An image display device is presented to solve problems of high power consumption, insufficient contrast, image flicker, and distortion of image display devices. The image display device includes an image display management module which includes a backlight control unit. The backlight control unit includes an image brightness analyzer, generating a brightness value according to an input image data; a weight generator, generating a weight according to the brightness value; an image variation analyzer, analyzing the input image data to generate an image variance; and a backlight factor generator, coupled to the weight generator and the image variation analyzer to generate a backlight adjusting signal according to the weight and the image variance. By the backlight adjusting signal, the image display device achieves the power-saving and contrast enhancement effects.
