01Choosing the Right System

What is the difference between an LED dome screen and a spherical LED display?

An LED dome screen (inner dome) is installed inside a hemispherical building or ceiling and is viewed from below and around — it is the screen of choice for immersive cinemas, flight theaters and planetariums. A spherical LED display (ball screen) is a self-supporting sphere, usually outdoors or in an atrium, viewed from all directions — it serves science museums, commercial plazas and city landmarks as an iconic media facade.

Luminatii manufactures both product lines, engineered as separate systems. See our LED dome screens and spherical LED displays pages for details.

Should I choose an LED dome screen or a projection dome?

Projection domes win on initial price for very large diameters, but an LED dome delivers far higher brightness (usable with ambient light), true 8K-class sharpness with no edge blending, 10,000:1 contrast, no projector lamp or filter maintenance, and a 10+ year service life.

For commercial flight theaters and attractions that run shows all day, every day, LED is the lower total-cost choice; projection still suits temporary events and extreme budgets.

Do you deliver the steel structure together with the screen?

Yes. Steel structure + screen body + playback control system is our standard one-package delivery. The steel is pre-engineered against your building drawings, factory-fabricated, and installed by our crew or under our supervision, so screen curvature and structure are guaranteed to match.

Can you build spherical LED displays for outdoor landmarks?

Yes. Outdoor ball screens from 2 m to 26 m diameter have been delivered, including a 26 m full outer-sphere display in the Philippines and a 6 m-diameter landmark sphere in Hezheng, Gansu. Outdoor versions are engineered with IP65-rated waterproof modules, UV-resistant surface treatment and wind-load structural calculations for the site.

02Sizes, Customization & Performance

What sizes of LED dome screens and spherical displays can you manufacture?

LED dome screens: 5 m to 60 m in diameter delivered, including Asia's largest 5,300 m² dome on Kongtong Island. Spherical LED displays: 2 m to 26 m in diameter delivered.

Both ranges are fully custom — any diameter is engineered panel-by-panel to your site. There is no catalogue limit and no upper size cap: tell us the diameter you need and we build it.

Can you build a dome or sphere larger or smaller than your standard range?

Yes. Every project is modeled individually. Send us the building drawings and we will return a structural and optical feasibility proposal — panels are curved and numbered per position, so diameter and coverage angle are free parameters, not fixed options.

Which pixel pitch should I choose for an LED dome?

It depends on viewing distance and content. Typical choices: P1.8–P1.9 for close-viewing domes under 10 m, P2–P2.5 for 15–25 m immersive domes, P3–P4 for very large domes where viewers are tens of meters away.

We select the pitch together with you against seat layout, minimum viewing distance and budget.

How bright is the screen — can it be used with lights on?

Our indoor dome platform delivers 1,200 nit with brightness uniformity deviation ≤ 5%, bright enough for pre-show lighting and walk-in operation. Outdoor spherical displays are configured at higher brightness for direct daylight. Brightness is adjustable scene by scene through the control system.

Can the dome be openable or kinetic?

Yes. Our 60 m Kongtong Island dome — Asia's largest at 5,300 m² — is a mechanically dynamic inner dome with openable sections. Kinematic design is one of our specializations; tell us the movement concept and we will engineer the drive, safety and sealing systems.

Is the dome acoustically transparent?

Yes, on request. Our sound-transparent dome uses 50% perforation with sound loss under 5% and audio-visual sync error below 0.02 s, so speakers can be hidden behind the screen — essential for flight theaters and immersive cinemas.

03Site, Structure & Installation

What building conditions does an LED dome need?

Three basics: a structure that can carry the screen and steel (we provide exact load data), sufficient interior volume for the chosen diameter and viewing angle, and standard power plus network access.

Send us the architectural drawings and we will confirm feasibility, loads and mounting details free of charge.

How long does installation take?

Typical domes are installed in 15–45 days on site depending on diameter and height access; mega projects are phased — the 60 m Kongtong dome was engineered and installed on site in about 180 days. Spheres from 2–10 m are usually up in a few days.

Do you send engineers to install and commission on site?

Yes. For dome projects, on-site installation guidance, commissioning and operator training are included in the standard scope. For spherical displays, we can deliver with supervised installation or send a full crew, depending on your local capability.

Can you work with our local contractor and architect?

Yes, and we do it routinely. We provide the screen-side engineering (structure loads, panel layout, cable routing, control room layout) and coordinate with your GC and AV integrator throughout. Boundary drawings are issued in DWG/PDF for the design team.

04Content, Control & Integration

Do you supply the show content for the dome or sphere?

We supply the content mapping and playback system calibrated to your exact panel layout, plus basic commissioning content. For original show films we cooperate with established dome content studios and manage the delivery interface, or we hand over full technical specifications to a content partner of your choice.

Which media servers and control platforms do you support?

Our playback system integrates with the major show-control and media-server platforms used in themed entertainment, and with flight-ride motion platforms from the leading ride suppliers. Tell us which show-control ecosystem your park uses and we will confirm the interface before contract.

Can you integrate the screen with a flight-ride motion platform?

Yes — integration with major flight-ride and show-control platforms is standard for us, including genlock, motion-to-picture latency tuning and show-trigger handshaking. Several of our delivered domes operate as flight theaters today.

05Delivery, Certification & Export

What is the typical lead time from order to delivery?

Typical domes: 45–90 days after drawings are confirmed. Mega projects (60 m-diameter class) are engineered in phases — around 180 days on site. Spherical displays: roughly 30–60 days depending on diameter and customization. Exact schedules are fixed in the contract.

Which certifications do your products carry for export?

CE (EMC + LVD), FCC, UL/IEC 62368-1 for product safety, plus ISO 9001 / 14001 / 45001 for the factory and CCC for the Chinese market. We provide full export documentation support including packing lists, certificates of origin and test reports.

06Commercial, Warranty & Support

How is an LED dome or sphere project priced?

Pricing is driven by diameter, coverage angle, pixel pitch, structure scope and customization (openable sections, sound transparency, outdoor rating).

Send the drawings and requirements, and you receive an itemized quotation — screen body, steel, control, installation and training listed separately — within one business day.

What are your payment terms, warranty and after-sales support?

Standard payment is 30% deposit / 70% before shipment, adjustable for large projects. Warranty covers the standard term with lifetime remote support; on-site commissioning and operator training are included for dome projects. Spare-part kits ship with every system and consumable modules are stocked for long-term supply.
