技术领域
本公开涉及显示技术领域，特别是指一种显示基板母板及其制作方法、显示基板、面板及装置。
背景技术
TFT-LCD(薄膜晶体管-液晶显示器)被广泛应用于多种显示领域中。液晶显示面板一般由彩膜基板、阵列基板以及两基板间填充的液晶组成，为保证液晶显示面板的显示品质，还需要在彩膜基板和阵列基板之间添加柱状隔垫物阵列，使彩膜基板和阵列基板之间保持数μm的距离，从而保证可流动的液晶在液晶显示面板内部均匀分布。
窄边框为目前TFT-LCD的发展趋势。目前MDL(显示模组)段边框逐渐变窄，在不改变显示面板设计的基础上，同时保证MDL强度的基础上，金属边框会逐渐流行。相关技术中的显示基板母板上形成有整层的面状电极，在对显示基板母板进行切割形成显示基板后，切割后的面状电极在显示基板边缘会形成毛刺，在对显示器进行挤压或碰撞后，面状电极的毛刺易与金属边框接触，从而导致面状电极上加载的电压不稳定，造成画面显示异常。
发明内容
本公开要解决的技术问题是提供一种显示基板母板及其制作方法、显示基板、面板及装置，能够使显示装置的面状电极上加载的电压保持稳定，保证显示装置的画面质量。

进一步地，所述阈值为0.1mm。
本公开实施例还提供了一种显示基板母板，包括：
位于显示基板母板上的多个相互独立的面状电极，每一所述面状电极的边缘与平行的所述显示基板母板的预设切割线之间的垂直距离大于阈值。

本公开实施例还提供了一种显示基板，所述显示基板上的面状电极的边缘与所述显示基板的边缘之间的垂直距离大于阈值。
进一步地，所述阈值为0.1mm。
进一步地，所述显示基板为阵列基板，所述面状电极为所述阵列基板上的公共电极；
或所述显示基板为彩膜基板，所述面状电极为所述彩膜基板上的公共电极。

本公开实施例还提供了一种显示装置，包括如上所述的显示面板和用于封框所述显示面板的金属边框。
本公开的实施例具有以下有益效果：
上述方案中，在显示基板母板上形成整层的面状电极层之后，对面状电极层进行构图，去除显示基板母板的预设切割线周边的面状电极层，形成多个相互独立的面状电极，每一面状电极的边缘与平行的预设切割线之间的垂 直距离大于阈值，这样在对显示基板母板进行切割形成显示基板后，显示基板上的面状电极与显示基板的边缘之间的垂直距离大于阈值，这样在显示装置受到挤压或碰撞后，显示装置的金属边框也不会与显示基板的面状电极接触，从而能够使显示装置的面状电极上加载的电压保持稳定，保证显示装置的画面质量。

本实施例中，显示基板上的面状电极的边缘与所述显示基板的边缘之间的垂直距离大于阈值，这样在包括显示基板的显示装置受到挤压或碰撞后，显示装置的金属边框也不会与显示基板的面状电极接触，从而能够使显示装置的面状电极上加载的电压保持稳定，保证显示装置的画面质量。
其中，显示基板可以为彩膜基板或阵列基板，面状电极可以为彩膜基板或阵列基板上的公共电极，对于TN型的显示面板来说，公共电极位于彩膜基板上；对于水平电场型的显示面板来说，公共电极位于阵列基板上。当然，面状电极并不局限为公共电极，还可以为其他类型的电极。
可选地，面状电极的边缘与所述显示基板的边缘之间的垂直距离大于 0.1mm，这样可以使得面状电极的边缘与显示基板的边缘保持足够的距离，避免面状电极与金属边框接触。具体地，所述面状电极的边缘与显示基板的边缘之间的垂直距离可以为0.15mm。
本实施例还提供了一种显示面板，包括如上所述的显示基板以及与所述显示基板对盒设置的对向基板。
本实施例还提供了一种显示装置，包括如上所述的显示面板和用于封框所述显示面板的金属边框。所述显示装置可以为：液晶电视、液晶显示器、数码相框、手机、平板电脑等任何具有显示功能的产品或部件，其中，所述显示装置还包括柔性电路板、印刷电路板和背板。
下面以面状电极为彩膜基板上的公共电极为例，对本公开的技术方案进行详细说明，本公开在制作彩膜基板母板时，增加一次构图工艺，对彩膜基板母板上的公共电极层进行构图，去除彩膜基板母板的预设切割线周边的面状电极层，形成多个相互独立的公共电极，每一公共电极与平行的预设切割线之间间距一定距离，这样对彩膜基板母板进行切割形成彩膜基板后，彩膜基板上的公共电极与彩膜基板的边缘也间距一定距离，能够避免切割后形成毛刺导致公共电极外露。
如图4所示，本实施例的显示面板包括对盒设置的彩膜基板和阵列基板，彩膜基板背向阵列基板的一侧设置有偏光片9，阵列基板背向彩膜基板的一侧设置有偏光片1，彩膜基板包括衬底基板8和设置在衬底基板8上的黑矩阵7和公共电极6，阵列基板包括衬底基板2和位于衬底基板2上的栅金属层3和显示膜层4，彩膜基板和阵列基板通过封框胶5封装在一起，如图5所示，本实施例的显示装置还包括封框显示面板的金属边框11，在金属边框11和衬底基板2之间设置有塑料支撑块10。
由图4和图5可以看出，相比图1和图2中的公共电极6，本实施例的公共电极6的边缘往显示面板内部收缩，公共电极6的边缘与彩膜基板的边缘间隔一定距离，这样可以杜绝金属边框11接触公共电极6，如图6所示，即使对显示器进行挤压或碰撞后，公共电极6也不会与金属边框11接触，从而能够保证在显示装置工作时，公共电极6上加载的电压不会受到影响，使 公共电极上加载的电压保持稳定，保证显示装置的画面质量。
其中，公共电极6的边缘与彩膜基板的边缘之间的距离最好大于0.1mm，这样可以使得公共电极6的边缘与彩膜基板的边缘保持足够的距离，避免公共电极6与金属边框11接触。具体地，公共电极6的边缘与彩膜基板的边缘之间的垂直距离可以为0.15mm，当然，公共电极6的边缘与彩膜基板的边缘之间的垂直距离还可以更大，但同时要保证公共电极6的收缩不会影响显示装置的正常显示，公共电极6缩减后的边缘不能位于封框胶5内侧，公共电极6必须要与封框胶5相接触，否则将影响公共电极6与阵列基板侧的走线通过封框胶5中的导电球进行连通。
