1. A method for controlling a power regulator comprising:

  • receiving, during a first cycle corresponding to a display duration of a current image, future image property information related to a future image to be displayed on a display during a second cycle after display of the current image, said second cycle occurring after said first cycle;

    generating a power regulator control signal, prior to said second cycle and prior to display of the future image, based upon the future image property information; and

    precharging a power regulator output voltage based on the power regulator control signal, prior to said second cycle by a duration of time that depends on the future image property information, and prior to the power regulator output voltage dropping below a threshold value, said power regulator output voltage coupled to a switch that assists in displaying said future image on said display during said second cycle.
