Method of improving a high current of GOA circuit when power on
Abstract:
A method of improving a high current of GOA circuit when power on is provided, including: determining a GOA circuit, wherein the GOA circuit includes a plurality of GOA structure units in cascade, each of GOA structure units includes a pull-up control circuit, a pull-up circuit, a transfer circuit, a pull-down circuit, a pull-down holding circuit and a bootstrapping capacitor, and a pre-charge signal, a first clock signal and a second clock signal are disposed on each of GOA structure units; and pulling up a voltage of the first clock signal and the second clock signal to a predetermined value for a certain time at an abnormal power off moment to discharge the pre-charge signal when detecting the GOA circuit abnormally power off. By practice of the disclosure, the pre-charge signal of GOA structure unit could discharge when the GOA circuit abnormally power off to reduce the high current probability.
