The regulations cover DSE, microfiches and process control screens. A European Court of Justice (ECJ) case involving a film cutter, Dietrich v Westdeutscher Runddfunk, C-11/99 [2000] ECR I-5589 ECJ, ruled that the term “graphic display screen” had to be interpreted to include screens displaying film recordings. Screens used in work with television or film pictures are therefore included.
