本发明的其它特征和优点将在随后的说明书中阐述， 并旦， 部分地从说明书 中变得显而易见， 或者通过实施本发明而了解。 本发明的目的和其他优点可通过 在说明书、 权利要求书以及附图中所特别指出的结构来实现和获得。
附图用来提供对本发明的进一步理解， 并旦构成说明书的一部分， 与本发明 的实施例共同 于解释本发明， 并不构成对本发明的限制。 在^图中：
图 1显示了现有技术中断线修复线路设计的布局图；
图 2显示了根据本发明的一个实施倒的断线修复线路设计的布局图； 图 3显示了现有技术中的源极驱动电路 Source IC侧的输入输出的布局图- 图 4显示了配合本发明的断线修复线路设计的源极驱动电路 Source IC侧的 输入输出的布局图； 以及
图 5是根据本发明的一个实施例的显示面板的断线修复方法的流程图。 具体实施方式
以下将结合^图及实施例来详细说明本发明的实施方式， 借此对本发明如何 应用技术手段来解决技术问题， 并达成技术效果的实现过程能充分理解并据以实 施。 需要说明的是， 只要不钩成 突， 本发明中的各个实施例以及各实施例中的 各个特征可以相互结合， 所形成的技术方案均在本发明的保护范围之内。
如图〗所示为传统的阵列基板外 电路布局，其中展示了 4条修复断线（RP1 , RP2, ΚΡ3 , RP4 ) 的修复线设计。 如图 1所示的布局， 其最多能修复 4条断线， 分别是左边区域两条， 右边区域两条。 该设计的修复方法中包括以下一些歩骤： 如果显示阵列基板的左边区域的第 η条数据线发生了断路缺陷时， 将该条数 据线路的数据输出端和数据输入端分别与同一条修复线路的两端进行瑢接。 如果 有一端的熔接操诈失败， 那么修复操作就无法完成。 此外， 由于修复后的数据线 驱动信号要通过熔接点和整条修复线路才能输送到数据线输出端， 信号的衰减较 大， 因此通常还需要在印制电路板 PCB 106上增加 ΟΡ放大电路 107。 对应于该 修复电路的源极驱动电路如图 3所示。
明显看出上述修复断线的方法操作步骤涉及到两次的熔接操作， 这是比较费 时旦不可靠的。 此外， 修复线路的设†也比较复杂。 因此， 为了简化修复线路和 修复方法， 提高修复成功率， 本发明提供一种如图 2所示的断线修复电路设计。 其中显示的是修复垂直断线的电路设计， 但本发明不限于此， 采用本发明的思想 可修复阵列基板上的任何线路。
在图 2中， 其示出了显示面板 101、 阵列基板 102、 X向的覆晶薄膜 COF模 组 103、 Y-向的覆晶薄膜 COF模组 104、 源极驱动电路 ( Source IC ) 105等。 阵 列基板上包括： 栅线 （Gate Lme ) 、 数据线 （Data Life ) 。 其中， 櫥线并行地布 置在基底上用于向显示面板传输扫描信号。 数据线与栅线不同层地布置在基底 上， 但在走向上与栅线垂直， 其 ¾于向显示面板传输源极驱动信号。
此外， 还在面板***布置了两条或两条以上的修复线路 （RP i， RP2 , RP3， RP4 ) , 其设在基底上并包括第一组端子和第二组端子， 其中第一组端子空置， 以便在检测到数据线中某条数据线出现断点时将修复线路之一的第一组端子与 发生断路的数据线的输出端短接。 修复线路的第二组端子与源极驱动电路的输出 端连接， 以在源极驱动电路得到断路修复控制信号时， 向第二组端子输出与存在 断点的数据线的输入端相同的驱动信号， 使得修复线路的整体将断点位置的线路 连通。
根据本发明的一个实施例， 修复线路 （RPL RP2 ? RP3 ? RP4 ) 与数据线可 以设置在基底的同 ·层上， 以便干进行第一组空置端子与数据线输出端的短接。 如果不在同一层， 剣需要在布置数据线的那一层设置能够到达设有修复线路的那 层的过孔。 本发明不限于此， 本领域的技术人员可以想到任何方便将修复线路 的空置端子与数据线输出端进行短接的电路布局。
优选地是， 修复线路 （RP1 , RP2, RP3, RP4) 的第一组端子可设在基底的 下部、 靠近数据线输出端的位置， 修复线路的第二组端子设在基底的上部、 靠近 源极驱动电路的位置。 修复线路优选成对地对称布置在基板外周， 设在基板左侧 的修复线路的第二组端子与对应设在左侧的源极驱动电路的输出端连接， 设在基 板右侧的修复线路的第二组端子与对应设在右侧的源极驱动电路的输出端连接。
更具体地说， 如图 2所示， 每条修复线路可设置为均通过了 Y向的覆晶薄膜 COF模组。 虽然， 这里显示的是 4条修复线路， 其对称地布设在面板两侧并沿伸 到底部中央位置停止， 形成近 ί以的 "L"状， 但本发明不限于此， 修复线路的条 数可以根据实际需要为更多如 6条， 或者更少如两条。
很明显， 在图 2中， 省去了数据线输入端的修复线路设计， 修复信号直接从 数据线的焊盘区的管胸沿面板***传递到数据线输出端， 当第 η条数据线发生断 路时， 只需将第 II条数据线的输出端与修复线路的一端， 具体说是第一端熔接或 以其它本领域技术人员可知的任何方式短接。
图 4显示了配合本发明的断线修复线路设计的源极驱动电路 Source IC侧的 输入输出的布局图。 该图中显示的源极驱动电路除了其他部件之外还包括灰阶电 压 （Gamma电压） 输入端、 驱动电压输出端 （数据】， 数据 2, ……数据 数 据 irH 等） 、 修复控制输入端以及修复输出端 （例如分别对应于修复线 RP1 和 RP2的修复输出 3和修复输出 4) 。 此外还包括 Mini LVDS/TTL输入端。
灰阶电压输入端布置于源极驱动电路一侧， ^于接收灰阶电压输入信号。 驱 动电压输出端布置于源极驱动电路另一侧， ^于输出适于驱动液晶显示面板的源 极驱动电压信号。
修复控制输入端用于向源极驱动电路 Source IC输入修复控制信号。 修复控 制信号中指示了数据线中出现断点的位置信息和一端已短接的修复线路的编号。 该信号是在断线修复后写进存储器的。 Source IC 通过修复控制信号提供的断线 坐标来控制修复输出端的输出。
修复输出端与修复线路的第二组端子连接， 并基于上面得到的修复控刺信号 中的位置信息和修复线路的编号向对应的修复线路的第二组端子输出与出现断 点的数据线的输入端相同的驱动信号。
如图 5所示， 提供了一种液晶显示器的数据线断线故障的修复方法， 其包括 以下■步骤：
S50 检测并确定出现断点的数据线，
5502、 将修复线路的第一组端子中的一条或多条与出现断点的数据线的输出 端短接；
5503、 在模组编程阶段， 将出现断点的数据线的位置信息和巳短接的修复线 路的编号通过修复控制输入端输入到源极驱动电路中；
5504、 源极驱动电路在向数据线输出驱动电压信号^, 向对应编号的修复线 路的第二组端子输出与出现断点的数据线的输入端相同的驱动信号。
虽然本发明所揭露的实施方式如上， 但所述的内容只是为了便于理解本发明 而采用的实施方式， 并非用以限定本发明。 任何本发明所属技术领域内的技术人 员， 在不脱离本发明所揭露的精神和范 的前提下， 可以在实施的形式上及细节 上诈任何的修改与变化， 但本发明的专利保护范围， 仍须以所附的权利要求书所 界定的范围为准。
