1. A system for displaying image data, said system comprising:
- a display device having a plurality of operational modes, at least some of said operational modes corresponding to reduced display element resolution when displaying image data on the display device; and
a source of image data configured to provide image data to said display device at a data rate that depends at least in part on the mode in which said display device is operating,wherein the plurality of operational mode includes a first operational mode and a second operational mode, wherein the second operational mode corresponds to reduced display element resolution as compared with the first operational mode, wherein the first operational mode includes displaying image data in a display region of the display device, and wherein the second operational mode includes displaying image data at a reduced display element resolution without changing the size of the display region.

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 for displaying image data, said method comprising:
-
re-setting a plurality of display elements in a first mode of operation to display image data, re-setting less than all of the plurality of display elements in a second mode of operation to display image data, said second mode corresponding to a reduced display element resolution, and receiving image data for display at a data rate that depends at least in part on the mode of operation being used, wherein the first mode of operation includes displaying image data in a display region, and wherein the second mode of operation includes displaying image data at a reduced display element resolution as compared with the first mode without changing the size of the display region. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A method of providing image data for display, said method comprising:
-
receiving data describing a current display mode being used by a display device, wherein the current display mode comprises updating display states of less than all display elements in the display device to provide a reduced display element resolution; filtering image data for display on the display device; and sending the filtered image data over a communications network, wherein the filtering comprises filtering the image data so that image data for non-updated display elements is not sent, wherein the display device has a first display mode different from the current display mode, wherein the current display mode corresponds to reduced display element resolution, wherein the first display mode includes displaying image data in a display region of the display device, and wherein the second display mode includes displaying image data at a reduced display element resolution as compared with the first display mode without changing the size of the display region. - View Dependent Claims (25, 26)

27. An apparatus for displaying image data, the apparatus comprising:
-
an array of display elements having a plurality of operational modes, at least some of said operational modes corresponding to reduced display element resolution when displaying image data using the array; a network interface configured to receive information from a content server over a communications network; and an array controller configured to provide data to the array based on the information received from the content server, wherein the plurality of operational modes includes a first operational mode and a second operational mode, wherein the second operational mode corresponds to reduced display element resolution, wherein the first operational mode includes displaying image data in a display region of the display device, and wherein the second operational mode includes displaying image data at a reduced display element resolution as compared with the first operational mode without changing the size of the display region. - View Dependent Claims (28, 29, 30, 31, 32)
