Abstract:
1. A display apparatus, comprising: a backlight unit having a plurality of sections each generating a light; a display unit having a plurality of pixels allowing the light to pass therethrough; an image signal receiver receiving an image signal having a plurality of consecutive frames to sequentially output the frames; a frame interpolator generating at least one (n+1)-th sub-frame (n is an integer larger than 1) by applying, to an (n+1)-th frame, a difference value between an n-th frame and the (n+1)-th frame, and sequentially outputting the (n+1)-th frame and the (n+1)-th sub-frame, wherein the n-th frame corresponds to a former frame and the (n+1)-th frame corresponds to a latter frame; a local illumination calculation unit calculating a target light amount generated from the sections based on a brightness of the (n+1)-th frame; and a backlight controller controlling the backlight unit to generate the target amount of the light from the sections while the (n+1)-th frame and the (n+1)-th sub-frame are being displayed.
