CATHODE RAY TUBE FACE PLATE CONSTRUCTION FOR SUPPRESSING THE HALO AND METHOD Abstract of the Disclosure Cathode ray tube face plate construction for suppressing the halo on the cathode ray tube having a face plate formed of glass with an index of refraction in the vicinity of 1.52 and with outside and inside surfaces. A fluorescent phosphor screen is carried by the inside surface. An optional metallic coating overlies the phosphor screen on the side of the screen facing away from the face plate. An anti-reflection coating is carried by the outside surface of the face plate for reducing reflection from the outside surface of the face plate to suppress the central portion of the halo. A thin film interfer- ence coating is carried by the inside surface of the face plate for suppressing the outer ring-like portion of the halo. It is disposed between the phosphor screen and the inside surface of the face plate. The thin film inter- ference coating has high transmittance for light emitted by the phosphor at near normal of incidence and high reflectance at high angle of incidence.
