Termination arrangement for a cathode ray display tube
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.
