具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施例，对本申请进行进一步详细描述。应理解，此处所描述的具体实施例仅被配置为解释本申请，并不被配置为限定本申请。对于本领域技术人员来说，本申请可以在不需要这些具体细节中的一些细节的情况下实施。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。
随着终端设备的发展，产生了对触控显示面板的更窄边框的要求。相关技术的触控显示面板中，采用缩小引线区多条电极引线的线宽或线间距、以及采用透明导电材料制作多条电极引线的方式来缩小边框宽度，然而上述方式会提高电极通道的阻抗，降低产品性能及生产良率。
本申请实施例提供一种触摸感应装置，图1、图2是本申请一种实施例提供的触摸感应装置的俯视示意图、截面示意图，其中图1中AA线示出图2的截面示意图的截取位置。触摸感应装置100具有触摸感应区TS以及位于触摸感应区TS外周的引线区LA。
触摸感应装置100可以包括第一基板110、多个图案化电极120以及两层以上引线层130。第一基板110可以是玻璃等透明的绝缘基板，第一基板110也可以是聚酰亚胺(polyimide，PI)等材质的柔性透光绝缘基板。多个图案化电极120位于第一基板110上，并且设置在触摸感应区TS。两层以上引线层130设置在引线区LA，且叠设于第一基板110上。其中，每层引线层130包括多条电极引线131，多条电极引线131中的每个对应多个图案化电极120中的一个并电连接，相邻引线层130的多个电极引线131彼此绝缘。
本申请实施例的触摸感应装置100包括多条电极引线131，多条电极引线131在触摸感应装置100的厚度方向上呈两层以上布置，从而减小多条电极引线131在垂直于厚度方向的平面内所占据的面积，即减小引线区LA占据整个触摸感应装置100表面的面积。当触摸感应装置100应用于触控显示面板中时，引线区LA所占面积的减小使得触控显示面板能够实现 更窄边框的设计。
每层引线层130中的多条电极引线131彼此之间具有间隙133。其中，至少一层引线层130中的多条电极引线131在相邻层引线层130的投影覆盖相邻层引线层130的间隙133的至少部分。在一些实施例中，至少一层引线层130中的至少部分电极引线131的位置与相邻层引线层130的间隙133的位置对应。
每层引线层130中的多条电极引线131彼此之间具有间隙133，间隙133的至少部分被相邻层引线层130的多条电极引线131覆盖。具体地，间隙133被该多条电极引线131覆盖指间隙133被该多条电极引线131在该间隙133所在层引线层130的投影覆盖。一个间隙133的至少部分可以被单个电极引线131覆盖，也可以被两条或两条以上电极引线131覆盖。
如图2，在本实施例中，触摸感应装置100可以包括两层引线层130，即下层引线层130和上层引线层130，其中上层引线层130位于下层引线层130的上方。其中，上层引线层130的多条电极引线131均与下层引线层130的多条电极引线131错位设置，下层引线层130内的每个间隙133上方均对应设有一条上层引线层130的电极引线131。可选的，也可以是上层引线层130的电极引线131覆盖下层引线层130内的对应间隙133的一部分。
电极引线131可以是金属导电材料制成，其为不透光材料。当光线沿触摸感应装置100的厚度方向进行照射时，至少一层引线层130中的电极引线131能够对穿过相邻层引线层130内间隙133的光线进行至少部分遮挡。当触摸感应装置100应用于触控显示面板中时，在激光烧结等激光加工工艺中，两层以上引线层130的错位设置的多条电极引线131能够遮挡更多的激光，一定程度防止激光照射至引线层130下方引起的相应位置的损伤，从而提高触控显示面板的产品良率。
在一些实施例中，每层引线层130中的多条电极引线131等间距设置，多条电极引线131的线宽大于或等于间隙133的尺寸。如图2，例如在本实施例中，下层引线层130内的多条电极引线131等间距设置，使得下层引线层130内的每个间隙133的尺寸相同。下层引线层130内的每个间隙133 上方均对应设有一条上层引线层130的电极引线131，并且电极引线131的线宽大于间隙133的尺寸，使得上层引线层130的电极引线131能够将下层引线层130内的间隙133完整覆盖。
由于电极引线131的线宽大于或等于间隙133的尺寸，至少一层引线层130的多条电极引线131能够完整覆盖相邻层引线层130的间隙。当光线沿触摸感应装置100的厚度方向进行照射时，两层以上引线层130的多条电极引线131能够共同在光源方向的另一侧形成更加完整的光线遮挡区，从而在激光加工工艺中为设置在光线遮挡区内的其它部件形成保护，提高触摸感应装置100以及触控显示面板的产品良率。
每层引线层130还包括覆盖多条电极引线131的第一绝缘层132，以实现同层引线层130中相邻电极引线131之间的绝缘，以及实现相邻引线层130的电极引线131之间的绝缘。
每层引线层130的第一绝缘层132覆盖于触摸感应装置100的触摸感应区TS以及引线区LA。在一些实施例中，多个图案化电极120可以设置在两层以上引线层130中的顶层引线层130的第一绝缘层132上。
多个图案化电极120通过图案化导电材料制成，在一些实施例中例如是图案化的氧化铟锡(Indium tin oxide，ITO)，在其它一些实施例中，也可以是例如银纳米线(AgNW)的纳米金属线、石墨烯等透光率较高的材料制成。多个图案化电极120可以形成特定的图案阵列，以形成阵列排布的自电容或互电容，当手指或一些其它物体触摸到触摸感应装置时，触摸点附近的自电容或互电容的电容值发生改变。电极引线131能够将上述阵列排布的自电容或互电容与触摸控制电路连接，以实现自电容或互电容形成的阵列中各位置处的电容值的变化量，从而获知每个触摸点的坐标。
多个图案化电极120包括多个驱动电极以及多个感应电极，多条电极引线131包括多条驱动电极引线以及多条感应电极引线。多条驱动电极引线分别对应连接至多个驱动电极，多条感应电极引线分别对应连接至多个感应电极。其中，多条驱动电极引线在第一基板110上的投影与多条感应电极引线在第一基板110上的投影互不重叠，从而避免驱动电极引线与感应电极引线之间的干扰。
触摸感应装置100还包括第二绝缘层140，第二绝缘层140位于两层以上引线层130背离第一基板110的一侧。本实施例中，第二绝缘层140覆盖于触摸感应装置100的触摸感应区TS以及引线区LA，并且，第二绝缘层140覆盖多个图案化电极120。通过设置第二绝缘层140，避免触摸感应装置100的图案化电极120、电极引线131等导电结构裸露，提高触摸感应装置100的使用寿命和稳定性。
在一些实施例中，触摸感应装置100还包括屏蔽层150。屏蔽层150设置于引线区LA。在本实施例中，屏蔽层150位于两层以上引线层130上。具体地，两层以上引线层130上设置有第二绝缘层140，屏蔽层150设置在第二绝缘层140上。与现有的屏蔽层150与引线层130同层布置的触摸感应装置100相比，本申请实施例的触摸感应装置100的引线区LA占据整个触摸感应装置100表面的面积进一步减小，便于触控显示面板实现更窄边框的设计。同时，屏蔽层150单独占据一层，提高触摸感应装置100的抗干扰能力。
需要说明的是，屏蔽层150可以不限于是设置于两层以上引线层130上。屏蔽层150例如还可以设置在任意两层引线层130之间。
屏蔽层150可以位于两层以上引线层130背离第一基板的一侧，以避免或降低电极或电极引线受外围环境的电磁干扰。
可选的，屏蔽层150也可以位于两层或多层引线层130之间，多层引线层130之间可以只有一层屏蔽层150，也可以有多层屏蔽层150，多层屏蔽层150中的每一层可以分别位于每层引线层130之间，也可以位于部分引线层130之间；该设置方式既可以避免或降低电极或电极引线受外围环境的电磁干扰，同时也可以避免或降低相邻电极引线之间的电磁干扰。
屏蔽层150在第一基板110上的正投影与多条电极引线131在第一基板110上的正投影至少部分重叠。屏蔽层150与多条电极引线131能够共同形成叠层的遮光结构，当光线沿触摸感应装置100的厚度方向进行照射时，上述的遮光结构在光源方向的另一侧形成光线遮挡区。叠层的遮光结构能够在激光加工工艺中为设置在光线遮挡区内的其它部件形成更强的保护，进一步提高触摸感应装置100以及触控显示面板的产品良率。
其中，屏蔽层的材质可以是非透明的导电材料，例如是银(Ag)、钼(Mo)、铜(Cu)等金属材料，从而能够反射光线。
在上述实施例中，以触摸感应装置100包括两层引线层130为例进行了说明，在其它一些实施例中，引线层130的数量可以不限于是上述实施例中的示例。
图3是本申请另一实施例提供的触摸感应装置的截面示意图，该另一实施例的触摸感应装置的结构与前述实施例的触摸感应装置的结构具有类似的部分，以下将对两者的不同之处进行说明，相同之处不再详述。
在图3对应的实施例中，触摸感应装置100具有触摸感应区TS以及位于触摸感应区TS外周的引线区LA。触摸感应装置100包括第一基板110、多个图案化电极120以及两层以上引线层130，每层引线层130包括多条电极引线131以及覆盖多条电极引线131的第一绝缘层132。与前述实施例不同的是，本实施例的触摸感应装置100包括三层引线层130。
三层引线层130例如可以是自下而上叠层设置的下层引线层130、中层引线层130以及上层引线层130。在本实施例中，中层引线层130的多条电极引线131均与下层引线层130的多条电极引线131错位设置，下层引线层130内的每个间隙133上方均对应设有一条中层引线层130的电极引线131。上层引线层130的多条电极引线131均与中层引线层130的多条电极引线131错位设置，中层引线层130内的每个间隙133上方均对应设有一条上层引线层130的电极引线131。
当光线沿触摸感应装置100的厚度方向进行照射时，至少一层引线层130中的多条电极引线131能够对穿过相邻层引线层130内间隙133的光线进行至少部分遮挡。上层引线层130的多条电极引线131与下层引线层130的多条电极引线131位置对应，从而实现对光线进行遮挡的同时，使得错位设置的多层引线层130的排布更加合理，保证引线区LA占据整个触摸感应装置100表面的面积保持在较小的范围内。当触摸感应装置100应用于触控显示面板中时，引线区LA所占面积的减小使得触控显示面板能够实现更窄边框的设计。
每层引线层130中的多条电极引线131等间距设置，电极引线131的 线宽大于或等于间隙133的尺寸，使得至少一层引线层130的电极引线131能够完整覆盖相邻层引线层130的间隙。当光线沿触摸感应装置100的厚度方向进行照射时，多层引线层130的多条电极引线131能够共同在光源方向的另一侧形成更加完整的光线遮挡区，从而在激光加工工艺中为设置在光线遮挡区内的其它部件形成保护，提高触摸感应装置100以及触控显示面板的产品良率。
在上述实施例的触摸感应装置100中，触摸感应装置100包括三层引线层130。在其它一些实施例中，根据设计的需要，引线层130也可以调整为四层、五层等其它数量，相应地，与多个图案化电极120连接的多条电极引线131也配置为在触摸感应装置100厚度方向上设置的多层。通过将多条电极引线131多层设置，使得多条电极引线131在垂直于触摸感应装置100厚度方向的平面内所占据的面积进一步缩小，即减小引线区LA占据整个触摸感应装置100表面的面积，进一步方便包括该触摸感应装置100的触控显示面板实现更窄边框的设计。
本申请实施例还提供一种触控显示面板，图4、图5是本申请一种实施例提供的触控显示面板的俯视示意图、截面示意图，其中图4中BB线示出图5的截面示意图的截取位置。触控显示面板1000包括显示面板200以及触摸感应装置100，触摸感应装置100位于显示面板200上。在一些实施例中，触摸感应装置100可以是前述任一实施例的触摸感应装置100。

多个图案化电极120位于第一基板上，并且设置在触摸感应区TS。两层以上引线层130设置在引线区LA，且叠设于第一基板上，每层引线层130包括多条电极引线131，多条电极引线131中的每个对应多个图案化电极120中的一个并电连接，相邻引线层130的多条电极引线131彼此绝缘。
根据本申请实施例的触控显示面板1000，触摸感应装置100包括两层以上引线层130，每层引线层130包括多条电极引线131，使得触摸感应装置100的多条电极引线131在其厚度方向上呈两层以上布置，从而减小多 条电极引线131在垂直于厚度方向的平面内所占据的面积，即减小引线区LA占据整个触摸感应装置100表面的面积。进一步地，由于引线区LA所占面积的减小，使得触控显示面板1000能够实现更窄边框的设计。
每层引线层130还包括覆盖多条电极引线131的第一绝缘层132，以实现同层引线层130中相邻电极引线131之间的绝缘，以及实现相邻引线层130的电极引线131之间的绝缘。
每层引线层130的第一绝缘层132覆盖于触摸感应装置100的触摸感应区TS以及引线区LA。在一些实施例中，多个图案化电极120可以设置在两层以上引线层130中的顶层引线层130的第一绝缘层132上。

显示面板200具有显示区AA以及位于显示区AA外周的非显示区NA，触摸感应装置100的触摸感应区TS与显示面板200的显示区AA对应。封合胶230环绕设置于非显示区NA。
第二基板210例如是显示面板200的阵列基板，在一些实施例中，其包括位于显示区AA的像素电路以及发光元件等，发光元件例如可以是有机发光二极管(Organic Light-Emitting Diode，OLED)。在一些实施例中，第二基板210包括位于非显示区NA的布线结构211，该布线结构211例如是与OLED阴极电连接的布线结构。
两层以上引线层130的多条电极引线131在第二基板210上的正投影与布线结构211至少部分重叠，封合胶230位于布线结构211的外周侧。
触控显示面板1000在生产过程中，封合胶230可以通过激光烧结的方 式实现对第二基板210与封装基板220的粘合。其中，激光烧结宽度较大时，由于电极引线131在第二基板210上的正投影与布线结构211至少部分重叠，从而能够阻挡至少部分过宽激光照射在布线结构211上，减少对布线结构211的损伤，从而提高显示面板200及触控显示面板1000的使用寿命。
每层电引线层130中的多条电极引线131彼此之间具有间隙133。其中，至少一层引线层130中的多条电极引线131在相邻层引线层130的投影覆盖相邻层引线层130的间隙133的至少部分。在一些实施例中，至少一层引线层130中的至少部分电极引线131的位置与相邻层引线层130的间隙133的位置对应。
如图5，在本实施例中，触摸感应装置100可以包括两层引线层130，即下层引线层130和上层引线层130，其中上层引线层130位于下层引线层130的上方。其中，上层引线层130的多条电极引线131均与下层引线层130的多条电极引线131错位设置，下层引线层130内的每个间隙133上方均对应设有一条上层引线层130的电极引线131。可以理解的是，在其它一些实施例中，触摸感应装置100包括的引线层130的数量不限于是两层，还可以是三层、四层等其它数量。
电极引线131可以是金属导电材料制成，在一些实施例中其为不透光材料。当光线沿触控显示面板1000的厚度方向进行照射时，至少一层引线层130中的电极引线131能够对穿过相邻层引线层130内间隙133的光线进行至少部分遮挡。当触控显示面板1000处于激光烧结等激光加工工艺中时，两层以上引线层130的多条电极引线131的错位设置使得多条电极引线131在第二基板210上的正投影的集合能够与布线结构211更多地重叠，以能够遮挡更多的激光，一定程度防止激光照射至引线层130下方的布线结构211，减小对布线结构211的损伤，从而提高触控显示面板1000的产品良率。
在一些实施例中，每层引线层130中的多条电极引线131等间距设置，多条电极引线131的线宽大于或等于间隙133的尺寸。如图5，例如在本实施例中，下层引线层130内的多条电极引线131等间距设置，使得下层引 线层130内的每个间隙133的尺寸相同。下层引线层130内的每个间隙133上方均对应设有一条上层引线层130的电极引线131，并且电极引线131的线宽大于间隙133的尺寸，使得上层引线层130的电极引线131能够将下层引线层130内的间隙133完整覆盖。
由于电极引线131的线宽大于或等于间隙133的尺寸，至少一层引线层130的电极引线131能够完整覆盖相邻层引线层130的间隙。光线沿触摸感应装置100的厚度方向进行照射时，两层以上引线层130的多条电极引线131共同在光源方向的另一侧形成更加完整的光线遮挡区，在一些实施例中，该更加完整的光线遮挡区能够覆盖布线结构211，从而在激光加工工艺中为布线结构211形成保护，提高触控显示面板1000的产品良率。
多个图案化电极120包括多个驱动电极以及多个感应电极，多条电极引线131包括多条驱动电极引线以及多条感应电极引线。多条驱动电极引线分别对应连接至多个驱动电极，多条感应电极引线分别对应连接至多个感应电极。其中，多条驱动电极引线在第一基板110上的投影与多条感应电极引线在第一基板110上的投影互不重叠，从而避免驱动电极引线与感应电极引线之间的干扰。
触摸感应装置100还包括第二绝缘层140，第二绝缘层140位于两层以上引线层130背离第一基板110的一侧。本实施例中，覆盖于触摸感应装置100的触摸感应区TS以及引线区LA，并且，第二绝缘层140覆盖多个图案化电极120。通过设置第二绝缘层140，避免触摸感应装置100的图案化电极120、电极引线131等导电结构裸露，提高触摸感应装置100的使用寿命和稳定性。
触摸感应装置100还包括屏蔽层150，屏蔽层150设置于引线区LA。
屏蔽层150位于两层以上引线层130上。在本实施例中，两层以上引线层130上设置有第二绝缘层140，屏蔽层150设置在第二绝缘层140上。与现有的屏蔽层150与引线层130同层布置的触摸感应装置100相比，本申请实施例的触摸感应装置100的引线区LA占据整个触摸感应装置100表面的面积进一步减小，便于触控显示面板实现更窄边框的设计。同时，屏蔽层150单独占据一层，提高触摸感应装置100的抗干扰能力。
需要说明的是，屏蔽层150可以不限于是设置于两层以上引线层130上。在其它一些实施例中，屏蔽层150例如还可以设置在任意两层引线层130之间。
屏蔽层150可以位于两层以上引线层130背离第一基板的一侧，以避免或降低电极或电极引线受外围环境的电磁干扰。
屏蔽层150也可以位于两层或多层引线层130之间，多层引线层130之间可以只有一层屏蔽层150，也可以有多层屏蔽层150，多层屏蔽层150中的每一层可以分别位于每层引线层130之间，也可以位于部分引线层130之间；该设置方式既可以避免或降低电极或电极引线受外围环境的电磁干扰，同时也可以避免或降低相邻电极引线之间的电磁干扰。
屏蔽层150在第二基板210上的正投影与布线结构211至少部分重叠，使得触控显示面板1000在激光烧结工艺中，屏蔽层150能够阻挡至少部分过宽激光照射在布线结构211上，进一步减少对布线结构211的损伤，提高触控显示面板1000的使用寿命。
其中，屏蔽层的材质可以是非透明的导电材料，例如是银(Ag)、钼(Mo)、铜(Cu)等金属材料，从而能够反射光线。
本申请实施例还提供一种触控显示面板母板，图6是本申请一种实施例提供的触控显示面板母板的俯视示意图。触控显示面板母板可以包括多个触控显示面板1000，其中触控显示面板1000可以为上述任一实施例的触控显示面板1000。多个触控显示面板1000排列为多行，每行中的相邻触控显示面板1000之间距离为零，即每行中的相邻触控显示面板1000之间零间距设置。
根据本申请实施例的触控显示面板母板，多个触控显示面板1000排列为多行，每行中的相邻触控显示面板1000之间零间距设置，从而提高触控显示面板母板的利用率，降低生产成本。
可选的，每个触控显示面板1000包括显示面板200以及触摸感应装置100，触摸感应装置100位于显示面板200上。
触摸感应装置100具有触摸感应区TS以及位于触摸感应区TS外周的引线区LA。触摸感应装置100包括第一基板、多个图案化电极120以及两 层以上引线层130。多个图案化电极120位于第一基板上，并且设置在触摸感应区TS。两层以上引线层130设置在引线区LA，且叠设于第一基板上，每层引线层130包括多条电极引线131，每条电极引线131对应一个图案化电极120并与图案化电极120电连接，相邻引线层130的电极引线131彼此绝缘。
显示面板200包括第二基板210以及封装基板220。封装基板220位于第二基板210上，其中封装基板220与第二基板210通过封合胶230粘合。
两层以上引线层130的多条电极引线131在第二基板210上的正投影的集合与布线结构211至少部分重叠，封合胶230位于布线结构211的外周侧。
触摸感应装置100包括屏蔽层150，屏蔽层150设置于引线区LA。其中，屏蔽层的材质可以是非透明的导电材料，例如是银(Ag)、钼(Mo)、铜(Cu)等金属材料，从而能够反射光线。
