Detecting circuit and display panel

A display panel comprising a detecting circuit, the detecting circuit being configured to apply to an array substrate comprising a gate driver on array (GOA) circuit, wherein the GOA circuit comprises a first GOA module and a second GOA module arranged at two sides of a display area of the array substrate, and the display area is lit up when a driving signal is input to either the first GOA module or the second GOA module;

• the detecting circuit comprises:
• a driving signal output module, a first switch module and a switch control module;
• a first terminal of the first switch module is connected to an output terminal of the driving signal output module, a second terminal of the first switch module is connected to an input terminal of the first GOA module, a control terminal of the first switch module is connected to a first control output terminal of the switch control module, and the first control output terminal is configured to control turning on/off of the first switch module.
