摘要:
An admixture of Yttrium oxide, or yttrium oxysulfide, or yttrium oxide or yttrium oxysulfide activated by a rare earth element and P1 phosphor, manganese-activated zinc orthosilicate provides a viewable bistable storage target for cathode ray tubes having increased operating life.
摘要:
A color difference between stored and write-through (unstored) information displayed by a direct viewing bistable storage CRT is achieved by admixing the storage phosphor with a second phosphor that emits light of a distinctly different color. The second phosphor is chosen to have a lower relative light output efficiency than the storage phosphor under low voltage, flood gun illumination conditions.
