Gate driving circuit and display panel using the same
Abstract:
An embodiment according to the present invention discloses a gate driving circuit and display panel using the same. The circuit includes a driving unit, a control unit, a first negative voltage input, a driving voltage input and a control signal input. Three inputting ends of the driving unit are connected to the different inputs when the status of the driving unit is changed according to the sequence of first cut-off st atus/first driving status/second driving status/second cutoff status. The benefit of the solution is to prevent circuit invalid due to the drain current generating when the oxide thin film transistor works in the depletion mode.
