为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动
前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
图1为现有技术提供的一种显示面板的剖面图，如图1所示，该显示面板包括阵列基板110、盖板120和触控驱动板130。其中，阵列基板110是一种集成有显示模组的基板，盖板120是一种集成有触控模组的透明基板，触控驱动板130是一种驱动显示触控模组检测触控信号的电路板。
具体地，盖板120设置于阵列基板110上，触控驱动板130设置于盖板120远离阵列基板110的一面上。为了触控驱动板130可以完全绑定于盖板120的绑定区，一般沿水平方向设置触控驱动板130的漏铜区的长度大于绑定区，因此在触控驱动板130绑定于盖板120的绑定区后，会存在部分漏铜区没有与绑定区绑定在一起。另外，阵列基板110的长度大于盖板120的长度，从而使没有与绑定区绑定在一起的部分漏铜区因阵列基板110的遮挡，无法使用常规背侧涂胶工艺进行涂胶，从而导致触控驱动板130没有与绑定区绑定在一起的部分漏铜区无法阻止水汽盐雾的腐蚀，进而使显示面板的防水防盐雾性能差。
针对上述指出的显示面板的防水防盐雾性能差的问题，本申请实施例提供了一种显示面板，可以阻止水汽盐雾等侵入显示面板，以提高显示面板防水防盐雾的能力。
图2为本申请实施例提供的一种显示面板的剖面图，参考图2，该显示面板包括：阵列基板110、盖板120和触控驱动板130；盖板120设置于阵列基板110上，盖板120远离阵列基板110的一面包括触控驱动板绑定区A，触控驱动板绑定区A包括第一绑定区A1和第二绑定区A2，第

其中，触控驱动板绑定区A为盖板120与触控驱动板130进行绑定的区域。触控驱动板130包括的第一导电部为触控驱动板130被暴露出来的导电层，触控驱动板130包括的第二导电部为触控驱动板130未被暴露出来的导电层。由此，沿垂直于盖板120方向，触控驱动板130包括第二导电部区域的厚度大于触控驱动板130包括第二导电部区域的厚度。触控驱动板绑定区A包括的第一绑定区A1和第二绑定区A2呈阶梯排布，也就是第二绑定区A2远离阵列基板110的面到阵列基板110的距离小于第一绑定区A1远离阵列基板110的面到阵列基板110的距离，由此第二绑定区A2可以容纳下触控驱动板130包括的第二导电部区域。具体地，触控驱动板绑定区A包括的第一绑定区A1可以实现盖板120与第一导电部实现电连接，触控驱动板绑定区A包括的第二绑定区A2可以容纳第一导电部未与盖板120电连接的部分和第二导电部，由此可以使第一导电部未与盖板120电连接的部分被第二绑定区A2遮挡，以改善第一导电部未与盖板120电连接的部分直接暴露于空气中无法阻止水汽盐雾的腐蚀的问题，进而提高显示面板防水防盐雾的能力。
综上，本申请实施例提供的显示面板，盖板120设置于阵列基板110上，盖板120远离阵列基板110的一面包括触控驱动板绑定区A，触控驱动板绑定区A包括第一绑定区A1和第二绑定区A2，第一绑定区A1和第二绑定区A2呈阶梯排布，也就是第二绑定区A2远离阵列基板110的面到阵列基板110的距离小于第一绑定区A1远离阵列基板110的面到阵列基板110的距离。触控驱动板130包括第一导电部和第二导电部，第一导电部暴露，第二导电部非暴露，由此沿垂直于盖板120方向，触控驱动板130包括第二导电部区域的厚度大于触控驱动板130包括第二导电部区域的厚度。另外，第一导电部设置于第一绑定区A1和部分第二绑定区A2，第二导电部设置于第二绑定区A2，即第一绑定区A1可以实现盖板120与第一导电部实现电连接，第二绑定区A2可以容纳第一导电部未与盖板
120电连接的部分和第二导电部，由此可以使第一导电部未与盖板120电连接的部分被第二绑定区A2遮挡，以改善第一导电部未与盖板120电连接的部分直接暴露于空气中无法阻止水汽盐雾的腐蚀的问题，进而提高显示面板防水防盐雾的能力。
在上述实施例的基础上，图3为本申请实施例提供的一种触控驱动板的剖视图，参考图2-图3，触控驱动板130包括依次层叠设置的第一绝缘层131、导电层132以及第二绝缘层133；第二绝缘层133覆盖部分导电层132；第一导电部1321包括未被第二绝缘层133覆盖的导电层132，第二导电部1322包括被第二绝缘层133覆盖的导电层132；沿第一绑定区A1指向第二绑定区A2的方向，第一导电部1321的长度大于第一绑定区A1的长度。
其中，第一绝缘层131和第二绝缘层133可以具有保护导电层132不受机械损伤、化学腐蚀、不接触水蒸汽受潮以及防止接触导体触电等作用，可增强触控驱动板130强度和延长触控驱动板130的使用寿命。导电层132可以实现触控驱动板130与盖板120之间的电信号传输。
具体地，触控驱动板130通过第一导电部与盖板120电连接，为了保证触控驱动板130的第一导电部与盖板120的第一绑定区A1电连接的稳定性，即触控驱动板130的第一导电部与盖板120的第一绑定区A1绑定的稳定性，一般沿第一绑定区A1指向第二绑定区A2的方向设置触控驱动板130的第一导电部的长度大于第一绑定区A1的长度，因此在第一导电部1321绑定于第一绑定区A1后，会存在部分第一导电部1321没有与第一绑定区A1绑定在一起，需要将剩余的第一导电部1321容纳于第二绑定区A2，使第一导电部未与盖板120电连接的部分被第二绑定区A2遮挡，以改善第一导电部未与盖板120电连接的部分直接暴露于空气中无法阻止水汽盐雾的腐蚀的问题，进而提高显示面板防水防盐雾的能力。
在上述实施例的基础上，可选的，继续参考图2-图3，沿垂直于盖板120方向，第一绑定区A1和第二绑定区A2之间的阶梯深度大于或等于第二绝缘层133的厚度。
具体地，由于第二绑定区A2可以容纳第一导电部未与盖板120电连接的部分和第二导电部，并且与第一绑定区A1等长的第一导电部设置于
第一绑定区A1，由此第一导电部与第一绑定区A1接触的面齐平。然而，第二导电部和第一导电部均为触控驱动板130的导电层132，二者的区别为是否在朝向阵列基板110的一面设置有第二绝缘层133，为了保证触控驱动板130远离盖板120的一面保持齐平，沿垂直于盖板120方向，第一绑定区A1和第二绑定区A2之间的阶梯深度需要设置为大于或等于第二绝缘层133的厚度。由此，第二绑定区A2可以容纳第二导电部，并且可以使触控驱动板130远离盖板120的一面保持齐平。
在上述实施例的基础上，图4为本申请实施例提供的另一种显示面板的剖面图显示面板，参考图3和图4，显示面板还包括第一导电胶层140，第一导电胶层140覆盖第一绑定区A1和第二绑定区A2；第一绑定区A1设置有第一绑定引脚121，第一绑定引脚121通过第一导电胶层140和第一导电部电连接；沿垂直于盖板120的方向，第一绑定区A1覆盖的第一导电胶层140的厚度与第一绑定区A1和第二绑定区A2之间的阶梯深度的和等于第二绝缘层133的厚度与第二绑定区A2覆盖的第一导电胶层140的厚度的和。
其中，第一导电胶层140是一种固化或干燥后具有一定导电性的胶粘剂。它可以将盖板120和触控驱动板130连接在一起，使盖板120和触控驱动板130间形成导电通路。第一绑定引脚121是从盖板120内部的设置的触控模组引出地与触控驱动板130电连接的引脚。
具体地，第一导电胶层140覆盖第一绑定区A1和第二绑定区A2，且第一绑定区A1设置有第一绑定引脚121，即第一导电胶层140覆盖第一绑定引脚121和第二绑定区A2。由此，第一绑定引脚121可以通过第一导电胶层140和第一导电部电连接；第一导电胶层140还可以充分填充于第一绑定区A1和第一导电部之间的缝隙、第二绑定区A2和第一导电部之间的缝隙以及第二绑定区A2和第二绝缘层133之间的缝隙，使盖板120和触控驱动板130很好地粘连在一起；第一导电胶层140还可以使所有的第一导电部与第一绑定引脚121电连接，进一步扩大了第一导电部与第一绑定引脚121之间的导电面积。
另外，沿垂直于盖板120的方向，第一绑定区A1覆盖的第一导电胶层140的厚度与第一绑定区A1和第二绑定区A2之间的阶梯深度的和等
于第二绝缘层133的厚度与第二绑定区A2覆盖的第一导电胶层140的厚度的和，可以使触控驱动板130远离盖板120的一面与水平面保持齐平。
在上述实施例的基础上，可选地，图5为本申请实施例提供的另一种显示面板的剖面图，如图5所示，显示面板还包括显示驱动板150；阵列基板110设置盖板120的面包括显示驱动板绑定区B，显示驱动板150设置于显示驱动板绑定区B；盖板120的触控驱动板绑定区A与阵列基板110的显示驱动板绑定区B同侧。
其中，显示驱动板150是一种驱动显示模组产生发光的电路板。显示驱动板150设置于显示驱动板绑定区B，使显示驱动板150与阵列基板110电连接，以驱动阵列基板110显示画面。另外，盖板120的触控驱动板绑定区A可以设置在与阵列基板110的显示驱动板绑定区B同侧，即使显示驱动板150与触控驱动板130同侧，由此可以减小显示面板的设计体积。
在上述实施例的基础上，可选地，图6为本申请实施例提供的一种显示面板的俯视图，如图6所示，显示面板垂直于盖板120的方向，触控驱动板130的垂直投影与显示驱动板150的垂直投影不重合。
具体地，垂直于盖板120的方向，设置触控驱动板130的垂直投影与显示驱动板150的垂直投影不重合，可以避免触控驱动板130和显示驱动板150破损发生电连接。另外，设置触控驱动板130的垂直投影与显示驱动板150的垂直投影不重合相比于设置触控驱动板130的垂直投影与显示驱动板150的垂直投影重合，说明触控驱动板130和显示驱动板150的设置位置相对分散，更加有利于触控驱动板130和显示驱动板150的散热，以提高有利于触控驱动板130和显示驱动板150的使用寿命。
在上述实施例的基础上，可选地，图7为本申请实施例提供的另一种显示面板的剖面图，如图7所示，显示面板还包括第二导电胶层160；显示驱动板150绑定区设置有第二绑定引脚151；第二导电胶层160覆盖显示驱动板绑定区B，第二绑定引脚通过第二导电胶层160与显示驱动板150电连接。
具体地，第二导电胶层160是一种固化或干燥后具有一定导电性的胶粘剂。它可以将阵列基板110和显示驱动板150连接在一起，使阵列基板
110和显示驱动板150间形成导电通路。第二绑定引脚是从阵列基板110内部的设置的显示模组引出的与显示驱动板150电连接的引脚。
具体地，第二导电胶层160覆盖显示驱动板绑定区B，且显示驱动板绑定区B设置有第二绑定引脚121，即第二导电胶层160覆盖第二绑定引脚121。由此，第二导电胶层160不仅实现了第二绑定引脚和显示驱动板150之间的电连接，而且还实现了将显示驱动板150绑定于显示驱动板绑定区B。
可选地，显示驱动板包括柔性电路板。
具体地，柔性电路板(Flexible Printed Circuit，FPC)是以聚酰亚胺或聚酯薄膜为基材制成的一种具有高度可靠性，绝佳的可挠性印刷电路板。具有配线密度高、重量轻、厚度薄、弯折性好等特点。由此，使用柔性电路板制作的显示驱动板具有配线密度高、重量轻、厚度薄、弯折性好等特点。
可选地，触控驱动板包括转接柔性排线。
具体地，在目前的显示模组行业中，用于模组点亮的转接柔性排线(transition flexible printed circuit，tfpc)，可以起到连接测试主板、治具与显示模组的作用，其功能是实现电信号传输，具有配线密度高、重量轻、厚度薄、弯折性好等特点。因此，使用转接柔性排线制作触控驱动板可以很好地传输触控信号，并且具有配线密度高、重量轻、厚度薄、弯折性好等特点。
在上述实施例的基础上，可选地，图8为本申请实施例提供的一种显示装置的结构示意图，如图8所示，该显示装置200包括本申请任意实施例提出的显示面板100，因此具备本申请任意实施例提供的显示面板100的有益效果，此处不再赘述。
