Abstract
PURPOSE: To increase the illumination brightness of fluorescent film, by increasing the adhesive strangth of the fluorescent substance dot, through the formation of the organic precoat film internal the face plate preheated at a high temperature.
CONSTITUTION: The precoat liquid including at least one type of emulsion such as acryl, polystylene and methylmetacrylate is blown on the internal surface of the face plate preheated and coated. Since the organic precoat film material in spray state is solidified when it contacts with the preheated face plate, it does not form smooth film shape but is formed uneven, and since the film is hard, fine cracks are developed after drying, and the strength for attaching is increased in coating the fluorescent slurry coating at the next process. This precoat is removed with the baking process and the fluorescent substance and the aluminum film are left.
