TWO-SIDED FILM FOR A FILM-TYPE DEFLECTION MEMBER USED IN A CATHODE RAY TUBE

摘要

Disclosed is a two-sided film (F1 to F4) for a film-type deflection member of a cathode ray tube, which can obtain an ampere turn for a predetermined magnetic-field pattern while reducing the number of films, connection terminals, wires, and slant portions in the wire. The two-sided film has a deflection section (TF) formed at upper and lower surfaces of a base thereof with plural pairs of wires arranged in a predetermined pattern, and a pair of connection sections (CF, CF') for electrically connecting the plural pairs of wires to an external power source. The deflection section (TF) produces a predetermined magnetic field pattern as a current is applied to the wires. Each of connection sections (CF, CF') is formed at both sides of the deflection section (TF) and extends by a predetermined length therefrom. The wires are branched into two strands at the deflection section (TF), and each pair of wires is connected to each other in a parallel pattern at the deflection section.
