ABSTRACT:
An electron gun assembly for a cathode ray tube includes a cathode for emitting an electron beam, and a plurality of electrodes mounted in a row with predetermined gaps therebetween. The electrodes include a focus electrode for receiving a focus voltage, and an anode electrode surrounding part of the focus electrode for receiving an anode voltage. A support is used to fix the electrodes in an aligned configuration, and a first auxiliary support secures the focus electrode to the support. The focus electrode includes an intermediate aperture section, a small aperture section, and a large aperture section, while the anode electrode includes a large aperture section and a small aperture section. Two second auxiliary supports secure the anode electrode to the support.
