Panel disconnection detection device

A panel disconnection detection device includes a panel and a detection circuit. The panel includes a display area, a conductive mesh line, a gate line, and a data line. The conductive mesh line, the gate line, and the data line are located in the display area. The conductive mesh line is configured to transmit a direct current (DC) signal. The gate line is configured to transmit an alternating current (AC) signal. The data line is configured to transmit a data signal. The detection circuit is coupled to the conductive mesh line, the gate line, and the data line in the display area. The detection circuit includes a first sub-detection circuit, a second sub-detection circuit, and a third sub-detection circuit. The first sub-detection circuit is coupled to the conductive mesh line, and is configured to generate a first detection signal so as to detect whether the conductive mesh line is broken. The second sub-detection circuit is coupled to the gate line, and is configured to generate a second detection signal
