Abstract
PURPOSE: To ensure a compact and light-weight structure for the circuit with reduced power consumption by securing the indicator driving system through the dynamic driving for the liquid crytal.
CONSTITUTION: A synchronization is secured between digit selection repetitive pulse generator 42 and segment selection pulse generator 43 via the pulses generated from timing pulse generator 41, and then the numerical information is introduced to generator 43 from shift register 44. The digit signal sent from generator 42 is introduced to desired digit electrode 45, and at the same time the segment signal is introduced to segment electrode 46 from generator 43 to secure the display of desired figures. Thus, the desired figures are displayed for electrode 45. In such way, the circuit constitution or the wiring can be simplified for the display of the desired figures. Thus, a compact and light-weight structure can be secured with reduced power consumption.
