Interactive Holographic Advertising Fan wholesale for Educational Institutions and Trade Shows Dynamic Learning Tools

The 3D imaging of a holographic fan is essentially a combination of the "persistence of vision" and "precise light control."

By controlling the rotation speed of the blades and the timing of the LED lights' on/off states, discrete light points form a continuous 3D image in the viewer's eye.

When the blades begin to rotate at high speed, the system controls in real time "when to light up and what color to light up" of LEDs at different positions based on preset image content.

For example, to present a "floating apple," the system calculates the "pixel position" of the apple within a 360-degree space. When the blades rotate to the corresponding angle, the LED at that angle is triggered to light up and display a light point of the corresponding color. Because the blades rotate at extremely high speeds, the light point at one angle has not yet disappeared from the viewer's eye before the light point at the next angle is generated. Countless consecutive light points superimpose in space, forming a 3D apple image that is "floating in the air and can be viewed from 360 degrees."

In simple terms, it's like "using a high-speed spinning paintbrush to rapidly paint a picture in the air."

By precisely controlling the rotation rhythm of the "brush" and the color of the "paint" (LED light spots), static light spots are transformed into dynamic 3D images.

Thanks to the optimization of core components and precise control logic, the images presented by the holographic fan possess three major advantages: "clarity, smoothness, and 3D," with visual effects far exceeding traditional flat-panel displays.

The high-density arrangement and high brightness of the micro-LEDs ensure image clarity—even in bright environments (such as shopping malls and showrooms), the images remain clearly visible and will not become blurry due to ambient light interference. Details such as text and patterns are also accurately reproduced; for example, when displaying product parameters, even tiny fonts remain clearly legible, meeting the needs of information transmission.

The high-speed blade rotation and the rapid response of the LEDs result in an extremely high image refresh rate (up to 60 frames per second or more), far exceeding the human eye's perception of image smoothness, eliminating stuttering and ghosting during viewing. Whether it's a static product model or a dynamic character animation (such as waving or rotating), it can be presented smoothly, making it especially suitable for displaying dynamic images and making the 3D effect more vivid.
