Description

触控基板以及触控装置 技术领域

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
在研究中，本申请的发明人注意到，目前，存在ADS技术与内嵌式触控(in cell touch)技术相结合的趋势，但在如何降低触控电极之间的节点耦合电容的问题上，目前的in cell touch触控屏尚未出现具体的技术方案。
结合图1和图4所示，本发明实施例提供的触控基板，包括薄膜晶体管01、以及透明的公共电极层06和像素电极层05；所述公共电极层06包括沿第一方向延伸的公共电极18和触控驱动电极6，在所述公共电极18和触控 驱动电极6之间填充有绝缘介质56；所述触控基板上还设有与所述触控驱动电极6异层设置且沿第二方向延伸的触控感应电极4，该触控感应电极4覆盖所述公共电极18和触控驱动电极6之间的间隙区域11；在一帧画面的显示时间内，所述触控驱动电极6用于分时地传递公共电极信号和触控扫描信号。
在实际应用中，可以进行如图1所示的设置以形成液晶显示装置。例如，图1中，衬底基板1上可以设置有彩膜层14(例如，包括红色子像素R、绿色子像素G和蓝色子像素B)、黑矩阵2以及OC(Overcoating)层3等结构以形成彩膜基板；衬底基板8上除了包括栅极15、源极16、漏极17的薄膜晶体管01以外，还设置有与栅极15相连的栅线(图1中未示出)、与源极16相连的数据线(图1中未示出)、触控驱动电极6、与漏极17相连的像素电极5、以及触控感应电极4等结构以形成阵列基板；彩膜基板与阵列基板对盒后形成液晶盒。在所述液晶盒中，对盒的彩膜基板与阵列基板之间填充有液晶13。
图1所示的液晶显示装置是以基于ADS型阵列基板为例的；在图1中，公共电极层、像素电极层和触控感应电极依次设置在衬底基板8上，其中公共电极层更靠近衬底基板。进一步地，例如，公共电极层为板状电极层，像素电极层为狭缝电极层。
在上述液晶显示装置的结构中，具有触控驱动电极6和触控感应电极4的阵列基板即为触控基板。
例如，在上述触控基板上形成有异层设置的栅线10和数据线9；所述触控驱动电极6包括沿栅线10方向延伸且相连接的多个子电极61(例如菱形电极)，所述公共电极18包括多个位于所述触控驱动电极之间的子电极181(例如菱形电极)；所述触控感应电极4包括沿数据线9方向延伸且相连接的多个子框状电极41(例如，菱形框状电极)。
或者，例如，触控驱动电极6包括沿数据线9方向延伸且相连接的多个子电极，公共电极18包括多个位于触控驱动电极6之间的子电极；触控感应电极4包括沿栅线10方向延伸且相连接的多个子框状电极。
本发明实施例中，触控驱动电极包括的子电极、公共电极包括的子电极以及触控感应电极包括的子框状电极可以为菱形，也可以为其他多边形形状， 本发明以下实施例及附图中以菱形为例进行说明。
结合附图3所示，例如，触控驱动电极6的结构可以是将由透明金属氧化物(例如，ITO，氧化铟锡)材料形成的公共电极层的全部或部分电极分割成若干条状电极，将分割出的条状电极作为触控驱动电极6。进行触控时，触控驱动电极6作为驱动电极使用；进行显示时，触控驱动电极6作为公共电极使用。
在作为公共电极层的全部或部分电极中，还挖出将触控驱动电极6与一部分电极相隔离的间隙区域11，被间隙区域11所隔离出的电极(即被间隙区域11所包围的电极)如图3中的公共电极18所示，呈浮岛状(例如，可以为菱形、其它多边形等)，固定作为常态的公共电极使用。
触控驱动电极6与常态的公共电极18之间可以不具有特定的设置关系，而是在作为公共电极的全部或部分电极上随意设置有触控驱动电极6以及常态的公共电极18。当然，基于工艺的考虑，也可以针对触控驱动电极6与公共电极18应用具体的设计规则，如：逐行间隔设置驱动电极6与公共电极18。
通常，触控驱动电极6以及常态的公共电极18上均设置有一定数量的过孔12，过孔12可以同与栅极同层设置的连接线相连，以降低电阻。
例如，在本发明的至少一个实施例中，公共电极18的多个菱形电极通过与栅线同层设置的公共电极线7进行连接；和/或，触控驱动电极6通过过孔12与连接电极62相连，该连接电极62与栅线同层设置。
在本发明的实施例中，触控感应电极4覆盖公共电极和触控驱动电极之间的间隙区域11。
例如，在间隙区域11中，可以设置如图4所示的触控感应电极4，不同触控感应电极4之间可以通过连接桥19相连。通常，触控驱动电极6可以按行设置，触控感应电极4可以按列设置。间隙区域11呈菱形框等多边形框状，设置于间隙区域11中的触控感应电极4则通常也呈菱形框等多边形框状。
需要说明的是，例如，触控感应电极4的多个菱形框状电极除了覆盖所述公共电极和触控驱动电极之间的间隙区域之外，还覆盖所述公共电极的部分区域。也就是说，在保证不增加触控感应电极4和触控驱动电极6的交叠区域的前提下，可以将触控感应电极4向内部扩展，即：增加触控感应电极 4的内缩距离。
触控感应电极4的材质要保证电阻尽量小，比如：方阻小于1的材料，通常为金属。
将图4中的触控感应电极4进行局部放大后得到图2所示的结构。从图2中可以看到，像素电极层包括呈矩阵排列的多个像素电极；触控感应电极4包括横纵交错且相互连接的金属网格线，横向延伸的所述金属网格线位于相邻的两行像素电极之间，纵向延伸的所述金属网格线位于相邻的两列像素电极之间。这样设置触控感应电极，既可以利用电阻率较低的金属材料来制作触控感应电极，又不会影响到像素单元的开口率。
本发明的至少一个实施例还提供了一种触控装置，其包括前述实施例中的触控基板。
例如，如图5所示，上述触控装置包括触控基板100，还包括与触控基板100相对设置的对向基板200，该对向基板200上设有彩膜层14和黑矩阵2；所述触控基板100上的触控感应电极4在该对向基板上的投影位于黑矩阵区域内。
在本发明的实施例及其对应附图中，是以液晶显示装置为例来介绍触控基板及触控装置的。本发明实施例所提供的触控基板除了可以应用在液晶显示装置中，也可以作为OLED(有机发光二极管)的背板从而实现具备触控功能的OLED设备。
本发明实施例提供的触控基板及触控装置中，在ADS技术与in cell touch技术相结合的情况下，触控驱动电极、触控感应电极的设置方式是一种可行性较高的in Cell touch方案。由于触控驱动电极与触控感应电极之间不存在正对面积，降低了触控驱动电极与触控感应电极之间的耦合，因此本发明实施例能够最大限度地降低触控电极节点电容，保证RC延迟满足IC设计要求。另外，由于触控驱动电极与触控感应电极均设置在同一个触控基板上，因此最大限度地降低了IC匹配难度，有利于将显示装置的驱动IC和触控IC的整合，实现单片(One Chip)设置，以便适应显示装置的未来发展需要，提高产品市场竞争力。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
本申请要求于2014年12月29日递交的中国专利申请第201410848506.8号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
