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 local illumination calculation unit calculating a target amount of the light generated from the sections based on a brightness of a (n+1)-th (n is an integer larger than 1) frame of the frames; a backlight controller controlling the backlight unit based on the calculated target amount of the light; a frame interpolator generating at least one (n+1)-th sub-frame based on the (n+1)-th and an n-th frame previous to the (n+1)-th frame and sequentially outputting the (n+1)-th frame and the (n+1)-th sub-frame; and a pixel adjuster adjusting a light transmittance of the pixels according to a pixel brightness of the (n+1)-th frame and the (n+1)-th sub-frame and the calculated target amount of the light.
