Analyze the difference between spherical screen and special-shaped screen in detail

 

 

 

 

Spherical screen and special-shaped screen are new technologies in the LED display industry, which have brought a more dazzling effect to the display industry.

 

 

1. Definitions and characteristics
Spherical screen
Definition: Spherical screen is a kind of LED display with a spherical appearance, which is usually spliced by multiple spherical units to form a complete spherical structure.
Features: 360-degree viewing angle, the audience can view the screen from any angle to get a clear and realistic image. In addition, the spherical screen is highly flexible and designable, and can be customized according to needs.
Special-shaped screen
Definition: Special-shaped screen refers to non-traditional rectangular or flat shape LED displays, including round, triangular, arc, wavy and other shapes.
Features: Break the limitation of the regular shape of the traditional LED display and have a stronger visual shock effect. The special-shaped screen can better adapt to the overall structure and environment of the building, and the size and size of the screen can be customized according to the requirements.

 

 

2.The structure of the composition
Spherical screen
It is mainly composed of spherical unit, display board bracket, LED light board, power supply, unit control board and other components. The spherical units are connected to each other to form a spherical display, and the warp and weft spokes in the display board assembly are snapped together through the tenon to support and fix.
Special-shaped screen
The structure of the special-shaped screen is relatively complex, because of the variety of shapes, so the structure of each special-shaped screen may be different. It is usually made up of multiple irregularly shaped LED modules that need to be customized to a specific shape and size.

 

3. Display principle
Spherical screen
The LED lights on the LED light board are controlled through the control board, so that the LED lights emit light according to specific image and video signals, so as to present various contents on the spherical screen. The pixels of the spherical screen are distributed on the spherical surface, which requires special technology and algorithms to achieve the correct display of the image.
Special-shaped screen
The display principle of the special-shaped screen is similar to that of the spherical screen, and it is also composed of an image by controlling the on-off and color changes of the LED lights. However, due to the variety of shapes of special-shaped screens, more complex algorithms and control systems may be required to ensure the accurate display of images.

 

 

4.The field of application
Spherical screen
Spherical screens are widely used in museums, science and technology museums, exhibition halls and other places to display various contents. In addition, spherical screens can also be used in commercials, stage backgrounds, and other fields to provide unique visual effects.
Special-shaped screen
The application field of special-shaped screen is more extensive, including commercial plazas, exhibition halls, parks, stadiums, large-scale performances, etc. The special-shaped screen can be customized according to different places and needs, bringing more colorful visual effects to the audience.

 

5. Technical advantages and challenges
Spherical screen
Technical advantages: The spherical screen has a high degree of flexibility and designability, and can be customized according to needs. At the same time, the 360-degree all-round viewing angle of the spherical screen provides a unique visual experience.
Technical challenges: The fabrication and installation of spherical screens is relatively complex, requiring precise calculation and installation techniques. In addition, the pixels of the spherical screen are distributed on the spherical surface, which requires special technology and algorithms to achieve the correct display of the image.
Special-shaped screen
Technical advantages: The special-shaped screen can break the limitation of the regular shape of the traditional LED display and has a stronger visual shock effect. The special-shaped screen can be customized according to different places and needs to meet the individual needs of customers.
Technical challenges: The production and installation of special-shaped screens are relatively complex, because of the variety of shapes, so the production of each special-shaped screen requires accurate calculation and design. In addition, the splicing and debugging of special-shaped screens also require a high technical level.
