1. Introduction
Nowadays, with the rapid development of technology, the display screen field is constantly evolving and innovating. Sphere LED display screen has become the focus of attention due to its unique design and excellent performance. It has a distinctive appearance, powerful functions, and a wide range of application scenarios. Let’s explore its appearance structure, unique visual effects, and applicable scenarios together. Next, we will deeply discuss the important factors to be considered when purchasing spherical LED display. If you are interested in sphere LED display, then read on.
2. Four factors influence the purchase of sphere LED display
2.1 Display effect of spherical LED display
Resolution
Resolution determines the clarity of the image. For sphere LED display, its pixel pitch (P value) should be considered. A smaller pixel pitch means a higher resolution and can present more delicate images and texts. For example, in some high-end LED sphere display, the pixel pitch can reach P2 (that is, the distance between two pixel beads is 2mm) or even smaller, which is suitable for occasions with close viewing distances, such as small indoor spherical display screens. For large outdoor spherical screens, the pixel pitch can be appropriately relaxed, such as around P6 – P10.
Brightness and Contrast
Brightness refers to the intensity of the display screen’s illumination. Outdoor sphere LED display requires higher brightness to ensure that the screen content remains clearly visible in strong light environments such as direct sunlight. Generally, the brightness requirement for outdoor screens is between 2000 – 7000 nits. Contrast is the ratio of the brightness of the brightest and darkest areas of the display screen. High contrast can make the image colors more vivid and the black and white more distinct. Good contrast can enhance the layering of the picture. For example, on a sphere screen playing sports events or stage performances, high contrast can enable the audience to better distinguish the details in the scene.
Color Reproduction
This relates to whether the sphere LED screen can accurately present the colors of the original image. A high-quality sphere LED display should be able to display rich colors with relatively small color deviations. For example, when displaying artworks or advertisements of high-end brands, accurate color reproduction can present the works or products to the audience in the most realistic manner. Generally, the color gamut is used to measure the color reproduction degree. For example, a display with an NTSC color gamut reaching 100% – 120% has relatively excellent color performance.
2.2 Size and Shape of Spherical LED Display
Diameter Size
The diameter of the sphere LED display depends on the usage scenario and requirements. A small sphere LED display may have a diameter of only a few tens of centimeters and is used in scenarios such as indoor decoration and small exhibitions. While a large outdoor spherical LED display can reach several meters in diameter, for example, it is used in large stadiums to play event replays or advertisements. When choosing the diameter, factors such as the size of the installation space and the viewing distance should be considered. For example, in a small science and technology museum exhibition hall, a sphere LED display with a diameter of 1 – 2 meters may be only needed to display popular science videos.
Arc and Precision
Since it is spherical, the accuracy of its arc has a great impact on the display effect. A high-precision arc design can ensure the normal display of the image on the spherical surface without image distortion and other situations. An advanced manufacturing process LED sphere screen can control the arc error within a very small range, ensuring that each pixel can be accurately positioned on the spherical surface, achieving seamless splicing and providing a good visual experience.
2.3 Installation and Maintainence
The installation methods of spherical LED display include hoisting, which is suitable for large outdoor or indoor high-space venues; pedestal installation, commonly used for small indoor screens with good stability; and embedded installation, able to integrate with the environment. When choosing, factors such as the bearing capacity of the building structure, installation space, and cost should be considered. Its maintenance convenience is also very important. Designs such as easy disassembly and replacement of lamp beads and modular design can reduce costs and maintenance time. The design of maintenance channels is particularly crucial for large outdoor screens. For details, you can view “Sphere LED Display Installation and Maintenance Full Guide“.
2.4 Control System
Signal Transmission Stability
Stable signal transmission is the foundation for ensuring the normal operation of the display screen. For spherical LED display, due to its special shape and structure, signal transmission may be subject to certain interferences. You need to consider high-quality signal transmission lines and advanced transmission protocols, such as fiber optic transmission and Gigabit Ethernet transmission protocols, which can ensure that the signal can be accurately transmitted to each pixel point. For example, for the sphere LED display used at some large event sites, by transmitting signals through fiber optics, electromagnetic interference can be avoided, ensuring the smooth playback of videos and images.
Control Software Functions
The control software should have rich functions, such as video playback, image switching, brightness and color adjustment, etc. Meanwhile, it should also support various formats of media files to facilitate users’ content updates. Some advanced control software can also achieve multi-screen linkage, combining spherical LED display with other surrounding display screens for unified content display and control. For example, during stage performances, through the control software, sphere LED display can be made to play relevant video content synchronously with the stage background LED screen, creating a shocking visual effect.
3. The Cost of Purchasing Sphere LED Display
Small spherical LED display
Usually with a diameter of less than 1 meter, it is suitable for small indoor displays, store decorations and other scenarios. If the pixel pitch is relatively large (such as P5 and above) and the configuration is relatively simple, the price may be between 500 and 2000 US dollars.
For a small spherical LED display with a smaller pixel pitch (such as P2-P4), better display effect and higher quality, the price may be around 2000 to 5000 US dollars.
Medium spherical LED display
The diameter is generally between 1 meter and 3 meters, and it is often used in medium-sized conference rooms, science and technology museums, shopping mall atriums and other places. The price of a medium-sized spherical LED display with a pixel pitch of P3-P5 is about 5000 to 15000 US dollars.
For a medium-sized spherical LED display with a smaller pixel pitch, higher brightness and better quality, the price may be between 15000 and 30000 US dollars.
Large spherical LED display
With a diameter of more than 3 meters, it is mainly used in large stadiums, outdoor advertising, large theme parks and other scenarios. This kind of large spherical LED display has a relatively high price. For those with a pixel pitch of P5 and above, the price may be between 30000 and 100000 US dollars or even higher.
If there are higher requirements for display effect, protection level, refresh rate, etc., or if special functions need to be customized, the price will further increase. It should be noted that the above price ranges are for reference only, and the actual price may vary due to factors such as market supply and demand, manufacturers, and specific configurations.
| Type | Diameter | Pixel Pitch | Applications | Quality | Price Range (USD) |
| Small | Less than 1m | P5+ | Small indoor, decor | Basic | 500 – 2,000 |
| P2 – P4 | Small indoor, decor | High | 2,000 – 5,000 | ||
| Medium | 1m – 3m | P3 – P5 | Conference, museums, malls | Basic | 5,000 – 15,000 |
