Description

包括薄膜晶体管的基板和具有该基板的显示面板
本申请要求2015年7月29日提交的韩国专利申请No.10-2015-0106991的优先权,在此援引该专利申请作为参考,如同在这里完全阐述一样。
技术领域
本发明涉及一种包括薄膜晶体管的基板和具有该基板的显示面板,尤其涉及一种可防止光泄漏而不减小开口率的包括薄膜晶体管的基板和具有该基板的显示面板。
背景技术
在屏幕上显示各种信息的图像显示器是信息通讯时代的核心技术并且正发展成获得更薄、更轻、更便携和更好操作的产品。因此,可克服阴极射线管(CRT)的重量和体积的缺点的平板显示器成为焦点。
在平板显示器之中,液晶显示器通过经由电场调整液晶的光透射率来显示图像,电场形成在公共电极与连接至薄膜晶体管的像素电极之间。液晶显示器形成为:包括滤色器的基板和包括薄膜晶体管的基板彼此结合且在它们之间插入液晶层。此时,为了保持单元间隙(cell gap),在薄膜晶体管基板与滤色器基板之间形成柱状衬垫料。
当从液晶显示器外部施加压力时,柱状衬垫料由于压力而移动。柱状衬垫料的移动导致对与柱状衬垫料接触的取向膜的损坏。因为被损坏的取向膜不能在期望的方向上排列液晶,所以在取向膜的损坏区域中发生光泄漏,这成为问题。特别是,当在厚度上减小基板以获得更薄的液晶显示器时,具有减小的厚度的基板容易通过甚至很小的压力变形,由此薄液晶显示器的光泄漏在一定程度上增加。尽管为了解决这种光泄漏问题可增大柱状衬垫料周围的黑矩阵,但这会降低开口率。
发明内容
因此,本发明旨在提供一种基本上避免了由于相关技术的限制和缺点而导致的一个或多个问题的包括薄膜晶体管的基板和具有该基板的显示面板。
本发明的一个目的是提供一种可防止光泄漏而不减小开口率的包括薄膜晶体管的基板和具有该基板的显示面板。
在下面的描述中将部分列出本发明的附加优点、目的和特征,这些优点、目的和特征的一部分根据下面的解释对于所属领域普通技术人员将变得显而易见或者可通过本发明的实施领会到。通过说明书、权利要求书以及附图中具体指出的结构可实现和获得本发明的这些目的和其他优点。
为了实现这些目的和其他优点并根据本发明的意图,如在此具体化和概括描述的,在根据本发明一个方面的显示面板中,多个阻止层彼此分隔开并且在多个阻止层之间插入有空间,所述多个阻止层设置在与触摸感测线相同的平面上,并且柱状衬垫料设置成与阻止层之间的空间交叠。
根据本发明的一个或多个实施方式,提供一种显示面板,该显示面板包括:公共电极,所述公共电极设置在下基板上并用于接收用户触摸信号;触摸感测线,所述触摸感测线连接至所述公共电极;多个第一阻止层,所述多个第一阻止层设置在与所述触摸感测线相同的平面上并且所述多个第一阻止层之间具有空间从而彼此间隔开;和柱状衬垫料,所述柱状衬垫料设置在与所述下基板相对的上基板上并且与所述第一阻止层之间的空间交叠。
根据本发明的一个或多个实施方式,提供一种薄膜晶体管基板,所述薄膜晶体管基板与包括滤色器的基板相对设置且在它们之间插入柱状衬垫料,所述薄膜晶体管基板包括:多个第一阻止层,所述多个第一阻止层之间具有空间从而彼此间隔开,所述空间设置在与所述柱状衬垫料交叠的区域中;触摸感测线,所述触摸感测线设置在与所述第一阻止层相同的平面上;和公共电极,所述公共电极连接至所述触摸感测线以用于接收用户触摸信号。
应当理解,本发明前面的大体性描述和下面的详细描述都是例示性的和解释性的,意在对要求保护的本发明提供进一步的解释。

图3是图解图2中所示的具有触摸感测线、阻止层和柱状衬垫料的显示面板的剖面图;

图5是图解根据本发明第二实施方式的集成触摸式显示面板的平面图。
具体实施方式
下文中,将参照附图详细描述本发明的实施方式。
图1是图解根据本发明的集成触摸式显示器的框图。
图1中所示的触摸显示器包括数据驱动器194、栅极驱动器192、触摸驱动器196和显示面板。
数据驱动器194响应于来自时序控制器(未示出)的数据控制信号将来自时序控制器的数字数据转换为模拟数据电压,并将模拟数据电压提供至数据线DL。
栅极驱动器192响应于来自时序控制器的栅极控制信号按顺序驱动显示面板的栅极线GL。栅极驱动器192在每条栅极线GL的每一相应扫描时段提供栅极导通电压的扫描脉冲,并且在其他栅极线GL被驱动的其余时段提供栅极截止电压。栅极驱动器192与每个像素的薄膜晶体管(TFT)的制造同时地形成在下基板101的一侧或两侧上的非显示区域中。
触摸驱动器196连接至显示面板的触摸感测线160并且从触摸感测线160接收用户触摸信号。触摸驱动器196通过感测由用户触摸引起的电容变化来检测是否输入了用户触摸以及触摸位置。
显示面板使用布置成矩阵形式的多个像素显示图像。当使用液晶面板作为显示面板时,显示面板包括:包括滤色器的基板170、包括薄膜晶体管的基板190、以及位于基板170和190之间的液晶层180,如图2和3中所示。
包括滤色器的基板170包括按顺序形成在上基板171的下表面上的黑矩阵172、滤色器174、涂覆层176、上取向膜178、第一柱状衬垫料182和第二柱状衬垫料184。
黑矩阵172用于彼此划分红色子像素区域、绿色子像素区域和蓝色子像素区域并防止相邻子像素区域之间的光干涉。黑矩阵172在上基板171的下表面上形成为与栅极线GL、栅极线DL、触摸感测线160和薄膜晶体管TFT的至少之一交叠。
在相应颜色的子像素区域中在上基板171下形成有红色(R)滤色器、绿色(G)滤色器和蓝色(B)滤色器174,以产生相应颜色。
涂覆层176使用透明有机绝缘材料形成在滤色器174和黑矩阵172下方。涂覆层176补偿滤色器174与黑矩阵172之间的高度差。
第一柱状衬垫料182被用作用于保持薄膜晶体管基板190与滤色器基板170之间的单元间隙的间隙衬垫料。为此,第一柱状衬垫料182形成为与单元间隙相同的高度以与下取向膜188接触,并且第一柱状衬垫料182具有比第二柱状衬垫料184大的面积。如此,与第一柱状衬垫料182对应的黑矩阵172的区域大于与第二柱状衬垫料184对应的黑矩阵172的区域。
第二柱状衬垫料184形成为比第一柱状衬垫料182低的高度,第二柱状衬垫料184被用作推压衬垫料(push spacer),其不与下取向膜188接触。第二柱状衬垫料184被用作在引入液晶时可被平稳地填充液晶并且当给上基板171施加压力时可使上基板171易于返回初始状态的通路(passage)。为此,第二柱状衬垫料184具有比第一柱状衬垫料182高的密度。
薄膜晶体管基板190包括连接至彼此交叉以限定像素区域的栅极线GL和数据线DL的薄膜晶体管TFT、像素电极122、公共电极136、触摸感测线160和阻止层(stopper layer)150。
薄膜晶体管TFT响应于栅极线GL的扫描信号利用数据线DL的数据信号将像素电极122充电,并且保持充有数据信号的电压的像素电极122。为此,薄膜晶体管TFT包括栅极电极106、源极电极108、漏极电极110和有源层114,如图3中所示。
栅极电极106与有源层114的沟道区域交叠且在二者之间插入栅极绝缘膜112。
源极电极108经由贯穿层间绝缘膜116的源极接触孔CHs连接至有源层114的源极区域。
漏极电极110面对源极电极108,并且漏极电极110经由贯穿层间绝缘膜116的漏极接触孔CHd连接至有源层114的漏极区域。此外,漏极电极110经由像素接触孔CHp连接至像素电极122。
有源层114在源极电极108与漏极电极110之间形成沟道。有源层114包括沟道区域、源极区域和漏极区域。沟道区域与栅极电极106交叠且在二者之间插入栅极绝缘膜112。n型或p型掺杂剂被引入到源极区域和漏极区域。
上述的薄膜晶体管被由SiNx或SiOx形成的第一保护膜118保护。
像素电极122在由彼此交叉的栅极线GL和数据线DL限定的每个像素区域中形成在第三保护膜138上,像素电极122具有多个狭缝122S。像素电极122电连接至经由像素接触孔CHp暴露的漏极电极110。
公共电极136形成在第二保护膜128上并且在与像素接触孔CHp交叠的区域中具有开口134,开口134具有比像素接触孔CHp大的面积。在每个像素区域中公共电极136与像素电极122交叠且在二者之间插入第三保护膜138。如此,在显示图像的时段被提供公共电压的公共电极136与被提供像素电压信号的像素电极122一起形成边缘电场。布置在薄膜晶体管基板与滤色器基板之间的液晶分子由于介电各向异性而通过边缘电场旋转。此外,经过像素区域的光的透射率根据液晶分子的旋转程度而变化,由此实现灰度。
此外,公共电极136在触摸感测时段,即不显示图像的非显示时段充当感测用户触摸位置的感测电极。为此,以块为单位的多个公共电极136在下基板101上彼此间隔开预定距离,如图1中所示。考虑到用户触摸的面积,每个公共电极136具有与至少一个像素区域对应的尺寸。公共电极136经由触摸接触孔CHt电连接至触摸感测线160。在此,触摸感测线160将由公共电极136感测的用户触摸信号传送至触摸驱动器196。如此,当用户触摸显示面板时,在公共电极136之间产生触摸电容。通过将响应于用户触摸的触摸电容与参考电容进行比较检测用户触摸的位置,并且执行取决于检测到的触摸位置的操作。
同时,每条触摸感测线160设置于每一单位像素上,每一单位像素包括红色(R)子像素、绿色(G)子像素和蓝色(B)子像素。每条触摸感测线160形成为与红色(R)子像素、绿色(G)子像素和蓝色(B)子像素之中的至少一个子像素的数据线DL交叠。
与触摸感测线160并行布置的阻止层150形成在第一柱状衬垫料182和第二柱状衬垫料184每一个的任一侧。就是说,阻止层150形成为与两个其余子像素之中的任意一个子像素的数据线DL(不包括与触摸感测线160交叠的子像素的数据线DL)交叠。例如,触摸感测线160与绿色(G)子像素的数据线DL(即,位于红色(R)子像素和蓝色(B)子像素之间的数据线DL)交叠并且还与设置在红色(R)滤色器和绿色(G)滤色器174之间的黑矩阵172交叠。此外,阻止层150与红色(R)子像素的数据线DL(即,位于蓝色(B)子像素和绿色(G)子像素之间的数据线DL)交叠并且还与设置在红色(R)滤色器和蓝色(B)滤色器174之间的黑矩阵172交叠。
阻止层150使用与触摸感测线160相同材料的金属,比如Al、Cu、Cr、Mo或Ti,与触摸感测线160处于同一平面地形成在平坦化层120上。因此,阻止层150可与触摸感测线160同时形成而不需要额外的掩模工艺,这可降低制造成本。
此外,每个阻止层150形成为与相邻的阻止层150彼此间隔开并且在二者之间插入空间152,空间152与第一柱状衬垫料182和第二柱状衬垫料184的每一个交叠。就是说,在与栅极线GL和数据线DL的交叉部分交叠的黑矩阵172的区域中,一个阻止层150与相邻的阻止层150彼此间隔开第一距离。如此,设置在阻止层150上的第二保护膜128和第三保护膜138的各个上表面在与空间152对应的区域中凹陷,使得在形成于第三保护膜138上的下取向膜188中形成凹部188a。就是说,与空间152对应的下取向膜188的上表面比设置在阻止层150上的下取向膜188的上表面更靠近平坦化层120的上表面。
第一柱状衬垫料182和第二柱状衬垫料184的每一个插入与相邻阻止层150之间的空间152对应的下取向膜188的凹部188a中。在此情形中,当在与数据线DL的纵向方向平行的垂直方向上施加外部压力时,如图4中所示,由于压力,第一柱状衬垫料182或第二柱状衬垫料184的移动被限制在与黑矩阵172交叠的凹部188a内。因此,可防止对设置在像素区域中的下取向膜188的损坏。同时,即使第一柱状衬垫料182或第二柱状衬垫料184响应于相对较强的外部压力而移出凹部188a,第一柱状衬垫料182和第二柱状衬垫料184的每一个沿与黑矩阵172交叠的阻止层150滑动。如此,可使第一柱状衬垫料182和第二柱状衬垫料184从像素区域到下取向膜188的移动最小化。第一柱状衬垫料182和第二柱状衬垫料184与设置在像素区域中的下取向膜188之间的接触可被最小化,这可使对设置在像素区域中的下取向膜188的损坏最小化。
图5是图解根据本发明第二实施方式的显示面板的平面图。
图5中所示的显示面板包括与本发明第一实施方式相同的组件,不同之处在于其进一步包括第二阻止层154,因此下面将省略与相同组件有关的详细描述。
第二阻止层154形成为与设置在触摸感测线160与第一阻止层150之间的黑矩阵172交叠。例如,触摸感测线160与设置在红色(R)滤色器和绿色(G)滤色器174之间的黑矩阵172交叠并且还与和黑矩阵172交叠的绿色(G)子像素的数据线DL交叠。第一阻止层150与设置在蓝色(B)滤色器和红色(R)滤色器174之间的黑矩阵172交叠并且还与和黑矩阵172交叠的红色(R)子像素的数据线DL交叠。第二阻止层154与设置在绿色(G)滤色器和蓝色(B)滤色器174之间的黑矩阵172交叠并且还与和黑矩阵172交叠的蓝色(B)子像素的数据线DL(即位于红色(R)子像素和绿色(G)子像素之间的数据线DL)交叠。第二阻止层154可与不与触摸感测线160交叠的数据线DL交叠。
第一阻止层150和第二阻止层154使用与触摸感测线160相同材料的金属,比如Al、Cu、Cr、Mo或Ti,与触摸感测线160处于同一平面地形成在平坦化层120上。因此,第一阻止层150和第二阻止层154可与触摸感测线160同时形成而不需要额外的掩模工艺,这可降低制造成本。
此外,在与栅极线GL和数据线DL的交叉部分交叠的黑矩阵172的区域中,每个第一阻止层150与相邻的第一阻止层150彼此间隔开并且在二者之间插入第一空间,第一空间具有第一距离d1。在与栅极线GL和数据线DL的交叉部分交叠的黑矩阵172的区域中,每个第二阻止层154与相邻的第二阻止层154彼此间隔开并且在二者之间插入第二空间,第二空间具有小于第一距离d1的第二距离d2。如此,第二阻止层154面对第一柱状衬垫料182和第二柱状衬垫料184的每一个的左侧,触摸感测线160面对第一柱状衬垫料182和第二柱状衬垫料184的每一个的右侧,并且第一阻止层150面对第一柱状衬垫料182和第二柱状衬垫料184的每一个的上侧和下侧。即使在从左下侧到右上侧的对角线方向或在从左上侧到右下侧的对角线方向上施加外部压力,第二阻止层154和触摸感测线160仍可限制第一柱状衬垫料182和第二柱状衬垫料184的移动。此外,即使在垂直方向上施加外部压力,第一阻止层150仍可限制第一柱状衬垫料182和第二柱状衬垫料184的移动。如此,可防止第一柱状衬垫料182和第二柱状衬垫料184移动到显示区域中的下取向膜188,因此可防止对设置在像素区域中的下取向膜188的损坏。
能够理解到,如表1中所示,一直到范围从大约0.47Kgf到0.6Kgf的外部压力为止,根据本发明第一和第二实施方式的液晶显示面板未表现出第一柱状衬垫料182和第二柱状衬垫料184的移动,而当施加大约0.4Kgf的外部压力时,相关技术的液晶显示面板表现出由第一柱状衬垫料和第二柱状衬垫料的移动引起的光泄漏。
表1
相关技术 第一实施方式 第二实施方式
平均产生压力(Kgf) 0.4 0.47 0.6
同时,将根据本发明的薄膜晶体管基板设置成与滤色器基板相对且在二者之间插入液晶层,由此完成了液晶显示面板。此时,尽管在本发明中通过示例的方式描述了边缘电场结构,但水平电场型结构或垂直电场型结构也可适用于所有液晶显示面板。
从上面的描述很显然,根据本发明,与触摸感测线形成在同一平面上的多个阻止层之间具有空间从而彼此间隔开,并且柱状衬垫料设置成与该空间交叠。根据本发明的柱状衬垫料插入到与该空间对应的取向膜的凹部中。如此,即使施加外部压力,柱状衬垫料的移动仍被限制在与黑矩阵交叠的凹部中,这可防止对取向膜的损坏。由此,可防止光泄漏而不减小开口率。此外,即使因为外部压力很强而使得柱状衬垫料移出凹部,柱状衬垫料仍在阻止层上滑动,这可使设置在像素区域中的柱状衬垫料向取向膜的移动最小化。此外,因为阻止层由与触摸感测线相同的材料形成并且与触摸感测线的形成同时形成,所以不需要额外的掩模工艺并且不需要半色调掩模,这可防止制造成本增加。
给出上面的描述仅是通过示例的方式描述本发明,所属领域技术人员能够设计落入本发明的精神和范围内的大量变形例和实施方式。因此,本发明说明书中公开的实施方式不旨在限制本发明。本发明的范围应当通过随后的权利要求书进行解释,本发明的所有技术是要涵盖落入由权利要求书限定的本发明的精神和范围内的所有变形、等同物和替代物。
