Viewing geometry
Audience eye points, field of view, nearest viewing distance, dome centre, tilt and crop define a buildable pixel surface.
Current development focus
An LED dome starts with the room, not the module
NJ Endure applies compound-curvature geometry, supporting-structure and site-installation experience to inward-facing LED domes. Our present scope is feasibility, proof-of-concept work, carrier and interface engineering, and integration with qualified display partners.
Development status · feasibility, testing and partner integration — not presented as a mature NJ-delivered LED product line
Why the system boundary matters
The screen behind the image is a building system
Large LED domes add distributed heat, power, data, service access and substantial weight to a precision display surface. These disciplines must be resolved together before a pixel pitch or cabinet price becomes meaningful.
Carrier precision
A globally accurate sphere needs controlled cumulative error, adjustable interfaces and measured installation—not forced alignment on site.
Heat, power & data
Electrical zoning, airflow, controls and fault isolation are planned as part of the dome and building services.
Access & acoustic path
Modules, power supplies and loudspeakers must remain reachable without compromising the image, sound field or fall protection.
Display-route decision
Projection and LED solve different venue problems
We assess both routes against the experience, building and operating model. LED is not an automatic upgrade, and projection is not a legacy default.
| Decision area | Perforated aluminium projection | Inward-facing LED |
|---|---|---|
| Best fit | Large areas, controlled light, established fulldome content and capital efficiency. | Premium contrast, multi-use venues, high brightness and reduced projector obstruction. |
| Facility impact | Relatively light screen; heat is concentrated around projection equipment. | Distributed power, heat, data and materially higher structural/service demands. |
| Audio | Mature perforated surface options for loudspeakers behind the image. | Requires an acoustically transparent module/cabinet architecture and installed-system testing. |
| Maintenance | Surface cleaning, local panel repair and projector maintenance. | Large populations of modules, power supplies and controls require access, spares and recalibration. |
| NJ scope | Established project-specific surface, structure, installation and acceptance package. | Feasibility, carrier/interface engineering, testing and partner-led integration. |

Engineering scope
Six workstreams before site installation
Each workstream is version-controlled and assigned to NJ, the display partner, the AV team, the building engineer or the venue operator through a clear responsibility matrix.
Geometry & pixel study
Eye-point analysis, field of view, dome crop, target pitch, content resolution and minimum viewing distance.
Structure & tolerance
Load paths, adjustable nodes, thermal movement, installation datums and survey/point-cloud acceptance.
Thermal & electrical
Power modes, heat balance, airflow, zoning, grounding, protection, redundancy and monitoring.
Acoustic coordination
Open area, insertion-loss data, loudspeaker distance and service access behind the image.
Maintenance design
Front/rear service strategy, ladders or catwalks, fall protection, spare-part routes and digital asset numbering.
Control & acceptance
Pixel mapping, sync, colour/brightness calibration, burn-in, FAT/SAT and failure-recovery tests.
Stage-gated development
Evidence before a product claim
A project advances only when the geometry, partner architecture and measured prototype support the next commitment.
Feasibility
Compare LED and projection; define the display envelope, loads, utilities and budget corridor.
Partner architecture
Freeze module, cabinet, control and IP responsibilities with a qualified display provider.
Full-scale segment
Build an equivalent-curvature section and measure geometry, heat, sound and maintainability.
Detailed engineering
Release coordinated structure, electrical, access, installation and acceptance documents.
FAT, SAT & handover
Pre-assemble, burn in, install, survey, commission and hand over traceable records and spares.
