Color cathode ray tube having an internal voltage-dividing resistor |
摘要 |
A color cathode ray tube has an electron gun in its neck portion. Its focus electrodes and anode are fixed by two insulating support rods. A voltage-dividing resistor is disposed in the vicinity of one of the insulating support rods for producing an intermediate voltage applied to a first one of the focus electrodes adjacent to the anode by dividing an anode voltage. The voltage-dividing resistor includes an insulating film, a resistance pattern, an insulating substrate, and a second film containing an oxide of transition metal, in the order named from the insulating film toward the inner wall of the neck portion. A metal conductor surrounding the voltage-dividing resistor and the one of the insulating support rods is fixed to a second one of the focus electrodes which is disposed upstream of the first one of the focus electrodes in a path of the electron beams.
