Abstract (en)

[origin: EP0148530A1] A cathode ray tube faceplate arrangement including a halo suppression layer (32) disposed between a faceplate (14) and a thin film luminescent screen (16) having a light scattering surface (20). The halo suppression layer has a refractive index which is smaller than that of the faceplate and the screen and which reflects toward the scattering surface part of the rays of luminescent radiation which would otherwise contribute to halo.
