Abstract
A cathode ray tube (1) having an improved deflection unit (11) is described. The deflection unit (11) comprises line and/or frame coils that comprise a composition of wires having a conductive coating and wires having a non-conductive coating. Such deflection units have a good anti-ringing performance, while the good adhesion characteristics of non-conducting coated wires are maintained.
Claims5
A cathode ray tube (1) comprising an electron gun (6) for generating at least one electron beam (7), and a deflection unit (11) for deflecting the at least one electron beam (7) across a display screen (10), the deflection unit (11) comprising a line deflection coil system (12) and a frame deflection coil system (13), the line deflection coil system (12) and/or the frame deflection coil system (13) having coils which are at least partly provided with a conductive layer, characterized in that the coils comprise a composition of first electrically conductive wires having an electrically non-conductive layer surrounding the first electrically conductive wires and second electrically conductive wires having an electrically conductive layer surrounding the second electrically conductive wires.
A deflection coil system (12,13) having coils, which are at least partly provided with a conductive layer, wherein the coils comprise a composition of first electrically conductive wires having an electrically non-conductive layer surrounding the first electrically conductive wires and second electrically conductive wires having an electrically conductive layer surrounding the second electrically conductive wires.
