Description

液晶显示面板的配向方法 技术领域
本发明涉及一种液晶显示面板的制造方法，特别涉及一种液晶显示面板的配向方法。
 背景技术
在TFT-LCD生产中，液晶分子的配向目前主要采用两种配向方法，即摩擦配向和光配向。摩擦配向会产生静电和颗粒的污染，而光配向是一种非接触式的配向技术，其利用线偏振光照射在光敏感的高分子聚合物配向膜上，形成倾角，相对来说是一种较好的配向方法。
图1显示一种现有的光配向模式的示意图。如图1的（a）部分所示，在薄膜晶体管阵列基板侧，沿着像素的长边进行上下曝光配向，曝光的宽度为对应的像素的宽度的1/2；如图1的（b）部分所示，在彩膜基板侧，沿着像素的短边进行左右曝光配向，曝光的宽度为对应的像素的宽度的1/2。液晶分子的倾倒方向以图1的（c）部分的箭头方向来表示。图1的（d）部分和（e）部分显示出像素内部的暗纹，其中（d）部分为在没有黑矩阵下的模拟结果，（e）部分为在有黑矩阵下的模拟结果。
现有的光配向模式在像素内部会形成卍字暗纹，称万字暗纹，如图2所示。万字暗纹严重影响着像素的开口率，尤其是随着像素密度的提高，光穿透率成为光配向技术的瓶颈。
有鉴于此，有必要提出一种液晶显示面板的配向方法，以解决现有配向技术形成暗纹而影响光穿透率的技术问题。
 技术问题
本发明的目的在于提供一种液晶显示面板的制造方法，以解决现有配向技术导致光穿透率过低的技术问题。

 本发明的最佳实施方式
为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，本发明说明书所使用的词语“实施例”意指用作实例、示例或例证，并不用于限定本发明。
本发明提供一种液晶显示面板的配向方法，其从调整光配向曝光的宽度出发，借以改变暗纹的形状，减少暗纹的对光穿透率的影响，解决了现有配向技术导致光穿透率过低的技术问题。如图3所示，本发明中像素内部形成“ㄣ字暗纹”，相对于现有的光配向模式在像素内部形成的万字暗纹，暗纹的数量已明显减少，因此本发明所提供的液晶显示面板的配向方法能够显著地提高光穿透率。
首先对液晶显示面板的结构进行说明，请参阅图4，液晶显示面板包含第一基板（如薄膜晶体管阵列基板）10、第二基板（如彩膜基板）20以及配置于第一基板10和第二基板20之间的液晶层30，第一基板10的内侧表面形成有一第一配向膜11，第二基板20的内侧表面也形成有一第二配向膜21，第一基板10的第一配向膜11和第二基板20的第二配向膜21是用来对液晶层30的液晶分子进行配向，使得液晶分子依特定的方向与预定的倾斜角度排列，借此可提高面板的可视角度（Viewing Angle）。
图5显示本发明的液晶显示面板的配向方法的流程示意图，图7显示本发明的液晶显示面板的配向方法的示意图。请一并参阅图5和图7，本发明的液晶显示面板的配向方法包含如下步骤：
步骤S12：参考图7（a），于第一基板10侧，沿着像素的长度L的方向D1，对排成一列的像素对应的第一基板10上的第一配向膜11进行曝光配向，每次曝光的宽度S为像素宽度W的整数倍。举例来说，在图7所示的实施例中，每次对第一配向膜11曝光的宽度为S1，且S1与像素宽度W相等。
步骤S14：参考图7（b），于第二基板20侧，沿着像素的宽度W的方向D2，对排成一行的像素对应的第二基板20上的第二配向膜21进行曝光配向，每次曝光的宽度S为像素长度L的1/2的整数倍。举例来说，在图7所示的实施例中，每次对第二配向膜21曝光的宽度为S2，且S2为像素长度L的1/2。
步骤S12是制作第一基板10侧的第一配向膜11，步骤S14是制作第二基板20侧的第二配向膜21。在制作第一基板10侧的第一配向膜11时，光配向程序中，曝光的顺序是沿着列方向（也就是像素的长度方向D1）进行曝光，在每一列像素的曝光过程中，曝光的宽度S采用的是像素宽度W的整数倍，如1～8的整数倍， 具体如：曝光的宽度S为像素的宽度W。在制作第二基板20侧的第二配向膜21时，光配向程序中，曝光的顺序是沿着行方向（也就是像素的宽度方向D2）进行曝光，在每一行像素的曝光过程中，曝光的宽度S采用的是像素长度L的1/2的整数倍，如1～8的整数倍， 具体如：曝光的宽度S为像素的长度L的1/2。通过改变曝光的宽度S，可以改变暗纹的形状和大小，也因此能够调整光的穿透率，采用适当的曝光宽度S，也就能够提高光的穿透率。
在光配向程序中，若曝光的宽度越大，则可以预见能够得出越高的光穿透率，但是若曝光的宽度过大，则会影响面板的可视角度，因此曝光的宽度应有所限制。另外，于一实施例中，在制作薄膜晶体管阵列基板10侧的第一配向膜11时沿著像素的长度L的方向D1进行曝光，在制作彩膜基板20侧的第二配向膜21时沿着像素的宽度W的方向D2进行曝光；而于另一实施例中，在制作薄膜晶体管阵列基板10侧的第一配向膜11时沿著像素的宽度W的方向D2进行曝光，在制作彩膜基板20侧的第二配向膜21时沿着像素的长度L的方向D1进行曝光，也是可行的。
于其他实施例中，请一并参阅图6和图7，本发明实施例的液晶显示面板的配向方法包含如下步骤：
步骤S22：请参考图7（a），于第一基板10侧，对第一列的像素对应的第一基板10上的第一配向膜11，沿着纵向方向依序进行曝光配向。
步骤S24：请参考图7（a），于第一基板10侧，对与第一列相邻的第二列的像素对应的第一基板10上的第一配向膜11，沿着与所述纵向方向相反的方向依序进行曝光配向，其中在步骤S22和步骤S24中，每次曝光的宽度S为像素宽度W的整数倍。
在步骤S22和步骤S24中，是制作第一基板10侧的第一配向膜11，如图7的（a）部分所示，在光配向程序中，是进行上下曝光配向。也就是，针对第一列像素对应的第一配向膜11，是沿着纵向方向（如往下的方向）进行曝光配向；而针对与第一列相邻的第二列的像素对应的第一配向膜11，是沿着与纵向方向相反的方向（如往上的方向）进行曝光配向，如此完成第一配向膜11的整个配向动作。每次曝光的宽度S为像素宽度W的整数倍，如图7的（a）部分所示，每次曝光的宽度S基本上为像素的宽度W。
步骤S26：请参考图7（b），于第二基板20侧，对第一行的像素对应的第二基板20上的第二配向膜21，沿着横向方向依序进行曝光配向。
步骤S28：请参考图7（b），于第二基板20侧，对与第一行相邻的第二行的像素对应的第二基板20上的第二配向膜21，沿着与所述横向方向相反的方向依序进行曝光配向，其中在步骤S26和步骤S28中，每次曝光的宽度S为像素长度L的1/2的整数倍。
在步骤S26和步骤S28中，是制作第二基板20侧的第二配向膜21，如图7的（b）部分所示，在光配向程序中，是进行左右曝光配向。也就是，针对第一行像素对应的第二配向膜21，是沿着横向方向（如往右的方向）进行曝光配向；而针对与第一行相邻的第二行的像素对应的第二配向膜21，是沿着与横向方向相反的方向（如往左的方向）进行曝光配向，如此完成第二配向膜21的整个配向动作。每次曝光的宽度S为像素长度L的1/2的整数倍，如图7的（b）部分所示，每次曝光的宽度S基本上为像素长度L的1/2，也就是说，一个像素进行了两次横向曝光配向。
若步骤S22和步骤S24中，每次曝光的宽度S基本上为像素的宽度W，且步骤S26和步骤S28中，每次曝光的宽度S基本上为像素长度L的1/2，那么实验结果显示，本发明的液晶显示面板的配向方法相较于现有的配向方法，穿透率至少可以提高16.5%。
图7的（c）部分显示液晶分子受第一和第二配向膜11、21影响而呈现的倾倒方向，液晶分子整体的倾倒方向如图7的（c）部分中箭头所指出的方向，一个像素中液晶分子的倾倒方向如图7的（d）部分中箭头所指出的方向，图7的（d）部分也是在没有黑矩阵下对像素内部的暗纹的模拟结果，而图7的（e）部分是在有黑矩阵下对像素内部的暗纹的模拟结果。从模拟结果可以看出，本发明中像素内部形成“ㄣ字暗纹”，且暗纹占据的面积没有显著增加，因此，相较现有技术中的万字暗纹来说，光穿透率提高了。
本发明的液晶显示面板的配向方法通过于第一基板10侧，沿着像素的长边L的方向D1进行上下曝光配向，曝光的宽度S为像素宽度W的整数倍；并于第二基板20侧，沿着像素的短边W的方向D2进行左右曝光配向，曝光的宽度S为像素长度L的1/2的整数倍。本发明通过调整光配向曝光的宽度S来改变暗纹的形状，从而提高光穿透率过。相比于现有的光配向模式，采用本发明的液晶显示面板的配向方法，穿透率至少可以提高16.5%。
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。
