Description
技术领域
本发明属于显示技术领域,具体涉及一种阵列基板及显示装置。
背景技术
图1示意出现有的阵列基板的周边区域的结构,其包括驱动芯片、信号连接线、用于与柔性线路板绑定的第一焊盘,其中,所述驱动芯片上具有多个第二焊盘,所述信号连接线的第一端覆盖在所述第一焊盘所在位置的上方,且在与第一焊盘对应的位置具有第一通孔,信号连接线的第二端覆盖在第二焊盘所在位置的上方,且在与第二焊盘对应的位置具有第二通孔。
由于驱动芯片上的第二焊盘的面积较小,出于将低阻抗考虑,因此,通常将信号连接线的第二端设计成比第一端细的结构,从而导致在信号连接线的第二端容易产生ESD(静电释放),进而造成信号连接线的第二端烧毁,造成阵列基板不良。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一,提供一种防止ESD烧毁信号连接线第二端的阵列基板及显示装置。
解决本发明技术问题所采用的技术方案是一种阵列基板,其包括驱动芯片、信号连接线,其中,所述信号连接线的第一端覆盖在与***电路板对应的第一焊盘所在位置的上方,且在与所述第一焊盘对应的位置具有第一通孔;所述信号连接线的第二端覆盖在与所述驱动芯片对应的第二焊盘所在位置的上方,且在与所述第二焊盘对应的位置具有第二通孔;其中,所述阵列基板上还设置静电引出单元,所述静电引出单元与所述信号连接线的第二端连接。
优选的是,所述静电引出单元的远离所述信号连接线的一端比所述信号连接线的第一端细。
优选的是,所述静电引出单元的远离所述信号连接线的一端比所述信号连接线的第二端细。
优选的是,所述静电引出单元与所述信号连接线为一体成型结构。
优选的是,所述静电引出单元上设置有多个第三通孔。
优选的是,所述静电引出单元和所述信号连接线的材料为ITO。
优选的是,所述***电路板是柔性线路板。
优选的是,所述静电引出单元形状尖角状。
优选的是,所述驱动芯片为源极驱动芯片和/或栅极驱动芯片。
解决本发明技术问题所采用的技术方案是一种显示装置,其包括上述的阵列基板。
本发明具有如下有益效果:
由于在本发明的阵列基板上增加了与信号连接线第二端连接的静电引出单元,因此可以将阵列基板的生产工艺中所产生的电荷转移到静电引出单元,从而避免在信号连接线的第二端产生ESD而烧毁信号连接线,造成阵列基板不良的问题。
附图说明
图1为现有的阵列基板的周边区域的示意图;
图2为本发明的实施例1的周边区域的示意图。
其中附图标记为:1、信号连接线;11、第一通孔;12、第二通孔;2、第一焊盘;3、驱动芯片;31、第二焊盘;4、静电引出单元。
具体实施方式
为使本领域技术人员更好地理解本发明的技术方案,下面结合附图和具体实施方式对本发明作进一步详细描述。
实施例1:
如图2所示,本实施例提供一种阵列基板,在阵列基板的周边区域设置有驱动芯片3、信号连接线1,其中,所述信号连接线1的第一端覆盖在与***电路板对应的第一焊盘2所在位置的上方,且在与所述第一焊盘2对应的位置具有第一通孔11;所述信号连接线1的第二端覆盖在与所述驱动芯片3对应的所述第二焊盘31所在位置的上方,且在与所述第二焊盘31对应的位置具有第二通孔12;特别的是,本实施例中的阵列基板上还设置静电引出单元4,所述静电引出单元4与所述信号连接线1的第二端连接。
由于现有技术中信号连接线1的第二端比第一端要细,也即信号连接线1与驱动芯片3连接的一端比与第一焊盘2连接的一端要细,因此,造成在阵列基板的生产工艺中所产生的电荷,大部分积累在信号连接线1的第二端上,从而导致在信号连接线1的第二端容易产生ESD(静电释放),进而造成信号连接线1的第二端烧毁。而在本实施例的阵列基板上增加了与信号连接线1第二端连接的静电引出单元4,信号连接线1的第二端和驱动芯片依旧在原焊盘pad的连通位置连接,静电引出单元4不和驱动芯片连接,因此可以将阵列基板的生产工艺中所产生的电荷转移到静电引出单元4,从而避免在信号连接线1的第二端产生ESD而烧毁信号连接线1,造成阵列基板不良的问题。
其中,本实施例中的静电引出单元4与信号连接线1为一体成型结构,且静电引出单元4的远离信号连接线1的一端比所述信号连接线1的第一端细。
之所以如此设置是因为,可以将信号连接线1与静电引出单元4在一次构图工艺中制备,从而可以降低成本,同时可以增加产能。
其中,静电引出单元4的形状可以为尖角状,当然也不局限于该种形状,只要保证静电引出单元4的远离信号连接线1的一端比所述信号连接线1的第一端细即可。
其中,在一个优选实现中,静电引出单元4的远离信号连接线1的一端比所述信号连接线1的第二端细。在该结构下,通过将尖端转移保护关键位置免受损伤。
其中,在所述静电引出单元4上设置有多个第三通孔41。
之所以设置第三通孔41的目的是为了使尖端和与其相连的信号连接线1的第二端的膜层保持一致,确保此静电引出单元4能够将信号连接线1的第二端上的第二通孔12处的静电完全导出。
其中,驱动芯片3包括源极驱动芯片3和/或栅极驱动芯片3。此时,信号连接线1可以将源极驱动芯片3与柔性线路板连接;或者将栅极驱动芯片3与柔性线路板连接;亦或者将栅极驱动芯片3与源极驱动芯片3连接,以及将源极驱动芯片3连接柔性线路板,以使得源极驱动芯片3为栅极驱动芯片3提供高低电平信号。
实施例2:
本实施例提供一种显示装置,其包括实施例1中阵列基板。由于实施例1中的阵列基板上增加了与信号连接线1第二端连接的静电引出单元4,因此可以将阵列基板的生产工艺中所产生的电荷转移到静电引出单元4,从而避免在信号连接线1的第二端产生ESD而烧毁信号连接线1,造成显示装置不良的问题。
该显示装置可以为:手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
当然,本实施例的显示装置中还可以包括其他常规结构,如电源单元、显示驱动单元等。
可以理解的是,以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式,然而本发明并不局限于此。对于本领域内的普通技术人员而言,在不脱离本发明的精神和实质的情况下,可以做出各种变型和改进,这些变型和改进也视为本发明的保护范围。
