Zusammenfassung:	Systems, devices, and methods are provided for using a textured surface of a light guide plate to reduce friction between the light guide plate and an adjacent film. A textured surface across an interior region of the light guide may guide light towards a top surface of the textured light guide. A film positioned on the bottom surface of the textured light guide may reflect light towards the top surface. The film may be positioned within the interior region as a substantially flat (e.g., planar) layer. The surface features may reduce the friction to enable the textured light guide plate and/or film to expand or contract independently from one another due to varying temperatures without forming wrinkles on the film or changing the planarity of the film.
