Description

一种显示基板和显示装置 技术领域
本发明涉及显示技术领域，具体地，涉及显示基板和显示装置。
背景技术
液晶显示(LCD：Liquid Crystal Display)装置因其体积小、功耗低、无辐射等特点已成为目前平板显示装置中的主流产品。液晶显示面板是液晶显示装置中的关键器件，液晶显示面板包括对盒的阵列基板和彩膜基板、以及设置在阵列基板和彩膜基板之间的液晶层。
为了使液晶显示面板中的液晶在未通电时保持特定的取向，在阵列基板和彩膜基板的彼此面对的表面上要形成取向层。取向层表面形成有特定取向的沟槽，沟槽通常通过摩擦布摩擦形成。
在形成阵列基板的取向层的摩擦工艺过程中，常常容易产生摩擦阴影Rubbing Mura(也叫摩擦痕，其是指利用摩擦布摩擦阵列基板的表面而形成取向层中的沟槽的一致性差，即取向层中的沟槽取向的不一致性)，严重影响液晶显示面板的显示品质。
经过试验发现，摩擦阴影并不是由摩擦布本身造成的，而是由阵列基板外围线路的布线设计造成的。在阵列基板的非显示区域通常会布设一些用于测试显示面板显示是否正常或良好的测试电极，测试电极用于将测试信号传入至显示面板内部以进行测试。为了便于测试信号的顺利传入，测试电极通常被设计为面积较大的块状，而测试电极的周边布线通常被设计为较细的线条状，这就导致测试电极和其周边布线存在一定的表面形态差异。
在通过摩擦布进行摩擦取向的过程中，摩擦布通常从阵列基板的一侧边开始摩擦，直至摩擦到阵列基板的相对另一侧边为止，由于块状的测试电极和其周边线条状布线的表面形态存在很大的差异，所以使得摩擦布的布毛取向比较混乱(即取向不一致)，从而导致当摩擦布从非显示区域摩擦进入显示区域时，摩擦形成的沟槽的取向不一致，即很容易产生摩擦阴影，严重影响液晶显示面板的成像质量。

具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明所提供的一种显示基板和显示装置作进一步详细描述。
实施例1：
本实施例提供一种显示基板，如图1所示，包括显示区1和非显示区2，显示区1的表层用于被摩擦以形成取向层，非显示区2设置有测试电极3，测试电极3包括多个条状的第一子电极31，第一子电极31的延伸方向与摩擦形成取向层的摩擦的方向一致。
将测试电极3分割为多个条状的第一子电极31，且第一子电极31的延伸方向(即长度方向)与摩擦形成取向层的摩擦的方向一致。通过这种方式能使摩擦形成的取向层的取向一致且均匀，从而避免摩擦形成取向层时摩擦阴影的出现。
本实施例中，多个第一子电极31的垂直于其延伸方向的宽度相同，且多个第一子电极31等间距设置。如此设置，能使由测试电极3分割成的多个第一子电极31分布均匀，分布均匀的第一子电极31能对用于进行摩擦来形成取向层的摩擦布的布毛进行梳理，使摩擦布 的布毛分布均匀且方向一致，从而使通过摩擦布摩擦形成的取向层也更加均匀且取向一致，进而避免摩擦阴影的出现。
本实施例中，非显示区2还设置有绑定电极4。绑定电极4包括多个条状、等间隔设置且大小相同的第二子电极41，第二子电极41的延伸方向(即长度方向)与摩擦形成取向层的摩擦的方向一致。第一子电极31的宽度与第二子电极41的垂直于其延伸方向的宽度相同，相邻的第一子电极31之间的间距等于相邻的第二子电极41之间的间距。可以将绑定电极4设置到在摩擦方向上不与测试电极3相对应的空白区域中。在设置了间隔物6(后文将描述)的情况下，可以将绑定电极4设置到在摩擦方向上不与测试电极3和间隔物6相对应的空白区域中。具体地，如图1所示，在垂直于摩擦方向的方向(横向)上排列的测试电极3和间隔物6所形成的行中，存在未设置测试电极3或间隔物6的空白区域。可以将绑定电极4设置在与该空白区域相对应的另一行中。
由于绑定电极4和测试电极3均设置在非显示区2，且当摩擦布进行摩擦来形成取向层时，摩擦布会先从显示基板一侧的非显示区2开始向显示区1的方向进行摩擦，因此非显示区2的绑定电极4和测试电极3的上述设置能够在摩擦布的布毛摩擦经过显示区1之前对其进行很好的梳理，使摩擦布的布毛分布均匀且方向一致，这能使摩擦形成的取向层的取向一致且均匀，避免摩擦阴影的出现。
本实施例中，第一子电极31和第二子电极41均位于非显示区2的表层，且第一子电极31和第二子电极41的表面平齐。如此设置，有利于通过第一子电极31和第二子电极41将摩擦布的布毛梳理一致，从而使通过摩擦布进行摩擦形成的取向层的取向更加均匀和一致。因为如果第一子电极31和第二子电极41的表面不平齐，则摩擦布的布毛在经过第一子电极31的表面和第二子电极41的表面时其弯曲程度会明显不同，由此会直接导致通过摩擦布进行摩擦形成的取向层的取向不一致。
本实施例中，如图2所示，第一子电极31包括第一导电层311、绝缘层312和第二导电层313，第一导电层311、绝缘层312和第二 导电层313从下到上依次层叠，绝缘层312还延伸至覆盖任意相邻两个第一子电极31之间的间隔区域。由于第一导电层311、绝缘层312和第二导电层313依次通过传统的构图工艺逐层形成，所以任意相邻两个第一子电极31之间的间隔区域最终形成为条形槽状，该条形槽的深度可以为第一导电层311的厚度和第二导电层313的厚度之和，该深度的条形槽有利于对摩擦布的布毛进行很好梳理，从而使通过摩擦布进行摩擦形成的取向层的取向效果更好。
在绝缘层312的对应第一导电层311和第二导电层313的区域中开设有过孔314，第一导电层311和第二导电层313通过过孔314电连接。第一导电层311与显示基板内部的信号测试线设置在同一层且相互电连接，第二导电层313设置在第一导电层311的正上方，用于将外部测试信号引入至显示基板内部的信号测试线上，过孔314的设置能够实现第一导电层311和第二导电层313之间的电连接。
本实施例中，如图3所示，多个第一子电极31的第一导电层311之间通过第三电极5电连接，并且多个第一子电极31的第二导电层313之间通过第三电极5电连接。其中，将多个第一子电极31的第一导电层311进行电连接的第三电极5与第一导电层311设置在同一层中，将多个第一子电极31的第二导电层313进行电连接的第三电极5与第二导电层313设置在同一层中。第三电极5的设置能使由多个第一子电极31构成的整个测试电极3的截面积增大，从而减小了整个测试电极3的电阻，有利于测试信号的正常输入。
需要说明的是，第三电极5也可以只将多个第一子电极31的第一导电层311连接在一起，或者，只将多个第一子电极31的第二导电层313连接在一起，同样能使整个测试电极3的电阻减小，有利于测试信号的正常输入。
其中，第三电极5为条状且其延伸方向(即长度方向)垂直于第一子电极31的延伸方向。第三电极5的垂直于其延伸方向的宽度设置为较小，以利于保持第一子电极31之间的间隙的长度，从而保证对布毛的梳理效果。优选地，第三电极5的垂直于其延伸方向的宽度小于第一子电极31的宽度。如此设置，既能确保整个测试电极3 的电阻减小，又不会影响多个第一子电极31对摩擦布的布毛的梳理，从而仍然能够确保通过摩擦布进行摩擦形成的取向层的取向一致。
本实施例中，第三电极5位于第一子电极31的沿其延伸方向的端部。即与第一导电层311设置在同一层的第三电极5将第一导电层311的端部连接在一起，与第二导电层313设置在同一层的第三电极5将第二导电层313的端部连接在一起。第三电极5将第一子电极31的端部连接在一起，能够更好地避免第三电极5对摩擦布布毛的梳理的影响(因为第三电极5的延伸方向垂直于摩擦布进行摩擦的方向)。
在其他实施例中，如图4所示，第三电极5也可以位于第一子电极31的沿其延伸方向的中间，即第三电极5在第一子电极31的1/2长度的位置处将第一子电极31连接在一起。由于第三电极5的宽度小于第一子电极31的宽度，所以第三电极5通常不会对摩擦布布毛的梳理产生很大的影响。
本实施例中，如图1所示，测试电极3包括多个，多个测试电极3相互间隔分布，在测试电极3之间的任意一个间隔区域均设置有多个条状且相互间隔的间隔物6，间隔物6的延伸方向与第一子电极31的延伸方向一致。间隔物6的垂直于其延伸方向的宽度等于第一子电极31的宽度，设置在测试电极3之间的同一个间隔区域内的任意相邻两个间隔物6之间的间距相等且等于相邻两个第一子电极31之间的间距。
需要说明的是，间隔物6可以采用导电材料形成，也可以采用绝缘材料形成。采用导电材料形成的间隔物6能与第一子电极31通过一次构图工艺同时形成，无需增加额外的工艺步骤。采用绝缘材料形成的间隔物6可以通过额外增加一次构图工艺形成，也可以与位于第一子电极31下方的其他绝缘层同时形成。
间隔物6的设置使得摩擦布经过测试电极3之间的间隔区域时其布毛能够得到很好的梳理，从而使通过摩擦形成在整个显示区1中的取向层的取向更加一致和均匀。
本实施例中，第一子电极31和与之相邻的间隔物6之间的间距等于相邻两个第一子电极31之间的间距。如此设置，能够确保摩擦 布经过测试电极3和间隔物6时其布毛被梳理均匀且布毛的方向一致，从而确保通过摩擦形成的取向层的取向一致且均匀。
其中，间隔物6位于非显示区2的表层，且间隔物6和第一子电极31的表面平齐。如此设置，能使摩擦布的布毛经过第一子电极31和间隔物6的梳理之后，布毛的弯曲程度和方向都非常一致，从而使通过摩擦布进行摩擦形成的取向层的取向一致。
本实施例中的显示基板为阵列基板或彩膜基板。
实施例2：
本实施例提供一种显示基板，与实施例1不同的是，如图5所示，第三电极5设置有多个。设置在第一子电极31之间的同一个间隙中的多个第三电极5相互间隔。这种设置能够加强第一子电极31的电连接。图5中，第三电极5的总数量略多于第一子电极31的总数量。然而，优选地，第三电极5的总数量小于第一子电极31的总数量，以使得同一间隙中的第三电极5的数量较小，从而确保第三电极5的存在不会影响摩擦取向效果。
本实施例中的显示基板的其他结构与实施例1中的相同，此处不再赘述。
多个第三电极5的设置能使测试电极3的表面积增大，从而有利于测试信号输入到测试电极3上。例如，当对显示基板进行测试时，较大表面积的测试电极3更有利于用于引入测试信号的探针可靠和有效地接触测试电极3。同时，多个第三电极5的设置还能够进一步减小整个测试电极3的电阻，从而有利于测试信号的顺利输入。另外，由于第三电极5的宽度小于第一子电极31的宽度，所以第三电极5通常不会对摩擦布布毛的梳理产生很大的影响。
实施例1-2的有益效果：实施例1-2中所提供的显示基板通过将测试电极分割为多个条状的第一子电极，且第一子电极的延伸方向(即长度方向)与通过摩擦形成取向层的摩擦的方向一致，能使通过摩擦形成的取向层的取向一致且均匀，从而避免通过摩擦形成取向层时摩擦阴影的出现。
实施例3：
本实施例提供一种显示装置，包括实施例1-2的任一个中的显示基板。
通过采用实施例1-2的任一个中的显示基板，使该显示装置在显示时不会出现摩擦阴影，从而提升了该显示装置的显示质量。
本发明所提供的显示装置可以为液晶面板、液晶电视、液晶显示器、手机、导航仪等具有液晶显示功能的任何产品或部件。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
