Abstract
In one aspect, a light emitting device comprises a light source, a film-based lightguide with a light emitting region. The film may have a light mixing region positioned between a light input region and the light emitting region. In one aspect a ratio of a length of the light mixing region to a length of the light emitting region is greater than 0.1 in a first plane comprising the thickness direction. In one aspect the light emitting device comprises a guide element having a surface curved in a first plane positioned adjacent the inner surface of the film, wherein the film is folded along the curved surface at a first fold such that the first fold positions a portion of the light mixing region above or below the active area of the display and the light mixing region comprises the first fold.
