Flat CRT having a carbon layer on an inner surface of a back panel |
摘要 |
The present invention is directed to a transmission type flat cathode ray tube in which a flat glass tube envelope (15) is formed of a triple structure having a screen panel (11), a back panel (12) and a funnel portion (14) having a neck portion (13). A carbon film (24) to which an anode voltage is applied is formed on the inner surface of the back panel 12 in an opposing relation to a phosphor screen (19) of the screen panel (11). Thus, the occurrence of a pseudo signal in the transmission type flat cathode ray tube can be avoided.
