Problems solved by technology

These solutions are also immobile and have the additional problem of acoustic reflections that degrade the user experience
Finally, modular spherical screen assemblies exist, but require color-matched filler between the gaps of each rigid module, which is time consuming and not portable

Embodiment Construction

[0010] In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration specific embodiments which may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and structural, logical, and electrical changes may be made without departing from the scope of the invention. Accordingly, the following description of example embodiments should not be read in a limiting sense, and the scope of the invention is defined by the appended claims.

[0011] The modular curved projection screen consists of an outer structural assembly supporting multiple inner compound curved screen assemblies. A plurality of compound curved screen assemblies creates a concave viewing area for projecting images onto the compound curved screen assemblies. The curved screen assembly...

Abstract

A modular curved projection screen includes an outer structural component formed of multiple compound curved interlocking sections. Multiple inner compound curved screen components are each supportedby a corresponding compound curved interlocking section and extend beyond edges of the interlocking sections. Responsive to interlocking the multiple compound curved interlocking sections, edges of adjacent screen components are compressed against each other to form a smooth concave projection viewing area supported by the outer structural component.

Description

Background technique [0001] Massively recessed, compound curved projection screens are most commonly constructed of formed and painted perforated aluminum panels attached to a steel exterior frame. This technology is not portable, and it is expensive and fragile. Such screens are not easily scaled down to systems smaller than 25 feet in diameter. Large-scale mobile screen surfaces can be created by fabric wrapping that covers the frame structure, followed by the use of a vacuum between the surfaces to form the desired shape. The fabric screen surface shows gaps between adjacent panels and exhibits cushioning caused by differential stretching of the fabric panels. Smaller screen surfaces are typically made using formed FRG (Fiberglass Reinforced Gypsum) board (drywall) and caulk compound or molded fiberglass. These solutions are also immobile and have the additional problem of acoustic reflections degrading the user experience. Finally, modular spherical screen assemblies e...
