图 5 是本公开的第二实施例的一种彩膜基板和阵列基板对盒后在阵列 基板的外围电路区域的数据线和彩膜基板上公共电极的图形。 具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例仅仅是本公开一部分实施例， 而 不是全部的实施例。基于本公开中的实施例， 本领域普通技术人员在没有作 出创造性劳动前提下所获得的所有其他实施例， 都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领 域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权 利要求书中使用的 "第一"、 "第二" 以及类似的词语并不表示任何顺序、 数 量或者重要性， 而只是用来区分不同的组成部分。 同样， "一个" 或者 "一" 等类似词语也不表示数量限制， 而是表示存在至少一个。 "连接" 或者 "相 连"等类似的词语并非限定于物理的或者机械的连接， 而是可以包括电性的 连接， 不管是直接的还是间接的。 "上"、 "下"、 "左"、 "右" 等仅用于表示 相对位置关系， 当被描述对象的绝对位置改变后， 则该相对位置关系也相应 地改变。
为了在外围电路区域的数据线断路或该数据线与公共电极短路时能够 进行修复， 本实施例中， 将彩膜基板上的与对应的阵列基板（彩膜基板和阵 列基板对盒形成液晶盒， 即该阵列基板为将与彩膜基板对盒的阵列基板）上 夕卜围电路区域中的数据线相对应的该部分的公共电极设计为图形相似，例如 可以设计为独立的若干段条状电极图形，即公共电极与对应的阵列基板像素 电极区域相对应的部分可仍保持为块状，而公共电极与对应的阵列基板外围 电路区域相对应的部分则与与外围电路区域的数据线图形相似，且具有独立 的若干段条状电极图形。 如图 2所示， 彩膜基板上与阵列基板外围电路区域 的一条数据线 1相对应的公共电极部分包括多条分割的条状电极 3 , 每个条 状电极 3均沿数据线 1长度方向延伸， 且与数据线 1上下交叠， 即数据线 1 和条状电极 3在彩膜基板上的投影部分重叠。由于阵列基板和彩膜基板间隔 有一定距离， 阵列基板上数据线 1与彩膜基板上的条状电极 3不会接触。 在 图 2中示例性地显示了三条数据线 1。 对于每条数据线 1 , 与其交叠的多条 条状电极 3中相邻两条条状电极 3通过与该条数据线 1基本不交叠的至少一 个旁路电极 4连接，例如通过在该条数据线 1的两侧分别设置的两个旁路电 极 4连接， 如图 2所示。 彩膜基板上其它区域中的公共电极的图形可以为现 有设计中的块状。靠近像素电极区域的公共电极的条状电极 3可与像素电极 区域的公共电极一体形成， 其它条状电极 3通过旁路电极 4相互连接， 从而 彩膜基板上的公共电极整体电性连接。
为了方便在修复线路时切割旁路电极 4的过程中不会切割到数据线 1 , 旁路电极 4优选和数据线 1完全不交叠。
如图 3所示，采用本实施例的彩膜基板上的条状电极 3修复外围电路区 域中的数据线线路的原理如下。
对于数据线断路的情况， 例如如图 3所示， 数据线 1在 D处断裂， 则 在断裂处 D两端的 E和 F,利用激光焊接将与该数据线 1断裂处对应的条状 电极 3和数据线 1焊接起来， 使该断裂的数据线 1通过条状电极 3连通。 同 时为了避免数据线 1和公共电极接触，将该段条状电极 3与其他公共电极部 分分开，例如通过激光将连接该段条状电极 3与相邻的两条条状电极 3的旁 路电极 4切断， 即图 3中 B和 C处的旁路电极 4切断， 从而完成数据线断 路的修复。
对于例如由于污染物引起的数据线与公共电极短路的情况， 例如如图 3 所示， 数据线 1在 D处短路， 则只需将 B和 C处的旁路电极 4切断， 从而 避免数据线 1与公共电极接触。
每条条状电极 3的图形和与之交叠的数据线 1的图形在彩膜基板上的投 影可以完全重叠，即条状电极 3的图形的宽度可以等于数据线 1的图形的宽 度。 在这种情况下， 若数据线 1和条状电极 3之间存在异物， 则可能导致两 者同时断裂， 从而无法用条状电极 3修复数据线 1。 因此， 进一步地， 每条 条状电极 3的图形的宽度可大于与之交叠的数据线 1的图形的宽度，以至于 在数据线 1和条状电极 3之间存在异物时， 两者不同时断裂。 如图 4所示， 每条条状电极 3的图形的宽度 W1可为数据线 1宽度 W的 5/4 ~ 7/5倍。 为 了方便焊接， 且在制作条状电极 3时， 避免相邻两条数据线 1对应的条状电 极 3相互重叠或接触。 优选地， 条状电极 3的图形的宽度 W1为数据线 1宽 度 W的 4/3倍。 更近一步地， 为了方便焊接， 条状电极 3的宽度 W1大于数 据线 1的宽度 W,且每条条状电极的图形和与该之交叠的数据线图形在沿数 据线 1长度方向上对中， 即两者的中心线在彩膜基板上的投影完全重合。
条状电极 3的长度 L1例如为数据线 1宽度 W的 18 ~ 25倍， 例如 20 倍， 其长度 L1可以根据不同型号产品的阵列基板的数据线设计而定。 对于 每条数据线 1 , 与其交叠的多条条状电极 3中相邻两条条状电极 3之间的间 距 L2例如为数据线 1宽度 W的 2 ~ 3倍。 若相邻两条条状电极 3之间的间 距太宽， 则在相邻两条条状电极 3间隔处的数据线 1断裂时， 4艮难修复数据 线 1。 优选地， 相邻两条条状电极 3之间的间距 L2为数据线 1宽度 W的 2 倍。
进一步地， 旁路电极 4的宽度 W2例如为数据线 1宽度 W的 1/8 ~ 1/5。 旁路电极 4与数据线 1之间的最大距离 W3例如为数据线 1宽度 W的 1/5 ~ 1/3。 在制作旁路电极 4时， 优选避免旁路电极 4与其对应的数据线 1完全 交叠， 从而不便于后续切割， 而且优选避免旁路电极 4与相邻的数据线 1交 叠， 及与相邻的数据线 1连接的旁路电极 4重叠或接触。 基于以上的因此， 优选地， 旁路电极 4的宽度 W2为数据线 1宽度 W的 1/6, 旁路电极 4与数 据线 1之间的最大距离 W3为数据线 1宽度 W的 1/4。
进一步地， 为了使两条条状电极 3连接更加稳定， 对于每条数据线， 与 其交叠的多条条状电极中相邻两条条状电极通过两个分别位于条状电极 3 宽度方向上两侧的旁路电极 4连接。
进一步地， 对于阵列基板上相邻数据线 1 , 与各数据线 1相应交叠段对 应的多条条状电极 3在沿数据线 1宽度方向上对齐。如图 2中虚线条对齐线 所示， 与各数据线 1相应交叠段对应的多条条状电极 3不但形状相同、 长度 相等， 而且在沿数据线 1宽度方向上对齐。 优选地， 所有条状电极 3的形状 相同、 长度相等。 这样可以在制作条状电极 3的掩膜工艺中方便掩膜板的图 形设计。
进一步地，为了避免修复完成后由于切割导致某条数据线 1上的条状电 极 3和其相邻的条状电极 3断开，使得与该条数据线 1交叠且靠近面板边缘 的条状电极 3无法连接到公共电极， 如图 5所示， 彩膜基板还包括多个连接 电极 6。 连接电极 6连接与相邻两条数据线 1分别对应的且沿数据线 1宽度 方向上对齐的两个条状电极 3 , 其位置不与旁路电极 4重叠。 为了在制作条 状电极 3的掩膜工艺中方便掩膜板的图形设计， 优选地， 连接电极 6连接两 个条状电极 3的连接点分别位于各条状电极 3的中间位置。连接电极 6可以 为条状， 其宽度可以为数据线的 1 ~ 2倍。
对于图 5中的具有连接电极 6的彩膜基板，在修复线路时只需再切断与 用作修复线路用的条状电极 3相应的连接电极 6即可。
本公开还提供了一种显示装置， 包括阵列基板， 以及与所述阵列基板对 盒的上述彩膜基板。
由于制作公共电极的材料通常是透明材料， 所以条状电极 3、 旁路电极 4和连接电极 6可以都是透明的。 因此如图 2所示， 为了在修复线路的过程 中易于定位上述透明的电极的位置。 在阵列基板外围电路区域中的数据线 1 上在与条状电极 3之间的间隔相对应的位置设置有第一标记柱 5。 第一标记 柱 5和数据线 1在同一次掩膜工艺中形成，且可以用与数据线 1相同材料形 成， 例如用不透明金属形成。 在修复过程中通过查找第一标记柱 5的位置来 定位一段条状电极 3及与该条状电极 3连接的旁路电极 4。 如图 4所示， 第 一标记柱 5的宽度 W4可为数据线 1宽度 W的 1/6~1/4, 如 1/5 , 第一标记 柱 5的长度 L4可为数据线 1宽度 W的 1/8 ~ 1/5 , 如 1/6。
为了便于识别上述连接电极 6的位置，如图 5所示，相邻两个第一标记 柱 5的之间还可设有第二标记柱 7, 以便于定位连接电极 6的位置。 第二标 记柱 7和第一标记柱 5的大小形状均可相同。
在制作阵列基板和彩膜基板各自的电极图形的过程中， 对第一标记柱 5、 第二标记柱 7的位置、 条状电极 3、 旁路电极 4和连接电极 6的位置通 过掩膜工艺事先确定， 且保证对盒后能够形成如图 2或 4的电极图形。
所述显示装置可以为： 液晶面板、 电子纸、 OLED面板、 手机、 平板电 脑、 电视机、 显示器、 笔记本电脑、 数码相框、 导航仪等任何具有显示功能 的产品或部件。
以上实施方式仅用于说明本公开， 而并非对本公开的限制，有关技术领 域的普通技术人员， 在不脱离本公开的精神和范围的情况下， 还可以做出各 种变化和变型， 因此所有等同的技术方案也属于本公开的范畴， 本公开的专 利保护范围应由权利要求限定。
