发明名称 Cipkarte mit bistabiler Anzeige
摘要 The invention relates to a chip card comprising a ferroelectric liquid crystal display. The liquid crystals contain at least one mesogene compound. Such mesogene compounds include a nodal structure comprised of at least two cyclical compounds and one or two side-chains. At least one mesogene compound presents one or more partly fluorinated or perfluorinated side-chains. The inventive chip card is particularly suited to practical application since the display can be connected at voltages </=15 V, preferably </=5 V. The chip card is recordable within a broad temperature range and is particularly resistant to daily stresses such as pressure, bending or thermal deformation
