Various driving method for liquid crystal hands to display simultaneously three timekeerping parameters, e. g., hour, minute and second, are proposed in this paper. They are evaluated by the driving margin and complexity of driving circuit respectively. The driving margin in these method attains to 1. 9, and this value is large enough for practical use. The large margin and the simple circuit are achieved by "DYNAMIC DRIVE" method. The large margin and the low applied voltage are achieved by "STATIC MULTIPLEX" method or "MULTI SCANNING" method. Further, newly developed driving wave forms for the bargraph displays and the time dial displays afe proposed. Thus, LC clocks with three hands and bargraph displays are realized.
