Abstract

See full text

A method and system for reducing power consumption in a display includes driving a display comprising a plurality of display elements characterized by a display state. In a first mode of operation, the display state of substantially all the display elements is periodically re-set so as to display a first series of image frames. Upon changing to a second mode of operation, a second mode of operations comprises re-setting the display state of only a portion of the display elements so as to display a second series of image frames at a display element resolution which is less than said display element resolution used to display said first series of image frames.
