Description

同时由于液晶的光学特性，液晶显示装置需要设置上偏光板16和下偏光板12才能正常工作，这样导致显示画面的出射光为偏振光，并非外界的自然光。

第二蓝色平面光通过下偏光板26转换为第二蓝色偏振光，该第二蓝色偏振光通过阵列基板23、液晶层24、上基板25以及上偏光板26后，通过量子激发彩膜层27中的量子点材料转换为绿色平面光。
第三蓝色平面光通过下偏光板26转换为第三蓝色偏振光，该第三蓝色偏振光通过阵列基板23、液晶层24、上基板25以及上偏光板26后，通过量子激发彩膜层27中的量子点材料转换为红色平面光。
该液晶显示装置20的每帧画面包括第一子画面帧、第二子画面帧以及第三子画面帧，蓝色背光源21在显示第一子画面帧时发出第一蓝色平面光，在显示第二子画面帧时发出第二蓝色平面光，在显示第三子画面帧时发出第三蓝色平面光。这样第一子画面帧对应的蓝色平面光、第二子画面帧对应的绿色平面光以及第三子画面帧对应的红色平面光合成当前帧的彩色图案。
下面通过图4和图5说明本优选实施例的液晶显示装置的工作原理。图4为本发明的液晶显示装置的优选实施例的像素结构示意图；图5为本发明的液晶显示装置的画面帧的驱动示意图。该液晶显示装置的每帧画面由第一子画面帧、第二子画面帧以及第三子画面帧叠加而成。
当显示第一子画面帧时，蓝色背光源21发出第一蓝色平面光，第一蓝色平面光通过下偏光板22转换为第一蓝色偏振光，该第一蓝色偏振光通过液晶层24中的液晶分子进行调制，随后通过上偏光板25将调制后的第一蓝色偏振光出射至量子激发彩膜层27，量子激发彩膜层27中的量子点材料将具有第一波长的第一蓝色平面光转换为蓝色平面光后射出。
当显示第二子画面帧时，蓝色背光源21发出第二蓝色平面光，第二蓝色平面光通过下偏光板22转换为第二蓝色偏振光，该第二蓝色偏振光通过液晶层24中的液晶分子进行调制，随后通过上偏光板25将调制后的第二蓝色偏振光出射至量子激发彩膜层27，量子激发彩膜层27中的量子点材料将具有第二波长的第二蓝色平面光转换为绿色平面光后射出。
当显示第三子画面帧时，蓝色背光源21发出第三蓝色平面光，第三蓝色平面光通过下偏光板22转换为第三蓝色偏振光，该第三蓝色偏振光通过液晶层24中的液晶分子进行调制，随后通过上偏光板25将调制后的第三蓝色偏振光出射至量子激发彩膜层27，量子激发彩膜层27中的量子点材料将具有第三波长的第三蓝色平面光转换为红色平面光后射出。
最后第一子画面帧对应的蓝色平面光、第二子画面帧对应的绿色平面光以及第三子画面帧对应的红色平面光合成当前画面帧的彩色图案。
随后显示下一画面帧的第一子画面帧、第二子画面帧以及第三子画面帧，以形成后续画面帧的彩色图案。
同时由于蓝色平面光、绿色平面光以及红色平面光分别由不同波长的蓝色平面光激发，因此不需要在阵列基板23上设置不同颜色的像素单元，如图4所示，阵列基板23设置有可显示蓝色平面光、绿色平面光以及红色平面光的像素单元R/G/B，上基板25上也不需要设置彩膜色阻，只需要相应的增加液晶显示装置20的刷新频率即可实现液晶显示装置20的彩色图案的显示。
本优选实施例的液晶显示装置20直接使用发光效率较高的蓝色背光源21进行画面显示，因此提高了液晶显示装置20的发光效率。同时本优选实施例的液晶显示装置20通过量子激发彩膜层27可发出包含彩色图案的平面光，增大了液晶显示装置20的显示视角。
本发明的液晶显示装置通过具有三种波长的蓝色平面光的蓝色背光源的设置可发出彩色自然光，且提高了液晶显示装置的发光效率以及增大了液晶显示装置的显示视角；解决了现有的液晶显示装置不可发出彩色自然光、发光效率较低且显示视角较窄的技术问题。
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。
