FIELD: physics.
SUBSTANCE: microcircuit includes a trigger circuit, the first selective input circuit, the second selective input circuit that is used to pass the high level input signal for the common electrode and the high level input signal for the gate electrode to the trigger output of the trigger circuit in different time sequences to raise the voltage on the output terminal of the start-up circuit, the third selective input circuit used to select the level signals or front signals on the gate line n+1 and the gate line n+4 as a signal for restarting the trigger circuit, the fourth selective input circuit, which is used to lower the voltage therein, a selective output circuit, the input of which is connected to the output terminal of the start-up circuit, for selective output of the excitation signal of the gate electrode or the excitation signal of the common electrode.
EFFECT: decreasing the through-voltage to improve the quality of the gray scale on the display.
