Transparent board with conductive multi-layer antireflection films, transparent touch panel using this transparent board with multi-layer antireflection films, and electronic equipment with this transparent touch panel

Transparent touch panel including

• a transparent fix substrate with a third thin film of transparent dielectric,
• a transparent flexible substrate with a third transparent conductive layer thin film situated away from said fix substrate,
• wherein these conductive third thin films are electrically connected to external circuits,
• and at least one of said transparent fix substrate or said transparent flexible substrate has a refraction index between 1.48 and 1.7,
• and multiple layers of dielectric thin films are sandwiched between said transparent fix substrate or said transparent flexible substrate and said third-layer thin film,
• comprising the conductive anti-reflection film formed with the manner that firstly said dielectric thin films are laid on the substrate and secondly said third thin film is laid, in which the first-layer transparent thin film has refraction index between 1.50 and 2.50 that is higher than said selected transparent fix substrate and/or flexible transparent substrate, and the second-layer transparent thin film with refraction index between 1.35 and 1.60 that is lower than said selected transparent fix substrate or flexible transparent substrate.

A method of making a transparent baseboard with conductive multi-layer antireflection films on a transparent substrate comprising the steps of:

• determining the thickness of the most exterior surface to provide the best surface resistance according to the application of the transparent baseboard;
• growing a first layer of anti-reflection film on the substrate in which the refractive index of the first layer is between 1.50 and 2.50, and the refractive index is higher than a refractive index of the substrate, determining a thickness of the first layer by using a coarse optimum value approximately 0.2 to 0.3 away from the genuine optimum in the view-sense reflection index;
• and
• growing a second layer of anti-reflection film on the substrate in which the refractive index of the first layer is between 1.35 and 1.60, and the refractive index is lower than the refractive index of the substrate, determining a thickness of the second layer by using a coarse optimum value approximately 0.2 to 0.3 away from the genuine optimum in the view-sense reflection index.
