Abstract
An absorbing anti-reflection coating which can be applied directly to the faceplate of a video display such as a cathode ray tube or a plasma display by physical or chemical vapor deposition comprises at least 3 materials: L, a low retractive index material such as the metal oxide SiO.sub.2 ; H, a high refractive index material such as the metal oxide Nb.sub.2 O.sub.5 ; and M, a metal or metallic alloy or metallic compound layer with a refractive index greater than 0.5 and extinction coefficient less than 5. Preferably the materials are used in the design MHLHL or HMHL. The design and materials provide broadband performance with a low layer count. The single metal layer design permits relatively low values of sheet resistance (high conductivity). Transmittance values are high, typically 70%.+-.5%. Reflectance typically is .ltoreq.0.6%.
