    摘要: In order to form a screen layer having less color fogging and coating unevenness in the course of production of a cathode-ray tube, a panel inner surface having a carbon layer (6) formed thereon is precoated with a solution of a nonionic surfactant (e.g., polyoxyethylene sorbitan fatty acid ester), and a phosphor layer (3) is formed on the panel inner surface (2).

    摘要: To form a plurality of stripe-like phosphor layers on a surface of a substrate in forming a plasma display panel, the surface having a plurality of parallel ribs disposed thereon and grooves defined between pairs of adjacent ribs, the following steps are carried out: providing a filamentary body formed from a phosphor paste composed of a phosphor substance and a first synthetic resin; placing a moulded filamentary body in each groove; filling the grooves with a solvent optionally containing a second synthetic resin compatible with the first synthetic resin; and conducting a sintering treatment of the substrate to form the phosphor layers in the grooves. An apparatus for this purpose has a mounting base (51) for mounting thereon a substrate (21) having a plurality of parallel ribs (r) disposed thereon and grooves (g) defined between pairs of adjacent ribs, and a supplier (53) for supplying a filamentary body (54) into the grooves, the filamentary body being made of a phosphor substance and a synthetic resin.

    摘要: A dispersion solution of colloidal silica is coated on a pigment layer of a substrate composing a filter layer and then dried. Accordingly, the state of the front surface of the filter layer (pigment layer) is controlled without affecting the filter layer (pigment layer). A phosphor layer is formed on the filter layer (pigment layer). The method has application to phosphor screens in cathode ray tubes and plasma display panels for improving their uniformity of brightness and contrast.

    摘要: A process for the preparation of an image is provided, which comprises exposing to light a layer of a composition which changes its stickiness when irradiated with active light, spraying a particulate image-forming material on to the layer, removing the particulate matter which has not been attached to the layer, and then heating the layer to fix the particulate image-forming to the substrate. This process is suitable for the patterning of not only a fluorescent substance for plasma display but also a light-impermeable or sparingly light-permeable material to which photolithography has heretofore been difficultly applied. Furthermore, the thickness of the image-forming material layer can be easily varied by properly selecting the grain diameter of the image-forming material.
