SAMPLE PREPARING METHOD FOR PHOSPHOR LAYER OF CATHODE RAY TUBE

摘要

The phosphor layer adhered to a panel is chemically treated to cause its removal and optionally then cleaned with pure water and heat-treated to obtain a sample of phosphor layer in thin film form. Layer inspections for determining the shape of the phosphor particles, their bonding state, the thickness of the phosphor layer and the film layer and the formation state of the black matrix can be carried out on the prepared sample.
