Abstract
A method of manufacturing a film assembly comprises forming a film-based lightguide with a lightguide region, adding a layer comprising linear light turning features to the film-based lightguide while it is moving in a web direction such that the linear light turning features are oriented in the web direction of the film-based lightguide, and cutting the film-based lightguide while it is moving in a web direction in a plurality of linear sections, the plurality of linear sections comprises linear sections that define lateral edges a light emitting region and/or lateral edges of coupling lightguides extending from the lightguide region, wherein the linear sections are cut at first cut angle between 3 degrees and 25 degrees to a transverse direction of the film-based lightguide orthogonal to the web direction and the thickness direction.
