Abstract

PURPOSE:To enable the driving of a liquid crystal display device without using other power supplies by using the AC voltage regulated to a prescribed level as the driving voltage for respective segments of the liquid crystal display device. CONSTITUTION:The AC output voltage Vo of a power generating coil 5 is regulated to the AC voltage of the prescribed level as the voltage Vin between the cathode of a Zener diode 13 and the cathode of a Zener diode 14 is clamped to the prescribed level piE by a series circuit of a resistor 12 and the Zener diodes 13, 14. This AC voltage Vin is impressed between both electrodes of the segment 10a and the segment 10a is driven. The liquid crystal display device is thus driven by the extremely simple circuit without using the power supply such as battery.
