Abstract: A headset for augmented reality applications is provided. The headset includes at least one eyepiece configured to provide a see-through image to a user via a transparent optical component, and to provide an artificial image through a display, and a dimming shutter configured to adjust a transparency level of the transparent optical component. The dimming shutter further includes an active liquid crystal layer configured to adjust a transparency level according to an electrical power provided between two electrodes, and a photoactive layer configured to adjust the transparency level upon absorption of an ultraviolet radiation for a selected period of time. A default orientation of a host material in the active liquid crystal layer may be in a dark state or in a clear state, when no electrical power is provided. A method and a memory storing instructions to execute the method for use of the above device are also provided.

Abstract: 本发明涉及一种温度自适应液晶组合物及应用其的液晶调光器件，其液晶组合物包括向列相液晶组合物、负温度敏感性手性组合物以及双介晶组合物。本申请中的负温度敏感性手性组合物随温度升高具有较大的负波长偏移量，为提高其稳定性，可通过进一步复合低温度敏感性手性化合物进行螺距调节，使得选择性反射波长能自动调节至所需波段范围，通过加入具有低螺旋扭曲能力的双介晶组合物，进行弹性常数调节，扩展波长偏移量，最终实现液晶调光器件对外界光线具有较大的负波长偏移量和较高的反射率，从而实现对室内温度的自适应调节。

Abstract: 本发明提供一种含可聚合化合物的液晶组合物及其应用，包含通式（I）所代表的可聚合化合物中的一种或多种，及向列相液晶组合物。本发明通过在向列相液晶组合物中引入含有三个可聚合基团的反应性介晶(RM)，三个可聚合基团可以加快反应速度时间，降低制程时间，使得液晶组合物的配向效果更好，聚合更完全，残留更低，并且能有效改善液晶组合物的低温互溶性，降低成角时间。特别是对于现有PSVA液晶来说，在对其他参数没有明显损害的情况下，能缩短在测试盒中可测量的预倾斜相关的响应时间，具有重要的应用价值。
