Description

触控显示装置 技术领域
本申请涉及显示领域，尤其涉及一种触控显示装置。
 背景技术
有机发光二极管On-cell触控显示（OLED On-cell Touch）技术，又称DOT技术(Direct On-Cell Touch)集成有机发光二极管显示面板和触控结构，相较于外挂式触控面板（Touch Panel）技术具有更高的透过率、耐弯折性、及轻薄等优点，已成为柔性OLED显示未来趋势。此技术为在OLED面板的薄膜封装(Thin-Film Encapsulation, TFE)上直接利用低温工艺（温度小于或者等于90℃）制作触控结构，从而实现OLED和Touch结构的集成。已知的一种DOT触控显示面板的结构如图1所示，OLED面板10、TFE封装层20、绝缘层30以及触控模组40依次层叠设置。触控模组40包括设置于绝缘层30上的驱动电极41、感应电极42以及设置于封装层20上被绝缘层30覆盖的桥接电极43。驱动电极41和感应电极42设置于同层。绝缘层30中开设有过孔31。相邻两个驱动电极41或者相邻两个感应电极42通过过孔31连接至桥接电极43并导通。图1中以驱动电极41需要桥接为例，需要在绝缘层30上通过干刻工艺形成过孔31，驱动电极41与桥接电极43进行桥接。为保证导通效果，桥接位置的驱动电极41需要考虑对位公差，所以此位置的金属宽度大于其他位置。该技术带来以下缺陷：驱动电极41或者感应电极42桥接位置的桥接导通点宽度大于其他位置的金属宽度，导致此处像素发光与非桥接位置的光学特性有差异；随触控精度越高，触控电极越多，金属桥接点也越多，制程中干刻过孔位点越多，而且显示区和绑定（pad-bonding）区蚀刻深度不一样，为保证过孔深度均匀性从而使触控电极实现导通，对低温干刻工艺挑战很大，触控失效风险较高，特别是在高世代面板线制程中，低温干刻工艺风险对良率影响较大；低温制程下大量的桥接电极43及过孔31结构强度较弱，折叠屏中产生断路的风险较高。

下面将结合本申请实施方式中的附图，对本申请中的技术方案进行清楚、完整地描述。显然，所描述的实施方式仅仅是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，本领域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方式，都属于本申请保护的范围。
请参考图2，本申请第一实施方式提供一种触控显示装置1，其包括显示模组11和触控模组12。显示模组11和触控模组12层叠设置。其中，显示模组11可以为主动发光型显示模组，例如有机发光二极管（OLED）显示模组、微发光二极管（micro-LED）显示模组或者亚毫米发光二极管（mini-LED）显示模组等。在一个实施方式中，显示模组11也可以为被动发光型显示模组，例如液晶显示模组。显示模组11可以为柔性显示模组，也可以为非柔性显示模组。在本实施方式中，显示模组11为主动发光型的柔性显示模组。显示模组11包括有机发光二极管显示面板100。虽然未图示，但有机发光二极管显示面板100包括基板、设置于基板上的驱动电路层、安装于驱动电路层上的有机发光单元以及薄膜封装层等。显示模组11和触控模组12之间还设置有第一绝缘层200，也即有机发光二极管显示面板100和触控模组12之间还设置有第一绝缘层200。
触控模组12包括依次层叠设置的第一触控电极层300、第二绝缘层400和第二触控电极层500。在本实施方式中，第一触控电极层300位于显示模组11与第二触控电极层500之间。在本申请其他实施方式中，可以是第二触控电极层500位于显示模组11与第一触控电极层300之间。第一触控电极层300和第二触控电极层500的其中一个为触控驱动电极层，另一个为触控感应电极层。在本申请一个实施方式中，在第一触控电极层300和第二触控电极层500中，靠近显示模组11的为触控驱动电极层，远离显示模组11的为触控感应电极层。
此外，触控模组12远离显示模组11一侧还包括第三绝缘层600。第三绝缘层600为外涂（overcoating）层或者称为有机平坦保护层。
第一绝缘层200、第二绝缘层400和第三绝缘层600的材料包括有机绝缘材料或者无机绝缘材料。第一触控电极层300和第二触控电极层500的材料可以采用金、银、铜、锂、钠、钾、镁、铝、锌及其组合，也可采用导电金属材料氧化铟锡、掺铝氧化锌、掺锑氧化锡及其组合。
请参考图3，触控显示装置1具有触控显示区1A和位于触控显示区1A的一侧的绑定区1B。绑定区1B中设置有多个焊垫。焊垫与第二触控电极层500位于同层。
第一触控电极层300包括第一触控电极301和连接于第一触控电极301的第一引线302。第二触控电极层500包括第二触控电极501和连接于第二触控电极501的第二引线502。第一引线302和第二引线502均为金属走线。第一触控电极301和第二触控电极501中的一个为触控驱动电极，另一个为触控感应电极，二者共同构成矩阵式投射电容。第一触控电极301和第二触控电极501可以为菱形或长条形图案等。在本实施方式中，第一触控电极301为菱形，且沿第一方向D1排列。第二触控电极501也为菱形，且沿第二方向D2排列。第一方向D1与第二方向D2垂直。在一个实施方式中，第一方向D1为竖直方向，第二方向D2为水平方向。焊垫包括用于连接第一触控电极301的第一焊垫503和用于连接第二触控电极501的第二焊垫504、505。第二焊垫504和第二焊垫505设置于第一焊垫503两侧，第二焊垫504用于连接上半部分的第二触控电极501和第二焊垫505用于连接下半部分的第二触控电极501。第一引线302从第一触控电极301延伸至绑定区1B，经过开设于第二绝缘层400中的过孔401延伸至第二触控电极层500与第一焊垫503电连接，从而电连接至触控控制电路（未图示）。第二引线502从第二触控电极501延伸至绑定区1B与第二焊垫504、505电连接，从而电连接至触控控制电路（未图示）。
在本申请其他实施方式中，第二触控电极层500位于显示模组11与第一触控电极层300之间。同样地，第一引线302从第一触控电极301延伸至绑定区1B，经过开设于第二绝缘层400中的过孔401延伸至第二触控电极层500与第一焊垫503电连接，从而电连接至触控控制电路（未图示）。
本实施方式所提供的触控显示装置通过将on-cell touch中的触控驱动电极与触控感应电极设置在不同层，可以避免单层桥接过孔式设计中的金属桥接点导致的光学效果不一致。由于避开了单层桥接过孔式设计，大大降低了低温干刻工艺风险，提升了柔性DOT面板的弯折可靠性。
请参考图4至图6，在本申请的另一实施方式中，为不影响显示模组11的发光，第一触控电极301和第二触控电极501采用金属网格（metal mesh）结构。
第一触控电极层300包括相交的多条第一触控金属线3011和多条第二触控金属线3012。相交的多条第一触控金属线3011和多条第二触控金属线3012形成呈阵列排布的多个第一触控图案301P。请参考图7（a），第一触控图案301P的形状为菱形。多条第一触控金属线3011沿第三方向D3延伸且在第四方向D4上间隔排列。多条第二触控金属线3012沿第四方向D4延伸且在第三方向D3上间隔排列。
第一触控电极层300包括多个第一触控电极301和设置在相邻两个第一触控电极301之间的第一虚拟电极301D。第一虚拟电极301D与第一触控电极301通过设置于第一触控金属线3011和第二触控金属线3012中的第一断口3013相互绝缘。多个第一断口3013可以按照一定规律排布使第一触控电极301形成各种图案，如长条状或者菱形、树枝图案等。本实施例中，多个第一断口3013（或者叫间隙）沿第一方向D1排列，即多个第一断口3013呈纵向排列。两条纵向排列的第一断口3013将多个原本相连的多个第一触控图案301P分成两个长条状的第一触控电极301和位于该第两个长条状的第一触控电极301之间的第一虚拟电极301D。第一虚拟电极301D为悬浮图案，与其他电极保持绝缘，可以通过调整第一虚拟电极301D的宽度及面积调节第一触控电极301的对地电容。
第二触控电极层500包括相交的多条第三触控金属线5011和多条第四触控金属线5012。相交的多条第三触控金属线5011和多条第四触控金属线5012形成呈阵列排布的多个第二触控图案501P。请参考图7（b），第二触控图案501P的形状为菱形。多条第三触控金属线5011沿第三方向D3延伸且在第四方向D4上间隔排列。多条第四触控金属线5012沿第四方向D4延伸并在第三方向D3上间隔排列。在一个实施方式中，第一触控图案301P和第二触控图案501P的大小，即边长相同。
第二触控电极层500包括多个第二触控电极501和设置在相邻两个第二触控电极501之间的第二虚拟电极501D。第二虚拟电极501D与第二触控电极501通过设置于第三触控金属线5011和第四触控金属线5012中的第二断口5013相互绝缘。多个第二断口5013可以按照一定规律排布使第二触控电极501形成各种图案，如长条状或者菱形、树枝图案等。本实施例中，多个第二断口5013（或者叫间隙）沿第二方向D2排列，第一方向D1与第二方向D2垂直，即多个第二断口5013呈横向排列。两条横向排列的第二断口5013将多个原本相连的多个第二触控图案501P分成两个长条状的第二触控电极501和位于该第两个长条状的第二触控电极501之间的第二虚拟电极501D。第二虚拟电极501D为悬浮图案，与其他电极保持绝缘，可以通过调整第二虚拟电极501D的宽度及面积调节第二触控电极501的对地电容。
本实施例中，第一触控电极层300中的第一触控电极301呈纵向排列，第二触控电极层500中的第二触控电极501呈横向排列，两者在不同层形成互容触控感应图案。如图6所示，图6为本实施方式的第一触控电极层300、第二触控电极层500和像素矩阵的俯视示意图。为了便于说明，使用较粗的线条表示第一触控电极层300。在俯视时，第一触控金属线3011和第三触控金属线5011按照一条第一触控金属线3011、一条第三触控金属线5011的顺序交替间隔设置，第二触控金属线3012和第四触控金属线5012按照一条第二触控金属线3012、一条第四触控金属线5012的顺序交替间隔设置。相邻两条触控金属线之间的垂直距离可以相等。请参考图7（c），第一触控电极层300和第二触控电极层500以如下方式排列：在俯视时，每一第一触控图案301P的中心O与一个第二触控图案501P的一个端点P重叠，且该第二触控图案501P的中心O也与该第一触控图案301P的一个端点P重叠。此处，虽然只说明了一个第一触控图案301P与一个第二触控图案501P的相对位置关系，由于第一触控电极层300和第二触控电极层500中的第一触控图案301P和第二触控图案501P是呈阵列排布，因此，第一触控电极层300和第二触控电极层500的相对位置关系可以通过这样确定下来。另外，这里只说明了一个第一触控图案301P与和该第一触控图案301P在水平方向上重叠的一个第二触控图案501P的相对位置关系，在本实施方式中，一个第一触控图案301P与和该第一触控图案301P在垂直方向上重叠的一个第二触控图案501P的相对位置关系也可以用在俯视时，每一第一触控图案301P的中心O与一个第二触控图案501P的一个端点P重叠，且该第二触控图案501P的中心O也与该第一触控图案301P的一个端点P重叠来说明。本实施方式中，列举了第一触控图案301P和第二触控图案501P的边长相同的例子，在本申请其他实施方式中，第一触控图案301P和第二触控图案501P的边长也可以不相同，只要在俯视时，每一第一触控金属线3011与每一条第三触控金属线5011错开，每一第二触控金属线3013与每一条第四触控金属线5012错开即可。在本实施方式中，通过采用按照一定规律排列的金属网格电极结构，能够避免上下层金属网格的重叠产生莫尔条纹而影响光学效果。
在本申请中，不限定显示模组11中像素单元的排列方式。本申请的显示模组11中像素单元的排列方式可以是现有技术中任意一种像素单元排列方式，例如RBG并置排列方式。在一种实施方式中，显示模组11中像素单元的排列方式为P（pentile）排列。显示模组11包括P排列的多个子像素SP。多个子像素SP构成像素矩阵。在一个实施方式中，如图5和图6所示，pentile排列的像素结构可按如下方式配置：多个具有绿色子像素G和红色子像素R的第一像素P1沿第三方向D3间隔排列，多个具有绿色子像素G和蓝色子像素B的第二像素P2沿第三方向D3间隔排列，第一像素P1排成的列与第二像素P2排成的列沿第四方向D4交替间隔排列。第三方向D3、第四方向D4可以与第一方向D1、第二方向D2相同，也可以不同。在本实施方式中，第三方向D3、第四方向D4与第一方向D1、第二方向D2各不相同。第三方向D3与第四方向D4相互垂直。第三方向D3例如为与第二方向D2形成30至60度夹角。在俯视时，第一触控图案301P包围4个子像素，其中包括两个绿色子像素G、1个红色子像素R以及1个蓝色子像素B。第二触控图案501P也包围4个子像素，其中包括两个绿色子像素G、1个红色子像素R以及1个蓝色子像素B。在俯视时，每个子像素四周均被触控金属线包围。即，每个子像素位于触控金属线在子像素所构成的平面上的正投影的范围内。这里的触控金属线是第一触控金属线3011、第二触控金属线3012、第三触控金属线5011和第四触控金属线5012的统称。其中，在俯视时，每个子像素四周分别被一条第一触控金属线3011、一条第二触控金属线3012、一条第三触控金属线5011和一条第四触控金属线5012包围。即，每个子像素位于一条第一触控金属线3011、一条第二触控金属线3012、一条第三触控金属线5011和一条第四触控金属线5012在子像素所构成的平面上的正投影的范围内。由此，触控显示装置1的触控显示区域1A的各处发光亮度保持一致。
请参考图8至图10，本申请另一实施方式的触控显示装置1与第一实施方式的触控显示装置1结构大致相同，区别点仅在于第一触控电极层300和第二触控电极层500的触控图案的结构。在本实施方式中，请参考图11（a），第一触控图案301P'包括由两条第一触控金属线3011和两条第二触控金属线3012相交构成的一个大的菱形，在大的菱形的一个夹角α的两条边的四分之一边长处分别具有一条第一触控金属线3011和一条第二触控金属线3012。由此，将该大的菱形分割为两个相互连接的小菱形和位于两个小菱形两侧的两个平行四边形。请参考图11（b），第二触控图案501P'也包括由两条第一触控金属线3011和两条第二触控金属线3012相交构成的一个大的菱形，在大的菱形的一个夹角α的两条边的四分之一边长处分别具有一条第三触控金属线5011和一条第四触控金属线5012。由此，将该大的菱形分割为两个相互连接的小菱形和位于两个小菱形两侧的两个平行四边形。在本实施方式中，第一触控图案301P'与第二触控图案501P'的形状和大小均相同。
定义第一触控图案301P'的夹角α的顶点为第一端点P1，与该夹角α相对的顶点为第二端点P2，第二触控图案501P'的夹角α的顶点为第一端点P1，与该夹角α相对的顶点为第二端点P2。在俯视时，每一第一触控图案301P’的第一端点P1与一个第二触控图案501P'的中心O重叠，且该第一触控图案301P'的中心O也与该第二触控图案501P'的第二端点P2重叠。其结果，在俯视时，第一触控金属线3011和第三触控金属线5011按照两条第一触控金属线3011、两条第三触控金属线5011的顺序交替间隔设置，第二触控金属线3012和第四触控金属线5012按照两条第二触控金属线3012、两条第四触控金属线5012的顺序交替间隔设置。
在本实施方式中，通过采用按照一定规律排列的金属网格电极结构，能够避免上下层金属网格的重叠产生莫尔条纹而影响光学效果。
请参考图11（a）至图11（c），在俯视时，第一触控图案301P'包围16个子像素，其中包括8个绿色子像素G、4个红色子像素R以及4个蓝色子像素B。第二触控图案501P'也包围16个子像素，其中包括8个绿色子像素G、4个红色子像素R以及4个蓝色子像素B。第一触控图案301P’和第二触控图案501P'所包围的16子像素排列相同。在俯视时，每个子像素四周均被触控金属线包围。即，每个子像素位于触控金属线在子像素所构成的平面上的正投影的范围内。这里的触控金属线是第一触控金属线3011、第二触控金属线3012、第三触控金属线5011和第四触控金属线5012的统称。由此，触控显示装置1的触控显示区域1A的各处发光亮度保持一致。
在本实施方式中，第一虚拟电极301D和第二虚拟电极501D以及第一断口3013和第二断口2013等特征与上述实施方式相同，在此省略说明。
请参考图12至图14，本申请另一实施方式的触控显示装置1与第一实施方式的触控显示装置1结构大致相同，区别点仅在于第一触控电极层300和第二触控电极层500的触控图案的结构。在本实施方式中，请参考图15（a），第一触控图案301''包括由两条第一触控金属线3011和两条第二触控金属线3012相交构成的一个大的菱形，在大的菱形的一个夹角α的两条边的六分之一边长处和二分之一边长处分别具有两条第一触控金属线3011和两条第二触控金属线3012。由此，将该大的菱形分割为三个相互连接的小菱形和位于三个小菱形两侧的四个平行四边形。请参考图15（b），第二触控图案301''包括由两条第三触控金属线5011和两条第四触控金属线5012相交构成的一个大的菱形，在大的菱形的一个夹角α的两条边的六分之一边长处和二分之一边长处分别具有第三触控金属线5011和两条第四触控金属线5012。由此，将该大的菱形分割为三个相互连接的小菱形和位于三个小菱形两侧的四个平行四边形。在本实施方式中，第一触控图案301P''与第二触控图案501P''大小，即该大的菱形的边长相同。
定义第一触控图案301P''的夹角α的顶点称为第一顶点P1，与夹角α相对的夹角的顶点为第二顶点P2，第二触控图案501P''的夹角α的顶点称为第一顶点P1，与夹角α相对的夹角的顶点为第二顶点P2。在本实施方式中，第一顶点P1和第二顶点P2的连接线与第二方向D2平行。第一触控电极层300和第二触控电极层500以在俯视时，每一第二触控图案501P''的第二顶点P2位于一个第一触控图案301P''的对角线上距离第一顶点P1对角线的六分之一长度的位置，且该第一触控图案301P''的第二顶点P2位于该第二触控图案501P''对角线上距离第一顶点P1对角线的六分之一长度的位置的方式配置。其结果，在俯视时，第一触控金属线3011和第三触控金属线5011按照两条第三触控金属线5011、两条第一触控金属线3011、一条第三触控金属线5011、一条第一触控金属线3011的顺序（在图中，从左至右）交替间隔设置，第二触控金属线3012和第四触控金属线5012按照两条第二触控金属线3012、两条第四触控金属线5012、一条第二触控金属线3012、一条第四触控金属线5012（在图中，从左至右）的顺序交替间隔设置。
在本实施方式中，通过采用按照一定规律排列的金属网格电极结构，能够避免上下层金属网格的重叠产生莫尔条纹而影响光学效果。
请参考图15（a）至图15（c），在俯视时，第一触控图案301P''包围36个子像素，其中包括18个绿色子像素G、9个红色子像素R以及9个蓝色子像素B。第二触控图案501P''也包围36个子像素，其中包括18个绿色子像素G、9个红色子像素R以及9个蓝色子像素B。第一触控图案301P''和第二触控图案501P''所包围的36子像素排列相同。在俯视时，每个子像素四周均被触控金属线包围。即，每个子像素位于触控金属线在子像素所构成的平面上的正投影的范围内。这里的触控金属线是第一触控金属线3011、第二触控金属线3012、第三触控金属线5011和第四触控金属线5012的统称。由此，触控显示装置1的触控显示区域1A的各处发光亮度保持一致。
在本实施方式中，第一虚拟电极301D和第二虚拟电极501D以及第一断口和第二断口等特征与上述实施方式相同，在此省略说明。
相较于现有技术，本申请所提供的触控显示装置通过将on-cell touch中的触控驱动电极与触控感应电极设置在不同层，可以避免单层桥接过孔式设计中的金属桥接点导致的光学效果不一致。由于避开了单层桥接过孔式设计，大大降低了低温干刻工艺风险，提升了柔性DOT面板的弯折可靠性。此外，通过采用按照一定规律排列的金属网格电极结构，能够避免上下层金属网格的重叠产生莫尔条纹而影响光学效果。
