More Information
Summary:The invention discloses an image display method and device, and the method comprises the steps: receiving an input image, dividing the image into a plurality of first subareas, and respectively calculating the average value of brightness corresponding to each first subarea; determining at least one second sub-region from the plurality of first sub-regions, wherein the average value of the brightness of the second sub-region is smaller than a preset brightness threshold value; determining an association factor corresponding to each second sub-region based on a preset start control depth, a preset brightness threshold and an average value of brightness corresponding to each second sub-region in the at least one second sub-region; compensating the average value of the brightness correspondingto each second sub-region based on the correlation factor to obtain a compensated brightness value; and adjusting the backlight value corresponding to each second sub-region based on the compensatedbrightness value, and disp
