液晶面板的生产制造过程整体可以分为以下几个大的流程：一、阵列图案制作流程；二、定向制作流程；三、盒的制作流程；四、液晶面板的切灌（液晶）流程；五、液晶面板的质量检查流程。
其中，所述定向制作流程具体包括如下过程：在玻璃基板上按要求涂上一层定向膜，并通过绒布对定向膜表面进行摩擦，在定向膜表面形成定向沟槽。然后对形成定向沟槽的定向膜进行固化，从而得一定的预倾角，此时定向制作流程即完成。
另外，现有技术中，定向制作流程也可以在液晶面板的切灌（液晶）制作流程之后。但具体的定向制作流程与上述制作流程有所不同。同时还需在液晶面板的切灌（液晶）制作流程，在灌入的液晶中添加填充材料。其具体的定向制作过程如下:在切灌制作完成后，对液晶面板充电，使液晶旋转到一定的角度，然后通过紫外线照射，使液晶中的填充材料固化，从而得到一预倾角。
上述第二种定向制作流程中，由于采用的紫外线其波长范围宽，照射过程产生填充材料不良的影响，且填充材料所需照射时间长，影响了液晶面板的生产制作速度和效率。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。在此必需先说明的是，基于描述上的方便，各图中已省略了与本说明较无关系的组件，而以一种示意图的方式来呈现。
参见图1，图1提出本发明一种液晶面板预倾角的制作装置100的一实施例。该液晶面板预倾角的制作装置100包括一样品台110与至少一紫外线光源120，样品台110用于放置液晶面板140，紫外线光源120用于照射液晶面板140，以固化旋转至设定角度的液晶层中的填充物，形成预倾角；样品台110和紫外线光源120之间设置有紫外线过滤板130，该紫外线过滤板130只透过波长为320nm至380nm的紫外线。
进一步地，上述液晶面板预倾角的制作装置100实施例中，所述紫外线光源120照射区域的面积小于或等于所述紫外线过滤板130的上表面面积，以保证液晶面板接收到的所有紫外线都经由所述紫外线过滤板。
进一步地，上述液晶面板预倾角的制作装置100实施例中，所述紫外线光源120的输出功率为85nW。
所述液晶面板140包括TFT（Thin Film Transistor ，薄膜场效应晶体管)基板141与CF（color filter，彩色滤光片）基板142，其中，TFT基板141和CF基板142之间设置有液晶层（图中未画出），该液晶层是由液晶和填充物均匀混合而成的。所述填充物在紫外线的照射下会固化。当液晶面板140通电，并设定好固定电压，则液晶带动填充物旋转至设定角度。此时填充物在紫外线照射下固化，从而形成了固定的预倾角。其中，填充物在不同波长的紫外线照射下，其固化时间不同，固化效果不同。当在波长为320nm至380nm的紫外线照射下，固化时间最短，且固化效果最佳。
进一步地，当将液晶面板140置于所述样品台110上进行预倾角制作时，所述液晶面板140中的TFT基板141朝上。在其他的变更实施例中，当将液晶面板140置于所述样品台110上进行预倾角制作时，所述液晶面板140中的CF基板142也可朝上。
上述液晶面板预倾角的制作装置100实施例中，采用在样品台110和紫外线光源120之间设置紫外线过滤板130，使波长为320nm至380nm的紫外线透过紫外线过滤板照射液晶面板140的方式，缩短了液晶面板预倾角的制作时间，提高了液晶面板预倾角的固化效果。
参见图2，图2提出本发明一种样品台200的一实施例。该样品台200包括用于放置液晶面板140的样品台本体210，所述样品台本体210上设置有紫外线过滤罩211，该紫外线过滤罩211只透过波长为320nm至380nm的紫外线，所述样品台本体210和紫外线过滤罩211形成的空间用于纳置液晶面板140。
进一步地，上述样品台200实施例中，所述紫外线过滤罩211的顶壁内表面形状与液晶面板140的平面形状一致。
进一步地，上述样品台200实施例中，所述紫外线过滤罩211顶壁内表面积大于液晶面板140的平面面积。
进一步地，上述样品台200实施例中，其特征在于，所述紫外线过滤罩211顶壁内表面积等于液晶面板140的平面面积。
本实施例提供的样品台200，应用于液晶面板预倾角的制作过程中，即在液晶面板预倾角的制作过程中，将已通电的液晶面板140置于该样品台200的样品台本体210和紫外线过滤罩211形成的空间内，再通过普通的紫外线光源进行照射；由于液晶面板140置于样品台本体210和紫外线过滤罩211形成的空间内，液晶面板140接收到的所有紫外线都经由紫外线过滤罩211。即所接收的紫外线的波长为320nm至380nm，使通过液晶带动旋转至设定角度的填充物快速固化，从而可以缩短液晶面板预倾角的制作时间，同时可以提高液晶面板预倾角的固化效果。
参见图3，图3提出本发明一种光源装置300的一实施例。该紫外线光源装置300包括紫外线发光灯体310，罩设在该紫外线发光灯体310外围的防护罩320，与所述防护罩320连接设置的紫外线过滤罩330。该紫外线过滤罩330只透过波长为320nm至380nm的紫外线，所述紫外线发光灯体310置于所述防护罩320和紫外线过滤罩330形成的空间内，使被照射物件接收到的所有紫外线都经由所述紫外线过滤罩330。
进一步地，上述光源装置300实施例中，所述防护罩320与所述紫外线过滤罩330为无缝连接，使紫外线发光灯体310置于所述防护罩320和紫外线过滤罩330形成的密闭空间内。
进一步地，上述光源装置300实施例中，所述紫外线发光灯体310的输出功率为85nW。
本实施例提供的光源装置300，应用于液晶面板预倾角的制作过程中，即在液晶面板预倾角的制作过程中，将已通电的液晶面板140置于本实施所提供的光源装置300下进行照射。由于该光源装置300设置有紫外线过滤罩330，液晶面板140接收到的所有紫外线都经由紫外线过滤罩330，即所接收的紫外线的波长为320nm至380nm，使液晶面板140中通过液晶带动旋转至设定角度的填充物快速固化，从而可以缩短液晶面板预倾角的制作时间，同时可以提高液晶面板预倾角的固化效果。
参见图4，图4提出一种液晶面板预倾角的制作方法的一实施例，该制作方法基于前述图1实施例中液晶面板预倾角的制作装置的结构。该制作方法包括：
步骤S101、在样品台和紫外线光源之间设置紫外线过滤板；
步骤S102、将一液晶面板置于样品台上；
所述液晶面板处于充电状态，薄膜场效应晶体管基板与彩色滤光片基板之间的液晶层，旋转至设定的角度；
步骤S103、采用透过该紫外线过滤板的波长为320nm至380nm的紫外线照射所述液晶面板，以固化液晶层中的填充物，形成预倾角。
上述液晶面板预倾角的制作方法实施例中，所述填充物在不同波长的紫外线照射下，其固化时间不同，固化效果不同。当在波长为320nm至380nm的紫外线照射下，固化时间最短，且固化效果最佳。
进一步地，上述液晶面板预倾角的制作方法实施例中，所述紫外线光源的照射区域面积小于或等于所述紫外线过滤板的上表面面积，以保证液晶面板接收到的所有紫外线都经由所述紫外线过滤板。
进一步地，上述液晶面板预倾角的制作方法实施例中，所述紫外线光源的输出功率为85nW。
进一步地，上述液晶面板预倾角的制作方法实施例中，所述液晶面板置于样品台时，液晶面板中的TFT基板朝上。在其他的变更实施例中，当将液晶面板140置于所述样品台110上进行预倾角制作时，所述液晶面板140中的CF基板142也可朝上。
上述液晶面板预倾角的制作方法实施例中，通过在样品台和紫外线光源之间设置紫外线过滤板，使波长为320nm至380nm的紫外线透过紫外线过滤板照射液晶面板的方式，缩短了液晶面板预倾角的制作时间，提高了液晶面板预倾角的固化效果。
应当理解的是，以上仅为本发明的优选实施例，不能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。
