Abstract: A field-sequential display is operated in one of a color mode or a grayscale mode. In the color mode, a video source provides image content in the form of multiple-color image data having a frame rate of X Hz and a display controller uses the multiple-color image data to drive the field-sequential display so as provide multiple-color image content at the field-sequential display. In the grayscale mode, the display controller generates grayscale image data from the multiple-color image data and the display controller then drives the field-sequential display with the grayscale image data at a lower frame rate of Y Hz. While in the grayscale mode, the display controller can take advantage of the enhanced contrast provided by the grayscale image content to reduce or disable backlighting at the field-sequential display. The reduced timing requirements afforded by the lower frame rate, as well as the reduction or elimination of backlighting, can reduce power consumption compared to the color mode.
