Method for forming a phosphor screen of a cathode ray tube.

摘要

Method for a phosphor screen of a cathode ray tube includes the steps of forming a photo-tacky layer on a panel of a cathode ray tube, exposing the photo-tacky layer to form an adhesive pattern on the layer, and adhering phosphor powder on the adhesive pattern, in which these exposing and adhering steps are repeated. Before the next exposing step, the photo-tacky layer is heated and then exposed after cooling. The heating step prevents the sensitivity of the layer from deterioration caused by the preceding adhering step.
