    Abstract: A glare-reducing coating, as for a viewing surface of a cathode-ray tube, is prepared by (a) warming the surface of a support to about 30 DEG to 100 DEG C, (b) coating the warm surface with an aqueous solution containing a lithium stabilized silica sol, (c) drying the coating, (d) baking the dry coating at about 150 DEG to 450 DEG C, and then (e) subsequent to said heating step (d), washing the dry coating with hot water. The coating may contain carbon particles or carbon particles and a color-correcting dye.

    Abstract: A cathode-ray tube including, on its viewing surface, a glare-reducing coating composed of a lithium silicate material and carbon particles. The novel method comprises: (a) warming the surface of a glass support to about 30 DEG to 100 DEG C, (b) coating the warm surface with an aqueous solution containing about 1 to 10 weight percent of a lithium-stabilized silica sol and a sufficient proportion of carbon particles to produce the desired reduction in light transmission, (c) drying the coating, and then (d) heating the dry coating at about 150 DEG C to 300 DEG C.

    Abstract: A CRT comprising a screen support, a luminescent viewing screen on the support, a light-reflective metal layer on the screen, and a particulate layer of carbon particles and preformed silica particles on the metal layer. The particulate layer may be made by spraying a suspension of carbon (amorphous carbon and/or graphite) and silica (less than 0.1-micron size) on the metal layer while it is preheated in the 50 DEG to 75 DEG C. range.

    Abstract: A cathode-ray tube comprising a glass viewing window having, on its external viewing surface, an antistatic, glare-reducing, image-transmitting coating. The coating has a rough surface and is composed essentially of a silicate material and a metallic compound in proportions to impart the desired antistatic characteristic without substantially degrading the image-transmitting capability of the coating. When the tube is operated, the coating is grounded either directly or through the metal implosion-prevention system on the tube.
