Abstract

1536776 Cathode-ray display tubes ENGLISH ELECTRIC VALVE CO Ltd 20 April 1977 [10 July 1976] 28793/76 Heading HID Exposed to a flood gun in a CRT, with conical electrode coating 15 and field grid electrode 16 at 0-15V above cathode, insulated preferably row and column mesh electrode sets (Fig. 2, not shown) 7 and 8 are separately addressed to block electrons when non-positive and to pass, when a few volts positive, electrons to the flucrescent screen 3 at high + voltage, allowing intersecting areas to be illuminated in succession, so building up symbols. The mesh pitch of the electrode set 7 nearer the gun may preferably be coarser than that of the set 8.
