The technical solutions allows the trigger signal of the (n+1)th shifting register unit stage to be provided by the first clock signal transmitted from the INPUT_NEXT terminal of the nth shifting register stage, and it can avoid the delay due to the trigger signal of the (n+1)th shifting register unit stage being provided by an output signal of the nth shifting register unit stage, and it can solve the technical problem that the display lines close to the bottom of the display panel can not operate normally due to the accumulation of the delays. Further, after the nth shifting register unit stage outputs the output signal and before the next input signal arrives, the pull-down node remains at high-level under the alternating control of the two clock signals. Thereby, it can be ensured that the pull-up node PU and the output terminal continue to be discharged, and thus the problem that the lifespan of the third thin-film transistor is affected by the frequent switching-on thereof can be solved. | 03-20-2014 |
