Abstract
In order to reduce power consumption of a display device when a still picture is to be displayed, a display area of the device is subdivided into a plurality of Still Picture Refresh Groups (SPRGoP's), with each SPRGoP consisting of n pixels. All n of the pixels are charged in every one of sequential frames when a motion picture mode is in effect. Less than all of the n pixels of each SPRGoP are refreshed in each frame of an N-frame refresh cycle when a still picture mode is in effect. Different schemes for cycling through the n pixels of each SPRGoP are disclosed.
