Liquid crystal display device having capacitance compensation

摘要

A display apparatus having a liquid crystal display is provided with a measuring element for controlling the drive voltages depending on the temperature of the liquid crystal. The effect of manufacturing tolerances and ageing phenomena are compensated for by means of an auxiliary measuring element. The electric voltages across the measuring element and the auxiliary measuring element differ from one another, for the adjustment of mutually different operating points on the capacitance-voltage curve.
