Abstract
A gate driver on array (GOA) circuit includes a plurality of GOA units in cascade. Each of the GOA units includes a pull-up control module, a pull-up module, a capacitor module, pull-down maintenance module, a pull-down module, and a GOA drive shutdown module. The pull-up control module is connected to a signal output terminal G(N−3) of a (N−3) stage GOA unit, a constant-voltage high-potential signal terminal, and a first node, wherein N is a natural number. The gate shutdown signal terminal is configured to provide a low potential signal during a display period and is configured to provide a high potential signal during a touch period, when the gate shutdown signal terminal provides the low potential signal, the pull-down maintenance module maintains a pull-down maintenance function, and when the gate shutdown signal terminal provides the high potential signal, the pull-down maintenance module becomes is disabled.
