Abstract: A gate driver on array (GOA) circuit and a display panel are provided. The GOA circuit provides a pull-up maintaining module including transistors T11, T12, and T13. In a pre-charge sub-phase t1 and an output sub-phase t2, a node Qb is at a high level to pull down a node P and turn off the transistor T13. A node K changes to the high level under control of the transistor T11. The transistor T12 is turned on, and the node Qb is keeping at the high level. A node Qa is keeping at the high level in the pre-charge sub-phase, and keeping at a bootstrap electrical level in the output sub-phase.

Abstract: A display pane, a gate driving method and a display device are provided. The display panel comprises a pixel driving circuit in a display area and a gate driving circuit in a non-display area. The gate driving circuit is electrically connected to a first voltage end and a second voltage end. The first voltage end is configured to turn off a driving transistor of the pixel driving circuit electrically connected to an output end of the gate driving circuit. The second voltage end is configured to turn off an output transistor of the gate driving circuit to suppress the gate voltage shift of the driving transistor in the pixel driving circuit such that the reliability of the driving transistor and the fault tolerance of the display panel could be raised.

Abstract: A multiplexed display panel and device and a driving method for the multiplexed display panel are provided. At the moment when a switching switch is turned on, a potential of a fanout line corresponding to a data line connected to sub-pixels, into which an data signal is input, is adjusted to the same level as a potential of the data line as much as possible, and a potential difference between each fanout line and the corresponding data line is relatively small at the moment when the switching switch is turned on, so that an instantaneous current at this moment is greatly reduced without causing relatively large jump of the potential of the data line, a common electrode and back-plated indium tin oxide (ITO) greatly fluctuate, and then the surface noise generated by the display panel is turned on is greatly reduced.

Abstract: A gate driver on array (GOA) circuit and a display panel are provided. The GOA circuit includes multi-stage cascaded GOA units, and each GOA unit includes a bootstrap module. The bootstrap effect of the bootstrap module is utilized to increase the gate voltage of the output transistor, which can effectively reduce the rise time and fall time of the scan signal output by each GOA unit, thereby improving the charging capability of the display panel.
