A color cathode-ray tube (CRT) having an evacuated envelope with an electron gun therein for generating at least one electron beam is disclosed. The envelope further includes a faceplate panel having a luminescent screen with phosphor lines on an interior surface thereof. A tension focus mask, having a plurality of spaced-apart first electrodes, is located adjacent to an effective picture area of the screen. The plurality of spaced-apart first electrodes has a screen-facing side having a predetermined width and a relatively wider electron-gun-facing side. Each side forming sharp corner edges extending along the length of each first electrodes. A substantially continuous insulating material is deposited on the screen-facing side and on the corners of the first electrodes to shield the sharp corner edges of the first electrodes. A plurality of second electrodes are oriented substantially perpendicular to the plurality of first electrodes and are bonded thereto by the insulating material layer.
A cathode-ray tube comprising an evacuated envelope having therein an electron gun for generating at least one electron beam, a faceplate panel having a luminescent screen with phosphor lines on an interior surface thereof, and a tension focus mask, wherein the tension focus mask includes a plurality of elongated spaced-apart first electrodes which are substantially parallel to each other, and a plurality of spaced-apart second electrodes oriented substantially perpendicular to the plurality of spaced-apart first electrodes, said plurality of spaced-apart first electrodes comprising:
A cathode-ray tube comprising an evacuated envelope having therein an electron gun for generating at least one electron beam, a faceplate panel having a luminescent screen with phosphor lines on an interior surface thereof, and a tension mask oriented between the electron gun and the screen, said tension mask comprising:
