Transparent substrate, transparent conductive element and optical device containing the same

Abstract

A transparent base material comprises a body and a micro-nano structure formed on one surface of the body. The body is a transparent substrate. The micro-nano structure comprises a plurality of nanoscale protrusions, the protrusions are distributed on the surface of the body in an interval mode, the structural size of each protrusion is smaller than visible light wavelength, so that the protrusion structure cannot be recognized by light waves, therefore, the refractive index of the surfaces of the protrusions changes in a continuous gradient mode, and the reflex phenomenon caused by sharp change of the refractive index can be reduced. The micro-nano structure has good optical reflex reduction effects. When one side, with the micro-nano structure, of the transparent base material is contacted with another optical element in a stacking mode, due to the fact that a micro-nano structure array is of a concave-convex structure and the structure is compact, reflection rays among air clearances will not interfere mutually when contact occurs, and therefore a Newton ring phenomenon can be effectively reduced. The invention further provided a transparent conducting element and an optical device containing the transparent base material.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a transparent substrate, a transparent conductive element and an optical device containing the transparent substrate. Background technique [0002] The touch screen is an input device that significantly improves the man-machine interface, and has the advantages of intuition, simplicity and speed. Touch screens have been widely used in many electronic products, such as mobile phones, PDAs (Personal Digital Assistants), multimedia, and public information inquiry systems. [0003] The touch screen is usually composed of panel glass and conductive glass components bonded by transparent optical glue. The conductive glass assembly is coated with a transparent conductive layer on one side of the glass substrate. When light passes through a transparent material, due to the refraction and reflection of light, the light that finally passes through the transparent material suffers a cert...

AI Technical Summary

Problems solved by technology

Due to the large difference between the refractive index of the transparent conductive layer and the glass, the light will be reflected and refracted at the interface between the two. Therefore, the transmittance of the touch screen will further decrease, which will affect the transmission of light.
