具体实施方式
下面将结合附图，对本公开一些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公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。

本文参照作为理想化示例性附图的剖视图和/或平面图描述了示例性实施方式。在附图中，为了清楚，放大了层和区域的厚度。因此，可设想到由于例如制造技术和/或公差引起的相对于附图的形状的变动。因此，示例性实施方式不应解释为局限于本文示出的区域的形状，而是包括因例如制造而引起的形状偏差。例如，示为矩形的蚀刻区域通常将具有弯曲的特征。因此，附图中 所示的区域本质上是示意性的，且它们的形状并非旨在示出设备的区域的实际形状，并且并非旨在限制示例性实施方式的范围。
随着显示技术的发展，单元柔性多层(Flexible Multiple Layer on Cell，FMLOC)技术正逐步应用在有机发光二极管(Organic Light Emitting Diode，OLED)显示装置中，单元上柔性多层技术FMLOC将显示结构和触控结构集成在一起，可以满足显示技术轻薄、可折叠、窄边框的发展趋势。
目前，随着柔性产品的出现，在相关技术中，触控技术采用金属网格(Metal Mesh)结构设计，金属网格具有电阻小、厚度小和反应速度快等优点，出于产品较薄以及电阻电容负载(RC Loading)加大的考虑，将单层金属网格(Metal Mesh)设计为FMLOC结构。
在一些实施例中，如图1A所示，触控显示装置1000包括堆叠设置的显示面板10和触控结构层20，触控结构层20位于显示面板10的显示面一侧，其中，显示面板10包括阳极层，触控结构层20包括金属网格。
参照图1B和图1C，以触控显示装置1000为手机为例，手机屏幕为刘海屏，刘海屏即为在屏幕正上方有一个非显示区BB(刘海区域)，除刘海区域外为显示区AA，在该刘海区域内设置有摄像头等器件，该区域需要打通孔，以在通孔内放置摄像头，用于实现触控的金属网格分布在显示区和非显示区，其中，金属网格由多条金属线201’构成，例如，如图1C所示，多条金属线围合成一个金属网格，金属网格的形状呈六边形或四边形。摄像头孔周边由于工艺条件限制，位于孔周围的金属线201’的实际线宽相对于设计线宽存在偏差，为避免这种线宽偏差做了色散补偿设计，示例性地，在靠近通孔的区域，金属线201’的线宽较大，在远离通孔的区域，金属线201’的线宽较小，如图1C所示，显示区AA中的金属网格没有做色散补偿设计，补偿值ΔCD1为0，非显示区BB中的金属网格做了色散补偿设计，补偿值ΔCD2为x，显示区AA中的金属网格的线宽小于非显示区BB中的金属网格的线宽。
然而，在暗态强反射光条件下，色散补偿设计的区域和没有色散补偿的区域会出现亮暗分区且有明显的边界光学不良问题。这种亮暗分区有明显边界的光学不良是由于侧视角下金属网格遮挡光线，阳极反射的光线量不同引起的，在与触控显示面板所在的平面呈45°一侧方向上向触控显示面板上打光，在与触控显示面板所在的平面呈45°的另一侧方向上人眼去观测，可见亮暗分区边界的光学不良现象。如图2A和图2B所示，图2A为没有光学补偿的区域(即显示区)呈现的反射情况，例如图2A表示光线穿过图1C的DD处的触控线的路径图；图2B为具有光学补偿的区域(即非显示区BB)呈现的反 射情况，例如图2B表示光线穿过图1C的CC处的触控线的路径图；根据图2A和图2B可得，没有光学补偿的区域(即显示区AA)的反射量大于具有光学补偿的区域(即非显示区BB)，这是由于具有光学补偿的区域的金属线201’较宽，遮挡了部分从外界射向阳极层的光，从而造成阳极层反射光也减少，在金属网格的线宽较大的区域的阳极层反射光小于金属网格的线宽较小的区域的阳极层反射光，因此，触控显示面板中表现为亮暗分区不良，影响显示效果，从而影响用户的使用体验。
为了解决这一问题，本公开的实施例提供了一种触控显示装置1000。该触控显示装置1000可以是具有触控功能和图像显示功能的产品。例如，触控显示装置可以是具有触控功能的显示器，电视，个人计算机，笔记本电脑，广告牌，数码相框，具有显示功能的激光打印机，电话，手机，数码相机，电子画屏，便携式摄录机，取景器，监视器，导航仪，车辆，大面积墙壁或信息查询设备(如电子政务、银行、医院、电力等部门的业务查询设备)，车载显示器等，本公开实施例对触控显示装置的用途不作限制。此外，该触控显示装置可以是可卷曲的或者可弯曲的柔性触控显示装置，也可以为平板状的刚性触控显示装置。又如，触控显示装置1000还可以是触控显示面板100(也可以称为触控显示屏)。又如，触控显示装置1000除了触控显示面板100之外，还可以包括其他电子器件，例如触控芯片和主板等。其中，触控芯片与触控显示面板耦接，被配置为基于触控显示面板提供的触摸信号，确定触摸位置(例如触摸坐标)。主板与触控显示面板耦接，被配置为基于触控芯片确定的触摸位置，向触控显示面板输出相应的图像数据。
以下对本公开提供的一种触控显示面板100及触控显示装置1000分别进行介绍。
在本公开中，图3A、图3B为触控显示面板100的结构图，图7A、图9A、图9B和图9C均为触控显示面板100的局部放大图，图4A～图4C，图5A～图5C，图6A～图6C、图8A和图8B为图7A、图9A、图9B和图9C的进一步放大图，图7B和图7C为图7A中在EE处的截面图，为了方便对触控显示面板100的描述，图7B和图7C仅示意出触控结构层的示意图。
本公开的一些实施例提供了一种触控显示面板100，如图3A所示，图3A为一些实施例提供的触控显示面板100的侧视图，图3B为图3A的俯视图。参见图3A和图3B，触控显示面板100包括显示面板10和设置于显示面板10一侧的触控面板20’，触控面板20’包括触控结构层20，触控结构层20包括多条触控线201，多条触控线201定义出多个触控网格202。需要说明的是， 在图3B中仅示意出一个局部区域内的触控线，实际上，触控结构层20分布在触控显示面板100的整个平面区域中。
示例性地，参见图3A，显示面板10是具有显示功能的屏幕，可以与上文中的主板耦接，被配置为接受主板发送的图像数据，并显示相应的图像。例如，显示面板10可以是自发光显示面板，例如可以为OLED(Organic Light Emiing Diode，有机发光二极管)显示面板、QLED(Quantum Dot Light Emiing Diodes，量子点发光二极管)显示面板、微LED(包括：Mini LED迷你发光二极管或Micro LED微型发光二极管)显示面板等，当触控显示装置1000中的显示面板10为液晶显示面板时，触控显示装置1000为液晶触控显示装置1000；当触控显示装置1000中的显示面板10为自发光显示面板时，触控显示装置1000为自发光触控显示装置1000。
显示面板10具有沿显示面板10的厚度方向相对的显示面和非显示面。用户可以面朝显示面板10的显示面观看画面。也就是说，显示面板10的显示面远离非显示面的一侧为供用户观看的一侧，下文将这一侧称为显示面板10的显示侧。
继续参见图3A，触控结构层20被配置为提供触摸信号，触摸信号可以反映出用户在显示面板10上的触摸位置。触控结构层20可以与上文中的触控芯片耦接，以将触控信号提供给触控芯片。
在一些可能的实施方式中，触控结构层20可以位于显示面板10的显示侧。触控结构层20可以是独立于显示面板10的一个部件；示例性地，显示面板10与触控结构层20二者均单独形成，之后二者通过诸如光学胶(Optically Clear Adhesive，简称OCA)之类的粘合剂粘合在一起。触控结构层20也可以是集成在显示面板10上的结构。示例性地，以显示面板10作为基底，在显示面板10的显示面上形成触控结构层20，此时触控结构层20与显示面板10的显示面直接接触。例如，显示面板10为OLED显示面板或QLED显示面板，该显示面板10可以包括显示基板和覆盖在显示基板上的封装层；触控结构层20可以形成在封装层上。示例性地，触控结构层20与显示面板10的显示面之间也可以设置有其他功能层。
在另一些可能的实施方式中，触控结构层20也可以设置于显示面板10的内部。示例性地，显示面板10包括相对的第一基板和第二基板，触控结构层20可以位于第一基板和第二基板之间。
在电容式触控技术的应用中，可以将用于实现触摸感测的多个膜层结构层叠设置形成触控层，触控层中包括多个触控电极。电容式触控技术可以分为 自容式触控技术和互容式触控技术等。当该触控层应用自容式触控技术时，触控电极与地构成电容，即自电容。当手指触摸触控显示装置时，手指的电容将会叠加到触控电极上，使触控电极与地构成的电容发生变化。根据触摸前后多个触控电极与地构成的电容的变化量，便可以确定触摸点的坐标，实现触摸感测。当该触控层应用互容式触控技术时，多个触控电极可以分为触控驱动电极和触控感测电极，触控驱动电极可以被配置为传输触控驱动信号，触控感测电极可以被配置为传输触控感测信号，从而在触控驱动电极和触控感测电极之间形成稳定电容。当手指触碰到触控显示装置时，会影响到触摸位置附近的触控驱动电极和触控感测电极之间的耦合，从而改变这两个触控电极之间的电容，同样根据触摸前后驱动电极和感测电极间电容的变化量，可以确定触摸点的坐标。
为了表述的简便，以下以触控显示装置应用互容式触控技术，且触控层设置在显示面板出光面的一侧，显示面板中最靠近触控层的一个膜层用做触控层的基底层为例，对本公开的方案进行解释说明。
本公开的一些实施例提供一种触控结构层，可以应用于上述的触控显示装置中，也可以应用于其它的触控装置中，对此不作过多限制。
显示面板10可以包括多个子像素，每个子像素包括相互耦接的像素驱动电路和发光器件，像素驱动电路被配置为驱动发光器件发光。像素驱动电路可以包括多个晶体管和电容器等电子器件元件。例如，像素驱动电路均可以包括三个晶体管和一个电容器，构成3T1C(即一个驱动晶体管、两个开关晶体管和一个电容器)。还可以包括三个以上的晶体管和至少一个电容器，如4T1C(即一个驱动晶体管、三个开关晶体管和一个电容器)、5T1C(即一个驱动晶体管、四个开关晶体管和一个电容器)或7T2C(即一个驱动晶体管、六个开关晶体管和两个电容器)等。其中，晶体管可以为薄膜晶体管(Thin Film Transistor，简称TFT)、场效应晶体管(Metal Oxide Semiconductor，简称MOS)或其他特性相同的开关器件。发光器件可以是OLED或QLED。
为了实现上述子像素的结构，示例性地，参见图3A，显示面板10包括：依次层叠设置的基底11、像素驱动电路层12、发光器件层13和第一封装层14，其中发光器件层13包括阳极层131，第一封装层14可以为封装薄膜，也可以为封装基板。
上述基底11的结构可以根据实际需要选择设置。
例如，基底11可以为刚性基底。该刚性基底例如可以包括玻璃基底PMMA(Polymethyl methacrylate，聚甲基丙烯酸甲酯)。在此情况下，上述显示 面板10可以为刚性显示面板。
又如，基底11可以为柔性基底。该柔性基底例如可以包括PET(Polyethylene terephthalate，聚对苯二甲酸乙二醇酯)基底、PEN(Polyethylene naphthalate two formic acid glycol ester，聚萘二甲酸乙二醇酯)基底或PI(Polyimide，聚酰亚胺)基底。在此情况下，上述显示面板10可以为柔性显示面板。
在一些实施例中，触控显示面板100还包括位于显示面板10远离触控结构层20一侧的玻璃盖板15，以对显示面板10形成保护。
在一些实施例中，触控面板20’还包括第二封装层26，第二封装层26将触控结构层20包覆封装，以使触控结构层与外部隔绝。其中，第二封装层26的材料可以是氮化物、氧化物、氮氧化物、硝酸盐、碳化物或其任何组合等无机绝缘材料，当然，也可以是有机绝缘材料，例如，腈纶、六甲基二硅氧皖、聚丙烯酸酯类、聚碳酸脂类、聚苯乙烯等材料。
参照图3B，图3B为触控显示面板100的平面图，其中，触控显示面板100包括第一区101(触控区)和非触控区102，其中第一区101为触控显示面板100上用于显示画面的区域，同时第一区101也能实现触控，对应图1B中的显示区AA。非触控区102嵌设在第一区101内部，例如，在一些实施例中，触控显示面板10为刘海屏，在刘海区域不显示画面，刘海区域为非触控区102，第一区101半包围非触控区102，其中，非触控区102包括第二区1021以及通孔区域1023，在通孔区域1023设置有摄像头等器件。
其中，如图4A和图4B所示，多条触控线201包括位于第一区101的多条第一触控线2011和位于第二区1021的多条第二触控线2012；多条第一触控线2011中至少一条第一触控线2011的线宽小于多条第二触控线2012中至少一条第二触控线2012的线宽。这是由于在通孔区域1023的周边会受到工艺条件限制，触控线201的线宽在通孔区域1023的周边会发生偏差，为避免触控线201的线宽的偏差做了光学补偿设计，使得多条触控线201中靠近通孔区域1023的触控线201的线宽越大，而第二区1021相较于第一区101更靠近通孔区域1023的位置，因此，多条第一触控线2011中至少一条第一触控线2011的线宽小于多条第二触控线2012中至少一条第二触控线2012的线宽，具体参照前边的介绍。
如图4A、图4B和图4C所示，第一触控线2011的线宽为L1，第二触控线2012的线宽为L2，第三触控线2013的线宽为L3，从图中可以得出，L1＜L2＜L3，其中，如前所述，触控线201的线宽越宽，从外界进入的入射光中 被触控线201遮挡的越多，侧视角下遮挡的阳极层反射光越多，因此，表现为亮暗分区不良，影响显示效果。
示例性地，触控显示面板100可以是矩形，也可以是圆角矩形等与矩形类似的形状。
在一些实施例中，本公开提供的触控显示面板100中，第一区101和第二区1021的反射率相等，反射率为，来自触控结构层20一侧的入射光线穿过多条触控线201照射到阳极层131上，再由阳极层131反射至触控结构层20一侧的光线与入射光线的比例。光线路径示意图可以参照图2A和图2B。
可以理解的是，在第一区101和第二区1021反射率相等的情况下，反射量也相同，因此，即便整个触控显示面板100中不同区域的触控线201的线宽不同，由于第一区101和第二区1021的反射率设置为相等，也即入射光线穿过多条触控线201照射到阳极层131上，再由阳极层131反射至触控结构层20一侧的光线与入射光线的比例相等，触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在一些实施例中，继续参照图3B，触控显示面板100还包括第三区1022。其中，第三区1022为非触控区102中的一部分区域，且非触控区102包括两个通孔区域1023，第三区1022位于非触控区102的两个通孔区域1023之间，非触控区102中除通孔区域1023和第三区1022之外的区域为第二区1021。
其中，如图4C所示，多条触控线201还包括位于第三区1022的多条第三触控线2013，多条第三触控线201中至少一条第三触控线2013的线宽大于第二触控线2012中至少一条第二触控线2012的线宽。
结合上述介绍及图4A和图4B所示可得，多条第一触控线2011中至少一条第一触控线2011的线宽小于多条第二触控线2012中至少一条第二触控线2012的线宽，多条第二触控线2012中至少一条第二触控线2012的线宽小于多条第三触控线2013中至少一条第三触控线2013的线宽。这是由于在通孔区域1023的周边会受到工艺条件限制，触控线201的线宽在通孔区域1023的周边会发生偏差，为避免触控线201的线宽的偏差做了光学补偿设计，使得多条触控线201中靠近通孔区域1023的触控线201的线宽越大，而第三区1022相较于第一区101和第二区1021更靠近通孔区域1023的位置，因此，多条第一触控线2011中至少一条第一触控线2011的线宽小于多条第二触控线2012中至少一条第二触控线2012的线宽，多条第二触控线2012中至少一条第二触控线2012的线宽小于多条第三触控线2013中至少一条第三触控线 2013的线宽，具体参照前边的介绍。
在一些实施例中，第三区1022的反射率与第一区101和第二区1021的反射率相等。可以理解的是，在第一区101、第二区1021和第三区1022的反射率相等的情况下，反射量也相同，因此，即便整个触控显示面板100中不同区域的触控线201的线宽不同，由于第一区101、第二区1021和第三区1022的反射率相等，也即入射光线穿过多条触控线201照射到阳极层131上，再由阳极层131反射至触控结构层20一侧的光线与入射光线的比例相等，进而触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
以下介绍使得触控显示面板100的第一区101、第二区1021和第三区1022的反射率相等的几种实施例。
在一种实现方式中，参照图5A、图5B和图5C所示，图5A、图5B和图5C分别表示第一区101、第二区1021和第三区1022的触控线的排布结构图，多条触控线201中的至少一部分触控线201上设置有断口2010，其中，一条触控线201上设置有断口2010是指该触控线201从断口2010处断开，即触控线201的一部分在断口2010处缺失，在断口2010处，从外界射入的光线没有被遮挡，光线能够穿过断口2010入射到阳极层131上，从而能够提高光线的反射率。
如图5D和图5E所示，图5D表示在触控线201没有设置断口2010的位置处，光线的路径示意图，图5E表示在触控线201设置断口2010的位置处，光线的路径示意图，可见，在断口2010处，从外界射入的光线没有被遮挡，光线能够穿过断口2010入射到阳极层131上，从而能够提高光线的反射率。
在一些实施方式中，第一区101的断口率小于第二区1021的断口率，第二区1021的断口率小于第三区1022的断口率；其中，断口率为，一区域中多条触控线201中设置有断口2010的触控线201占该区域中所有触控线201的比值。参照图4A、图4B和图4C所示，由于第一区101、第二区1021和第三区1022的触控线201的线宽关系为L1＜L2＜L3，即第三触控线2013的线宽最宽，遮挡光线最多，因此将第一区101、第二区1021和第三区1022的断口率的关系如上述设置，可以保证第一区101、第二区1021和第三区1022的反射率相等，触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在一些实施例中，继续参照图5A、图5B和图5C，第一区101中断口2010的密度，小于第二区1021中断口2010的密度，第二区1021中断口2010 的密度，小于第三区1022中断口2010的密度。
需要说明的是，断口2010的密度反应各个区域的疏密程度或断口2010数量，通过设置第一区101中断口2010的密度，小于第二区1021中断口2010的密度，第二区1021中断口2010的密度，小于第三区1022中断口2010的密度，可以理解为第一区101中断口2010排布较第二区1021中断口2010排布稀疏，第二区1021中断口2010排布较第三区1022中断口2010排布稀疏，同样，也可以理解为第一区101中断口2010的数量，小于第二区1021中断口2010的数量，第二区1021中断口2010的数量，小于第三区1022中断口2010的数量，因此将第一区101、第二区1021和第三区1022的断口2010的密度关系如上述设置，可以保证第一区101、第二区1021和第三区1022的反射率相等，进而触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在另一些实施例中，第一区101中断口2010的大小，小于第二区1021中断口2010的大小，第二区1021中断口2010的大小，小于第三区1022中断口2010的大小。
需要说明的是，断口2010的大小反应断口2010的面积尺寸，第一区101中断口2010的大小，小于第二区1021中断口2010的大小，第二区1021中断口2010的大小，小于第三区1022中断口2010的大小，可以理解为，第一区101中断口2010的面积尺寸，小于第二区1021中断口2010的面积尺寸，第二区1021中断口2010的面积尺寸，小于第三区1022中断口2010的面积尺寸，因此将第一区101、第二区1021和第三区1022的断口2010的面积尺寸关系如上述设置，可以保证第一区101、第二区1021和第三区1022的反射率相等，进而触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在一些实施例中，在第一区101、第二区1021和第三区1022中，断口2010的设置方式也可以为上述两种实施例的结合，即第一区101中断口2010的密度，小于第二区1021中断口2010的密度，第二区1021中断口2010的密度，小于第三区1022中断口2010的密度；并且第一区101中断口2010的大小，小于第二区1021中断口2010的大小，第二区1021中断口2010的大小，小于第三区1022中断口2010的大小。示例性地，上述两种实施例的结合，将第一区101、第二区1021和第三区1022的断口2010的密度和面积尺寸关系如上述设置，可以保证第一区101、第二区1021和第三区1022的反射率相等，进而触控显示面板100的显示画面不会表现为亮暗分区不良，可以 减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在一些实施例中，第一区101的断口率为20％，第二区1021的断口率为23％～27％，第三区1022的断口率为28％～32％。
示例性地，例如，第一区101的断口率为20％，第二区1021的断口率为23％，第三区1022的断口率为28％，又例如，第一区101的断口率为20％，第二区1021的断口率为25％，第三区1022的断口率为30％，再例如，第一区101的断口率为20％，第二区1021的断口率为27％，第三区1022的断口率为32％等，上述关于不同区域设置不同的断口率中，第一区101的断口率小于第二区1021的断口率，第二区1021的断口率小于第三区1022的断口率，通过这样的设置，可以让更多的来自触控结构层20一侧的入射光线穿过多条触控线201的多个断口2010处，照射到阳极层131上，再由阳极层131反射至触控结构层20一侧，增强反射率，不同的断口率可以改变反射率，在取得上述示例中不同区域对应的断口率时，能够使得第一区101、第二区1021和第三区1022的反射率一致，最终改善区域光学不良的问题。
在另一种实现方式中，如图6A、图6B和图6C所示，图6A、图6B和图6C分别表示第一区101、第二区1021和第三区1022的触控线的结构图，多条触控线201中的至少一部分触控线201上设置有开孔2020，其中，开孔2020为在触控线201上设置的孔，即触控线201的一部分在开孔2020处缺失，在开孔2020处，从外界射入的光线没有被遮挡，光线能够穿过开孔2020入射到阳极层131上，从而能够提高光线的反射率。
开孔2020与断口2010的区别是，在开设有开孔2020的触控线201中，该触控线201依旧为连接状态，在设置有断开的触控线201中，该触控线201被断开，一分为二，这两种设计均能提高外界入射的光线射入阳极层131上的入射率。
如图6D和图6E所示，图6D表示在触控线201没有设置开孔2020的位置处，光线的路径示意图，图6E表示在触控线201设置开孔2020的位置处，光线的路径示意图，可见，在开孔2020处，从外界射入的光线没有被遮挡，光线能够穿过开孔2020入射到阳极层131上，从而能够提高光线的反射率。
在一些实施方式中，第一区101的开孔率小于第二区1021的开孔率，第二区1021的开孔率小于第三区1022的开孔率；其中，开孔率为，一区域中多条触控线201中设置有开孔2020的触控线201占该区域中所有触控线201的比值。参照图4A、图4B和图4C所示，由于第一区101、第二区1021和第三区1022的触控线201的线宽关系为L1＜L2＜L3，即第三触控线2013的 线宽最宽，遮挡光线最多，因此将第一区101、第二区1021和第三区1022的断口率的关系如上述设置，可以保证第一区101、第二区1021和第三区1022的反射率相等，触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在一些实施例中，第一区101中开孔2020的密度小于第二区1021中开孔2020的密度，第二区1021中开孔2020的密度小于第三区1022中开孔2020的密度。
需要说明的是，开孔2020的密度反应各个区域的疏密程度或开孔2020数量，通过设置第一区101中开孔2020的密度，小于第二区1021中开孔2020的密度，第二区1021中开孔2020的密度，小于第三区1022中开孔2020的密度，可以理解为第一区101中开孔2020排布较第二区1021中开孔2020排布稀疏，第二区1021中开孔2020排布较第三区1022中开孔2020排布稀疏，同样，也可以理解为第一区101中开孔2020的数量，小于第二区1021中开孔2020的数量，第二区1021中开孔2020的数量，小于第三区1022中开孔2020的数量，因此将第一区101、第二区1021和第三区1022的开孔2020的密度关系如上述设置，可以保证第一区101、第二区1021和第三区1022的反射率相等，进而触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在另一些实施例中，第一区101中开孔2020的尺寸小于第二区1021中开孔2020的尺寸，第二区1021中开孔2020的尺寸小于第三区1022中开孔2020的尺寸。
需要说明的是，开孔2020的尺寸反应开孔2020的面积尺寸，第一区101中开孔2020的尺寸，小于第二区1021中开孔2020的尺寸，第二区1021中开孔2020的尺寸，小于第三区1022中开孔2020的尺寸，可以理解为，第一区101中开孔2020的面积尺寸，小于第二区1021中开孔2020的面积尺寸，第二区1021中开孔2020的面积尺寸，小于第三区1022中开孔2020的面积尺寸，因此将第一区101、第二区1021和第三区1022的开孔2020的面积尺寸关系如上述设置，可以保证第一区101、第二区1021和第三区1022的反射率相等，进而触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在一些实施例中，在第一区101、第二区1021和第三区1022中，开孔2020的设置方式也可以为上述两种实施例的结合，即第一区101中开孔2020的密度，小于第二区1021中开孔2020的密度，第二区1021中开孔2020的 密度，小于第三区1022中开孔2020的密度；并且第一区101中开孔2020的尺寸，小于第二区1021中开孔2020的尺寸，第二区1021中开孔2020的尺寸，小于第三区1022中开孔2020的尺寸。示例性地，上述两种实施例的结合，将第一区101、第二区1021和第三区1022的开孔2020的密度和面积尺寸关系如上述设置，可以保证第一区101、第二区1021和第三区1022的反射率相等，进而触控显示面板100的显示画面不会表现为亮暗分区不良，可以减少反光结构的可视化风险，能够提升触控显示面板100的显示效果。
在一些实施例中，第一区101的开孔率为20％，第二区1021的开孔率为23％～27％，第三区1022的开孔率为28％～32％。
示例性地，例如，第一区101的开孔率为20％，第二区1021的开孔率为23％，第三区1022的开孔率为28％，又例如，第一区101的开孔率为20％，第二区1021的开孔率为25％，第三区1022的开孔率为30％，再例如，第一区101的开孔率为20％，第二区1021的开孔率为27％，第三区1022的开孔率为32％等，上述关于不同区域设置不同的开孔率中，第一区101的开孔率小于第二区1021的开孔率，第二区1021的开孔率小于第三区1022的开孔率，通过这样的设置，可以让更多的来自触控结构层20一侧的入射光线穿过多条触控线201的多个开孔2020处，照射到阳极层131上，再由阳极层131反射至触控结构层20一侧，增强反射率，不同的开孔率可以改变反射率，在取得上述示例中不同区域对应的开孔率时，能够使得第一区101、第二区1021和第三区1022的反射率一致，最终改善区域光学不良的问题。
在一些实施例中，开孔2020在显示面板10上的正投影的形状可以为圆形、矩形或椭圆。
示例性地，开孔2020在显示面板10上的正投影的形状为圆形，矩形和椭圆等，这里对形状不作限定。其中，在第一区101、第二区1021和第三区1022上设置的开孔2020的最大尺寸对应小于第一触控线2011、第二触控线2012和第三触控线2013的线宽。
在再一种实现方式中，如图6A～图6C所示，多条触控线201中的至少一部分触控线201上设置有开孔2020，至少另一部分触控线201上设置有断口2010，且第一区101的断口率小于第二区1021的断口率，第二区1021的断口率小于第三区1022的断口率，和/或，第一区101的开孔率小于第二区1021的开孔率，第二区1021的开孔率小于第三区1022的开孔率。示例性地，第一区101的断口率与开孔率之和，小于第二区1021的断口率与开孔率之和，且小于第三区1022的断口率与开孔率之和，在各区域中，对断口2010的密 度和大小，以及开孔2020的密度和尺寸设置不设限，只要能满足使得第一区101、第二区1021和第三区1022的反射率相等即可。
在又一种实现方式中，如图6F所示，多条触控线201中的至少部分触控线201为金属触控线201a，另一部分触控线201为透明导电触控线201b；在图6F中，以无图案填充的触控线作为透明导电触控线201b，有图案填充的触控线作为金属触控线201a。第一区101中透明导电触控线201b占多条第一触控线201的比值，小于第二区1021中透明导电触控线201b占多条第二触控线201的比值；第二区1021中透明导电触控线201b占多条第二触控线201的比值，小于第三区1022中透明导电触控线201b占所述多条第三触控线201的比值。
在上述实施例中，透明导电触控线201b的透过率较金属触控线201a的透过率较高，因此，一区域中，透明导电触控线201b占多条第一触控线201的比值越大，则一区域的整体透过率越高，其中，透过率为，一区域中来自触控结构层20一侧的入射光线中，穿过多条触控线201的照射到阳极层上的入射量与整个入射总量的比值。
在一些示例中，金属触控线201a的材料为镁铝合金(MgAl)和锂铝合金(LiAl)等合金或者镁(Mg)、铝(Al)、锂(Li)和银(Ag)，透明导电触控线201b的材料为氧化铟锡(ITO)、氧化铟锌(IZO)、氧化铟镓(IGO)、氧化镓锌(GZO)、氧化锌(ZnO)、氧化铟(In 2O 3)、氧化铝锌(AZO)和碳纳米管。
示例性地，第一区101的透过率小于第二区1021的透过率，第二区1021的透过率小于第三区1022的透过率，通过设置触控线201材质的比例来改变各区域的透过率，进而增强反射率，使得第一区101、第二区1021和第三区1022的反射率一致，最终改善区域光学不良的问题，从而增强触控显示面板100的显示效果。
如图6F所示，在一种实现方式中，多条触控线201中的至少一部分触控线201上设置有开孔2020，至少另一部分触控线201上设置有断口2010，且多条触控线201中的至少部分触控线201为金属触控线201a，另一部分触控线201为透明导电触控线201b，也就是说可以将触控线201上设置有开孔2020、触控线201上设置有断口2010，触控线201采用不同材料等多种方式自由组合，只要能满足使得第一区101、第二区1021和第三区1022的反射率相等即可。
在一些实施例中，第一区101为触控区，第二区1021和所述第三区1022 为非触控区；多条触控线201中，位于第一区101的多条触控线201，和位于第二区1021和第三区1022的多条触控线201之间断开。
示例性地，第一区101为触控显示面板100上用于显示画面的区域，且能实现触控，非触控区102不用于显示画面，不需要触控功能，第一区101和非触控区102之间可以不存在电性连接关系，也即二者之间电绝缘，所以，在设置位于第一区101和位于非触控区102的多条触控线201时，处于第一区101和非触控区102边界的多条触控线201之间可以断开连接，这样多条触控线中的断口密度可以进一步扩大。
在一些实施例中，在位于第一区101的多条触控线201，和位于第二区1021和第三区1022的多条触控线201之间断开的情况下，第一区101的断口率为20％，非触控区102中第二区1021的断口率为25％～40％，非触控区102中第三区1022的断口率为30％～50％。
示例性地，例如，第一区101的断口率为20％，第二区1021的断口率为25％，第三区1022的断口率为30％，又例如，第一区101的断口率为20％，第二区1021的断口率为30％，第三区1022的断口率为40％，再例如，第一区101的断口率为20％，第二区1021的断口率为40％，第三区1022的断口率为50％等，上述关于不同区域因第一区101和非触控区102边界的多条触控线201之间可以断开连接，对应断口率的不同，其中，第一区101的断口率小于第二区1021的断口率，第二区1021的断口率小于第三区1022的断口率，通过这样的设置，可以让更多的来自触控结构层20一侧的入射光线穿过多条触控线201的多个断口2010处，照射到阳极层131上，再由阳极层131反射至触控结构层20一侧，增强反射率，不同的断口率可以改变反射率，在取得上述示例中不同区域对应的断口率时，能够使得第一区101、第二区1021和第三区1022的反射率一致，最终改善区域光学不良的问题，从而增强触控显示面板100的显示效果。
在一些实施例中，参照图7A所示，触控结构层20包括第一触控结构层21和第二触控结构层22，第一触控结构层21和第二触控结构层22的相对位置可以互换，例如第一触控结构层21位于第二触控结构层22远离显示面板一侧，或者第一触控结构层21位于第二触控结构层22靠近显示面板一侧，图7A示意出第二种情况。触控结构层20包括多个触控子电极TR，第一触控结构层21包括沿第一方向X布置的多个第一触控子电极213以及多个第一连接电极212，多个第一触控子电极213和多个第一连接电极212一一交替分布且依次电连接，形成沿第一方向X延伸的多条第一触控电极210；第一触 控结构层21还包括沿第二方向Y依次布置且等间隔布置的多个第二触控子电极211，第二触控结构层22包括沿第二方向Y布置的多个第二连接电极214，且多个第二触控子电极211和多个第二连接电极214一一交替分布且依次电连接，形成沿第二方向Y延伸的第二触控电极220；其中，第一方向X与第二方向Y相交，多个第一触控子电极213、多个第一连接电极212、多个第二触控子电极211和所述多个第二连接电极214由多条触控线201构成。
示例性地，图7A示出了本公开至少一实施例提供的触控结构层20的结构图。如图7A所示，该触控结构层20包括沿第一方向X延伸的多条第一触控电极210和沿第二方向Y延伸的多条第二触控电极220。例如，在图7A中，该第一触控电极210为触控感测电极Tx，第二触控电极220为触控驱动电极Rx，本公开实施例并不对此进行限制，在其他示例中，第一触控电极210可以是触控驱动电极，第二触控电极220为触控感测电极。
在一些实施例中，每条第一触控电极210包括沿第一方向X依次布置且彼此连接的第一触控子电极213，每条第二触控电极220包括沿第二方向Y依次布置且彼此连接的第二触控子电极211。示例性地，如图7A所示，每个第一触控子电极213和第二触控子电极211的主体轮廓均为菱形。在其他示例中，该第一触控子电极213和第二触控子电极211也可以是其他形状，如三角形、条形等形状，这里并不对此形状作限定。
其中，在第一方向X上相邻的第一触控子电极213通过第一连接电极212电连接形成第一触控电极210，在第二方向Y上相邻的第二触控子电极211通过第二连接电极214电连接形成多条第二触控电极220。
在一些实施例中，多个第二连接电极214与多个第二触控子电极211为异层设置，可选的，多个第二连接电极214与多个第二触控子电极211的相对位置关系可以有两种情形，如图7B所示，多个第二连接电极214位于多个第二触控子电极211远离显示面板10一侧。或者，如图7C所示，多个第二连接电极214也可以位于多个第二触控子电极211靠近显示面板10一侧。
请参照图7B，图7B为图7A在EE处的截面图，图7B中示出了第二连接电极214位于第二触控子电极211远离显示面板10一侧的实施例，其中，第二连接电极214的两端均可以通过至少一个过孔P与第二触控子电极211电连接。
示例性地，第二连接电极214的两端可以通过两个过孔P与第二触控子电极211电连接，能够提升第二连接电极214与第二触控子电极211电连接的可靠性，同时可以降低第二连接电极214与第二触控子电极211的等效电 阻，从而降低显示面板的功耗，提升显示以及触控效果。
请参照图7C，图7C为图7A在EE处的另一些实施例的截面图，图7C中示出了第二连接电极214位于第二触控子电极211靠近显示面板10一侧的实施例，其中，第二连接电极214的两端均可以通过至少一个过孔P与第二触控子电极211电连接。
示例性地，第二连接电极214的两端可以通过两个过孔P与第二触控子电极211电连接，能够提升第二连接电极214与第二触控子电极211电连接的可靠性，同时可以降低第二连接电极214与第二触控子电极211的等效电阻，从而降低显示面板的功耗，提升显示以及触控效果。
继续参照图7B和图7C，触控面板20’还包括绝缘层23、缓冲层24和保护层25。其中，绝缘层23设置于第二连接电极214与第二触控子电极211之间，也即绝缘层23延展于第一触控结构层21与第二触控结构层22之间，绝缘层23能够使第一触控结构层21与第二触控结构层22之间绝缘。缓冲层24设置于触控结构层20靠近显示面板10一侧，触控结构层20与缓冲层24可以直接接触。保护层25设置于触控结构层20远离显示面板10的一侧，保护层25覆盖触控结构层20，主要用于保护触控结构层20，保护层25具有较高抗氧化性能的材料，能够阻挡外界的水和氧气，避免对触控结构层20造成腐蚀。
示例性地，请参见图3A，绝缘层23、缓冲层24和保护层25可以相当于前文中的第二封装层26，保护层25的材料可以参照上文中第二封装层26的介绍。例如，可以是氧化硅、氧化铝和氮硅化合物(SiNx)等无机绝缘材料，当然，也可以是有机绝缘材料，其中，保护层25与绝缘层23，二者的材料可以相同，也可以不同。
作为一种可能的设计，缓冲层24与绝缘层23，二者的材料可以相同，例如，氮化硅或聚酰亚胺(Polyimide)，也可以不同。
如图7A所示，每条第一触控电极210和每条第二触控电极220彼此绝缘交叉并在交叉处形成多个触控单元200，每个触控单元200包括在交叉处连接的两个第一触控电极部的各一部分以及在该交叉处连接的两个第二触控电极部的各至少一部分。如图8A所示，图8A中示出了一个触控单元200的放大结构图，从图8A中可知，多个第一触控子电极213、多个第一连接电极212、多个第二触控子电极211和多个第二连接电极214由多条触控线构成。其中，每个触控单元200包括彼此邻接的两个第一触控子电极213的各一半区域以及彼此邻接的两个第二触控子电极211的各一半区域，也即平均包括一个第 一触控子电极213的区域和一个第二触控子电极211的区域，每个触控单元200中的交汇点(也即第一连接电极212与第二连接电极214的交叉处)形成用于计算做坐标的基准点。当手指触摸到触摸屏时，影响了触摸点附近第一触控子电极213和第二触控子电极211之间的耦合，从而改变了这两个电极之间的互容量。触控感测信号根据触摸屏电容变化量而改变，由此可以基于基准点计算处每一个触摸点的坐标。例如，每个触控单元200的面积与人的手指接触触控显示面板100的面积相当，该触控单元200的面积过大可能会造成面板上出现触控盲点，过小则会造成误触信号。
示例性地，每个触控单元200的平均边长为L，L的大小范围为3.5mm～5mm，例如L为4mm；因为人的手指与触控显示面板100接触的直径约为4mm左右。每个触控单元200的平均边长与每个第一触控子电极213的平均对角线长度以及每个第二触控子电极211的平均对角线长度相同，也与相邻的第一触控子电极213的中心距离、相邻的第二触控子电极211的中心距离相同。
在一些实施例中，如图8A所示，多条触控线201中位于相邻的第一触控子电极213与第二触控子电极211的分界区D1的部分设置有分隔断口20101，多条触控线201中的至少一部分触控线201上设置的断口2010包括分隔断口20101。
其中，分隔断口20101将所在的触控线201分隔为两条触控子线20100，例如每个分隔断口20101位于所在的第一触控线的中部，两条触控子线20100中的一条属于第一触控子电极213，另一条属于第二触控子电极211，以使所述相邻的第一触控子电极213与第二触控子电极211相互绝缘。
可以理解的是，这里的触控子线20100可以为第一触控线、第二触控线或第三触控线的一部分，即分隔断口20101将所在的触控线201分隔为两条第一触控线、第二触控线或第三触控线。
本公开的至少一实施例提供的第一触控子电极213与第二触控子电极211相互绝缘通过断口2010实现，相较于通过设置虚拟(dummy)电极进行绝缘，可以提高触控电极的设置面积，提高触控电极的密度，从而提高触控的灵敏度。
在一些实施例中，位于相邻的第一触控子电极213与第二触控子电极211的分界区D1的多条触控线201上的断口2010数量大于非分界区的多条触控线201上的断口2010数量，多条触控线201包括多条第一触控线2011、多条第二触控线2012和多条第三触控线2013。其中，非分界区为多条触控线201所在的区域中除分界区D1之外的其他区域。
需要说明的是，相邻的第一触控子电极213与第二触控子电极211的分界区D1是指彼此绝缘交叉的部分，而处于非绝缘的部分属于非分界区。例如，在一个触控单元200中，如图8A和图8B所示，分界区D1是指位于一个触控单元200的对角线位置的区域，非分界区是指一个触控单元200中，除分界区D1之外的其他区域。
示例性地，继续参照图8A和图8B，在分界区D1，多条第一触控线、多条第二触控线和多条第三触控线定义的多个触控网格202中，每一触控网格202中设置的断口数量为2、3、或4，而在非分界区中，多条第一触控线、多条第二触控线和多条第三触控线定义的多个触控网格202中，每一触控网格202中设置的断口数量为0、1或2，因此，位于分界区D1多个触控网格202中设置的断口2010数量的总和大于非分界区多个触控网格202中设置的断口2010数量的总和。
在一些实施例中，多条触控线201定义的多个触控网格202中，每一触控网格202在触控显示面板上的正投影为六边形，位于相邻的第一触控子电极213与第二触控子电极211的分界区D1的多条触控线201定义的每一触控网格的断口数量为2、3或4，位于非分界区的多条触控线201定义的每一触控网格202的断口数量为0、1或2。
示例性地，如图8A所示，多条触控线201定义的多个触控网格202中，每一触控网格202在触控显示面板上的正投影为六边形，在分界区D1，多条第一触控线、多条第二触控线和多条第三触控线定义的多个触控网格202中，每一触控网格202中设置的断口数量为2、3或4，而在非分界区中，多条第一触控线、多条第二触控线和多条第三触控线定义的多个触控网格202中，每一触控网格202中设置的断口数量为0、1或2，因此，位于分界区D1多个触控网格202中设置的断口2010数量的总和大于非分界区多个触控网格202中设置的断口2010数量的总和。
在一些实施例中，多条触控线201定义的多个触控网格202中，每一触控网格202在触控显示面板上的正投影为四边形，位于相邻的第一触控子电极213与第二触控子电极211的分界区D1的多条触控线201定义的每一触控网格202的断口数量为2或3，位于非分界区的多条触控线201定义的每一触控网格202的断口数量为0、1或2。
示例性地，如图8B所示，多条触控线201定义的多个触控网格202中，每一触控网格202在触控显示面板上的正投影为四边形，在分界区D1，多条第一触控线、多条第二触控线和多条第三触控线定义的多个触控网格202中， 每一触控网格202中设置的断口数量为2或3，而在非分界区中，多条第一触控线、多条第二触控线和多条第三触控定义的多个触控网格202中，每一触控网格202中设置的断口数量为0、1或2，因此，位于分界区D1多个触控网格202中设置的断口2010数量的总和大于非分界区多个触控网格202中设置的断口2010数量的总和。
在一些实施例中，如图9A～图9C，触控结构层20包括多个触控子电极TR，多个触控子电极TR中的至少部分触控子电极TR为金属触控子电极，另一部分触控子电极TR为透明导电触控子电极；第一区101中透明导电触控子电极占多个触控子电极TR的比值，小于第二区1021中透明导电触控子电极占多个触控子电极TR的比值；第二区1021中透明导电触控子电极占多个触控子电极TR的比值，小于第三区1022中透明导电触控子电极占多个触控子电极TR的比值。
需要说明的是，在图9A～图9C中，有图案填充的触控子电极TR表示金属触控子电极，无图案填充的触控子电极TR表示透明导电触控子电极。
在一些实施例中，透明导电触控子电极的透过率较金属触控子电极的透过率较高，因此，一区域中，透明导电触控子电极占多个触控子电极TR的比值越大，则一区域的整体透过率越高，其中，透过率为，一区域中来自触控结构层20一侧的入射光线中，穿过多条触控线201的照射到阳极层上的入射量与整个入射总量的比值。
示例性地，第一区101的透过率小于第二区1021的透过率，第二区1021的透过率小于第三区1022的透过率，通过设置金属触控子电极和透明导电触控子电极的比例来改变各区域的透过率，进而增强反射率，使得第一区101、第二区1021和第三区1022的反射率一致，最终改善区域光学不良的问题。
如图10A和图10B所示，图10A表示光线穿过金属触控子电极的路径示意图，图10B表示光线穿过透明导电触控子电极的路径示意图，可见，透明导电触控子电极的透过率较高，从外界射入的大部分光线能够透过透明导电触控子电极入射到阳极层131上，从而能够提高光线的反射率。
在一些实施例中，在第三区1022、第二区1021和第一区101中，金属触控子电极和透明导电触控子电极的比值逐渐增大。
示例性地，如图9A所示，图9A为第三区1022的局部图，其中，金属触控子电极较透明导电触控子电极占比较小，所以，金属触控子电极与透明导电触控子电极的数量比值较小，且小于1，例如，金属触控子电极与透明导电触控子电极比值为1/3。
示例性地，如图9B所示，图9B为第二区1021的局部图，其中，金属触控子电极较透明导电触控子电极占比相当，所以，金属触控子电极与透明导电触控子电极的数量比值接近于1。
示例性地，如图9C所示，图9C为第一区101的局部图，其中，金属触控子电极较透明导电触控子电极占比较大，所以，金属触控子电极与透明导电触控子电极的数量比值较大，且大于1。
在一些实施例中，第一区101中的多个触控子电极TR均为金属触控子电极。
示例性地，通过以上设置，能够通过改变金属触控子电极和透明导电触控子电极的占比，来改变各区域的透过率，进而增强反射率，使得第一区101、第二区1021和第三区1022的反射率一致，最终改善区域光学不良的问题。
本公开的上述实施例中的触控显示装置1000的有益效果和上述一些实施例所述的触控显示面板100的有益效果相同，此处不再赘述。
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。
