Abstract

A power supply circuit for driving a liquid crystal display uses the resistance characteristic of a variable resistance formed by a thermistor and a chip resistor connected in parallel to correspond to the variation of ambient temperature for adjusting the magnitude of bias voltage in driving a liquid crystal display. This appropriate bias voltage is used to adjust the contrast and density of the liquid crystal screen's pictures.
