  • Method for manufacturing a transparent element with invisible electrodes
    Patent number: 7247568
    Abstract: A conductive pattern, made of a transparent conductive oxide, such as ITO including electrodes (2) and conductive paths (4) is formed on one face of a transparent substrate (3) made of sapphire or toughened glass, then coated with a first layer (5) of a transparent dielectric with a low refractive index, such as MgF2 or LiF2, and then a second layer (7) of another transparent dielectric having a higher refractive index than the first, such as Al2O3, Ta2O5 or DLC.
