<p>Provided are a gate drive circuit, an array substrate of same, and a display panel. The gate drive circuit comprises multiple levels of gate drive units, each level of gate drive unit comprising a start unit (10), an energy storage unit (20), a pull-up unit (30), a first pull-down unit (40), and a second pull-down unit (50). The second pull-down unit (50) is coupled to the energy storage unit (20) and a gate line, and is used to intermittently generate a second control signal (K2) according to a drive voltage (Q(N)), a time pulse signal (CK1), and a second reference voltage (Vss2), so as to pull the drive voltage (Q(N)) and a gate signal (G(N)) on the gate line down to the second reference voltage (Vss2). In addition, to prevent a leakage current between a first reference voltage (Vssl) and the second reference voltage (Vss2), a transistor, through which a leakage current possibly flows, between the first reference voltage (Vssl) and the second reference voltage (Vss2) is replaced with multiple cascaded transistors, so as to avoid electric leakage. The gate drive circuit and the array substrate of same are enhanced in reliability, are prolonged in service life, and can be applied to various display panels.</p> |
