Description

触控显示面板及触控显示装置
本申请要求于2020年8月11日递交的中国专利申请第202010801070.2号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
技术领域
本申请涉及触控显示技术领域，具体涉及一种触控显示面板及触控显示装置。
背景技术
随着显示面板技术的不断发展，人们对于大屏显示的需求也越来越高，而大屏的显示面板，例如全面屏手机等，都面临着一些设计以及制造工艺上的难点，比如，在听筒、前置摄像头的位置处，触控及显示需要做开槽避让，这样会导致听筒、前置摄像头的位置处的触控单元格部分会被切断开，被切断后剩余的触控单元格很小，很难保证开槽边缘的触控性能。因此，亟需一种能够保证开槽边缘的触控性能的显示面板结构。
发明内容
有鉴于此，本申请提供一种触控显示面板及触控显示装置，可以解决上述开槽以及边缘区的触控性能较差的问题。
本申请第一方面提供一种触控显示面板，该触控显示面板设有显示区且包括位于显示区的一触控电极组，所述触控电极组包括：多个第一触控单元，包括沿一第一方向设置的多个第一触控电极块以及沿与所述第一方向交叉的第二方向设置的多个第二触控电极块，所述多个第一触控电极块沿所述第一方向连接以形成多条第一触控电极，所述第二触控电极块沿所述第二方向连接以形成多条第二触控电极，所述第一触控电极与所述第二触控电极相互绝缘且交叉设置；至少一个异形触控单元，与所述第一触控单元相邻且包括沿所述第一方向设置的第一异形触控电极块和沿所述第二方向设置的第二异形触控电极块至少其中之一；以及异形触控补偿电容，包括连接所述第一异形触控电极块或所述第一触控电极块的第一异形触控引线以及连接所述第二异形触控电极块或所述第二触控电极块的第二异形触控引线，所述第一异形触控引线与所述第二异形触控引线相互绝缘且交叉设置。
根据本申请的另一方面，本申请一实施例提供的一种触控显示装置，包括触控显示面板。
本申请实施例提供的一种触控显示面板及触控显示装置，通过在显示区内的异形触 控单元内设置连接第一异形触控电极块或第一触控电极块的第一异形触控引线、连接第二异形触控电极块或第二触控电极块的第二异形触控引线，并且第一异形触控引线与第二异形触控引线绝缘交叉形成异形触控补偿电容，从而避免异形触控单元因开槽或边缘区切断而导致第一触控电极或第二触控电极被切断，即避免异形触控单元触控性能较差的情况，从而保证了异形触控单元的触控性能。
附图说明
图1所示为本申请一实施例提供的一种触控显示面板的结构示意图。
图2所示为本申请另一实施例提供的一种触控显示面板的结构示意图。
图3所示为本申请另一实施例提供的一种触控显示面板的结构示意图。
具体实施方式
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。
如图1所示，触控显示面板、设有显示区1，且包括位于显示区1的触控电极组。触控电极组包括多个第一触控单元30，所述第一触控单元30包括沿一第一方向设置的多个第一触控电极块11以及沿与所述第一方向交叉的第二方向设置的多个第二触控电极块21。所述多个第一触控电极块11沿所述第一方向连接以形成多条第一触控电极10，所述第二触控电极块21沿所述第二方向连接以形成多条第二触控电极20，所述第一触控电极10与所述第二触控电极20相互绝缘且交叉设置并在相交处形成若干第一桥点31。
触控电极组还包括与第一触控单元30相邻的至少一个异形触控单元40，异形触控单元40包括沿第一方向设置的第一异形触控电极块41和沿第二方向设置的第二异形触控电极块42中至少一个。触控电极组还包括异形触控补偿电容，该异形触控补偿电容包括第一异形触控引线43以及与第一异形触控引线43相互绝缘且交叉设置的第二异形触控引线44。第一异形触控引线43用于连接至第一异形触控电极块41或第一触控电极块11，第二异形触控引线44用于连接至第二异形触控电极块42或第二触控电极块21。
例如，在本申请实施例中，异形触控单元40的面积小于第一触控单元30的面积。具体的，第一异形触控电极块41的面积小于两个第一触控电极块11的面积，第二异形触控电极块42的面积小于两个第二触控电极块21的面积。即，第一异形触控电极块可以为一个，也可以为两个，不管第一异形触控电极块是一个还是两个，第一异形触控电极块的总的面积小于第一触控电极块即可。第二异形触控电极块可以为一个，也可以为两个，只需要第二异形 触控电极块的总的第二异形触控电极块的面积小于第二触控电极块即可。本申请实施例中可以通过减小第一异形触控电极块的面积，可以减小第二异形触控电极块的面积，也可以同时减小第一异形触控电极块的面积和第二异形触控电极块的面积来实现。
另外，异形触控单元40的第一异形触控电极块41和第二异形触控电极块42不重叠，即第一异形触控电极块41和第二异形触控电极块42不形成桥点，此时，第一异形触控电极块设有第一异形触控电极线且第二异形触控电极块设有第二异形触控电极线。
第一触控单元30是指完整的一个触控单元，例如显示区1内非边界位置的触控单元。完整的多个触控单元构成完整的第一触控电极10和第二触控电极20。每一第一触控电极10呈条状结构，每一第二触控电极呈条状结构。
在一个实施方式中，每一第一触控单元30中的第一触控电极块和第二触控电极块的数目均为两个，该两个第一触控电极块与该两个第二触控电极块相互绝缘且交叉设置。
由于很多的显示面板(例如手机等的显示面板)都有通话和拍照的功能，而实现通话功能通常需要设置听筒，实现拍照功能也需要设置摄像头，特别是前置摄像头，而设置听筒和前置摄像头都需要在显示面板的显示一侧的触控膜层和显示膜层上开槽，从而形成异形触控单元。随着人们对大屏显示的不断追求，窄边框和全面屏已经越来越多了，而要实现窄边框和全面屏，就需要在显示面板的边缘处也实现显示和触控功能，也就是说，在显示面板的边缘处也需要设置触控单元。然而在靠近显示面板边缘(特别是异形边缘，例如弧形边缘等)或者是靠近开槽位置处的触控单元格很可能不是正常的触控单元，即该处的触控单元为异形触控单元。针对异形触控单元，特别是开槽位置的异形触控单元，由于开槽是会切除触控膜层的一部分，从而导致开槽处的异形触控单元有可能是部分触控通道或全部触控通道被切断，从而导致该异形触控单元的触控功能较差甚至无触控功能。
为了实现异形触控单元的触控功能，本申请实施例设置连接第一异形触控电极块41或第一触控电极块11的第一异形触控引线43，以及连接第二异形触控电极块42或第二触控电极块21的第二异形触控引线44。第一异形触控引线43与第二异形触控引线44绝缘交叉形成异形触控补偿电容，以保证异形触控单元40的触控性能。
应当理解，本申请实施例中的异形触控单元40在开槽后若只剩余第一异形触控电极块41或第二异形触控电极块42。即只有第一触控电极10和第二触控电极20其中之一被切断或被切除，此情形下只需重新构建被切断或被切除的第一触控电极10或第二触控电极20即可。若第一触控电极10和第二触控电极20均被切断，则需要同时连通第一触控电极10和第二触控电极20。连通第一触控电极10或第二触控电极20的具体实现方式为新增相应的异形触控引线，即新增第一异形触控引线43或第二异形触控引线44，且第一异形触控引线43 沿第一方向延伸，第二异形触控引线44沿第二方向延伸，通过构建第一异形触控引线43和第二异形触控引线44，以实现第一方向上的第一触控电极10的连通和第二方向上的第二触控电极20的连通，第一异形触控引线43与第二异形触控引线44绝缘交叉形成异形触控补偿电容，即实现了异形触控单元40的触控功能。通过重新连通第一触控电极10和/或第二触控电极20，实现了第一方向和第二方向的触控通道的完整性，且实现了异形触控单元40的触控功能，提高了用户的触控体验。
本申请实施例提供的一种触控显示面板，通过在显示区内的异形触控单元内设置连接第一异形触控电极块或第一触控电极块的第一异形触控引线、连接第二异形触控电极块或第二触控电极块的第二异形触控引线，第一异形触控引线与第二异形触控引线绝缘交叉形成异形触控补偿电容，从而避免异形触控单元因开槽或边缘区切断而导致第一触控电极或第二触控电极被切断，即避免异形触控单元触控性能较差的情况，从而保证了异形触控单元的触控性能。
在本申请一些实施例中，异形触控单元40的设置位置可以不断开第一触控电极10和第二触控电极20，即，第一触控电极10和第二触控电极20为连续设置。具体的，异形触控单元40位于第一触控电极10和第二触控电极20的端部(例如通常位于显示面板的四角位置)。
如图1所示，异形触控单元40包括第一异形触控电极块41(图1中沿横向的电极块)和第二异形触控电极块42(图1中沿纵向的电极块)，第一异形触控引线43与第一异形触控电极块41电连接，第二异形触控引线44与第二异形触控电极块42电连接，第一异形触控引线43位于第一触控电极10的延长线上，或者第二异形触控引线44位于第二触控电极20的延长线上，又或者第一异形触控引线43位于第一触控电极10的延长线上且第二异形触控引线44位于第二触控电极20的延长线上。
在本申请另一些实施例中，该异形触控单元仅包括第一异形触控电极块41和第二异形触控电极块42其中之一。当异形触控单元仅包括第一异形触控电极块41时(此时该异形触控单元沿第二方向的异形电极块均被切除)，第一异形触控引线43与第一异形触控电极块41电连接，与该异形触控单元相邻的第一触控单元30的第二触控电极块21与第二异形触控引线44电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。当异形触控单元仅包括第二异形触控电极块42时(此时该异形触控单元沿第一方向的电极块均被切除)，与该异形触控单元相邻的第一触控单元30的第一触控电极块11与第一异形触控引线43电连接，第二异形触控引线44与第二异形触控电极块42电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。
通过第一异形触控引线41和第二异形触控引线42分别实现位于第一触控电极10和第二触控电极20的端部的异形触控单元40沿第一方向和第二方向的导电连通，且通过第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容，实现了该异形触控单元40的触控功能。
在一实施例中，异形触控单元40可以断开第一触控电极10和第二触控电极20至少其中之一，即异形触控单元40位于第一触控电极10和/或第二触控电极20内部位置。具体的，异形触控单元40为一个时，异形触控单元40断开第一触控电极10和/或第二触控电极20，异形触控单元40包括第一异形触控电极块41和/或第二异形触控电极块42，第一异形触控引线43与第一异形触控电极块41或第一触控电极块11连接，第二异形触控引线44与第二异形触控电极块42或第二触控电极块21连接，第一异形触控引线43与第二异形触控引线44绝缘交叉形成异形触控补偿电容。
如图2所示，当异形触控单元A为一个且隔断开第一触控电极10和第二触控电极20，即异形触控单元位于显示区域内(异形触控单元的四周存在其他第一触控单元30)。在本实施方式中，异形触控单元A包括第一异形触控电极块41和第二异形触控电极块42，第一异形触控引线43与第一异形触控电极块41电连接，第二异形触控引线44与第二异形触控电极块42电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。
在本申请另一实施例中，如图2中的异形触控单元40同时断开第一触控电极10和第二触控电极20，且该异形触控单元40仅包括第一异形触控电极块41或第二异形触控电极块42。下面以异形触控单元40仅包括第一异形触控电极块41为例进行说明，第一异形触控引线43与第一异形触控电极块41电连接，第二异形触控引线44与相邻的触控单元30的第二触控电极块21电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。异形触控单元40仅包括第二异形触控电极块42的情况与上述相似，即由第一异形触控引线43与相邻的触控单元30的第二触控电极块21电连接，第二异形触控引线44与第二异形触控电极块42电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。
在本申请另一实施例中，异形触控单元也可以仅断开第一触控电极10或第二触控电极20，即异形触控单元0位于第一触控电极10和第二触控电极20其中一条的端部且位于另一条的内部。如图2所示，异形触控单元B断开第一触控电极10，第一异形触控引线43与第一异形触控电极块41电连接，第二异形触控引线44与第二异形触控电极块42电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。
图2中仅示出了异形触控单元40断开第一触控电极10的一种情况，当异形触控单元40断开第二触控电极20时，第一异形触控引线43与第一异形触控电极块41电连接，第二异形触控引线44与第二异形触控电极块42电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。
应当理解，图2中仅示出了异形触控单元40同时包括第一异形触控电极块41和第二异形触控电极块42的情形，异形触控单元40亦可仅包括第一异形触控电极块41或第二异形触控电极块42时，以异形触控单元40仅包括第一异形触控电极块41且断开第一触控电极10为例，此时，第一异形触控引线43与第一异形触控电极块41电连接，第二异形触控引线44与相邻的触控单元30的第二触控电极块21电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。
如图3所示，异形触控单元可以为两个及两个以上且断开第一触控电极10和第二触控电极20至少其中之一。具体的，以异形触控单元为两个为例，如图3所示，异形触控单元C和D断开第一触控电极10，异形触控单元C和D分别同时包括第一异形触控电极块41和第二异形触控电极块42，通过一条第一异形触控引线43同时将两个第一异形触控电极块41连接起来，并通过两条第二异形触控引线44分别连接两个第二异形触控电极块42以将其引出，从而，一条第一异形触控引线43与两条第二异形触控引线44相互绝缘且交叉设置而形成两个异形触控补偿电容。
应当理解，类似的，当两个异形触控单元40断开第二触控电极20时，两条第一异形触控引线43分别连接两个第一异形触控电极块41以将其引出，并通过一条第二异形触控引线44将两个第二异形触控电极块42连接起来，从而，一条第一异形触控引线43与两条第二异形触控引线44相互绝缘并交叉设置而形成两个异形触控补偿电容。
还应当理解，图3中仅示出了两个异形触控单元40都包括第一异形触控电极块41和第二异形触控电极块42的情形，当异形触控单元40仅包括第一异形触控电极块41或第二异形触控电极块42时，以异形触控单元40仅包括第一异形触控电极块41且断开第一触控电极10为例，此时，第一异形触控引线43与第一异形触控电极块41电连接，第二异形触控引线44与相邻的触控单元30的第二触控电极块21电连接，第一异形触控引线43与第二异形触控引线44相互绝缘且交叉设置而形成异形触控补偿电容。
在本申请一实施例中，当异形触控单元为两个以上时，以异形触控单元断开第一触控电极10为例进行说明。通过设置一条第一异形触控引线43将该相邻的多个异形触控单元两端的第一异形触控电极块41电连接，并设置多条第二异形触控引线44将该相邻的多个异形触控单元的第二异形触控电极块42分别电连接，一条第一异形触控引线43与多条第二异形触 控引线44相互绝缘且交叉设置而形成多个异形触控补偿电容。应当理解，该相邻的多个异形触控单元中有可能存在不包括第二异形触控电极42的异形触控单元40，此时，设置多条第二异形触控引线44，使其分别连接于位于所述多个异形触控单元之间的多个第一触控单元的第二触控电极，多条第二异形触控引线44与第一异形触控引线43相互绝缘且交叉设置而形成该不包括第二异形触控电极42的异形触控单元40的异形触控补偿电容。
在本申请一实施例中，如图3所示，本申请实施例通过设置第一异形触控引线43与第二异形触控引线44连通断开的第一触控电极10或第二触控电极20来实现异形触控单元40的触控功能，并且第一异形触控引线43与第二异形触控引线44的绝缘交叉点位于异形触控单元40的信号引出线位置。如图3中的位置E，通过将第一异形触控引线43与第二异形触控引线44的绝缘交叉点(在触控显示面板上的正投影交点)设置在信号引出线位置，从而避免第一触控电极10或第二触控电极20中的电容值叠加过多而导致部分电容值过大引起的触控均一性较差的问题，提高了触控体验。应当理解，本申请实施例可以根据实际应用场景的需求而选取第一异形触控引线43与第二异形触控引线44的绝缘交叉点的具体位置，只要所选取的具体位置能够保证第一触控电极10和第二触控电极20中各处的触控均一性即可，本申请实施例对于第一异形触控引线43与第二异形触控引线44的绝缘交叉点的具体位置不做限定。

在一实施例中，如图2所示，第一异形触控引线43与第二异形触控引线44的绝缘交叉点可以位于显示区1内。开槽后的异形触控单元40的第一异形触控电极块41或者是第二异形触控电极块42可能部分被切除掉。此时，只需通过第一异形触控引线43和第二异形触控引线44连通第一触控电极10或第二触控电极20，并且设置第一异形触控引线43与第二异形触控引线44的绝缘交叉点位于显示区1内，即第一异形触控引线43与第二异形触控引线44在触控显示面板上的正投影相交于显示区1内，例如图2中第一异形触控引线43与第二异形触控引线44的绝缘交叉位置，通过将第一异形触控引线43与第二异形触控引线44的 绝缘交叉点设置在显示区1内，保证第一异形触控电极块41和第二异形触控电极块42的面积，从而可以提高该异形触控单元40的触控性能，提高触控体验。应当理解，本申请实施例可以根据实际应用场景的需求而选取第一异形触控引线43与第二异形触控引线44的绝缘交叉点的具体位置，只要所选取的交点的具体位置能够保证异形触控单元40的触控性能即可，本申请实施例对于第一异形触控引线43与第二异形触控引线44的绝缘交叉点的具体位置不做限定。
在本申请一实施例中，第一异形触控电极块41和第二异形触控电极块42的面积相等。通过将异形触控单元40的第一异形触控电极块41和第二异形触控电极块42的面积设置为相等或相近，从而保证了异形触控单元40的触控性能。应当理解，本申请实施例可以根据实际应用场景的需求而选取第一异形触控电极块41和第二异形触控电极块42的面积关系，例如只需设置第一异形触控电极块41和第二异形触控电极块42的面积大于某一面积阈值以保证其触控性能，只要所选取的第一异形触控电极块41和第二异形触控电极块42的面积关系能够保证异形触控单元40的触控性能即可，本申请实施例对于第一异形触控电极块41和第二异形触控电极块42的面积关系不做限定。

在本申请一实施例中，上述第一方向与第二方向可以垂直。通过设置相互垂直的第一方向和第二方向，相当于在触控面板上建立了相互垂直的两个坐标轴(即第一方向和第二方向)，这样能够更为方便和准确的获知用户触控的具体位置，实现准确而快速的触控反应，提高触控体验。应当理解，本申请实施例可以根据实际应用场景的需求而选取第一方向和第二方向的夹角大小，只要所选取的夹角大小能够保证准确且快速的实现触控定位即可，本申请实施例对于第一方向和第二方向的具体夹角大小不做限定。
本申请一实施例还提供了一种触控显示装置，包括如上任一实施例中的触控显示面板。 本申请实施例提供的一种触控显示装置，通过在显示区内的异形触控单元内设置连接第一异形触控电极块或第一触控电极块的第一异形触控引线、连接第二异形触控电极块或第二触控电极块的第二异形触控引线，并且第一异形触控引线与第二异形触控引线绝缘交叉形成异形触控补偿电容，从而避免异形触控单元因开槽切断而导致第一触控电极或第二触控电极被切断所带来的触控性能较差的情况，从而保证了触控性能。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换等，均应包含在本申请的保护范围之内。
