Aura 42cm HD 3D Holographic Display (224-LED, Wi‑Fi)
The Intent
Purpose-built aerial non-screen display for retail, events, exhibitions and branded installations. The Aura 42cm unit uses a rotating LED array to create a persistence-of-vision (POV) aerial image — delivering attention-grabbing 3D visuals without projection surfaces. Designed for content-driven advertising, product showcases, and experiential activations where a compact, high-impact holographic effect is required.

The Benefit
Delivers bright, high-definition floating visuals that cut through ambient environments to attract attention and improve recall. The dense 224-LED array produces lifelike color and clarity suitable for dim booths and brighter retail spaces alike. Wi‑Fi + app-driven content management enables rapid content swaps and scheduled loop playback from a smartphone or PC. Bluetooth audio option augments visual content for immersive presentations and promos.
Operational Assurance
Installation is straightforward: detachable blades for safe transport and compact mounting, with clear mounting points for trade-show stands or retail fixtures. Routine maintenance is minimal; replaceable LED modules and durable ABS/PC housing help ensure long operational life. The unit accepts BIN-formatted play files and supports multiple video loop playback for unattended operation.
Safety & handling notes: rotating blades necessitate secure mounting and a safety perimeter; follow local electrical and mounting codes. For custom content or format conversion, use the device app or convert assets to the device BIN format before upload.
Installation & Assets
Quick checklist for deployment: detach blades for transport; mount to stable fixture; connect to AC 100–240 V; pair via Wi‑Fi and upload BIN content via the app. Units ship with a large preloaded library (~700 clips) spanning holidays, product animations, logos and category-specific visuals; manufacturer support available for custom video creation.
