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.

Effective value voltage stabilizer for a display apparatus

A circuit for driving a display of an electronic apparatus including first supply means for applying a power source voltage E to at least one selected picture element during a display period to display it and for applying each of a first voltage V.sub.1 and a second voltage V.sub.2 to said at least one selected picture element for each half interval during a non-display period, and second supply means for applying the zero voltage to at least one non-selected picture element during the display period to erase it and for applying each of the first voltage V.sub.1 and the second voltage V.sub.2 to said at least one non-selected picture element for each half interval during the non-display period, where

Timesharing driver for liquid crystal display device

This invention relates to a thermometry device which measures temperature using an electronic calculator system. The device includes a resistor whose resistance value varies depending upon temperature, an oscillator providing a wave-form oscillating at a frequency which is dependent upon temperature, a clock generator providing reference clock pulses and a counter for counting the clock pulses within a length of time as defined by the frequency of the waveform divided by a factor. Temperature-related information is obtained from the results of the counting.
