有机发光显示面板由于其轻薄、可弯曲的特点，被广泛用于柔性显示装置产品中。空气中的水氧是影响有机发光显示面板使用寿命的主要因素，一种相关技术采用薄膜封装(Thin Film Encapsulation，TFE)技术对包含有机发光器件及其驱动电路的基板进行封装保护，以防止水氧侵入。
本公开的发明人在实现本公开实施例的过程中注意到，有机发光显示面板在生产过程中，边缘处可能已产生裂纹，若不及时检出，直接后果就是导致水氧侵入显示区域，致使有机发光器件失效。为解决该技术问题，本公开实施例提供了一种显示面板及显示装置。在本公开以下各实施例中，连接指电性连接。
如图1所示，本公开一实施例提供的显示面板1，包括：
显示基板10，包括显示区域10P和围绕显示区域10P的非显示区域10Q。该显示基板10包括衬底120，以及位于衬底120的一侧且位于非显示区域10Q的第一邦定部10a、第二邦定部10b、第一连接线路和第二连接线路，其中：第一邦定部10a包括多个第一引脚01，该多个第一引脚01包括第一检测引脚101a和第二检测引脚102a；第二邦定部10b位于第一邦定部10a远离显示区域10P的一侧并与第一邦定部10a连接，第二邦定部10b包括多个第二引脚02，该多个第二引脚02包括第一连接引脚101b和第二连接引脚102b；第一连接线路将第一检测引脚101a和第一连接引脚101b连接，且包括围绕显示区域10P的至少一部分边缘设置的第一裂纹检测线111；第二连接线路将第二检测引脚102a和第二连接引脚102b连接；
集成电路芯片20(Integrated Circuit Chip，IC)，邦定于第一邦定部10a，用于根据主板信号驱动显示基板10显示，及根据第一检测引脚101a和第二检测引脚102a的电信号判断显示基板10的边缘是否存在裂纹；
电路板30，邦定于第二邦定部10b，用于向IC 20传输主板信号，电路板30包括连接线105b，连接线105b将第一连接引脚101b和第二连接引脚102b连接。
显示基板10的显示区域10P用于显示图像，显示基板10的非显示区域10Q用于布置相关电路和相关电子元件，以支持显示区域10P的显示。在本公开实施例中，显示基板10的第一邦定部10a包括多个第一引脚01，该多个第一引脚01与IC 20的多个引脚一一对应邦定，即键合，从而实现第一邦定部10a与IC 20之间电信号的传输。类似的，显示基板10的第二邦定部10b包括多个第二引脚02，该多个第二引脚02与电路板30的多个引脚一一对应邦定，从而实现第二邦定部10b与电路板30之间电信号的传输。第二邦定部10b的一些第二引脚02可以通过内引脚106(Internal pin bonding，ILB)与第一邦定部10a的一些第一引脚01连接，从而实现第二邦定部10b与第一邦定部10a之间电信号的传输。电路板30与显示装置的主板(图中未示出)连接，从而可以通过第二邦定部10b和第一邦定部10a向IC 20传输主板信号。电路板 30例如为柔性印刷电路板(Flexible Printed Circuit，FPC)。IC 20的主要作用是根据主板信号向显示区域10P提供驱动信号、数据信号和时钟信号等，从而驱动显示基板10显示。如图1和图2a所示，在本公开的一些实施例中，IC 20的引脚与第一邦定部10a的第一引脚01之间，以及电路板30的引脚与第二邦定部10b的第二引脚02之间通过导电胶膜001邦定。导电胶膜001例如为异方性导电胶膜(Anisotropic Conductive Film，ACF)。
在本公开实施例中，显示基板10的显示区域10P的具体形状不限，例如呈圆形、椭圆形或者多边形等等。在本公开的一些实施例中，显示区域10P大致呈多边形，例如，大致呈图1所示的矩形。第一邦定部10a与显示区域10P的其中一个边相邻，例如，第一邦定部10a与大致呈矩形的显示区域10P的其中一个长边相邻。第二邦定部10b位于第一邦定部10a的远离显示区域10P的一侧。显示区域大致呈多边形，可以理解为：在忽略显示区域的圆倒角、斜倒角或者工艺误差后，显示区域的形状为多边形。
在本公开的一些实施例中，显示基板10为主动矩阵有机发光二极管(Active Matrix Organic Light-Emitting Diode，AMOLED)显示基板。如图2d所示，AMOLED显示基板的显示区域10P的像素结构包括有机发光器件121、薄膜晶体管器件122和电容器件123，每个有机发光器件121受薄膜晶体管器件122的控制，可以独立且连续的发光。在本公开的另一些实施例中，显示基板也可以为被动矩阵有机发光二极管(Passive Matrix Organic Light-Emitting Diode，PMOLED)显示基板。PMOLED显示基板的显示原理为，以扫描方式点亮显示区域呈阵列排布的有机发光器件，每个有机发光器件在短脉冲下瞬间发光。
在本公开一些实施例中，显示基板10为AMOLED显示基板，其衬底120可以为柔性衬底或者硬质衬底，衬底120的具体材料类型不限。例如，在一些实施例中，衬底120为柔性衬底，衬底的材料包括聚酰亚胺。在另一些实施例中，衬底120为硬质衬底，材料包括玻璃或者树脂等。
如图2a和图2d所示，在本公开的一些实施例中，AMOLED显示基板的结构包括：位于衬底120的一侧且沿远离衬底120的方向依次设置的阻挡层41、缓冲层42、半导体层43、第一绝缘层44、第一栅金属层115a、第二绝缘层45、第二栅金属层115b、第三绝缘层46、数据金属层116、平坦层47、阳极层48、像素界定层49、有机功能层50、阴极层51和封装层117。封装层117曝露出第一邦定部10a的多个第一引脚 01和第二邦定部10b的多个第二引脚02。在本公开的一些实施例中，显示面板为触控显示面板，显示基板还包括位于封装层的远离衬底的一侧的触控结构层。
在本公开实施例中，IC 20除了用于向显示区域10P提供与显示相关的信号外，还用于根据第一检测引脚101a和第二检测引脚102a的电信号，例如电位差，判断显示基板10的边缘是否存在裂纹。如图1所示，第一检测引脚101a、第一连接线路、第一连接引脚101b、连接线105b、第二连接引脚102b、第二连接线路和第二检测引脚102a依次连接形成裂纹检测电路，其中，第一连接线路所包含的第一裂纹检测线111围绕显示区域10P的至少一部分边缘设置。如果显示基板10的边缘存在裂纹，那么，第一裂纹检测线111在裂纹应力的作用下，很有可能也会产生裂纹，甚至断裂。第一裂纹检测线111出现裂纹后阻值会大幅增加，第一裂纹检测线111断裂后会导致裂纹检测电路断路。因此，通过检测第一检测引脚101a和第二检测引脚102a的电信号，可以大致判断出显示基板10的边缘是否存在裂纹。在显示面板的生产阶段，及时将存在裂纹的不良品筛出，可以提高显示装置的产品品质，避免人力资材的大量浪费。
如图1所示，在本公开的一些实施例中，第一连接线路包括围绕显示区域10P的第一部分边缘的第一裂纹检测线111，第二连接线路包括围绕显示区域10P的第二部分边缘的第二裂纹检测线131，其中，显示区域10P的第一部分边缘和第二部分边缘无重合。显示区域10P被裂纹检测线所围绕的边缘的长度越大，即显示区域10P的上述第一部分边缘和第二部分边缘的长度之和越大，IC 20对显示基板10的边缘进行裂纹检测的准确性越高。
如图1所示，第一连接线路包括连接第一裂纹检测线111的一端与第一检测引脚101a的第一引线11a，以及连接第一裂纹检测线111的另一端与第一连接引脚101b的第二引线11b，第二引线11b与第一邦定部10a在衬底120上的正投影无交叠；类似的，第二连接线路包括连接第二裂纹检测线131的一端与第二检测引脚102a的第三引线13a，以及连接第二裂纹检测线131的另一端与第二连接引脚102b的第四引线13b，第四引线13b与第一邦定部10a在衬底120上的正投影无交叠。
由于IC 20需要向显示区域10P提供驱动信号、数据信号和时钟信号等诸多信号，因此，第一邦定部10a的结构设计相对第二邦定部10b更为复杂。此外，为使IC 20与第一邦定部10a可靠连接，在将IC 20与第一邦定部10a邦定时，所需施加的外力也相对较大。本公开的发明人在实现本公开实施例的过程中发现，如果显示面板的裂纹检测电路的一部分走线沿IC邦定部的长度方向经过IC邦定部，那么该部分走线还 需要通过跳线设计避开IC邦定部上的引脚，这使得IC邦定部的结构复杂度和制作难度成倍增加，不但工艺成本较高，易产生工艺不良，而且也加大了因邦定应力导致电路结构被破坏的可能性。
在本公开实施例中，裂纹检测电路除第一检测引脚101a和第二检测引脚102a设置在了第一邦定部10a，其走线结构基本都设置在了第一邦定部10a所在区域之外，作为裂纹检测电路一部分的连接线105b，还设置在了电路板30上，第一检测引脚101a和第二检测引脚102a与其它第一引脚的结构相类似。因此，对比上述相关技术，本公开实施例可以减小第一邦定部10a的结构复杂度和制作难度，从而减少工艺不良发生，降低工艺成本，减小因邦定应力导致电路结构被破坏的可能。
此外，本公开实施例中，裂纹检测电路的走线结构基本都设置在第一邦定部10a所在区域之外，这使得走线设计的自由度也大大增加，走线在衬底120上的投影位置、走线的材料、走线的层位置均可以灵活选择，因此，更有利于优化显示基板的电学性能。
如图1所示，电路板30上的连接线105b与第二邦定部10b在衬底120上的正投影也无交叠，也就是说，电路板30与第二邦定部10b邦定后，连接线105b位于第二邦定部10b所在区域之外，连接线105b基本不受邦定力的影响，这使得电路板30与第二邦定部10b连接的可靠性更高。并且，连接线105b在电路板30上的层位置和材料选择的灵活性也更高。在一些实施例中，连接线105b的材料包括铜。
第一引脚01和第二引脚02的具体结构不限。如图2a和图2b所示，在一些实施例中，第一引脚01包括：位于第一栅金属层115a的第一传输子层01a，以及位于数据金属层116并通过过孔与第一传输子层01a连接的第二传输子层01b，第二引脚02为位于数据金属层116的单层传输部。此外，连接第一邦定部10a和第二邦定部10b的内引脚106也位于数据金属层116。为简化制作工艺，第一引线11a和第三引线13a设置在第一栅金属层115a，与各个第一引脚01的第一传输子层同层制作并连接。
如前所述，由于第二引线11b和第四引线13b设置在第一邦定部10a所在区域之外，因此，第二引线11b和第四引线13b的结构形式可以灵活选择。例如，第二引线11b和第四引线13b位于第一栅金属层115a，或者，第二引线11b和第四引线13b位于第二栅金属层115b，或者，第二引线11b和第四引线13b均包括层叠的两个子层，两个子层分别位于第一栅金属层115a和第二栅金属层115b，等等。在一些实施例中，第二引线11b和第四引线13b位于第二栅金属层115b，第二引线11b通过过孔与第 一连接引脚101b连接，第四引线13b通过过孔与第二连接引脚102b连接。
如图3所示，在本公开的一些实施例中，衬底120为柔性衬底，显示区域10P大致呈多边形，第一邦定部10a与显示区域10P的一个边相邻；显示基板10还包括位于衬底120的一侧且位于显示区域10P与第一邦定部10a之间的折弯部61，折弯部61包括间隔设置且与边大致垂直的多根假线610，多根假线610位于前述的数据金属层116；第一引线11a、第二引线11b、第三引线13a和第四引线13b中的任意一个在衬底上的正投影位于相邻两根假线610在衬底120上的正投影之间。此外，在本公开的其它实施例中，第一引线、第二引线、第三引线和第四引线中的至少一个也可以位于前述多根假线所在的区域之外。
该实施例显示面板1应用于显示装置时，需要凭借折弯部61将第一邦定部10a和第二邦定部10b折向显示基板10的背侧，从而使IC 20和电路板30固定在显示基板10的背侧。间隔设置且与边大致垂直的多根假线610可以提高弯折的柔韧性，使其层结构不易发生断裂。在本公开的一些实施例中，多根假线610位于前述的数据金属层116，数据金属层116的材料可以采用钛铝钛或钼铝钼等，具有较好的延展性，这使得折弯部61的弯折柔韧性更佳。
第一引线11a、第二引线11b、第三引线13a和第四引线13b中的任意一个在衬底120上的正投影位于相邻两根假线610在衬底120上的正投影之间，这样，第一引线11a、第二引线11b、第三引线13a和第四引线13b可以受到假线610的保护，不易因弯折而发生断裂，提高了裂纹检测电路的可靠性。
如图2c和图2d所示，在本公开的一些实施例中，第一裂纹检测线111和第二裂纹检测线131均包括交替连接的多个第一检测段1110和多个第二检测段1111，其中，第一检测段1110位于第二栅金属层115b，第二检测段1111位于数据金属层116，第一检测段1110和第二检测段1111通过过孔连接。
本公开的发明人注意到，显示面板或显示装置在生产和运输过程中，如果走线在同一金属层中连续延伸长度过长，很容易发生静电击穿。在本公开上述实施例中，第一裂纹检测线111和第二裂纹检测线131均包括交替连接且不同层的多个第一检测段1110和多个第二检测段1111，相邻的第一检测段1110和第二检测段1111通过过孔连接，这样，可以有效减少裂纹检测线被静电击穿的可能。
本公开的发明人还注意到，显示面板的角部区域由于其形状特点，更容易因积聚的静电电荷发生尖端放电，导致走线被静电击穿。在本公开的一些实施例中，至少一 个第二检测段1111与显示区域10P的角相邻，这样，可以有效减少、甚至避免裂纹检测线在角部区域被静电击穿。此外，该实施例结构设计，还使得第一裂纹检测线111和第二裂纹检测线131在角部区域的结构对裂纹应力更加敏感，更容易被裂纹应力损伤或破坏，因此，能够进一步提高裂纹检测的灵敏性和准确性。
在图2c和图2d所示的实施例中，第一检测段1110位于第二栅金属层115b，第二检测段1111位于数据金属层116。显示基板10的结构中，第二栅金属层115b两侧的绝缘层总厚度基本相当，将长度占比相对较大的第一检测段1110设置在第二栅金属层115b，这样，第一检测段1110对于任意一侧绝缘层断裂所带来应力的敏感性基本相当，因此，能够更准确的反映裂纹情况，从而更有利于提高裂纹检测的准确性。
如图1所示，在本公开的一些实施例中，第一裂纹检测线111围绕显示区域10P的第一部分边缘并且呈迂绕状，第二裂纹检测线131围绕显示区域10P的第二部分边缘并且呈迂绕状。这样设计可以显著增加裂纹检测线在有限的布线区域内的总长度，在同一位置附近，只要其中任意一段产生裂纹或者断裂，IC 20便可以判断出显示基板10的边缘存在裂纹，因此，检测的灵敏性和准确性进一步提高。
第一裂纹检测线111和第二裂纹检测线131的长度和所采用的迂绕设计形式不限，可以根据显示装置的边框尺寸情况来设计。例如，图1所示的实施例中，为例兼顾显示装置的窄边框效果，第一裂纹检测线111包括两个第一检测段111a和一个第一连接段111b，两个第一检测段111a在衬底120上的正投影间隔设置，第二裂纹检测线131包括两个第二检测段131a和一个第二连接段131b，两个第二检测段131a在衬底120上的正投影间隔设置。
如图4所示，在本公开的另一些实施例中，第一连接线路包括围绕显示区域10P的至少一部分边缘的第一裂纹检测线111，第二连接线路为将第二检测引脚102a和第二连接引脚102b连接的内引脚106。显示区域10P被第一裂纹检测线111所围绕的边缘的长度越大，IC 20对显示基板10的边缘进行裂纹检测的准确性越高。
如图5所示，在本公开的又一些实施例中，第一连接线路包括围绕显示区域10P的第一部分边缘的第一裂纹检测线111，第二连接线路包括围绕显示区域10P的第二部分边缘的第二裂纹检测线131，其中，显示区域10P的第一部分边缘和第二部分边缘部分重合。该实施例进一步增加了显示区域10P被裂纹检测线所围绕的边缘的长度，从而进一步提高了IC 20对显示基板10的边缘进行裂纹检测的准确性。
如图6所示，在本公开的一些实施例中，第一裂纹检测线111的至少一部分呈波 形延伸，例如呈折线波或曲线波形状延伸。第二裂纹检测线131的至少一部分呈波形延伸，例如呈折线波或曲线波形状延伸。采用该设计，也可以增加第一裂纹检测线111和第二裂纹检测线131在各自有限的布线区域内的长度，从而进一步提高IC 20对显示基板10的边缘进行裂纹检测的灵敏性和准确性。
在本公开的一些实施例中，第一裂纹检测线111和第二裂纹检测线131的长度大致相等。这样，通过第一裂纹检测线111的裂纹或断裂检测出显示基板10的边缘存在裂纹的概率，大致等于通过第二裂纹检测线131的裂纹或断裂检测出显示基板10的边缘存在裂纹的概率，并且，也便于第一裂纹检测线111和第二裂纹检测线131的走线设计和制作。其中，第一裂纹检测线111和第二裂纹检测线131的长度大致相等，可以理解为：第一裂纹检测线111和第二裂纹检测线131的长度之差在一定的误差范围内。
如图7所示，在本公开的一些实施例中，第二邦定部10b的多个第二引脚02还包括第一外测试引脚103b和第二外测试引脚104b，第一外测试引脚103b通过一个内引脚106与第一检测引脚101a连接，第二外测试引脚104b通过一个内引脚106与第二检测引脚102a连接。显示基板10在制作过程中，需要对裂纹检测电路是否合格进行测试，第一外测试引脚103b和第二外测试引脚104b用于外接触电压计的探针。通过检测第一外测试引脚103b和第二外测试引脚104b的电压，可以判断IC 20在裂纹检测电路中是否正常工作。
如图8所示，本公开实施例还提供了一种显示装置100，包括前述任一实施例的显示面板1。图8所示的实施例中，显示装置为包含可弯折柔性显示面板的显示装置。在本公开的其它实施例中，显示装置也可以为包含平面显示面板的显示装置，或者为包含曲面显示面板的显示装置。显示装置的具体产品类型不限，例如可以为显示器、电脑、电视机、手机、可穿戴设备、电子纸或者展示屏等等。
如前面的描述，由于在显示面板的生产阶段便可以将边缘存在裂纹的不良品筛出，因此，显示装置的产品品质较高。
至此，已经详细描述了本公开的各实施例。为了避免遮蔽本公开的构思，没有描述本领域所公知的一些细节。本领域技术人员根据上面的描述，完全可以明白如何实施这里公开的技术方案。
虽然已经通过示例对本公开的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本公开的范围。本领域的技术人员应该理解，可在不脱离本公开的范围和精神的情况下，对以上实施例进行修改或者对部分技术特征进行等同替换。本公开的范围由所附权利要求来限定。
