Display device made up of segments.

摘要

In a display device made up of segments (A-H) by applying drive signals to selected segments fixedly associated with the particular valid character to be represented via segment drive lines (a1-h1, a2-h2) connected to the segments characters of a predetermined subset of valid characters from a representable total set are displayed. Each segment is connected to a first segment drive line (a1-h1) and to a second segment drive line (a2-h2) and a segment becoming visible only when a drive signal is applied to both segment drive lines connected to the segment. The first segment drive lines of a plurality of first segment groups are connected together and form first group drive lines (S1-S4). The second segment drive lines (a2-h2) of a plurality of segment groups are likewise connected together and form second group drive lines (COM1, COM2). The segments for forming the segment groups are selected in such a manner that on interruption of one or more group drive lines and on application of the drive signals for representing a character no other character of the predetermined sub set of valid characters is displayed.
