摘要： A sub-field driving method for a display device in which two lowest-intensity sub-frames adjacent to each other are selectively turned ON in accordance with the change of image brightness along the time base. When the level of an original signal changes from 7 to 8 or vice versa, for example, SF3, SF2, and SF1 are selected as the sub-frames corresponding to the level 8, and SF3, SF2 and SF1 are selected as the sub-frames corresponding to the level 7. Therefore, since ON or OFF at the levels 7 and 8 does not continue, a great change of brightness does not occur at this time and image quality is maintained. A circuit for applying the above method includes a correction circuit comprising a frame memory (24) for providing one-frame delay, a correction constant setting circuit (26) for outputting correction data and an addition circuit (28) for adding correction data to original image signals to remove distortion of a dynamic image (false profile).
