Description

液晶配向设备 技术领域
本发明涉及液晶生产技术领域，特别是涉及一种液晶配向设备。
 背景技术
液晶显示器(Liquid Crystal Display，LCD)已被广泛应用于各种电子产品中，液晶显示器大部分为背光型液晶显示器，其是由液晶显示面板及背光模块(backlight module)所组成。液晶显示面板是由两片透明基板以及被封于基板之间的液晶所构成。
目前，已发展一种垂直配向(Vertical Alignment, VA)技术，用于液晶显示面板。例如，由聚合物稳定垂直配向(polymer－stabilized alignment，PSA)制程所制造而成的聚合物稳定垂直配向型(Polymer Stabilized Vertical Alignment, PSVA)液晶显示器，其可具有广视角、高开口率、高对比及制程简单等优点。
在PSVA型液晶显示器中，两透明基板之间的液晶层内填充负性液晶分子，同时掺有反应型单体(reactive monomer)，反应型单体混合于负性液晶分子，其中，每一透明基板的表面涂布有聚酰亚胺(polyimide，PI)，其作为配向基材。接着，当施加电压及紫外光(UV)光照射于两透明基板时，反应型单体可与液晶分子发生相分离(phase separation)现象，而在透明基板的配向基材上形成聚合物。由于聚合物跟液晶分子之间的相互作用，液晶分子会沿着聚合分子的方向来排列，因此，透明基板之间的液晶分子可具有预倾角(pre-tile angle)。
其中，为保证液晶分子在紫外线光照射下形成预倾角而不产生带状色差（Mura），需要严格的控制紫外线线的照射均匀度，一般紫外线的照射均匀度需在10%左右。
请参阅图1，图1为现有技术中紫外线照射设备的一剖视结构示意图。
其中该紫外线照射配向设备包括顶部的光源板11，该光源板11上设置有长条型灯管111，长条型灯管111用于发射紫外光。光源板11的四侧设置有反射板12，反射板12相对光源板11呈一安装角度，该安装角度固定无法调整。而每一反射板12又包括上侧板121及下侧板122，且上侧板121及下侧板122的内表面平整，紫外光线通过上侧板121及下侧板122的反射后为平行光线，请参阅图2。
而随着灯管111的使用寿命的增加，灯管111两端的光线强度逐渐减弱，导致整个灯管111的光线强度中间高、两端低的现象。而从灯管111出射的光线经反射板12平行反射后，仍不能改变其均匀不一的问题，此会导致液晶分子被照射的均匀度不一，进而造成液晶分子配向后形成带状色差（Mura）现象。
因此，需解决现有技术中存在的上述技术问题。

请参照图3，图3为本发明提供的液晶配向设备的较佳实施例俯视结构示意图。
所述液晶配向设备包括光源发射板30，其具有相对平行设置的长侧边31和相对平行设置的短侧边32。所述液晶设备还包括有反射板，所述反射板具体包括长反射板41和短反射板42，其中所述长反射板41与所述光源发射板30的长侧边31连接，而所述短反射板42则与所述光源发射板30的短侧边32连接。
请参阅图4，图4为所述光源发射板30的结构示意图。所述光源发射板30上设置有多个光源33，光源33为长条型，用于发射紫外光。所述多个光源33平行于光源发射板30的长侧边31设置，且个个光源33之间以相等的间距D均匀排列，且该间距D在预设距离范围内，该预设距离的范围优选为200-220毫米（mm）。
在其它实施例中，所述光源发射板30的两长侧边32也可不平行设置，两短侧边33也可不平行设置，均在本发明保护范围内，此处不再一一详述。
请参阅图5，图5为沿图3中A-A'线的剖视结构示意图。所述长反射板41包括第一长反射板411和第二长反射板412。所述第一长反射板411与所述光源发射板30之间设置有第一转动装置51，所述第一长反射板411通过所述第一转动装置51与所述光源发射板30连接，且可第一长反射板411可相对于光源发射板30转动。所述第一长反射板411和所述第二长反射板412之间设置有第一旋转装置61，所述第二长反射板412通过所述第一旋转装置61与第一长反射板411连接，且可相对所述第一长反射板411旋转。
请参阅图6，图6为沿图3中B-B'线的剖视结构示意图。所述短反射板42包括第一短反射板421和第二短反射板422。所述第一短反射板421与所述光源发射板30设置有第二转动装置52，所述第一短反射板421通过所述第二转动装置52与所述光源发射板30连接，且可相对于光源发射板30转动。所述第一短反射板421和第二短反射板422之间设置有第二旋转装置62，所述第二短反射板422通过所述第二旋转装置62与所述第一短反射板421连接，且可相对于第一短反射板421旋转。
请参阅图7，图7为图5中所述第一转动装置51的分解结构示意图。所述光源发射板30设置有第一转轴511，所述第一长反射板411相应的设置有第一转筒512，所述第一转筒512为中空结构，所述第一转轴511可穿过所述第一转筒512，并可相对所述第一转筒512旋转，进而实现所述第一长反射板411相对所述光源发射板30的转动。所述第二转动装置52的结构与该第一转动装置51的结构类似，不再赘述。
请参阅图8，图8为图5中所述第一旋转装置61的分解结构示意图。所述第一长反射板411设置有第二转轴611，所述第二长反射板412相应的设置有第二转筒612，该第二转筒612为中空结构。所述第二转轴611可穿过所述第二转筒612，并可相对所述第二转筒612旋转，进而实现所述第二长反射板412相对所述第一长反射板411的转动。第二旋转装置62的结构与该第一旋转装置61的结构类似，不再赘述。
所述光源33发出的紫外光线中的大部分可直接照射至所述液晶层（图未示），其余部分则照射至反射板，照射至反射板的紫外光线经反射板的内表面反射后进入所述液晶层。
本发明中，所述反射板的反射面为凹凸不平的非平面结构，以所述第一长反射板411的反射面为例，请参阅图9，图9为光线经过所述第一长反射板411的反射面的行进路线示意图。该第一长反射板411的反射面凹凸不平，光源33发出的光线经所述第一长反射板411的反射面反射后，向多个方向散射。
由于本发明的反射板的反射面凹凸不平，射向所述反射板的紫外光线经所述反射板反射后，其前进路径呈分散状，形成漫反射，因此即便是光源33出射的紫外光线不均匀，但是经该反射板反射后，仍能够保证射向所述液晶层的紫外光线的均匀性，避免了配向过程中出现带状色差的现象，提高了产品良率，保证了液晶屏的显示效果。
请一并参阅图5，第一长反射板411与所述光源发射板30之间设置有第一转动装置51，因此所述第一长反射板411可通过所述第一转动装置51相对所述光源发射板30转动，因此本发明可灵活的调节所述第一长反射板411与所述光源发射板30法线（即垂直于光源发射板的射线）之间的夹角θ1，而且由于第二长反射板412与第一长反射板411之间设置有第一旋转装置61，因此所述第二长反射板412可通过所述第一旋转装置61相对所述第一长反射板411灵活转动，因此本发明可调节所述第一长反射板411与所述光源发射板30法线的夹角θ2。
同理，在图6中，所述第一短反射板421与所述光源发射板30法线之间的夹角θ3，以及所述第二短反射板422与所述光源发射板30法线之间的夹角θ4均可以自由调节，显然，本发明可通过调节各反射板与所述光源发射板30法线之间的夹角，来控制反射至所述液晶层的紫外光线，进一步的使得照射至所述液晶层的紫外光线均匀，避免了配向过程中出现带状色差的现象，以提高产品良率。
本发明通过将反射板的反射面设计为凹凸不平的形状，使得射向反射板的光线经反射面反射后，呈分散状射向液晶层，可以保证照射到液晶层的光线的均匀性，避免配向后形成带状色差，提高了产品的良率。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
