METHOD FOR FABRICATING A DISPLAY DIAL FOR A PORTABLE OBJECT SUCH AS A TIMEPIECE AND DISPLAY DIAL OBTAINED THEREBY

摘要

Method for fabricating a transparent display dial for a portable object, wherein the method includes the steps of:
creating a mould with a first relief pattern for imprinting a decoration on at least a first portion of the surface of the transparent display dial, and with a second relief pattern for imprinting an antireflective filter on a second portion of the surface of the transparent display dial;depositing on the dial a mixed layer of a monomer and a cross-linking agent sensitive to ultraviolet radiation;applying the mould on the mixed monomer and cross-linking agent layer;solidifying the mixed monomer and cross-linking agent layer by photopolymerization under ultraviolet irradiation through the mould, andafter insolation, removing the mould.;The invention also concerns a transparent display dial obtained according to the method of the invention.

1. A method for fabricating a transparent display dial for a portable object, wherein the method comprises the steps of:
creating a mould bearing a cavity or footprint formed of a first relief or 3D pattern for imprinting a decoration on at least a first portion of the surface of the transparent display dial, and of a second relief or 3D pattern for imprinting an antireflective filter on a second portion of the surface of the transparent display dial; depositing on the dial a mixed layer of a monomer and a cross-linking agent sensitive to ultraviolet radiation; applying the cavity of the mould on the mixed monomer and cross-linking agent layer; solidifying the mixed monomer and cross-linking agent layer by photopolymerization under ultraviolet irradiation through the mould, and after insolation, removing the mould.
