A technique analyzes an image to be displayed on a screen, before it is displayed, to determine a current draw of that image on the screen. Based on this analysis, adjustments can be made to the circuitry so that when the image is displayed, it is done so more efficiently. In a specific implementation, a DC-to-DC converter includes two boost converter circuits. Based on the analyzed image, the technique turns on a single boost converter when the current draw of that image is below an identified current threshold level, and turns on two boost converters when above the identified current threshold level.

Operating multiple DC-to-DC converters efficiently by using predicted load information

A method for driving a display device comprises processing a plurality of sequent frame data by a graphics controller. The graphics controller is capable of optimizing a frame rate and outputting a first plurality of display signals at the frame rate. And then, a timing controller is used to convert the first plurality of display signals into a second plurality of signals at a predetermined refresh rate.
