Title:
DEFLECTION UNIT FOR A CATHODE RAY TUBE
Document Type and Number:
WIPO Patent Application WO2000044028
Kind Code:
A3
Abstract:
The invention relates to a deflection unit (10) for cathode ray tubes in which the external magnetic stray fields are further reduced and the sensitivity of the line deflection coils (17) is increased. This is done by applying a (preferably plastic deformable) magnetic material (56) in the first void spaces (52) between the wire strands (50) of the field deflection coils (18) and/or the second void spaces (54) between the field deflection coils (18) and the yoke ring (22). The plastic deformable magnetic material (56) can be additionally used for adhering the yoke ring (22) to the field deflection coils (18).
