Abstract:
본발명은표시패널과고객시스템은연결하기위한구동인쇄회로기판(PCB)으로서, 구동 PCB의커낵터부에는구동 PCB가고객시스템에연결되지않을때에는전기적으로플로우팅되어있는더미접지패드가포함되는바, 그러한더미접지패드를인접한접지패드또는접지금속패턴과전기적으로연결함으로써, 구동 PCB가고객시스템과연결되지않은상태에서도 ESD, EOS 등의외부전기적충격으로부터표시패널또는구동회로부가손상되는것이방지할수 있는효과가있다.
Abstract(Chinese):

本发明涉及一种用于连接显示面板和客户端系统的驱动印刷电路板（PCB）。 驱动PCB的连接器包括虚拟接地焊盘，当驱动PCB连接到客户端系统时，该接地焊盘电浮动。 虚拟接地焊盘电连接到相邻的接地焊盘或接地金属图案。 因此，即使驱动PCB没有连接到客户端系统，本发明防止显示面板或驱动电路部件被诸如ESD，EOS等的外部冲击损坏。

Abstract(English):

The present invention is a display panel with the customer system is a bar included in a dummy ground pads which are plated flow electrically when the the driving PCB as a driver printed circuit board (PCB) for connecting, keonaek taboo of the driving PCB may not be connected to the customer system, such pile by connecting the ground pad to the adjacent ground pad or a ground metal pattern and electrically, the drive PCB is to be prevented even in a state that is not associated with a customer system is damaged ESD, a display panel or a driving circuit from an external electric shock, such as EOS there is an effect that it is possible.
