METHOD FOR COATING LIGHT-EMITTING DEVICES, LIGHT COUPLER, AND METHOD FOR MANUFACTURING THE LIGHT COUPLER

摘要

The invention relates to a method for coating light-emitting devices, comprising the steps of: providing a plurality of light-emitting devices; applying a first photo-curable liquid onto the plurality of light-emitting devices; selectively exposing the first photo-curable liquid to a first light to form a first coating layer on at least a portion of the surfaces of the light-emitting devices; applying a second photo-curable liquid onto the plurality of light-emitting devices on which said first coating layer is formed; selectively exposing the second photo-curable liquid to a second light to form a second coating layer on at least a portion of the surfaces of the light-emitting devices or on at least a portion of the surface of the first coating layer. The first coating layer is equivalent to the hardened first photo-curable liquid, and the second coating layer is equivalent to the hardened second photo-curable liquid.
