    • The liquid crystal switchable color filter switches between three color bands and is preferably used for time-sequential color devices, as for example projection devices, direct view displays and video cameras. The color filter employs circularly polarizing selective reflection bands of at least four cholesteric filters (89, 91, 93, 95) together with three liquid crystal switches (81, 83, 85) and related retarder layers. Between the first and the second as well as between the third and the fourth cholesteric filter an additional half-wave plate (111, 113) is provided, which makes it possible to use cholesteric filters having all the same handedness. Furthermore, for the blocking state of a color band the optic axis of the corresponding liquid crystal switch is parallel or perpendicular to the polarization direction. This concept simplifies production and still exhibits excellent properties for the color switch. Moreover, it advantageously allows overlapping color transmission bands thus improving the light efficiency.
    • 液晶可切换彩色滤光片在三个色带之间切换,并且优选用于时序彩色装置,例如投影装置,直视图和摄像机。 滤色器与三个液晶开关(81,83,85)和相关的延迟器层一起使用至少四个胆甾醇滤光器(89,91,93,95)的圆偏振选择反射带。 在第一和第二之间以及在第三和第四胆甾醇型滤光器之间,提供了附加的半波片(111,113),这使得可以使用具有相同的手感度的胆甾型滤光器。 此外,对于色带的阻挡状态,相应液晶开关的光轴平行或垂直于偏振方向。 该概念简化了生产,并且对于颜色开关仍然表现出优异的性能。 此外,其有利地允许重叠的彩色传输频带,从而提高光效率。
