Abstract: A method for attaching an optical device to an encapsulated electronic package. The method may include aligning and attaching an optical device to a non-singulated encapsulated electronic package using an adhesive, and curing the entire package. The method may further include singulating the non-singulated encapsulated electronic package with the optical device attached after curing.

Abstract: A light system, such as a backlight system for an LCD, includes a light guide and an attachment structure that are insert molded together at an edge surface of the light guide, and an optically active element (e.g., an LED and/or an optical sensor) attached to the attachment structure. By insert molding the attachment structure and the light guide together at an edge surface of the light guide, the optically active element can be efficiently attached at the edge of the light guide with minimal impact on the thickness and footprint of the backlight system.
