请参阅图1及图2，本发明实施方式的显示面板10包括显示区域12和连接显示区域12的引线区域14。引线区域14形成有用于连接显示区域12与外部电路20的引线142。引线区域14绕折弯轴弯折形成折弯区域144。引线142与折弯轴交叉且直线横跨折弯区域144。
在本发明实施方式的显示面板10中，引线区域14可以绕折弯轴弯折至显 示区域12的背面，从而减小显示面板10的边框，提高显示区域12相对于显示面板10的占比，而且，由于引线142直线横跨折弯区域144，因而可以减小引线142在绕折弯轴弯折时所受的侧向应力，降低引线142在弯折状态下出现不良的概率。
可以理解，显示区域12可以包含多个显示像素，这些显示像素由与显示区域12连接的外部电路20驱动或控制。引线142用于在显示区域12与外部电路20之间传递信号。显示面板10可以包括外部电路20。
请再次参阅图1，在一个例子中，外部电路20包括电路板22和设置在电路板22上的驱动芯片24。引线142连接显示区域12与电路板22。
请参阅图3，在另一个例子中，外部电路20包括驱动芯片24。引线142连接显示区域12与驱动芯片24。
具体地，驱动芯片24可以为gate(栅极)驱动芯片和SD(漏极/源极)驱动芯片。
请参阅图4，在某些实施方式中，显示面板10包括设置在显示区域12两侧的GOA(Gate Driver on Array，阵列基板栅极驱动)单元26。外部电路20连接GOA单元26。
在某些实施方式中，显示面板10包括柔性显示面板。
当显示面板10为柔性显示面板时，显示面板10还可以包括可弯曲的衬底，如此，可以通过弯折引线区域14的衬底来弯折引线142以实现对显示面板10 的边框大小的控制，实现显示区域12相对于显示面板10的占比的最大化。
在某些实施方式中，显示面板10包括柔性OLED(Organic Light-Emitting Diode，有机发光二极管)。
具体地，柔性OLED具有低功耗、可弯曲的优点。
在某些实施方式中，显示区域12和引线区域14平展时显示面板10呈矩形。显示区域12呈矩形并包括垂直连接的第一连接边122和第二连接边124。引线区域14与第一连接边122和第二连接边124连接。
如此，外部电路20可以通过引线142驱动或控制显示区域12显示。
在某些实施方式中，引线142包括至少一束引线142，同一束的引线142的长度相同。
具体地，以图3为例，图3中的显示面板10包括6束引线142，其中3束引线142连接显示区域12的第一连接边122，另外3束引线142连接显示区域12的第二连接边124。而每束引线142中的多根引线142的长度相等。与6束引线142相对应地，外部电路20包括横向的3个电路板22和设置在电路板22上的驱动芯片24，和纵向的3个驱动芯片24。
由于引线142用于在显示区域12与外部电路20之间传递信号，因而为了保证信号传递的同步，较佳地，同一束引线142中的每根引线142的线程一致，即长度相同。
请再次参阅图2，在某些实施方式中，同一束的引线142包括第一直线段 1422、斜线段1424、折线段1426和第二直线段1428。第一直线段1422与显示区域12连接且平行布置。斜线段1424与第一直线段1422连接且呈三角状聚拢布置。折线段1426与斜线段1424连接且直线横跨折弯区域144。第二直线段1428的一端与折线段1426连接且平行布置。第二直线段1428的另一端连接外部电路20。多个第一直线段1422布置的宽度d1大于多个第二直线段1428布置的宽度d2。
如此，引线142可以逐步聚拢收缩，以便与外部电路20连接，减少占用的空间。而且折线段1426直线横跨折弯区域144，可以避免在折弯区域144出现拐角，降低折弯区域144的引线142在弯折后出现不良的概率。
可以理解，由于本发明实施方式的折弯区域144内不存在拐角和沿横向排布的引线142，因而整个折弯区域144都可以设置横向的折弯轴。
在某些实施方式中，折线段1426多次直线横跨折弯区域144。
如此，引线142折绕多次，有利于收容引线142，减小引线区域14的纵向宽度。折线段1426具体直线横跨折弯区域144的次数可以配合引线142的长度进行设计。
在某些实施方式中，多个折线段1426横跨折弯区域144的次数相等。
例如，以图2为例，所有的引线142均横跨折弯区域144三次，即绕折两次形成三段线段。如此，每个折线段1426的横向宽度一致或者说相邻的两个折线段1426的间隔距离相等，便于在制造显示面板10时的引线142排布。
本发明实施方式的引线142的排布在不增加设计的复杂度和工艺的整合难度的前提下，可以兼顾每根引线142的长短一致，进而保证负载一致。
需要指出的是，如图2所示的引线142的结构仅为引线142的一种设计方式，在其他实施方式中，引线142还可以根据需要采用其他的弯折和排布形式。
在某些实施方式中，引线142与折弯轴之间的夹角范围为60°-120°。
当引线142沿折弯轴弯折时，引线142受到与折弯轴垂直并由折弯轴向两侧方向的应力。而当引线142与折弯轴之间的夹角范围为60°-120°时，引线142在弯折时所受的侧向应力较小，应力的主要分量为平行于导线的方向，因而对导线造成的影响较小。
在某些实施方式中，引线142与折弯轴垂直。
同上，当引线142沿折弯轴弯折时，引线142受到与折弯轴垂直并由折弯轴向两侧方向的应力。而在本发明实施方式中，引线142与折弯轴垂直，也即是说，应力的方向与引线142平行。因而，引线142受到的侧向应力为零。如此，可以大大减少降低引线142在弯折状态下出现不良的概率。
本发明实施方式的显示区域12不限于为矩形，当显示区域12为非矩形时，例如，显示区域12为圆形或平行四边形等，引线142的排布也可以采用相同的设计方法，然后连接至显示区域12的输出端。
