Abstract
An image display apparatus is provided for reducing occurrences of moving image false-edges by preventing profound changes in “on”/“off” subfield distribution, and for displaying a sharp image that does not appear blurred. This is achieved by effectively dividing one TV field and by displaying a gray level of an input image signal using an “on”/“off” subfield combination, out of possible “on”/“off” subfield combinations for displaying the gray level, in which a number of subfields with large luminance weightings that are “on” is minimized.
