Abstract:
A colour display tube comprising a display window with corner areas, a colour selection electrode having corner sections with supporting elements, each of which includes a free end portion, and suspension means, each comprising a generally flat resilient element and a generally flat portion that flushly mates to the resilient element and that includes an apertured part having an entrance opening, wherein the colour selection electrode is suspended from said free end portions, each of which is engaged with an associated apertured part by three contact points which are located on surfaces of engagement, and such that each free end portion has a centre which substantially coincides with a plane through an associated resilient element, wherein at least one of the contact points of each apertured part is situated outside the plane of the associated resilient element and on a surface of engagement, wherein at least one of the other two contact points of each apertured part substantially coincides with the plane of the associated resilient element, wherein at least one of the other two contact points is located on a surface of engagement that is substantially perpendicular to that plane, and wherein the surface of engagement of said contact point that is situated outside that plane is substantially perpendicular to a line between the contact point that is situated outside of that plane and the centre of the associated free end portion, which free end portion passes through the associated entrance opening.
