Abstract
Techniques are disclosed for improving energy efficiency of displays, and in particular, displays capable of selective refresh. In an embodiment, the techniques include adjusting the effective resolution of a display based on the viewer's distance from the display. The effective resolution adjustment can be accomplished by, for example, grouping individual pixels or blurring the display buffer (or both pixel grouping and blurring) based on the viewer's distance from the display. Such an adjustment has the effect of creating enlarged pixels from a plurality of smaller pixels. In any such cases, each of the enlarged pixels (also called macro-pixels) can then be selectively refreshed based on changes from the previous frame. In addition, even if one of the macro-pixels has changed from the last frame, it also need not be refreshed if the viewer would not perceive that change given a subtle or otherwise unperceivable difference in intensity.
