Zusammenfassung:	The present invention relates to a driving printed circuit board (PCB) for connecting a display panel and a client system. The connector of the driving PCB includes a dummy ground pad which is electrically floated when the driving PCB is connected to the client system. The dummy ground pad is electrically connected to an adjacent ground pad or ground metal pattern. Thereby, even though the driving PCB is not connected to the client system, the present invention prevents the display panel or the driving circuit part from being damaged by external shocks such as ESD, EOS, etc. 본 발명은 표시패널과 고객 시스템은 연결하기 위한 구동 인쇄회로기판(PCB)으로서, 구동 PCB의 커낵터부에는 구동 PCB가 고객 시스템에 연결되지 않을 때에는 전기적으로 플로우팅되어 있는 더미 접지 패드가 포함되는 바, 그러한 더미 접지 패드를 인접한 접지 패드 또는 접지 금속 패턴과 전기적으로 연결함으로써, 구동 PCB가 고객 시스템과 연결되지 않은 상태에서도 ESD, EOS 등의 외부 전기적 충격으로부터 표시패널 또는 구동 회로부가 손상되는 것이 방지할 수 있는 효과가 있다.
