本申请实施例提供了一种显示面板、显示面板制备方法及显示装置，以下将结合附图1至图15对显示面板、显示面板制备方法及显示装置的各实施例进行说明。
请参阅图1至图3，本申请实施例提供的一种显示面板，显示面板包括：基板1；触控层2，设于基板1一侧，触控层2包括触控电极20；电路板3，沿平行于基板1所在平面的方向，电路板3和触控层2相邻设置；触控走线4，触控走线4包括不同层的第一触控走线段41和第二触控走线段42，第一触控走线段41和触控电极20电连接；第二触控走线段42和电路板3电连接，第一触控走线段41通过至少两个搭接部L和同一段第二触控走线段42电连接。
本发明实施例所提供的显示面板包括基板1、触控层2、电路板3以及触控走线4，由于第一触控走线段41和第二触控走线段42位于不同层，为使两者连接，设置搭接部L以实现第一触控走线段41和第二触控走线段42之间的连接，且在本实施例中，第一触控走线段41通过至少两个搭接部L和同一段第二触控走线段42电连接。通过将搭接部L的数量设置为至少两个，以实现冗余设计，保证第一触控走线段41和第二触控走线段42之间出现偏位等问题时，第一触控走线段41和第二触控走线段42之间能够通过至少一个搭接部L连接，保证至少有一个搭接部L能够正常工作，降低工艺要求，提高了显示面板的生产良率及性能。
在本实施例中，第一触控走线段41和触控电极20电连接；第二触控走线段42和电路板3电连接。在第一触控走线段41和第二触控走线段42通过搭接部L连接后，可以通过第一触控走线段41、第二触控走线段42以及搭接部L所形成的线路进行触控电极20和电路板3之间的信号传输，实现触控检测。
在现有技术中，第一触控走线段41和第二触控走线段42之间通过一个搭接部L连接。在制备显示面板时，由于设计时工艺偏位或者屏体涨缩导致的对位不准确时，会导致搭接部L被误刻蚀，导致第一触控走线段41和第二触控走线段42之间无法正常连接，影响显示面板的生产良率及性能。
为解决上述问题，本发明实施例通第一触控走线段41通过至少两个搭接部L和同一段第二触控走线段42电连接，以通过增加搭接部L的数量，实现冗余设计，保证至少有一个搭接部L不会被刻蚀，能够正常工艺，提高了显示面板的生产良率及性能。

需要说明的是，由于触控层2设于封装层7背离基板1一侧，因而，为便于和触控电极20连接，第一触控走线段41也设于封装层7背离基板1一侧，而第二触控走线段42位于封装层7下方的阵列层5内。根据实际需要，第二触控走线段42和导电层M中至少一层同层设置，即第二触控走线段42和同层的导电层M可以通过同一道工艺一同形成，两者的材料相同，以降低生产成本，简化生产流程，便于制备。

可选的，封装层7还包括位于第二封装层72背离基板1一侧的第三封装层73，第三封装层73的材料包括无机材料，在有机封装层7外继续增设一层无机封装层7能够进一步提高封装层7的封装效果；在本实施例中，第三封装层73的材料可以和第一封装层71的材料相同，也可以不同，并无特殊限定。
可选的，第一封装层71的材料和第三封装层73的材料相同，使得第一封装层71和第三封装层73可以选用相同的设备进行制备，能够简化显示面板的制备工艺。
考虑到搭接部L通常采用过孔K并在过孔K内设置导电部C的形式，以实现第一触控走线段41和第二触控走线段42之间连接，若第一触控走线段41和第二触控走线段42在沿垂直于基板1所在平面方向上的距离较大，且两者之间具有多层绝缘层J，搭接部L需要设置多个相连接的过孔K才能实现第一触控走线段41和第二触控走线段42之间连接，但由于工艺原因，过孔K之间会形成一定的阶梯或者坡度，导致搭接部L中的导电部C可能会出现断裂。
请参阅图6至图8，为了避免出现上述问题，显示面板还包括设于第一触控走线段41和第二触控走线段42之间的过渡连接层H，第一触控走线段41通过搭接部L和过渡连接层H电连接，过渡连接层H和第二触控走线段42电连接。
在本实施例中，第一触控走线段41先通过搭接部L和过渡连接层H电连接，之后过渡连接层H再通过过孔K等形式和第二触控走线段42电连接，过渡连接层H可以和阵列层5中的一层导电层M同层设置，只要保证过渡连接层H设于第二触控走线段42上方即可。

可以理解的是，第三导电层M3设于第一导电层M1、第二导电层M2的上方。因而，过渡连接层H可以和第三导电层M3同层设置，以便于过渡连接层H分别连接搭接部L以及第二触控走线段42。
需要说明的是，和同一第一触控走线段41所连接的搭接部L可以和同一过渡连接层H一同连接，如图7所示。或者，也可以使得和第一触控走线段41所连接的搭接部L中至少一者和一过渡连接层H连接，其他的搭接部L可以和第二触控走线段42直接连接，即和第一触控走线段41所连接的搭接部L中，部分搭接部L可以通过过渡连接层H和第二触控走线段42连接，部分搭接部L可以直接和第二触控走线段42连接，如图8所示。
在本实施例中，搭接部L包括过孔K以及位于过孔K内的导电部C，导电部C可以和第一触控走线段41或第二触控走线段42的材料相同，考虑到制备流程，导电部C可以和第一触控走线段41采用相同的材料制成。
可选的，根据实际需要，阵列层5还可以设置更多的导电层M，例如，阵列层5还包括设于第三导电层M3背离基板1一侧的第四导电层M4，过渡连接层H或第二触控走线段42可以和第四导电层M4同层设置。
请参阅图9，在一些可选的实施例中，在沿第一方向X上，相邻两条第二触控走线段42和不同的导电层M同层设置，第一方向X平行于基板1所在平面的方向。
可以理解的是，通过使得相邻两条第二触控走线段42不同层设置，可以增大第二触控走线段42的设置空间。根据实际需要，第二触控走线段42的线宽也能设置的更大，以保证显示面板的触控走线4的阻抗满足需求。
例如，相邻两条第二触控走线段42中的一条可以和第一导电层M1同层设置，另一条可以和第二导电层M2同层设置。当然，也可以使得第二触控走线段42和第三导电层M3或者其他导电层M同层设置，并无特殊限定。
请参阅图9，可选的，在沿第一方向X上，中间间隔有一条第二触控走线段42的两条第二触控走线段42同层设置，即，次相邻的两条第二触控走线段42同层设置，以提高第二触控走线段42设置的规律性，便于制备。例如，沿第一方向X，和第一导电层M1同层设置的第二触控走线段42、和第二导电层M2同层设置的第二触控走线段42、和第一导电层M1同层设置的第二触控走线段42依次交替设置。

可以理解的是，在本实施例中，显示面板采用互电容的触控结构，第一触控电极块N1以及第二触控电极块N2中的一者为触控驱动电极，另一者为触控感应电极，第一触控信号线W1和第二触控信号线W2用于分别传输第一触控电极块N1和第二触控电极块N2的电压信号。
在本实施例中，第一触控信号线W1和第二触控信号线W2可以同层设置，例如，第一触控信号线W1和第二触控信号线W2可以同时设于第一触控导电层21或第二触控导电层22。或者，第一触控信号线W1和第二触控信号线W2也可以位于不同层，以增大第一触控信号线W1和第二触控信号线W2的设置空间，便于布线。
可选的，在第一触控信号线W1和第二触控信号线W2不同层设置时，在沿垂直于显示面板的方向上，可以使第一触控信号线W1和第二触控信号线W2至少部分交叠，即减少第一触控信号线W1和第二触控信号线W2的占用空间，以减小显示面板的边框宽度。
可选的，第一触控导电层21包括跨桥部Q，跨桥部Q用于电连接相邻第一触控电极块N1，触控电极20和第二触控导电层22同层设置。由于第一触控电极块N1和第二触控电极块N2通常同层设置，为避免两者相互干扰，在本实施例中，可以在第一触控导电层21设置跨桥部Q连接相邻第一触控电极块N1，而不需要在第二触控导电层22内实现相邻第一触控电极块N1的连接，以避免影响相邻第二触控电极块N2的连接。可选的，第一触控电极块N1和第二触控电极块N2沿第一方向X和第二方向Y阵列排布，跨桥部Q可以连接位于同一列中相邻的第一触控电极块N1，或者，位于同一行中相邻的第一触控电极块N1。
请参阅图2，在一些可选的实施例中，显示面板包括显示区AA以及非显示区NA，非显示区NA包括沿第一方向X设于电路板3两侧的搭接区TA，第一方向X平行于基板1所在平面的方向；搭接部L位于搭接区TA。
需要说明的是，相比于现有技术中，搭接部L设于电路板3朝向触控层2一侧的区域内的形式，本实施例中，搭接部L位于设于电路板3两侧的搭接区TA，搭接部L、第一触控走线段41和第二触控走线段42的设置空间更大，能够有效降低显示面板的边框宽度，实现窄边框。同时，由于搭接部L的设置空间更大，更便于制备、设置至少两个搭接部L实现第一触控走线段41和第二触控走线段42的连接，降低工艺难度。
请参阅图2，在一些可选的实施例中，显示面板还包括信号线8，信号线8和电路板3电连接，在沿垂直于基板1所在平面的方向上，信号线8至少和第一触控走线段41不交叠。
需要说明的是，信号线8通常设于电路板3朝向触控层2一侧的区域，以和电路板3连接，本实施例通过将搭接部L位于设于电路板3两侧的搭接区TA，以避免第一触控走线段41、第二触控走线段42和信号线8之间出现大面积交叠，进而避免触控信号线和信号线8之间出现信号干扰的问题。
可选的，沿远离基板1方向上，显示功能层6包括第一电极层61、发光层62以及第二电极层63，信号线8包括和第二电极层63电连接的电压信号线。
需要说明的是，和第二电极层63电连接的电压信号线通常需要向第二电极层63传输负电压信号，而第一触控走线段41、第二触控走线段42需要传输正电压信号，若第一触控走线段41、第二触控走线段42和电压信号线之间出现交叠，会导致第一触控走线段41、第二触控走线段42的正电压与电压信号线的负电压存在电势差，进而产生电场影响显示面板的可靠性。因而，本实施例中，通过将搭接部L位于设于电路板3两侧的搭接区TA，至少使得第一触控走线段41和信号线8相互避让，以避免信号线8和第一触控走线段41交叠，避免两者之间产生电场，提高了显示面板的可靠性。
请参阅图10，在一些可选的实施例中，第二触控走线段42包括沿第二方向Y延伸的第一部分421，第一部分421通过搭接部L和第一触控走线段41电连接，第二方向Y和第一方向X相交；第一部分421设于搭接部L朝向第一触控走线段41一侧。
需要说明的是，第一部分421设于搭接部L朝向第一触控走线段41一侧，也就是设于搭接部L远离显示面板边缘的一侧，即远离图1中显示面板下边框边缘的一侧，以避免第一部分421距离显示面板的下边缘太近，而导致静电对第一部分421造成损伤，提高显示面板的可靠性。在本实施例中，第一方向X可以为显示面板下边缘的延伸方向，第二方向Y可以垂直于第一方向X。
当然，考虑到实际工艺难度等因素的影响，第一部分421也可以设于搭接部L背离第一触控走线段41的一侧，即第一部分421设于搭接部L靠近显示面板边缘的一侧，并无特殊限定。

可选的，正常搭接部I1与冗余搭接部I2等间距排布，以避免正常搭接部I1与冗余搭接部I2相互干涉，提高正常搭接部I1与冗余搭接部I2设置的规律性，便于制备。
在一些可选的实施例中，显示面板还包括层叠设置的基板1、阵列层5、显示功能层6、封装层7，触控层2以及第一触控走线段41均设于封装层7背离基板1一侧；阵列层5包括至少两层导电层M，第二触控走线段42和导电层M中至少一层同层设置。
需要说明的是，由于触控层2设于封装层7背离基板1一侧。因而，为便于和触控电极20连接，第一触控走线段41也设于封装层7背离基板1一侧，而第二触控走线段42位于封装层7下方的阵列层5内，根据实际需要，第二触控走线段42和导电层M中至少一层同层设置，即第二触控走线段42和同层的导电层M可以通过同一道工艺一同形成，两者的材料相同，以降低生产成本，简化生产流程，便于制备。

需要说明的是，和同一第一触控走线段41所连接的正常搭接部I1、冗余搭接部I2可以和同一过渡连接层H一同连接。或者，也可以使得和第一触控走线段41所连接的正常搭接部I1、冗余搭接部I2中至少一者和一过渡连接层H连接，其他的正常搭接部I1、冗余搭接部I2可以和第二触控走线段42直接连接。
在本实施例中，正常搭接部I1、冗余搭接部I2均包括过孔K以及位于过孔K内的导电部C，导电部C可以和第一触控走线段41或第二触控走线段42的材料相同，考虑到制备流程，导电部C可以和第一触控走线段41采用相同的材料制成。
可选的，根据实际需要，阵列层5还可以设置更多的导电层M，例如，阵列层5还包括设于第三导电层M3背离基板1一侧的第四导电层M4，过渡连接层H或第二触控走线段42可以和第四导电层M4同层设置。
在一些可选的实施例中，在沿第一方向X上，相邻两条第二触控走线段42和不同的导电层M同层设置，第一方向X平行于基板1所在平面的方向。
可以理解的是，通过使得相邻两条第二触控走线段42不同层设置，可以增大第二触控走线段42的设置空间，根据实际需要，第二触控走线段42的线宽也能设置的更大，以保证显示面板的触控走线4的阻抗满足需求。
例如，相邻两条第二触控走线段42中的一条可以和第一导电层M1同层设置，另一条可以和第二导电层M2同层设置。当然，也可以使得第二触控走线段42和第三导电层M3或者其他导电层M同层设置，并无特殊限定。
