本公开涉及显示技术领域，尤其涉及一种显示面板及显示装置和触控信号的处理方法。
背景技术
相关技术中，手机、平板电脑等电子设备大部分使用具有触控功能的显示面板，将触控传感器与显示面板的像素单元相集成，以降低显示面板的厚度，通常称作touch in cell或in cell显示面板。
然而这种显示面板的集成度较高，导致触控传感器与其他结构之间的距离过近，显示面板使用过程中会产生变化的电流信号，而触控传感器采集触控信号的同时，也可能采集到这些信号，而这些信号可能对触控信号的结果精度造成一定影响。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开提供了一种显示面板。
在一个具体实施方式中，显示面板包括衬底基板，显示面板上包括多个像素单元，衬底基板上还设有触控传感器，其中，衬底基板及多个像素单元的具体结构可以一定程度上参考相关技术，此处不做进一步限定和描述。
如图1所示，在一个具体实施方式中，触控传感器110包括多个接收电极(Rx)111和多个发射电极(Tx)112，接收电极和发射电极统称为子触控电极。
该具体实施方式中，多个接收电极111横向设置，多个发射电极112纵向设置，且每一行内的接收电极111之间电连接，并与一根数据线电连接，每一列内的发射电极112之间电连接，并与一根数据线电连接。多个接收电极111和多个发射电极112之间则是绝缘设置。
显然，在其他一些具体实施方式中，触控传感器110的结构还可以相应的作出调整，此处不作限定。
图2是本公开实施例提供的显示面板的又一结构示意图。
如图2所示，显示面板还包括信号噪声传感器120，该信号噪声传感器120主要用于检测显示面板扫描过程中产生的信号噪声。
信号噪声传感器120所检测到的信号噪声和传递至触控传感器110处的 信号噪声是基本相同的，这样，可以认为信号噪声传感器120所检测到的信号噪声也就是对触控传感器110的检测结果造成影响的信号噪声，因此，根据信号噪声传感器120的检测结果对触控传感器110的检测结果进行降噪处理，有助于提高触控信号的信噪比，从而提高触控信号的质量。
这样，本公开实施例中，通过信号噪声传感器120采集显示面板扫描过程中产生的信号噪声，以便根据检测结果对采集到的触控信号进行降噪处理，有助于相对准确地确定信号噪声，从而有针对性地进行降噪处理，有助于提高触控信号的精度。
可选地，在一个具体实施方式中，信号噪声传感器120包括多个检测电极121，多个检测电极121之中的全部或部分电连接。
例如，可以将多个检测电极121划分为几个区域，每一个区域内的检测电极121之间电连接，以有针对性地采集相对应的区域内的信号噪声，有利于提高对于信号噪声的采集精度。其中，所述每一个区域的覆盖面积小于所述多个检测电极的覆盖面积。
在另一个可选的具体实施方式中，各检测电极121之间均电连接，这样，各检测电极121可以通过同一连接线输出采集到的信号噪声，也可以通过多根相并联的连接线输出采集到的信号噪声，有利于提高信号噪声输出的稳定性。
这些检测电极121的分布区域与触控传感器110的分布区域是相同的，以提高对于可能影响触控传感器110的信号噪声的检测结果，各检测电极121之间电连接，这样，相当于提高了信号噪声传感器120的检测范围，有利于提高对于信号噪声的检测精度。
可选地，在一个具体实施方式中，该显示面板还包括虚设电极130(dummy pattern)，虚设电极130与多个检测电极121同层同材料设置，各虚设电极130之间电绝缘，虚设电极130与多个检测电极121之间电绝缘。
本实施例中，虚设电极130的具体结构和作用均可参考相关技术，此处不再赘述，与相关技术的主要区别在于，本实施例中将部分或全部制作虚设电极130过程中形成的图形作为信号噪声传感器120的电极。
如图2所示，可以理解为，在制作虚设电极130过程中所形成的图形中， 不与其他结构电连接的部分，仍作为虚设电极130使用，其功能可参考相关技术，而与其他结构电连接且通过数据线输出信号的部分，作为信号噪声传感器120的检测电极121使用。
也就是说，虚设电极130与检测电极121同层同材料设置，这样，可以通过一次构图工艺完成虚设电极130和多个检测电极121的制作，只需要改变曝光过程中所使用的掩膜版(mask)的形状即可，这样，相对于相关技术，本实施例的技术方案并不会显著增加成本，即可完成对于信号噪声传感器120的制作。
进一步的，各检测电极121之间通过桥接线122电连接，桥接线122与检测电极121同层同材料设置。
在一个具体实施方式中，单独制作连接各检测电极121的桥接线122；在另一个具体实施方式中，则是桥接线122与检测电极121同层同材料设置。
在一个具体实施方式中，桥接线122的延伸方向与接收电极111和发射电极112之间的排布方向交叉。
图3是本公开实施例提供的显示面板的局部放大示意图，如图3所示，当检测电极121嵌入接收电极111中时，检测电极121与接收电极111之间存在第一间隔200，用于使检测电极121与接收电极111之间绝缘，桥接线122与接收电极111之间第二间隔210，用于使桥接线122与接收电极111之间电绝缘。第一间隔200与第二间隔210可以相同，也可以不同。图3的局部放大示意图与图4的位置关系示意图对应。
图4是本公开实施例提供的检测电极和子触控电极的一位置关系示意图；如图4所示，多个检测电极与多个子触控电极同层设置，且多个检测电极与多个子触控电极之间电绝缘。检测电极121的外轮廓位于接收电极111的外轮廓之内，且与接收电极111之间具有一定间隔。接收电极111通过桥电极150电连接。桥电极150位于薄膜封层(TFE)和缓冲层(buffer)形成的膜层160之上，第一绝缘层180用于使接收电极111和发射电极112之间绝缘，且用于使发射电极112与桥电极150之间绝缘。
需要说明的是，发射电极112也可通过桥电极150连接，二者择一通过桥电极连接。另外，桥电极可位于接收电极111或发射电极112之上，也可 位于接收电极111或发射电极112之下。
图5是本公开实施例提供的检测电极和子触控电极的又一位置关系示意图。如图5所示，多个检测电极与多个子触控电极不同层设置，且多个检测电极与多个子触控电极之间电绝缘。检测电极121位于接收电极111之上，且检测电极121与接收电极111之间具有第二绝缘层190。接收电极111通过桥电极150连接。桥电极150位于薄膜封层(TFE)和缓冲层(buffer)形成的膜层160之上，第一绝缘层180用于使接收电极111和发射电极112之间绝缘，且用于使发射电极112与桥电极150之间绝缘。
图6是本公开实施例提供的检测电极和子触控电极的又一位置关系示意图。如图6所示，多个检测电极与多个子触控电极不同层设置，且多个检测电极与多个子触控电极之间电绝缘。检测电极121与桥电极150同层。接收电极111通过桥电极150连接。桥电极150与检测电极121位于薄膜封层(TFE)和缓冲层(buffer)形成的膜层160之上，第一绝缘层180用于使接收电极111和发射电极112之间绝缘，且用于使发射电极112与桥电极150之间绝缘。
多个检测电极121之中的全部或部分电连接，并连接至连接线，所检测到的信号噪声通过相应的连接线传输。
在一个具体实施方式中，本公开的显示面板还包括：噪声检测信号线170，一端与所述多个检测电极121电连接，另一端接入触控控制芯片140。
可以理解为，在一次曝光、显影等操作过程中(或称一次mask工艺)，即可完成对于虚设电极130、检测电极121和桥接线122的制作，这样，只需要调整掩膜版的形状，制作过程中，其他工序和步骤均可参考相关技术，这样，在相对于相关技术显示面板不显著增加成本的情况下，即可制作出来包括上述检测电极121和桥接线122的显示面板。
触控传感器110包括多个接收电极111和多个发射电极112，检测电极121对应相应的接收电极111或发射电极112设置，以更加准确的检测相应的接收电极111和发射电极112处可能接收到的信号噪声，有利于提高对于信号噪声的检测精度。
这样，本发明实施例中，通过设置信号噪声传感器，以通过该信号噪声传感器采集显示面板扫描过程中产生的信号噪声，以便根据检测结果对采集 到的触控信号进行降噪处理，有助于相对准确地确定信号噪声，从而有针对性地进行降噪处理，有助于提高触控信号的精度。
本公开实施例提供了一种显示装置，包括以上任一种显示面板。
由于本实施例的技术方案包括上述实施例的全部技术方案，因此至少能实现上述全部技术效果，此处不再赘述。
可选地，如图10所示，还包括触控控制芯片140，触控传感器和信号噪声传感器120均与触控控制芯片140电连接，触控控制芯片140用于根据信号噪声传感器120检测到的扫描过程中产生的信号噪声对触控传感器的检测结果进行降噪处理。
该触控控制芯片140可参考相关技术中的触控控制芯片140，与相关技术的主要区别在于，本实施例中的触控控制芯片140还与信号噪声传感器120相连，以获取信号噪声传感器120检测到的信号噪声，这样，在信号处理过程中，只需要对其信号处理算法进行调整，不需要增加其他硬件成本，即可完成对于触控传感器的检测结果的降噪处理。
本公开还提供了一种显示面板的制作方法。
如图7所示，该显示面板的制作方法包括以下步骤：
步骤701：提供一衬底基板；
步骤702：在所述衬底基板上制作信号噪声传感器，所述信号噪声传感器用于检测所述显示面板扫描过程中产生的信号噪声；
步骤703：在所述信号噪声传感器的同层制作触控传感器，或在所述信号噪声传感器远离所述衬底基板的一侧制作触控传感器。
本实施例的技术方案中，衬底基板以及触控传感器的制作过程均可参考相关技术，此处不再赘述。
本实施例中，在制作触控传感器之前还包括制作信号噪声传感器的步骤。
制作过程中，可选地，所述显示面板包括虚设电极，所述信号噪声传感器包括多个检测电极，所述在所述衬底基板上制作信号噪声传感器，包括：
通过一次构图工艺制作所述虚设电极和所述多个检测电极，如果需要的话，还可以通过一次构图工艺制作连接各检测电极的桥接线。
可以理解为本实施例的技术方案中，通过一次mask工艺即可完成对于虚 设电极、检测电极和桥接线的制作，这样，只需要调整掩膜版的形状，制作过程中，其他工序和步骤均可参考相关技术，这样，在相对于相关技术显示面板不显著增加成本的情况下，即可制作出来包括上述检测电极和桥接线的显示面板。
本公开还提供了另一种显示面板的制作方法。
如图8所示，该显示面板的制作方法包括以下步骤：
步骤801：提供一衬底基板；
步骤802：在所述衬底基板上制作触控传感器；
步骤803：在所述触控传感器远离所述衬底基板的一侧制作信号噪声传感器，所述信号噪声传感器用于检测所述显示面板的信号噪声。
本实施例的技术方案中，衬底基板以及触控传感器的制作过程均可参考相关技术，此处不再赘述。
可选地，所述显示面板包括虚设电极，所述信号噪声传感器包括多个检测电极，所述在所述触控传感器远离所述衬底基板的一侧制作信号噪声传感器，包括：
通过一次构图工艺制作所述虚设电极和所述多个检测电极。
本公开还提供了一种触控信号的处理方法，应用于以上任一项所述的显示装置。
如图9所示，在一个实施例中，该触控信号的处理方法包括以下步骤：
步骤901：获取触控传感器采集的触控信号和信号噪声传感器采集的信号噪声；
步骤902：根据信号噪声对所述触控信号进行降噪处理。
如图10所示，使用过程中，通过触控传感器110采集的触控信号，通过信号噪声传感器120采集的信号噪声，然后将采集到的触控信号和信号噪声输入触控控制芯片140进行降噪处理，获得降噪后的触控信号。
信号噪声传感器120所检测到的信号噪声和传递至触控传感器110处的信号噪声是基本相同的，这样，可以认为信号噪声传感器120所检测到的信号噪声也就是对触控传感器110的检测结果造成影响的信号噪声。因此，根据信号噪声传感器120的检测结果对触控传感器110的检测结果进行降噪处 理，有助于提高触控信号的信噪比，从而提高触控信号的质量。
如图11所示，在一个具体实施方式中，直接对触控信号和信号噪声做差处理，即利用触控信号减去信号噪声，由于触控信号和信号噪声的时序是相同的，所以，触控信号减去信号噪声获得的结果，相当于去除了检测到的信号噪声，而保留了有用的触控信号，能够显著提高触控信号的信噪比，提高触控信号的质量。
图11中，左侧为触控传感器直接采集到的信号，右图为经过降噪处理的信号，其中，波浪状信号代表信号噪声，水平波形的信号代表触控信号，其中，低电平为未触控状态，高电平代表触控状态。可见，左图中触控传感器直接采集到的信号包括较大的信号噪声，根据所采集到的信号噪声对触控传感器采集到的信号进行降噪处理后，得到右图中所示信号，其中，信号噪声显著降低，信号的信噪比显著提高，也就是说，最终获得的触控信号的质量显著提高。
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，可轻易想到变化或替换，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权利要求的保护范围为准。
