Surface treatment of phosphor particles and method for a CRT screen. |
摘要 |
<p>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.</p> |
