触控技术近些年发展迅猛，目前已有多种触控技术投入量产。对于现有的触控显示面板，根据触控传感器（Touch Sensor）设置位置的不同，可分为触控传感器覆盖于液晶盒上式（On Cell）、触控传感器内嵌在液晶盒内式（In Cell）、以及触控传感器外挂于显示面板式（Out Cell）。
而随着科技之进步，人们对电子产品质量要求越来越高，在激烈的竞争之下，电子制造商们纷纷以美观、轻、薄、窄为目标，同时又希望其液晶屏幕能越大越好。全屏幕显示屏的出现，使之成为一种风尚，加上Iphone X产品的量产，使得全屏幕成为各家显示工厂追求的终极技术解决方案。
为了达到窄边框的效果，目前触摸屏采用的是边缘走线，但当走线的最小线宽达到工艺的极限时，也就无法继续实现更窄的边框。

实施例2
请参阅图1、图4和图5，本发明又提供另一种柔性显示面板，其表面定义有显示区、结合区和边框区，柔性显示面板包括柔性基板1、保护层2、半导体层3、发光层4和触控层5。
显示区的柔性基板1上设有栅极引线21、地线22、触控感应接收电极引线23、数据引线24、触控感应发送电极引线25以及显示区衬垫80；边框区的保护层2的侧部设置有第一通孔261、第二通孔262、第三通孔263以及第四通孔264，栅极引线21通过第一通孔261与半导体层3中的栅极电性连接，触控感应接收电极引线23通过第二通孔262与触控层5中的触控感应接收电极电性连接，数据引线24通过第三通孔263与半导体层3中的数据线电性连接，触控感应发送电极引线25通过第四通孔264与触控层5中的触控感应发送电极电性连接。
数据引线24和触控感应发送电极引线25从远离结合区端引入连接至显示区衬垫80。
实施例3
请参阅图6，本发明还提供了一种柔性显示面板的制备方法，包括具体以下步骤：
步骤S11：在显示区的柔性基板1上制作栅极引线11、地线12、触控感应接收电极引线13和显示区衬垫80；
步骤S12：在柔性基板1上制作一层保护层2，在边框区的保护层2边缘位置制作第一通孔161和第二通孔162；
其中，保护层2为绝缘层，保护柔性基板1上所有的走线；
步骤S13：制作半导体层3和结合区衬垫70，同时制作数据引线14，并将栅极引线11通过第一通孔161与半导体层3中的栅极电性连接；
其中，栅极引线11、地线12、触控感应接收电极引线13在结合区连接至结合区衬垫70；
步骤S14：制作发光层4；
步骤S15：制作触控层5和触控感应发送电极引线15，并将触控感应接收电极引线13通过第二通孔162与触控层5中的触控感应接收电极电性连接；
其中，数据引线14和触控感应发送电极引线15从靠近结合区端引入连接至显示区衬垫80；
步骤S16：制作偏光片、保护膜和边框，实现触控显示模组。
本实施例可以实现窄边框设计，并且也能实现显示结合区和触控结合区分别独立开来，便于独立设计集成电路；但也会存在引线互相交叉，虽然不在同层上，并且中间又绝缘层保护，但由于引线布局起来比较凌乱，且互相间又信号干扰，会给集成电路带来额外负担，并且结合区的引线会占用一定空间，导致结合区实现边框相对较宽，为了改进这种情况，现提供另一实施例。
实施例4
请参阅图7，本发明又提供了另一种柔性显示面板的制备方法，包括具体以下步骤：
步骤S21：在显示区的柔性基板1上制作栅极引线21、地线22、触控感应接收电极引线23、数据引线24、触控感应发送电极引线25和显示区衬垫80；
其中，数据引线24和触控感应发送电极引线25从远离结合区端引入；
步骤S22：在柔性基板1上制作一层保护层2，在边框区的保护层2边缘位置制作第一通孔261、第二通孔262、第三通孔263和第四通孔264；
其中，保护层2为绝缘层，保护柔性基板1上所有的走线；
步骤S23：制作半导体层3和结合区衬垫70，并将栅极引线21通过第一通孔261与半导体层3中的栅极电性连接，将数据引线24通过第三通孔263与半导体层3中的数据线电性连接；
步骤S24：制作发光层4；
步骤S25：制作触控层5，并将触控感应接收电极引线23通过第二通孔262与触控层5中的触控感应接收电极电性连接，同将触控感应发送电极引线25通过第四通孔264与触控层5中触控感应发送电极电性连接；
其中，数据引线14和触控感应发送电极引线15从远离结合区端引入连接至显示区衬垫80；
步骤S26：制作偏光片、保护膜和边框，实现触控显示模组。
实施例4相比于实施例3优势在于通过数据引线和触控感应发送电极引线引入位置调整，可以使得所有引线都隐藏于半导体层下方而不可视，从而减少引线在结合区占有的空间，这样在结合区端仅有衬垫，可以根据结合区衬垫大小和特殊线路需求，调整结合区的边框宽度，从而大大减少结合区的宽度，但是这一实施方式有一个限制，集成电路的类型只能是触控与显示驱动器集成电路。
上述实施例中的所有引线在显示区内部皆使用透明的电路走线，在结合区可使用透明的电路走线或是不透明的金属走线。
本发明的触控传感器的制作模式既可以是On cell模式也可以是In cell模式，均属于本发明的窄边框技术，制作步骤中的触控层的制作可根据实际的On cell或者In cell模式进行调整。
本发明的有益效果在于，改变传统走线位置，采用了一种隐藏式走线设计，走线与显示区同位置设计，这样就不会占用额外空间，减少无显示区域，有效缩小了面板边缘走线宽度，甚至可以实现零边缘宽度，提升屏占比，减少了同尺寸下使用的原材料；进一步的，将触控和显示集成在一起实现窄边框方案，结合区也可以实现极窄边框。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
