技术领域
本发明涉及液晶显示器制造技术领域，特别涉及一种框胶固化用的掩膜板。
背景技术
液晶显示器(LCD，Liquid Crystal Display)是一种被广泛应用的平面显示装置，随着人们对于显示装置的需求的增加，液晶显示器制造领域的技术革新也是非常迅速的。在现有技术中，一般的液晶面板结构如图1所示，包括平行设置的第一基板1和第二基板2，以及设置在第一基板1和第二基板2周边的胶框3，胶框3用于将第一基板1和第二基板2粘结在一起，在第一基板1和第二基板2之间注入液晶得到液晶区域4，液晶区域4靠近中心的位置为有效显示区5，液晶区域4中除了有效显示区5以外的部分为非有效显示区6。第一基板1上设置有薄膜场效应晶体管(TFT，Thin Film Transistor)的基板，第二基板2为彩膜(CF，Color Filter)基板，通过TFT上的信号与电压改变来控制液晶盒中液晶分子的转动方向，从而达到控制每个像素点偏振光出射与否而达到显示目的。
其中胶框3的作用是防止第一基板1和第二基板2之间的液晶材料流出。在液晶盒的制造过程中，胶框3由框胶固化得到，因此框胶固化是液晶制造过程中非常重要的一个步骤。现有技术中，UVC(ultra violet curing)是一种常用的框胶固化方法。如图1所示，在使用UV(ultra violet)光固化框胶时，需要在玻璃基板的上方放入掩膜板(UV Mask)遮蔽玻璃基板中的液晶区域4，防止液晶分子受到UV光的照射导致液晶分子分解或者变性。掩膜板(UV Mask)通常是玻璃板7上蒸镀一层金属层，金属层8与玻璃板7共同构成掩膜板9，掩膜板9用来 遮蔽紫外光源10对于液晶区域的照射。掩膜板9的作用主要是保护有效显示区5不受到紫外光的照射。
图2为在掩膜板一侧，沿垂直掩膜板的方向观察到的掩膜板与显示面板位置关系的示意图，为了说明掩膜板的作用原理，在图2中仅仅保留了掩膜板9的金属层8、有效显示区5以及胶框3三部分，其他部分省略在图2中未示出，这样的省略对于本领域技术人员来说是清楚的。图2中虚线框部分为有效显示区5，有效显示区5为液晶面板的显示部分，图中最外侧的胶框3围绕有效显示区设置，有效显示区5与胶框3均为显示面板的一部分，因此处于在同一平面；由图1和图2可知，掩膜板9的遮蔽层8位于与显示面板平行的另一个平面，图2中所示的遮蔽层8的边缘为遮蔽层8在显示面板所在平面上的投影。如图2所示，其中胶框3的内边缘与有效显示区5的边缘之间的距离为a，有效显示区5的边缘与金属层8的边缘在显示面板所在平面上的投影之间的距离为b，金属层8的边缘在显示面板所在平面上的投影与胶框内边缘的距离为c。
在实际的操作中，通常有以下问题需要考虑：(1)框胶固化用的机台上会有一定的对位精度误差，(2)掩膜板本身有一定的制作误差，(3)紫外光有一定的散射，紫外光的散射有可能会造成液晶的分解。考虑到上述问题，其中的a、b和c的大小均有一定的要求。现在随着液晶面板技术的发展以及人们对于液晶面板的要求，液晶面板的边框越来越窄。当边框变窄时，即图2中的a变小。a变小必然造成b和/或c要变小。如果b过小，由于金属层8的面积相对减小，液晶有效显示区的液晶受到UV的照射时，可能会造成液晶的分解；当c过小时，由于金属层8对框胶可能会有一定的遮蔽，从而造成框胶的固化不完全。基于现有技术中的掩膜板的结构，面对显示面板边框越来窄的情况，现有技术中的掩膜板的缺陷会越来越明显，因此，现有技术中的掩膜板存在无法应对显示面板越来越窄的情况。
发明内容
为了解决现有技术中的掩膜板无法应对显示面板越来越窄的情况的技术问题，本发明提出了一种框胶固化用的掩膜板。
本发明提出一种框胶固化用的掩膜板，包括支撑板，所述支撑板为平板结构，所述平板结构包括第一平面和第二平面，所述第一平面上设置有遮蔽层，所述支 撑板为透明结构，所述遮蔽层允许部分光透过；使用时，掩膜板与涂有待固化框胶的液晶面板平行放置，固化框胶用的光透过掩膜板照向液晶面板。
本发明利用框胶所使用的材料固化所需要的光照强度与液晶分解所需要的光照强度之间的区别，将掩膜板的遮蔽层设置为允许部分光透过的结构，在保证框胶可以正常固化的情况下，同时保证液晶不会因为受到光照而发生分解。因此，在显示面板边框变窄的情况下，本发明中的框胶固化用的掩膜板也可以很好地应对，避免框胶固化不完全以及液晶分解的情况的产生。
作为对本发明进一步的改进，所述遮蔽层包括完全遮蔽区域和部分遮蔽区域，所述完全遮蔽区域位于所述遮蔽层中心位置，所述部分遮蔽区域围绕所述全遮蔽区域设置，所述部分遮蔽区域允许部分光线透过，使用时所述完全遮蔽区域与液晶面板的有效显示区对应设置，所述完全遮蔽区域用于遮挡照向有效显示区的光线。
将遮蔽层划分为完全遮蔽区域和部分遮蔽区域，其中的完全遮蔽区域对应有效显示区进行设置，避免了较弱的光强对与液晶可能产生的影响，进一步保证了本发明中的框胶固化用的掩膜板对于有效显示区的液晶的保护作用。
作为对本发明进一步的改进，所述部分遮蔽区域为在遮蔽层上设置有透光结构，所述透光结构允许光线透过，使用时，所述部分遮蔽区域与液晶面板的非有效显示区以及待固化框胶对应设置。
作为对本发明进一步的改进，所述透光结构为贯穿遮蔽层设置的孔状结构。
作为对本发明进一步的改进，所述孔状结构圆形或多边形。
作为对本发明进一步的改进，所述透光结构为环绕完全遮蔽区域设置的环状透光孔。
作为对本发明进一步的改进，所述部分遮蔽区域用于遮蔽部分照向液晶面板上的待固化框胶的光线；使用时，所述待固化框胶靠近液晶面板中心的部分位于所述部分遮蔽区域下侧。待固化框胶部分位于部分遮蔽区域的下侧，这样在没有遮蔽层的位置的光线可以对框胶进行完全的照射，从而使得框胶的固化效果更好，固化时间更短，降低固化成本。
作为对本发明进一步的改进，部分遮蔽区域光线透过率为30％～70％。光线透过率可以根据具体的需要进行选择，在现行采用的框胶以及液晶的材料的性质，30％～70％的透光率是合理的。
作为对本发明进一步的改进，所述遮蔽层为金属层。用金属层作为遮蔽层，遮光性好，技术成熟。
作为对本发明进一步的改进，所述支撑板为玻璃材质。玻璃作为一种常用的可透光材质，取材方便，成本低廉。
总之，本发明由于将掩膜板的遮蔽层设置为允许部分光透过的结构，在保证框胶可以正常固化的情况下，同时保证液晶不会因为受到光照而发生分解。因此，在显示面板边框变窄的情况下，本发明中的框胶固化用的掩膜板也可以很好地应对，避免框胶固化不完全以及液晶分解的情况的产生。

具体实施方式
以下将结合附图对本发明的内容作出详细的说明，下文中的“上”“下”“左”“右”均为相对于图示方向，不应理解为对本发明的限制。
在目前液晶面板材料中，框胶所使用的材料开始固化所需要的紫外光的最低照度比较低，而液晶材料受到照射开始分解的需要的紫外光的照度比较高，基于上述差异，本发明提供的框胶固化用的掩膜板结构可以很好的解决现有技术中存在的问题。通过将遮蔽层设置为允许部分光透过的结构，从而控制通过遮蔽层32的光的强度，使得通过遮蔽层32的光强可以固化框胶，同时又不会对液晶造造成伤害。
实施例一
如图3所示，为本实施例中的框胶固化剖面示意图，为了便于说明本实施例 中的框胶固化用的掩膜板30进行说明，将现有技术中常见的液晶面板结构与框胶固化用的掩膜板30之间的结构关系进行了显示，其中液晶面板的具体结构与图1中所示的结构基本相同，并且在图3中也如图1中一样，示意出了用于固化框胶的紫外光源10，在此不再赘述。本实施例中的框胶固化用的掩膜板30，包括支撑板31，支撑板31为透明的平板结构，平板结构包括第一平面311和第二平面312，第一平面311上设置有遮蔽层32，遮蔽层32允许部分光透过；使用时，掩膜板与涂有待固化框胶的液晶面板平行放置，固化框胶用的光线透过框胶固化用的掩膜板30照向液晶面板。
如图4所示为本实施例中的框胶固化用的掩膜板的主视图。结合图3和图4，可以看出本实施中的遮蔽层32的部分透光作用是通过以下结构实现的，遮蔽层32包括完全遮蔽区域321和部分遮蔽区域322，完全遮蔽区域321位于遮蔽层32中心位置，部分遮蔽区域322围绕全遮蔽区域321设置，使用时完全遮蔽区域321与液晶面板的有效显示区5对应设置，有效显示区5位于完全遮蔽区域321下侧，完全遮蔽区域用于遮挡照向有效显示区5的光线，光线完全无法照向有效显示区5，从而保护有效显示区的液晶材料。
在本实施例中，完全遮蔽区域域321为矩形结构，该矩形结构是与显示面板的结构相对应的，在本实施例的基础上，本领域技术人员可以根据实际的显示面板的形状对完全遮蔽区域321进行设置；其中的部分遮蔽区域322(图3中的虚线框部分)是在遮蔽层的基础上开出一些贯穿遮蔽层32的孔状的结构，孔状结构允许光线通过，孔状结构是围绕矩形结构设置的，如图3和图4所示，本实施中的孔状结构为围绕矩形结构的环状透光孔3221，在图3和图4中仅仅示出了三个环状透光孔3221，本实施中为了对发明进行说明，不表示实际的环状透光孔3221的个数，在实际使用中，可以根据具体的尺寸以及透光要求进行设置。
优选的，由于部分遮蔽区域322用于遮蔽液晶面板上的待固化框胶，待固化框胶靠近液晶面板中心的一部分位于部分遮蔽区域322的下侧。即待固化框胶有一部分是可以完全暴露在固化光线以下的，这样的设置更加有利于框胶的固化。
需要说明的是，图4为本实施例中本实施例中的框胶固化用的掩膜板的主视图，为了清楚地显示本实施例中的环状透光孔3221，在遮蔽层32上不属于环状透光孔3221的部分用图案进行了填充，因此，该填充仅仅是为了区分遮蔽层32可透光部分与不透光部分，而不应视作是遮蔽层32的剖视图。
实施例二
如图5所示为本实施例中的框胶固化用的掩膜板的主视图，本实施例与实施例一的区别在于部分遮蔽区域322的具体结构的不同，其他部分与实施例一中相同，在此不再赘述。
在本实施例中，部分遮蔽区域322允许部分光透过的作用由设置在遮蔽层上的透光结构完成。如图5所示，透光结构为贯穿遮蔽层32设置的孔状结构。在本实施例中选用的是圆形孔状结构51，圆形孔状结构在制造上比较方便。
优选的，圆形孔状结构51在部分遮蔽区域322均匀分布。
优选的，可以在靠近完全遮蔽区域321的部分分布较少的圆形孔状结构51，在离完全遮蔽区域321较远的部分分布较多的圆形孔状结构51。具体的，可以在位于非有效显示区6上方的部分设置较少的圆形孔状结构51，在待固化框胶上方的位置设置较多的圆形孔状结构51。这种非均匀的设计方法可以使得框胶得到胶充足的光的照射，同时进一步减少的光对于液晶的影响。
当然，孔状结构也可以设置为其他形状的孔，例如可以为矩形、椭圆形、三角形以及其他常见的形状，在此不再赘述。
在图5中在遮蔽层32上不属于圆形孔状结构51的部分用图案进行了填充，因此，该填充仅仅是为了区分遮蔽层32可透光部分与不透光部分，而不应视作是遮蔽层32的剖视图。
优选的，本发明中针对于部分遮光区域，其中透光结构的面积与部分遮光区域其他部分的面积比值为光线的透过率，在本发明中，部分遮蔽区域光线透过率为30％～70％，在一些实施例中，进一步优选的为50％～60％。具体的透过率的选择根据框胶材料以及液晶材料的不同，本领域技术人员根据本发明的内容可以进行适当的选择，在此不再赘述。
优选的，遮蔽层32的材质一般选用常见的金属即可，只要该金属层可以隔绝光线的通过即可，所述光线常用的为紫外光。
优选的，支撑板31的作用是支撑遮蔽32，因此，支撑板31需要为透明结构，允许光线透过，一般常用的为玻璃材质。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起 来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
