How is the LED spherical screen made?

As an innovative display medium, LED spherical screen breaks through the limitations of traditional flat display with its unique three-dimensional structure and vivid image display. Its production process covers many aspects of professional technology from design conception, precision component processing to complex space splicing and hardware and software integration, and the precise calculation and layout design of the pixel on the surface of the sphere is to highlight the charm of the combination of technology and art.

The production process of LED spherical screen involves the combination of precision technology and art, ‌ including design, ‌ production, ‌ debugging and other stages. ‌

Firstly, ‌ the designer makes a detailed plan according to the project requirements and specifications, ‌ determines the sphere diameter, ‌ resolution and pixel spacing. ‌ uses flexible and flexible LED display modules as the basic building block ‌ these modules consist of densely arranged red, green and blue LED beads ‌ capable of presenting rich colors and delicate images. ‌ In the production link, ‌LED module is assembled one by one according to the shape of spherical surface after special cutting, ‌ folding and splicing technology. ‌ In order to ensure the smooth and flawless surface of the sphere, ‌ technicians use customized connecting parts and curved brackets, ‌ to ensure seamless docking between modules, ‌ to form a continuous and uniform display interface. ‌ At the same time, the ‌ built-in driving circuit, ‌ control board and power supply system also need to be designed and arranged specifically, ‌ in order to achieve stable signal transmission and power supply. ‌

In addition, the manufacturing of ‌LED spherical screen also includes the later hardware and software debugging stage. ‌ Through professional calibration software, ‌ for each LED pixel color, ‌ brightness consistency correction, ‌ to ensure the whole ball image quality balance. ‌ At the same time, ‌ develops or adopts an image processing algorithm suitable for spherical projection, ‌ makes two-dimensional video content can accurately fit and transform on the spherical surface, ‌ presents distortion-free immersive visual effect. ‌

For the pixel calculation of LED spherical display, ‌ because the surface of the sphere is not flat, ‌ its pixel distribution is not as simple as the traditional rectangular display can be used to describe the resolution. ‌ Calculating the number of pixels for a spherical screen is based on the surface area of the sphere and the selected pixel spacing. ‌ firstly, the total area of the sphere is estimated by using the formula of surface area of the sphere. ‌ then, according to the pixel spacing and radius of the sphere, ‌ simulates the pixel grid distribution on the sphere. ‌ considering that the pixel density of ‌ will vary with the latitude. ‌ This means that different regions of the sphere are analyzed in detail during the calculation process, ‌ counting the number of pixels each can hold. ‌ The final total number of pixels, ‌ refers to the total number of all independently controllable LED luminous points that ‌ can effectively cover the entire surface of the sphere and achieve the ideal display effect without causing obvious distortion. ‌

Spherical screens play an important role in the field of art and design. ‌ artists and designers can use spherical screen to create unique art works and design works, ‌ to provide more creative space and visual presentation, ‌ to make artistic works more three-dimensional sense and imagination.
