Absorbing anti-reflection coatings for computer displays |
摘要 |
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 SiO2; H, a high refractive index material such as the metal oxide Nb2O5; 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 </=0.6%.
