Abstract
The present invention discloses a driving method and a driving circuit of a liquid crystal panel, which relates to the field of liquid crystal displaying technology, and solves the problem of the ion accumulation in a TFT channel. The driving method of a liquid crystal panel according to embodiments of the present invention comprises: inputting an offset pinch-off voltage to gate scan lines of each row within a vertical blanking period between two successive frames, the offset pinch-off voltage being an original pinch-off voltage plus a predetermined voltage offset; and inputting the original pinch-off voltage to the gate scan lines at the time other than a gate turn-on time and the vertical blanking period. The embodiments of the present invention are mainly applied to the field of displaying of liquid crystal panels.
