Abstract

A cathode ray tube has a thin flexible circuit (48) comprising one or more films of polyimide with a plurality of conductive tracks deposited directly thereon for establishing electrical connection between a multi-pin lead through (45) passing through the wall of the tube's envelope (31) and terminals of electrically operable components within the envelope, e.g. electron gun (35) and beam-deflection electrodes (36,39 and 40). A number of track-carrying films may be stacked together to form a laminate structure. Such a flexible circuit avoids outgassing problems and, being thin and flexible, occupies minimal space and is easily routed around internal components to ease assembly.
