Description

下窄边框显示面板 技术领域
本揭示涉及液晶显示领域,尤其涉及一种下窄边框显示面板。
背景技术
随着全球信息社会的兴起增加了对各种显示装置的需求。因此,对各种平面显示装置的研究和开发投入了很大的努力,如液晶显示装置(Liquid Crystal Display, LCD)、等离子显示装置(Plasma Display Panel, PDP)、场致发光显示装置(Electro Luminescences Display,ELD)以及真空荧光显示装置(Vacuum Fluorescent Display, VFD)等。
在显示装置普及的同时,用户不仅对显示装置所具备的功能种类和性能要求越来越高,而且用户对显示装置的外观上的要求也越来越高,显示装置的轻薄化以及窄边框等条件也越来越多成为用于选择的显示装置的因素。
在影响手机边框众多的因素中,驱动集成电路占据着重要的作用。目前驱动集成电路常用的结构是将驱动集成电路设置在聚酰亚胺基板上,而检测整个显示面板电性的阵列测试 (array test)电路和单元测试(celltest)电路则直接放在驱动集成电路的输入和输出电路中间。随着手机边框逐渐缩窄,驱动集成电路的大小也会逐渐缩减,剩余的空间不足以放置阵列测试电路和单元测试电路。
综上所述,现有显示面板存在没有富余空间放置阵列测试电路和单元测试电路的问题。故,有必要提供一种下窄边框显示面板来改善这一缺陷。
