Abstract

The invention relates to a folding holographic projection screen/diffuser of the type which, when assembled, forms a square-based pyramidal frustum (1) with four side faces (2), made from an essentially transparent material, but without top and bottom faces (3), characterised in that respective connecting members (4) are provided on the sides (20) of the side faces (2) and are designed to pivotably connect contiguous side faces (2-2) so as to form the aforementioned square-based pyramidal frustum (1), with at least one of said connecting elements (4) being intended to be detached/detached from the corresponding associated side face (20) such that the side faces (2) can be stacked on top of one another in a folded configuration, or assembled to form the pyramidal frustum.
