Abstract: A circuit for powering off a liquid crystal panel, a peripheral drive device, and a liquid crystal panel. In the circuit for powering off a liquid crystal panel, a switch module is coupled to an enable signal transmission line, a common electrode and respective data lines of the liquid crystal panel, and is configured to be switched on upon receiving an enable signal, to connect the respective data lines to the common electrode. A peripheral drive device comprises: a reset signal generation module, a first, second and third control module, a data line drive module, a common electrode drive module, and a gate drive module. The reset signal generation module outputs a first reset signal when a driving voltage of a liquid crystal panel is less than a set value. The first control module outputs an enable signal in response to the first reset signal. The second control module drives the gate drive module to scan of gate lines for at least one frame in response to the first reset signal. The third control module, in response to the first reset signal, disconnects the common electrode drive module from the common electrode, disconnects the data line drive module from the data lines, and grounds the data lines and/or the common electrode. The embodiments of the present disclosure can efficiently reduce the start-up and power-off flicker drift of the liquid crystal panel.
