A LED Sphere display, also known as an LED ball screen or LED video ball, is a creatively designed type of LED screen product. With its spherical shape, it can provide a 360-degree viewing angle effect.
This display is different from traditional LED screens because of its unique 360-degree spherical appearance.Due to its distinctive design and visibility from any angle, it stands out among various LED displays.
The images and videos displayed by the LED spherical display have no image distortion and can immediately attract public attention.
These displays are typically hung indoors in shopping malls. Moreover, they are an excellent choice for large public places, such as museum halls, casinos, game halls, and airports, where fascinating images or videos need to be displayed and interact with audiences.
Full-color LED spherical screens are mainly used in museums, hotel lobbies, offices, art museums, science and technology centers, corporate exhibition halls, and other indoor and outdoor exhibition spaces, as well as for outdoor spherical video advertisements and unique spherical lighting projects. The following are some application scenarios for spherical LED displays.

The LED sphere display is made up of several components, including a core control module, a rotating display module, a wireless module, a font module, a motor drive module, and a power supply. The fan blade is designed in a circular shape, with a circle of LED lamp beads on it. The LEDs can emit monochromatic or multicolor light.
When the fan blade rotates around the central axis, it creates a spherical surface. The entire surface consists of LEDs, which can be controlled using the font software. By lighting up the corresponding points on the spherical surface, the display content can be controlled and displayed accurately.
The emergence of LED electronic displays not only brings great convenience to our lives but also adds beauty to our cities. With continuous improvements in LED display technology, designs have become increasingly artistic and aesthetically pleasing. LED displays of various shapes, such as “wave-shaped” and “spherical,” have appeared. The spherical LED display, a fashionable, beautiful, and flexible LED display product newly developed in recent years, stands out from ordinary LED displays due to its unique process and craftsmanship.
There are two types of spherical LED display screens in terms of production: the first type is a full spherical LED display screen. This type is relatively small, about 2 meters in diameter, and can be viewed as a whole from close-up. The second type is a hemispherical LED display, which is typically larger and needs to be viewed from a distance.
Composed of watermelon skin-like PCBs, the advantage is that the structure is intuitive and there are fewer types of PCBs. The disadvantage is that the north and south poles (that is, north of 45° north latitude and south of 45° south latitude) cannot play images normally, so the picture utilization is too low or the image is severely deformed. The reason is that the pixel points of all current image sources are arranged in rows and columns, and the pixel points of the north and south poles of the watermelon rind LED spherical screen are not arranged in rows and columns, but arranged in a circle, so It is difficult to display.
The spherical screen composed of a flat triangular PCB overcomes the shortcoming that the north and south poles of the watermelon rind spherical screen cannot play images, so the picture utilization rate is greatly improved. The disadvantage is that there are many types of PCBs, limited by the honeycomb arrangement of pixels, the dot pitch cannot be too small, and software writing is also more troublesome.
The spherical LED display composed of a quadrilateral PCB has the advantage of being closer to a flat LED display. The minimum dot pitch is similar to that of a flat LED display. There is little or no restriction, so the effect is much better than that of a triangular PCB.
The resolution design of a spherical LED display is the same as that of conventional LED displays, and it depends on the viewing distance. For example, if the display is viewed from 2.5 meters away, it is recommended to choose the P2.5 or P2 model. For viewing at 6 meters, it is recommended to choose P6 or P5. If budget allows, a higher definition model such as P4 or P3 can be selected.
For outdoor viewing at a distance of 10 meters, the P10 model is generally the best option, but this choice is more qualitative than quantitative. The specific installation environment, audience, and budget should be taken into account when making a decision.
LED video sphere, also called LED video ball, refers to the ability to play videos and graphics after splicing LED modules into the shape of a ball.
Because the visual feel is hugely different from the square LED displays we usually see, the spherical LED display is more eye-catching.
