1 PHN 9310 ABSTRACT: In a display apparatus having a liquid cry- stal display, provided with a measuring element for controlling the drive voltages depending on the temper- ature of the liquid crystal. The effect of manufactur- ing tolerances and ageing phenomena are compensated for by means of an auxiliary measuring element. The elec- tric voltages across the measuring element and the aux- iliary measuring element differing from one another, for the adjustment of mutually different operating points on the capacitance-voltage curve.
