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，都属于本申请保护的范围。此外，应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。在本申请中，在未作相反说明的情况下，使用的方位词如“上”和“下”通常是指装置实际使用或工作状态下的上和下，具体为附图中的图面方向；而“内”和“外”则是针对装置的轮廓而言的。
请参阅图1，图1是本申请实施例提供的第一种触控显示面板的俯视结构示意图。本申请实施例提供一种触控显示面板，所述触控显示面板包括显示区，所述显示区包括平面显示区100a、至少两个第一曲面显示区100b和至少一个第二曲面显示区100c，所述第一曲面显示区100b分别连接于所述平面显示区100a的相邻的两条侧边，所述第二曲面显示区100c位于两个所述第一曲面显示区100b之间且对应于所述平面显示区100a的相邻的两条所述侧边的交汇处。
在俯视视角下，所述平面显示区100a的形状可以呈矩形，在本申请实施例中，所述触控显示面板可包括四个所述第一曲面显示区100b和四个所述第二曲面显示区100c，四个所述第一曲面显示区100b分别与所述平面显示区100a的四条侧边相接。所述平面显示区100a、所述第一曲面显示区100b和所述第二曲面显示区100c均可实现显示功能。
可选地，所述触控显示面板还包括感应区。进一步地，所述感应区可位于所述平面显示区100a内，所述感应区用于使所述显示面板实现感测功能。所述触控显示面板包括对应所述感应区设置的传感器。可选地，所述传感器包括摄像头、光传感器、距离传感器、指纹识别传感器等。
请继续参阅图1，以在俯视图视角下，所述触控显示面板的所述平面显示区100a呈矩形，所述触控显示面板包括四个所述第一曲面显示区100b及四个所述第二曲面显示区100c为例，对所述触控显示面板进行说明。
当然地，在俯视图视角下，相邻两条所述侧边相交处还可以为倒角的四边形。
所述显示区还包括非触控区100d，所述非触控区100d至少位于部分所述第二曲面显示区100c，所述非触控区100d是指所述显示区中仅具有显示功能但不具有触控功能的区域，所述显示区中除了所述非触控区100d之外的区域则同时具有显示功能和触控功能。
由于所述非触控区100d取消触控，则所述非触控区100d的膜层厚度小于其他显示区域的膜层厚度，进一步地，所述第二曲面显示区100c的至少部分区域的膜层厚度小于其他显示区域的膜层厚度。又因所述第二曲面显示区100c的面积较小且其所在位置导致用户在此区域进行触控操作较为不便，故实际上，在所述第二曲面显示区100c内设置用于实现触控功能的触控器件无实际应用意义。基于此，本申请通过在所述第二曲面显示区100c的至少部分区域取消触控，使得所述第二曲面显示区100c的至少部分区域的整体膜层厚度降低，所述第二曲面显示区100c更易于弯折，从而能够改善所述第二曲面显示区100c的应力集中，避免所述第二曲面显示区100c中的发光器件在高温高湿等严苛条件下出现封装失效的不良，有利于增强显示可靠性。
在一种实施方式中，所述非触控区100d包括整个所述第二曲面显示区100c，即，整个所述第二曲面显示区100c均取消触控，在改善所述第二曲面显示区100c的应力集中的同时，能够避免用户在使用时在此区域出现误触控的情况，提高了用户体验。
在一种实施方式中，请参阅图2，图2是本申请实施例提供的第二种触控显示面板的俯视结构示意图。所述非触控区100d仅包括部分所述第二曲面显示区100c，也即所述第二曲面显示区100c仅有部分区域取消触控，而其余部分区域依然具有触控功能。具体地，所述第二曲面显示区100c包括第一子区1001c和第二子区1002c，所述第二子区1002c位于所述平面显示区100a和所述第一子区1001c之间，即，所述第一子区1001c位于所述第二曲面显示区100c边缘，所述第一子区1001c的压缩率大于所述第二子区1002c的压缩率。其中，所述非触控区100d至少包括所述第一子区1001c。
需要说明的是，所述第二曲面显示区100c在不同区域具有不同的压缩率，所述第二曲面显示区100c在进行3D贴合工艺处理时，所述第二曲面显示区100c进行收缩以实现所述第一曲面显示区100b与模组的紧密贴合。
所述第一子区1001c的压缩率大于所述第二子区1002c的压缩率，所述第一子区1001c的应力集中相较于所述第二子区1002c的应力集中较为严重，因此，仅需将所述第一子区1001c取消触控，而所述第二子区1002c不取消触控，在尽量不牺牲触控占比的情况下，起到改善所述第二曲面显示区100c的应力集中的目的。
具体地，所述第一子区1001c的压缩率大于或等于0.1。
请参阅图3，图3是本申请实施例提供的一种互容式触控显示面板的截面结构示意图。从膜层结构上而言，所述触控显示面板包括基板11、显示功能层12和触控功能层13，所述显示功能层12设置于所述基板11上并位于所述平面显示区100a、所述第一曲面显示区100b和所述第二曲面显示区100c。所述触控功能层13设置于所述显示功能层12上，所述触控功能层13位于所述平面显示区100a、至少部分所述第一曲面显示区100b和所述第二子区1002c。
可选地，所述基板11包括柔性基板，以便于所述第一曲面显示区100b和所述第二曲面显示区100c弯折。所述柔性基板可以包括两个柔性衬底和设置于两个柔性衬底之间的阻隔层。两个柔性衬底的材料分别独立地选自聚酰亚胺（PI）、聚萘二甲酸乙二醇酯（PEN）、聚对苯二甲酸乙二醇酯（PET）、聚芳酯（PAR）、聚碳酸酯（PC）、聚醚酰亚胺（PEI）和聚醚砜（PES）中的一种。阻隔层的材料可以选自氧化硅（SiOx）、氮化硅（SiNx）、氮氧化硅（SiON）等无机材料及其叠层，用于防止水汽从柔性衬底扩散至驱动电路层。
所述显示功能层12用于实现显示功能，所述触控功能层13用于实现触控功能。具体地，所述显示功能层12包括驱动电路层121、发光器件层122和封装层123，所述驱动电路层121设置于所述基板11上，所述发光器件层122设置于所述驱动电路层121上，所述封装层123覆盖所述发光器件层122，所述触控功能层13设置于所述封装层123上。
具体地，所述驱动电路层121可以包括用于驱动发光器件发光的多个像素驱动电路，每一所述像素驱动电路包括多个薄膜晶体管，多个所述薄膜晶体管包括驱动晶体管，所述驱动晶体管可以包括有源层、栅极绝缘层、栅极、层间介质层和源漏极金属层等膜层。所述发光器件层122可以包括阳极、像素定义层、发光功能层和阴极，所述发光功能层包括电子传输层、电子注入层、发光层、空穴注入层和空穴传输层等膜层。
所述封装层123用于对所述发光器件层122中的所述发光层进行封装，以阻隔外界水汽和氧气对所述发光层中的有机发光材料造成侵蚀，造成有机发光材料失效，降低所述触控显示面板的使用寿命。具体地，所述封装层123可以采用薄膜封装，所述封装层123可以包括依次设置于所述发光器件层122的第一无机封装层、有机封装层和第二无机封装层，以上均为现有技术，故在此不再进行详述。
具体地，所述触控功能层13包括无机绝缘层、触控金属层134和有机平坦层135，所述无机绝缘层位于所述封装层123上，所述触控金属层134位于所述无机绝缘层上，所述有机平坦层135覆盖所述触控金属层134。在图3中，所述无机绝缘层在所述基板11上的正投影位于所述封装层123在所述基板11上的正投影内，即，所述无机绝缘层在所述非触控区100d内未设置，具体地，所述无机绝缘层在所述第二曲面显示区100c内未设置。
可选地，所述无机绝缘层的材料可以包括氮化硅、氧化硅和氮氧化硅中的其中一种或多种的组合，所述有机平坦层135可以包括聚酰亚胺。
进一步地，请参阅图4，图4是本申请实施例提供的另一种互容式触控显示面板的截面结构示意图。图4与图3的不同之处在于，所述无机绝缘层在所述基板11上的正投影覆盖所述封装层123在所述基板11上的正投影，即，所述无机绝缘层位于整个所述显示区，也即是说，所述无机绝缘层也位于所述非触控区100d，而所述触控金属层134未设置于所述非触控区100d。因此，在改善应力集中的同时，由于所述无机绝缘层具有协助提升水氧阻隔的能力，故可同所述封装层123一起进行封装，能够进一步防止由于水氧入侵，从而能够所述触控显示面板的使用寿命。
需要说明的是，所述触控功能层13的电容方式可以为自容感应和互容感应，对于不同的电容方式，触控电极以及触控走线的排布和连接方式均存在不同。因此，根据不同的电容方式，本申请对触控引线的排布进行了适应性设计，以下将进行具体说明。此外，为了清楚地阐述技术方案，本申请以所述非触控区100d包括整个所述第二曲面显示区100c为例。
在一种实施例中，请继续参阅图3和图4，所述触控功能层13为互容式触控功能层13。具体地，所述触控功能层13包括在所述触控显示面板厚度方向上依次设置的第一无机绝缘层131、桥接金属层132、第二无机绝缘层133、触控金属层134和有机平坦层135。所述第一无机绝缘层131设置于所述封装层123上，所述桥接金属层132设置于所述第一无机绝缘层131上，所述第二无机绝缘层133覆盖所述桥接金属层132，所述触控金属层134设置于所述第二无机绝缘层133上，所述有机平坦层135覆盖所述触控金属层134。
请参阅图5，图5是本申请实施例提供的一种互容式触控显示面板的走线排布示意图。所述触控金属层134包括多个互容式触控电极1341和多条互容式触控走线1342，多个所述互容式触控电极1341包括感应电极1341a和驱动电极1341b，相邻两个所述感应电极1341a通过贯穿所述第二无机绝缘层133的过孔与所述桥接金属层132电连接。
由于位于所述触控显示面板上边框位置处的两个所述第二曲面显示区100c中无金属走线，所述互容式触控走线1342可以较为容易地避开所述第二曲面显示区100c。然而，所述触控显示面板的下边框位置处的走线较多，现有技术中的所述互容式触控走线1342采用直角下拉设计，所述互容式触控走线1342容易经过所述第二曲面显示区100c。
有鉴于此，本申请通过与所述感应电极1341a连接的所述互容式触控走线1342在所述基板11上的正投影与所述第二曲面显示区100c不重叠，即所述互容式触控走线1342避开所述第二曲面显示区100c设计，以保证所述第二曲面显示区100c未设置有任何触控走线。需要注意的是，所述互容式触控走线1342应绕开所述发光器件层122中的发光区，以避免所述互容式触控走线1342影响所述发光区的正常出光。
可选地，所述互容式触控走线1342在靠近所述第二曲面显示区100c的绕线形状可与所述第二曲面显示区100c的形状相同。
在一种实施例中，请参阅图6，图6是本申请实施例提供的一种自容式触控显示面板的截面结构示意图。所述触控功能层13为自容式触控功能层13。具体地，所述自容式触控功能层13包括在所述触控显示面板厚度方向上依次设置的第一无机绝缘层131、触控金属层134和有机平坦层135。所述第一无机绝缘层131设置于所述封装层123上，所述触控金属层134设置于所述第一无机绝缘层131上，所述有机平坦层135覆盖所述触控金属层134。
请参阅图7，图7是本申请实施例提供的一种自容式触控显示面板的走线排布示意图。所述触控金属层134包括多个自容式触控电极1343和多条自容式触控走线1344，每个所述自容式触控电极1343分别连接一条自容式触控走线1344，所述自容式触控走线1344位于相邻两个所述自容式触控电极1343之间的间隔内，所述自容式触控走线1344的一端延伸至所述触控显示面板的边框区以与多个焊盘14对应连接。
进一步地，所述自容式触控走线1344位于与其对应连接的所述自容式触控电极1343远离所述触控显示面板的边缘的一侧，简单地说，可以将屏体分为左侧部分和右侧部分，位于屏体左侧的所述自容式触控走线1344从与其对应连接的所述自容式触控电极1343的右侧出线，而位于屏体右侧的所述自容式触控走线1344则从与其对应连接的所述自容式触控电极1343的左侧出线，这样设置的原因在于，可避免位于屏体边缘的所述自容式触控电极1343向下延伸至所述第二曲面显示区100c内。
需要说明的是，本申请实施例中的多条所述自容式触控走线1344可以采用对称设计，也可采用非对称设计，本申请对此不做限定。
可选地，请再次参阅图6，所述自容式触控电极1343和所述自容式触控走线1344同层设置。
进一步地,请参阅图8，图8是本申请实施例提供的另一种自容式触控显示面板的截面结构示意图。图8与图6的不同之处在于，为了减少相邻两个所述自容式触控电极1343之间的间距，所述自容式触控电极1343可与所述自容式触控走线1344异层设置。具体地，所述触控功能层13还包括第二无机绝缘层133，所述自容式触控走线1344位于所述第一无机绝缘层131上，所述第二无机绝缘层133覆盖所述自容式触控走线1344，所述自容式触控电极1343位于所述第二无机绝缘层133上且通过贯穿所述第二无机绝缘层133的过孔与对应的所述自容式触控走线1344连接。
进一步地，请继续参阅图2，所述第一曲面显示区100b包括第三子区1001b和第四子区1002b，所述第四子区1002b位于所述平面显示区100a和所述第三子区1001b之间，即，所述第三子区1001b位于所述第一曲面显示区100b边缘，所述第三子区1001b的弧度大于所述第四子区1002b的弧度；其中，所述非触控区100d至少位于所述第一子区1001c和所述第三子区1001b，所述触控功能层13位于所述平面显示区100a、所述第二子区1002c和所述第四子区1002b。
可以理解的是，所述第三子区1001b的弧度较高，导致此区域的应力集中较为严重，本申请通过在所述第三子区1001b取消触控，在改善所述第三子区1001b的应力集中的同时，可以防止人手误触带来的无效应用操作。具体地，所述第三子区1001b的弧度大于60度。
当然地，也可将所述第一曲面显示区100b的整个区域均取消触控，使得所述第一曲面显示区100b仅具有显示功能，而不具有触控功能。
可选地，所述触控显示面板可以为柔性显示面板，所述触控显示面板可以为有机发光二极管显示面板，量子点有机发光二极管显示面板、微发光二极管显示面板以及次毫米发光二极管显示面板等。根据驱动类型，所述触控显示面板可以为主动矩阵有机发光二极管显示面板或者被动矩阵有机发光二极管显示面板。
进一步地，所述触控显示面板还包括偏光片和盖板，所述偏光片设置于所述触控功能层13上，所述盖板设置于所述偏光片上，所述盖板和所述偏光片通过设置于两者之间的光学胶层粘接。
本申请还提供一种触控显示装置，所述触控显示装置包括上述实施例中的所述触控显示面板，所述触控显示装置可以包括固定终端(如电视、台式电脑等)，移动终端(如手机、笔记本电脑等)，以及可穿戴设备(如手环、虚拟显示设备、增强显示设备等)等。
有益效果为：本申请实施例提供的触控显示面板及触控显示装置，通过将显示区中的非触控区包括至少部分第二曲面显示区，第二曲面显示区的至少部分区域取消触控，能够降低第二曲面显示区的整体膜层厚度，从而改善第二曲面显示区的应力集中，避免显示发光器件在高温高湿等严苛条件下出现封装失效的不良，有利于增强显示可靠性。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
