Abstract (en)
[origin: WO2014147169A1] The invention relates to a device for exciting at least one electroluminescent pigment, in particular in a value document or security document (2), without contact, wherein the device (1) comprises at least one electrode (6), wherein the at least one electrode (6) is designed in such a way that an electric flux density of the field (7) that can be generated by the electrode (6) in a predetermined emission direction (9) changes. The invention further relates to a method for contactless excitement.
