Description

一种显示面板及其显示装置 技术领域
本发明涉及显示技术领域，具体涉及一种显示面板及其显示装置。
 背景技术
显示装置可以把计算机的数据变换成各种文字、数字、符号或直观的图像显示出来，并且可以利用键盘等输入工具把命令或数据输入计算机，借助系统的硬件和软件随时增添、删改、变换显示内容。显示装置根据所用之显示器件分为等离子、液晶、发光二极管和阴极射线管等类型。
LCD （英文全称：Liquid Crystal Display，液晶显示器）。液晶显示器是以液晶材料为基本组件，在两块平行板之间填充液晶材料，通过电压来改变液晶材料内部分子的排在列状况，以达到遮光和透光的目的来显示深浅不一，错落有致的图象，而且只要在两块平板间再加上三元色的滤光层，就可实现显示彩色图象。
目前主流的LCD是TFT-LCD（英文全称：thin film transistor-liquid crystal display，薄膜晶体管液晶显示器），是由原有的液晶显示技术发展扩展而来的。TFT-LCD主动式液晶显示器中，每个子像素具有一个TFT，其栅极(Gate)连接至水平扫描线，漏极(Drain)连接至垂直方向的数据线，源极(Source)则连接至像素电极。在水平扫描线上施加足够的电压，会使得该条水平扫描线上的所有TFT打开，此时该条水平扫描线上的像素电极会与垂直方向上的数据线连通，从而将数据线上的显示信号电压写入像素，通过TFT上的信号与电压改变来控制液晶分子的转动方向，从而达到控制每个像素点偏振光出射与否而达到显示目的。TFT液晶为每个像素都设有一个半导体开关，以此做到完全的单独的控制一个像素点，液晶材料被夹在TFT玻璃层和颜色过滤层之间，通过改变刺激液晶的电压值进而控制液晶分子的转动方向，从而控制每个像素点偏振光出射与否而达到显示目的，控制最后出现的光线强度与色彩。
 技术问题
其中具有触控功能的TFT-LCD可称为in_cell屏幕，没有触控功能的TFT-LCD可称为外挂屏幕。在外挂屏幕中公共电极是由覆盖整个显示区的ITO组成的，在显示区区外围有一圈金属公共走线，ITO与公共走线通过孔相连。公共电极会受到扫描线、数据线、像素电极的耦合，在显示过程中公共电极上的电压是不停变化的，由于ITO的电阻率较大，公共电极距离公共走线近的部分在受到耦合后的电压恢复较快，而显示区中央的公共电极在受到耦合后的电压恢复较慢，这会使显示区公共电压不均匀。当显示区公共电压不均匀时屏幕边缘和屏幕中央的Best Vcom（使屏幕闪烁最小的Vcom）差异较大，导致屏幕周边闪烁。因此需要寻求一种新型的显示面板以解决上述问题。
 技术解决方案
本发明的一个目的是提供一种显示面板及其显示装置，其能够避免显示区公共电压不均匀导致的屏幕边缘和屏幕中央的Best Vcom差异较大，避免出现屏幕周边闪烁现象。
为了解决上述问题，本发明的一个实施方式提供了一种显示面板，定义有显示区和非显示区，其中所述显示区的显示面板包括：基底层、金属层、平坦层以及公共电极层。其中所述金属层设置于所述基底层上；所述平坦层设置于所述金属层上；所述公共电极层设置于所述平坦层上。其中所述金属层包括：数据走线和公共走线。其中所述数据走线相互平行间隔设置；所述公共走线平行设置于所述数据走线的一侧；其中所述公共走线通过过孔连接于所述公共电极层上。
进一步的，其中相邻所述公共走线之间的间距相等。
进一步的，其中相邻所述公共走线之间包括一条数据走线。
进一步的，其中相邻所述公共走线之间包括2条或2条以上数量的数据走线。
进一步的，其中所述数据走线和所述公共走线采用金属材料相同。
进一步的，其中所述显示区的显示面板还包括：绝缘层和像素电极层。其中所述绝缘层设置于所述公共电极层上；所述像素电极层设置于所述绝缘层上。
进一步的，其中所述公共电极层和所述像素电极层的组成材料包括氧化铟锡。
进一步的，其中所述平坦层的组成材料包括有机绝缘材料。
进一步的，其中所述绝缘层的组成材料包括无机绝缘材料。
本发明的另一个实施方式还提供了一种显示装置，其中包括本发明所涉及的显示面板。
 有益效果
本发明涉及一种显示面板及其显示装置，本发明在所述显示区的数据走线的一侧平行设置公共走线，所述公共走线通过过孔连接于所述公共电极层上；以此可以使显示区的公共电压变得均匀，减小屏幕边缘和屏幕中央的Best Vcom差异，改善屏幕周边闪烁现象。
