Claim:
A display comprising: a display panel; a backlight arranged corresponding to each of sub regions, and selectively illuminating the corresponding sub region, the sub regions being defined by dividing a display region of the display panel into a plurality of parts; a monitoring means for monitoring light emission state of the backlight corresponding to each of the sub regions, wherein the light emission state includes a cumulative light emission time of the backlight for each sub region; and a display control means for: determining a difference of the cumulative light emission time between a backlight with the longest cumulative light emission time and a backlight with the shortest cumulative light emission time; comparing the difference to a predetermined threshold value; determining, when the difference is more than a predetermined threshold value, a sub region on which an image is to be displayed, to fit the image into the determined sub region; and controlling a backlight corresponding to the determined sub region to emit light.
