具体实施方式
为使本公开文本要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如上所述，现有技术中的支持2D/3D显示模式切换的显示装置，在处于某种显示模式时，需要持续地施加特定的电信号，以维持当前的显示状态，由此造成设备功耗较大，不符合绿色环保的技术发展趋势。
为克服现有技术的以上不足，本公开文本实施例提供了一种显示装置，如图1所示，该显示装置包括一显示面板2，还包括设置于所述显示面板2上的一光栅结构1。另外，在光栅结构1下还可以设置一背光模组3以提供背光源。本公开文本实施例中，设置在所述显示面板2和背光模组3之间的光栅结构1，可以支持2D/3D显示模式的切换功能，并且相比于现有技术的光栅结构，本公开文本实施例能够大大减少显示装置的功耗。
下面将对本公开文本实施例的光栅结构1进行详细说明。
本公开文本实施例提供的光栅结构，支持2D/3D显示模式切换功能，且只需要在显示模式切换的瞬间需要一定的能耗。在显示模式切换完成之后，当前的显示状态不需要持续施加电信号即可维持，进而不需要持续的能量，从而可以在很大程度上节约设备能耗。具体的，请参照图2至图4所示，本公开文本一实施例提供的光栅结构，包括相对设置的入光面11和出光面12，还包括位于所述出光面12和入光面11之间、呈连续排列的多个光栅单元13，每一个光栅单元13包括：
容纳腔131；
容纳于所述容纳腔131中、具有预定电极性、且不透光的电子油墨132；
设置在所述容纳腔131的腔体周围的控制模块(图中未示出)，用于控制所述电子油墨132在所述容纳腔131中所处的区域；
在所述控制模块施加电信号时，所述电子油墨132运动至所述容纳腔131中对应的区域；在所述控制模块撤销电信号后，所述电子油墨132则维持在 当前所在区域内。
可以看出，本公开文本实施例在需要切换显示模式时，所述控制模块施加电信号以产生电场，所述电子油墨132在电场作用下运动至所述容纳腔131中对应的区域，使光栅结构形成目标显示模式对应的结构；在所述控制模块撤销所施加的电信号时，所述电子油墨132维持在当前区域内，维持当前的显示模式。
本公开文本实施例中，所述电子油墨132可以采用聚合物形成，该电子油墨132整体呈正极性或负极性，且具有不透光的部分，例如整体均不透光，或者部分透光部分不透光。所述电子油墨132可以是规则/不规则形状。作为一个实施例，本公开文本中的电子油墨可以是整体呈现第一电极性或第二电极性的球体结构，包括不能透光且呈第一电极性的第一半球体，以及能够反光且呈第二电极性的第二半球体，其中，第一电极性和第二电极性极性相反。可见，第一半球体和第二半球体的电极性相反，且两者大小不等，从而使得电子油墨在整体上呈现具有较大电极性的半球体所具有的电极性。例如，电子油墨可以是半黑半白型的电子油墨，其由呈黑色的黑半球体和呈白色的白半球体组成，其中，黑、白半球体分别呈不同的电极性，而电子油墨作为一个整体呈现的电极性与黑半球体的电极性相同，或者与白半球体的电极性相同。
上述电子油墨132可以采用各种已有技术进行制造。为帮助理解，在本文最后将对电子油墨的制造进行简单说明，此处不再赘述。
本公开文本实施例中，在所述控制模块施加第一电信号时，油墨在电场作用下运动至所述容纳腔131中的第一区域时，所述容纳腔131中形成有从入光面11到出光面12的透光通道；以及，在控制模块施加第二电信号时，电子油墨在电场作用下运动至所述容纳腔131中的第二区域时，所述电子油墨形成一阻挡来自入光面11的光线从出光面12透出的阻挡层。当电信号撤销后，电子油墨将停留在当前区域内，保持当前形成的透光通道或者阻挡层。
本公开文本实施例中，可以通过施加对应的电信号，在电子油墨形成所述阻挡层时，所述电子油墨的第一半球体朝向所述出光面12，第二半球体朝向所述入光面11。这样，不但可以利用第一半球体的不透光功能，阻止入光 面11入射的光线透过电子油墨到达出光面12，同时，还可以利用第二半球体的反光功能，将入光面11入射的光线反射回入光面11。通常，入光面11侧由背光源来提供入射光，此时，第二半球体可以将光线反射回去，减少阻挡层需要阻挡的入射光，在改善阻挡层光线阻挡效果的同时，还可以大大提高背光源的光利用效率。具体的，电信号施加方式将在后文中进一步说明。
进一步的，请参考图4，本公开文本实施例提供了控制模块的一种具体实现结构，如图4所示，所述控制模块可以包括：
位于所述容纳腔131的侧壁的至少一个第一电极结构133(如图4中的腔体侧壁的阴影填充部分所示)；
位于所述容纳腔131的顶部和/或底部的第二电极结构134(如图4中的腔体顶部和底部的阴影填充部分所示)；和
通电控制单元(图4中未示出)，用于通过所述第一电极结构133和/或第二电极结构134产生作用于所述电子油墨132的电场，控制所述电子油墨132运动至所述容纳腔131中对应的区域。
本公开文本实施例中，在所述通电控制单元向所述第一电极结构133施加第一电信号时，所述电子油墨运动至所述容纳腔131中的第一区域时，所述容纳腔131中形成有从入光面11到出光面12的透光通道。
在所述通电控制单元向所述第二电极结构134施加第二电信号时，所述电子油墨运动至所述容纳腔131中的第二区域时，所述电子油墨形成一阻挡来自入光面11的光线从出光面12透出的阻挡层。
这里，所述第一区域贴近于容纳腔131的侧壁的区域，例如，与所述容纳腔131的侧壁之间距离小于第一预设值的区域，所述第二区域是贴近于所述容纳腔131的顶部或底部的区域，例如，与所述容纳腔131的顶部或底部之间距离小于第二预设值的区域。具体的，第一、第二预设值可以根据3D显示模式下的光栅指标要求进行设置。
本公开文本实施例中，根据所需要的显示模式，各个光栅单元13的控制模块通过施加适当的电信号，控制电子油墨132运动到对应的区域中，使得光栅结构形成该显示模式对应的结构。
作为本公开文本的一个实施例，在需要由2D显示切换至3D显示时，相 邻光栅单元13的控制模块分别控制相邻光栅单元13处于相反的光透过状态，即某个光栅单元13允许光透过时，则与该光栅单元13相邻的另一光栅单元13阻止光透过，从而形成3D光栅结构。
如图2所示，光栅单元13b的控制模块施加第一电信号时，其容纳腔131内的电子油墨运动至所述容纳腔131中的第一区域(分别贴近于腔体的侧壁)时，从而在所述容纳腔131中形成有从入光面11到出光面12的透光通道。而相邻的光栅单元13a的控制模块施加第二电信号时，其容纳腔131内的电子油墨运动至所述容纳腔131中的第二区域(贴近于出光面12)时，所述电子油墨形成一阻挡来自入光面11的光线从出光面12透出的阻挡层。相邻光栅单元13的控制模块均施加类似的电信号，使得光栅单元13形成3D模式对应的结构。
本公开文本实施例中，还可以在电子油墨132的表面覆盖一反光层，从而在形成所述阻挡层时，这样，背光源从入光面11入射的光线可以被更好地反射回去，以提高背光源的光利用效率。
在显示模式切换至3D模式后，可以撤销各个控制模块上施加的电信号，此时各个电子油墨132将维持在当前区域内，因此当前的3D显示模式得以维持，而不需要持续地施加电信号，从而可以大大减少显示模式维持产生的能耗，达到绿色环保的目的。
作为本公开文本的另一实施例，在需要由3D显示切换至2D显示时，各个光栅单元13的控制模块通过施加第一电信号，可以分别控制各个光栅单元13均允许光透过，如图3所示，原来的3D光栅结构消失。在显示模式切换完成之后，可以撤销各个控制模块上施加的电信号，此时各个电子油墨132将维持在当前区域内，因此当前的2D显示模式得以维持，而不需要持续地施加电信号，以减少显示模式维持所需能耗。
作为一实施方式，本公开文本实施例中所述电子油墨132为整体呈现第一电极性的球体结构，包括不能透光且呈第一电极性的第一半球体、以及能够反光且呈第二电极性的第二半球体，第一电极性和第二电极性极性相反。为利用第二半球体的反光特性，本公开文本实施例中，在施加第二电信号形成所述阻挡层时，可以在入光面11一侧的第二电极结构上施加呈第一电极性 的电信号，在出光面12一侧的第二电极结构上施加呈第二电极性的电信号。即，在入光面11一侧的电极上施加的电信号的极性与第二半球体极性相反，而出光面12一侧的电极上施加的电信号的极性与第一球体极性相反，这样，电子油墨132的第二半球体的球面将朝向入光面11一侧，第一半球体则朝向出光面12一侧，从而在形成阻挡层的同时，还可以进一步反射来自入光面11的背光源的光线，从而提高背光源的光利用效率。
本公开文本实施例中，在控制电子油墨132的第二半球体的球面将朝向入光面11一侧，第一半球体则朝向出光面12一侧时，可以采用单电极控制或双电极控制方式。其中，在单电极控制时，可以仅在入光面11一侧的第二电极结构上施加呈第一电极性的电信号，或者，仅在出光面12一侧的第二电极结构上施加呈第二电极性的电信号。在双电极控制时，在入光面11一侧的第二电极结构上施加呈第一电极性的电信号，同时在出光面12一侧的第二电极结构上施加呈第二电极性的电信号。
下面进一步结合附图来说明本公开文本实施例中可以采用电极结构的设置方式，以及，在需要进行3D/2D显示模式切换时，所施加的电信号/电场方向。
1)电子油墨132整体均不透光，第一电极结构133和第二电极结构134均为单电极，且施加在电极结构133、134上的电信号电极性与电子油墨132的极性相同。
图5中，电子油墨132整体均不透光，且整体呈正电性。此时，光栅单元中的第一电极结构133和第二电极结构134都是单电极结构，其中第二电极结构134为设置在腔体顶部的电极。在需要在容纳腔131内形成光线阻挡层时，可以在腔体顶部的第二电极结构134上施加正电压后，电子油墨132在电场E的作用下运动至腔体底部，形成阻碍入光面光线进入的阻挡层。在需要在容纳腔131内形成透光通道时，可以在第一电极结构133上施加正电压，此时电子油墨132运动至腔体的对端侧壁处，使得入光面的入射光线得以通过。
图6与图5类似，不同的是，第二电极结构134是设置在腔体底部的电极，因此在第二电极结构134上施加正电压后，此时电子油墨132运动至腔 体顶部，形成阻碍入光面光线进入的阻挡层。
2)电子油墨132整体均不透光，第一电极结构133和第二电极结构134均为单电极，且施加在电极结构133、134上的电信号电极性与电子油墨132的极性相反。
图7中，电子油墨132整体均不透光，且整体呈正电性。此时，光栅单元中的第一电极结构133和第二电极结构134都是单电极结构，其中第二电极结构134为设置在腔体顶部的电极。在需要在容纳腔131内形成光线阻挡层时，可以在腔体顶部的第二电极结构134上施加负电压后，电子油墨132在电场E的作用下运动至腔体顶部，形成阻碍入光面光线进入的阻挡层。在需要在容纳腔131内形成透光通道时，可以在第一电极结构133上施加负电压，此时电子油墨132运动至第一电极结构133侧的侧壁处，使得入光面的入射光线得以通过。
图8与图7类似，不同的是，第二电极结构134是设置在腔体底部的电极，因此在第二电极结构134上施加负电压后，此时电子油墨132运动至腔体底部，形成阻碍入光面光线进入的阻挡层。
3)电子油墨132整体均不透光，第一电极结构133和第二电极结构134均为双电极。
图9中，电子油墨132整体均不透光，且整体呈正电性。此时，光栅单元中的第一电极结构133和第二电极结构134都是双电极结构，分别包括两个相对设置的子电极，其中第二电极结构134包括位于在腔体底部和顶部的电极，第一电极结构133包括位于在相对设置的两个侧壁上的电极。在需要在容纳腔内形成光线阻挡层时，可以在腔体顶部的第二电极结构134上施加正电压，在腔体底部的第二电极结构134上施加负电压后，电子油墨132在电场E的作用下运动至腔体底部，形成阻碍入光面光线进入的阻挡层。在需要在容纳腔内形成透光通道时，可以在图9所示的左侧第一电极结构133上施加正电压，在右侧第一电极结构133上施加负电压，此时电子油墨132运动至右侧第一电极结构133附近的侧壁处，使得入光面的入射光线得以通过。
图10与图9类似，不同的是，施加在电极结构133、134上的电压极性相反，从而电子油墨132运动方向也是与图9相反，此处不再赘述。
4)电子油墨132部分反光、部分不透光，第一电极结构133和第二电极结构134均为单电极。
图11中，入光面在腔体底部一侧，出光面在腔体顶部一侧。电子油墨132的半个球体反光，且呈负电性，另半个球体不透光，且呈正电性，作为一个整体，电子油墨132整体呈正电性。具体的，电子油墨132可以采用半黑半白形式，其中黑色半球体不透光，而白色半球体能够反光。此时，光栅单元中的第一电极结构133和第二电极结构134都是单电极结构，其中第二电极结构134为设置在腔体顶部的电极。在需要在容纳腔131内形成光线阻挡层时，可以在腔体顶部的第二电极结构134上施加负电压后(即出光面一侧的电极上施加电极性与不透光半球体相反的电信号)，电子油墨132在电场E的作用下运动至腔体顶部，形成阻碍入光面光线进入的阻挡层，此时不透光半球体朝向出光面，而反光半球体朝向入光面，可以将入光面的光线反射回去，提高入光面背光源的光利用效率。在需要在容纳腔131内形成透光通道时，可以在第一电极结构133上施加负电压，此时电子油墨132运动至第一电极结构133侧的侧壁处，使得入光面的入射光线得以通过。
图12与图11类似，不同的是，第二电极结构134是设置在腔体底部的单电极，因此在第二电极结构134上施加正电压(即入光面一侧的电极上施加电极性与反光半球体相反的电信号)后，此时电子油墨132运动至腔体顶部，形成阻碍入光面光线进入的阻挡层，此时不透光半球体朝向出光面，而反光半球体朝向入光面，可以将入光面的光线反射回去，提高入光面背光源的光利用效率。在第一电极结构133上施加正电压，此时电子油墨132运动至对端侧壁处，使得入光面的入射光线得以通过。
5)电子油墨132部分透光、部分不透光，第一电极结构133和第二电极结构134均为双电极。
图13中，入光面一侧的电极上施加电极性与反光半球体相反的电信号。电子油墨132的半个球体反光，且呈负电性，另半个球体不透光，且呈正电性，作为一个整体，电子油墨132整体呈正电性。此时，光栅单元中的第一电极结构133和第二电极结构134都是双电极结构，分别包括两个相对设置的子电极，其中第二电极结构134包括位于在腔体底部和顶部的电极，第一 电极结构133包括位于在相对设置的两个侧壁上的电极。在需要在容纳腔内形成光线阻挡层时，可以在腔体顶部的第二电极结构134上施加负电压，在腔体底部的第二电极结构134上施加正电压后(即出光面一侧的电极上施加电极性与不透光半球体相反的电信号，入光面一侧的电极上施加电极性与反光半球体相反的电信号)，电子油墨132在电场E的作用下运动至腔体顶部，形成阻碍入光面光线进入的阻挡层。在需要在容纳腔内形成透光通道时，可以在图13所示的左侧第一电极结构133上施加负电压，在右侧第一电极结构133上施加正电压，此时电子油墨132运动至左侧第一电极结构133附近的侧壁处，使得入光面的入射光线得以通过。
以上图11-13的举例中，电子油墨132的整体电极性与不透光半球体的极性相同。可以理解，本公开文本实施例中，电子油墨132的整体电极性可以与反光半球体的极性相同，在这种情况下，在实现阻挡层且希望反光半球体朝向入光面一侧时，施加的电信号与以上举例相同。所不同的是，由于电子油墨132整体电极性与以上举例相反，因此，电子油墨132运动至的区域与图11-13中相反，例如，在图11的左侧图示中电子油墨132运动至腔体顶部区域，而在电子油墨132的整体电极性与可以与反光半球体的极性相同的情况下，则电子油墨132将运动至腔体底部区域，为节约篇幅，不再赘述。
以上举例仅为本公开文本可以采用的部分电极结构及电场/电压施加方式。在以上结构的启示下，本领域技术人员可以了解，还可以在第一电极结构采用单电极，第二电极结构采用双电极，或者在第二电极结构采用单电极，第一电极结构采用双电极。更进一步的，本公开文本实施例还可以在不同的光栅单元中采用不同的电极结构，为节约篇幅，不再赘述。
最后，对本公开文本实施例中所述的电子油墨进行简单说明。本公开文本实施例中，电子油墨可以是由聚合物制造而成。可选的，该电子油墨可以是一种带电的电子油墨球体，且为半黑半白型，即包括一个黑色半球体和一个白色半球体。其中黑色部分主要起到吸光/阻挡光线通过的作用，白色部分主要起到反光作用。带电球黑色部分带有正电荷，白色部分带有负电荷，整体可以呈现正电性。该带电小球可以采用现有的微通道方法制作。
微通道制造方法是使用着色连续相和球状粒子化相彼此存在呈O/W(水 包油)或W/O(油包水)型的关系，从移送着色连续相的第一微通道，向在第二微通道中流动的流动介质的球状粒子化相内，依次喷出2色的着色连续相，由此制造出2色相球状聚合物粒子、且在电荷方面具有正负极性的双极性球状粒子球。具体的：
在含有聚合性树脂成分的油性或水性的流动性介质中，利用以互不相同的正负带电的聚合性单体形成在该介质中含有不溶性的着色染颜料的分相为2色的着色连续相中的聚合性树脂成分，并移送到第一微通道；
接下来，将该着色连续相，连续或间歇性地依次喷出到在第二微通道内流动的水性或油性的球状粒子化相中；
接下来，喷出到球状粒子化相中的喷出物，一边在微通道内的一系列的喷出/分散/移送中被球状粒子化，一边在球状粒子化相中被依次球状物化，因此，使该球状化粒子中的聚合性树脂成分在U V照射下以及/或加热下聚合硬化，从而对小球进行适当调制。
上述着色连续相，是被分相为2色相的连续色相，例如，能够列举出从黑色/白色作为形成这种色相的着色剂，能够在后述的含有聚合性树脂成分的流动性分散介质中具有不溶性或均匀分散即可，不作特别的限定，能够适宜选择而使用。
作为上述着色剂，黑色部分主要选择炭黑，白色部分为了达到更好的反光效果，主要采用化学镀银方法实现。
本方式中，能够相对于作为着色连续相中的聚合硬化成分的全聚合性树脂成分每100重量份，以0.1重量份～80重量份，优选为2重量份～10重量份的范围适当良好地进行添加。
作为上述球中所使用的聚合性树脂成分(或聚合性单体)，根据扭转球中所使用的聚合性单体的官能基或置换基的种类，能够列举出处于上述扭转球的带电性分别显示出(-)带电性和(+)带电性倾向的单体种。因此，在将至少2种以上的多种单体作为本方式中的聚合性树脂成分而使用的情况下，周知其表现出(+)以及(-)带电性倾向，优选为，将处于同种带电性倾向的单体彼此多个组合而适当适宜地使用。
以上，使用着色连续相和球状粒子化相彼此存在O/W型或W/O型的关 系，从移送着色连续相的第一微通道，向在第二微通道中流动的流动介质的球状粒子化相内，依次喷出2色的着色连续相，由此制造出2色相球状聚合物粒子、且在电荷方面具有正负极性的双极性球状粒子。并且，黑色与白色带电部分所带电荷不对称，从而整体上保持一种带电型，而不是电中性。
更多的，关于微通道制造方法，还可以参考中国专利申请号200380104921.2的专利申请文件，为节约篇幅，此处不再赘述。
以上所述是本公开文本的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开文本所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开文本的保护范围。
