Abstract
A detection circuit and a scan drive circuit are provided. The detection circuit includes a comparison circuit and a determination circuit. The comparison circuit is configured to receive a low-level voltage and a scan output signal output from an nth level buffer, and generate a first intermediate signal according to the scan output signal and the low-level voltage signal. The determination circuit is configured to receive the first intermediate signal and the scan output signal of the nth level buffer output from the output terminal of the nth level buffer in the scan chip, and generate a control signal according to the first intermediate signal and the scan input signal, and output the control signal to the scan chip to control the scan chip to cut off output when a short circuit occurs.
