METHOD AND APPARATUS FOR COUPLING LIGHT-EMITTING ELEMENTS WITH LIGHT-CONVERTING MATERIAL

摘要

Light-emitting elements such as LEDs (714) are associated with light- converting material such as phosphor and/or other material. A donor substrate (720) comprising the light-converting and/or other material (726) is suitably placed relative to a target substrate associated with the light-emitting elements. A laser (730) or other energy source is then used to transfer the light-converting and/or other material in a pattern (738) via writing or masking from the donor substrate to the target substrate in accordance with the pattern. Addressability and targetability of the transfer process facilitates precise patterning of the target substrate.
