METHOD AND DEVICE FOR REDUCING POWER CONSUMPTION IN A DISPLAY
First Claim
1. A method of updating a display, the method comprising:
- applying a series of row voltage strobes to a first set of rows of display elements during a first display write operation so as to configure display elements in said first set of rows to a first selected state; and
skipping subsequent row voltage strobes to said first set of rows during subsequent display write operations that set the remaining rows of the display in accordance with received display data.

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.

17. A method of updating a display, the method comprising:
-
transitioning a set of column voltages to a first set of columns of display elements during a first display write operation so as to configure display elements in said first set of columns to a selected state; and skipping subsequent column transitions to said first set of columns during subsequent display write operations that set the remaining columns of the display in accordance with received display data. - View Dependent Claims (18, 19, 20, 21, 22)

23. A display device, comprising:
-
an array of display elements configured as a plurality of rows; a battery configured to provide power to the array; and an array controller configured to apply a series of row voltage strobes to a first set of rows of the array during a first display write operation so as to configure display elements in said first set of rows to a first selected state; wherein the array controller is further configured to skip subsequent row voltage strobes to one or more of the rows in the first set of rows based on a power level condition of the battery during subsequent display write operations that set the remaining rows of the display in accordance with received display data. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
