ABSTRACT:
A display arrangement includes a memory for storing image signals of one field supplied to an LCD display section, a comparator for determining whether the image signals of the next field to be supplied to the LCD display are those for a fixed image display or a changing image display by comparing those image signals with the image signals of the preceding field stored in the memory, and a controller for controlling a display driver so that, when the comparator determines that the image signals are for a fixed image display, the driver drives the LCD panel in a reduced-power drive mode. In one embodiment, the reduced-power drive mode is a spread-out mode and, in another embodiment, the reduced-power drive mode is a low-voltage mode.
