Polarization-Independent Liquid Crystal Display Devices Including Multiple Polarization Grating Arrangements and Related Devices
摘要：
A liquid crystal device includes a first polarization grating (101), a second polarization grating (102), and a liquid crystal layer (103). The first polarization grating (101) is configured to polarize and diffract incident light (190) into first and second beams (195,196) having different polarizations and different directions of propagation relative to that of the incident light (190). The liquid crystal layer (103) is configured to receive the first and second beams (195,196) from the first polarization grating (101). The liquid crystal layer (103) is configured to be switched between a first state that does not substantially affect respective polarizations of the first and second beams (195,196) traveling therethrough, and a second state that alters the respective polarizations of the first and second beams (195,196) traveling therethrough. The second polarization grating (102) is configured to analyze and diffract the first and second beams (195,196) from the liquid crystal layer (103) to alter the different directions of propagation thereof in response to the state of the liquid crystal layer (103). Related devices are also discussed.
摘要（中）：

液晶装置包括第一偏振光栅（101），第二偏振光栅（102）和液晶层（103）。 第一偏振光栅（101）被配置为将入射光（190）偏振并衍射成具有不同偏振和不同传播方向的第一和第二光束（195,196）相对于入射光（190）的偏振方向。 液晶层（103）被配置为从第一偏振光栅（101）接收第一和第二光束（195,196）。 液晶层（103）被配置为在基本上不影响穿过其中的第一和第二光束（195,196）的相应极化的第一状态之间切换，并且改变第一和第二光束的各自偏振的第二状态 （195,196）。 第二偏振光栅（102）被配置为响应于液晶层（103）的状态来分析和衍射来自液晶层（103）的第一和第二光束（195,196），以改变其不同的传播方向， 。 还讨论了相关设备。
