 背景技术
随着全面屏的发展，为了提高屏占比，需要减小显示屏的下边界的宽度，如图1所示，现有玻璃衬底芯片 (chip on glass，COG)模组包括衬底基板10、显示区域11、位于显示区域11下方的驱动芯片20以及柔性电路板（FPC）30；其中下边框的尺寸由FPC绑定区的宽度a、柔性电路板至FPC之间的宽度（WOA区宽度）b、驱动芯片20的宽度c、数据线的扇出线的宽度d组成。
然而，这种显示面板结构的边框尺寸比较大，随后出现了图2所示的结构。图2中的显示面板的下边框尺寸主要由数据线的扇出线的宽度d和驱动芯片20的宽度c组成，结合图3，柔性电路板30的输出端子31通过连接线32与驱动芯片20的引脚21连接。

驱动芯片20与所述显示区域11电性连接。比如驱动芯片20与显示区域11的数据线连接。驱动芯片20包括多个引脚21。
如图4和5所示，本发明的柔性电路板30用于连接所述驱动芯片20和电路板，柔性电路板30包括：多个输出端子31，所述输出端子31与所述连接线32对应。引脚21与输出端子31对应。
结合图5，所述输出端子31通过多条连接线32与所述驱动芯片20连接。比如A区域中的输出端子31通过六条连接线32与驱动芯片20连接。
如图5所示，静电保护模块40与所述连接线32连接，静电保护模块40用于当所述连接线32上的实际电压的绝对值大于预设电压时，对所述连接线32上的电流值进行调整，以防止损坏所述连接线32。其中，所述静电保护模块40与靠近所述输出端子31侧的连接线32连接。也即在靠近所述输出端子31侧的连接线32上连接静电保护模块40，以及时对连接线32上的电流进行调整，防止连接线发生静电击穿现象，从而更好地对连接线进行保护。其中所述静电保护模块40位于所述绑定区域的边缘，且位于所述柔性电路板30的外侧。
在一实施方式中，为了更好地防止连接线发生静电击穿现象，如图6所示，所述静电保护模块40包括六个调整单元41，所述调整单元41与所述连接线32对应。在一实施方式中，比如全部连接线32均与所述静电保护模块40连接，每条连接线32对应一调整单元41。也即每条连接线32连接一调整单元41。可以理解的，调整单元41的数量不限。在另一实施方式中，为了简化制程工艺，如图7所示，部分连接线32与所述静电保护模块40连接，比如外侧的3条连接线与所述静电保护模块40连接。其中多条所述连接线32的长度各不相同，越靠近外侧的连接线的长度越大。一实施方式中，设定连接线32与所述静电保护模块40连接，其中每条设定连接线对应一调整单元。所述设定连接线的长度大于预设长度，比如图7中最外侧的3条连接线为预设连接线。
如图8所示，为了进一步防止连接线发生静电击穿现象，所述调整单元41包括第一调整子单元51和第二调整子单元52；所述第一调整子单元51用于当所述连接线32上的实际电压大于第一预设电压时，减小所述连接线32上的电流值。

在具体工作过程中，当连接线32上的电压值大于VGH时，T1导通，此时连接线32上的电流一部分流向第一下拉点44，其余部分流向节点P点之后的连接线32，从而减小了连接线上的电压值。当连接线32上的电压值小于VGL时，T2导通，此时连接线32上的电流一部分流向第二下拉点45，其余部分的电流流向节点P点之后的连接线32（最终流入驱动芯片），从而减小了连接线上的电流值，进而减小了连接线上的电压值。当然，可以理解的，本发明的静电保护模块40也可以采用其他结构的电路。
为了进一步减小连接线的阻抗，所述连接线32的阻抗小于所述柔性电路板30中的走线的阻抗。在一实施方式中，所述连接线32的截面结构包括Mo、Al以及Mo，所述走线的材料为铜。
可以理解的，位于驱动芯片20的右侧的静电保护模块的连接方式与图5或7中的相同，在此不再赘述。
