<p>A method of refreshing an image on a display device includes receiving an image to be displayed (810) at a display (110); processing said received image to obtain at least one image parameter relating to said image to be displayed (810); and varying a rate (930) at which said displayed image is refreshed based on said image parameter. A video or image display device, and a display driver, have also been described.This provides the following advantages that the refresh rate is constantly being varied in response to the images being displayed so as to constantly minimise the power consumption of the display device without noticeable flickering of the display device. Furthermore, the quality of the image is maintained at a continuous level, irrespective of the changes in, for example the complexity or number of colours used in a particular image.</p> |
