Abstract
PURPOSE: To provide a high brightness picture screen, by applying the slurry containing a greatly reduced amount of polyvinyl alcohol so that a high density fluorescent screen with reduced pinholes is formed.
CONSTITUTION: The amount of polyvinyl alcohol contained in the phosphor suspension is adjusted to be less than 1.8wt% when it is injected onto the panel, and the temperature is kept lower than 30°C at the injecting time of the suspension, and all over the inner surface of the panel, it is coated with the slurry with said inner surface being kept up ward. Thus, pinholes are geatly reduced and the coloring due to baking is eliminated, and the brightness can be improved.
