Abstract:
A large-area electroluminescent (EL) faceplate for storage CRT is described. The EL faceplate has a non-planar mesh structure which includes individual current limiting resistance between a power source and an array of small-area active regions for improving the faceplate breakdown characteristics. The mesh, which comprises high conductivity strips and delivers power to the active regions, is substantially reduced in area relative to a simple conventional device, and is disposed on thick dielectric nonactive regions to further reduce the possibility of catastrophic breakdown.
Abstract:
The dielectric, which is provided on either side of the active phosphor in an AC-driven electroluminescent display, is formed of a composite material which has both high dielectric constant and high resistivity. Preferably, a composite of titanum dioxide and alumina is used.
Abstract:
A light filtering system for improving the spectral output from fluorescent lamps. A filter placed within the lamp envelope between the phosphor coating and the arc discharge path between the lamp electrodes, absorbs mercury arc radiation in the visible range while passing arc radiation in the ultraviolet range to excite the phoshor coating and produce visible light emitted through the outer envelope.
