Abstract: A display panel and a method of driving the same are disclosed. The display panel includes a shift register with a plurality of stages configured to shift and to output a scan pulse for a plurality of scan lines. Each stage includes a pull-up transistor and a pull-down transistor coupled in series and defining an output node therebetween, a driver with a first node coupled to a gate electrode of the pull-up transistor and a second node coupled to a gate electrode of the pull-down transistor; and a node controller coupled to the first node, the second node, and the output node. In each stage, the node controller is configured to selectively apply a reference voltage at the first node and the second node in response to a control signal.
