Projection display device. |
| 摘要 |
<p>In a projection display device based on one or more (twisted nematic) LCDs (4), simple temperature compensation is possible by optimizing the d. DELTA n value (n) at the maximal operating temperature. The associated transmission/voltage characteristics at different temperatures then extend substantially parallel so that it is possible to compensate for temperature changes by means of a simple voltage compensation. <IMAGE></p> |
