Abstract

公开了一种液晶面板（100）及其彩色滤光片基板（20），通过至少一个与水平源极讯号扫描方向垂直的分割线（241），将彩色滤光片基板（20）的一透明导电层（24）分割为多个透明导电层区段（242），其中每一相邻的透明导电层区段（242）彼此之间不相连接。当液晶面板（100）的水平串扰现象发生时，不会影响到相邻的水平区域，因此可降低液晶面板（100）的水平串扰现象，从而提高液晶面板（100）的显示质量。

Description

液晶面板及其彩色滤光片基板 技术领域
本发明涉及液晶面板技术领域，特别是涉及一种可降低水平串扰(H-crosstalk)的液晶面板的彩色滤光片基板。
 背景技术
液晶显示器(Liquid Crystal Display，LCD)是利用液晶材料的特性来显示图像的一种平板显示装置(Flat Panel Display，FPD)，其相较于其他显示装置而言更具轻薄、低驱动电压及低功耗等优点，已经成为整个消费市场上的主流产品。
现今液晶显示器的制作过程中，大致可分为前段矩阵(Array)工艺、中段成盒(Cell)工艺及后段模块化(Module)工艺。前段的矩阵工艺为生产薄膜式晶体管(TFT)基板及彩色滤光片(Color Film)基板。中段成盒工艺则负责将TFT基板与CF基板组合，并两者之间注入液晶与切割合乎产品尺寸之面板。后段模块化工艺则负责将组合后的面板与背光模块、面板驱动电路、外框等做组装的工艺。
液晶显示器所以能呈现彩色的影像，主要就是靠着彩色滤光片所产生的功能：当液晶显示器的背光源透过液晶及驱动IC的控制形成灰阶光源，彩色滤光片上因涂布着红、绿、蓝三色颜料光阻，此光源再通过彩色滤光片即形成红、绿、蓝色光，最后混合形成彩色影像。因此，彩色滤光片是液晶显示器的关键组件，而彩色滤光片的基本结构是由玻璃基板（Glass Substrate）、黑色矩阵层（Black Matrix）、彩色画素层（Color Layer）及透明导电层(ITO, indium tin oxide铟锡氧化物)等所组成。
再者，LCD驱动芯片为液晶显示器的重要零组件，其主要功能是输出需要的电压至像素，以控制液晶分子的扭转程度。LCD驱动芯片分为两种：一为列于X轴的源极驱动芯片(Source Driver IC)与列于Y轴的闸极驱动芯片(Gate Driver IC)。换言之Source驱动芯片是管信号的，Gate驱动芯片则是管门闸的，对于液晶显示面板各有不同的作用。简单来说，LCD的影像是一条线一条线扫瞄下来的Gate驱动芯片是管垂直的信号，假设从最上面的一条线开始，那么就是Gate驱动芯片的第一支脚设为开，其余为关。Source驱动芯片里头是真正的信号(水平的)，它送出的信号只有第一条线的水平像素可以接受。第一条线送完信号，就换第二条线。这时Source驱动芯片的内容要换成第二线的了，然后Gate驱动芯片换成第二支脚开，其余为关，就可以把资料送到第二线。
在现有技术中，由于彩色滤光片基板的公共电极(COM)的电位容易受高低电位影响而耦合，从而产生了水平串扰(H-crosstalk)现象。请参照图1A及图1B所示，图1A揭示一种现有的液晶面板的正常画面示意图；图1B揭示一种现有的液晶面板的产生水平串扰现象时的画面示意图。
如图1A所示，当一画面中A区(例如一低亮度的矩型体)与B区(A区以外的暗色区域)的亮度差异不大时，所述液晶面板能显示出正常的画面。
如图1B所示，当一画面中A(例如一高亮度的矩型体)区与B区(A区以外的暗色区域)的亮度差异增加到某一程度时，与A区水平相邻的B区的彩色滤光片基板COM电位被A区的高电位通过彩色滤光片的透明导电层(ITO)耦合后，就会出现H-crosstalk现象，使与A区水平相邻的B区暗色区域变亮，因而影响所述液晶面板的显示质量。
在现有的液晶面板的的技术领域中，大多是通过电路设计的方式来减少H-crosstalk的影响程度，然而由于H-crosstalk现象本身就是基于电路相互耦合作用所产生的，因此通过电路设计来改善此H-crosstalk现象的效果有限。
故，有必要提供一种液晶面板及其彩色滤光片基板，以解决现有技术所存在的问题。

 本发明的最佳实施方式
为让本发明上述目的、特征及优点更明显易懂，下文特举本发明较佳实施例，并配合附图，作详细说明如下。再者，本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。另外，本发明的各附图是以简化示意的方式来呈现，并且也省略了与说明无关的细节。
请参照图2所示，图2揭示本发明第一实施例的液晶面板的局部剖面示意图。如图2所示，本发明第一实施例的一种液晶面板100主要包含一阵列(TFT)基板10及一彩色滤光片(CF)基板20。所述阵列基板10表面设有多个排列呈矩阵状的薄膜式晶体管11。另外，所述彩色滤光片基板20包含一玻璃基板21、一黑色矩阵层22及一彩色画素层23。其中，所述黑色矩阵层22设于所述玻璃基板21上，并形成多个矩阵状的空隙(未标示)；所述彩色画素层23设于所述玻璃基板21上，其至少包含第一、第二及第三色阻单元(未标示，例如为红、蓝、绿等光的三原色的色阻单元)，其分别位于所述黑色矩阵层的对应空隙内。
如图2所示，所述液晶面板100的彩色滤光片基板20的内表面(图中彩色滤光片基板20的下表面)另设有一透明导电层24，所述透明导电层24覆盖所述黑色矩阵层22及所述彩色画素层23。其中，所述阵列基板10的多个薄膜式晶体管11对应于所述彩色滤光片基板20的黑色矩阵层22；所述阵列基板10的内表面(图中所述阵列基板10的上表面)另设有多个阵列基板的透明导电层12，所述透明导电层12分别对应于所述彩色滤光片基板20的彩色画素层23；所述阵列基板10与所述彩色滤光片基板20通过多个间隙子(未绘示)保持一固定的间隔距离D用以填充液晶(未绘示)，并且所述阵列基板的透明导电层12与所述彩色滤光片基板的透明导电层24没有电性连接。
请参照图3所示，图3揭示本发明第一实施例的液晶面板的构造示意图。所述透明导电层24是设于所述液晶面板100的彩色滤光片基板20的内表面，并覆盖所述黑色矩阵层22及所述彩色画素层23。其中所述透明导电层24包含至少一个与水平源极讯号扫描方向X垂直的分割线241，所述分割线241将所述透明导电层24分割为两个透明导电层区段242，其中每一相邻的所述透明导电层区段242彼此之间不相连接。
因此，当图3画面中A区(例如一高亮度的矩型体)与B区(A区以外的暗色区域)的亮度差异增加到某一程度时，B处的彩色滤光片基板20的公共电极(COM)电位被A处的高电位通过所述透明导电层24耦合后，就会出现水平串扰(H-crosstalk)现象。然而此时，由于所述透明导电层区段242并不相连，因此左边透明导电层区段242的B区的水平串扰现象不会影响到右边的透明导电层区段242，因此某种程度上，降低了所述液晶面板100的水平串扰现象的程度。
本案的所述透明导电层24优选是一ITO层(indium tin oxide铟锡氧化物)，所述透明导电层24的所述分割线241可通过激光等手段形成，但本发明并不限于此。
另外，所述分割线241之间优选地为等距划分，也就是将所述透明导电层24划分为均等宽度的所述透明导电层区段242；且所述分割线241优选地设于所述黑色矩阵层22之上方以避免影响所述彩色画素层23；以及每一所述透明导电层区段242的上下两端优选地分别设有至少一导通用的过孔(VIA孔)243，以提供每一所述透明导电层区段242单独的电性连接需求。
请参照图4所示，图4揭示本发明第二实施例的液晶面板的构造示意图。本发明第二实施例的液晶面板100a大致相似于本发明第一实施例的100，因此沿用相同的组件符号与名称，但其不同之处在于：在本实施例中，所述分割线241a数量为7个，可将所述透明导电层24a分割为八个透明导电层区段242a，其中每一所述透明导电层区段242a彼此之间不相连接。因此当液晶面板100a的水平串扰现象发生时，由于相邻的所述透明导电层区段242a并不相连，使得B区的水平串扰现象不会影响到相邻的水平区域，因此提高所述液晶面板100a的显示质量。
请参照图5所示，图5揭示本发明第三实施例的液晶面板的构造示意图。本发明第三实施例的液晶面板100b大致相似于本发明第一实施例的100，因此沿用相同的组件符号与名称，但其不同之处在于：在本实施例中，所述多个分割线241b将所述透明导电层24b分割为十六个透明导电层区段242b，其中每一相邻的所述透明导电层区段242b彼此之间不相连接。因此当液晶面板100b的水平串扰现象发生时，由于相邻的所述透明导电层区段242b并不相连，使得B区的水平串扰现象不会影响到相邻的水平区域。并且，由于所述透明导电层24b被分割成更多的所述透明导电层区段242b，因此可大幅度地降低了所述液晶面板100b的水平串扰现象，从而显著地提高所述液晶面板100b的显示质量。
因此，本发明并不具体限制所述透明导电层24b的所述分割线241或所述透明导电层区段242的数量。但是可以理解的是，被细分越多的所述透明导电层24可以具有更好的减少水平串扰现象的能力。
相较于现有的液晶面板的的技术领域中，大多是通过电路设计的方式来减少水平串扰(H-crosstalk)现象的影响程度，然而由于H-crosstalk象本身就是基于电路相互耦合作用所产生的现象，因此若通过电路设计来改善此H-crosstalk现象的效果有限。在本发明中，通过改变一液晶面板100的彩色滤光片基板20的构造来改善H-crosstalk现象，也就是通过至少一个与水平源极讯号扫描方向X垂直的分割线241，将所述彩色滤光片基板20的一透明导电层24分割为多个透明导电层区段242，其中每一相邻的所述透明导电层区段242彼此之间不相连接。当H-crosstalk现象发生时，不会影响到相邻的水平区域，因此可降低所述液晶面板100的水平串扰现象，从而提高所述液晶面板100的显示质量。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
