    • A liquid crystal display and corresponding method are provided for reducing display image reflections off of a reflection point on an external medium (e.g. cockpit canopy or automotive windshield). A retarder is provided on the front side of the display so that the polarization direction of the display image is substantially parallel to the plane of incidence when the image reaches the reflection point. Additionally, the angle of incidence .THETA..sub.i is substantially matched to the Brewster angle .THETA..sub.p in order to maximize the reduction of reflection at the reflection point. The retarder has a retardation value of from about 220-320 nm according to certain embodiments, and is a 1/2 .lambda. retarder according to preferred embodiments.
    • 提供了一种用于减少外部介质(例如驾驶舱罩或汽车挡风玻璃)上的反射点的显示图像反射的液晶显示器和相应方法。 在显示器的前侧设置有延迟器,使得当图像到达反射点时,显示图像的偏振方向基本上平行于入射平面。 此外,入射角THETA i基本上与布鲁斯特角度THETA p相匹配,以便最大程度地减少反射点处的反射。 根据某些实施方案,缓凝剂具有约220-320nm的延迟值,并且是根据优选实施方案的+ E,fra 1/2 + EEλ延迟剂。
