请参阅图1,本公开实施例涉及的触控显示装置100例如可以是:平板电脑、手机、电子阅读器、遥控器、个人计算机(personal computer,简称PC)、笔记本电脑、个人数字助理(personal digital assistant,简称PDA)、车载设备、网络电视、可穿戴设备、电视机等。
请参阅图2A和图2B,触控显示装置100中包括触控层组200,触控层组200可以检测到手指的触控位置,从而向触控显示装置100输入触控指令。
本公开的一些实施例提供一种触控层组200。请参阅图2A和图2B,该触控层组200包括触控区AA和周边区BB。
请参阅图2A和图2B,该触控层组200包括:多个第一触控电极21、多个第二触控电极22、多条第一触控走线23、多条第二触控走线24和屏蔽线25。
首先对第一触控电极21和第二触控电极22进行介绍。
在一些实施例中,参见图2A,多个第一触控电极21沿第一方向Y延伸, 多个第二触控电极22沿第二方向X延伸,多个第一触控电极21与多个第二触控电极22之间彼此交叉设置,且相互绝缘。
对于第一触控电极21、第二触控电极22的形状、数量不作限定,每个第一触控电极21和每个第二触控电极22可根据实际需求选择相应的形状、数量,只要能够实现通过检测电容确定触摸点的位置即可。
示例性的,请参阅图2A,第一触控电极21和第二触控电极22均为条状,在此情况下,第一触控电极21和第二触控电极22之间具有交叉区域,即第一触控电极21和第二触控电极22之间具有一定的重合面积。由于第一触控电极21和第二触控电极22之间相互绝缘。示例性的,第一触控电极21和第二触控电极22之间设置绝缘层,并通过绝缘层实现第一触控电极21与第二触控电极22之间的绝缘。因此,在第一触控电极21和第二触控电极22交叉的区域会形成一个电容,当导体(例如手指)触摸到交叉区域时,会改变该区域的原有电容;通过检测电容变化,从而获得触摸点的位置。
在另一些示例中,请参阅图2B,多个第一触控电极21和多个第二触控电极22均位于触控区AA。多个第一触控电极21和多个第二触控电极22在第一方向Y和第二方向X相互交错且同层设置,第一方向Y与第二方向X相交。在一些示例中,第一方向Y与第二方向X垂直。
在一些实施例中,第二触控电极22还包括多个触控子电极221和桥接部22,在第二方向X上相邻的两个触控子电极221通过桥接部22电连接。其中,多个第一触控电极21和多个触控子电极221采用构图工艺(例如包括曝光、显影、刻蚀等步骤)同步形成,同层同材料。其中,第一触控电极21和触控子电极221虽然同层设置,但第一触控电极21和触控子电极221相互绝缘。
其中,请参阅图2B,多个第一触控电极21沿第一方向Y划分为多列,位于同一列的多个第一触控电极21相互耦接,多列第一触控电极21中相邻列的第一触控电极21相互绝缘。示例的,沿第一方向Y,第一列C1中的多个第一触控电极21相互耦接,第一列C1中的多个第一触控电极21和第二列C2中的多个第一触控电极21相互绝缘。其中,每列第一触控电极21例如可以作为一个第一通道,第一通道用于传输第一触控信号。
多个第二触控电极22沿第二方向X划分为多排,位于同一排的多个第二触控电极22相互耦接,多排第二触控电极22中相邻排的第二触控电极22相互绝缘。示例的,沿第二方向X方向,第一排D1中的多个第二触控电极22相互耦接,第一排D1中的多个第二触控电极22和第二排D2中的多个第二触控电极22相互绝缘。其中,每排第二触控电极例如可以作为一个第二通道, 第二通道用于传输第二触控信号。
在一些实施例中,第一触控电极21和第二触控电极22均为网格块状结构。
其中,第一触控电极21可以为Tx(transmit,触控发射电极),第二触控电极22可以为Rx(teceive,触控接收电极),或者,第一触控电极21可以为Rx,第二触控电极22可以为Tx,本公开各实施例对此不作限定。
请参阅图2A和图2B,触控层组200中还包括多条第一触控走线23和多条第二触控走线24,其中,多条第一触控走线23与多个第一触控电极21电连接,且延伸至周边区BB。多条第二触控走线24与多个第二触控电极22电连接,且延伸至周边区BB。其中,一条第一触控走线23与一列第一触控电极21电连接,一条第二触控走线24与一排第二触控电极22电连接。
触控层组200中还包括:屏蔽线25,屏蔽线25位于周边区BB,且位于相邻的第一触控走线23与第二触控走线24之间。
其中,第一触控走线23用于传输第一触控信号,第二触控走线24用于传输第二触控信号,第一触控走线23与第二触控走线24所传输的信号不同。第一触控走线23中的第一触控信号会对第二触控走线24中的第二触控信号产生干扰,同理,第二触控走线24中的第二触控信号会对第一触控走线23中的第一触控信号产生干扰。
本公开通过在相邻的第一触控走线23与第二触控走线24之间设置屏蔽线25,将第一触控走线23与第二触控走线24隔开,以此避免第一触控走线23与第二触控走线24之间相互产生干扰。
其中,屏蔽线25与第一触控走线23之间形成有间隙,以此避免第一触控走线23与屏蔽线25短接。屏蔽线25与第二触控走线24形成有间隙,以此避免第二触控走线24与屏蔽线25短接。
在一种实现方式中,屏蔽线25各处的宽度一致。而触控层组200的周边区BB可以包括多个区域,例如第一扇出区B10、弯折区B20和引出区B30,可参阅图3,图3示出了周边区BB中部分区域的结构。其中,由于不同区域内的布线空间大小不同,因此布线需求不同,当屏蔽线25各处的宽度一致时,无法满足不同区域的布线需求。示例性的,当屏蔽线25设置的较宽时,对于空间较小的区域(如第一扇出区B10),第一扇出区B10内触控线(触控线包括第一触控走线23与第二触控走线24)的宽度需设置的比较小,从而导致屏蔽线25与触控线之间的线宽差异增大,降低了刻蚀均一性,因此,当屏蔽线25各处的宽度一致时,无法满足不同区域的布线需求。并且导致在第一扇 出区B10内触控线与触控线之间以及触控线与屏蔽线25之间的间距也会比较小,容易导致触控线与触控线之间以及触控线与屏蔽线25之间干扰增大,且容易发生耦合。而当屏蔽线25设置的较窄时,对于空间较大的区域(如引出区B30),可以将引出区B30内的触控线的宽度设置的比较大,以降低触控线的电阻。而此时屏蔽线25设置的比较窄,导致屏蔽线25的屏蔽效果不够,使得第一触控走线23与第二触控走线24之间发生干扰。
在本公开的一些实施例提供的触控层组200中,请参阅图4,屏蔽线25包括第一走线段251和第二走线段252,第二走线段252的宽度大于第一走线段251的宽度。
其中,在空间较小的区域内(如第一扇出区B10),可以设置第一走线段251,由于第一走线段251的宽度较小,因此,第一走线段251与第一扇出区B10内的触控线的宽度之间的差异较小,因此可以提高刻蚀的均一性。此外,第一扇出区B10内可以有更大的空间设置触控线,进而可以将触控线的宽度设置的比较大,从而使得屏蔽线25与触控线之间的线宽差异进一步减小,提高了刻蚀均一性。除此之外,将触控线的宽度设置的比较大,还可以降低触控线的电阻。并且在第一扇出区B10内触控线与触控线之间以及触控线与屏蔽线25之间的间距也比较大,降低了触控线与触控线之间以及触控线与屏蔽线25之间干扰,且不容易发生耦合。
在空间较大的区域内,(例如引出区B30内)设置第二走线段252。由于引出区B30的空间较大,因此,不会因为设置第二走线段252而压缩触控线的设置空间。且能够提高屏蔽线25在空间较大的区域内的屏蔽效果。
综上,在周边区BB内设置宽度不同的第一走线段251和第二走线段252,可以满足不同区域的布线需求。
请参阅图4,第二走线段252包括多条子屏蔽线2521,多条子屏蔽线2521同时与第一走线段251电连接,多条子屏蔽线2521沿同一方向(如图4中的Y方向)延伸、且彼此间隔设置,多条子屏蔽线2521所在区域的宽度大于第一走线段251的宽度。例如,如图5所示,在第一扇出区B10内,第一走线段251的宽度为H1,多条子屏蔽线2521所在区域的宽度为H3,其中,H3>H1。
其中,第二走线段252包括多条子屏蔽线2521,相邻两条子屏蔽线2521之间设置有间隙,进而使得相邻两条子屏蔽线2521间隔设置。
屏蔽线25在第二走线段252被分成了多条子屏蔽线2521,子屏蔽线2521与第一触控走线23之间、以及子屏蔽线2521与第二触控走线24之间的线宽 的差异较小,因此可以提高刻蚀的均一性。
此外,不同线宽的走线所产生的静电不同,同时与相邻走线之间的产生的互感电容不同,因此,不同线宽的走线所形成的信号环境不同。因此,在本公开所提供的一些实施例中,靠近子屏蔽线2521的第一触控走线23与远离子屏蔽线2521的第一触控走线23的信号环境的差异较小,进而,靠近子屏蔽线2521的第一触控走线23与远离子屏蔽线2521的第一触控走线23的触控电学的差异较小。同理,靠近子屏蔽线2521的第二触控走线24与远离子屏蔽线2521的第二触控走线24的触控电学的差异较小,进而能够提高触控层组200的触控精度。
在一些实施例中,请参阅图3,周边区BB包括:与触控区AA的第一侧边缘A1连接的第一扇出区B10。第一扇出区B10远离触控区AA的一侧依次设置有弯折区B20、引出区B30和绑定区B40,其中,绑定区B40中设置有接地引脚26,其中,图3中未示出接地引脚26,可参阅图6A和图6B。屏蔽线25可以穿过第一扇出区B10与接地引脚26电连接。其中,接地引脚26接地,因此屏蔽线25可以接地,进而可以将屏蔽线25中积累的静电导出。
在一些实施例中,请参阅图4,第一扇出区B10设置有第一个第二走线段252A,第一个第二走线段252A中的各条子屏蔽线2521沿远离触控区AA的方向延伸。
其中,第一个第二走线段252A中的各条子屏蔽线2521沿远离触控区AA的方向延伸,即第一个第二走线段252A向着靠近接地引脚26(如图6A和图6B所示)的方向延伸,以此使得屏蔽线25逐渐靠近接地引脚26。
在一些示例中,触控区AA指向第一扇出区B10的方向为第一指定方向,且第一指定方向与第一方向Y平行,请参阅图4,箭头F1所指的方向为第一指定方向。第一个第二走线段252A可以大致沿第一指定方向F1延伸。其中,第一个第二走线段252A中包括多条子屏蔽线2521A,第一个第二走线段252A中的各条子屏蔽线2521A均大致沿第一指定方向F1延伸。在本公开的实施例中,“大致沿第一指定方向F1延伸”指的是第一个第二走线段252A中的各条子屏蔽线2521A的延伸方向与第一指定方向F1之间的夹角在5°以内。
在一些实施例中,请参阅图4和图5,第一扇出区B10还设置有第一个第一走线段251A;第一个第一走线段251A沿触控区AA的第一侧边缘A1延伸。第一个第二走线段252A中,各条子屏蔽线2521A靠近触控区AA的端部均与第一个第一走线段251A电连接。
在一些示例中,第一扇出区B10可以作为触控层组200的至少部分边框, 为了实现窄边框,因此,第一扇出区B10在第一方向Y上的尺寸有限。
在第一扇出区B10内设置宽度较小的第一个第一走线段251A,因此,可以减小第一扇出区B10在第一方向Y上的尺寸,进而可以减小触控层组200的边框的尺寸。
在一些示例中,第一侧边缘A1沿第二方向X延伸。
在一些实施例中,请参阅图5,第一个第一走线段251A的宽度H1,为第一个第二走线段252A中任一条子屏蔽线2521A的宽度H2的1.3倍~1.7倍。
在一些示例中,请参阅图5,第一个第一走线段251A的宽度为第一个第一走线段251A在第一方向Y上的尺寸,第一个第二走线段252A中子屏蔽线2521A的宽度H2为第一个第二走线段252A中子屏蔽线2521A在第二方向X上的尺寸,其中,1.3H2≤H1≤1.7H2。
第一个第一走线段251A的宽度H1大于第一个第二走线段252A中任一条子屏蔽线2521A的宽度H2,且1.3H2≤H1≤1.7H2,避免了第一个第一走线段251A与第一个第二走线段252A中任一条子屏蔽线2521A的宽度H2差异过大(例如大于1.7倍),导致第一个第一走线段251A的宽度H1过大,在第一扇出区B10的第一方向Y占用较大的空间,因此,有利于减小第一扇出区B10在第一方向Y上的尺寸。此外,还避免了第一个第一走线段251A的宽度H1与第一个第二走线段252A中任一条子屏蔽线2521A的宽度H2的宽度差异过小(例如小于1.3倍),导致第一个第一走线段251A的宽度H1过小,屏蔽效果降低。
在一些示例中,第一个第一走线段251A的宽度H1,为第一个第二走线段252A中任一条子屏蔽线2521A的宽度H2的1.4倍~1.6倍。
示例性的,第一个第一走线段251A的宽度H1,为第一个第二走线段252A中任一条子屏蔽线2521A的宽度H2的1.5倍。
其中,第一个第二走线段252A中各条子屏蔽线2521A的宽度H2可以相等。
在一些示例中,第一个第一走线段251A的宽度H1的取值范围可以为:25μm≤H1≤31μm。示例性的,第一个第一走线段251A的宽度H1为28μm。
在一些示例中,第一个第二走线段252A中子屏蔽线2521A的宽度H2的取值范围可以为:17μm≤H2≤23μm。示例性的,第一个第二走线段252A中子屏蔽线2521A的宽度H2为20μm。
在一些实施例中,第一个第二走线段252A所在区域的宽度H3为第一个第一走线段251A的宽度H1的3倍~4.5倍。
请参阅图5,第一个第二走线段252A所在区域的宽度H3为第一个第二走线段252A所在区域在第二方向X上的尺寸,其中,3H1≤H3≤4.5H1,避免了第一个第二走线段252A所在区域与第一个第一走线段251A的宽度差异过大(例如大于4.5倍),导致第一个第二走线段252A所在区域的宽度H3过大,在第一扇出区B10的第二方向X上占用较大的空间。此外,还避免了第一个第二走线段252A所在区域的宽度H3与第一个第一走线段251A的宽度H1的宽度差异过小(例如小于3倍),导致第一个第二走线段252A所在区域的宽度H3过小,屏蔽效果降低。
在一些示例中,第一个第二走线段252A所在区域的宽度H3为第一个第一走线段251A的宽度H1的3.5倍~4.1倍。示例性的,第一个第二走线段252A所在区域的宽度H3为第一个第一走线段251A的宽度H1的3.7倍~3.8倍。
在一些示例中,第一个第二走线段252A所在区域的宽度H3的取值范围可以为:102μm≤H3≤110μm。示例性的,第一个第二走线段252A所在区域的宽度H3为106μm。
相邻的两条子屏蔽线2521之间形成有间隙,请参阅图5,在第一个第二走线段252A中,相邻的两条子屏蔽线2521A之间的间隙为H4。在一些示例中,H4的取值范围为:20μm≤H4≤26μm,示例性的,H4为23μm。
以上对屏蔽线25位于第一扇出区B10中的部位进行了介绍,除了屏蔽线25外,第一触控走线23和第二触控走线24也经过第一扇出区B10。以下对第一触控走线23和第二触控走线24位于第一扇出区B10内的部位进行介绍。
在一些实施例中,请参阅图2B,触控区AA大致呈矩形,触控区AA包括第一侧边缘A1、第二侧边缘A2、第三侧边缘A3和第四侧边缘A4,其中,第一侧边缘A1与第二侧边缘A2相对设置,第三侧边缘A3与第四侧边缘A4相对设置,第一侧边缘A1的长度等于第二侧边缘A2的长度,第三侧边缘A3的长度等于第四侧边缘A4的长度,第一侧边缘A1的长度小于第三侧边缘A3的长度。

在第一扇出区B10内,一部分第一触控走线23A位于第一扇出区B10的部分,与多个第二触控走线24位于第一扇出区B10的部分,位于屏蔽线25的两侧。因此,在第一扇出区B10内,屏蔽线25可以避免一部分第一触控走线23A与第二触控走线24相互干扰。

在一些实施例中,第一个第一走线段251A的宽度H1为第一子触控线23A1的宽度H5的1.3倍~1.7倍。
第一子触控线23A1的宽度H5为第一子触控线23A1在第一方向Y上的尺寸。其中,1.3H5≤H1≤1.7H5,避免了第一个第一走线段251A与第一子触控线23A1的宽度差异过大(例如大于1.7倍),导致刻蚀均一性较差。此外,还避免了第一个第一走线段251A的宽度H1与第一子触控线23A1的宽度H5的宽度差异过小(例如小于1.3倍),导致第一个第一走线段251A的宽度H1过小,屏蔽效果降低。

在一些示例中,第一子走线段252B1所在区域的宽度H15的取值范围为:68μm≤H15≤76μm,示例性的,H15=72μm。
在一些示例中,第一个第二走线段252A所在区域的宽度H3为第二个第一走线段251B的宽度H11的6倍~8倍。示例性的,H3=7.57H11。
在一些实施例中,在引出区B30内还设置有第二个第一走线段251B的情况下,参见图7C和图7D,在第一扇出区B10内还设置有第五个第二走线段252E,第五个第二走线段252E沿触控区AA的第一侧边缘A1延伸。第五个第二走线段252E中的多条子屏蔽线2521E均沿第一侧边缘A1延伸。第一子触控线23A1与第三子触控线243分别设置于第五个第二走线段252E的两侧。
第五个第二走线段252E中的多条子屏蔽线2521E的一端与第一个第二走线段252A中的多条子屏蔽线2521A靠近触控区AA的一端一一对应并电连接。
在一些示例中,参见图7C,沿着第一指定方向F1,第五个第二走线段 252E中的多条子屏蔽线2521E的宽度逐渐减小。
在一些示例中,在第五个第二走线段252E中,靠近第一子触控线23A1的子屏蔽线2521E的宽度与第一子触控线23A1的宽度相等,以此使得靠近子屏蔽线2521E的第一触控走线23与远离子屏蔽线2521E的第一触控走线23具有相同的信号环境,以此提高触控层组200的触控性能。
在一些示例中,在第五个第二走线段252E中,靠近第三子触控线243的子屏蔽线2521的宽度与第三子触控线243的宽度相等,以此使得靠近子屏蔽线2521的第二触控走线24与远离子屏蔽线2521的第二触控走线24具有相同的信号环境,以此提高触控层组200的触控性能。
在一些实施例中,参见图6A和图6B,第二走线段252中设置有2~4条子屏蔽线2521。示例性的,第二走线段252中设置有3条子屏蔽线2521。
以上对第一触控走线23、第二触控走线24以及屏蔽线25在各个区域内的结构进行了介绍,以下对第一触控电极21和第二触控电极22进行介绍。
在一些实施例中,请参阅图2B,多个第一触控电极21中的每个第一触控电极21均为一体结构;多个第二触控电极22中的每个第二触控电极22均包括多个触控子电极221以及至少一个桥接部222;第二触控电极22中相邻的两个触控子电极221被一个第一触控电极21间隔开。
请参阅图8A,触控层组200包括:绝缘层201和两个导电层202,绝缘层201位于两个导电层202之间。其中,多个第一触控电极21和多个触控子电极221位于一个导电层202中,多个桥接部222位于另一个导电层202中,一个桥接部222通过绝缘层201上的过孔电连接相邻的两个触控子电极221。
需要说明的是,第一触控电极21为一体结构是指每个第一触控电极21的各个部分均位于同一层,且直接连接在一起。
此外,“同层设置”指的是采用同一成膜工艺形成特定图形的膜层,然后利用同一掩模板通过一次构图工艺形成的层结构。根据特定图形的不同,同一构图工艺可能包括多次曝光、显影或刻蚀工艺,而形成的层结构中的特定图像可以是连续的,也可以是不连续的,这些特定图形还可能处于不同的高度或具有不同的厚度。
在本公开一些实施例中,请参阅图2B,由于每个第一触控电极21为一体结构,且所有的触控子电极221和所有的第一触控电极21同层设置,因此,每个第二触控电极22中由第一触控电极21间隔开的相邻的两个触控子电极221之间由桥接部222通过绝缘层201上的过孔连接在一起,即每个桥接部222均与一个第一触控电极21交叉设置,来实现每个第二触控电极22中各个 触控子电极221之间的电性连接。
在一些实施例中,如图8A所示,第二触控电极22中相邻两个触控子电极221之间通过绝缘层201上的至少两个过孔与桥接部222电连接。
由于被第一触控电极21间隔开的相邻两个触控子电极221之间通过绝缘层201上的至少两个过孔连接,从而使得第一触控电极21和桥接部222之间具有重叠区域,且由于第一触控电极21与桥接部222相互绝缘,因此,在第一触控电极21和桥接部222交叉的区域会形成一个电容,当导体(例如手指)触摸到交叉区域时,会改变该区域的原有电容;通过检测电容变化,从而获得触摸点的位置。
此处,请参阅图8A,除绝缘层201和两个导电层202之外,触控层组200还包括承载面板203,绝缘层201和两个导电层202设置于承载面板203的一侧。第一触控电极21和触控子电极221同层设置,且第一触控电极21与桥接部222位于绝缘层201的两侧,可以是第一触控电极21和触控子电极221设置在绝缘层201上且靠近承载面板203的一侧,桥接部222设置在绝缘层201上且远离承载面板203的一侧;也可以是第一触控电极21和触控子电极221设置在绝缘层201上且远离承载面板203的一侧,桥接部222设置在绝缘层201上且靠近承载面板203的一侧。本公开各实施例对此不作限定。
对于绝缘层201的设置方式不作限定。绝缘层201可以设置为一整层,也可以包括多个数量的绝缘层201。在绝缘层201包括多个数量的情况下,绝缘层201仅设置在第一触控电极21与桥接部222交叉的区域。在绝缘层201为一整层的情况下,示例性的,请参阅图8A,第一触控电极21和触控子电极221在绝缘层201上的正投影在绝缘层201的边界以内。
在第一触控电极21和触控子电极221为金属网格结构时,对于金属网格的金属材料不进行限定。该金属材料可以为金属单质或金属合金等,示例性的,金属材料可以为Ag(银)、Cu(铜)、Al(铝)、或AlNb(铝铌合金)合金中的一种,还可以为多个(至少两个)金属子层层叠设置的金属层,例如包括三个金属子层,位于中间的金属子层的材料为Al(铝),位于中间层的相对两侧的金属子层的材料为Ti(钛),这种结构可记为Ti/Al/Ti。此时,包括第一触控电极21和触控子电极221的导电层202为Ti/Al/Ti结构。
在一些示例中,请参阅图8A,两个导电层202分别为第一导电层2021和第二导电层2022,其中,第二导电层2022位于第一导电层2021背离承载面板203的一侧。其中,第一触控电极21和触控子电极221位于第一导电层2021中,桥接部222位于第二导电层2022中。此时,第一导电层2021为Ti/Al/Ti 结构。本示例中,在第一触控电极21和触控子电极221为金属网格结构时,一方面可以使得整个触控层组200的透光性较好,另一方面,相比于ITO等透明导电材料,由于金属材料的导电率通常较小,可以使得金属材料制成的每个第一触控电极21和第二触控电极22的整体导通性更好。
应当理解到,由于第一触控电极21和触控子电极221同层设置,因此,参考图2B,相邻的第一触控电极21和触控子电极221之间断开。
此外,对于第一触控电极21和触控子电极221为金属网格结构的形状不进行限定。示例性的,如图2B所示,每个第一触控电极21中,除最两端的部分外,其余第一触控电极21的部分由多个菱形构成,且相邻两个菱形的端部直接连接在一起;每个触控子电极221中,除最两端的触控子电极221,其余触控子电极221的形状均为菱形。
需要说明的是,每个第一触控电极21的最两端的部分为第一触控电极21延伸方向的两端,且位于触控区AA的边缘,同样的,最两端的触控子电极221为第二触控电极22延伸方向的两端,且位于触控区AA的边缘。
在此基础上,由于除最两端的第一触控电极21的其余部分由多个菱形直接连接构成,除最两端的触控子电极221,其余触控子电极221的形状均为菱形,因此,最两端的第一触控电极21和触控子电极221的形状可以设置为等腰三角形,且等腰三角形的底边朝向触控层组200的触控区AA的边缘,以使得触控区AA的边缘也设置有第一触控电极21和触控子电极221,这样一来,可以保证触控区AA的边缘无触控盲区。
在一些实施例中,第一走线段251可以为单层线或双层线。在第一走线段251为单层线的情况下,第一走线段251可以位于任一导电层202中。在第一走线段251为双层线的情况下,第一走线段251包括第一子走线和第二子走线,第一子走线和第二子走线分别设置于两个导电层202,第一子走线和第二子走线至少部分地重叠,且第一子走线和第二子走线可以通过位于绝缘层201内的过孔电连接。
在一些实施例中,第二走线段252中的至少一条子屏蔽线2521为单层线或双层线。
在子屏蔽线2521为单层线的情况下,此时,子屏蔽线2521可以位于任意一个导电层202中。例如,子屏蔽线2521可以与第一触控电极21和触控子电极221同层设置,也可以与桥接部222同层设置。示例性的,该单层线为Ti/Al/Ti结构。
在子屏蔽线2521为双层线的情况下,子屏蔽线2521其中一层位于第一 导电层2021中,示例性的,子屏蔽线2521位于第一导电层2021中的部位为Ti/Al/Ti结构。子屏蔽线2521中的另一层可以与桥接部222同层设置,即位于第二导电层2022中,示例性的,子屏蔽线2521位于第二导电层2022中的部位也可以为Ti/Al/Ti结构。此时,一条子屏蔽线2521中位于第一导电层2021中的部位与位于第二导电层2022中的部位,通过绝缘层201中的过孔电连接。
在第二走线段252中的多条子屏蔽线2521均为单层线的情况下:多条子屏蔽线2521位于同一个导电层202中;或者,多条子屏蔽线2521分别位于两个导电层202中,且位于一个导电层202中的至少一条子屏蔽线2521,与位于另一个导电层202中的至少一条子屏蔽线2521在垂直于触控层组200的方向上至少部分地交叠。
其中,在多条子屏蔽线2521分别位于两个导电层202中的情况下,子屏蔽线包括第一子屏蔽线和第二子屏蔽线,其中,至少一条第一子屏蔽线与至少一条第二子屏蔽线至少部分地交叠。示例性的,一条第一子屏蔽线与一条第二子屏蔽线完全重叠,以此可以减小子屏蔽线所占的空间,增大触控线所占的空间,进而可以增大触控线的宽度,降低触控线与屏蔽线25之间的宽度差异,提高刻蚀的均一性。
在一些实施例中,请参阅图8B,触控层组200包括:多条第一类触控走线204和多条第二类触控走线205,多条第一类触控走线204与多条第二类触控走线205分别设置于两个导电层202。其中,第一类触控走线204和第二类触控走线205均为单层线。
在一些示例中,请参阅图8B,两个导电层202分别为第一导电层2021和第二导电层2022。其中,第一类触控走线204位于第一导电层2021中,第二类触控走线205位于第二导电层2022中。其中,第二导电层2022位于第一导电层2021背离承载面板203的一侧。
第一类触控走线204与第二类触控走线205在垂直于触控层组200的方向上至少部分地交叠。进而可以减少第一类触控走线204和第二类触控走线205所占的面积。此外,可以将第一类触控走线204的宽度和第二类触控走线205的宽度设计的更宽,以此减小屏蔽线25与第一类触控走线204的宽度之间的宽度差异以及屏蔽线25与第二类触控走线205之间的宽度差异,进而能够提高刻蚀的均一性。
在一些示例中,一条第一类触控走线204与一条第二类触控走线205可以完全重叠,或者部分重叠。
其中,多条第一类触控走线204中包括部分第一触控走线23和部分第二 触控走线24,多条第二类触控走线205中包括另一部分第一触控走线23和另一部分第二触控走线24。
其中,多条第一触控走线23分别设置于两个导电层202中,第一触控走线23为单层线,因此,任意两条第一触控走线23分别连接于不同的第一引脚27(如图6A和图6B所示)。
多条第二触控走线24分别设置于两个导电层202中,第二触控走线24为单层线,因此,任意两条第二触控走线24分别连接于不同的第二引脚28。
在其他的一些示例中,请参阅图8C,第一触控走线23为双层线。当然,第二触控走线24也可以为双层线。
在一些实施例中,请参阅图8A~图8C,触控层组200还包括保护层206,其中,保护层206位于两个导电层202远离承载面板203的一侧,此时,两个导电层202以及绝缘层201位于保护层206和承载面板203之间,其中,保护层206可以对两个导电层202进行保护,避免导电层202被划伤,影响触控功能。
在一些实施例中,请参阅图9和图10,触控显示装置100还包括显示基板300,触控层组200位于显示基板300的显示面上。此时,显示基板300即为上述承载面板203。
其中,请参阅图11,显示基板300包括显示区SS。显示区SS内设置有多个亚像素P,亚像素P是显示基板300进行画面显示的最小单元,每个亚像素P可显示一种单一的颜色,例如红色(R)、绿色(G)或蓝色(B)。显示基板300内设置有很多的红色子像素、绿色子像素和蓝色子像素,调节不同颜色子像素的亮度(灰阶),通过颜色组合和叠加可以实现多种颜色的显示,从而实现显示基板300的全彩化显示。
触控层组200的触控区AA的边缘与显示区SS的边缘大致重合。
如图9所示,在触控显示装置100为液晶触控显示装置的情况下,显示基板300为液晶显示基板300A。液晶显示基板300A的主要结构包括阵列基板31、对盒基板32以及设置在阵列基板31和对盒基板32之间的液晶层33。

如图10所示,在触控显示装置100为电致发光触控显示装置的情况下,显示基板300为电致发光显示基板300B。例如OLED显示基板具有轻薄、可绕性、色彩绚丽、对比度高、响应速率快等优势,是目前主流显示基板之一。在触控显示基板为电致发光显示基板的情况下,显示基板300为柔性显示基板,此时,触控显示装置可以被制作为柔性显示装置。
如图10所示,电致发光显示基板300B可以包括显示用基板36和用于封装显示用基板36的封装层37。此处,封装层37可以为封装薄膜,也可以为封装基板。
如图10所示,上述亚像素包括设置在第三衬底360上的驱动电路和发光器件,驱动电路包括多个薄膜晶体管311。发光器件包括阳极361、发光功能层362以及阴极363,阳极361和多个薄膜晶体管311中作为驱动晶体管的薄膜晶体管311的漏极电连接。电致发光显示基板300B还包括像素界定层364,像素界定层364包括多个开口区,发光功能层362设置在一个开口区中。在一些实施例中,发光功能层362包括发光层。在另一些实施例中,发光功能层362除包括发光层外,还包括电子传输层(election transporting layer,简称 ETL)、电子注入层(election injection layer,简称EIL)、空穴传输层(hole transporting layer,简称HTL)以及空穴注入层(hole injection layer,简称HIL)中的一层或多层。
如图10所示,发光功能层362还包括设置在驱动电路和阳极361之间的平坦层365。
参考图10可知,第一触控电极21和触控子电极221设置在电致发光显示基板300B的出光面,此时,桥接部222可以设置在第一触控电极21靠近或远离电致发光显示基板300B的一侧。在桥接部222设置在第一触控电极21靠近显示用基板36一侧的情况下,第一触控电极21和触控子电极221整体与桥接部222之间具有绝缘层201。
在一些实施例中,如图10所示,显示基板300还包括设置在封装层37上的缓冲层38,以此防止在形成第一触控电极21和触控子电极221时,导致封装层37被损伤划坏。
在一些实施例中,电致发光显示基板300B包括依次设置于第三衬底360上的有源膜层366、第一栅金属层Gate1、第二栅金属层Gate2、第一源漏金属层SD1和第二源漏金属层SD2。其中,有源膜层366和第一栅金属层Gate1用于形成驱动电路中的部分薄膜晶体管311。有源膜层366和第二栅金属层Gate2用于形成驱动电路中的其余部分晶体管311,而第一栅金属层Gate1和第二栅金属层Gate2用于形成驱动电路中的电容。第一源漏金属层SD和第二源漏金属层SD2中包括多条向驱动电路传输信号的信号线,例如数据线、初始化信号线、电源信号线等,在此不一一列举。
基于显示基板300为电致发光显示基板300B的实施例,在一些实施例中,在触控层组200包括位于第一扇出区B10的第一个第二走线段252A,和位于引出区B30的第二个第二走线段252B的情况下:显示基板300对应弯折区B20的部位设置有多个跳线;第一个第二走线段252A中的一个子屏蔽线2521A通过至少一个跳线电连接至第二个第二走线段252B中的一个子屏蔽线2521B。
首先需要说明的是,在一些示例中,触控层组200包括第一扇出区B10、弯折区B20、引出区B30和绑定区B40,而触控显示装置100包括触控层组200,因此,触控显示装置100也包括第一扇出区B10、弯折区B20、引出区B30和绑定区B40。而触控显示装置100还包括显示基板300,因此,显示基板300也包括第一扇出区B10、弯折区B20、引出区B30和绑定区B40,且显示基板300中的第一扇出区B10与触控层组200中的第一扇出区B10为同 一区域,显示基板300中的弯折区B20与触控层组200中的弯折区B20为同一区域,显示基板300中的引出区B30与触控层组200中的引出区B30为同一区域,显示基板300中的绑定区B40与触控层组200中的绑定区B40为同一区域。
在一些示例中,第二个第二走线段252B包括第一子走线段252B1和第二子走线段252B2,子屏蔽线2521B包括子屏蔽线2521B1和子屏蔽线2521B2,此时,多个跳线中的至少一个跳线的两端分别与子屏蔽线2521A和子屏蔽线2521B2电连接。
其中,显示基板300的弯折区B20可以进行弯折,弯折区B20的部分区域、引出区B30以及绑定区B40可以弯折至显示基板300的背面,以此减小了显示基板300边框的宽度,满足显示基板300中“小下巴”的需求。
其中,显示基板300对应弯折区B20的部位的抗弯折能力较强,因此,通过位于显示基板300内跳线连接子屏蔽线2521A和子屏蔽线2521B,可以减少走线断裂,导致屏蔽线25失效。
上述用于连接子屏蔽线2521A和子屏蔽线2521B的跳线定义为第一跳线。除此之外,显示基板300对应弯折区B20的部位还设置有多个第二跳线,第一触控走线23位于第一扇出区B10内的部位与第一触控走线23位于引出区B30内的部位通过第二跳线电连接。
显示基板300对应弯折区B20的部位还设置有多个第三跳线,第二触控走线24位于第一扇出区B10内的部位和第二触控走线24位于引出区B30内的部位通过第三跳线电连接。
其中,跳线可以设置于第一栅金属层Gate1、第二栅金属层Gate2、第一源漏金属层SD1和第二源漏金属层SD2中的至少一层。
在其他的一些实施例中,触控层组对应弯折区B20的部位设置有第六个第二走线段,第六个第二走线段中的多条子屏蔽线沿远离触控区AA的方向延伸,在一些示例中,第六个第二走线段沿第一指定方向F1延伸。第六个第二走线段中的多条子屏蔽线靠近触控区AA的端部与第一个第二走线段252A中多个子屏蔽线2521A远离触控区AA的一端一一对应并电连接。第六个第二走线段中的多条子屏蔽线远离触控区AA的端部与第二个第二走线段252B中的多条子屏蔽线2521B靠近触控区AA的一端一一对应并电连接。
以上所述,仅为本公开的具体实施方式,但本公开的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本公开揭露的技术范围内,想到变化或替换,都应涵盖在本公开的保护范围之内。因此,本公开的 保护范围应以所述权利要求的保护范围为准。
