Abstract

The invention discloses a high-transmittance touch screen, including a substrate and at least a multi-layer reflection configuration which is a four-layer structure coated on the front surface of the substrate with designed refractive index of high, low, high and low calculated from the side adjacent to the substrate, wherein the outer layer is a protection layer with protecting function provided with a reflective index laid between 1.3~1.5, a thickness of at least 0.1micrometre, and the hardness accorded with ASTM-D3363 international inspection standard, and due to the design of the protecting layer, the transmittance of the touch screen reaches ASTM-D1003 92% or more, and also strengthens the antiware performance of the surface.

Description

technical field [0001] The present invention relates to a touch screen with a multi-layer reflective structure, in particular to a capacitive touch screen with a protective layer as the surface layer of the multi-layer reflective structure to enhance the anti-wear effect. touch panel). Background technique [0002] Anti-reflective optical coatings were used in building materials such as glass and goggles in the past, but with the advancement of technology, this technology has gradually been transferred to semiconductors, optical disc read heads, liquid crystal displays, and touch panels. In the design principle of traditional anti-reflective optical coating layers, the layer coated on the contact substrate has a higher refractive index (i.e. H), and then faces this layer followed by another layer with a lower refractive index (i.e. L). Therefore, the structure of the traditional anti-reflection optical coating layer is H, L, H, L in order from the direction adjacent to the ...
