Abstract (en)
The present invention provides an electric shielding and anti-glaring multi-layer coating for cathode ray tube, and the method for making the same. A plurality of sputtering layers are formed on the outer surface of the glass panel of the CRT. An anti-glaring layer is formed on the outer surface of the sputtering layers by spraying. The plurality of sputtering layers contains conductive material such as ITO and having a protective layer to protect the conductive layer from acid corrosion. The multi-layer coating also has anti-reflection property in wide spectral range, and also has good hardness and resistance to fingerprint. <IMAGE>
