具体实施方式
为了进一步说明本公开实施例提供的阵列基板、触控显示装置,下面结合说明书附图进行详细描述。
内嵌式触控面板相对于外嵌式触控面板等触控面板在成本、稳定性等方面有较大优势。内嵌式触控面板是将触控电极设置于面板内部的一种设计,对于像素设计要求较高。一般应用于TPC和MNT领域的中小尺寸面板,触 控感测(Touch sensor)块面积在4mm~6mm之间。以10英寸TPC产品为例,整个面板的触控感测块数量为1500块左右。以23.8英寸MNT产品为例,整个面板的触控感测块数量为3600块左右。而对于TV和IWB产品来说,触控感测块数量在1万~几万块。
如图1所示,面板中的触控感测块数量越多,需要对应设置的触控信号线的数量越多,而面板内的布局空间有限,在设置较多数量的触控信号线时,触控信号线的布局难度,以及触控信号线与触控芯片200之间的连接难度均会大大增加。

根据上述阵列基板的具体结构可知,本公开实施例提供的阵列基板中,沿第一方向相对设置了第一控制单元21和第二控制单元22,将所述多个触控感测块30划分为所述第一组电极块31和所述第二组电极块32,同时设置 了所述第一组触控信号线41和所述第二组触控信号线42,使得所述第一组触控信号线41分别与第一组电极块31和第一控制单元21耦接,由第一控制单元21通过第一组触控信号线41控制向第一组电极块31写入信号或接收第一组电极块31反馈的信号;使得所述第二组触控信号线42分别与第二组电极块32和第二控制单元22耦接,由第二控制单元22通过第二组触控信号线42控制向第二组电极块32写入信号或接收第二组电极块32反馈的信号。
因此,本公开实施例提供的阵列基板中,将整个阵列基板划分为沿第一方向排布,且能够分别控制触控的两部分,这样在布局所述触控信号线40时,能够提高起有效连接作用的触控信号线的数量,每条触控信号线40不必沿第一方向穿过整块阵列基板,只需穿过其对应的一组电极块所在区域即可,这样不仅降低了阵列基板中触控信号线40所需的布局空间,有效降低了大尺寸阵列基板中触控信号线40的布局难度,而且还改善了布局所述触控信号线40时,对阵列基板中各子像素的开口率的影响。
另外,上述设置方式使得整个阵列基板中的触控信号线40划分为两组,每组触控信号线40连接对应的控制单元,实现了阵列基板的双边驱动,从而很好的降低了触控信号线40与控制单元之间的连接难度。
如图12所示,在一些实施例中,每个触控感测块30包括彼此电连接且彼此间隔开的多个触控电极300;
如图4所示,所述阵列基板还包括:
多条栅线50,所述栅线50的至少部分沿所述第二方向延伸;
多条数据线51,所述数据线51的至少部分沿所述第一方向延伸,所述多条数据线51与所述多条栅线50交叉设置,限定出多个子像素区;
多个像素电极52,所述多个像素电极52与所述多个子像素区一一对应,所述像素电极52位于对应的子像素区中。
示例性的,每个触控感测块30包括的多个触控电极300呈阵列分布,相邻的触控电极300之间间隔设置,每个触控感测块30包括的多个触控电极300彼此电连接。
示例性的,所述触控电极300复用为阵列基板中的公共电极。在将所述 阵列基板应用于显示装置中时,当显示装置正常显示时,触控电极300作为公共电极;当显示装置实现触控功能时,控制单元控制触控扫描,触控电极300作为触控感应传感器。
值得注意,所述阵列基板中的触控感测块不是覆盖阵列基板部分连续区域的一整块电极层,而是由多块独立的公共电极构成,示例性的,所述公共电极与所述阵列基板中的子像素一一对应。
示例性的,所述多条栅线50沿所述第一方向排列,每条栅线50的至少部分沿所述第二方向延伸。
示例性的,所述多条数据线51沿所述第二方向排列,每条数据线51的至少部分沿所述第一方向延伸。
示例性的,所述多条数据线51与所述多条栅线50交叉设置,限定出呈阵列分布的多个子像素区。

示例性的,所述阵列基板还包括多个开关元件53,所述多个开关元件53与所述多个像素电极52一一对应,例如所述开关元件53为薄膜晶体管(TFT,thin film transistor),所述开关元件53包括第一极、第二极以及控制极,控制极为栅线的一部分,所述开关元件53的第二极与对应的像素电极52耦接。
示例性的,所述多个开关元件53呈阵列分布,能够划分为沿所述第一方向排列的多行开关元件53,也能够划分为沿所述第二方向排列的多列开关元件53。所述多条栅线50与所述多行开关元件53一一对应,每条栅线50与其对应的一行开关元件53的控制端分别耦接,用于控制其耦接的一行开关元件53的导通与截止。
所述多条数据线51与多列开关元件53的耦接方式多种多样,示例性的,所述多条数据线51与多列开关元件53一一对应,每条数据线51与其对应的一列开关元件53中各开关元件53的第一极分别耦接,用于向所述各开关元 件53的第一极写入数据信号。示例性的,所述数据线51采用与其两侧相邻的两列开关元件53中耦接,与该数据线51连接的开关元件53交替位于该数据线51的两侧,该结构可以实现在驱动时,沿第一方向排布的一行数据线51交替给正负极性的信号,且使得一列像素电极52交替获得正负极性的信号。
值得注意,上述阵列基板中,由于触控感测块30数量较多,且每个触控感测块30都需要连接一根触控信号线40,因此,通过设置双边绑定焊盘(Bonding PAD),即通过双边驱动来克服触控信号线40布局和与触控芯片200连接的难题。
如图4和图5所示,在采用上述结构的阵列基板时,以每边PAD上的触控芯片200驱动半边屏的触控感测块30为例,为了保证阵列基板中各区域的负载一致,第一组触控信号线41和第二组触控信号线42均会延伸至阵列基板的中间区域,使沿第一方向相正对的两条触控信号线40之间距离较近,一般保证不会发生short即可,示例性的,距离L0设置为大于或等于4μm,同时触控信号线40一般比较细,常见的宽度在4μm~10μm之间。
发明人在实验过程中发现,上述实施例提供的阵列基板中,分别驱动半边屏的触控信号线40会沿第一方向正对着,在所述中间区域形成正对着的尖端,使所述中间区域容易发生静电释放现象(ESD),造成触控信号线40烧毁,引起两根相对的触控信号线40短路。
如图6~图8所示,在一些实施例中,设置沿所述第一方向相对的两条触控信号线40在第一方向上具有静电保护距离。
示例性的,所述沿所述第一方向相对的两条触控信号线40中,其中一条触控信号线40属于第一组触控信号线41,另一条触控信号线40属于第二组触控信号线42。
示例性的,所述静电保护距离大于或等于10微米。示例性的,所述静电保护距离大于或等于20微米。具体的,所述静电保护距离可以为10微米、12微米、15微米、18微米、20微米、22微米。
上述设置方式增加了沿第一方向相对的两条触控信号线40之间的间距, 有效改善了沿第一方向相对的两条触控信号线40之间发生的ESD不良,同时保证了阵列基板应用于显示装置中时的显示和触控性能。
在一些实施例中,所述阵列基板还包括:多个像素电极52;所述静电保护距离L1满足:L1=k*H;H代表所述像素电极52在所述第一方向上的最大长度,2%≤k≤6%。
所述静电保护距离取值在2%H至6%H之间,可以包括2%H、3%H、4%H、5%H和6%H。
在设置所述静电保护距离满足上述条件时,增加了沿第一方向相对的两条触控信号线40之间的间距,有效改善了沿第一方向相对的两条触控信号线40之间发生的ESD不良,同时保证了阵列基板应用于显示装置中时的显示和触控性能。
如图7~图9、图11所示,在一些实施例中,设置至少部分所述触控信号线40包括多个直边部401和多个弯曲部402,所述直边部401与所述弯曲部402交替设置;在一条触控信号线40中,至少部分所述弯曲部402与所述像素电极52在所述基底10上的正投影交叠。
示例性的,同一条触控信号线40包括的多个直边部401和多个弯曲部402形成为一体结构。
示例性的,所述触控信号线40与所述数据线51同层同材料设置。
示例性的,所述触控信号线40与所述数据线51异层设置。
示例性的,所述触控信号线40采用金属材料制作。
示例性的,所述直边部401沿所述第一方向延伸。
示例性的,所述直边部401与所述数据线51平行。
示例性的,所述弯折部在所述基底10上的正投影与相邻的数据线51在所述基底10上的正投影之间的距离,大于所述直边部401在所述基底10上的正投影与相邻的数据线51在所述基底10上的正投影之间的距离。
示例性的,在同一条触控信号线40中,至少部分所述弯曲部402与所述像素电极52在所述基底10上的正投影交叠。
示例性的,所述弯折部在所述基底10上的正投影,与所述开关元件53 在所述基底10上的正投影不交叠。
上述设置方式有利于降低所述触控信号线40的布局难度,减小所述触控信号线40与阵列基板中的其他结构形成寄生电容。
如图7和图8所示,在一些实施例中,设置所述第一组触控信号线41中包括至少一条第一目标触控信号线,所述至少一条第一目标触控信号线靠近所述第二组触控信号线42的一端包括第一目标弯曲部4021;所述第二组触控信号线42中包括至少一条第二目标触控信号线,所述至少一条第二目标触控信号线靠近所述第一组触控信号线41的一端包括第二目标弯曲部4022;所述第一目标弯曲部4021与所述第二目标弯曲部4022之间具有第一保护距离L2,所述第一保护距离L2大于或等于所述静电保护距离L1。
示例性的,所述第一组触控信号线41中包括多条第一目标触控信号线,所述第二组触控信号线42中包括多条第二目标触控信号线,所述第一目标触控信号线与所述第二目标触控信号线一一对应,相对应的所述第一目标触控信号线和所述第二目标触控信号线沿所述第一方向相对设置。
相对应的所述第一目标触控信号线和所述第二目标触控信号线中,所述第一目标触控信号线靠近所述第二目标触控信号线的一端包括第一目标弯曲部4021,所述第二目标触控信号线靠近所述第一目标触控信号线的一端包括第二目标弯曲部4022,该第一目标弯曲部4021与该第二目标弯曲部4022沿所述第一方向正对,该第一目标弯曲部4021与该第二目标弯曲部4022沿第一方向具有所述第一保护距离L2。
示例性的,通过去除所述第一目标弯曲部4021靠近所述第二目标弯曲部4022的部分,使所述第一目标弯曲部4021与所述第二目标弯曲部4022之间具有所述第一保护距离L2。
上述设置方式增加了沿第一方向相对的两条触控信号线40之间的间距,有效改善了沿第一方向相对的两条触控信号线40之间发生的ESD不良,同时保证了阵列基板应用于显示装置中时的显示和触控性能。
值得注意,上述实施例提供的阵列基板中,在一条触控信号线40中,至少部分所述弯曲部402与所述像素电极52在所述基底10上的正投影交叠, 产生一个小的交叠电容,该交叠电容是像素存储电容Cst的一部分。由于为了克服上述提到的ESD问题,阵列基板中增加了沿第一方向相对的两条触控信号线40之间的间距,而该距离增加的较大时,会导致在所述中间区域附近像素电极52形成的交叠电容与其他位置不一致,容易造成显示不良。
如图7和图8所示,在一些实施例中,设置所述第一目标弯曲部4021在所述基底10上的正投影,与所述像素电极52在所述基底10上的正投影至少部分交叠;所述第一目标弯曲部4021包括延伸部4023,所述延伸部4023向远离所述第二组触控信号线42(即向远离所述第二目标弯曲部4022)的方向延伸。
示例性的,所述延伸部4023与所述第一目标弯曲部4021形成为一体结构。
示例性的,所述延伸部4023沿所述第二方向延伸。
示例性的,所述延伸部4023在所述基底10上的正投影与所述像素电极52在所述基底10上的正投影交叠。
需要说明,所述延伸部4023的尺寸可以根据实际需要设置,要能够保证该处子像素的Cst与其他位置的子像素的Cst大小保持一致。
上述设置方式在保证所述第一目标触控信号线和第二目标触控信号线之间具有静电保护距离L1的同时,对所述第一目标弯曲部4021与像素电极52之间的交叠面积做了补偿,保证了该处子像素的Cst与其他位置的子像素的Cst大小保持一致,降低了显示异常的风险。
另外,上述设置所述延伸部4023向远离所述第二组触控信号线42的方向延伸,使得触控信号线的端部(即延伸部4023的端部)远离所述第二目标弯曲部4022,避免端部相对引发静电击穿短路。
值得注意,如图8所示,所述第一目标弯曲部4021与所述延伸部4023接触的部分包括弯折部X,通过设置所述弯折部X,不仅使得所述第一目标弯曲部4021能够与开关元件53的第二极相距较远,避免所述第一目标弯曲部4021与开关元件53的第二极发生短路,还使得所述第一目标弯曲部4021更靠近栅线,有利于更好的提升像素开口率。
如图7和图8所示,在一些实施中,所述第一组触控信号线41中包括至少一条第三目标触控信号线,所述至少一条第三目标触控信号线靠近所述第二组触控信号线42的一端包括第一目标直边部4011;所述第二组触控信号线42中包括至少一条第四目标触控信号线,所述至少一条第四目标触控信号线靠近所述第一组触控信号线41的一端包括第二目标直边部4012;所述第一目标直边部4011与所述第二目标直边部4012之间具有第二保护距离L3,所述第二保护距离L3大于或等于所述静电保护距离L1。
示例性的,所述第一组触控信号线41中包括多条第三目标触控信号线,所述第二组触控信号线42中包括多条第四目标触控信号线,所述第三目标触控信号线与所述第四目标触控信号线一一对应,相对应的所述第三目标触控信号线和所述第四目标触控信号线沿所述第一方向相对设置。

上述设置方式增加了沿第一方向相对的两条触控信号线40之间的间距,有效改善了沿第一方向相对的两条触控信号线40之间发生的ESD不良,同时保证了阵列基板应用于显示装置中时的显示和触控性能。
在一些实施例中,所述第二保护距离L3大于所述第一保护距离L2。
值得注意,由于所述第一目标直边部4011和所述第二目标直边部4012不会对像素存储电容Cst产生影响,且所述第一目标直边部4011和所述第二目标直边部4012在所述中间区域有尖端相对,所以可以适当增加所述第二保护距离L3,示例性的,设置所述第二保护距离L3大于20微米,从而更好的降低所述第一目标直边部4011和所述第二目标直边部4012在所述中间区域发生ESD不良的风险。
而所述第一目标弯曲部4021和所述第二目标弯曲部4022在所述中间区 域没有尖端相对,所以所述第一保护距离L2可以设置相对较小的数值,同样也能够降低ESD不良的发生风险。

上述设置所述相邻的两条触控信号线40的正投影以及所述同一条数据线51的正投影,均包括位于相邻的触控电极300在所述基底上的正投影之间的部分,有效减小了触控信号线40对像素开口区的遮挡,从而很好的保证了像素开口率。
在一些实施例中,设置所述相邻的两条触控信号线40所在的层不同于所述同一条数据线51所在的层。
上述设置方式有利于避免所述触控信号线40与所述数据线51之间发生短路,保证了所述阵列基板的信赖性。
而且上述设置方式还可以缩小所述触控信号线40在所述基底10上的正投影,与所述数据线51在所述基底10上的正投影之间的距离,有利于降低触控信号线40的布局难度,进一步提升像素开口率。
如图10和图11所示,在一些实施例中,所述阵列基板还包括多条栅线50,所述栅线50的至少部分沿所述第二方向延伸;设置至少部分所述直边部401包括相耦接的第一子部4013和第二子部4014,在平行于所述基底10,且垂直于所述触控信号线40的延伸方向的方向上,所述第一子部4013的宽度b大于所述第二子部4014的宽度a;所述第一子部4013在所述基底10上的正投影,覆盖所述栅线50的至少部分侧面在所述基底10上的正投影;和/或,至少部分所述弯曲部402包括相耦接的第三子部4024和第四子部4025,在平行于所述基底10,且垂直于所述触控信号线40的延伸方向的方向上,所述第三子部4024的宽度b大于所述第四子部4025的宽度a;所述第三子部4024在所述基底10上的正投影,覆盖所述栅线50的至少部分侧面在所述基底10上的正投影。

如图14和图15所示,在一些实施例中,设置所述第三公共连接部54的第二端542在所述基底10上的正投影,与相邻的触控感测块30中的第二个触控感测块30包括第一公共连接部301在所述基底10上的正投影不交叠。
上述设置方式能够减少相邻触控感测块30之间产生的寄生电容,保证阵列基板工作的稳定性。
本公开实施例还提供了一种触控显示装置,包括上述阵列基板。
上述实施例提供的阵列基板中,将整个阵列基板划分为沿第一方向排布,且能够分别控制触控的两部分,这样在布局所述触控信号线40时,每条触控信号线40不必沿第一方向穿过整块阵列基板,只需穿过其对应的一组电极块所在区域即可,这样不仅降低了阵列基板中,触控信号线40所需的布局空间,有效降低了大尺寸阵列基板中触控信号线40的布局难度,而且还改善了布局所述触控信号线40时,对阵列基板中各子像素的开口率的影响。另外,上述设置方式使得整个阵列基板中的触控信号线40划分为两组,每组触控信号线40连接对应的控制单元,实现了阵列基板的双边驱动,从而很好的降低了触控信号线40与控制单元之间的连接难度。
因此,本公开实施例提供的触控显示装置在包括上述阵列基板时同样具有上述有益效果,此处不再赘述。
在一些实施例中,所述触控显示装置还包括:对向基板和液晶层,所述对向基板与所述阵列基板相对设置,所述液晶层位于所述对向基板与所述阵列基板之间。
示例性的,所述对向基板包括彩膜基板。
所述液晶层在所述像素电极52和公共电极的驱动下发生偏转,从而实现触控显示装置的显示功能。
需要说明的是,所述触控显示装置可以为:电视、显示器、数码相框、手机、平板电脑等任何具有显示功能的产品或部件。
需要说明,本说明书中的各个实施例均采用递进的方式描述,各个实施例之间相同相似的部分互相参见即可,每个实施例重点说明的都是与其他实施例的不同之处。尤其,对于方法实施例而言,由于其基本相似于产品实施 例,所以描述得比较简单,相关之处参见产品实施例的部分说明即可。
