本发明涉及液晶显示技术领域，尤其涉及一种液晶面板的断线修复方法。The present invention relates to the technical field of liquid crystal display, and in particular, to a method for repairing broken wires of a liquid crystal panel.
背景技术Background technique
薄膜晶体管液晶显示器(TFT-LCD)是液晶显示器的一种，它具有低能耗、高亮度、高对比度、高响应速度、环保等特点，被广泛应用于电视、平板显示器及投影仪上。阵列工序是整个液晶显示制造流程中最核心的工序，制程工艺复杂度高、工期长、投资大，故阵列基板的良率至关重要。Thin-film transistor liquid crystal display (TFT-LCD) is a type of liquid crystal display. It has the characteristics of low energy consumption, high brightness, high contrast, high response speed, and environmental protection. It is widely used in TVs, flat panel displays and projectors. The array process is the core process in the entire liquid crystal display manufacturing process. The process has high complexity, long construction period and large investment, so the yield of the array substrate is very important.
阵列工序一般需经过多次“成膜-曝光-显影-蚀刻”完成阵列基板的制作，在透明玻璃基板上做成薄膜晶体管阵列，用来驱动液晶分子的旋转。制程工艺复杂，环境中异物很容易导致金属层断线，从而影响整个驱动控制电路正常导通。The array process generally requires multiple "film formation-exposure-development-etching" to complete the fabrication of the array substrate, and a thin film transistor array is formed on the transparent glass substrate to drive the rotation of the liquid crystal molecules. The manufacturing process is complicated, and foreign objects in the environment can easily lead to disconnection of the metal layer, thereby affecting the normal conduction of the entire drive control circuit.
现有技术中，阵列工序完成后金属层断线均利用激光化学沉积(Laser chemicalvapor deposition，LCVD)方式进行修复。激光化学沉积是金属源六羰 基钨W(CO)6在激光束作用下发生光解反应，分离出金属钨成膜在断线处，从而使信号线导通。In the prior art, after the array process is completed, the broken lines of the metal layer are repaired by means of laser chemical vapor deposition (LCVD). Laser chemical deposition is a photolysis reaction of metal source tungsten hexacarbonyl W(CO)6 under the action of a laser beam, and the metal tungsten is separated to form a film at the broken line, so that the signal line is turned on.
如图1所示，液晶面板的阵列基板包括矩阵状排列的第一像素区域01、第二像素区域02、第三像素区域03和第四像素区域04，位于同一列且相邻的第一像素区域01和第二像素区域02共用一条数据线11，针对跨像素区域数据线(source line)断线，数据线11的线缺陷110一部分位于第一像素区域01 内，一部分位于第二像素区域02内。As shown in FIG. 1 , the array substrate of the liquid crystal panel includes a
现行跨像素区域的数据线断线修复方法如图2所示，步骤简要地包括：The current method for repairing broken data lines across pixel areas is shown in Figure 2, and the steps briefly include:
步骤S11：找到跨像素区域的数据线线缺陷110的位置；Step S11: find the position of the
步骤S12：首先在线缺陷110两侧的数据线11上方使用激光打出修复通孔21，使数据线11暴露在表面；然后，利用激光化学沉积方式进行修复，形成连接桥22，连接桥22的两端分别与两个修复通孔21内的数据线11电性连接，使线缺陷110两侧的数据线11导通；Step S12: First, use a laser to punch repair through
步骤S13：使用激光在连接桥22外围剥除第一透明导电膜，形成剥除区域 23，剥除区域23一侧的连接桥22与剥除区域23另一侧的像素电极17断开。Step S13: use a laser to peel off the first transparent conductive film on the periphery of the connecting
该方法为本领域内通用修复手法，修复成功率约90％，修复失败可能形成多连结，多连结是指3个或3个以上相邻像素区域出现暗点或者亮点缺陷。步骤S12在镀膜时金属溅射或者步骤S13中剥除区域23处的像素电极17剥除不干净可能导致第一像素区域01和第二像素区域02变成亮点。若周边像素区域有异常(以第三像素区域03、第四像素区域04为例)，就会形成多连结，导致液晶面板报废。This method is a common repair method in the field, and the repair success rate is about 90%. If the repair fails, multiple connections may be formed. Multi-connection refers to the occurrence of dark or bright defects in three or more adjacent pixel regions. Metal sputtering during coating in step S12 or unclean peeling of the

如图3所示，本发明的跨像素区域数据线11断线的修复方法包括以下步骤：As shown in FIG. 3 , the method for repairing the disconnection of the
首先，按照现有步骤在阵列工艺段完成镀膜架桥修补，阵列工艺段在阵列基板的正面进行，包括：First, complete the coating bridge repair in the array process section according to the existing steps, and the array process section is carried out on the front side of the array substrate, including:
步骤S31：找到跨像素区域的数据线线缺陷110的位置(即线缺陷110位于数据线11的上方)；Step S31: Find the position of the
步骤S32：在线缺陷110两侧的数据线11上方使用激光打穿绝缘膜以形成位于数据线11上的修复通孔21，通过修复通孔21使数据线11暴露在表面，利用激光化学沉积方式形成连接桥22，导电的连接桥22连接位于线缺陷110 两侧的数据线11；Step S32 : using a laser to punch through the insulating film on the data lines 11 on both sides of the
