Display temperature compensator for electric meter

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 seg...
