For small retail stores, shopping malls, and indoor showrooms, a medium-sized hologram fan (50 cm-65 cm) is usually sufficient to create visually stunning 3D animations without taking up excessive space. However, for corporate events, trade fairs, exhibitions, concerts, and product launches, larger holographic fans (75 cm-100 cm) are recommended, as they ensure that animations remain clear, bright, and visible even from a distance. Some of the latest 3D LED holographic fans also come equipped with Wi-Fi and cloud connectivity, allowing businesses to remotely control and update their advertising content via smartphones, tablets, or computers. This is particularly useful for businesses running multiple advertising campaigns or those needing to modify promotional content dynamically, as it enables seamless content updates without the need for manual intervention.
