Method and device for manufacturing broadband cholesteric polarizer

本申请描述了用于制造很好确定了带宽和边缘位置的宽带偏振器的方法和装置。为了这个目的，通过暴露于辐射将包括具有不同反应性的反应性手性单体和反应性线形单体的液晶胆甾有序层聚合。本发明的特征在于：当到达该频带的所需边缘位置时，显著地增大辐射强度，优选10或更多倍。结果，在该时间达到的该反射带的带宽和边缘位置就象是被冻结了。可以使用单色光传感器测定所述位置是否达到，该传感器所用的波长相当于该频带所需边缘位置的波长。可以将具有很好确定了带宽和边缘位置的宽带胆甾偏振器非常有利地用于显示器。 The Application describes a method and devices for manufac...
