Abstract: A liquid crystal display system having improved temperature compensation using multiple capacitance ratios for different display temperature ranges. The capacitance of a liquid crystal display segment is measured when preconditioned to a first voltage below the threshold voltage and when preconditioned to a second voltage above the threshold voltage. Separate embodiments are disclosed which sequentially measure the capacitance of a single segment or which simultaneously measures the capacitance of two segments. The magnitude of the second voltage is adjusted to converge the ratio of the measured capacitances to a predetermined value selected according to the display temperature. The on segment and off segment voltages are then formed based on fixed percentages of this second voltage.
