Patent number: 5656885Abstract: 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.Type: GrantFiled: January 29, 1993Date of Patent: August 12, 1997Assignee: Sony CorporationInventors: Yoji Kohno, Ichiro Utsumi

Patent number: 5418075Abstract: On a long base film (7) made of polyethylene terephthalate, there are formed a stripping layer (8), an aluminum layer (9), a phosphor layer (10) and a bonding layer (11) to construct a thermal transfer foil (P). A phosphor screen is formed on a glass panel by using the thermal transfer foil (P). In the process for forming a phosphor layer of a cathode ray tube, the number of manufacturing processes can be reduced so that a manufacturing cost of the phosphor screen can be reduced. Also, there can be obtained a stable phosphor screen having a constant film thickness.Type: GrantFiled: February 18, 1993Date of Patent: May 23, 1995Assignee: Sony CorporationInventor: Ichiro Utsumi
