下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
在显示面板中，由于前置摄像头等元件的存在，显示面板中的感光区域需要具有较高的透过率，而为了提高感光区域的透过率，通常会将用于驱动感光区域内像素单元发光的像素电路设置在感光区域外。但是这种设计使得连接像素电路的走线对应的延伸长度增大，而导致显示面板出现显示不均等问题。
为了解决上述问题，本发明实施例提供了一种显示面板，请参阅图1至图4，显示面板具有第一区A1以及第二区A2，第一区A1的透过率大于第二区A2的透过率，显示面板包括第一像素单元10、第一像素电路20以及第一信号线30。第一像素单元10设置于第一区A1内，第一像素电路20位于第二区A2内并沿第二方向Y位于第一区A1的一侧，第一像素电路20与第一像素单元10连接。第一信号线30与设于第二区A2的第一像素单元10对应的第一像素电路20连接，第一信号线30包括在第一方向X上延伸的主体段31以及自主体段31一端分出的第一支路32和第二支路33，第一支路32连接第一像素电路20，第二支路33包括设于第二区A2内的第一段331，第一段331与主体段31分别位于第一区A1的两侧，第一方向X与第二方向Y相交。
图1示出本发明一种实施例的显示面板的俯视示意图，图2是图1中区域Q的局部放大结构示意图，图3是另一种示例中图1中区域Q的局部放大结构示意图，图4是单个第一像素电路20以及单个第一像素单元10 的连接结构简图。其中图3和图2展示了不同的层结构，图2中展示了区域Q处第一像素单元10的排布方式，图3与图2不同之处在于图3展示出来第一像素电路20的排布结构图，并保留了第一区A1内的多个第一像素单元10。
显示面板至少具有第一区A1和第二区A2两个区域，第一区A1为显示面板的感光区域，感光元件(图中未示出)设置于第一区A1内，其中感光元件包括但不限于前置摄像头、听筒以及红外感应元件等部件。同时第一区A1内还设置有第一像素单元10，以使第一区A1能够实现显示功能，从而满足全面屏需要。对于第一区A1的形状，本发明实施例不作限制。第一区A1的轮廓可以呈圆形、方形、多边形或者水滴状等。
第二区A2围设在第一区A1的外周侧，第二区A2为显示面板的正常显示区域，即第二区A2内同样设置有像素单元。通常情况下，为了实现第一区A1的感光功能，会将第一区A1的透过率设置为大于第二区A2的透过率。示例性地，可以适度降低第一区A1内第一像素单元10的密度，以提高第一区A1的透过率；或者也可以降低第一区A1内第一像素单元10的尺寸大小，从而提高第一区A1的透过率。在本实施方式中，第二区A2围设在第一区A1的外周侧，第二区A2可以是完全或部分围绕第一区A1设置。
第一像素电路20用于驱动第一区A1内的第一像素单元10实现发光功能，对于第一像素电路20的结构，本发明实施例不作限制。示例性地，第一像素电路20可以采用7T1C或8T1C等形式。由于第一像素电路20设置在第一区A1内会降低该位置处的透过率，因此本发明实施例将第一像素电路20设置在第二区A2内，并且沿第二方向Y位于第一区A1的一侧。即第一像素电路20的设置不会对第一区A1的透过率产生影响，从而能够更好地实现第一区A1的感光效果。
第一信号线30与第一像素电路20连接，第一信号线30能够将对应的驱动信号传递至第一像素电路20，并通过第一像素电路20驱动位于第一区A1内的第一像素单元10实现发光功能。对于第一信号线30的具体类型，本发明实施例不作限制。
第一信号线30包括在第一方向X延伸的主体段31，第一方向X与第二方向Y相交，示例性地，第一方向X垂直于第二方向Y。本发明实施例提到的主体段31沿第一方向X延伸，指的是主体段31在第一方向X上存在一定的延伸距离，可以是主体段31各处的延伸方向均为第一方向X，也可以是主体段31中部分延伸方向是X，部分的延伸方向可相对于第一方向X存在倾斜。主体段31本身也可以并非直线结构，例如为曲线等结构，也可以为部分直线部分曲线的结构。
主体段31至少部分位于第一区A1在第一方向X上的一侧，在相关技术中，由于第一像素电路20沿第二方向Y位于第一区A1的一侧，因此主体段31会相继在第一方向X和第二方向Y上继续延伸，从而与第一像素电路20实现连接，并跨域至第一区A1在第一方向X上的另一侧。这种设计会导致第一信号线30的整体延伸长度增大，延伸长度的增加会产生额外的电阻和电容，从而增大第一信号线30对第一像素电路20的充放电时间，容易出现显示不均等问题。
而在本发明实施例中，主体段31的一端分出了第一支路32和第二支路33两条支路，第一支路32用于连接第一像素电路20，第二支路33包括第一段331，第一段331与主体段31分别位于第一区A1的两侧。本发明实施例中提到的“第一段331与主体段31分别位于第一区A1的两侧”指的是：第一段331和主体段31被第一区A1所隔开，其中第一段331可以与主体段31位于平行于第一方向X的同一直线上，也可以位于不同直线上，即两者相对错位设置，本发明实施例对此不作限制。
由第一段331与主体段31分别位于第一区A1的两侧可知，第二支路33在第一方向X上跨过第一区A1并且不会和与第一支路32相连的第一像素电路20连接。相较于相关技术中，第一信号线30绕线连接至对应第一像素电路20，然后从该第一像素电路20继续延伸连接至其他第一像素电路20，从而在第一方向X上跨域第一区A1的方案，本发明实施例中的第一支路32和第二支路33的设计可以有效减小第一信号线30的总延伸长度。
需要说明的是，本发明实施例中提到的第一信号线30的总延伸长度指的是，第一信号线30中各部分的延伸长度之和。具体地说，本发明实施例 中第一信号线30的总延伸长度至少包括主体段31的延伸长度、第一支路32的延伸长度以及第二支路33的延伸长度之和。
此外，主体段31可以完全位于第一区A1在第一方向X上的一侧，也可以部分位于第一区A1在第一方向X上的一侧，另外部分位于第一像素电路20朝向第一区A1的一侧，本发明实施例对此不作限制。
本发明实施例中的第一信号线30包括有第一支路32和第二支路33，通过设置支路结构，从而减小第一信号线30的整体延伸长度，降低第一信号线30对第一像素电路20的充放电时间，降低显示面板出现显示不均的风险，提高显示可靠性。
需要说明的是，第一信号线30除了连接于第一像素电路20外，还可以同时连接多个其他像素电路，本发明实施例对此不作限制。
在一些实施例中，如图4所示，第二支路33包括第一段331，以及连接第一段331和主体段31的第二段332，第一段331与主体段31沿第一方向X位于第一区A1的两侧，第一段331与第二段332在交界点T处相交。图4为示意简图，显示面板的实际走线设计中交界点T可等效为第三像素单元70的位置处。
主体段31中大部分结构位于第一区A1在第一方向X上的一侧，而第一段331则在第一方向X上位于第一区A1的另一侧，其中第一段331也可以沿第一方向X延伸成型。第二段332在第一方向X上具有相对的两端，其中一端与第一段331连接，另一端与主体段31连接。
需要说明的是，对于第二段332的材质以及具体走线布局，本发明实施例不作限制。示例性地，第二段332可以采用与第一段331相同的材质，也可以采用与第一段331不同的材质。并且第二段332可以在第二区A2内围绕第一区A1延伸设置，也可以穿过第一区A1延伸设置。
在一些实施例中，如图4所示，显示面板还包括在第一方向X上位于第一区A1两侧的第三像素电路70和第四像素电路80以及多个第五像素电路90，第三像素电路70连接于第一段331，第四像素电路80和第五像素电路90连接于主体段31，第三像素电路70、第四像素电路80和第五像素电路90沿第一方向X排布于一条线上。
单个第一信号线30除了能够用于连接第一像素电路20外，还能够连接第三像素电路70、第四像素电路80以及多个第五像素电路90，对于第五像素电路90的数量，本发明实施例不作限制。
第四像素电路80和第五像素电路90位于第一区A1的同一侧，第三像素电路70位于第一区A1的另一侧。第三像素电路70、第四像素电路80和第五像素电路90设置在同一直线上，第一信号线30上的信号能够一同传递至第三像素电路70、第四像素电路80和第五像素电路90上，以驱动与第三像素电路70、第四像素电路80和第五像素电路90相对应的像素单元发光。需要说明的是，与第三像素电路70、第四像素电路80和第五像素电路90对应的像素单元位于第二区A2内。
在一些实施例中，如图4所示，主体段31与第一支路32的连接点S在第一方向X上位于第一区A1的一侧。
在本发明实施例中，主体段31完全位于第一区A1在第一方向X的一侧，示例性地，结合图4来说，主体段31的一端位于显示面板的下方，并沿第一方向X向靠近第一区A1的方向继续延伸，直至延伸至第一区A1下方，然后主体段31分支出第一支路32和第二支路33两条支路结构，第一支路32直接连接至第一像素电路20，第二支路33绕过第一区A1并延伸至显示面板的上方。
进一步地，在一些实施例中，第一支路32包括沿第二方向Y延伸并连接主体段31的第一支段321，以及沿第一方向X延伸并连接第一支段321和第一像素电路20的第二支段322。
由于主体段31与第一支路32的连接点S与第一像素电路20错位设置而在第一方向X上和第二方向Y上均存在错位距离，因此本发明实施例的第一支路32设置有第一支段321和第二支段322。其中，第一支段321自连接点S延伸至与第一像素电路20在第二方向Y上对应的位置处，第二支段322自第一像素电路20延伸至在第一方向X上对应第一像素电路20的位置处而与第一支段321交汇。
需要说明的是，第一支路32除了包括第一支段321和第二支段322外，还可以包括有其他支段，具体情况需要根据显示面板内部结构的布局决定。 此外，与主体段31相同的是，第一支段321和第二支段322中至少一者可以并非直线结构，也可以为曲线等结构，甚至也可以为部分直线部分曲线的结构，只要满足第一支段321的整体延伸趋势是第二方向Y，第二支段322的整体延伸趋势是第一方向X即可。
在一些实施例中，主体段31、第一支路32的连接点S与第一区A1在第二方向Y上位于第一像素电路20的同一侧。主体段31的其中一部分位于第一区A1在第一方向X上的一侧，另外一部分位于第一像素电路20靠近第一区A1的一侧，其中主体段31中位于第一像素电路20靠近第一区A1的一侧的部分可以位于第一区A1内，也可以位于第一区A1与第一像素电路20之间，本发明实施例对此不作限制。
在本发明实施例中，由于主体段31与第一支路32的连接点S在第二方向Y上位于第一像素电路20靠近第一区A1的一侧，因此第一支路32可以仅沿第二方向Y延伸便可实现与第一像素电路20的连接，即第一支路32可以去掉第二支段，仅依靠第一支段实现与第一像素电路20的连接，这种设计可以简化第一支路32的结构并降低第一支路32的延伸长度，进一步降低显示面板出现显示不均的风险。
在一些实施例中，如图4和图5所示，第二段332围绕第一区A1的外周侧延伸。
第二段332连接第一段331和主体段31，且第二段332位于第二区A2内。在此基础上，本发明实施例将第二段332围绕第一区A1的外周侧延伸，换言之，第二段332靠近第一区A1设置并且第二段332的形状与第一区A1的轮廓形状相适配，进一步，请参阅图6，第二段332可以设置为贴靠第一区A1的边缘延伸。相对于第二段332位于第二区A2内的其他走线方式而言，这种设计能够极大程度降低第二段332的延伸长度，从而降低第一信号线30的整体延伸长度，降低发生显示不均的风险，提高显示可靠性。
在一些实施例中，第一区A1呈圆形结构，第二段332包括弧形段。
当第一区A1为圆形结构时，为了使得第二段332的形状更适配于圆形结构，因此本发明实施例将第二段332内设置有弧形段，弧形段能够与第 一区A1的外轮廓更加匹配，从而能够有效减少第二段332的长度。需要说明的是，当主体段31与第一支路32的连接点在第二方向Y上位于第一像素电路20靠近第一区A1的一侧时，此时主体段31也可以包括有弧形段，并且弧形段围绕第一区A1的外周侧延伸，以此来减少主体段31的延伸长度。
在一些实施例中，请参阅图7，第一区A1呈多边形结构，第二段332包括折线段。其中，多边形结构可以为三边形、四边形以及五边形等。
当第一区A1为多边形结构时，为了使得第二段332的形状更适配于多边形结构，因此本发明实施例将第二段332内设置有折线段，折线段能够与第一区A1的外轮廓更加匹配，从而能够有效减少第二段332的长度。需要说明的是，当主体段31与第一支路32的连接点在第二方向Y上位于第一像素电路20靠近第一区A1的一侧时，此时主体段31也可以包括有折线段，并且折线段围绕第一区A1的外周侧延伸，以此来减少主体段31的延伸长度。
在一些实施例中，请参阅图8，第二段332位于第一区A1内。
第二段332用于连接主体段31和第一段331，而将第二段332设置在第一区A1内，可以减少第二段332出现不必要的绕线的风险，降低第二段332的长度，从而进一步降低第一信号线30的整体延伸长度。示例性地，第二段332为直线结构，以此能够进一步降低第二段332的延伸长度。
在本实施例中，第二段332为透明结构。
由于第二段332位于第一区A1内，因此第二段332的存在会对显示面板在第一区A1内的透过率产生影响。在此基础上，本发明实施例将第二段332设置为透明结构，透明结构自身对显示面板的透过率的影响较小，即这种设计可以降低第二段332对第一区A1透过率的影响，在满足第一区A1透过率的前提下，进一步降低第二段332的延伸长度，提高显示面板的显示可靠性。
需要说明的是，第二段332的材料可以与第一段331或主体段31中至少部分结构的材料一致，也可以不一致。示例性地，第一段331和主体段31均包括金属导电材料，第二段332包括氧化铟锡(Indium tin oxide， ITO)、氧化铟锌、掺杂银的氧化铟锡和掺杂银的氧化铟锌中的至少一种。
在一些实施例中，如图8所示，第二段332沿第一方向X延伸。本发明实施例中第二段332沿第一方向X延伸指的是，第二段332的整体延伸趋势是沿第一方向X，而第二段332本身可以为直线结构，也可以为曲线或其他结构，本发明实施例对此不作限制。
由前述内容可知，主体段31沿第一方向X延伸，第一段331位于第一区A1背离主体段31的一侧。在此基础上，为了使第二段332能够实现第一段331与主体段31之间的连接以及尽可能降低第二段332的延伸长度，本发明实施例将第二段332设置在第一区A1内，并使其沿第一方向X延伸成型。这种设计可以最大程度地降低第二段332的延伸长度，降低显示面板发生显示不均的风险。可选地，第二段332沿第一方向X径直穿过第一区A1。
在一些实施例中，请参阅图9，沿第一方向X延伸且经过第一像素电路20的第一虚拟延长线41与沿第二方向Y延伸且经过第三像素电路70的第二虚拟延长线42相交于虚拟交点O。其中，第一像素电路20到虚拟交点O的距离与第三像素电路70到虚拟交点O的距离之和大于第二段332中由第三像素电路70至第四像素电路80的延伸长度。
第一虚拟延长线41与第二虚拟延长线42均为假设的线段结构，两者分别沿第一方向X和第二方向Y延伸，并在虚拟交O点处相交。第一像素电路20到虚拟交点O的距离即为第一虚拟延长线41的长度，第三像素电路70到虚拟交点O的距离即为第二虚拟延长线42的长度。
在相关技术中，显示面板会在第一虚拟延长线41以及第二虚拟延长线42位置处设置导线结构，从而形成连接第一像素电路20的对应信号线。结合图8具体地说，连接于第一像素电路20的信号线通常包括主体段31、连接主体段31以及第一像素电路20的第一支路32、连接第一像素电路20以及第三像素电路70并沿第一虚拟延长线41和第二虚拟延长线42路径延伸的导线结构、第一段331以及连接第一段331和第四像素电路80的导线结构。
而在本发明实施例中，用于连接第一像素电路20的第一信号线30包 括主体段31以及由主体段31一端分出的第一支路32和第二支路33，而第二支路33包括位于第一区A1背离主体段31一侧的第一段331以及连接第一段331和主体段31的第二段332。
综上，通过对比可知，本发明实施例中的第一信号线30相较于相关技术中连接第一像素电路20的对应信号线，增加了第二段332中连接第三像素电路70以及第四像素电路80的部分，但是减少了连接于第一像素电路20并并沿第一虚拟延长线41和第二虚拟延长线42路径延伸的导线结构。因此在此基础上，通过控制第二段332的延伸长度小于第一虚拟延长线41与第二虚拟延长线42的延伸长度之和，从而使得本发明实施例中的第一信号线30的延伸长度小于相关技术中连接第一像素电路20的对应信号线的延伸长度，进而相对于相关技术，本发明实施例提供的显示面板更难出现显示不均等问题，并且有利于提高显示面板的使用寿命。
在一些实施例中，第一区A1与第一像素电路20之间的间距不小于2mm。
可以理解的是，若第一区A1与第一像素电路20之间的间距越大，则对应的第二虚拟延长线的延伸长度越大，但是第二段332的延伸长度不会受到第一区A1与第一像素电路20之间的间距的影响。进一步地，在第一区A1与第一像素电路20之间的间距越大的情况下，本发明实施例中的第一信号线30相较于相关技术中连接第一像素电路20的对应信号线的延伸长度之差越大。在这种情况下，本发明实施例提供的显示面板能够进一步降低发生显示不均的风险，提高显示面板的显示可靠性。
在一些实施例中，请参阅图10，第一信号线30的数量为多个。
通常情况下，位于第一区A1内的第一像素单元10的数量为多个，因此与其对应的第一信号线30以及第一像素电路20的数量也为多个，且多个第一像素电路20沿第二方向Y排布，多个第一像素电路20以及多个第一信号线30相互配合连接，并实现对位于第一区A1内的多个第一像素单元10的发光控制。
需要说明的是，第一像素电路20与第一像素单元10的数量可以是对应相同的，也可以是不同的。具体地说，位于第一区A1内的多个第一像 素单元10可以与多个第一像素电路20一一对应，或者一个第一像素电路20可以同时驱动多个第一像素单元10发光，从而降低第一像素电路20的排布密度，本发明实施例对此不作限制。
在一些实施例中，在垂直于显示面板厚度方向上的表面，多个第一信号线30中的第二段332的正投影至少部分交叠设置。
本发明实施例中提到的显示面板的厚度方向指的是，显示面板中多个膜层的层叠方向，即显示面板中的多个膜层沿显示面板的厚度方向依次层叠设置。进一步地，本发明实施例中提到的垂直于显示面板厚度方向上的表面指的是，与显示面板厚度方向相垂直的任意平面。
第二段332用于连接第一段331和主体段31，第二段332可以位于第二区A2内并围绕第一区A1的外周侧延伸设置，第二段332也可以位于第一区A1内。在此基础上，本发明实施例将不同第一信号线30设置在不同膜层中，并将多个第一信号线30中的第二段332的正投影至少部分交叠设置，从而能够降低第一区A1或第一区A1外周侧附近的走线密度。
具体地说，当第二段332位于第一区A1内，多个第一信号线30中的第二段332的正投影至少部分交叠设置，可以降低第二段332对第一区A1出透过率的影响，从而提高显示面板的感光效果。当第二段332位于第二区A2内并围绕第一区A1的外周侧延伸设置，多个第一信号线30中的第二段332的正投影至少部分交叠设置，可以减少第一区A1周围走线密度，从而降低第一区A1周侧出现明显阴影的风险，提高显示面板的显示效果。
在一些实施例中，多个第一信号线30中的第二段332在显示面板厚度方向上的正投影沿第二方向Y并排设置。
在本发明实施例中，多个第一信号线30可以位于相同膜层，也可以位于不同膜层。多个第一信号线30的正投影在第二方向Y上并排设置，当多个第一信号线30位于相同膜层时，相邻第一信号线30之间夹设有绝缘材料以相互绝缘。
综上，本发明实施例中的多个第一信号线30中第二段332可以在在垂直于显示面板厚度方向上的表面交叠设置，也可以相互并排设置，具体布置方式可以根据显示面板的实际膜层结构来设计。
在一些实施例中，请参阅图11，第一像素电路20的数量为多个，同一第一信号线30连接多个第一像素电路20。
在本实施例中，同一第一信号线30可以连接于多个第一像素电路20，这种设计可以降低第一信号线30的数量，并降低第一信号线30对第二区A2内空间的占用，以使第二区A2能够布置更多的第一像素单元10，以实现更好地显示效果。
在一些实施例中，第一支路32的数量为多个。
一个第一信号线30中包括多个第一支路32，多个第一支路32分别连接于不同第一像素电路20，从而能够减少第一信号线30的总数量，提高显示面板的显示效果。
需要说明的是，单个第一信号线30中的多个第一支路32相互间可以存在有重叠的部分，即多个第一支路32可以共用部分结构实现信号传递。或者多个第一支路32之间也可以不存在重叠的部分，本发明实施例对此不作限制。
在一些实施例中，第一信号线30为数据线，数据线沿第一方向X延伸，扫描线沿第二方向Y延伸，多个第一像素电路20在第二方向Y上位于数据线的至少一侧。第一像素电路20与对应的第一像素单元10的连接方向与第二方向Y一致，所述第二方向为显示面板短边所在方向。
显示面板内设置有交叉设置的数据线和扫描线，数据线沿第一方向X延伸用于传输数据信号，扫描线沿第二方向Y延伸用于传输扫描信号。其中，数据线与扫描线均用于驱动第一区A1内第一像素单元10的发光。部分数据线需要跨越第一区A1设置，在这种情况下，多个第一像素电路20可以设置在数据线的至少一侧，并在第二方向y上并排设置，数据线中的第一支路能够实现数据线与第一像素电路20之间的电连接。
可替代地，第一信号线30也可以为扫描线，此时扫描线沿第一方向X延伸，数据线沿第二方向Y延伸，多个第一像素电路20在第二方向Y上位于扫描线的至少一侧。第一像素电路20与对应的第一像素单元10的连接方向与第二方向Y平行，所述第二方向为显示面板长边所在方向。
与数据线相同的是，部分扫描线同样需要跨越第一区A1设置，在这 种情况下，多个第一像素电路20可以设置在扫描线的至少一侧，并在第二方向y上并排设置，扫描线中的第一支路能够实现扫描线与第一像素电路20之间的电连接
发明在上述两个实施例中，通过对数据线和扫描线中至少一者的走线方式进行了调整，以降低显示面板出现显示不均的风险，提高显示可靠性。
在一些实施例中，请参阅图4和图12，显示面板还包括第二像素电路50以及第二信号线60，第二像素电路50位于第二区A2内并沿第二方向Y位于第一区A1的一侧，第二像素电路50与位于第一区A1内的第一像素单元10连接。第二信号线60与设于第一区A1的第一像素单元10对应的第二像素电路50连接，第二信号线60包括在第一方向X上位于第一区A1两侧的第三段61和第四段62，以及连接第三段61和第四段62的第五段63，第五段63连接第二像素电路50。
第二像素电路50与第一像素电路20类似，均用于驱动第一区A1内的第一像素单元10实现发光功能，对于第二像素电路50的结构，本发明实施例不做限制。示例性地，第二像素电路50可以采用7T1C或8T1C等形式。第二信号线60与第二像素电路50连接，第二信号线60能够将对应的驱动信号传递至第二像素电路50，并通过第二像素电路50驱动位于第一区A1内的第一像素单元10实现发光功能。对于第二信号线60的类型，本发明实施例不做限制。示例性地，第二信号线60为数据线和扫描线中的一者。
第二信号线60中的第三段61和第四段62分别在第一方向X上位于第一区A1的两侧，第五段63用于连接第三段61和第四段62，同时第二像素电路50位于第五段63的延伸路径上，以使第五段63能够同时连接第二像素电路50。示例性地，第五段63包括电连接第二像素电路50和第四段62的第一子段631，以及电连接第二像素电路50和第五段63的第二子段632。
在本发明实施例中，第一像素电路20以及第二像素电路50均用于驱动第一区A1内的第一像素单元10实现发光，针对于第一像素电路20和第二像素电路50位置的不同，本发明实施例分别采用第一信号线30和第二 信号线60实现信号传递效果。与第一信号线30不同的是，第二信号线60上未设置有支路结构，第二信号线60自身延伸路径经过第二像素电路50，从而能够实现与第二像素电路50的连接。第一信号线30和第二信号线60的差异化设计，能够满足显示面板内部不同位置处像素电路的连接要求，从而具有较强的灵活性。
在一些实施例中，第二像素电路50位于第一像素电路20靠近第一区A1的一侧。
由前述内容可知，第一区A1与第一像素电路20之间的间距越大，第一信号线30相较于相关技术中连接第一像素电路20的对应信号线的延伸长度之差越大，即第一信号线30的存在则可以进一步降低显示面板发生显示不均的风险。
而针对于第二像素电路50来说，由于其采用第二信号线60实现连接，为了降低第二信号线60导致显示面板出现显示不均等问题，因此本发明实施例将第二像素电路50设置在第一像素电路20靠近第一区A1的一侧，从而提高显示面板的显示可靠性。
具体地说，假设第二像素电路50采用第一信号线30的方式实现连接，与第二信号线60的方式相比，第一信号线30的连接方式增加了第二段中部分结构的长度，但是减少了第一子段631的长度。进一步地，由于第二像素电路50相较于第一像素电路20更靠近第一区A1设置，因此第二像素电路50中的第一子段631的长度较小，第一子段631的延伸长度小于第二像素电路50所对应的第二段的长度，因此对于第二像素电路50而言，采用第二信号线60可以降低出现显示不均的风险，提高显示可靠性。示例性地，第一区A1与第二像素电路50之间的间距不大于2mm。
第二方面，请参阅图13，本发明实施例提供了一种显示装置，包括前述任一实施方式中的显示面板。
需要说明的是，本发明实施例提供的显示装置，具有前述任一实施方式中显示面板的有益效果，具体内容请参照前述对于显示面板有益效果的描述，本发明实施例不再赘述。
