根据该扫描结果, 将所述补线路径分成多个路径区间, 并为所述每一段 路路径区间设置对应的镀膜速度; 如图 4中, 可以将该补线路径分为七段,
分别为 a-b段、 b-c段、 c-d段、 d-e段、 e-f段、 f-g段、 g-h段。 其中, a-b 段、 b-c段、 d-e段、 f-g段、 g-h段中高度变化不大, 可以将各路径区间的镀 膜速度设为相同或大致相同, 而的 c-d段、 e-f段中高度变化很大, 可以将其 对应的 t 速度设置为更慢的镀膜速度。
或者, 可以根据对补线路径的扫描结果, 直接确认补线路径上经过的所 述阵列基板已经镀好的图案线条(如图案 2 )边缘的区间, 例如, 可以直接 确定 c-d段、 e-f段为经过图案 2线条边缘的区间;
将所述补线路径上的经过图案线条边缘的区间 (c-d段、 e-f段)与未经 过图案线条边缘的区间 (a-b段、 b-c段、 d-e段、 f-g段、 g-h段)分别设置 成不同的路径区间;
为所述经过图案线条边缘的路径区间设置更慢的镀膜速度, 为其他未经 过图案线条边缘的路径区间设置较快的镀膜速度, 即为 (c-d段、 e-f段)设 置更慢的镀膜速度。
如图 6所示,是根据本发明的修补液晶显示阵列基板断线的方法的补线 后的结构示意图。 从中可以看出, 在每段路径区间上, 根据前述确定的对应 的镀膜速度进行镀膜, 可以使所述补线路径 4上形成连通的镀膜。 其中, 在 c-d段、 e-f段路径区间上采用更慢的镀膜速度, 可以增加镀膜的厚度, 从而 可以避免现在技术中出现镀膜断裂的情形, 从而提高补膜的成功率, 经过上 述的补线过程, 可以使补线路径 4上的镀膜使出现断线的第二图案 3的断线 处重新连通, 而与其经过的其他未出现断线的图案 (如第一图案 2 )之间绝 从上可以看出, 根据本发明的实施例, 通过将补线路径分成多个路径区 间, 且为每个路径区间设置相应的镀膜速度, 可以通过在不同路径区间采用 不同的镀膜速度进行镀膜, 例如, 所述经过图案线条边缘的路径区间设置更 慢的镀膜速度, 以增加此路径区间的镀膜厚度, 可以使所述补线路径上形成 连通的镀膜, 从而提高补线的成功率。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发明 之权利范围, 因此等同变化, 仍属本发明所涵盖的范围。
