A process for the preparation of a flat or in a direction of the filament material umbrella curved for flat color screens - and - image display equipment

摘要

the leuchtstoffaufbringung several colors, for example, the three colors red, green and blue on the substrate serves as plane or in a direction gekruemmte schirmglas is effected by means of an doppelmasken - rasterbeschichtungsverfahrens in several, e.g.three successive steps, and at each step of the flaechenaussparungen all paints containing the basic display and each with the flaechenaussparungen for the corresponding color beschichtungsmaske shall be used.the advantages of the technology compared with the known methods, the photo are the following: optimal farbreinheit, no unregelmaessigkeiten by washing or mehrfachbeschichtung, better particle size distribution, increase the flaechenbelegung with phosphorus, no mechanical load on the remaining leuchtpigmente by washing.not high, prevent material in relation to leuchtstoffverbrauch, better adhesion by spruehtechnik. transistors are built.
