This paper shows that phosphor screens for cathode ray tubes (CRTs) prepared by electrophoresis can demonstrate brightness equal to the standard settling coating process and are capable of very high resolution. Typical screens investigated were sulfides, oxysulfides, silicates, oxides, and others. The process used is based on McGee et al. (7) with modifications. Descriptions are given of the various process parameters. In particular it is shown both by resolution and optical measurements that the electrophoretic process produces screens with markedly different optical characteristics compared to settling. The screen performance is described for sealed off and demountable CRTs.
