installed on the front side of the fan blade component 3, and a plurality of LED lamp beads are installed on the front side of the display circuit board 4. The display circuit board 4 controls the light-emitting sequence of the LED lamp beads, thereby realizing the 3D display function.
