该液晶显示面板11包括第一偏光板102、液晶层104、阵列基板103以及彩膜基板105；第一偏光板102用于将背光模块的出射光线101转换为线偏振光；液晶层104用于对第一偏光板102出射的线偏振光进行旋光操作；阵列基板103用于控制液晶层104中的液晶分子的偏转角度，以控制线偏振光的旋光角度；彩膜基板105用于将线偏振光转换为具有显示色彩的线偏振光。
偏光眼镜12包括第二偏光板106，第二偏光板106用于将液晶显示面板11的出射光线转换为显示光线，其中偏光眼镜12显示液晶显示面板11的显示画面时，第二偏光板106的偏光轴的方向与第一偏光板102的偏光轴的方向垂直。
本优选实施例的液晶显示系统10使用时，背光模块产生出射光线101，该出射光线101为非偏振光。出射光线101通过液晶显示面板11的第一偏光板102后，转换为线偏振光，该线偏振光的偏振方向与第一偏光板102的偏光轴的方向相同。随后线偏振光通过液晶显示面板11的液晶层104进行旋光操作，具体的旋光角度根据液晶层104中的液晶分子的偏转角度确定（该液晶分子通过阵列基板103上的像素电极进行驱动），从而可通过不同旋光角度的线偏振光来表示液晶显示面板11的显示内容。最后通过彩膜基板105上的彩膜色阻以及黑色矩阵将线偏振光转换为具有显示色彩的线偏振光。这时由于并没有对该线偏振光进行杂光的过滤处理，因此上述线偏振光在液晶显示面板11上还是显示一团白色，并不能真实的显示画面内容。
但是偏光眼镜12上设置有第二偏光板106，第二偏光板106用于将液晶显示面板11的出射光线转换为显示光线，由于第二偏光板106的偏光轴的方向与第一偏光板102的偏光轴的方向垂直，因此第二偏光板106可对液晶显示面板11出射的线偏振光进行过滤，从而留下显示真实画面内容的线偏振光。
因此液晶显示系统10前的用户并不能观看到该液晶显示系统的显示内容，用户只有通过佩戴偏光眼镜12才能观看到液晶显示系统10的真实画面内容，从而实现了液晶显示系统10前的特定用户的隐秘显示。
本优选实施例的液晶显示系统通过在偏光眼镜上设置第二偏光板，实现了对佩戴偏光眼镜的特定用户进行隐私显示。
请参照图2，图2为本发明的液晶显示系统的第二优选实施例的结构示意图。本优选实施例的液晶显示系统20包括背光模块（图中未示出）、液晶显示面板21以及偏光眼镜22。
该液晶显示面板21包括第一偏光板202、液晶层204、阵列基板203以及彩膜基板205；第一偏光板202用于将背光模块的出射光线201转换为线偏振光；液晶层204用于对第一偏光板202出射的线偏振光进行旋光操作；阵列基板203用于控制液晶层204中的液晶分子的偏转角度，以控制线偏振光的旋光角度；彩膜基板205用于将线偏振光转换为具有显示色彩的线偏振光。偏光眼镜22包括第二偏光板206，第二偏光板206用于将液晶显示面板21的出射光线转换为显示光线。
在液晶显示系统的第一优选实施例的基础上，本优选实施例的液晶显示系统20的偏光眼镜22还包括控制器207，该控制器207用于控制第二偏光板206的偏光轴的方向。当偏光眼镜22显示液晶显示面板21的显示画面时，控制器207控制第二偏光板206的偏光轴的方向与第一偏光板202的偏光轴的方向垂直，从而偏光眼镜22上可隐私的显示真实画面内容（如图1所示）；当偏光眼镜22不显示液晶显示面板21的显示画面时，控制器207控制第二偏光板206的偏光轴的方向与第一偏光板202的偏光轴方向平行，从而偏光眼镜22上也不能显示真实的画面内容（如图2所示）。
本优选实施例的液晶显示系统通过设置控制器可开启或关闭偏光眼镜，进一步提高了该液晶显示系统的隐私显示效果。
请参照图3和图4，图3为本发明的液晶显示系统的第三优选实施例的结构示意图之一；图4为本发明的液晶显示系统的第三优选实施例的结构示意图之二。本优选实施例的液晶显示系统30包括背光模块（图中未示出）、液晶显示面板31以及偏光眼镜32。
该液晶显示面板31包括第一偏光板302、液晶层304、阵列基板303以及彩膜基板305；第一偏光板302用于将背光模块的出射光线301转换为线偏振光；液晶层304用于对第一偏光板302出射的线偏振光进行旋光操作；阵列基板303用于控制液晶层304中的液晶分子的偏转角度，以控制线偏振光的旋光角度；彩膜基板305用于将线偏振光转换为具有显示色彩的线偏振光。偏光眼镜32包括第二偏光板306，第二偏光板306用于将液晶显示面板31的出射光线转换为显示光线。
在液晶显示系统的第一优选实施例的基础上，本优选实施例的液晶显示系统30的偏光眼镜32还包括控制器307以及第三偏光板308，该控制器307用于控制第三偏光板308的偏光轴的方向，当偏光眼镜32显示液晶显示面板31的显示画面时，第三偏光板308的偏光轴的方向与第二偏光板306的偏光轴的方向平行；当偏光眼镜32不显示液晶显示面板31的显示画面时，第三偏光板308的偏光轴的方向与第二偏光板306的偏光轴的方向垂直。
本优选实施例的液晶显示系统30使用时，当偏光眼镜32显示液晶显示面板31的显示画面时，控制器307控制第三偏光板308的偏光轴的方向与第二偏光板306的偏光轴的方向平行，这时第二偏光板306的偏光轴的方向与第一偏光板302的偏光轴的方向垂直，从而偏光眼镜32上可隐私的显示真实画面内容（如图4所示）。当偏光眼镜32不显示液晶显示面板31的显示画面时，控制器307控制第三偏光板308的偏光轴的方向与第二偏光板306的偏光轴的方向垂直，这时偏光眼镜32已经完全不透光，从而偏光眼镜32上也不能显示真实的画面内容（如图3所示）。
本优选实施例的液晶显示系统通过设置控制器和第三偏光板可开启或关闭偏光眼镜，进一步提高了该液晶显示系统的隐私显示效果。
本发明的液晶显示系统通过在偏光眼镜上设置第二偏光板，实现了对佩戴偏光眼镜的特定用户进行隐私显示；解决了现有的液晶显示系统不能实现对液晶显示装置前的特定用户进行隐私显示的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
