Mindify holographic fans use POV (Persistence of Vision) technology. LED beads arranged on rotating blades spin at high speed (hundreds to thousands of RPM). The LEDs flash at precise positions, and the human eye's persistence of vision connects these flashes into a complete 3D image. Because the blades are transparent when spinning, the image appears to float in mid-air — creating a stunning holographic effect. The image size equals the fan blade diameter, so no projection distance is needed.

Three options: (1) Free Cloud Library — access 1000+ ready-made 3D materials optimized for holographic display. (2) Create Your Own — use AI generators, 3ds Max, Cinema 4D, or After Effects. Shoot videos against a black background using a motorized turntable for best results. (3) Custom Content Service — our professional design team creates bespoke 3D animations. Pricing varies from simple logo animations to full product demonstrations with special effects.

Video: MP4, AVI, RMVB. Image/Animation: GIF, JPG, PNG, BMP. For optimal quality, use MP4 files with a black background at the fan's native resolution. Black pixels appear transparent on the display, creating the floating holographic effect. Our team assists with file conversion and optimization at no extra charge. Recommended tools include AI generators, 3ds Max, Cinema 4D, and After Effects.

Standard Series: SD card or mobile App. D/U Series: SD card, App (WiFi), PC software, or real-time phone/PC casting. S/A Series: App, Web portal, PC, or cloud remote management. To connect via App: power on the device → search for the device WiFi on your phone → open the Mindify App → discover and manage your device. S Series supports pre-loaded content and cloud scheduling for remote fleet management.

Yes. D, U, and S Series all support multi-device synchronization and splicing. Arrange fans in horizontal, vertical, arc, or creative formations for large-format 3D displays. A network controller manages up to 50 devices. Splicing formula for 56cm fans: (wall length - 0.56) / 0.4 = number of fans (round up). Accessories include centralized power supplies, aluminum extrusion frames, and sync controllers.

All Mindify products include: 7-day no-questions-asked return (original condition with all accessories), 12-month manufacturer warranty (free repairs under warranty), and lifetime after-sales technical support. For B2B bulk orders, extended warranty terms can be negotiated. Non-human-caused damage during warranty period is repaired free of charge.

When installing outdoors, please take measures to shield the equipment from wind and rain, fix it securely and keep proper drainage. We suggest equipping it with waterproof acrylic or aluminum alloy guards. Feel free to reach out for professional installation instructions.

Standard Series — standard brightness, best for indoor low-light environments. D/U Series — 2500–2800 cd/m², suitable for most indoor commercial spaces including well-lit retail. S Series — 3740–5000 cd/m², designed for bright indoor and outdoor use. S20 (5000 cd/m²) remains visible even in daylight. For best results, position the fan against a dark background to maximize contrast and visual impact.

D/U Series with nylon+fiberglass blades are rated for 24/7 operation. Standard Series can run 10+ hours daily during business hours. Operating temperature range: -10°C to 50°C, humidity <80% RH. All models include thermal management — the high-speed motor generates warmth but operates within safe temperature ranges. For maximum lifespan, operate during business hours with periodic rest.

The effective viewing angle is approximately 178° — the holographic image is clearly visible from nearly all front-facing positions. From directly behind the spinning blades, the display appears transparent (no image). The 3D floating effect is most impressive when viewed head-on at a distance of 1-5 meters, depending on fan size. Larger fans (75cm+) extend the effective viewing distance to 8-10 meters.
