Description
技术领域
本申请涉及显示技术领域,具体涉及一种阵列基板。
背景技术
液晶显示器应用越来越广泛,其工作原理:液晶是一种介于固体和液体之间的特殊物质,它是一种有机化合物,常态下呈液态,但是它的分子排列却和固体晶体一样非常规则,因此取名液晶,它的另一个特殊性质在于,如果给液晶施加一个电场,会改变它的分子排列,这时如果给它配合偏振光片,它就具有阻止光线通过的作用(在不施加电场时,光线可以顺利透过),如果再配合彩色滤光片,改变加给液晶电压大小,就能改变某一颜色透光量的多少,也可以形象地说改变液晶两端的电压就能改变它的透光度。
而现有技术中,在IPS(In-Plane Switching,平面转换)和FFS边缘场开关技术(Fringe Field Switching简称FFS)类型的液晶显示器件中,采用的是利用水平电场驱动液晶分子等介质偏转从而调控出射光场的强度变化,从而来调节明暗显示。在新型显示器件中,在需要形成水平电场时,也大多采用水平电极的类似FFS和IPS等架构的驱动方式,利用不同电压驱动控制水平电场强弱。在水平电极设计中,由于利用电场控制电极之间介质的偏转,其电场的强弱和均匀性是非常重要的因素。
但是现有技术中,水平电极提供的电场存在不均匀的情况,导致显示质量较差。因此,现有技术具有缺陷,急需改进。
发明内容
本申请提供一种阵列基板,可以解决水平电极提供的电场存在不均匀的情况,导致显示质量较差的技术问题。
本申请实施例提供一种阵列基板,其包括:一基板、设置于所述基板上的正电极和负电极,所述正电极呈首尾相连的封闭环状结构,所述正电极在所述基板上的垂直投影环绕所述负电极在所述基板上的垂直投影设置。
在本申请所述的阵列基板中,所述正电极的外轮廓形状及内轮廓形状与所述负电极的形状相同。
在本申请所述的阵列基板中,所述正电极与所述负电极的同轴设置。
在本申请所述的阵列基板中,所述正电极呈圆环状,所述负电极呈圆形块状。
在本申请所述的阵列基板中,所述正电极的外轮廓及内轮廓均呈正N边形状,所述负电极呈正N边形块状。
在本申请所述的阵列基板中,所述正电极的N条边分别与负电极的N条边一一正对且平行。
在本申请所述的阵列基板中,所述基板的上设置有第一绝缘层,所述正电极以及所述负电极均设置于所述绝缘层上,且位于同一层。
在本申请所述的阵列基板中,所述第一绝缘层的上设置有第二绝缘层,所述负电极设置于所述第一绝缘层与所述第二绝缘层之间,所述正电极设置于所述第二绝缘层的上表面。
在本申请所述的阵列基板中,所述正电极在所述基板上的垂直投影与所述负电极在所述基板上的垂直投影之间距离为4.5um-5.5um。
在本申请所述的阵列基板中,所述正电极在所述基板上的垂直投影与所述负电极在所述基板上的垂直投影之间距离为5.0um。
本申请实施例提供的阵列基板,通过采用将正极设置为封闭环状图形且环绕负极设置的方式,可以提高水平电场的均匀性,进而可以提高显示质量。

具体实施方式
下面详细描述本申请的实施方式,所述实施方式的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的,仅用于解释本申请,而不能理解为对本申请的限制。
在本申请的描述中,需要理解的是,术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本申请和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本申请的限制。此外,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中,“多个”的含义是两个或两个以上,除非另有明确具体的限定。
请参照图1,图1为本申请实施例中的阵列基板的的俯视结构图。如图1所示,该阵列基板,包括:一基板10、设置于所述基板10上的正电极20和负电极30,所述正电极20呈首尾相连的封闭环状结构,所述正电极20在所述基板上的垂直投影环绕所述负电极30在所述基板上的垂直投影。
当然,可以理解地,阵列基板的基板10上肯定还设置有其他金属层、半导体层及绝缘层,从而形成该阵列基板的TFT阵列层以及对应的扫描线及数据线,然而本发明的改进点仅仅在于电极这一块,因此,对于TFT阵列层不做过多描述。
其中,在一些实施例中,正电极20的外轮廓形状及内轮廓形状与所述负电极30的形状相同。例如,可以均为圆形或者均为正多边形。并且,该正电极20与所述负电极30的同轴设置。
在本实施例中,该正电极20呈圆环状,所述负电极30呈圆形块状。其中,在一些实施例中,该正电极20在所述基板10上的垂直投影与所述负电极30在所述基板10上的垂直投影之间距离为4.5um-5.5um。优选地,正电极20在所述基板10上的垂直投影与所述负电极30在所述基板20上的垂直投影之间距离为5.0um。其中,该正电极20和负电极30均可以采用ITO等透明导电金属制成。
请同时参照图2,图2为本申请实施例中的阵列基板的剖视结构图。在本实施例中,该基板10上还设有第一绝缘层40,该正电极20和负电极30均设置于该第一绝缘层40上,二者位于同一层,且正电极20和负电极30采用一次光罩形成。
当然,可以理解地,请参照图3,图3为本申请实施例中的阵列基板的另一剖视结构图。在该实施例中,第一绝缘层40的上设置有第二绝缘层50,所述负电极30设置于所述第一绝缘层40与所述第二绝缘层50之间,所述正电极20设置于所述第二绝缘层50的上表面。其中,该第一绝缘层40以及第五绝缘层50均可以为氮化硅或者二氧化硅沉积形成。需要说明的是,正电极20所在的层与负电极30所在的层可以替换,在此不做限制。
本申请实施例的阵列基板通过将正、负电极分别设计为圆环形和圆形,其所夹区域的电场趋向于均匀和稳定,可以提高显示质量。
在一些实施例中,请参照图4,图4为本申请一些实施例中的阵列基板的另一种俯视结构图。如图4所示,正电极20的外轮廓及内轮廓均呈正N边形状,所述负电极30呈正N边形块状,例如可以为正六边形、正七边形等。该正电极20的N条边分别与负电极30的N条边一一正对且平行。
在本申请实施例中,为了回避正负电极水平电场存在明显的突变区域引起的显示不良问题,该问题不限于LCD显示领域,也可能发生在纳米粒子发光和有机发光领域,采用将正极环绕负极设置的方式,可以提高水平电场的均匀性,可以提高显示质量。
本申请实施例提供的阵列基板,通过采用将正极设置为封闭环状图形且环绕负极设置的方式,可以提高水平电场的均匀性,进而可以提高显示质量。
虽然本申请已以优选实施例揭露如上,但上述优选实施例并非用以限制本申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
