IPC: G04G9/00
Filed: 1978-07-26
Abstract: PURPOSE: To maintain the matching between a drive circuit and a liquid crystal display device by controlling the interrupting signal in response to a reduction predicting signal of a main voltage.  
     CONSTITUTION: An adjusting terminal 112 for matching the effective voltage values VON and VOFF, which are to be impressed upon a segment under the respective conditions of ON and OFF with the characteristics of a liquid crystal, is connected in advance with a potential "L" or "H" in accordance with the characteristics of the liquid crystal within the watch. If the terminal 112 is connected with the potential "L" when a main voltage reduction predicting signal is generated for the reduction in the battery voltage due the drive of an illuminator, the output of a gate 120 is selected as a RESET signal so that the pulse width of the interrupting signal becomes, e.g., 1/16. On the other hand, if the terminal 112 is at the potential "H", the outpt of an OR gate becomes the potential "H" so that the RESET signal also takes the potential "H" thereby to reduce the pulse width of the interrupting signal to zero. By reducing the pulse width of the interrupting signal in that way, the reduction in the voltage VON to be predicted by the reduction in the battery voltage can be compensated.
