Patent ID: 7193598

Claim:
A noise suppressing method for a flat panel display driven by a time controller and a plurality of driver IC's, the noise suppressing method comprising: providing a signal detect circuit and a video signal processor; and detecting whether a signal input to the flat panel display is stable by the signal detect circuit when the flat panel display is switched-on, and when the signal is unstable, controlling the driver IC's to output a black burst signal by the video signal processors, wherein when the flat panel display is driven with a normally white type, a voltage differential between a white signal V white and a common voltage V common applied to the flat panel display is smaller than a voltage differential between a black signal V black and the common voltage V common , such that the video signal processor controls the driver IC to output the black signal V black with a larger voltage differential from the common voltage V common so as to display a black burst when the flat panel display is switched-on.
