Title: Improvements in or relating to cathode ray tube display systems
Inventor: PLAISTOWE DONALD LEOPOLD
IPC: H01J31/64
Filed: 1958-03-20
Abstract: 826,334. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Oct. 7, 1958 [March 20, 1958], No. 9015/58. Class 39(1). [Also in Group XL(c)] A cathode-ray display tube, for use in a space scanning radar system, comprises three electron guns 9, 11, 23, two positioned to bombard one side of a target structure and the third positioned to bombard the other. The target structure includes a fluorescent screen 5 with exposed fluorescent surfaces on both sides thereof, both being visible from the side facing gun 23, and a storage grid 6 on the side of the screen facing guns 9 and 11. The ray from gun 11 is modulated by video signals and scanned over the target structure in a predetermined pattern whereby grid 6 is stored with charges representative of the signals. A persistent fluorescent display corresponding to the sorted charge pattern is produced by causing gun 9 to flood the target structure substantially uniformly with electrons. Independent means are provided for deflecting the ray from gun 23, which may be modulated in accordance with further signals, over the target structure. As shown, the ray from gun 11 is modulated by signals obtained from a radar receiver 13. The ray from gun 23 may be used to mark any desired spot on the screen by connecting an adjustable marker voltage source 27 to the deflection coils 24, or alternatively the ray may be modulated in accordance with video signals representative of a desired picture e.g. a map 31, and scanned over the screen in a television raster to obtain a non-persistent display. The composite picture produced on the screen 5 may be viewed through window 8 or reflected by mirror 34 to a television camera 35. The fluorescent screen 5 may comprise a fine aluminium mesh, the holes of which are filled with a suitable phosphor, having a light transparent aluminium layer facing the storage grid 6, which may be a fine aluminium mesh thinly coated with insulating material, e.g. it may be oxidised on the side facing secondary-electron collector grid 7. Alternatively the screen 5 may comprise a light transparent metal film with closely spaced lines of fluorescent material on both sides, the lines of fluorescent material on one side being opposite the spaces between the lines on the other. In this case the material used on the two sides may be chosen to fluoresce in different colours so that the presistent part of the composite picture is produced in one colour and the non-persistent part in another.
