摘要： A glass envelope (11) has its interior surface coated with phosphor by passing charged particles into the envelope. A clamp (21) includes a pair of electrically conductive members (23,25) which enclose the envelope (11) and contact its outer surface during the coating. The conductive members are supported by insulating arms (33,35) and are provided with heating elements (31) so that the temperature of the envelope is controlled and attraction of the charged phosphor particles is enhanced.

摘要： In a process for coating a substrate with phosphor particles, for example when coating phosphor particles on a fluorescent lamp glass, a polymer is deposited on the phosphor particles and the phosphor particles are entrained in a carrier gas with the polymer in a non-adhering state. The phosphor particles are then coated on the substrate with the polymer in an adhering state so as to retain the phosphor particles on the substrate. The coated substrate is then heated to a temperature above a decomposition temperature of the polymer so as to remove the polymer to form a coating of phosphor particles on the substrate.

摘要： A method for the production of a radiographic screen comprising the following steps :
1) dispersing phosphor particles in an organic liquid in the presence of a charge controlling agent that charges said phosphor particles with a positive or negative net charge,
2) arranging said dispersion between a pair of electrodes, wherein one of said electrodes is or carries a conductive support of said radiographic screen,
3) applying and maintaining between said electrodes a sufficiently high direct current voltage to deposit charged phosphor particles onto said conductive support, and

摘要： A method of manufacturing a luminescent screen assembly (22) on a substrate (18) of a CRT faceplate includes the steps of providing a coating of a non-luminescent screen structure material (23) in a predetermined pattern on the substrate, and depositing a plurality of color-emitting screen structure materials (G,B,R) on the substrate so that they are bounded by the non-luminescent material. An electrostatically-charged dry-powdered resin is:deposited onto the color-emitting and non-luminescent screen structure materials and fused to form a substantially continuous film (46).

摘要： The method of surface-treating dry-powdered phosphor particles for use in manufacturing a luminescent viewing screen (22) for a CRT (10), to control triboelectric charge characteristics of the phosphor particles, includes the steps of dissolving a suitable quantity of a polymeric coupling agent in a suitable solvent to form a mixture, surface-treating the phosphor particles by adding them to the mixture to provide a coating of the coupling agent thereon, and then drying the surface-treated phosphor particles. The resultant dry-powdered surface-treated phosphor particles are used to make the screen. The coupling agent controls the triboelectric charge characteristics of the phosphor particles during the electrophotographic manufacturing of the screen.
