The disclosed technical solution relates to the development of surfaces that are display screens on which an image or a video sequence are presented on a curved surface, in particular, on a surface resembling a spherical one. The foundation of the claimed invention lies in the objective of creating a spherical modular video screen, which is formed by a limited number of types of unique elements, where the number of types of unique elements is clearly defined, and the size of the spherical modular video screen can be altered by adding or removing said elements. This provides a design of a device for displaying a visual sequence that allows for adjustment of the spherical modular video screen's radius according to a predetermined step. The technical result attained by implementing the spherical modular video screen is the reduction in the number of unique element types constituting the spherical modular video screen. The specified novel attribute is achieved through the implementation of an innovative construction principle.
