LED-Kugelbildschirmtypen: Vollkugel oder Halbkugel?

The first choice is where the audience stands relative to the image. A full sphere presents a globe from multiple sides; an outward hemisphere presents a convex surface; an inward hemisphere creates a concave viewing zone. Mounting and indoor or outdoor use are separate configuration decisions.

Compare the three display forms

Form Bildoberfläche Nützliche Ausgangsbedingung
Vollkugel Outward-facing globe Visitors approach and move around the object from several sides.
Äußere Hemisphäre Convex half-sphere The installation presents a curved object from an open front or approach route.
Innere Hemisphäre Concave half-sphere Visitors look into an open curved image from a planned viewing zone.

Das sphere and hemisphere product range provides the configuration route. Shape describes the display surface; hanging, floor mounting and architectural integration describe how that surface is installed.

If the desired form is shallower than a half-sphere, specify its opening and depth. Calling every curved segment a hemisphere can hide a significant difference in the required LED layout and frame.

Choose from the audience route

Choose a full sphere when the globe itself is the visual feature and visitors encounter it from multiple directions. Decide where key messages should appear as people move; an image visible from one position does not make every part of the sphere visible at once.

Consider an outward hemisphere when the architecture provides one main approach and a complete rear display surface would serve little purpose. Consider an inward hemisphere when the image should occupy a concave zone that the audience looks into.

An inward-facing curved display with an open viewing side
The open side determines how the audience approaches an inward-facing display.

For the half-sphere options, the hemisphere planning guide covers opening dimensions, depth and viewing side in more detail.

Treat mounting and maintenance as a separate choice

A suspended display needs an agreed support and handling design. A floor-mounted assembly needs a suitable base, clearances and cable routes. An integrated wall or ceiling design needs access for assembly and maintenance after the surrounding finishes are complete.

Curved display assemblies awaiting further factory work
The frame and assembly plan follow the selected shape and installation interfaces.

Ask for the proposed assembly envelope and supporting connections. Plan the delivery route around actual package dimensions and weights. The visible sphere diameter alone cannot establish whether the assembled unit fits a doorway or how it should be lifted.

Select the configuration for the environment

Indoor or outdoor use is another configuration decision, separate from full sphere or hemisphere geometry. State exposure, ambient light, operating conditions and maintenance access. Confirm the proposed hardware for that environment rather than treating a display shape as proof of suitability.

Then choose diameter and pitch around the viewing positions and content detail. The sphere size guide lists confirmed full-sphere diameter and pitch combinations; a custom segment requires its own geometry review.

Prepare the shape and configuration request

Send a site photograph or drawing with the audience route, approximate size, viewing side and proposed mounting position. Add the environment, sample content and delivery destination. If two shapes remain possible, describe the intended experience so they can be compared against the same requirements.

The complete display includes the control system. Other equipment, accessories and services are determined by the project configuration and formal quotation. Request a sphere or hemisphere proposal with the selected form or the two options you want to compare.

FAQ
What are the main types of LED sphere screens?
The main forms considered here are a full outward-facing sphere, an outward-facing hemisphere and an inward-facing hemisphere. They differ in the curved surface presented to the audience and the available viewing zone. Mounting method, environment, diameter and pixel pitch are separate configuration decisions. Start with the audience route before selecting those technical and installation details.
When should I choose a full sphere rather than a hemisphere?
A full sphere suits a globe that visitors approach from several sides, especially when the object itself is the visual focus. A hemisphere can suit a more defined approach or an open inward viewing zone. Compare the audience route, architectural space and content placement first, then check the support, access and configuration required by each option.
Is a dome the same as a hemisphere LED screen?
A hemisphere describes a half-sphere geometry, while dome is often used more broadly for a curved installation. An inward-facing LED dome may use a hemisphere or a shallower curved segment. Specify the opening diameter, depth, tilt and viewing side so the supplier can determine the intended shape rather than infer it from the name alone.
Are hanging and floor-mounted spheres different display types?
Hanging and floor-mounted describe installation methods rather than different image geometries. Either method requires a suitable frame, support arrangement, cable routing and maintenance access for the selected display. Confirm assembly dimensions and loads from the project design. Handling equipment and site installation responsibilities should be agreed separately in the project configuration and formal quotation before work begins.
Can every sphere type be used outdoors?
Outdoor suitability must be confirmed for the proposed configuration and site conditions. Shape alone does not establish it. Provide the exposure, ambient light, operating conditions and service access so the supplier can select and document suitable hardware. An indoor configuration or an example photograph should not be used as the specification for an outdoor installation.
What should I send when I have not chosen the shape?
Send a site image or sketch, the audience route, approximate available dimensions and the intended content. Indicate whether visitors should walk around an object or look into a curved viewing zone. Include the environment, mounting position and destination. Those inputs allow full-sphere and hemisphere options to be compared on the same project requirements before detailed configuration.
