Abstract
Provided are a display driving circuit, a display device and a driving method thereof, which are capable of avoiding an influence of a feed through effect on a voltage difference between a pixel electrode and a common electrode and thus improving the quality of a displayed picture. The display driving circuit comprises a gate driving unit for controlling a thin film transistor TFT to be turned on, a source driving unit for outputting a signal to a source of the TFT, and a circuit unit for supplying a power to a common electrode, the circuit unit outputs a first voltage to the common electrode when the TFT is in a turn-on state, and the circuit unit outputs a second voltage to the common electrode when the TFT is in a turn-off state, wherein the first voltage is a voltage different from the second voltage.
