Abstract
A detecting circuit for a panel adapted for detecting a panel which has a grounding loop is disclosed. The detecting circuit for a panel includes a first switch and a first multiplexer. The first switch is electrically connected to the grounding loop and a first ground terminal. The first switch is off in a detecting mode and on in a protection mode. The first multiplexer is electrically connected to the grounding loop and a second ground terminal. In the detecting mode, the current path between a first signal terminal of the first multiplexer and the grounding loop is conducted by the first multiplexer. In the protection mode, the current path between the second ground terminal and the grounding loop is conducted by the first multiplexer.
