ABSTRACT
Powdered phosphors are used as the screen that arranges phosphor particles (
ϕ
=
µ
m on average) with thicknesses of approximately 4 mg cm
on the faceplates of display devices. Phosphor screens in cathode ray tubes (CRTs) have many screening problems related to the phosphor powders. Here we delve into the screening problems of phosphor powders on the faceplates of color CRTs. The results are applicable to phosphor screens of photoluminescent (PL) devices.
