Abstract
A voltage stabilizer receiver power from a power circuit for inputting a power source voltage. The voltage stabilizer changes the width of pulses in accordance with the changes in the effective value of the power source voltage and stabilizes the effective value of an applied voltage to a display regardless of the change in the effective value of the power source voltage by subtracting this pulse from pulses comprising the display drive waveforms.
