Abstract

本发明公开了一种内嵌式触摸屏、其驱动方法及显示装置,由于将透明导电层分割成第二触控电极和公共电极,相当于将现有的整面连接的公共电极层进行分割,形成相互绝缘的第二触控电极和公共电极,在显示时,对第二触控电极和公共电极均加载公共电极信号,在触控时,对第一触控电极或第二触控电极加载触控扫描信号,第二触控电极或第一触控电极耦合触控扫描信号并输出,通过分时驱动实现触控功能和显示功能。由于本发明实施例提供的内嵌式触摸屏是对现有公共电极层结构进行变更制作第二触控电极,因此,在现有制备工艺的基础上,不需要增加额外的工艺单独制备第二触控电极,节省了生产成本,提高了生产效率。

Description

一种内嵌式触摸屏、其驱动方法及显示装置
技术领域
本发明涉及触控技术领域,尤指一种内嵌式触摸屏、其驱动方法及显示装置。
背景技术
随着显示技术的飞速发展,触摸屏(Touch Screen Panel)已经逐渐遍及人们的生活中。目前,触摸屏按照组成结构可以分为:外挂式触摸屏(Add on ModeTouch Panel)、覆盖表面式触摸屏(On Cell Touch Panel)、以及内嵌式触摸屏(InCell Touch Panel)。其中,外挂式触摸屏是将触摸屏与液晶显示屏(Liquid CrystalDisplay,LCD)分开生产,然后贴合到一起成为具有触摸功能的液晶显示屏,外挂式触摸屏存在制作成本较高、光透过率较低、模组较厚等缺点。而内嵌式触摸屏将触摸屏的触控电极内嵌在液晶显示屏内部,可以减薄模组整体的厚度,又可以大大降低触摸屏的制作成本,受到各大面板厂家青睐。
目前,现有的内嵌(In cell)式触摸屏主要是利用互电容的原理实现检测手指触摸位置。在具体实施时,是在现有的TFT(Thin Film Transistor,薄膜场效应晶体管)阵列基板上直接另外增加触控扫描线和触控感应线实现的,即在TFT阵列基板的表面制作两层相互异面相交的透明导电电极,一般为条状ITO电极,这两层ITO(Indium Tin Oxides,铟锡金属氧化物)电极分别作为触摸屏的触控驱动线和触控感应线,在两条ITO电极的异面相交处形成感应电容。其工作过程为:在对作为触控驱动线的ITO电极加载触控驱动信号时,检测触控感应线通过感应电容耦合出的电压信号,在此过程中,有人体接触触摸屏时,人体电场就会作用在感应电容上,使感应电容的电容值发生变化,进而改变触控感应线耦合出的电压信号,根据电压信号的变化,就可以确定触点位置。
上述内嵌式触摸屏的结构设计,需要在现有的TFT阵列基板上增加新的膜层,导致在制作TFT阵列基板时需要增加新的工艺,使生产成本增加,不利于提高生产效率。
发明内容
有鉴于此,本发明实施例提供的一种内嵌式触摸屏、其驱动方法及显示装置,用以实现成本较低、生产效率较高的内嵌式触摸屏。
因此,本发明实施例提供了一种内嵌式触摸屏,包括相对而置的第一基板和第二基板;还包括:设置于所述第一基板面向所述第二基板的一侧的透明导电层,与所述透明导电层绝缘且异层设置的多个第一触控电极;其中,

具体实施方式
下面结合附图,对本发明实施例提供的内嵌式触摸屏、其驱动方法及显示装置的具体实施方式进行详细地说明。
附图中各膜层的厚度和形状不反映真实比例,目的只是示意说明本发明内容。
本发明实施例提供了一种内嵌式触摸屏,如图1所示,包括相对而置的第一基板1和第二基板2;还包括:设置于第一基板1面向第二基板2的一侧的透明导电层3,与透明导电层3绝缘且异层设置的多个第一触控电极01;其中,
如图2a和图2b所示,透明导电层3被分割成呈矩阵排列的多个相互独立的子电极;其中,
如图2a所示,位于奇数行或偶数行的子电极为第二触控子电极021,位于偶数行或奇数行的子电极为公共电极03,且位于同一列的第二触控子电极021组成一第二触控电极02;或者,如图2b所示,在具体实施时,位于奇数列或偶数列的子电极为第二触控子电极02,位于偶数列或奇数行列的子电极为公共电极03,且位于同一行的第二触控子电极021组成一第二触控电极02;
第一触控电极01的延伸方向与第二触控电极02的延伸方向垂直,且各第一触控电极01分别与与第二触控电极02垂直的一行或一列公共电极03相对设置;
第一触控电极01为触控驱动电极,第二触控电极02为触控感应电极;或第一触控电极01为触控感应电极,第二触控电极02为触控驱动电极。
本分发明实施例提供的上述内嵌式触摸屏,由于将透明导电层分割成第二触控电极和公共电极,相当于将现有的整面连接的公共电极层进行分割,形成相互绝缘的第二触控电极和公共电极,在显示时,对第二触控电极和公共电极均加载公共电极信号,在触控时,对第一触控电极或第二触控电极加载触控扫描信号,第二触控电极或第一触控电极耦合触控扫描信号并输出,通过分时驱动实现触控功能和显示功能。由于本发明实施例提供的内嵌式触摸屏是对现有公共电极层结构进行变更制作第二触控电极,因此,在现有制备工艺的基础上,不需要增加额外的工艺单独制备第二触控电极,节省了生产成本,提高了生产效率。
并且,上述内嵌式触摸屏,将透明导电层分割成呈矩阵排列的多个相互独立的子电极,不仅可以保证整个触摸屏的子电极分布均匀,并且由于组成公共电极的子电极与组成第二触控电极的子电极结构相同,因此还可以保证公共电极与第二触控子电极的负载相匹配。另外,将第一触控电极设置与与公共电极相对的位置,避免第一触控电极与第二触控电极有交叠区域,从而可以最大限度的降低第一触控电极与第二触控电极之间的耦合电容。
在具体实施时,在本发明实施例提供的上述内嵌式触摸屏中,为了不影响正常的显示功能,在对透明导电层进行分割时,分割线一般都会避开显示的开口区域,设置在黑矩阵层的图形区域,即各子电极之间的间隙在第一基板上的正投影一般会位于亚像素之间的间隙处。
具体地,在具体实施时,本发明实施例提供的上述内嵌式触摸屏,第一基板可以为阵列基板,第二基板为对向基板;当然第一基板也可以为对向基板,第二基板为阵列基板,在此不作限定。
进一步地,在具体实施时,本发明实施例提供的上述内嵌式触摸屏,第一触控电极和第二触控电极可以均设置与同一基板上,也可以分别设置于不同基板上,在此不作限定。较佳地,在本发明实施例提供的上述内嵌式触摸屏中,如图1所示,各第一触控电极01设置于第二基板2面向第一基板1的一侧。
本发明实施例提供的上述内嵌式触摸屏,既适用于扭转向列(TwistedNematic,TN)型液晶显示屏,也适用于高级超维场开关(Adwanced DimensionSwitch,ADS)型液晶显示屏、高开口率高级超维场开关(High-AdwancedDimension Switch,HADS)型液晶显示屏和平面内开关(In-Plane Switch,IPS)型液晶显示屏。
进一步地,在本发明实施例提供的上述内嵌式触摸屏应用于ADS型液晶显示屏时,板状结构的公共电极层位于狭缝状像素电极的下方,即公共电极位于下基板与像素电极之间,并且在公共电极与像素电极之间还设置有绝缘层。而应用于HADS型液晶显示屏时,狭缝状的公共电极位于板状结构的像素电极的上方,即像素电极位于下基板与公共电极之间,并且在像素电极与公共电极之间还设置有绝缘层。
在具体实施时,本发明实施例提供的上述内嵌式触摸屏,更适用于ADS型或HADS型液晶显示屏,这样将现有技术中位于阵列基板上的公共电极层进行分隔形成上述公共电极与第二触控电极。
进一步地,在本发明实施例提供的上述内嵌式触摸屏中,第一触控电极的材料可以金属材料,也可以为透明导电材料,在此不作限定。
进一步地,在具体实施时,在本发明实施例提供的上述内嵌式触摸屏中,当第一触控电极的材料为透明导电材料时,由于不需要考虑开口率的问题,因此,如图2a和图2b所示,可以将第一触控电极01设置成覆盖一行或一列公共电极03的面电极结构,当然也可以设置成如图3a所示的多条条状结构,或者如图3b所示的网格状结构,在此不作限定。
在具体实施时,在本发明实施例提供的上述内嵌式触摸屏中,当第一触控电极的材料为金属材料时,由于金属材料大多不透光,会影响开口率,需要尽量减小第一触控电极的投影面积,因此如图3a所示,各第一触控电极01可以由多条条状第一触控子电极011组成;或者如图3b所示,各第一触控电极01为网格状结构。较佳地,各第一触控由多条条状第一触控子电极组成的触控效果较佳。
进一步地,当第一触控电极的材料为金属材料时,为了避免第一触控电极影响开口率,在本发明实施例提供的上述内嵌式触摸屏中,嵌式触摸屏还可以包括:位于第一基板面向第二基板一侧,或第二基板面向第一基板一侧的黑矩阵层;
各第一触控电极的图形在第一基板的正投影位于黑矩阵层的图形所在的区域内。
进一步地,在具体实施时,当本发明实施例提供的上述内嵌式触摸屏应用于ADS型或HADS型液晶显示屏时,即第一基板为阵列基板,第二基板为对向基板;如图2a和图2b所示,内嵌式触控屏还可以包括:
位于第一基板1面向第二基板2一侧、且与透明导电层3异层设置的公共电极线04和导线05;其中,公共电极03通过过孔与对应的公共电极线04电连接,第二触控电极02通过过孔与对应的导线05电连接。
较佳地,为了降低公共电极与公共电极线之间的接触电阻,公共电极可以通过多个过孔与公共电极线电连接,同理,第二触控电极也可以通过多个过孔与导线电连接,在此不作限定。
较佳地,为了简化制作工艺,进一步降低生产成本,在本发明实施例提供的上述内嵌式触摸屏中,导线与公共电极线同层设置,且导线和公共电极线的延伸方向均与第二触控电极的延伸方向相同。这样在制备时,将导线与公共电极线同层设置,可以不用增加新的制备工艺,仅需变更对应的膜层的构图即可制得导线与公共电极线,简化了工艺步骤,节省了生产成本,提高了生产效率。并且,导线和公共电极线的延伸方向均设置为与第二触控电极的延伸方向相同,不仅可以便于导线与第二触控电极的连接,并且可以保证导线与公共电极线不会交叉,避免电极间发生串扰。
较佳地,为了简化制作工艺,进一步降低生产成本,在本发明实施例提供的上述内嵌式触摸屏中,还包括:如图4a和图4b所示,设置于第一基板1面向第二基板2的一侧呈矩阵排列的多个亚像素4、以及相互交叉而置的栅极信号线G和数据信号线D;
导线05的延伸方向与栅极信号线G相同,或与数据信号线D相同。这样将导线和公共电极线的延伸方向设置为与栅极信号线相同,或与数据信号线相同,使导线和公共电极线位于显示屏的显示区域,不用占用边框区域,从而可以最大程度的降低显示屏的边框宽度,有利于实现窄边框设计。
较佳地,在具体实施时,在本发明实施例提供的上述内嵌式触摸屏中,如图4a所示,相邻行的亚像素4之间设置有两条栅极信号线G;且以每相邻的两列亚像素4为一个像素组,共用一条位于该两列亚像素4之间的数据信号线D;
导线05和公共电极线04交替设置在相邻的像素组之间的间隙处,且与数据信号线D同层设置。这样,通过双栅设计,可以节省出相邻像素组之间数据信号线的位置。从而将导线05与公共电极线04交替设置在相邻的像素组之间的间隙处,并且导线05和公共电极线04分别通过对应的过孔V与对应的第二触控电极02和公共电极03电连接。
或者,在具体实施时,在本发明实施例提供的上述内嵌式触摸屏中,如图4b所示,相邻列的亚像素4之间设置有两条数据信号线D;且以每相邻的两行亚像素4为一个像素组,共用一条位于该两行亚像素之间的栅极信号线G;
导线05和公共电极线04交替设置在相邻的像素组之间的间隙处,且与栅极信号线G同层设置。这样,通过双源设计,可以节省出相邻像素组之间栅极信号线的位置。从而将导线05与公共电极线04交替设置在相邻的像素组之间的间隙处,并且导线05和公共电极线04分别通过对应的过孔V与对应的第二触控电极02和公共电极03电连接。
具体地,在具体实施时,第一触控电极与相邻的第二子触控电极之间的间隙宽度会直接影响触控变化率,因此,第一触控电极与相邻的第二子触控电极之间的间隙宽度要保证触控电容变化量的同时,满足变化率的要求。较佳地,在本发明实施例提供的上述内嵌式触摸屏中,第一触控电极与相邻的触控电极之间的间隙宽度对应三个亚像素。
基于同一发明构思,本发明实施例还提供了一种上述内嵌式触摸屏的驱动方法,如图5所示,可以包括:在一帧时间内,分时进行显示扫描和触控扫描;其中:
S501、在显示扫描时间段,对透明导电层中的所有子电极施加公共电极信号;
S502、在触控扫描时间段,对触控驱动电极加载触控扫描信号,触控感应电极耦合触控扫描信号并输出。
具体地,在具体实施时,针对一帧时间段,步骤S501和步骤S502的执行顺序不进行限制,可以是先显示扫描时间段,后触控扫描时间段,也可以先触控扫描时间段后显示扫描时间段,在此不作限制,只要保证每一帧时间内,S501和S502的执行顺序相同就可以。
基于同一发明构思,本发明实施例还提供了一种显示装置,包括本发明实施例提供的上述内嵌式触摸屏,该显示装置可以为:手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。该显示装置的实施可以参见上述内嵌式触摸屏的实施例,重复之处不再赘述。
本发明实施例提供的一种内嵌式触摸屏、其驱动方法及显示装置,由于将透明导电层分割成第二触控电极和公共电极,相当于将现有的整面连接的公共电极层进行分割,形成相互绝缘的第二触控电极和公共电极,在显示时,对第二触控电极和公共电极均加载公共电极信号,在触控时,对第一触控电极或第二触控电极加载触控扫描信号,第二触控电极或第一触控电极耦合触控扫描信号并输出,通过分时驱动实现触控功能和显示功能。由于本发明实施例提供的内嵌式触摸屏是对现有公共电极层结构进行变更制作第二触控电极,因此,在现有制备工艺的基础上,不需要增加额外的工艺单独制备第二触控电极,节省了生产成本,提高了生产效率。并且,上述内嵌式触摸屏,将透明导电层分割成呈矩阵排列的多个相互独立的子电极,不仅可以保证整个触摸屏的子电极分布均匀,并且由于组成公共电极的子电极与组成第二触控电极的子电极结构相同,因此还可以保证公共电极与第二触控子电极的负载相匹配。另外,将第一触控电极设置与与公共电极相对的位置,避免第一触控电极与第二触控电极有交叠区域,从而可以最大限度的降低第一触控电极与第二触控电极之间的耦合电容。
显然,本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
