1. A system for displaying image data, the system comprising:
- a display device comprising a plurality of display elements arranged as a plurality of rows of pixels of the display device, wherein the display device is configured to operate at a plurality of selectable operational modes; and
an array controller capable of receiving image data from an image data source, the array controller configured to provide image data to the display device such that in a first operational mode corresponding to a first display frame rate, a first and second subset of rows of display elements are updated at a first rate, and in a second operational mode corresponding to the same or lower display frame rate than the first display frame rate, the first subset of rows of display elements are updated at the first rate and the second subset of rows of display elements are updated at a second rate that is less than the first rate, 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 lower update rate without changing a 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 having selectable resolution, wherein the display device is configured to operate at a plurality of selectable operational modes. In a first operational mode, data at a first resolution is provided to the display at a first data rate, and in a second operational mode, data at a second resolution is provided to the display at a second data rate.
