 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本申请的描述中，需要理解的是，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多条”的含义是两条或两条以上，除非另有明确具体的限定。
请参阅图1、图2，图1为本申请实施例提供的背光组件的结构示意图；图2为本申请实施例提供的背光组件的分解结构示意图。如图1、图2所示，本申请实施例的背光组件10包括：一承载部件101、一侧入式背光模组102以及一液晶盒103。侧入式背光模组102以及液晶盒103均设置在承载部件101内，液晶盒103设置在侧入式背光模组102上。
其中，该侧入式背光模组102具有多个沿第一方向设置的发光单元1023，每一发光单元1023的发光状态均可单独控制。该液晶盒103具有多个沿第二方向设置的像素单元1034，每一像素单元1034均具有两种状态，第一种状态为透明态，第二种状态为暗雾态，每一像素单元1034的状态均可单独控制。多个发光单元1023与多个像素单元1034交叉设置。需要说明的是，本申请实施例中的第一方向和第二方向均不做限制，仅仅只需保证第一方向与第二方向为不同方向即可。
其中，在一种实施方式中，该液晶盒103可以为高分子分散型液晶盒。在另一种实施方式中，该液晶盒103可以为网状聚合物液晶盒。
本申请实施例的背光组件10将侧入式背光模组102与液晶盒103结合在一起使用，通过单独控制每一发光单元1023的发光状态以及单独控制每一像素单元1034的状态，实现对背光组件10的二维分区控制，从而可以提高显示对比度，进而提高显示质量。在一种实施例方式中，本申请实施例的背光组件10可以通过一控制模组（图中未标示）分别对侧入入背光模组102以及高分子分散型液晶103进行控制。例如，该控制模组可以单独控制每一发光单元1023的发光状态，也即，该控制模组可以单独控制每一发光单元1023发光或者不发光。该控制模组还可以单独控制每一像素单元1034的状态，也即，该控制模组可以单独控制每一像素单元1034处于透明态或者处于暗雾提态。
进一步的，该发光单元1023以及该像素单元1034均呈长条状。在侧入式背光模组中102，每一发光单元1023均沿着第二方向延伸呈长条状，也即，该侧入式背光模组102被划分为多个沿第一方向排列的发光单元1023。在液晶盒103中，每一像素单元1034均沿着第一方向延伸呈长条状，也即，该液晶盒103被划分为多个沿第二方向排列的像素单元1034。
具体的，该侧入式背光模组102包括一导光板1022以及多个光源1021。导光板1022具有一出光面以及一入光面，出光面朝向液晶盒103设置，多个光源1021沿第一方向设置且朝向入光面。光源1021发出的光线射入导光板1022的入光面，再由导光板1022的出光面射入液晶盒103，当对高分子离散型液晶盒103施加电压时，高分子离散型液晶盒103呈现透明态，光线经高分子分散型液晶103盒射出；当没有对高分子离散型液晶盒103施加电压时，高分子离散型液晶盒103呈现暗雾态，光线不能经高分子液晶盒射出。
在一种实施例中，多个光源1021与多个发光单元1023一一对应，且每一光源1021经导光板1022形成一发光单元1023，每一发光单元1023的发光状态由对应的光源1021和液晶盒103控制。当然，为了提高发光效果，也可设置多个光源1021对应一个发光单元1023，每一发光单元1023的发光状态由对应的多个光源1021控制。
该液晶盒103包括：第一基板1031、第二基板1033以及设置在第一基板1031和第二基板1033之间的高分子分散型液晶层1032。其中，第一基板1031上设置有多个沿第二方向设置的第一像素电极（图中未标示），第二基板1033上设置有第一公共电极层（图中未标示），多个第一像素电极、高分子离散型液晶层1032以及第一公共电极层构成多个像素单元1034，每一像素单元1034对应一第一像素电极、第一像素电极对应的部分高分子离散型液晶层以及第一像素电极对应的部分第一公共电极层。
本申请实施例的背光组件可以在第一公共电极层上施加一预设电压，并通过单独控制每一像素单元1034对应的像素电极上的电压，进而控制每一像素单元的状态。
其中，高分子分散型液晶层1032又叫液晶调光膜，是将小分子液晶与高分子预聚物相混合，在一定条件下经聚合反应，形成微米级的液晶微滴均匀地分散在高分子网络中，再利用液晶分子的介电各向异性获得具有电光响应特性的材料，它主要工作在散射态和透明态之间并具有一定的灰度。
该高分子分散型液晶层1032为液晶小分子和高分子的混合层。该高分子分散液晶盒103通过第一公共电极层以及第一像素电极来驱动每一像素单元1034对应的高分子分散型液晶层1032的状态。当对高分子离散型液晶盒103施加电压时，高分子离散型液晶盒103呈现透明态；当没有对高分子离散型液晶盒103施加电压时，高分子离散型液晶盒103呈现暗雾态。
请参阅图3，图3为本申请实施例提供的背光组件的原理示意图。结合图1、图2、图3所示，多个发光单元1023与多个像素单元1034交叉设置形成多个背光区域104，每一背光区域104均可通过一发光单元1023与一像素单元1034控制。本申请实施例的背光组件10通过采用单独控制每一发光单元1023的发光状态以及每一像素单元1034的状态，实现对背光的二维分区控制，可以提高显示对比度，进而提高显示质量。
例如，如图3所示，该侧入式背光模组具有四个发光单元：第一个发光单元，第二个发光单元，第三个发光单元，第四个发光单元。该液晶盒具有四个像素单元：第一个像素单元，第二个像素单元，第三个像素单元，第四个像素单元。四个背光单元与四个像素单元交叉设置形成16个背光区域。第一个背光区域由第一个发光单元以及第一个像素单元控制，第二个背光区域由第一个发光单元以及第二个像素单元控制，……，以此类推。
其中，显示画面中亮度最大区域对应第一个背光区域，则通过控制第一个发光单元发光以及控制第一个像素单元处于透明态即可。具体的，在侧入式背光组件中仅驱动第一个发光单元对应的光源发光，在液晶盒中仅需提供第一个像素单元对应的像素电极电压，使的第一像素单元呈现透明态，其他像素单元则不加电压呈现暗雾态。
其中，若显示画面中亮度最大区域占据至少两个发光单元或者至少两个像素单元，则需要利用算法进行背光分区显示。
具体的，可以先判断显示画面的最大亮度区域是否对应处于同一背光区域上；若是，则通过控制侧入式背光模组以及液晶盒，使得相应的发光单元发光以及相应的像素单元处于透明态；若否，则通过控制侧入式背光模组以及液晶盒，按照显示画面的最大亮度区域对应的背光区域的面积大小依次使得相应的发光单元发光以及相应的像素单元处于透明态。
本申请实施例提供的背光组件，通过采用单独控制每一发光单元的发光状态以及每一像素单元的状态，实现对背光的二维分区控制，可以提高显示对比度，进而提高显示质量。
请参阅图4，图4为本申请实施例提供的显示面板组件的结构示意图。如图4所示，本申请实施例提供的显示面板组件30包括背光组件10以及设置在背光组件10上的显示面板20。其中，该背光组件10可参照以上的描述，在此不做赘述。
请参阅图5，图5为本申请实施例提供的显示面板组件的背光控制方法的流程示意图。该背光控制方法应用于以上所述的显示面板组件中，其中，多个发光单元与多个像素单元交叉设置形成多个背光区域，发光控制方法包括：
S101、判断显示画面的最大亮度区域是否对应处于同一所述背光区域上；
S102、若是，则通过控制所述侧入式背光模组以及所述液晶盒，使得相应的所述发光单元发光以及相应的所述像素单元处于透明态；
S103、若否，则通过控制所述侧入式背光模组以及所述液晶盒，按照显示画面的最大亮度区域对应的所述背光区域的面积大小依次使得相应的所述发光单元发光以及相应的所述像素单元处于透明态。
以上仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
