具体实施方式
为了使本技术领域的人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
参图1所示为现有技术中显示面板检测系统的结构示意图。该显示面板包括基板(未图示)以及位于基板上的若干信号线。
以下以大尺寸TFT-LCD为例对本发明进行说明，下述的第一电极和第二电 极分别为栅极和源漏极，在其他实施方式中第一电极和第二电极并不限于栅极和源漏极。
该显示面板检测系统具体包括：
位于显示区域内的电极信号线，电极信号线包括垂直交叉分布的第一电极信号线11’和第二电极信号线21’；其中，第一电极信号线11’为栅极信号线，第二电极信号线21’为源极或漏极信号线。
与电极信号线相连且向外扇出排列的向外扇出线路，包括与第一电极信号线11’相连且向外扇出排列的第一向外扇出线路12’、以及与第二电极信号线21’相连且向外扇出排列的第二向外扇出线路22’；
与向外扇出线路相连的电极信号输入端，包括与第一向外扇出线路12’相连的第一电极信号输入端13’、以及与第二向外扇出线路22’相连的第二电极信号输入端23’；
信号发射器41’及信号接收器42’，信号发射器位于第一电极信号线11’或第二电极信号线21’的始端并发射信号，信号接收器42’位于第一电极信号线11’或第二电极信号线21’的末端并接收信号。
图2a所示为信号线中不存在断路或短路现象时的正常信号波形示意图，而图2b所示为信号线中存在断路或短路现象时的断路或短路信号波形示意图，因此，通过信号发射器41’及信号接收器42’可以检测出两者之间是否存在断路或短路现象。
由图1可以看出，当信号发射器41’及信号接收器42’移动沿图中指示方向移动时，可以检测出显示区域内第一电极信号线11’上的A’处的断路或短路现象，但显示区域外第一向外扇出线路12’上的B’处的断路或短路现象无法检测出。向外扇出线路上的断路或短路会导致漏放至Mod形成水平淡线，影 响产品良率。
本发明中的一种显示面板检测系统，显示面板包括基板、以及位于基板上的若干信号线，显示面板检测系统具体包括：
位于显示区域内的电极信号线；
与电极信号线相连且向外扇出排列的向外扇出线路；
与向外扇出线路相连的电极信号输入端；
与电极信号输入端相连的测试接垫；
信号发射器及信号接收器，信号发射器从电极信号线的始端发射信号，信号接收器从电极信号线的末端或者测试接垫的末端接收信号。
本发明中定义的“始端”和“末端”以向外扇出线路为参照物，电极信号线和测试接垫上靠近向外扇出线路的端部为始端，远离向外扇出线路的端部为末端。
参图3所示，本发明一具体实施方式中显示面板检测系统具体包括：
位于显示区域内的电极信号线，电极信号线包括垂直交叉分布的第一电极信号线11和第二电极信号线21。在本实施方式中，第一电极信号线11为栅极信号线，第二电极信号线21为源极或漏极信号线；
与电极信号线相连且向外扇出排列的向外扇出线路，包括与第一电极信号线11相连且向外扇出排列的第一向外扇出线路12、以及与第二电极信号线21相连且向外扇出排列的第二向外扇出线路22；
与向外扇出线路相连的电极信号输入端，包括与第一向外扇出线路12相连的第一电极信号输入端13、以及与第二向外扇出线路22相连的第二电极信号输入端23；
与第一电极信号输入端13相连的第一测试接垫31，其中，第一测试接垫 31通过第一连接线32分别与第一信号输入端13相连；
信号发射器41及信号接收器42，信号发射器位于第一电极信号线11的始端并发射信号，信号接收器42位于第一电极信号线11的末端并或第一测试接垫31的末端并接收信号。
进一步地，在其他实施方式中第二电极信号输入端23也可以通过第二连接线连接有第二测试接垫(未图示)，信号发射器和信号接收器分别位于第二电极信号线的始端、第二电极信号或第二测试接垫的末端。其原理与上述实施方式完全相同，本发明中不再进行赘述。
参图3所示，本实施方式中的电极信号线为双向驱动的信号线，信号线通过两个连接线321、322分别与第一测试接垫311、312相连，且两个连接线321、322之间的距离d不小于7μm。且第一测试接垫311、312的长度a不小于300μm，宽度b不小于30μm，相邻第一测试接垫的距离c不小于60μm。值得说明的是，上述设计数据也适用于第二测试接垫。本实施方式中信号发射器41为OST机台信号发射器，信号接收器42为OST机台信号接收器。OST机台也称断路或短路检验装置(Open/Short Test)，该装置用于检测信号发射器41及信号接收器42之间的待检测线路是否存在断路或短路现象，其检测原理是：基板的两端设给电侧(相当于本发明中的信号发射器41)和受电侧(相当于本发明中的信号接收器42)，通过对给电侧向基板一端施加交流电压，通过基板线路对交流信号的传送，在受电端检出信号，并通过对受电端接收的信号进行放大处理和判断，来检出断路或短路缺陷。当信号接收器接收到的信号微弱甚至没有时，判定为断路现象；当信号接收器接收到的衰减至1/2左右(信号分流)时，则判定为短路现象。
可以理解的是，在其他实施方式中也可以为其他信号发射器和信号接收器。
信号发射器41与电极信号线的始端电性连接且沿着电极信号线的始端运动，信号接收器42与该电极信号线的末端或测试接垫的末端电性连接且沿着该电极信号线的末端或测试接垫的末端运动。
当信号接收器在电极信号线的末端接收到的信号为断路或短路信号时，说明对应的电极信号线上(例如A处)存在断路或短路现象，而当信号接收器在测试接垫的末端接收到的信号为断路或短路信号时，说明对应的向外扇出线路上(例如B处)存在断路或短路现象。
本发明中的一种显示面板检测系统的检测方法包括为：
S1、信号发射器从电极信号线的始端发射信号，信号接收器从电极信号线的末端或测试接垫的末端接收信号；
S2、根据信号接收器所接收的信号为正常信号、断路信号或断路信号，判断电极信号线及向外扇出线路是否存在断路或短路现象。
若信号接收器从电极信号线的末端检测到断路信号，则判定电极信号线上存在断路现象，若信号接收器从电极信号线的末端检测到短路信号，则判定电极信号线上存在短路现象；
若信号接收器从测试接垫的末端检测到断路信号，则判定向外扇出线路上存在断路现象，若信号接收器从测试接垫的末端检测到短路信号，则判定向外扇出线路上存在短路现象。
如本实施方式中的检测方法包括为：
S1、信号发射器从第一电极信号线或第二电极信号线的始端，信号接收器从第一电极信号线或第二电极信号线的末端、第一测试接垫或第二测试接垫的末端接收信号；
S2、根据信号接收器所接收的信号为正常信号、断路信号或断路信号，判 断第一电极信号线或第二电极信号线及第一向外扇出线路或第二向外扇出线路是否存在断路或短路现象。
在其他实施方式中，信号发射器也可以从第一电极线或第一测试接垫的末端发射信号，而从第一电极信号线的始端接收信号，同样可以检出第一向外扇出线路及第一电极信号线上是否存在断路或短路现象。
同样地，信号发射器也可以从第二电极线的始端发射信号，而从第二电极信号线或第二测试接垫的末端接收信号，同样可以检出第二向外扇出线路及第二电极信号线上是否存在断路或短路现象。
为实现对向外扇出线路上故障状态的检测，本发明需在原有检测线路的外围对应设置相匹配的扇出的连接线(比如第一连接线32)和检测接垫(比如第一检测接垫31)，连接线和检测接垫的设置可以与栅极电极线或源漏电极线在同一制作工序中完成。此外，增加的连接线和检测接垫均位于最终产品的基板外围，并在完成检测后将被整体切除，不会造成液晶面板非显示区宽度的增加或产品制作工序的增加，即不会影响最终产品和生产工序。
有上述技术方案可以看出，本发明能够检出显示区域内电极线以及显示区域外向外扇出线路上的断路或短路现象，改善了向外扇出线路断路或短路不可检出的现况，降低了Mod水平淡线比例，提升了产品良率。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
