Abstract

The present application discloses a gate driver on array (GOA) circuit of a display panel. The GOA circuit includes a first GOA unit comprising a unit-circuitry structure having a pull-up node commonly coupled to three output transistors to control outputting of a first set of three gate-driving signals respectively to a first set of three gate lines associated with the display panel. The GOA circuit additionally includes a second GOA unit comprising a substantially same unit-circuitry structure cascaded with the first GOA unit and configured to control outputting a second set of three gate-driving signals respectively to a second set of three gate lines associated with the display panel. Moreover, the GOA circuit includes a capacitor connected from one in the second set of three output terminals of the second GOA unit to the pull-up node of the first GOA unit.
