摘要： A process for producing a light guide plate includes producing a colorless transparent sheet from a colorless transparent material by extrusion with a polishing stack. A printed reflector film is laminated in-line to the colorless transparent sheet. The printed reflector film includes: a thermoplastic reflector film which is opaque white or translucent white and made of a thermoplastic material; and a colorless thermoplastic printed on the thermoplastic reflector film. There is no direct optical contact between the colorless transparent sheet and the thermoplastic reflector film. A glass transition temperature of the printed colorless thermoplastic is above 25° C. and below glass transition temperatures of the colorless transparent material of the colorless transparent sheet and of the thermoplastic material of the thermoplastic reflector film.

摘要： The invention relates to light guide plates, which are suitable for backlighting LCD monitors as well as information and advertising signs and which are illuminated at the edges and re-emit the light fed at the edges via at least one of the two surfaces located perpendicular to the edges. For the light of a light source that is fed at the edges to be able to leave the light guide plate again via one of the surfaces by overcoming total reflection, the light rays in the light guide plate have to be deliberately deflected. At one of the two surfaces of the light guide plate, the light guide plates are provided with optical impurities (2), which are protected against damage by a film (5). Furthermore, a method for the simplified application of said impurities is provided.
