To provide a method and circuit arrangement for driving a display, in particular the display on a chip card, by means of which information optionally comprising a plurality of display images may be displayed simply and efficiently, provision is made that (a) in write mode, information to be displayed on the display which comprises at least one item of information content (display image) to be presented on the display is stored in a drive circuit associated solely with the display; (b) the ordering relationships also selectable in write mode are stored which are assigned explicitly to each of the items of information content and which determine the sequence of information contents in the event of display; (c) in read mode, the information to be displayed and comprising at least one item of information content is called up from the drive circuit and displayed on the display, wherein (d) the stored and explicitly assigned ordering relationships are taken into account with regard to the call and thus the display sequence.
A method of driving a display, in particular a display on a chip card, having the steps:
A method as claimed in one of the preceding claims, characterized in that
A circuit arrangement for driving a display, in particular a display on a chip card, characterized by a drive circuit associated solely with the display, which may be switched into write mode and read mode, wherein the drive circuits may be activated for read mode independently of a control circuit activating write mode and providing information contents to be displayed, the drive circuit comprises a non-volatile memory, wherein a first circuit unit is provided which serves in separate entry of information to be displayed, which information comprises at least one item of information content (display image) to be presented on the display, in that information contents corresponding to the information to be displayed and organization relationships assigned thereto may be stored separately, and a second circuit unit is provided which serves in reading out the information to be displayed and the assigned organization relationships, wherein the second circuit unit may be activated via a switching means.
