<p>A display arrangement comprises a cathode ray tube, inside which tube a mask with at least one curved outer edge is located. The mask is at least partly attached by at least part of the curved edge to the tube by means of at least a diaphragm arrangement. The diaphragm arrangement comprises at least one diaphragm part (300) in the form of an elongated folded sheet comprising a straight fold (302), said sheet extending from the straight fold to a curved fold (304) and from the curved fold to a curved part (305) of the sheet for attaching to the curved mask edge. Preferably, the straight fold has a varying folding angle and the curved fold follows a curve which enables the transition from the straight fold to the curved fold to provide a folded sheet which is free from inherent mechanical stress.</p> |
