KR980005237A - Film for manufacturing deflection member of cathode ray tube and deflection member laminated and molded - Google Patents

Abstract

The present invention provides a cathode ray tube capable of producing a deflection member by laminating a plurality of flattened films without forming or damaging films or wires, and without forming defects such as wrinkles, and molding the films in a predetermined shape at the deflection portions thereof. Provided are a film for producing a deflection member, and a deflection member obtained by laminating and molding the deflection member. The film is characterized in that a thermosetting resin layer is formed on at least one of the base layer, the insulating adhesive, and the upper protective layer constituting the film. In addition, when the reinforcing member is disposed above and below the laminated film, the thermosetting resin layer may be formed therebetween, and the thermosetting resin layer is formed by applying a thermosetting resin solution or laminating a thermosetting resin sheet. Accordingly, by molding each film or the reinforcing member in a predetermined shape, it is possible to stably solidify it into a predetermined shape, and furthermore, the deformation due to the temperature rise does not occur even during operation of the cathode ray tube. There is an effect such that the deflection magnetic field pattern becomes constant without change over time.
