ABSTRACT:
An electro-optical time-indicating system displays the time by simulating a clock using dial hands. The electrodes of a liquid crystal display are formed by radial track segments and the backing electrodes are subdivided into inner and outer electrodes. The driving of the track segments to indicate hours, minutes and seconds is accomplished by a time division multiplex technique. In order to keep the number of electrode terminals for the track segments to a minimum, the track segments are combined into L track segment cascades with L input terminals. The track segments are arranged in K twin sets such that, as viewed in the clockwise direction, an n.sup.th track segment (where n ranges from 1 to L) of one set of the twin sets is always connected with the L+1-n.sup.th track segment of the other set of a twin set. The inner backing electrodes are subdivided into M inner blocks with one terminal each, and the outer backing electrodes are divided into N outer blocks with one terminal each. Each twin set is covered by two adjacent inner blocks and two adjacent outer blocks. The time-functional drive of the terminals of the track segment cascades takes place alternatingly in ascending and in descending order, and successive terminals of the inner and outer blocks are energized in a clockwise direction after every change-over between ascending and descending drive.
