Abstract: A CRT display including a display panel having a substantially flat outside surface, and an inside surface with a substantially fixed curvature includes a film coating with a non-uniform transmissivity. The film coating's transmissivity is varied, as a function of position, to compensate for variations in transmissivity exhibited by the display panel, thus resulting in substantially uniform image brightness across the surface of the CRT.
