技术领域
本发明涉及液晶显示技术领域，特别涉及一种配向膜印刷版的补正系统及方法。
背景技术
目前在薄膜晶体管液晶显示屏(TFT-LCD)制程中，为了让液晶分子有固定预倾角，会在薄膜晶体管基板和彩膜基板(TFT/CF)两侧涂布配向膜(PI膜)。
在玻璃基板上涂布配向膜主要有两种方式：喷涂式(InkJet)以及印刷式(Print)，印刷式通常需要采取印刷版(APR版)。
印刷版采用树脂材料制成，如图1所示，随着印刷次数增加会拉伸，进而造成印刷版的图形变形，其中图1中的箭头方向为拉伸方向。所以随着印刷次数的增加，操作人员会观察印刷版上的图形变形，整体移动印刷的滚轮，使印刷版的图形得到整体补正，印刷起始方向较印刷末端由于拉伸程度不同，两者的图样偏移值也不一样，即如图2至图4所示，从印刷起始方向至印刷末端方向。各个位置处的拉伸程度不同，但整体补正为整体偏移，无法满足不同印刷位置拉伸程度不同而要求补正程度不同的需求，所以即使采用整体偏移对印刷版上的图像进行补正后，印刷版不同位置的配向膜图样依旧有不同程度的偏移，图1至图4中的实线为图样边界的原始位置，虚线为受到的拉伸情况。
为解决现有技术的问题，有必要提供一种新的配向膜印刷版的补正系统及方法。

具体实施方式
结合附图和本发明具体实施方式的描述，能够更加清楚地了解本发明的细节。但是，在此描述的本发明的具体实施方式，仅用于解释本发明的目的，而不能以任何方式理解成是对本发明的限制。在本发明的教导下，技术人员可以构想基于本发明的任意可能的变形，这些都应被视为属于本发明的范围，下面将结合附图对本发明作进一步说明。
图5至图7分别为本发明的印刷版与滚轮之间的连接示意图、印刷版的第一端部与第二端部相扣合的结构示意图和配向膜印刷版的补正方法的流程示意图。
如图5所示，本发明的印刷版1套设在滚轮2上，印刷版1包括第一端部11和第二端部12，且第一端部11和第二端部12通过连接部17连接起来。
图6是连接部17的放大图，第一端部11(印刷起始方向)上设有多列卡扣 组13，印刷版1的第二端部12(印刷末端方向)上设有多列与卡扣组13相配合的卡槽组14，本发明的配向膜印刷版的补正系统包括：图像控制器(图中未示出图像控制器)，其中，图像控制器用于测量基板上配向膜印刷的实际位置与预设位置之间的偏差值，操作人员根据图像控制器测量出的该偏差值来计算得出印刷版1的拉伸长度，操作人员根据该拉伸长度确定对印刷版的配向膜图样进行拉伸补正的程度。
具体的，卡扣组13包括至少一个卡扣凸起131，卡槽组14包括至少一个与卡扣凸起131相配合的卡扣凹槽141，通过卡扣凸起131与卡扣凹槽141相配合实现将印刷版的第一端部11和第二端部12连接起来，即本发明的印刷版1通过卡扣将第一端部11和第二端部12连接在一起，从而将印刷版1稳定地套设在滚轮2上，在本实施例中，卡扣组13包括一个卡扣凸起131，卡槽组14包括一个卡扣凹槽141，卡扣凸起131的个数和卡扣凹槽141的个数也可设计为其他个，在此不再具体限制。
进一步地，卡扣组13和卡槽组14上分别设有标尺，具体地，如图6所示，第一列的卡扣组13上的刻度为0、第二列的卡扣组13上的刻度为+1和第三列的卡扣组13上的刻度为+2，第一列的卡槽组14上的刻度为0、第二列的卡槽组14上的刻度为+1和第三列的卡槽组14上的刻度为+2，如图2至图4所示，由于靠近印刷起始端的印刷版拉伸程度小于靠近印刷末端的印刷版的拉伸程度，也即印刷版1的第一端部11的拉伸程度小于第二端部12的拉伸程度，因此，第一端部11的补正需求小于第二端部12的补正需求，根据图像控制器测量基板上配向膜印刷的实际位置与预设位置之间的偏差值来确定各个印刷方向的拉伸程度，操作人员根据该偏差值来选择卡扣组13和卡槽组14相配合的列数，具体地，当卡槽组14的+1刻度与卡扣组13的0刻度相扣合时，说明卡槽组14正方向前进一个单位，此时第二端部12受到的拉力大于第一端部11受到的拉力，即可以实现第二端部12的补正大于第一端部11的补正，从而达到提高印刷版的补正效果，且该补正不会需要额外的成本。
具体的，在本发明中，预设位置为基板与印刷版上设置的补正标识相对齐时的位置。
本发明的配向膜印刷版的补正方法，其包括以下步骤：S1)测量基板上配向膜印刷的实际位置，将该实际位置与该基板上配向膜印刷的预设位置进行对比计 算，得到偏差值；S2)根据该偏差值来对印刷版的配向膜图样进行不同程度的拉伸。
具体的，在本发明中，如图5和图6所示，本发明的印刷版1套设在滚轮2上，印刷版1的第一端部11(印刷起始方向)上设有多列卡扣组13，印刷版1的第二端部12(印刷末端方向)上设有多列与卡扣组13相配合的卡槽组14。
进一步地，卡扣组13包括至少一个卡扣凸起131，卡槽组14包括至少一个与卡扣凸起131相配合的卡扣凹槽141，通过卡扣凸起131与卡扣凹槽141相配合实现将印刷版的第一端部和第二端部连接起来，即本发明的印刷版1通过卡扣连接将第一端部11和第二端部12连接在一起，形成第一端部11和第二端部12相接的连接部17，从而将印刷版1稳定地套设在滚轮2上。
进一步地，卡扣组13和卡槽组14上分别设有标尺，具体地，如图6所示，第一列的卡扣组13上的刻度为0、第二列的卡扣组13上的刻度为+1和第三列的卡扣组13上的刻度为+2，第一列的卡槽组14上的刻度为0、第二列的卡槽组14上的刻度为+1和第三列的卡槽组14上的刻度为+2，当卡槽组14的0刻度与卡扣组13的+2刻度相扣合时，第一端部11和第二端部12受到的拉力相同，如图2至图4所示，由于靠近印刷起始端的印刷版拉伸程度小于靠近印刷末端的印刷版的拉伸程度，也即印刷版1的第一端部11的拉伸程度小于第二端部12的拉伸程度，因此，第一端部11的补正需求小于第二端部12的补正需求，根据图像控制器测量基板上配向膜印刷的实际位置与预设位置进之间的偏差值来确定各个印刷方向的拉伸程度，操作人员根据该偏差值来选择卡扣组13和卡槽组14相配合的列数，具体地，当卡槽组14的+1刻度与卡扣组13的0刻度相扣合时，说明卡槽组14正方向前进一个单位，此时有两列卡槽组14与两列卡扣组13相配合，且第二端部12受到的拉力大于第一端部11受到的拉力，即可以实现第二端部12的补正大于第一端部11的补正，从而达到提高印刷版的补正效果，且该补正不会需要额外的成本，如果需要进一步地增加第二端部12的补正效果，可将卡槽组14的0刻度与卡扣组13的0刻度相扣合，说明卡槽组14正方向前进两个单位，此时只有一列卡槽组14与一列卡扣组13相配合，从而实现进一步地增加第二端部12的补正效果，即本发明通过调整卡扣组13与卡槽组14相配合的列数来实现对印刷版1的配向膜图样进行不同程度的拉伸，相邻两列卡扣组13之间的距离可根据实际需要进行设定，在此不做具体限制。
本发明的配向膜印刷版的补正系统及方法通过对卡扣组13与卡槽组14相配合的列数来实现使印刷版的的配向膜图样得到不同程度的拉伸，从而达到采用不同程度地偏移对印刷版上的图像进行不同的补正，以使印刷版不同位置的配向膜图样上不存在不同程度的偏移。上述技术方案只是本发明的一种实施方式，对于本领域内的技术人员而言，在本发明公开了应用方法和原理的基础上，很容易做出各种类型的改进或变形，而不仅限于本发明上述具体实施方式所描述的方法。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。
