Patent ID: 8912828

Claim:
A driving circuit of a flat display, having an output terminal for driving pixels of a display panel to display, and comprising: a charging circuit path, configured to charge the pixels of the display panel, and having a first impedance state and a second impedance state, wherein an impedance value of the first impedance state is smaller than an impedance value of the second impedance state; a discharging circuit path, configured to discharge the pixels of the display panel, and having a third impedance state and a fourth impedance state, wherein an impedance value of the third impedance state is smaller than an impedance value of the fourth impedance state; and a detecting circuit, detecting whether or not the charging circuit path or the discharging circuit path is in a first state of a charging/discharging stage or in a second state with voltage approaching to a stable state, wherein in the first state, the detecting circuit controls the charging circuit path to the first impedance state or controls the discharging circuit path to the third impedance state, and in the second state, the detecting circuit controls the charging circuit path to the second impedance state or controls the discharging circuit path to the fourth impedance state.
