Abstract: An integrated circuit card contains a liquid crystal display for displaying at least a portion of the information stored therein. The displayed information is stored in a first, or reserved, memory. A second, or additional, memory is used to store further information. The use of a reserved memory for storing the displayed information permits the use of very low power electrical energy sources for driving the display and the electronics controlling the pixels of the display, such as piezoelectric sources, pyroelectric sources, photovoltaic cells, and very small batteries. The first and second memories may be integrated into a single IC chip, or they may be separate components.
