Title:
OPTICAL FILM, ITO FILM, AND TOUCH-CONTROL SCREEN AND METHOD FOR FABRICATING OPTICAL FILM
Document Type and Number:
WIPO Patent Application WO/2019/109618
Kind Code:
A1
Abstract:
The present invention provides an optical film, an indium tin oxide (ITO) film, and a touch-control screen and a method for fabricating an optical film; said optical film contains a first hardened layer and a transparent substrate layer; said transparent substrate layer contains a first optical surface and a second optical surface; said first hardened layer is arranged on the first optical surface of the transparent substrate layer; the first hardened layer contains two or more refractive index materials; no apparent delamination is present in the first hardened layer; such a design effectively prevents interference fringes in the first hardened layer as a result of the stratification of different refractive indexes; in combination with the progressively decreasing distributed arrangement of refractive indexes in the technical solution, a particularly good anti-reflective effect is produced, the purpose of which is to eliminate the etch marks that appear after subsequent ITO etching.
