1. a low power source driving device is used for the load on liquid crystal driver (100) driving display panels (200), it is characterized in that comprising:

  • Sequential control digital circuit (120), it is at a gate line time (T Grid) in produce different digital signal combinations (AP0~

    APX), and the combination of described digital signal (it is 1 that AP0~

    APX) only has the logic current potential of a digital signal at one time;

    The dynamic source electrode driver bias circuit of adjusting (130), (AP0~

    APX) produces the bias current (I of different simulation current potentials according to aforesaid described digital signal combination for it The source electrode bias voltage);

    And Multiple source driver (110), it is subjected to aforesaid bias current (I The source electrode bias voltage) control, produce corresponding output driving force, make the load of described display panels (200) can be at a gate line time (T Grid) in climb or drop to the gamma voltage current potential of appointment.
