Patent ID: 6958748

Claim:
Transparent baseboard with conductive multi-layer antireflection films on a transparent substrate, including the transparent substrate, a conductive third layer of transparent thin film, and transparent dielectric multi-layer thin films in between, wherein refractive index of said substrate is between 1.48 and 1.70, and said transparent dielectric multi-layer thin films form first- and second-layer thin films, wherein the first layer has refractive index between 1.50 and 2.50 that is higher than said substrate, the second layer films thin film has refractive index between 1.35 and 1.60 that is lower than said substrate, the thickness of the conductive layer is determined with desired surface resistance, the optical thickness of the first and the second-layer thin films satisfies the theoretical view-sense reflection index less than a proper value by varying their desired thickness taking into account refraction indexes of the substrate and the first- and the second-layer thin films, and the optical thickness of the first-layer thin film is not λ/4 and the sum optical thickness of the second-layer thin film and the conductive layer is not λ/4.
