摘要： In a cathode ray display tube having a glass faceplate (14) carrying a screen (16) thereon including a screen electrode (18) and an electron multiplier (44) disposed adjacent the screen for current-multiplying an electron beam directed onto the screen, a low profile termination arrangement for establishing electrical connection with the screen electrode and a multiplier electrode comprises respective, spaced, thick film conductive tracks (46 and 45) on the inner surface of the faceplate and bordering the screen connected at lead-in portions thereof with conductor means (57), e.g. conductive epoxy, in apertures (56) extending through the faceplate via metal sealing discs 55. A spacing frame 48 bearing against track 45 supports the multiplier away from the screen and contacts its output electrode (50) to provide connection with track (45). The screen electrode (18) overlies the track (46) around the screen.

摘要： In a flat cathode ray display tube having an electron gun (30) adjacent a rear wall (15) of the tube's envelope which produces an electron beam travelling across the rear wall before being turned in the opposite direction and then deflected onto a screen carried by faceplate (14) opposite the rear wall, getter means (60) is situated in one or more recesses (57), each defined at least in part by an elongate rib (55) formed in the rear wall, e.g. by pressing, with the recess wall shielding the getter means directly from the gun to prevent contamination. The rib serves also to strengthen the rear wall. A line scanning deflector (34) is similarly shielded.
