Abstract

本发明公开了一种触摸显示面板、其检测方法及显示装置,公共电极层被分割成多个相互独立的自电容电极,利用公共电极复用为自电容电极,不需要增加额外的膜层,仅需要将现有液晶显示屏中的公共电极层图形进行变更,节省了生产成本,提高了生产效率。由于上述触摸显示面板中的自电容电极是利用公共电极层分割形成,因此还包括与自电容电极异层且绝缘设置、且至少覆盖部分相邻自电容电极之间的分割间隙的补偿电极,补偿电极用于在显示时间段加载公共电极信号。这样在显示时,利用在补偿电极上加载的公共电极信号可以补偿自电容分割间隙处的公共电极信号,从而保证分割间隙处液晶正常翻转,保证整个显示面板显示正常。

Description

一种触摸显示面板、其检测方法及显示装置
技术领域
本发明涉及触控技术领域,尤其涉及一种触摸显示面板、其检测方法及显示装置。
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 Mode Touch Panel)、覆盖表面式触摸屏(On Cell Touch Panel)、以及内嵌式触摸屏(In Cell Touch Panel)。其中,外挂式触摸屏是将触摸屏与液晶显示屏(Liquid Crystal Display,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)式触摸屏是利用互电容或自电容的原理实现检测手指触摸位置。其中,利用自电容的原理可以在触摸屏中设置多个同层设置且相互绝缘的自电容电极,当人体未触碰屏幕时,各自电容电极所承受的电容为一固定值,当人体触碰屏幕时,对应的自电容电极所承受的电容为固定值叠加人体电容,触控侦测芯片在触控时间段通过检测各自电容电极的电容值变化可以判断出触控位置。由于人体电容可以作用于全部自电容,相对于人体电容仅能作用于互电容中的投射电容,由人体碰触屏幕所引起的触控变化量会大于利用互电容原理制作出的触摸屏,因此,相对于互电容的触摸屏能有效提高触控的信噪比,从而提高触控感应的准确性。
发明内容
有鉴于此,本发明实施例提供一种触摸显示面板、其检测方法及显示装置,用以避免由于自电容电极之间存在间隙导致的显示异常问题,从而提高触摸显示面板的显示效果。
因此,本发明实施例提供的一种触摸显示面板,包括:相对而置的上基板和下基板,位于所述上基板与所述下基板之间的液晶层,相互绝缘的像素电极和公共电极层,以及多条导线;其中,所述公共电极层被分割成多个相互独立的自电容电极,且各所述自电容电极与对应的导线连接;还包括:

较佳地,在本发明实施例提供的上述触摸显示面板,所述自电容电极位于所述下基板面向所述上基板一侧,所述公共电极位于所述像素电极上方,所述补偿电极位于所述公共电极上方。
较佳地,在本发明实施例提供的上述触摸显示面板,各所述导线与所述自电容电极异层设置,且各所述导线通过过孔与对应的自电容电极连接。
较佳地,在本发明实施例提供的上述触摸显示面板,各所述导线在所述下基板的正投影均位于所述黑矩阵层的图形所在区域内。
较佳地,在本发明实施例提供的上述触摸显示面板,还包括:与各所述导线电连接的触控侦测芯片;其中,
所述触控侦测芯片用于在显示时间段对各所述自电容电极和所述补偿电极加载公共电极信号,在触控时间段通过检测各所述自电容电极的电容值变化以判断触控位置。
较佳地,在本发明实施例提供的上述触摸显示面板,所述补偿电极为与各所述自电容电极均存在预设大小的交叠区域的一体结构。
相应地,当所述补偿电极为与各所述自电容电极均存在预设大小的交叠区域的一体结构时,本发明实施例还提供了一种上述触摸显示面板的检测方法,包括:
在所述触摸显示面板与驱动芯片绑定前,采用激光熔接技术,将位于所述补偿电极与各自电容电极的各交叠区域的所述补偿电极与所述自电容电极连接;

具体实施方式
下面结合附图,对本发明实施例提供的触摸显示面板、其检测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。
在内嵌式触摸屏应用于液晶显示屏时,一般采用公共电极复用为自电容电极,即将整面设置的公共电极分隔成若干相互独立自电容电极,自电容电极的具体结构如图1所示,公共电极被分隔成若干相互独立自电容电极1,相邻自电容电极1之间通过间隙相互绝缘,每一个自电容电极1通过单独的引出线与触控侦测芯片连接,每条引出线具体包括:将自电容电极1连接至触摸屏的边框处的导线2,以及设置在边框处用于将自电容电极1导通至触控侦测芯片的接线端子3的周边走线4。
液晶显示屏是通过利用公共电极与像素电极之间的电场控制液晶翻转实现显示,发明人经研究发现,上述内嵌式触摸屏,由于公共电极被分隔成若干相互独立的自电容电极,即相邻自电容电极之间的间隙处不存在公共电极,因此在显示时间隙处的液晶反转会出现异常,从而影响整个显示屏幕的显示效果。
本发明实施例提供的一种触摸显示面板,如图2a和图2b所示,包括:相对而置的下基板01和上基板02,位于上基板02与下基板01之间的液晶层03,相互绝缘的像素电极04和公共电极层05,以及多条导线06;其中,公共电极层被分割成多个相互独立的自电容电极051,且自电容电极051与对应的导线06连接;还包括:
与自电容电极051异层且绝缘设置、且至少覆盖部分相邻自电容电极051之间的分割间隙的补偿电极07,补偿电极07用于在显示时间段加载公共电极信号;
自电容电极051、导线06和补偿电极07均设置于上基板02面向下基板01一侧或下基板01面向上基板02一侧,图2a所示为自电容电极、导线和补偿电极均设置于下基板面向上基板一侧的示意图,图2b为自电容电极导线和补偿电极的俯视结构示意图。
本发明实施例提供的上述触摸显示面板,公共电极层被分割成多个相互独立的自电容电极,利用公共电极复用为自电容电极,不需要增加额外的膜层,仅需要将现有液晶显示屏中的公共电极层图形进行变更,节省了生产成本,提高了生产效率。由于上述触摸显示面板中的自电容电极是利用公共电极层分割形成,因此还包括与自电容电极异层且绝缘设置、且至少覆盖部分相邻自电容电极之间的分割间隙的补偿电极,补偿电极用于在显示时间段加载公共电极信号。这样在显示时,利用在补偿电极上加载的公共电极信号可以补偿自电容分割间隙处的公共电极信号,从而保证分割间隙处液晶正常翻转,保证整个显示面板显示正常。并且,在补偿电极上加载的公共电极信号,还可以保证位于补偿电极对应区域的信号线与位于自电容电极下方的同种信号线上的电容一致,从而保证位于触摸显示面板中同种信号线上的信号延迟一致。
本发明实施例提供的上述触摸显示面板,既适用于扭转向列(Twisted Nematic,TN)型液晶显示屏,也适用于高级超维场开关(Adwanced Dimension Switch,ADS)型液晶显示屏、高开口率高级超维场开关(High-Adwanced Dimension Switch,HADS)型液晶显示屏和平面内开关(In-Plane Switch,IPS)型液晶显示屏。
较佳地,在具体实施时,本发明实施例提供的上述触摸显示面板,如图3所示,补偿电极07覆盖全部相邻自电容电极051之间的分割间隙。
较佳地,在具体实施时,考虑到在制作时的尺寸偏差和对位精度,在本发明实施例提供的上述触摸显示面板中,如图3所示,补偿电极07在下基板的正投影为至少覆盖所有分割间隙的网格状结构。即补偿电极07的宽度稍微大于对应位置处分割间隙的宽度。
进一步地,在具体实施时,为了避免补偿电极影响开口率,在本发明实施例提供的上述触摸显示面板中,补偿电极的材料为透明导电材料。
一般地,触摸屏的密度通常在毫米级,因此,在具体实施时,可以根据所需的触控密度选择各自电容电极的密度和所占面积以保证所需的触控密度,通常各自电容电极设计为5mm*5mm左右的方形电极。而显示屏的密度通常在微米级,因此,一般一个自电容电极会对应显示屏中的多个像素。
由于,本发明实施例提供的上述触摸显示面板是将现有的整层设置在的公共电极层分割成多个自电容电极,为了进一步不影响正常的显示功能,在对公共电极层进行分割时,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。
具体地,在具体实施时,在本发明实施例提供的上述触摸显示面板中,还包括:设置于上基板面向下基板的一侧,或设置于下基板面向上基板的一侧的黑矩阵层;
相邻的两个自电容电极之间的分割间隙在下基板的正投影均位于黑矩阵层的图形所在区域内。
较佳地,为了避免自电容电极之间产生触控盲区,在发明实施例提供的上述触摸显示面板中,如图3所示,各导线06与自电容电极051异层设置,且各导线06通过过孔与对应的自电容电极051连接。
具体地,在具体实施时,导线的材料一般金属材料,为了避免金属材料的导线影响显示面板的开口率,在发明实施例提供的上述触摸显示面板中,各导线在下基板的正投影均位于黑矩阵层的图形所在区域内。
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,面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面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。
因此,当本发明实施例提供的上述触摸显示面板应用于HADS型液晶显示屏时,自电容电极位于下基板面向上基板一侧,像素电极位于公共电极层上方,补偿电极与像素电极同层设置。由于像素电极仅设置在与各像素对应的位置,而补偿电极正好位于相邻像素之间,因此可以对现有液晶显示屏中的像素电极层图形进行变更,通过一次构图工艺形成像素电极与补偿电极的图形,不需要增加额外的膜层,节省了生产成本,提高了生产效率。
因此,当本发明实施例提供的上述触摸显示面板应用于ADS型液晶显示屏时,自电容电极位于下基板面向上基板一侧,公共电极位于像素电极上方,补偿电极位于公共电极上方。在制作时需要在形成公共电极之后,在公共电极上依次形成绝缘层和导电层,通过一次构图工艺在导电层中形成补偿电极的图形。因此,上述触摸显示面板应用于ADS型液晶显示屏与应用于HADS型液晶显示屏相比,增加了两层膜层和一次构图工艺。
具体地,由于本发明实施例提供的上述触摸显示面板采用公共电极层复用作为自电容电极,为了减少显示和触控信号之间的相互干扰,在具体实施时,需要采用触控和显示阶段分时驱动的方式,并且,在具体实施时还可以将显示驱动芯片和触控侦测芯片整合为一个芯片,进一步降低生产成本。
因此,在具体实施时,本发明实施例提供的上述触摸显示面板还可以包括:与各导线电连接的触控侦测芯片;其中,
触控侦测芯片用于在显示时间段对各自电容电极和补偿电极加载公共电极信号,在触控时间段通过检测各自电容电极的电容值变化以判断触控位置。
进一步地,在具体实施时,本发明实施例提供的上述触摸显示面板,在显示时间段时,触控侦测芯片对补偿电极加载公共电极信号可以保证自电容电极分割间隙处液晶的正常旋转,在触控时间段,触控侦测芯片不对补偿电极加载信号,以保证补偿电极不会对自电容电极造成噪声影响。当然,在具体实施时,在触控时间段,触控侦测芯片也可以对补偿电极加载公共电极信号,在此不作限定。
具体地,例如:如图4a和图4b所示的驱动时序图中,将触摸显示面板显示每一帧(V-sync)的时间分成显示时间段(Display)和触控时间段(Touch),例如如图4a和图4b所示的驱动时序图中触摸显示面板的显示一帧的时间为16.7ms,选取其中5ms作为触控时间段,其他的11.7ms作为显示时间段,当然也可以根据IC芯片的处理能力适当的调整两者的时长,在此不做具体限定。在显示时间段(Display),对触摸显示面板中的每条栅极信号线Gate1,Gate2……Gaten依次施加栅扫描信号,对数据信号线Data施加灰阶信号,与各自电容电极Cx1……Cxn连接的触控侦测芯片向各自电容电极Cx1……Cxn分别施加公共电极信号,以实现液晶显示功能。在触控时间段(Touch),如图4a所示,与各自电容电极Cx1……Cxn连接的触控侦测芯片向各自电容电极Cx1……Cxn同时施加驱动信号,同时接收各自电容电极Cx1……Cxn的反馈信号;也可以如图4b所示,与各自电容电极Cx1……Cxn连接的触控侦测芯片向各自电容电极Cx1……Cx n依次施加驱动信号,分别接收各自电容电极Cx1……Cxn的反馈信号,在此不做限定,通过对反馈信号的分析判断是否发生触控,以实现触控功能。
进一步地,在发明实施例提供的上述触摸显示面板中,补偿电极为与各自电容电极均存在预设大小的交叠区域的一体结构。将补偿电极设置为一体结构是为了保证可以通过一个信号端接收信号,将补偿电极设置为与各自电容电极均存在预设大小的交叠区域是为了方面后续的自电容电极检测。
众所周知,一个完整的触摸显示屏一般包括触摸显示面板,驱动芯片和印刷电路板,在制备时,触摸显示面板,驱动芯片(包括本发明实施例提供的上述触控侦测芯片)和印刷电路板是分别制作完成后,再将制作好的触摸显示面板与驱动芯片和印刷电路板进行绑定。但是,为了节约成本,在绑定前,一般先要确定触摸显示面板是合格的。因此,在触摸显示面板与驱动芯片在绑定前,需要对触摸显示面板进行各种性能的检测。在检测各自电容电极是否合格时,由于所有自电容电极之间是相互独立的,因此现有技术中,需要针对每个自电容电极再单独设置一个薄膜晶体管(TFT,Thin Film Transistor),各TFT的栅极连接同一开关控制线,各TFT的源极连接同一信号线用于接收公共电极信号,各TFT的漏极分别与对应的自电容电极连接。这样当测试时,向信号线输入公共电极信号,向各像素电极输入测试信号,当向开关控制线输入控制信号时所有TFT导通,此时若所有自电容电极均正常,则整个触摸显示面板正常显示,若有些像素点不能正常显示,则说明该像素点对应位置处的自电容电极存在异常,该触摸显示面板不合格。
从上述可知,在现有技术中,要测试所有自电容电极是否正常,不仅需要针对各自电容电极单独设置TFT,并且还需要设置大量与各TFT连接的线,不仅会增加成本,并且还会占用触摸显示面板大量空间,从而降低触摸显示面板的开口率。
因此,基于同一发明构思,当本发明实施例提供的上述触摸显示面板中的补偿电极为与各自电容电极均存在预设大小的交叠区域的一体结构时,本发明实施例还提供了一种上述触摸显示面板的检测方法,如图5所示,具体可以包括以下步骤:
S501、在触摸显示面板与驱动芯片绑定前,如图6所示,采用激光熔接技术,将位于补偿电极07与各自电容电极051的各交叠区域的补偿电极07与自电容电极051连接;其中,补偿电极07与自电容电极051连接点08如图6所示;
S502、向补偿电极通入公共电极信号,并向像素电极通入测试信号,确定触摸显示面板的所有像素点是否正常显示;若是,则执行步骤S503,若否,则执行步骤S504,
S503、则采用激光切割技术,将各交叠区域补偿电极与自电容电极连接的位置切断,使补偿电极与各自电容电极绝缘,并将触摸显示面板与驱动芯片绑定;
S504、则确认触摸显示面板中有自电容电极存在异常。
本发明实施例提供的上述检测方法,由于补偿电极为与各自电容电极均存在预设大小的交叠区域的一体结构,因此在触摸显示面板与驱动芯片绑定前,可以利用激光熔接技术,将位于补偿电极与各自电容电极的各交叠区域的补偿电极与自电容电极连接,从而使各自电容电极通过补偿电极整体导通,这样向补偿电极通入公共电极信号,就可以实现向所有自电容电极传输公共电极信号的目的,并向像素电极通入测试信号,就可以确定触摸显示面板的所有像素点是否正常显示,若所有的自电容电极上均加载有公共电极信号,触摸显示面板的所有像素点则能正常显示,若有自电容电极上没有加载有公共电极信号,则与该自电容电极对应的液晶则不能正常翻转,从视觉上表现为该处像素点显示异常。因此,可以通过判断整个触摸显示面板中所有像素点的显示,判断触摸显示面板是否合格,如果合格,则采用激光切割技术,将各交叠区域补偿电极与自电容电极连接的位置切断,使补偿电极与各自电容电极绝缘,然后再将触摸显示面板与驱动芯片绑定,避免了由于将不合格的触摸显示面板与驱动芯片绑定所导致的不必要的浪费。
正是由于上述检测方法可以通过补偿电极实现向所有自电容电极施加公共电极信号,因此与现有技术相比可以省去设置检测用TFT以及与各TFT连接的走线的设置,从而可以降低成本和增加开口率。
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触摸显示面板的实施例,重复之处不再赘述。
本发明实施例提供的一种触摸显示面板、其检测方法及显示装置,公共电极层被分割成多个相互独立的自电容电极,利用公共电极复用为自电容电极,不需要增加额外的膜层,仅需要将现有液晶显示屏中的公共电极层图形进行变更,节省了生产成本,提高了生产效率。由于上述触摸显示面板中的自电容电极是利用公共电极层分割形成,因此还包括与自电容电极异层且绝缘设置、且至少覆盖部分相邻自电容电极之间的分割间隙的补偿电极,补偿电极用于在显示时间段加载公共电极信号。这样在显示时,利用在补偿电极上加载的公共电极信号可以补偿自电容分割间隙处的公共电极信号,从而保证分割间隙处液晶正常翻转,保证整个显示面板显示正常。并且,在补偿电极上加载的公共电极信号,还可以保证位于补偿电极对应区域的信号线与位于自电容电极下方的同种信号线上的电容一致,从而保证位于触摸显示面板中同种信号线上的信号延迟一致。
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。
