技术领域
本公开的实施例涉及液晶面板的制造领域，尤其涉及对液晶面板中的配向层进行摩擦的方法，以及使用该方法制造的液晶面板。
背景技术
在现有的生产工艺中，在液晶面板的包括彩膜基板和阵列基板的玻璃基板上涂布诸如聚酰亚胺(PI)之类的配向膜(也称为取向膜或定向膜等)，该配向膜可以给液晶分子提供一个预倾角，然后采用贴附有摩擦布的辊对配向膜进行摩擦以在其表面形成沿一定方向排列的沟槽，该沟槽对液晶分子起到锚定的作用，可以使未加电状态下的液晶分子沿一定方向排列。这样，在液晶显示技术中，再通过电场控制液晶分子的偏转方向，以此控制背光源产生的光线经过液晶面板时的透光率，使液晶面板显示出不同的亮度。

进一步地，基板相对于辊的水平移动方向与辊底部的切线速度方向相 反。
进一步地，第一方向为顺时针，第二方向为逆时针。
进一步地，第一方向为逆时针，第二方向为顺时针。
进一步地，沿第一方向旋转时的摩擦布毛压入深度与沿第二方向旋转时的摩擦布毛压入深度不同。
进一步地，沿第一方向旋转时的摩擦布毛压入深度小于沿第二方向旋转时的摩擦布毛压入深度。
本公开还提供了一种根据上述方法制造的显示面板。
通过本公开提供的摩擦配向方法，可以使摩擦布毛与像素边缘两侧的段差部分都能有效接触，从而形成均匀有效的配向，确保像素边缘不会因液晶分子无序排列而产生漏光现象，从而可以实现防漏光、显示效果好的显示面板。
附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本公开的一些实施例，而非对本公开的限制。对于本领域普通技术人员来讲，还可以根据这些附图获得其它附图。当结合附图阅读时，通过参照以下对说明性实施例的详细描述，将更好地理解本公开实施例的各个方面及其进一步的目的和优点，在附图中：
图1是根据本公开的示例性实施例的摩擦配向方法的示意图。
具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
贯穿本说明书全文，谈及特征、优点或类似的措辞并非意味着可以利用本公开而实现的所有特征与优点应当在或者是在本公开的任何单个的实施例中。相反，要理解涉及特征与优点的措辞意味着结合实施例所描述的具体特征、优点或特性包括在本公开的至少一个实施例中。因而，贯穿本说明书全文，对特征和优点的讨论以及类似的措辞可以指同一实施例，但却不一定指同一实施例。此外，所描述的本公开的特征、优点以及特性可以用任何合适的方式合并在一个或多个实施例中。相关领域的技术人员将会认识到，可以在没有特定实施例的一个或多个具体特征或优点的情况下实践本发明。在其它的示例中，可以在某些实施例中实现附加的特征和优点，其不一定出现于本公开的所有实施例之中。
在本公开的描述中，需要说明的是，术语“上”、“下”、“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，在本公开的描述中，除非另有说明，“多个”的含义是两个或两个以上。
但是，在一种生产工艺中，通常使贴附有摩擦布的辊沿单一方向旋转，这使得像素边缘一侧的段差部分由于被信号线遮挡而导致无法与摩擦布毛有效接触，因此无法形成均匀的有效的配向，成盒后液晶分子在此位置排布杂乱，无法有序排列，进而导致像素边缘产生漏光现象。
图1是根据本发明的示例性实施例的摩擦配向方法的示意图。为了简明起见，在图1中没有示出贴附有摩擦布的辊的整体，而只是示出了对配向膜起摩擦作用的摩擦布毛1。本实施例中的涂布有配向膜的基板是以图1所示的阵列基板2为例，但是，本发明不限于此，也可适用于液晶面板中的彩膜基板。在本实施例中，在摩擦配向中对像素边缘一侧的段差部分进行遮挡的信号线是以图1所示的数据线3为例，但是，本发明不限于此，也可适用于信号线例如为扫描线等的情况。
图1所示的本实施例的摩擦配向方法包括以下步骤：
步骤S1，在涂布有配向膜(未示出)的阵列基板2相对于贴附有摩擦布的辊(未示出)水平移动的过程中，使该辊沿第一方向旋转，以便摩擦布毛1对该配向膜进行摩擦；
步骤S2，在涂布有配向膜的阵列基板2相对于贴附有摩擦布的辊水平移动的过程中，使该辊沿第二方向旋转，以便摩擦布毛1对该配向膜进行摩擦。
如图1所示，在本实施例的步骤S1中，第一方向为顺时针方向，即，贴附有摩擦布的辊沿顺时针方向旋转；在本实施例的步骤S2中，第二方向为逆时针方向，即，贴附有摩擦布的辊沿逆时针方向旋转。但是，本发明不限于此，第一方向也可以为逆时针方向，而第二方向为顺时针方向，等等，只要满足第一方向与第二方向相反即可。
关于涂布有配向膜的阵列基板2相对于贴附有摩擦布的辊的水平移动，可以是在阵列基板2水平移动的情况下，该辊仅旋转而不在水平方向上滚动，也可以是在阵列基板2不水平移动的情况下，该辊在水平方向上滚动，等等，只要满足阵列基板2相对于该辊水平移动即可。另外，阵列基板2的移动可以通过承载基板的基台(未示出)的移动来实现。
进一步地，涂布有配向膜的阵列基板2相对于贴附有摩擦布的辊的水平移动方向与该辊底部的切线速度方向相反，这样即使在该辊的低转速范围内，也可以在如图1所示的步骤S1和S2中分别保持各自的摩擦布毛摩擦方向，从而分别确保步骤S1和S2中的统一配向，以便最终形成均匀有效的配向。
例如，在图1所示的步骤S1中，在贴附有摩擦布的辊沿顺时针方向旋转的情况下，涂布有配向膜的阵列基板2相对于该辊的水平移动方向可以是从左到右的方向；在图1所示的步骤S2中，在贴附有摩擦布的辊沿逆时针方向旋转的情况下，涂布有配向膜的阵列基板2相对于该辊的水平移动方向可以是从右到左的方向。
如图1的步骤S1所示，在像素边缘两侧的段差部分中的区域A1和A2中，区域A1与摩擦布毛1有效接触，然而，区域A2因为数据线3的 遮挡而不能与摩擦布毛1有效接触。如图1的步骤S2所示，区域A2与摩擦布毛1有效接触，虽然区域A1因为数据线3的遮挡而不能与摩擦布毛1有效接触，但是区域A1已经在之前的步骤S1中与摩擦布毛1有效接触。因此，图1所示的涂布有配向膜的阵列基板2最终能形成均匀有效的配向。
进一步地，在图1所示的步骤S1和S2中，可以调整摩擦布毛压入深度，使在配向膜上形成的沟槽相同，从而使液晶分子的预倾角角度相同，以便确保涂布有配向膜的阵列基板2最终能形成统一、均匀、有效的配向。另外，摩擦布毛压入深度的调整可以借助升降机构，通过调整贴附有摩擦布的辊的垂直方向上的高度，或者通过调整承载基板的基台(载台)的高度，或者通过调整对该辊的纵向压力等来实现。
例如，步骤S1和S2中的摩擦布毛压入深度可以被设定为相同，也可以被设定为不同，例如，步骤S1中的摩擦布毛压入深度可以小于步骤S2中的摩擦布毛压入深度，或者，步骤S1中的摩擦布毛压入深度可以大于步骤S2中的摩擦布毛压入深度，都是为了确保涂布有配向膜的阵列基板2最终能形成统一、均匀、有效的配向。
关于以上步骤S1和S2，也可以分别重复执行，直至涂布有配向膜的阵列基板2最终能形成统一、均匀、有效的配向。
如上所述，本发明不限于此，也可适用于液晶面板中的彩膜基板，因此，可以按照与上述实施例类似的方法摩擦涂布有配向膜的彩膜基板，从而实现统一、均匀、有效的配向。通过这样的摩擦配向工艺，可以制造防漏光、显示效果好的液晶面板。
以上结合附图描述了根据本公开的示例性实施例，但这仅仅是为了说明和解释本发明的构思而采用的示例性和示意性说明，而不是对本发明的各方面进行限制。本领域的技术人员应该理解，在不脱离本发明的精神和本质的情况下，可以做出各种修改和变型，这些修改和变型均落在本发明的保护范围内。以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本发明的保护范围由所附的权利要求确定。
