Method and system for reducing power consumption in a display
First Claim
1. A method of updating a display, said display comprising a plurality of display elements characterized by a display state, said method comprising:
- in a first mode of operation, periodically re-setting said display state of substantially all said display elements at a first frame update rate so as to display a first series of image frames, said plurality of display elements being arranged as a plurality of pixels of said display, each pixel having two or more display elements; and
changing to a second mode of operation, wherein said second mode of operation comprises periodically re-setting said display state of a first portion of said display elements at a second frame update rate and periodically re-setting said display state of a remaining portion of said display elements at a third frame update rate that is less than said second frame update rate, said changing being triggered by a power level condition,wherein in said second mode, a second series of image frames are displayed at a display element resolution which is less than said display element resolution used to display said first series of image frames, andwherein said second mode comprises periodically re-setting said display state of a first display element in a first pixel at said second frame update rate and periodically re-setting said display state of a second display element in said first pixel at said third frame update rate.

Abstract
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.
