在一实施例中,驱动电极506、接收电极508和第一桥接线510分布于第一导电层501,第二桥接线511分布于第二导电层503。在另一实施例中,第一桥接线510分布于第一导电层501,驱动电极506、接收电极508和第二桥接线511分布于第一导电层501。
当用户手指触摸显示面板的可触控区域时,触控点处绝缘交叉设置的驱动电极组507和接收电极组509的互电容发生改变。驱动电路逐条扫描驱动电极组507和接收电极组509中的驱动电极组507,每扫描一条驱动电极组507的同时读取各条驱动电极组507和接收电极组509中探测电极组的信号,通过一轮扫描,便可以确定出触摸点的坐标,基于触摸点的坐标进行触摸操作对应的内容响应。
触控层500还包括驱动触控走线512和接收触控走线513,其中驱动触控走线512可与驱动电极组507连接,接收触控走线513可与接收电极组509连接。进一步地,触控层500还包括第一触控走线514和第二触控走线515,其中,第一触控走线514为接收触控走线513,即与接收电极508连接,用于传输驱动电极506和接收电极508间的互感电容变化信号。第二触控走线515用于加载屏蔽信号。第二触控走线515位于第一触控走线514远离显示区110的一侧。进一步地,触控层500还包括接地线516,接地线516位于第二触控走线515远离显示区110的一侧。
进一步地,第一触控走线514为所有接收触控走线513中最外侧的一条线,即在平行于衬底基板100方向上距离显示区110最远的一条接收触控走线513。第二触控走线515位于第一触控走线514和接地线516之间,用于加载屏蔽信号,以防止第一触控走线514和接地线516之间发生信号干扰。具体地,第二触控走线515可加载触控驱动信号。
第一触控走线514和第二触控走线515均包括沿第一方向X延伸的第一段514a或515a,第一触控走线514和第二触控走线515的第一段514a或515a均位于第二外围区122。在本公开一些实施例中,第一触控走线514的第一段514a和第二触控走线515的第一段515a在平行于衬底基板100方向上的距离不大于20μm。
如图4和图7所示,第一触控走线514和第二触控走线515的第一段514a或515a均包括相互连接的第一子段14a1或15a1和第二子段14a2或15a2,第一触控走线514的第一子段14a1、第二子段14a2与衬底基板100之间的距离不等,第二触控走线515的第一子段15a1、第二子段15a2与衬底基板100之间的距离不等。即,第一触控走线514的第一子段14a1和第二子段14a2相对于衬底基板100具有高度差,第二触控走线515的第一子段15a1和第二子段15a2相对于衬底基板100具有高度差。
具体地,第一触控走线514和第二触控走线515的第一子段14a1或15a1在衬底基板100上的正投影均不与第一有机层301在衬底基板100上的正投影重叠;第一触控走线514和第二触控走线515的第二子段14a2或15a2在衬底基板100上的正投影均位于第一有机层301的第二区域015在衬底基板100上的正投影之内。
第一有机层301还包括凸块单元016,凸块单元016在衬底基板100上的正投影至少部分位于第一触控走线514的第一子段14a1或15a1和第二触控走线515的第一子段14a1或15a1两者在衬底基板100上的正投影之间。进一步地,凸块单元016可位于第一子段14a1或15a1和第二子段14a2或15a2的交界处。如此,可将位于高度差位置处的第一触控走线514和第二触控走线515的第一子段14a1或15a1予以间隔,从而降低两者发生短路的风险。
凸块单元016的设置方式可以有多种,下面将结合不同的实施例来举例说明凸块单元016的设置方式。
如图7、图8、图9、图11和图12所示,图12为图11中凸块单元016在第三方向Y上的截面图,在本公开一些实施例中,凸块单元016包括第一凸块161;第一有机层301的第二区域015具有沿第二方向X0延伸的第一边缘015b,第二方向X0与第一方向X不平行。第二方向X0与第一方向X的夹角可以大于0°,小于等于90°。第一有机层301的第二区域015的第一边缘015b的至少部分沿第一方向X朝靠近第一子段14a1或15a1方向凸起形成至少一个第一凸块161。第一凸块161的数量可以为一个或多个。当第一凸块161的数量为多个时,多个第一凸块161可沿第三方向Y依次排列,第三方向Y与第一方向X大致垂直。
第一凸块161在衬底基板100上的正投影可以有多种,其可以是长方形、椭圆形或多边形等,具体可不做限定。优选地,第一凸块161在衬底基板100上的正投影大致为长方形。进一步地,第一凸块161在垂直于衬底基板100方向上的截面可以为长方形、正梯形、倒梯形或顶端为弧形、尖角等的不规则形状等。
第一凸块161的大小也可以有多种,举例而言,第一凸块161在第一方向X上的尺寸不小于35μm。即第一有机层301的第二区域015的第一边缘015b沿第一方向X朝靠近第一子段14a1或15a1方向凸起的长度L0不小于35μm。在平行于衬底基板100方向上,第一凸块161的边缘与第一触控走线514或第二触控走线515的最短距离h不小于4μm。如图7所示,当凸块单元016只包含一个第一凸块161时,该第一凸块161与第一触控走线514之间的距离不小于4μm,且该第一凸块161与第二触控走线515之间的距离也不小于4μm。如图11所示,当凸块单元016包括多个第一凸块161时,最靠近第一触控走线514的第一凸块161与第一触控走线514之间的距离不小于4μm,最靠近第二触控走线515的第一凸块161与第二触控走线515之间的距离不小于4μm。在该实施例中,对第一凸块161的尺寸限制是为了确保第一触控走线514和第二触控走线515在刻蚀时短路(short)现象发生路径的延长效果,以进一步降低对应位置处发生短路的风险。
如图13至图15所示,图14为图15中凸块单元016在第三方向Y上的截面图,在本公开另一些实施例中,凸块单元016还包括至少一个第二凸块162,第二凸块162设于第一凸块161或第一有机层301的第二区域015远离衬底基板100的一侧,至少部分第二凸块162在衬底基板100上的正投影位于第一凸块161在衬底基板100上的正投影之内。在该实施例中,多个第二凸块162可全部设于第一凸块161远离衬底基板100的一侧,且这些第二凸块162在衬底基板100上的正投影位于第一凸块161在衬底基板100上的正投影之内。在垂直于衬底基板100方向上,一个第一凸块161可对应设置一个或多个第二凸块162。此外,如图15所示,多个第二凸块162中,部分第二凸块162可设于第一凸块161远离衬底基板100的一侧,且该部分第二凸块162在衬底基板100上的正投影位于第一凸块161在衬底基板100上的正投影之内,剩余第二凸块162可设于第一有机层301的第二区域015远离衬底基板100的一侧,且该部分第二凸块162在衬底基板100上的正投影位于第一有机层301的第二区域015在衬底基板100上的正投影之内。
第二凸块162在衬底基板100上的正投影可以为圆形、椭圆形或多边形等,第二凸块162在垂直于衬底基板100方向上的截面可以为长方形、正梯形、倒梯形或其他多边形等。进一步地,如图14所示,在垂直于衬底基板100方向上,第一凸块161和第二凸块162的高度之和为1.5μm-2.5μm,在该范围内,不仅可确保第一触控走线514和第二触控走线515在刻蚀时短路(short)现象发生路径的延长效果,降低对应位置处发生短路的风险,同时也不影响其他膜层的制备,保证其他膜层的正常制作。
如图16至图18所示,图17为图16中C部分放大图,图18为图16中凸块单元016在第三方向Y上的截面图。在本公开又一些实施例中,凸块单元016包括第一凸块单元163,第一凸块单元163包括多个第三凸块164,多个第三凸块164阵列排布于第一触控走线514的第一段514a和第二触控走线515的第一段515a之间;多个第三凸块164在衬底基板100上的正投影与第一有机层301的第二区域015不重叠,且多个第三凸块164在衬底基板100上的正投影位于第一触控走线514的第一子段14a1和第二触控走线515的第一子段15a1之间。
第三凸块164在衬底基板100上的正投影可以为圆形、椭圆形或多边形等,第三凸块164在垂直于衬底基板100方向上的截面可以为长方形、正梯形、倒梯形或其他多边形等。进一步地,如图18所示,在垂直于衬底基板100方向上,第三凸块164的高度为1.5μm-2.5μm。同上述实施例,在该范围内,不仅可确保第一触控走线514和第二触控走线515在刻蚀时短路(short)现象发生路径的延长效果,降低对应位置处发生短路的风险,同时也不影响其他膜层的制备,保证其他膜层的正常制作。
凸块单元016还包括第二凸块单元165,第二凸块单元165位于第一凸块单元163在第一方向X上的一侧,第二凸块单元165包括多个第四凸块166;多个第四凸块166阵列排布于第一触控走线514的第一段514a和第二触控走线515的第一段515a之间;多个第四凸块166在衬底基板100上的正投影位于第一有机层301的第二区域015在衬底基板100上的正投影之内。
第四凸块166在衬底基板100上的正投影可以为圆形、椭圆形或多边形等,第四凸块166在垂直于衬底基板100方向上的截面可以为长方形、正梯形、倒梯形或其他多边形等。进一步地,在垂直于衬底基板100方向上,第四凸块166和第一有机层301第二区域015的高度之和为1.5μm-2.5μm。
如图17所示,第一凸块单元163在第一方向X上的尺寸L1不小于35μm,且凸块单元016在第一方向X上的尺寸L2不大于200μm。该数值设置不仅可确保第一触控走线514和第二触控走线515在刻蚀时短路(short)现象发生路径的延长效果,降低对应位置处发生短路的风险,同时也不影响其他膜层的制备,保证其他膜层的正常制作。进一步地,第一凸块单元163中最靠近第一有机层301第二区域015的第三凸块164与第一有机层301的第二区域015之间的距离不大于5μm,第一凸块单元163中最远离第一有机层301第二区域015的第三凸块164的外侧边缘与第一有机层301的第二区域015之间的距离不小于35μm,其中,第三凸块164的外侧边缘是指该第三凸块164远离第一有机层301第二区域015的边缘。
在本公开中,第一有机层301中所包括的各个结构,如像素定义区011、第一区域014、第二区域015、隔离柱013和凸块单元016等可通过一道光刻工艺形成。例如,可于第一电极层302远离衬底基板100的一侧形成第一有机材料层,随后采用半透膜掩膜板对该第一有机材料层进行图案化,以形成第一有机层301。
在本公开中,第一触控走线514和第二触控走线515可以是双层走线,也可以是单层走线,且第一触控走线514和第二触控走线515的不同走线段单双层设置方式可不同。
如图4、图8、图10和图21所示,在本公开一些实施例中,第一触控走线514分布于第一导电层501和第二导电层503两层导电层中,第一触控走线514中分布于不同导电层中的走线在衬底基板100上的正投影至少部分重叠,且分布于不同导电层中的走线通过绝缘层502中的至少一个第一过孔514c连接。第二触控走线515分布于第一导电层501和第二导电层503两层导电层中,第二触控走线515中分布于不同导电层中的走线在衬底基板100上的正投影至少部分重叠,且分布于不同导电层中的走线通过绝缘层502中的至少一个第二过孔515c连接。即,第一触控走线514和第二触控走线515为双层走线。其中,图21为分布于不同导电层中的走线过孔连接示意图。
进一步地,第一触控走线514和第二触控走线515均还包括沿第三方向Y延伸且与第一段514a或515a连接的第二段514b或515b,第三方向Y与第一方向X不平行。至少一个第一过孔514c在衬底基板100上的正投影位于第一触控走线514的第二段514b在衬底基板100上的正投影之内。至少一个第二过孔515c在衬底基板100上的正投影位于第二触控走线515的第二段515b在衬底基板100上的正投影之内。第一触控走线514的第二段514b的线宽大于第一触控走线514第一段514a的线宽。第二触控走线515第二段515b的线宽大于第二触控走线515第一段515a的线宽。在该实施例中,第三方向Y与第一方向X的夹角可以为45°-90°。如在一实施例中,第三方向Y与第一方向X的夹角为45°,在另一实施例中,第三方向Y与第一方向X大致垂直。
如图19、图20和图21所示,图20是图19中E部分放大图,在本公开另一些实施例中,第一触控走线514的第一段514a分布于第一导电层501或第二导电层503;第二触控走线515的第一段515a分布于第一导电层501或第二导电层503;且第一触控走线514的第一段514a和第二触控走线515的第一段515a不同层设置。如,第一触控走线514的第一段514a分布于第一导电层501,则第二触控走线515的第一段515a分布于第二导电层503;又如,第一触控走线514的第一段514a分布于第二导电层503,第二触控走线515的第一段515a分布于第一导电层501。在该实施例中,由于第一触控走线514的第一段514a和第二触控走线515的第一段515a分布于不同导电层,因此,可以缩短两者在平行于衬底基板100方向上的间距,有助于实现显示面板的窄边框设计。
在该类实施例中,第一触控走线514和第二触控走线515也可均还包括沿第三方向Y延伸且与第一段514a或515a连接的第二段514b或515b,第三方向Y与第一方向X不平行。其中,第一触控走线514的第二段514b和第二触控走线515的第二段515b可以为双层走线,即,第一触控走线514的第二段514b分布于第一导电层501和第二导电层503两层导电层中,第一触控走线514中分布于不同导电层中的走线在衬底基板100上的正投影至少部分重叠,且分布于不同导电层中的走线通过绝缘层502中的至少一个第一过孔514c连接。第二触控走线515的第二段515b分布于第一导电层501和第二导电层503两层导电层中,第二触控走线515中分布于不同导电层中的走线在衬底基板100上的正投影至少部分重叠,且分布于不同导电层中的走线通过绝缘层502中的至少一个第二过孔515c连接。至少一个第一过孔514c在衬底基板100上的正投影位于第一触控走线514的第二段514b在衬底基板100上的正投影之内。至少一个第二过孔515c在衬底基板100上的正投影位于第二触控走线515的第二段515b在衬底基板100上的正投影之内。第一触控走线514的第二段514b的线宽大于第一触控走线514第一段514a的线宽。第二触控走线515第二段515b的线宽大于第二触控走线515第一段515a的线宽。如此,第一触控走线514和第二触控走线515的第一段514a或515a单层走线设计有助于实现显示面板更窄边框设计,而第一触控走线514和第二触控走线515的第二段514b或515b的双层走线设计有助于降低电阻,提升传输信号的稳定性和均一性。
如图7所示,在本公开一些实施例中,触控层500所包括的接地线516可以为单层走线也可以为双层走线,具体可不做限定。接地线516包括沿第一方向X延伸的第一主段516a和第二主段516b,以及连接于第一主段516a和第二主段516b之间弯折段516c,第一主段516a在衬底基板100上的正投影与第一有机层301的第二区域015在衬底基板100上的正投影不重叠,第二主段516b在衬底基板100上的正投影位于第一有机层301的第二区域015在衬底基板100上的正投影之内。接地线516的弯折段516c与第二触控线的第一段515a之间的最大距离,大于接地线516的第一主段516a/第二主段516b与第二触控线的第一段515a之间的最大距离。即,接地线516的弯折段516c与第二触控线的第一段515a之间的最大距离大于第一主段516a与第二触控线的第一段515a之间的距离,且大于第二主段516b与第二触控线的第一段515a之间的距离。如此,增大了接地线516与第二触控走线515在该位置处的距离,有助于降低接地线516与第二触控走线515之间发生短路的风险。
其中,弯折段516c在衬底基板100上的正投影部分与第一有机层301的第二区域015在衬底基板100上的正投影不重叠,部分位于第一有机层301的第二区域015在衬底基板100上的正投影之内。弯折段516c在衬底基板100上的正投影与第一有机层301的第二区域015的边缘在衬底基板100上的正投影相交形成第一夹角α,0°<α<90°。即第一有机层301第二区域015的边缘与弯折段516c非垂直交叉,如此,可延长刻蚀金属残留路径,进一步降低第二触控走线515和接地线516之间发生短路的风险。
在一实施例中,弯折段516c包括依次连接的第一子弯折段16c1、第二子弯折段16c2和第三子弯折段16c3,第二子弯折段16c1沿第一方向X延伸,第一子弯折段16c1连接第一主段516a和第二子弯折段16c2,第三子弯折段16c3连接第二主段516b和第二子弯折段16c2;第一子弯折段16c1在衬底基板100上的正投影与第一有机层301的第二区域015在衬底基板100上的正投影不重叠,第三子弯折段16c3在衬底基板100上的正投影位于第一有机层301的第二区域015在衬底基板100上的正投影之内。进一步地,第二子弯折段16c2在衬底基板100上的正投影与第一有机层301的第二区域015的边缘在衬底基板100上的正投影相交形成第一夹角α。
如图19和图20所示,在本公开一些实施例中,第一有机层301也可不包含凸块单元016。在该类实施例中,第一触控走线514的第一段514a分布于第一导电层501或第二导电层503,第二触控走线515的第一段515a分布于第一导电层501或第二导电层503,且第一触控走线514的第一段514a和第二触控走线515的第一段515a不同层设置。
在该类实施例中,第一触控走线514和第二触控走线515均还包括沿第三方向Y延伸且与第一段514a或515a连接的第二段514b或515b,第三方向Y与第一方向X不平行;第一触控走线514的第二段514b分布于第一导电层501和第二导电层503两层导电层中,第一触控走线514中分布于不同导电层中的走线在衬底基板100上的正投影至少部分重叠,且分布于不同导电层中的走线通过绝缘层502中的至少一个第一过孔514c连接;第二触控走线515的第二段515b分布于第一导电层501和第二导电层503两层导电层中,第二触控走线515中分布于不同导电层中的走线在衬底基板100上的正投影至少部分重叠,且分布于不同导电层中的走线通过绝缘层502中的至少一个第二过孔515c连接;至少一个第一过孔514c在衬底基板100上的正投影位于第一触控走线514的第二段514b在衬底基板100上的正投影之内;至少一个第二过孔515c在衬底基板100上的正投影位于第二触控走线515的第二段515b在衬底基板100上的正投影之内。
此外,在该类实施例中,第一有机层301也可包括凸块单元016,凸块单元016的设置方式可参照上述任一实施例,在此不详细描述。
