Description

阵列基板及触控显示器
本发明要求2016年7月18日递交的发明名称为“阵列基板及触控显示器”的申请号201610566408.4的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及触控领域，具体涉及触控显示领域，尤其涉及一种阵列基板及触控显示器。
背景技术
随着智能手机市场竞争的激烈化程度的日渐加深，触控显示一体化(简称，触显一体化)产品迎来了新一轮的竞逐。Incell技术被视为该领域的高端技术，广受追捧。所谓的incell技术，是指将触控面板功能嵌入到液晶像素中。
目前的自容式触控技术方案中，通常将公共电极进行切割，从而形成矩阵状分布的多个感测单元(sensor)，多个感测单元中相邻的感测单元之间存在切割狭缝。为降低感测单元(sensor)与触控引线之间的电容，会以子像素为单元，在触控引线处的公共电极上进行挖缝，由于多个感测单元中相邻的感测单元之间存在切割狭缝，当数据线(data line)在进行信号传输时产生的电场穿过感测单元之间的切割狭缝时，会对切割狭缝处对应的液晶产生影响，干扰此处的液晶的转向，造成该位置漏光，也加大了出现条状波纹(Mura)的风险，影响内嵌式触控显示器的光学品质。
发明内容
本发明的目的在于提供一种阵列基板，该阵列基板能够有效降低漏光风险，同时也可以避免竖直条状波纹不良的产生。
本发明的另一目的在于提供一种采用上述阵列基板的触控显示器。
为了实现上述目的，本发明实施方式提供如下技术方案：
本发明提供一种阵列基板，至少包括基板、依次层叠设置所述基板上的公 共电极层、绝缘层及感测层，所述公共电极层包括多个触控电极，所述多个触控电极间隔设置，所述感测层上对应每一个触控电极均设有触控引线及悬浮引线，所述触控引线通过第一过孔与触控电极电连接，所述悬浮引线与所述触控引线间隔且并列设置，并且所述悬浮引线通过第二过孔与触控电极电性连接。
其中，所述多个触控电极阵列排布，每一所述触控电极分别对应两条或者两条以上触控引线和一条悬浮引线。
其中，对应于同一所述触控电极的多条触控引线并列排布，每条所述触控引线通过多个第一过孔与所述触控电极电性连接。
其中，对应于同一所述触控电极的多条触控引线与所述悬浮引线并列排布且延伸方向相同。
其中，多个所述触控电极的悬浮引线彼此绝缘，并且每条所述悬浮引线通过第二过孔与相应的所述触控电极电性连接。
其中，所述阵列基板还包括触控驱动单元和外围引线，每个所述触控电极通过所述外围引线连接至所述触控驱动单元。
其中，每一所述触控电极对应的触控引线与所述外围引线电性相连。
其中，所述感测层为绝缘层，所述触控引线与所述悬浮引线为设于绝缘层上的金属走线。
其中，所述阵列基板还包括交叉排布于基板上的栅极线及数据线，所述触控引线位于所述栅极线上方并与其绝缘。
本发明提供触控显示器，包括所述的阵列基板。
本发明实施例具有如下优点或有益效果：
本发明中，通过将悬浮引线与触控电极通过过孔电性连接的方法，从而减少了引挖缝漏光而产生的电场差异，避免了位于触控电极下方的数据线(Data line)形成的电场会经触控电极之间区域窜入到上方的液晶层，形成水平方向的电场，驱动液晶翻转，从而导致造成该位置漏光，出现条状波纹(Mura)现象的发生。

此外，在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。若本说明书中出现“工序”的用语，其不仅是指独立的工序，在与其它工序无法明确区别时，只要能实现该工序所预期的作用则也包括在本用语中。另外，本说明书中用“～”表示的数值范围是指将“～”前后记载的数值分别作为最小值及最大值包括在内的范围。在附图中，结构相似或相同的用相同的标 号表示。
请参阅图1～图2，本发明的阵列基板100包括：基板10、公共电极层(图未编号)、绝缘层30和感测层40，所述公共电极层形成于所述基板10上，所述绝缘层30涂覆且覆盖在所述公共电极层，所述感测层40形成于所述绝缘层30之背离基板10的表面。所述公共电极层包括多个触控电极21，所述多个触控电极21间隔设置。所述感测层40上对应每一个触控电极21均设有触控引线41及悬浮引线42，所述触控引线41通过第一过孔31与触控电极21电连接，所述悬浮引线42与所述触控引线41间隔且并列设置，并且通过第二过孔32与触控电极21电性连接。所述感测层为绝缘层，所述触控引线与所述悬浮引线为设于绝缘层上的金属走线。
具体的，所述感测层40包括多条触控引线41和多条悬浮引线42。所述触控引线41正对所述触控电极21设置，换言之，触控引线41在基板10上的正投影大部分位于触控电极21上。所述触控引线41通过设置在绝缘层30上的第一过孔31与所述触控电极21电性连接。所述悬浮引线42设置在绝缘层30上位于内一个触控电极21内，与相应的触控引线均匀排布，并且悬浮引线42与相应的触控电极21通过第二过孔32连接。本实施例中，一个触控电极连接有两个并联的触控引线，该触控电极内的与触控引线41相匹配的有一个悬浮引线42位于该触控引线41的一侧。其它实施方式中，一个触控电极41也可以设有一个触控引线。阵列基板还包括像素电极，像素电极位于触控引线41与悬浮引线42之间的位置。所述阵列基板还包括交叉排布于基板10上的栅极线及数据线，所述触控引线41位于所述栅极线上方并与其绝缘。
本发明中，通过将悬浮引线与触控电极电性连接的方法，从而减少了引挖缝漏光而产生的电场差异，避免了位于触控电极下方的数据线(Data line)形成的电场会经触控电极之间区域窜入到上方的液晶层，形成水平方向的电场，驱动液晶翻转，从而导致造成该位置漏光，出现条状波纹(Mura)现象的发生。
为验证本发明的技术效果，将悬浮引线连接至触控电极(sensor)和悬浮引线不连接至触控电极(sensor-f)两种情况在模拟软件中进行模拟，并得到暗态时的Pixel光学模拟结果如下表所示：
Figure PCTCN2016092710-appb-000001
将上表中数据在坐标轴中标出，请结合参阅图4，图中横轴表示视角，纵轴表示光线亮度相对值。例如，当视角为60度时，悬浮引线连接至触控电极(sensor)时的亮度相对值为0.447；当悬浮引线不连接至触控电极时的亮度相对值为0.612。也就是说悬浮引线连接至触控电极比悬浮引线不连接至触控电极的亮度下降了34％，从而能有效降低漏光。从图中也可以看出，无论哪种视角下，将悬浮引线不连接至触控电极时，Pixel暗态的亮度均比悬浮引线连接至触控电极时的亮度更高，即光学漏光的风险更高。通过本发明能够有效降低了显示时的光学漏光风险，有利于改善显示时的Mura不良。
本发明的一个具体的实施例中，所述多个触控电极21呈阵列排布，每一所述触控电极21分别对应两条或者两条以上触控引线41和一条悬浮引线42，对应于同一触控电极21的所述多条触控引线41并排设置，所述悬浮引线42的延伸方向与对应同一电极的所述多条触控引线41的延伸方向相同。也就是说，所述悬浮引线42的个数与所述触控电极21的个数相同。优选的，对应于不同触控电极21的多个悬浮引线42之间相互绝缘。每条所述触控引线41通过多个第一过孔与所述触控电极21电性连接。进一步的，多个所述触控电极21的悬浮引线42彼此绝缘，并且每条所述悬浮引线42通过第二过孔与相应的所述触控电极21电性连接。
在本实施例的一个可选实现方式中，每个触控电极21的两个触控引线41之间设有一个悬浮引线42。需要说明的是，触控电极21和悬浮引线42形成的具体图案样式，可以由用户根据实际情况自行设定，本申请对此不做限制。
进一步的，所述阵列基板还包括触控驱动单元和外围引线，每个所述触控电极通过所述外围引线连接至所述触控驱动单元。每一所述触控电极对应的触控引线与所述外围引线电性相连。
本发明的一个具体的实施例中，阵列基板100还包括触控驱动单元50和外围引线60，所述外围引线60与所述触控电极21一一对应，每个所述触控电极21通过所述外围引线60电性连接至所述触控驱动单元50。进一步具体的，每个触控电极21对应的多条触控引线41中，至少有两条触控引线41并联后连接外围引线60，并通过所述外围引线60连接至触控驱动单元50。设置多条触控引线41与所述外围引线60连接可以提高连接的稳定性，降低由于单条触控引线41断开造成的故障。
进一步，触控驱动单元50在触控阶段，可以在触控电极21上施加一个脉冲信号，以便通过触控电极21探测手指的触摸位置。在显示阶段，触控电极212可以被复用公共电极，即触控驱动单元50可以在触控引线41和悬浮引线42上施加一个恒压信号，使得液晶分子可以在公共电极和像素电极的共同作用下发生偏转，从而实现显示功能。
在本实施例的一个可选实现方式中，触控引线41、第一引线43和悬浮引线42采用同种材料。在本发明实施例中，所述触引线41的材料为透明导电材料或者金属材料。优选为触控引线41的材料选为透明导电材料，例如：氧化铟锡(Indium Tin Oxide，简称ITO)、氧化铟锌(Indium Zinc Oxide，简称IZO)或者两者的组合等。
优选的，触控电极21的材料可以为透明的导电材料，例如氧化铟锡(Indium Tin Oxide，简称ITO)、氧化铟锌(Indium Zinc Oxide，简称IZO)或者两者的组合等。在制作触控电极21时，可以首先使用上述透明的导电材料形成一个导电层，然后通过刻蚀等工艺步骤在该导电层上形成一定的电极图案。通过这个电极图案，就可以得到触控电极21。
基于上述提供的阵列基板100，参阅图3，本发明还提供了一种触控显示器200。在本实施例中，触控显示器包括上述任一实施例中所描述的阵列基板100以及与阵列基板100对置设置的彩膜基板101，在阵列基板100与彩膜基板101之间设置有一个液晶层102。彩膜基板上101设置有彩膜层图未示 出，并且彩膜层设置于彩膜基板101面向液晶层102一侧。
基于上述提供的触控显示器200，本发明还提供了一种电子装置，所述电子装置包括但不限于为：电子纸、液晶电视、移动电话、数码相框、平板电脑等任何具有触控显示功能的产品或部件。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
