Patent ID: 10756298

Abstract:
An OLED device comprising a substrate with a top surface; a first electrode covering the top surface of the substrate; a first insulating structure patterned over a portion of the first electrode where the pattern defines an inside area of the first electrode that is completely surrounded by the insulating structure, and an outside area of the first electrode not covered by the insulating structure; at least one organic layer for light emission within the inside area defined by the insulating structure; a second electrode over the at least one organic layer within the inside area defined by the insulating structure and at least partially over the first insulating structure; a cover slip located at least over the second electrode in the inside area defined by the insulating structure; and an electrically conductive solder seal making a hermetic seal between the insulating structure and the cover slip where the solder seal is in electrical contact with the second electrode. The insulating structure is desirably made of glass frit.
