Definitions

  • the inside of the window is treated, for example, with a 15% solution of polyvinyl-carbazol in parts of chlorobenzene and 1 part of dichloromethane.
  • polyvinylcarbazol may be used a variety of organic film-forming polymers having good dielectric properties.
  • Luminescent dots 2 are present on a window 1.
  • the intermediate spaces of the window 1 are provided with a conductive layer 3 on which a dielectric layer 4 is present.
  • the picture screen is now exposed to a positive or negative corona discharge.
  • a method of manufacturing a luminescent screen for a color display cathode ray tube comprising a transparent substrate and discrete areas of electronexcitable color luminescent materials disposed thereon and separated by a light absorbing material, said method comprising the steps of:
  • each one of said first and second solutions has a concentration of said ionogenic material and said dielectric material, respectively, not exceeding 10%.
