1. A device for providing backlighting or front-lighting to a display panel, the device comprising:
- a light emitting panel having an emitting face, a rear face, and an edge;
the light emitting panel including at least one light interface for receiving light from a light source spaced apart from the light emitting panel, the light interface defining a light interface aperture that is configured to at least partially receive a portion of the light source therein;
the light interface aperture defining a semi-circular notch or groove; and
at least one guiding member for aligning the light source within the light interface aperture, said at least one guiding member including one or more ribs extending inwardly within the semi-circular notch or groove.

Abstract
Devices and assemblies for providing light to a display panel, including methods of attaching such devices and assemblies to a circuit board, are disclosed. An illustrative device can include a light emitting panel including at least one light interface for receiving light from a light source. The light interface may define an aperture adapted to receive a portion of the light source, forming an air gap between the light source and interface. A number of centering ribs and/or beveled sections can be used to align the light source within the aperture during assembly of the device to a circuit board.
