How is the LED spherical display made?

LED spherical display is a new type of spherical display, which can watch the content of the screen in a 360-degree all-round way, bringing a new visual experience, and its picture quality is exquisite and the picture is three-dimensional.

It is mainly composed of five parts: spherical bracket, LED module, LED module, controller and power supply. The spherical bracket plays a supporting role, and the LED module is installed and covered on its surface to form a spherical display screen, which is the core display part, composed of a large number of LED lamp beads, which can be combined into different pictures according to different display requirements; LED module is a complete LED light component, including module, universal photoelectric converter, controller and power supply, can realize a variety of image display; The controller is used to control the brightness and color change of LED lamp beads; The power supply consists of a power cord and a power module that powers the LED module to achieve the display. In addition, it may also include some accessories, such as mounting brackets, supports, distribution boxes, video players, etc., to ensure the normal use of the spherical screen.

The production of LED spherical display mainly has the following ways:

For outdoor spherical LED display with large diameter:

it can be done in the way of a single pixel cylinder. The ball is cut according to latitude, and a row of LED pixel tubes is placed at each latitude.

For indoor spherical LED displays with smaller diameters:

Use a table paste 3-in-1 LED light, use a flexible PCB board to make a point-by-point controllable light belt, and then the light belt is spherical according to the latitude.

According to the point spacing, design a special LED unit board. The special-shaped unit board can be designed as a triangle for splicing, or it can be designed as a 6-sided splicing, just like making a football, which is composed of multiple 6-sided shapes. Indoor LED spherical screen models are P2, P4, P5, P6, P10 and other models to choose from.

LED spherical screen has a wide range of application scenarios, common in the following areas:

1. Museum: The LED spherical screen is installed in a prominent position in the hall of the museum, which can play the video of the development history of the museum and display cultural relics. Its unique appearance can attract the audience’s attention, and the 360-degree viewing Angle can bring visual shock impact;
2. Science and Technology Museum: The spherical screen at the entrance of the Science and Technology Museum can be used to play various celestial and physical phenomena and other content, so that the audience seems to travel in the mysterious vast space, enhancing the viewing experience and science fiction sense of tourists;
3. Exhibition hall: Combined with sound, shadow, light, electricity and other technologies, the dynamic space of the exhibition hall can be displayed in multiple and three-dimensional through the spherical screen, which can bring the audience an immersive 360-degree full perspective audio-visual experience;
4. Outdoor advertising: in star hotels, large open-air places, railway stations, ports, shopping malls and other places, LED spherical screens can be used to play discount advertising and brand image of businesses, attracting the attention of people from all directions, and bringing more potential customers to businesses;
5. Stage performance: It can be used as the background decoration of stage performance to enhance the visual effect of the performance and enhance the viewing experience of the audience by projecting high-definition videos and images;
6. Sports events: Used in sports venues to provide real-time scores, advertising playback, highlights and other content;
7. Public places: such as railway stations, airports, subway stations, etc., play important information, announcements, navigation and other content to provide convenience and information services for people.

The viewing distance of the LED spherical screen at different points is different, and in the case of limited indoor space, a smaller point spacing is usually selected to obtain better visual effects; In the outdoors, in order to balance cost and cost performance, a larger point spacing may be selected. In addition, the outdoor spherical screen also needs to have waterproof, dustproof, anti-ultraviolet, anti-lightning and other properties to adapt to various environmental and climatic conditions. At the same time, it can also be customized according to customer needs of different diameters, shapes, colors and display content, with high flexibility and innovation.
