在制备过程中，通常先制备数个排布于第一大板玻璃上的阵列基板以及数个排布于第二大板玻璃上的彩膜基板，然后，将两个大板玻璃上的阵列基板和彩膜基板对盒以制成液晶显示面板。
通常在对盒之前，需要分别在阵列基板和彩膜基板上涂布上配向膜，再利用摩擦配向（rubbing）工艺处理配向膜，使配向膜具有让液晶分子以某一个预倾角沿着统一方向排列的能力。但是，上述仅适用于配向方向统一的情况，当大板玻璃上排布的数个阵列基板对应的液晶分子需要不同的配向方向时，摩擦配向的工艺难度增加，将不再适用。

本申请实施例提供一种液晶显示装置，该液晶显示装置可以为各种电子设备或者该液晶显示装置可以应用于各种电子设备中。
其中，电子设备可以为智能手机、平板电脑、电子阅读器、车载电脑、导航仪、数码相机、智能电视机以及智能可穿戴设备等多种不同类型的电子设备。本申请实施例对此不进行任何限制。
在现有技术中，液晶显示装置大部分为背光型液晶显示装置，图1示出了一种背光型液晶显示装置的结构示意图。如图1所示，该液晶显示装置的主要结构包括框架1、盖板2、液晶显示面板3、背光模组4、电路板5以及包括摄像头等的其他电子配件。液晶显示面板3包括阵列基板31、对置基板、设置于阵列基板31和对置基板之间的液晶层33，阵列基板31和对置基板通过封框胶对合在一起，从而将液晶层33限定在封框胶围成的区域内。其中，通常彩色滤光层设置于对置基板上，并将此对置基板称为彩膜基板32。
如图1所示，以框架1的纵截面呈U型为例，液晶显示面板3、背光模组4、电路板5以及包括摄像头等的其他电子配件设置于框架1内，背光模组4位于液晶显示面板3的下方，电路板5位于背光模组4和框架1之间，盖板2位于液晶显示面板3远离背光模组4的一侧。盖板2，例如可以是透明玻璃。
基于图1所示的液晶显示装置，在图1中，光路的传播顺序为：背光模组4射出，依次透过阵列基板31、液晶层33、彩膜基板32、射出盖板2。
上述对现有的液晶显示装置的结构进行了详细描述，然而，制备这种结构的液晶显示装置中的液晶显示面板3时，需要先将彩膜基板32和阵列基板31分别制备好，然后再涂布封框胶对盒起来，形成液晶盒30。
图2示出了范例技术中提供的第一大板玻璃和第二大板玻璃的结构示意图。
如图2所示，在液晶显示面板3的制造过程中，首先，先在整面的第一大板玻璃51上制备出数个阵列基板31（图2中以6个为例），在另一整面的第二大板玻璃52上制备出数个彩膜基板32（图2中以6个为例）。然后，在其中一个大板玻璃的数个基板（即阵列基板31或彩膜基板32）中的每个基板的显示区10***的周边区20中，利用涂布设备涂布一圈封框胶；在封框胶围成的区域内灌注液晶；再将第一大板玻璃51和第二大板玻璃52对合，从而利用封框胶将对应的一组阵列基板31和彩膜基板32粘结在一起形成一个液晶盒30；再沿第一大板玻璃51和第二大板玻璃52上预设的切割线位置，切割出多个液晶显示面板3。
在此基础上，在阵列基板31和彩膜基板32涂布封框胶之前，通常还需要分别在阵列基板31和彩膜基板32上涂布一层配向膜40。为了工艺简单，一般是在排布数个阵列基板31的第一大板玻璃51和排布数个彩膜基板32的第二大板玻璃52上涂布整层的配向膜40，然后，利用摩擦配向（利用滚筒外侧的布料，根据力学原理产生摩擦进行配向）工艺处理配向膜40，使配向膜40具有让液晶分子以某一个预倾角沿着统一方向排列的能力。这样，在阵列基板31和彩膜基板32对盒之后，配向膜40与液晶层33中的液晶接触，就能够使液晶产生一定方向的预倾角，从而给液晶分子提供一个角度。其中，该预倾角的大小对液晶显示面板3的驱动电压、对比度、响应时间、视角等具有重要的影响。
但是，上述方法仅适用于数个阵列基板31或彩膜基板32对应的液晶配向方向统一的情况，当数个阵列基板31或彩膜基板所对应的液晶分子需要不同的配向方向时，在制备过程中，将需要进行多次不同方向的摩擦配向，且在摩擦配向时有可能对周边区域产生干扰。由此，当需要不同配向方向时，摩擦配向的工艺难度大大增加，摩擦配向将不再适用。
示例性的，图3示出了一种第一大板玻璃51上排布数个不同配向方向的阵列基板31的排列示意图。如图3所示，以如图3中所示的x方向为行方向，y方向为列方向为例，第一行和第三行的多个阵列基板31中的液晶需要沿行方向的配向，第二行和第四行的多个阵列基板31中的液晶需要沿列方向的配向。例如，若先对第一行的阵列基板31对应区域中的配向膜40进行摩擦配向，再对第二行的阵列基板31对应区域中的配向膜40进行摩擦配向，则有可能影响到第一行的阵列基板31对应区域中已经配向过的配向膜40。同理，对第二大板玻璃52上排布的数个彩膜基板32进行不同配向方向的摩擦配向时，也会出现互相影响。
为此，有人提出在进行设计时，将相同配向方向的阵列基板31或彩膜基板32排布在一起，这样就可以将第一大板玻璃51和第二大板玻璃52分区进行摩擦配向。
示例性的，图4示出了另一种第一大板玻璃51上排布数个不同配向方向的阵列基板31的排列示意图。如图4所示，将图3中第二行的阵列基板31和第三行的阵列基板31的位置进行交换，由此，图4中的第一行和第二行阵列基板31对应配向方向均为水平方向，可以组成一个配向区，第三行和第四行阵列基板31对应配向方向均为垂直方向，可以组成另一个配向区。这样，可以对第一行和第二行阵列基板31对应的配向区中的配向膜40同时进行水平方向的配向，然后，再对第三行和第四行阵列基板31对应的配向区中的配向膜40同时进行垂直方向的配向。
虽然上述通过改变阵列基板31的排列方式可以降低一点摩擦配向难度，但是，当出现两种以上配向方向时，排布情况更加复杂，并不一定能简化排列方式，所以摩擦配向还是无法适用。
除此之外，在现有技术中，还有一种光配向（photo alignment）工艺。具体为：利用线偏振光照射到配向膜40上，在配向膜40表面形成一定倾斜角度的配向微结构，该配向微结构可以诱导液晶分子实现以某一预倾角沿着同一方向排列，也就是说，利用线偏振光照射配向膜40，可以使得照射后的配向膜40具有特定配向方向的配向能力，从而后续可以对液晶分子可以进行对应方向的配向。
但是，现有技术中，照射到第一大板玻璃51的每个阵列基板31上或照射到第二大板玻璃52的每个彩膜基板32上的线偏振光的偏振方向通常都是相同的，所以在数个阵列基板31或彩膜基板32所对应的液晶分子需要不同的配向方向时，现有的光配向工艺还是无法适用。
有鉴于此，本申请实施例提供一种光配向装置，该光配向装置通过在线偏振光光源和承载台之间设置控制组件，使得在承载台靠近控制组件的一侧放置待配向大板玻璃之后，控制组件能调整线偏振光光源发射的第一偏振光的偏振方向，从而向待配向大板玻璃包括的多个配向区提供第二偏振光。由于至少两个配向区对应的第二偏振光的偏振方向不同，所以可以生成对应不同配向方向的配向区，由此，可以利用控制组件实现同时进行多种方向的配向的目的。
下面结合图5~图10对本申请实施例提供的光配向装置的结构进行详细说明。图5是本申请实施例提供的一种光配向装置的结构示意图；图6是图5中的光配向装置沿AA'方向的截面示意图。图7是图6中区域P1的局部放大图。
如图5和图6所示，该光配向装置100，包括：承载台110、位于承载台110一侧的线偏振光光源130、及位于承载台110与线偏振光光源130之间的控制组件120。承载台110靠近控制组件120的一侧用于放置包括多个配向区210的待配向大板玻璃200。
线偏振光光源130，用于向控制组件120提供第一偏振光。
控制组件120，用于调整第一偏振光的偏振方向，并向待配向大板玻璃200包括的多个配向区210提供第二偏振光。
其中，至少两个配向区210分别对应的第二偏振光的偏振方向不同。
应理解，如图5和图6所示，该光配向装置100从上到下依次排布着线偏振光光源130、控制组件120和承载台110。
其中，为了能使得线偏振光光源130照射到所有控制组件120上，线偏振光光源130和控制组件120之间具有第一预设距离，该第一预设距离可以根据需要进行设置，本申请实施例对此不进行任何限制。
为了将待配向大板玻璃200放置在承载台110靠近控制组件120的一侧，因此，承载台110和控制组件120之间具有第二预设距离，该第二预设距离应该大于待配向大板玻璃200的高度。该第二预设距离可以根据需要进行设置，本申请实施例对此不进行任何限制。
由于一些配向区210可能设置在待配向大板玻璃200的边界处，为了让控制组件120能向待配向大板玻璃200的所有配向区210提供第二偏振光，因此，可以设置控制组件120平行于承载台110的边长大于或者等于待配向大板玻璃200平行于承载台110的边长。换句话说，可以设置控制组件120与承载台110、待配向大板玻璃200均平行，且控制组件120沿任一方向的边长大于或等于同一方向上待配向大板玻璃的边长。例如，控制组件120平行于承载台110且平行于第一方向x的边长，大于或等于待配向大板玻璃200平行于承载台110的同一方向上的边长。该控制组件120平行于承载台110的边长长度可以根据需要进行设置，本申请实施例对此不进行任何限制。
此外，光配向装置100还可以包括用于悬挂线偏振光光源130的支架，利用该支架将线偏振光光源130悬挂于控制组件120平行于承载台110的平面的中心。也即，线偏振光光源130在控制组件120上的投影位于控制组件120的中心。承载台110还可以设置成可移动的承载台110，便于放置待配向大板玻璃200和取出配向后的待配向大板玻璃200。
应理解，待配向大板玻璃200即为图2中所示的第一大板玻璃51或第二大板玻璃52，由于第一大板玻璃51上排布有多个阵列基板31，当多个阵列基板31对应的液晶分子需要不同的配向方向，或者，第二大板玻璃52上排布有多个彩膜基板32，当多个彩膜基板32对应的液晶分子需要不同的配向方向时，控制组件120可以根据需要调整入射的第一偏振光的偏振方向，生成不同偏振方向的第二偏振光对待配向大板玻璃200进行配向。
其中，针对每个配向区210，对应的第二偏振光可以与第一偏振光的偏振方向相同，也可以与第一偏振光的偏振方向不同。而多个配向区210对应的第二偏振光之间，至少有两个配向区210分别对应的第二偏振光的偏振方向应不同，从而可以生成对应不同配向方向的配向区210。
应理解，待配向大板玻璃上200的一个配向区210的尺寸可以大于、等于或者小于一个阵列基板31的尺寸或彩膜基板32的尺寸。
当第一大板玻璃51上的数个阵列基板31，或者第二大板玻璃52上的数个彩膜基板32排布的较为紧密时，为了简化配向设计，可以忽略阵列基板31之间的间隙，或者彩膜基板32之间的间隙，可认为待配向大板玻璃200上具有阵列排布的数个配向区。
本申请实施例提供了一种光配向装置，该光配向装置通过在线偏振光光源和承载台之间设置控制组件，使得在承载台靠近控制组件的一侧放置待配向大板玻璃之后，控制组件能调整线偏振光光源发射的第一偏振光的偏振方向，从而向待配向大板玻璃包括的多个配向区提供第二偏振光。由于至少两个配向区对应的第二偏振光的偏振方向不同，所以可以生成对应不同配向方向的配向区，由此，可以利用控制组件实现同时进行多种方向的配向的目的。
此外，相对于现有技术，本申请实施例提供的光配向装置用于配向时，工艺简单、时间短、精度高、工作效率也高。
可选地，作为一种可能的实现方式，待配向大板玻璃200靠近控制组件120一侧涂覆有配向膜40。第二偏振光用于对待配向大板玻璃200上位于配向区210内的配向膜40进行配向。
由于至少两个配向区对应的第二偏振光的偏振方向不同，所以在不同配向区位置处，可以生成对应不同配向方向的配向膜40，不同配向方向的配向膜40就可以对液晶分子进行不同方向的配向，由此，通过利用控制组件即可实现同时进行多种方向的配向的目的。
可选地，作为一种可能的实现方式，在配向膜40靠近控制组件120的一侧涂覆有感光剂。该感光剂用于与第二偏振光发生反应以完成配向膜40的配向。
可选地，作为一种可能实现的方式，待配向大板玻璃200上排布有多个阵列基板31，每个阵列基板31包括至少一个配向区210；或者，待配向大板玻璃200上排布有多个彩膜基板32，每个彩膜基板32包括至少一个配向区210。
如图5~图7所示，示例性一，待配向大板玻璃200为第一大板玻璃51，该待配向大板玻璃200上排布有6个阵列基板31，每个阵列基板31作为一个配向区210，其余区域不作配向，相应的，控制组件120可以调整第一偏振光的偏振方向，并向待配向大板玻璃200包括的6个配向区210提供第二偏振光。其中，至少两个配向区210，也就是说，至少两个阵列基板31所在区域对应的第二偏振光的偏振方向不同。
同理，待配向大板玻璃200还可以为第二大板玻璃52，该待配向大板玻璃200上排布有6个彩膜基板32，每个彩膜基板32作为一个配向区210，其余区域不作配向，相应的，控制组件120可以调整第一偏振光的偏振方向，并向待配向大板玻璃200包括的6个配向区210提供第二偏振光。其中，至少两个配向区210，也就是说，至少两个彩膜基板32所在区域对应的第二偏振光的偏振方向不同。
图8是本申请实施例提供的一种光配向装置的结构示意图；图9是图8中的光配向装置沿BB'方向的截面示意图；图10是图9中区域P2的局部放大图。
如图8~图10所示，示例性二，待配向大板玻璃200为第一大板玻璃51，该待配向大板玻璃200上排布有6个阵列基板31，每个阵列基板31包括阵列排布的6个配向区210，其余区域不作配向，相应的，控制组件120可以调整第一偏振光的偏振方向，并向待配向大板玻璃200包括的36个配向区210提供第二偏振光。其中，至少两个配向区210，也就是说，至少两个阵列基板31分别包括的一个配向区210，或者，一个阵列基板31包括的至少两个配向区210，对应的第二偏振光的偏振方向不同。
同理，待配向大板玻璃200还可以为第二大板玻璃52，该待配向大板玻璃200上排布有6个彩膜基板32，每个彩膜基板32包括阵列排布的6个配向区210，其余区域不作配向，相应的，控制组件120可以调整第一偏振光的偏振方向，并向待配向大板玻璃200包括的36个配向区210提供第二偏振光。其中，至少两个配向区210，也就是说，至少两个阵列基板31分别包括的一个配向区210，或者，一个阵列基板31包括的至少两个配向区210，对应的第二偏振光的偏振方向不同。
可选地，作为一种可能实现的方式，控制组件120包括多个控制模块121，控制模块121与待配向大板玻璃200上的配向区210一一对应。
如图5~图7所示，示例性一，当待配向大板玻璃200包括6个配向区210时，相应的，控制组件120可以包括6个控制模块121，每个控制模块121对应一个配向区210，其中，每个控制模块121设置于对应配向区210的正上方。其中，控制模块121平行于承载台110的边长大于或等于配向区210平行于承载台110的边长。
如图8~图10所示，示例性二，当待配向大板玻璃200包括36个配向区210时，相应的，控制组件120可以包括36个控制模块121，每个控制模块121对应一个配向区210，其中，每个控制模块121设置于对应配向区210的正上方。
应理解，配向区210的个数、形状、尺寸和位置均可以根据需要进行设置，相应的，控制模块121的个数、形状、尺寸和位置均随之变化，本申请实施例对此不进行任何限制。
控制模块121用于调整对应配向区210内的第一偏振光的偏振方向，形成第二偏振光。也就是说，每个控制模块121调整一个配向区210的配向方向。由此，通过不同的控制模块121调整相应的配向区210的第一偏振光的偏振方向，即可生成不同偏振方向的第二偏振光。
应理解，由于每个控制模块121都可以精确控制照射到待配向大板玻璃200上的一个配向区210的第一偏振光的偏振方向，从而可以通过调整多个控制模块121以达成待配向大板玻璃200上排布的数个阵列基板31或彩膜基板32对应的区域配置不同的液晶配向方向的需求。
基于此，可以通过减小控制模块121的尺寸，增加控制模块121的数量来提高控制精度，由此，能否满足多种基板各种复杂形势混排的配向需求。
还应理解，由于每个控制模块121调整一个配向区210的配向方向，所以，控制组件120包括的所有控制模块121可以同时调整所有配向区210的配向方向，相对于现有技术，不会增加额外的工艺时间。
可选地，作为一种可能实现的方式，如图7和图10所示，控制模块121包括：相对设置的第一基板1210和第二基板1220，以及位于第一基板1210和第二基板1220之间的配向液晶层1230，第一基板1210平行于承载台110。
应理解，由于第一基板1210和第二基板1220相对设置，所以第一基板1210平行于承载台110时，第二基板1220也平行于承载台110。并且，第一基板1210和第二基板1220均平行于待配向大板玻璃200以及待配向大板玻璃200上涂覆的配向膜40。
其中，控制模块121中的第一基板1210和第二基板1220的位置可以互换，即，第一基板1210可以设置于靠近承载台110的一侧，第二基板1220设置于靠近线偏振光光源130的一侧，或者，第一基板1210可以设置于靠近线偏振光光源130的一侧，第二基板1220设置于靠近承载台110的一侧。
在第一基板1210靠近配向液晶层1230的一侧，或者，在第二基板1210靠近配向液晶层1230的一侧设置有配向电极层1240，配向电极层1240用于向配向液晶层1230提供电压，电压用于控制配向液晶层1230中的液晶进行旋转，旋转的液晶用于调整第一偏振光的偏振方向。
应理解，在第一基板1210靠近配向液晶层1230的一侧设置有配向电极层1240，则从上到下或者从下到上，在控制模块121中的排列顺序为：第一基板1210、配向电极层1240、配向液晶层1230和第二基板1220。
在第二基板1220靠近配向液晶层1230的一侧设置有配向电极层1240，则从上到下或者从下到上，在控制模块121中的排列顺序为：第一基板1210、配向液晶层1230、配向电极层1240和第二基板1220。
可选地，作为一种可能的实现方式，配向电极层1240包括：间隔设置的第一电极1241和第二电极1242；第一电极1241和第二电极1242均平行承载台110。
第一电极1241用于向配向液晶层1230提供第一电压，第二电极1242用于向配向液晶层1230提供第二电压。
应理解，第一电极1241提供的第一电压和第二电极1242提供的第二电压的电压差可以改变配向液晶层中液晶的旋转程度，从而改变第一偏振的偏振方向。
示例性的，图11是图8~图10中待配向大板玻璃上数个不同配向方向的配向区的排列示意图。待配向大板玻璃200设置有两行三列阵列基板31，每个阵列基板31所在区域对应两行三列配向区210。
如图11所示，假设第一偏振光的偏振方向是沿x方向的，配向液晶层1240中的液晶的长轴沿x方向延伸。基于此，若设置于第一行第一列、第二行第二列阵列基板31对应的配向区210位置处的第一电极1241和第二电极1242上均未施加电压，则相应的液晶不会发生旋转，此时，出射的第二偏振光的偏振方向与第一偏振光的偏振方向相同，为x方向。若设置于第一行第二列、第一行第三列、第二行第一列、第二行第三列阵列基板31对应的配向区210位置处的第一电极1241和第二电极1242上施加有电压，则相应的液晶发生旋转，假设发生了90度旋转，此时，出射的第二偏振光的偏振方向与第一偏振光的偏振方向相互垂直，为y方向。
应理解，第一电极1241和第二电极1242还可以分层设置，例如，第一电极1241类似于阵列基板31中的公共电极，可以整层铺设，而第二电极1242设置于第一电极1241靠近液晶层的一侧，类似于阵列基板31中的像素电极，间隔设置。
应理解，配向电极层还可以包括其他与第一电极1241、第二电极1242连接的引线，用于将外界的电压传输至每个配向区位置处对应的第一电极1241、第二电极1242上。
可选地，作为一种可能的实现方式，线偏振光光源130包括：依次层叠设置的紫外光光源131、滤光片132和偏光片133。偏光片132位于紫外光光源131靠近控制组件120的一侧。
也就是说，如图5和图8所示，在线偏振光光源130中，从上到下，依次排列着紫外光光源131、滤光片132和偏光片133。
滤光片132用于对紫外光光源131提供的紫外光中预设波长的紫外光进行过滤，偏光片用于将过滤后的紫外光转化为第一偏振光。
滤光片132过滤掉一些不需要的光线，留下指定波长的光线以配合实际配向需求。过滤掉的紫外光的预设波长可以根据需要进行设置，本申请实施例对此不进行任何限制。例如，滤光片132可以过滤掉波长为240~370nm以外的紫外光。
在线偏振光光源130中，还可以设置灯罩，导光板等其他器件，用于充分利用第一偏振光。
上述对本申请实施例提供的光配向装置100的结构进行了说明，下面基于光配向装置，对光配向装置对应的光配向方法进行说明。图12为本申请实施例提供的光配向方法的流程示意图。
如图12所示，该光配向方法1200包括以下S110~S130。
S110、在承载台靠近控制组件的一侧放置包括多个配向区的待配向大板玻璃。
若承载台较大，可以同时在承载台上同时放置多片待配向大板玻璃，同时进行配向，以提高工作效率。
S120、线偏振光光源向控制组件提供第一偏振光。
S130、控制组件调整第一偏振光的偏振方向后，向待配向大板玻璃包括的多个配向区提供第二偏振光。
其中，至少两个配向区对应的第二偏振光的偏振方向不同。
当控制组件包括多个控制模块时，由于控制模块与待配向大板玻璃上的配向区一一对应，因此，可以调整每个控制模块以改变配向区对应位置处第一偏振光的偏振方向，形成不同偏振方向的第二偏振光。
本申请实施例提供一种光配向方法，通过在线偏振光光源和承载台之间设置控制组件，使得在承载台靠近控制组件的一侧放置待配向大板玻璃之后，控制组件能调整线偏振光光源发射的第一偏振光的偏振方向，从而向待配向大板玻璃包括的多个配向区提供不同偏振方向的第二偏振光。由于至少两个配向区对应的第二偏振光的偏振方向不同，所以可以生成对应不同配向方向的配向区，由此，可以利用控制组件实现同时进行多种方向的配向的目的。
此外，相对于现有技术，本申请实施例提供的光配向装置用于配向时，工艺简单、时间短、精度高、工作效率也高。
可选地，作为一种可能的实现方法，待配向大板玻璃靠近控制组件一侧涂覆有配向膜。第二偏振光对待配向大板玻璃上位于配向区内的配向膜进行配向。
由于至少两个配向区对应的第二偏振光的偏振方向不同，所以对应于不同的配向区位置处，可以生成对应不同配向方向的配向膜，由此，可以利用控制组件实现同时进行多种方向的配向的目的。
本申请实施例还提供一种计算机可读存储介质，所述计算机可读存储介质中存储有计算机程序或指令，当计算机读取并执行所述计算机程序或指令时，使得计算机执行所述的光配向方法1200。
本申请实施例提供的计算机可读存储介质的有益效果与上述光配向方法1200对应的有益效果相同，在此不再赘述。
以上所述实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围，均应包含在本申请的保护范围之内。
