另外，下面结合附图描述的本申请的实施方式是示例性的，仅用于解释本申请的实施方式，而不能理解为对本申请的限制。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
目前，异形切割一般利用高功率密度激光束照射被切割材料(如本申请的显示面板)，使材料很快被加热至汽化温度，蒸发形成孔洞，同时借助与光束同轴的高速气流吹除熔融物质，随着光束对材料的移动，形成切缝。具有切割尺寸精度高、切口无毛刺、切缝不变形、切割速度快且不受加工形状限制等特点，有望在全面屏异形切割领域获得大规模应用，但是相比较而言则会有成本高的不足。然而，异形切割过程中，激光的异形路径更容易产生不需要的冲击。另一方面，异形的显示面板，在切割制作过程中，容易受物理挤压碰撞，产生裂纹风险高，具有裂纹的显示面板显示效果可能会受到影响，影响产品良率。
请参阅图2和图3，本申请实施方式的显示面板10包括基板11、多个子像素12、多条数据线13和裂纹检测线14。基板11包括显示区111和围绕显示区111的周边区112，周边区112包括第一周边区1121和第二周边区1122，第一周边区1121环绕显示区111，第二周边区1122位于第一周边区1121的一侧；多个子像素12位于显示区111；多条数据线13位于显示区111且与多个子像素12电连接；裂纹检测线14位于基板11上，裂纹检测线14围绕显示区111，且沿第一周边区1121和第二周边区1122的边缘线L设置，裂纹检测线14与多条数据线13中的至少一条电连接。
本申请实施方式的显示面板10通过在显示面板10的周边区112的边缘线L设置裂纹检测线14，在周边区112出现裂纹时，裂纹检测线14会断裂，导致裂纹检测线14传输的信号受到影响，从而根据与裂纹检测线14电连接的子像素12是否点亮判断周边区112是否出现裂纹，可准确地检测显示面板10在异形切割时是否损坏，帮助质检员工筛选出显示效果差的显示面板10，保证产品良率。
请参阅图1和图2，本申请实施方式的显示装置100包括显示面板10、和驱动芯片30。显示面板10设置在机壳20上。

机壳20可用于安装显示面板10，或者说，机壳20可作为显示面板10的安装载体。显示装置100包括相背的正面和背面，显示面板10为一个，可设置在正面；显示面板10还可为多个(如2个)，同时设置在正面和背面。本申请实施方式中，显示面板10设置在正面。机壳20还可用于安装显示装置100的供电装置、通信装置等功能模块，机壳20和显示面板10安装在一起后，围成密闭的收容空间以收容供电装置、通信装置等功能模块，以为功能模块提供防尘、防摔、防水等保护。
请参阅图2，驱动芯片30设置在显示面板10上，驱动芯片30可以是集成电路(Integrated Circuit，IC)芯片。驱动芯片30用于控制显示面板10显示图像。
请参阅图2，显示面板10包括基板11、子像素12、数据线13、裂纹检测线14、第一焊盘15、第二焊盘16、第三焊盘17和阻挡裂纹结构18。
显示面板10可以是有机发光二极管(Organic Light-Emitting Diode，OLED)显示面板10。有机发光二极管显示面板10采用有机发光二极管进行显示，可以实现自主发光，使得每个像素点可独立进行发光控制，无需背光灯，即可实现显示功能，具有轻薄、能耗低、亮度高、发光率好等优点。
基板11可以为玻璃基板11等刚性基板11，或者也可以为柔性树脂等柔性基板11。在柔性基板11上集成驱动电路和显示像素，从而可以制成柔性显示面板10。柔性显示面板10的形状可以是矩形、圆形、椭圆形或者其他任意异形形状，在此不做限制。另外，有机发光二极管显示面板10还可以形成具有良好的透光性的透明显示面板10，满足更多的显示需求。
基板11包括显示区111和周边区112。周边区112围绕显示区111。
显示区111为用于显示的区域，显示区111内的多个子像素12形成像素阵列，驱动芯片30通过显示区111的数据线13连接到像素阵列，并用于根据输入信号驱动像素阵列工作，以实现图像的显示。
显示区111可以是矩形、圆形、圆角矩形等，多个子像素12均位于显示区111内，多个子像素12排布而成的像素阵列可以是矩阵、圆阵或其他形状的阵列，可根据显示区111的形状设置，在此不做限制。
显示区111还形成有多条数据线13，即，多条数据线13位于显示区111内。每条数据线13与一个或多个子像素12电连接，以接收输入信号实现对与该条数据线13连接的一个或多个子像素12进行发光控制。
请参阅图2，周边区112包括第一周边区1121、第二周边区1122和第三周边区1123。
第一周边区1121环绕显示区111；第一周边区1121的边界围成具有缺口1124的圆形。
第二周边区1122位于第一周边区1121的一侧，具体为，第二周边区1122位于第一周边区1121远离显示区111的一侧，并与缺口1124连接，第二周边区1122呈矩形，矩形的与缺口1124连接的边的长度等于缺口1124的宽度。
第三周边区1123位于第二周边区1122远离显示区111的一侧。第三周边区1123的 面积大于第二周边区1122的面积，第二周边区1122用于弯折以使得第三周边区1123位于第一周边区1121和显示区111之下，第二周边区1122占用面积较小，有利于显示装置100小型化。
在弯折后，第三周边区1123的面积小于第一周边区1121和显示区111的面积之和，使得弯折后的显示面板10的在水平方向的表面上的投影面积为第一周边区1121和显示区111的面积之和，有利于显示装置100小型化。
第三周边区1123包括走线区1125和焊盘区1126，走线区1125与第二周边区1122连接，走线区1125呈梯形，梯形的上底和第二周边区1122中、与缺口1124连接的边相对的边重合。走线区1125和焊盘区1126连接，焊盘区1126呈矩形，该矩形的长边与走线区1125的下底重合。
请参阅图2，裂纹检测线14位于基板11上，裂纹检测线14围绕显示区111，且沿第一周边区1121和第二周边区1122的边缘线L设置。可以理解，在显示面板10进行异形切割时，会沿着预设的切割线进行切割，切割完成后的显示面板10的边缘线L即为该切割线，若切割处出现损坏，就会导致沿边缘线L设置的裂纹检测线14断裂。根据切割线的分布，当第三周边区1123的边缘也存在预设的切割线时，裂纹检测线14还可设置在第三周边区1123的边缘线L，从而保证异形切割的所有部分均能进行裂纹检测，提高检测准确性。
裂纹检测线14包括第一走线段141、第二走线段142和第三走线段143。第一走线段141和第二走线段142相对显示区111对称设置。第三走线段143位于第三周边区1123，并位于多个第二焊盘16和显示区111之间(即走线区1125)，第三走线段143连接第一走线段141和第二走线段142的两个端点。
裂纹检测线14的两个端点分别和两条数据线13电连接，具体地，该两条数据线13分别为第一数据线131和第二数据线132，其中，第一走线段141中未与第三走线段143连接的端点电连接第一数据线131，第二走线段142中未与第三走线段143连接的端点电连接第二数据线132。
可以理解，裂纹检测线14完好时，将检测信号输入裂纹检测线14时的显示区111的显示内容和裂纹检测线14断裂后，将检测信号输入裂纹检测线14时的显示区111的显示内容显然是不同的，后续质检员工在检测时，只需向裂纹检测线14输入测试信号，根据显示内容的不同，即可快速而准确地确定显示面板10是否出现裂纹。
例如，裂纹检测线14与像素阵列的某一行或者某一列的多个子像素12连接，每个子像素12可以包括红色子像素，绿色子像素和蓝色子像素。红色子像素可以发出红光，绿色子像素可以发出绿光，蓝色子像素可以发出蓝光，通过控制红色子像素、绿色子像素和蓝色子像素的亮度可以使得相应的子像素12发出的光线混合形成不同颜色的可见光，进而使得子像素12可以显示相应的色彩。或者裂纹检测线14单独控制红色子像素、绿色子像素或蓝色子像素，通过判断红色子像素、绿色子像素或蓝色子像素是否点亮进而判断裂纹检测线14是否出现裂纹。
而第一走线段141和第二走线段142分别连接两条不同的数据线13，在第一走线段141和第二走线段142均未损坏时，与第一数据线131连接的子像素12(如图3中第三列)和与第二数据线132连接的子像素12(如图3中第六列)均被点亮，在第一走线段141 损坏时，与第一数据线131连接的子像素12(如图4中第三列)显示预定颜色(如绿色)以指示显示面板10中与第一走线段141对应的区域的损坏情况，在第二走线段142损坏后，与第二数据线132连接的子像素12(如图5中第六列)显示预定颜色(如绿色)以指示显示面板10中与第二走线段142对应的区域的损坏情况。从而在判断显示面板10损坏情况时，准确的判断出现裂纹的区域。
请参阅图2，第一焊盘15位于第三周边区1123(具体为焊盘区1126)。第一焊盘15包括多个，多个第一焊盘15中，存在一个或多个用于实现裂纹检测第一检测焊盘151，第一检测焊盘151与裂纹检测线14电连接。
第一检测焊盘151被配置为可接收测试信号，然后控制输入信号通过裂纹检测线14传递给至少一条数据线13，本实施方式中，第一焊盘15接收测试信号后，测试信号通过第一焊盘15传输给裂纹检测线14，然后再传输给裂纹检测线14连接的第一数据线131和第二数据线132。
第二焊盘16位于第三周边区1123(具体为焊盘区1126)并被配置为与驱动芯片30电连接，第二焊盘16包括多个，多个第二焊盘16中，存在一个或多个用于实现裂纹检测第二检测焊盘161，第二检测焊盘161与裂纹检测线14电连接。
驱动芯片30接收测试信号，然后通过第二检测焊盘161传输给裂纹检测线14，然后再传输给裂纹检测线14连接的第一数据线131和第二数据线132，从而实现对第一数据线131和第二数据线132对应的子像素12的显示控制。
驱动芯片30设置在第三周边区1123并覆盖多个第二焊盘16，驱动芯片30还可以接收输入信号，通过第二焊盘16传输给所有数据线13，从而实现显示区111的显示内容的控制。
第三焊盘17位于第三周边区1123(具体为焊盘区1126中，多个第二焊盘16远离显示区111的一侧)，第三焊盘17为多个，多个第三焊盘17中，存在一个或多个用于检测驱动芯片30接收输入信号后是否能够输出准确的输出信号的第三检测焊盘171，第三检测焊盘171与裂纹检测线14电连接。驱动芯片30接收到输入信号后，通过第二检测焊盘161传输给第三走线段143，从而传递给第三检测焊盘171，显示装置100(图1示)还包括电路板40，第三焊盘17与电路板40电连接，电路板40覆盖多个第三焊盘，通过电路板40可获取第三焊盘17(即，第三检测焊盘171)输出的输出信号，通过比对从第三检测焊盘171获取的输出信号与预定信号，根据两者的差异即可判断驱动芯片30是否能够输出准确的输出信号。
请参阅图2，阻挡裂纹结构18位于周边区112的边缘，具体地，阻挡裂纹结构18可沿着周边区112的边缘线L设置，且位于裂纹检测线14远离显示区111的一侧，以阻挡显示面板10在异形切割工序中的裂纹。
例如阻挡裂纹结构18沿着第一周边区1121的边缘线L和第二周边区1122的边缘线L设置；或者，阻挡裂纹结构18沿着第一周边区1121的边缘线L、第二周边区1122的边缘线L和第三周边区1123的边缘线L设置等，在此不做限制，可根据需要进行裂纹检测的区域进行设置即可。本实施方式中，阻挡裂纹结构18沿第一周边区1121的边缘线L、第二周边区1122的边缘线L和第三周边区1123的边缘线L设置，且包围裂纹检测线14。
阻挡裂纹结构18设置在基板11上，用于在显示面板10被切割以成型时，抵消掉一 部分异形切割产生的应力，阻挡裂纹结构18沿周边区112的边缘线L设置，从而针对性的抵消异形切割时边缘线L附近所受的应力，无需在整个基板11均设置阻挡裂纹结构18即可防止显示面板10在异形切割过程中损坏。
阻挡裂纹结构18设置在裂纹检测线14远离显示区111的边缘的一侧，从而使得裂纹检测线14检测的是在阻挡裂纹结构18抵消应力后显示面板10是否损坏，准确性更高。
阻挡裂纹结构18为挡墙的形式(即，阻挡裂纹结构18包括挡墙181)，挡墙181自基板11向远离基板11方向延伸而成，从基板11上凸出。
挡墙181可以是一个或多个，挡墙181为一个时，挡墙181的形状与边缘线L围成的形状(即，第一周边区1121、第二周边区1122和第三周边区1123组合而成的形状)基本相同，挡墙181沿着边缘线L设置，挡墙181和边缘线L间隔预定距离。如此，挡墙181可更好的抵消异形切割时产生的应力，防止显示面板10出现裂纹。
请参阅图6，挡墙181还可包括多个子挡墙182，多个子挡墙182的形状均与边缘线L围成的形状基本相同，以形成多层结构，相邻的两层子挡墙182之间间隔预定距离。相较于单层挡墙181仅削弱一次异形切割产生的应力而言，多层子挡墙182(如图6所示的3层子挡墙182)依次排布且相隔预定距离，可将异形切割产生的应力多次削弱，从而更好的防止显示面板10出现裂纹。
挡墙181为多个时，多个挡墙181沿边缘线L依次设置，从而抵消边缘线L处在异形切割时产生的应力，防止显示面板10出现裂纹。且相较于与边缘线L围成的形状基本相同的单个挡墙181形成的环形无缝结构相比，多个挡墙181之间存在缝隙，占用显示面板10的空间较小，且相邻挡墙181之间的缝隙可用于布线。
本申请实施方式的显示面板10和显示装置100通过在显示面板10的周边区112的边缘线L设置裂纹检测线14，在周边区112出现裂纹时，裂纹检测线14会断裂，导致裂纹检测线14传输的信号受到影响，从而根据与裂纹检测线14连接的子像素12是否点亮判断是否出现裂纹，可准确地检测显示面板10在异形切割时是否损坏，帮助质检员工筛选出显示效果差的显示面板10，保证产品良率。且阻挡裂纹结构18占用空间小，并可以起到防止显示面板10因异形切割而发生损坏的作用。另外，机壳20能够对组装后的显示面板10起到一定的保护作用。
