Abstract
The present disclosure relates to a display panel having a gate driving circuit and a method of monitoring characteristics of the gate driving circuit, and the gate driving circuit includes a test transistor connected to at least one of a pull-up transistor and a pull-down transistor. The test transistor is turned on in response to a gate on voltage of a test enable signal generated in a measurement mode to form a closed loop including at least one of the pull-up transistor and the pull-down transistor.
