Description

液晶显示面板 技术领域
本申请涉及显示技术领域,尤其涉及一种液晶显示面板。
背景技术
随着TFT-LCD(Thin Film Transistor-Liquid Crystal Display,薄膜场效应晶体管液晶显示器)的不断发展,人们对于显示器窄边框的要求也越来越高。为了进一步降低显示器边框的宽度,目前业界最普遍的做法是将栅极驱动电路(Gate On Array,简称GOA)制作在TFT基板上。这样既不需要栅极驱动芯片(IC),还可以把边框做到很窄。使用栅极驱动芯片IC的显示器边框一般在5mm以上,而采用GOA驱动的TFT基板的显示器边框一般在3mm以下。目前,小尺寸GOA液晶产品的结构一般是将阵列基板与彩膜基板之间由一层封框胶将其贴合,以防止内部的液晶发生外泄。为了使产品有更好的显示品质及更长的耐信赖性,人们希望封框胶材料可以有好的接着力,在搬送及运输过程中不会发生界面分析而产生气泡,同时有好的阻水性,确保在高温高湿的环境下,水汽不会进入盒内,造成电性不良。然而,现有的封框胶运用到GOA液晶产品时,时钟信号线路的挖孔位置容易在水汽腐蚀下发生水平线不良,因此GOA液晶产品的封框胶涂布位置有限制,需避开液晶产品的时钟信号线路的挖孔位置。
综上所述,现有的液晶显示面板所使用的封框胶构件运用到GOA液晶产品时,在GOA电路中的时钟信号线路的挖孔位置容易在水汽腐蚀下发生水平线不良,从而难以避免GOA电路短路的情况出现,进一步影响了液晶显示面板的显示效果。

具体地,所述液晶显示面板100中所述阵列基板10一侧还设置有隔离柱50,所述隔离柱50分别形成于所述振谐信号线1051上以及所述公共电极线1053上。所述隔离柱50可以由聚酰亚胺材料通过光刻或印刷制成。
具体地,所述液晶显示面板100中彩膜基板20一侧上对应设置有所述栅极驱动GOA电路105的区域设置有第一基板201、黑色矩阵202以及像素电极203,所述封框胶40与所述像素电极203相接触。
由于所述第一子封框胶41材质的粘接力较强,且所述第二子封框胶42的阻水率较强。能够保护所述时钟信号线1032免受外界水汽侵蚀,解决了现有的封框胶材料难以兼顾接着力及阻水性的难点,进而解决GOA液晶产品水汽导致的信赖性不良,实现窄边框产品设计需求,提升产品品质及竞争力。
综上所述,本申请实施例提供的液晶显示面板,在设置有栅极驱动GOA电路的区域,分别覆盖粘接力较强的第一子封框胶与阻水性较强的第二子封框胶,解决了GOA液晶产品因水汽侵蚀导致的信赖性不良问题,进一步实现了窄边框产品的设计需求。
可以理解的是,对本领域普通技术人员来说,可以根据本申请的技术方案及其发明构思加以等同替换或改变,而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
