Device and driving method for displaying image

PURPOSE: An image display device and method are provided to detect a dominant color in a unit frame image and adaptively change the sequence of color implementation according to a detection result. CONSTITUTION: An image analysis part (110) outputs an input image with a unit frame by adding an insertion frame to the image with a color sequence, which is classified into R frame, G frame, and B frame, and changing the position of the insertion frame based on at least one color dominant in proportion in the unit frame. A display panel (140) receives an image with the color sequence containing the insertion frame from the image analysis part and displays the image. A backlight unit receives information about the color sequence containing the insertion frame from the image analysis part and provides light having a color corresponding to the color sequence containing the insertion frame according to the information.
