Method of forming fluorescent screen of cathode ray tube |
摘要 |
A method of forming a phosphor layer of a fluorescent screen of a CRT, having a good screen quality by properly managing the dissolution of a water glass and barium acetate occurring in a covering water step and improve the uniformity. A phosphor layer is formed on an inner surface of a panel portion of a glass bulb by a precipitation process and a lacquer intermediate film is formed on the phosphor layer in a state where the phosphor layer is moistened by covering water. An electrolyte remaining in the phosphor layer after the phosphor layer is moistened by the covering water has a conductivity of 6.0+/-4.0 mu s/cm in 200 ml of pure water of 20 DEG C.+/-1 DEG C.
