A video or image display device (100) includes a display (110) for displaying an image and display refresh circuitry (200), operably coupled to the display (110), to refresh an image on the display (110). A processor (108), operably coupled to the display (110) and display refresh circuitry (200), processes a received image to determine an image type to be displayed. The processor (108) then varies or halts a clock signal provided to the display refresh circuitry dependent upon the image being displayed.This provides the advantage that the refresh rate is varied or halted in response to the type of image being displayed, to constantly minimise the power consumption of the display device without noticeable flickering of the display device. |
