Principle of Spherical LED Display

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.

Analysis of the manufacturing method of spherical LED display

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.

There are roughly the following methods for making spherical LED display screens:

1. For outdoor spherical LED displays with larger diameters, single-pixel tubes can be used. Cut the ball according to the latitude, and place a row of LED pixel tubes at each latitude.
2. For indoor spherical LED displays with smaller diameters, you can use surface mount three-in-one LED lights, use flexible PCB boards to make point-by-point controllable light strips, and then the light strips, like the first form, surround the sphere according to the latitude.
3. For indoor screens, special LED unit boards can also be designed according to the dot pitch. The special-shaped unit board can be designed as a triangle for splicing, or it can be designed as a hexagon for splicing (just like a football, it is composed of multiple hexagons). The indoor LED spherical screen models are: P4, P5, P6, and P10 And many other models are available.

Advantages of spherical LED display:

• Seamless splicing: adopting trapezoidal circuit design, can realize seamless splicing;
• Uniform tapping: Supports uniform tapping technology, and the display screen is not distorted;
• Flexible control: Synchronous and asynchronous compatible, supporting both offline and online modes;
• Good heat dissipation: use aluminum structural heat dissipation solutions;
• Convenient installation: As a complete system, it supports floor installation, hoisting, embedded installation, etc.;
• Convenient maintenance: support pre-maintenance and post-maintenance;

 Features Introduction:

1. The spherical full-color LED display can be used outdoors and indoors. It is translucent, has a large display pixel pitch, and has a certain decorative effect. It is used in large screen display occasions. It is a common conventional display and lighting. An LED display application product between;
2. After special treatment, the display unit can be assembled into an inner arc display surface, outer arc display surface, inner circle display surface, S display surface, spherical shape, and other special-shaped screens, which are not available for ordinary conventional displays. Achieved display effect;
3. To ensure sufficient brightness of the pixels in the outdoor reality project, the front of the pixel is potted with silica gel for waterproofing. The color of the silica gel can be matched with the color card according to the project requirements so that it can be perfectly coordinated with the color of the exterior wall of the building;
4. The pixel outlet is a silicone wire with excellent high and low temperatures, with professional waterproof connectors, and a professionally designed and carefully built fully sealed waterproof structure. The protection level reaches IP67. It can adapt to various indoor and outdoor temperature and humidity environments, and the working environment range can reach -20 And +80 degrees Celsius, can work in rain;
5. The spherical LED display adopts a bar-shaped display unit, which has a strong visual impact and high safety factor;
6. The viewing angle of the spherical LED display is 360 degrees, the video is played in all directions, and there is no viewing angle problem of the flat LED display;
7. Multiple pixels in series or parallel can realize full-color display and can play video. The LED ball can be synchronized or asynchronously controlled to display full-color video.
8. The spherical LED display is equipped with a professional audio and video processing system, supports a variety of external signal access, and can realize live broadcasts.
9. The diameter of the LED ball display can be designed and produced according to customer requirements. The spherical surface is completely completed by CNC. The precise module size ensures the uniformity of the overall curvature of the LED ball display.
10. The spherical LED display does not need to be installed, it can be used when the goods arrive, no installation is required!
11. The spherical LED display has the advantages of being lightweight, having good wind resistance, convenient installation, good heat dissipation performance, convenient front, and rear maintenance, good waterproof performance, good seismic performance, low cost of auxiliary installation frame, no fan and quietness;
12. It can be the same as the rental LED display. It has an all-aluminum structure design, lightweight and strong structure. The installation method of the LED ball can be designed as a mobile, hoisted, and seated according to customer requirements;
13. According to customer requirements and site environment, tailor the most suitable spherical LED display solution;

Spherical LED display type

1. Watermelon rind

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.

2. Triangular

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.

3. Six-sided

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.

How to choose a spherical display?

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.
