Spherical LED displays are a creative display device that breaks through the limitations of traditional flat displays. Its screen is spherical or approximately spherical, and can achieve full viewing angle of 360°. No matter which angle the audience watches, they can get a clear and blind spot-free visual experience. Compared with traditional LED screens, spherical screens not only have more artistic and futuristic appearance, but also can directly present the dynamic picture of spherical objects (such as the earth, football, etc.) through projection technology, bringing an immersive visual impact.

The spherical LED screen is usually spliced ​​by multiple LED modules. The module size has been carefully designed to ensure the consistent spherical curvature and the screen display is smooth. This kind of screen is widely used in science and technology exhibition halls, commercial advertisements, theme parks, hotel lobbies and other scenarios, becoming an eye-catching "traffic responsibility". Take you a comprehensive understanding of the spherical LED display.

Core parameters of spherical LED display

To understand the performance and applicable scenarios of spherical LED displays, the key is to master the following core parameters:

Diameter dimensions

The diameter of the spherical LED screen can be customized according to customer needs, and the common sizes range from 0.5 meters to 8 meters. For example, SoStron once created a spherical screen with a diameter of 8 meters for Morocco, which is a landmark display. The diameter size directly affects the display area and installation space, and needs to be selected according to the actual scene. What should I consider when customizing LED digital screens?

Pixel spacing (point spacing)

Pixel spacing is a key indicator for measuring the clarity of the display, in millimeters (such as P2 and P3). The smaller the spacing, the more delicate the picture, but the higher the cost. The common spacing of spherical LED screens is P2 to P4, which is suitable for indoor high-definition display; outdoors are mostly P5 or above to suit long-distance viewing. Provide you with a guide to selecting LED display spacing.

Resolution

The resolution of a spherical screen depends on the pixel pitch and the sphere surface area. High-quality spherical screens often require high resolution to ensure clear picture details. For example, the spherical screen of indoor P2.5 can achieve delicate image performance and is suitable for close viewing.

Brightness and contrast

The LED spherical screen uses high-brightness LED light beads, with brightness up to 800-2000 nits (nits), high contrast, and can keep the picture clear even in a strong light environment. The brightness of the indoor screen is slightly lower, while the brightness of the outdoor screen needs to be higher to fight against the sun. Provide you with knowledge about nit brightness.

Refresh rate

The refresh rate determines the smoothness of the picture, which is commonly 1920Hz to 3840Hz. High refresh rate is suitable for dynamic video playback, avoiding flickering, especially when shooting.

Protection level

Outdoor spherical screens must have waterproof and dustproof functions, and the protection level is usually IP65 or above to ensure stable operation in bad weather. Indoor screens have low protection requirements. Take you to learn about LED IP levels in 5 minutes.

Production process

There are various ways to make spherical screens, including fan blade rotary type, triangular splicing type, flexible module splicing, etc. Each process has different effects on installation and display effects. For example, the fan blade rotating type forms a spherical surface through high-speed rotation, which is cheaper but complicated to maintain; the flexible module is more suitable for customization needs.

Factors influencing the price of spherical LED displays

The prices of spherical LED displays vary by parameter, process and customization demand, and the overall price range is wider, ranging from tens of thousands of dollars to hundreds of thousands of dollars. Here are the main factors that affect prices:

Size and resolution

The larger the diameter and the smaller the pixel spacing, the higher the price. For example, the price of a 1-meter-diameter P2.5 indoor spherical screen may be between 100,000 and 100,000 US dollars, while an 8-meter-diameter outdoor P5 spherical screen may be as high as more than one million yuan.

Materials and Process

High-end spherical screens adopt COB packaging technology (such as the Cobra series), which has better display effect but higher cost; traditional SMD packaging is more cost-effective. In addition, the modules and precision splicing processes of CNC machining will also push up prices. We will introduce you to the 6 differences between SMD LED display and COB LED display.

Customized requirements

Spherical screens are mostly customized products, and special shapes (such as open and closed spherical screens) or interactive functions (such as touch, dynamic sensing) will significantly increase the cost.

Installation and maintenance

The installation of spherical screens requires a professional team, involving lifting, bracket design, etc., and the cost accounts for 10%-20% of the total cost. Later maintenance (such as module replacement) also needs to be considered, especially outdoor screens are greatly affected by the environment.

Brand and Service

Well-known brands such as Zhouming Technology and Lianchengfa provide more reliable quality and after-sales service, and the prices are relatively high. Small and medium-sized manufacturers may have lower prices, but they need to pay attention to product quality and after-sales guarantee.

Market price reference

According to market data, the price of small and medium-sized indoor spherical LED screens (diameter 1-2 meters, P2.5-P4) is usually between 50,000 and 200,000 US dollars; the price of large outdoor spherical screens (diameter 3 meters, P5-P10) is mostly above 200,000 US dollars. For specific quotations, please consult a professional manufacturer, such as SoStron, to obtain detailed quotations.

Application scenarios and advantages

The spherical LED display is suitable for a variety of scenarios due to its unique appearance and functions:

Commercial display: The spherical screens in shopping malls and hotel lobbies can play advertisements or brand videos to attract customers.

Cultural exhibitions: Museums and science and technology museums often use spherical screens to simulate the earth, planet, etc. to enhance the interactive experience.

Event stage: Use spherical screens to create shocking visual effects in concerts, weddings and other occasions.

Its main advantages include: 360° no blind angle display, high brightness and high contrast, visual impact brought by personalized design, and flexible installation methods (such as lifting and flooring).

Summarize

With its unique design and high-definition display, the spherical LED display is changing the definition of traditional visual experience. Although prices vary by size, resolution and process, the visual shock and brand value it brings are irreplaceable. If you are looking for a display device that will enhance the impact of your project, consider a spherical LED screen. Contact a professional manufacturer and customize your exclusive visual feast!
