1. a method of making cathode tube is characterized in that comprising the following steps:

  • Outside surface with the solution coating panel that contains electro-conductive material carries out drying with coated panel, forms conductive film on this panel;

    Non-glare coating compostion is coated on the described conductive film, on described conductive film, to form protective membrane, described non-glare coating compostion is to be that to contain volume ratio be 20;

    80 to 80;

    20 the tetraethyl silicate monomer and the hybrid silicic acid fat of ethyl polysilicate tetramer by add 1 to 20% weight in the solution that contains 55 to 95% weight alcoholic solvents or polar solvent, 1-3% weight acid catalyst and 3 to 20% weight water on the basis of 100% weight at described synthetics, be hydrolyzed then, carry out polycondensation again and obtain;

    WithCure described conductive film and described protective membrane simultaneously, thereby form individual layer.
