The INFiLED HL3978 Series is a transparent rental LED display designed for concerts, music festivals, sporting events and other creative live-production applications.

With 50% transparency, the HL3978 allows light and stage elements to remain visible through the screen while delivering impactful visual content. Its H3.9 mm × V7.8 mm pixel configuration provides a balance between transparency and image performance.

The cabinet supports both concave and convex screen configurations from ?15° to +15°, adjustable in 2.5° increments. It can also be assembled into right-angle structures, giving production teams greater flexibility when creating customised stage and event displays.

Each cabinet measures 1,000 × 500 mm and weighs approximately 7.5 kg, supporting easier transportation and handling. Positioning pins and a pre-lock mechanism help improve cabinet alignment and speed up installation. The HL3978 supports both hanging and stacking installations, with a maximum screen height of up to 9 metres.

For reliable outdoor operation, the series carries an IP65 protection rating and a UL94 V-0 fire-safety rating. Back-shelled modules and metal protection strips help protect the LED surface during transportation, installation and repeated rental use.

The LED modules support both front and rear access and can be removed using a T-shaped wrench. The rear-access control unit features a tool-free design for faster on-site servicing. The HL3978 can also connect with AP Series cabinets to create additional rental display configurations.
