DISPLAY DEVICE HAVING A LIQUID CRYSTAL |
| 摘要 |
<p>1 PHN 9310 In a display apparatus having a liquid crystal display, 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 differing from one another, for the adjustment of mutually different operating points on the capacitance-voltage curve.</p> |
