摘要:
The invention comprises devices and methods for coupling a light source to a display illumination device. In one embodiment, an illumination device includes a light guide comprising a front surface, a back surface, a light coupling section configured to receive optical energy from a light source in to the light guide through said front surface or said back surface at an angle about normal to the optical energy receiving surface, and further configured to direct light through said light guide, and a light turning section configured to redirect out of the light guide at least a portion of the light received from said light coupling section, said redirected light at an angle about normal to the optical energy receiving surface.
