Abstract
A driving circuit of flat display including a charging circuit path, a discharging circuit path, and a detecting circuit is provided. The charging circuit path has first and second impedance states, wherein an impedance value of the first impedance state is smaller than that of the second impedance state. The discharging circuit path has third and fourth impedance states, wherein an impedance value of the third impedance state is smaller than that of the fourth impedance state. The detecting circuit detects whether the charging circuit path or the discharging circuit path is in an unstable first state or stable second state, controls the charging circuit path to the first impedance state or the discharging circuit path to the third impedance state in the first state, and controls the charging circuit path to the second impedance state or the discharging circuit path to the fourth impedance state in the second state.
