非显示区120设置有多个导电焊垫121及多个静电释放体122，本实施例中导电焊垫121可以为测试焊垫，其中导电焊垫121和显示区110中的信号引线111不直接连接。多个静电释放体122的一端通过相应的信号引线111连接显示区110，多个静电释放体122和相应的导电焊垫 121至少部分交叠且连接。
结合图2及图3，图2为本申请图1中A-A’区的截面示意图，图3为本申请图1中B-B’区的截面示意图。其中，图2为沿着图1中平行于导电焊垫121长边方向的截面示意图，图3为沿着图1中平行于导电焊垫121短边方向的截面示意图。如图2和3，本申请中静电释放体122设置于显示面板100的衬底基板101和导电焊垫121之间，且静电释放体122和导电焊垫121部分交叠。
可选地，静电释放体122进一步包括本体1221以及包覆所述本体1221的第一绝缘层1222，其中，第一绝缘层1222和导电焊垫121部分交叠，且第一绝缘层1222不和导电焊垫121交叠的部分设有第一过孔1223，如图2，信号引线200通过该第一过孔1223和静电释放体本体1221电连接。
可选地，静电释放体122本体1221的材料可选用半导体材料，例如非晶硅或者多晶硅，此处不做具体限定。采用的半导体材料作为静电释放体其具有好的电荷承载能力，对静电放电有更好的接纳能力，且能接收并承载更多的静电放电。
可以理解的是，在导电焊垫121和显示面板100的衬底基板101之间设置该静电释放体122，有利于将显示面板中信号引线(本实施例中指测试信号引线)产生的静电进行释放，对显示面板起静电防护作用。
进一步，在具体实施方式中可以将该静电释放体122的宽度(包括本体和第一绝缘层的总宽度)设置为小于或者等于导电焊垫121的宽度，将静电释放体122的长度设置为小于或者等于导电焊垫121的长度。当然，在实际应用中可以根据实际情况来选择和设计静电释放体122和导电焊垫121之间的尺寸关系，此处不做具体限定。本实施例中，静电释放体122和导电焊垫121之间的宽度设置为相同，静电释放体122的长度小于导电焊垫121，静电释放体122的长和宽之比可以设置为2:1，且静电释放体122和导电焊垫121二者的重叠面积小于静电释放体122在显示面板100的衬底基板101上的投影面积。
请继续结合图1至图3，导电焊垫121包括在远离衬底基板101方 向上依次层叠设置的第二绝缘层1211及第一金属层1212，其中，所述静电释放体122的第一绝缘层1222和第二绝缘层1211部分交叠。其中，第一绝缘层1222和第二绝缘层1211交叠的部分设置若干第二过孔1224，第二绝缘层1211对应第二过孔1224的位置设置若干第三过孔1213，静电释放体122通过第二过孔1224及第三过孔1213和第一金属层1212电连接。其中，本实施例中的导电焊垫121(测试焊垫)的膜层结构可以仅由第二绝缘层1211及第一金属层1212组成，不影响对显示面板100中显示区110进行测试。
可以理解的是，在具体应用场景中当驱动IC给导电焊垫121一测试驱动信号，该测试信号的传输路径为依次经过第一金属层1212、经过第二绝缘层1211上的第三过孔1213以及第一绝缘层1222上的第二过孔1224传输至静电释放体122的本体1221上，经过静电释放体本体1221对测试信号进行静电消除后通过第一绝缘层1222上的第一过孔1223连接的信号引线200传输至显示面板100的显示区110中，如此一来便可提升显示面板100的静电防护能力，保护显示面板100的测试信号引线不被烧伤。
本实施例中发明人发现将静电释放体122的长宽比设置为2:1时，该静电释放体122清除显示面板100中测试信号引线产生静电的能力更好，其静电防护能力更强。
此外，参见图4和图5，本实施例中还可以进一步包括第二金属层123，该第二金属层123设置于第一绝缘层1222和第二绝缘层1211交叠处，该第二金属层123对应若干第二过孔1224或第三过孔1213的位置设置有若干第四过孔1231，静电释放体122通过第四过孔1231电连接第一金属层1212。
可以理解的是，上述实施方式中静电释放体122的本体1221靠近显示区一侧的边缘和超出导电焊垫121靠近显示区一侧的边缘，在其它实施例中，该静电释放体122的本体1221靠近显示区一侧的边缘还可以刚好平齐导电焊垫121靠近显示区一侧的边缘，但是该静电释放体不能完全被导电衬垫121全部覆盖，原因在于：
结合图2-5，假设当静电释放体122和导电焊垫完全交叠，即静电释放体122的本体1221靠近显示区的一侧完全覆盖在导电焊垫121下时，即静电释放体122的第一绝缘层1222的上表面完全被导电焊垫121上的第二绝缘层1211给覆盖，且此时第一绝缘层1222的上表面不能再设置第一过孔1223连接信号线200，也就是说驱动IC给导电焊垫121一测试驱动信号，该测试信号不会经过静电释放体122进行静电消除。
因此，在设计静电释放体122和导电焊垫121交叠时，静电释放体122靠近显示区一侧的边缘超过导电焊垫121靠近显示区一侧的边缘，否则静电释放体122不能起到消除面板静电的作用。
此外，发明人还发现在显示面板的非显示区中将静电释放体和导电焊垫进行完全交叠时(此时静电释放体的本体靠近显示区一侧的边缘和导电焊垫靠近显示区一侧的边缘平齐)，可以实现对信号进行静电消除，提升显示面板静电防护能力的同时，还能最大限度的节省显示面板下边框的宽度，可用于分配给个信号源走线，增大信号源走线的宽度，从而防止信号线发生烧伤对显示面板造成影响。
发明人还发现将静电释放体的本体靠近显示区一侧的边缘和导电焊垫靠近显示区一侧的边缘平齐，可以保证导电焊垫的长度不被压缩，满足工艺生产的需求。
可以理解的是，在其他实施方式中该导电焊垫还可以连接其他容易发生静电的信号引线，例如多路复用信号(Demux)、扫描电路的起始信号以及使能信号等等，其原理和上述实施方式相同，将静电释放体设置为和导电焊垫至少部分交叠，可以对显示面板中的信号引线起静电防护作用，防止其被烧毁，提升面板的静电防护能力。
上述实施方式中，通过将静电释放体和导电焊垫进行至少部分交叠，可以在实现对显示面板信号进行静电消除，提升显示面板静电防护能力的同时，还能最大限度的节省显示面板下边框的宽度，增加信号源走线的宽度，从而降低显示面板中信号线烧伤的风险，提高显示面板的生产良率。
参阅图6，图6为本申请显示面板第二实施方式的结构示意图，如 图6，本实施例中和第一实施方式大致相同，不同之处在于本实施例中静电释放体和导电焊垫的交叠面积小于静电释放体在显示面板上的投影面积且静电释放体的宽度小于导电焊垫的宽度，相同之处不再赘述，描述如下：
如图6，本申请提供的显示面板100定义有显示区110及显示区110外围的非显示区120。可选地，非显示区120不一定是围绕显示区110设置，非显示区120可以仅设置在显示区110外围的一侧边缘或者两侧边缘，或两侧边缘与底部边缘外围，或仅设置在底部边缘外围。
其中，显示区110中设置有多条信号引线111，可选地该多条信号引线111可以为栅极线、数据线、栅极扫描线以及数据扫描线等等，此处不做具体限定。
非显示区120设置有多个导电焊垫121及多个静电释放体122，本实施例中导电焊垫121可以为测试焊垫，也可以是其他导电焊垫，此处不做具体限定。
多个静电释放体122的一端通过多条信号引线111连接显示区110，且多个静电释放体122和多个导电焊垫121至少部分交叠且连接。本实施例中，静电释放体122的宽度设置为小于导电焊垫121的宽度，且静电释放体122和导电焊垫121之间的交叠面积为静电释放体122在显示面板100上投影面积的一半，当然也可以是其他的交叠面积此处不做具体限定。可以理解的是，除交叠面积不相同之外，本实施例中的静电释放体122的材料选择及膜层构造均和第一实施方式中的设计类似，参见第一实施方式中的具体描述，此处不再赘述。
进一步，参阅图7本申请中静电释放体122宽度还可以设置为大于导电焊垫121的宽度，可以理解的是，只要满足静电释放体122在和导电焊垫121进行交叠时，静电释放体122的本体靠近显示区一侧的边缘不超过导电焊垫121靠近显示区一侧的边缘，就可实现对显示面板信号进行静电消除，提升显示面板静电防护能力。同时，还能节省显示面板下边框的宽度，增加信号源走线的宽度，从而降低显示面板中信号线烧伤的风险，提高显示面板的生产良率。
上述实施方式，通过将静电释放体和导电焊垫进行至少部分交叠，可以在实现对显示面板信号进行静电消除，提升显示面板静电防护能力的同时，还能最大限度的节省显示面板下边框的宽度，增加信号源走线的宽度，从而降低显示面板中信号线烧伤的风险，提高显示面板的生产良率。
请参阅图8，图8为本申请显示装置一实施方式的结构示意图。如图8所示，该显示装置300包括壳体301以及上述的显示面板F。本申请中的显示装置300包括的显示面板F为本申请上述任一实施例中的显示面板。其中，该显示面板F的具体结构参见上文，此处不再赘述。
本申请所提供的显示装置300可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、智能穿戴显示装置、导航仪等任何具有显示功能的产品或部件。
综上所述，本领域技术人员容易理解，本申请提供一种显示面板及其显示装置，通过将静电释放体和导电焊垫进行至少部分交叠，可以在实现对显示面板信号进行静电消除，提升显示面板静电防护能力的同时，还能最大限度的节省显示面板下边框的宽度，增加信号源走线的宽度，从而降低显示面板中信号线烧伤的风险，提高显示面板的生产良率。
以上所述仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
