使用该种方式进行液晶配向时,需要在阵列基板上增加大量走线,以给彩膜基板的电极结构提供电压,如图1所示,为所述配向引线与各条信号引线的连接关系,布线1,3,5,7,9表示信号引线,布线2,4,6,8,10表示配向引线,在液晶显示面板进行液晶配向时,通过配向引线输入不同的电压信号,由于不同的电压信号之间存在一定的电压差,如信号引线1连接彩膜基板上的公共电极,信号引线3连接阵列基板的公共电极线(或像素电极),配向引线2输入高电平电压信号给所述信号引线1,而配向线4输入低电平电压信号给所述信号引线3,随着信号传输过程中电荷的累积或施加电压信号时造成的瞬间高压,将导致在传输不同电压信号的走线的跨线处即配向引线2和信号引线3之间¬(如图1虚线框所示)发生静电释放(ESD),静电释放会击穿跨线处的绝缘层,形成短路,在应用于未切割的液晶显示面板时,所述液晶显示面板内包括若干显示单元,未切割液晶显示面板上彩膜基板侧的公共电极100是连接在一起的,阵列基板200上引线发生短路后会拉低对应所述显示单元的彩膜基板公共电极100(如图2所示),进而导致在所述液晶显示面板HVA配向出现异常,造成全区域其他显示单元对应的液晶显示面板报废,降低生产良率。
