DISPLAY TEMPERATURE COMPENSATOR FOR ELECTRIC METER ABSTRACT OF THE DISCLOSURE A display temperature compensator employs the non linear temperature coefficient of resistance of a thermistor to non linearly vary the control voltages fed to a liquid crystal display. At low temperature, substantially the entire supply voltage is available to control the liquid crystal display segments, At higher temperatures, the thermistor contracts the range of control voltages fed to the display in order that non-selected display segments remain off. A thermistor is used which has a non linear temperature coefficient of resistance which, when combined with selected fixed resistance value, substantially compensates for the non linear threshold voltage of the liquid display.
